Características morfométricas y merísticas del bonito argentino
Provedor de dados: 20
Autores: Hansen, J.E.
Collete and Chao (1975) reviewed the systematic and morphology of the Genus Sarda and relatives ((Tribe Sardini), including into their analysis a few S.sarda from the SW Atlantic. Before that, Demir (1964)dealt with the meristic data of the same species from the Black Sea. This paper in concerned with the featuring of the bonito caught in Argentina, from both a morphometric and a meristic point of view. The study made the differences reported by Collette and Chao (op.cit.)among W and E S.sarda populations to be more conspicuous, because our samples had even lower values han those from the NW.

Autores: Villacrés, J.; Goyes A., P.
En este trabajo se presentan los resultados de los análisis realizados sobre los sedimentos superficiales de fondo en Bahía Chile, Isla Greenwich, desde el punto de vista granulométrico y mineralógico. En un total de 18 muestras del área se observa una predominancia de limos muy mal seleccionados, platicúrticos y con asimetría hacia los tamaños finos. Mineralógicamente, se observa mayor concentración de minerales livianos sobre los pesados, con altos porcentajes de fragmentos de rocas igneas, deduciéndose que son sedimentos inmaduros y que el área fuente se encuentra en una zona cercana. Los sedimentos depositados en la bahía son de orígen mixto: Procedentes de la erosión de las formaciones costeras y en menor porcentaje, del aporte de organismos marinos....

Tanzanian Coastal and Marine Resources: Some Examples Illustrating Questions of
Provedor de dados: 20
Autores: Francis, J.; Bryceson, I.
The coast of Tanzania is characterised by a wide diversity of biotopes and species, typical of the tropical Indowest Pacific oceans, and the peoples living there utilise a variety of its natural resources. Because of the extent of the diversity and variety, several different examples are used by this study to elucidate the complexity of issues and multiplicity of management responses related to use of coastal and marine resources. It emerges that coastal management requires an integrated cross-sectoral approach to address the wide array of interrelated issues involved.

Reversing Bottom Circulation in the Somali Basin
Provedor de dados: 20
Autores: Molinari, R.L.; Beal, L.M.; Chereskin, T.K.; Robbins, P.E.
Two sets of direct velocity measurements were taken, concurrent with hydrographic data, in the bottom waters of the northern Somali Basin in June and September, 1995. The velocities indicate a temporal flow reversal in the bottom circulation, which is consistent with the changing density structure between the sections. In June, there is evidence of a southward Deep Western Boundary Current with a transport of 5 Sv. By September, flow close to the boundary is northward, with a transport of 2.6 Sv. Furthermore, the deep density gradient across the interior of the Somali Basin also changes between occupations, implying a cyclonic circulation in June and anticyclonic flow in September. Rossby wave activity is high in this region during the southwest monsoon,...

Two experiments were accomplished with wild P. argus lobster postlarvae collected from the sea in pelagic collectors. In the first one, the effect of two foods (live and frozen Artemia) was tested on 0.17 g lobsters in a 40 days feeding trial. Significant differences were found (p&lt;0.05) between the final weight, survival, weight increment, molting rate and NBI, the highest values were for live Artemia with the highest survival (93%). Mortalities using frozen Artemia were almost entirely attributable to cannibalism of postmoult lobsters. In the second experiment, the average initial weight was 0.26 g during 120 days and three densities (50, 70, 90 n/m2) were tested, the feeding regimes were live Artemia and pellet during 60 days the rest of time with...

The littoral oyster Crassostrea cucullata occurs between 1.05-3.35 m above chart datum with the highest density occuring between 1.85-2.75m. Its distribution is size-related as demonstrated by computation of correlation coefficients (r) and regression equations. The shell lengths (i.e. maximum linear dimension) decreases in an upshore direction. The analysis show high r-values which are significant at P&lt;0.001. The elevation and density related effects on the shell lengths of the oysters are discussed.

Correction of seabed layer thickness in processing subbottom profile data.

Autores: Wang, Fangqi; Qi, Faqing; Hu, Guanghai; Dong, Lifeng; Tao, Changfei.
The subbottom profiling is an important means of marine engineering survey, hazardous geology study and continental shelf scientific research. The accuracy of subbottom profile data interpretation has a direct impact on the research and investigation results. Because some of profilers’ transducer and hydrophone are separately installed, when the survey area is very shallow, distortion of shallow layers will be caused if it is seen as a self-excited and self-collected single-channel seismic system. According to the principle of subbottom profiler, the distortion correction formula is deduced and analyzed, providing actual value to using C-View software to interpret such subbottom profile data more accurately. In addition, the seabed sediments sound velocity...

Emerging Africa: The Case of Ghana
Provedor de dados: 20
Autores: Kwasi Fosu, A.
The growth record of Ghana has been one of unevenness, as Table I.1 and Figure I.1 clearly indicate. With a reasonably high GDP growth in the 1950s and early 1960s, the Ghanaian economy began to experience a slowdown in GDP growth as of 1964. Growth was turbulent during much of the period since the mid-1960s and only began to stabilize by 1984. In 1966, 1972, 1975-1976, 1979, 1980-1983, the growth rate was negative. The years in which negative growth was experienced generally coincide with change in government and sometimes with policy changes or reversals. Negative growth was first recorded during the time of the first coup d’etat, with a forceful transfer of authority from the dictatorial Nkrumah regime to the military headed by General Ankrah. The...

Activite des embarcations impliquees dans la peche a la ligne a main aux Seychelles
Provedor de dados: 20
Autores: Bach, P.
Fishing performances of four different types of boats (pirogues, outboard, whalers, schooners) are studied through the analysis of the temporal evolution, between July 1985 and June 1988, for four parameters: numbers of active fishing boats,- total number of fishing trips, - average number of trips/boat, - average trip duration. The trends from these analysis reveals that the boats involved in the handline fishery in seychelles have evolved considerably. These changes must be taken into consideration in the case of an eventual reorganisation of the fleet.

Provedor de dados: 20
Autores: Mzighani, S.
The fecundity and population structure of the cockle, Anadara antiquata L., from sandy/muddy intertidal habitats in the intertidal of Ocean Road beach was examined from January to December 2001. A. antiquata is hand harvested, for domestic consumption, mainly by women and children, with the empty shells sold to traders. The sex ratio from combined data of all classes deviates significantly from 1:1 with the ratio of females to males increasing significantly above 41 mm shell length. Hermaphrodites were also observed in this size range indicating a protrandric hermaphrodite situation with males maturing earlier than females. Fecundity increases with an increase in shell length, with a mean of 1,652,000 (+/- 562,000 [or 40%] SE) eggs per female and...

Provedor de dados: 20
Autores: Méndez, S.M.
Las floraciones algales nocivas (FANs) afectan la salud humana, la economía pesquera, el turismo y los ecosistemas acuáticos. Dado que el problema de las FANs es mundial, para minimizar sus efectos se han implementado programas de monitoreo en más de 50 países. El registro de especies de fitoplancton tóxico ha ido creciendo y cada vez se conoce más diversidad de toxinas producidas por estos microorganismos. En Uruguay, la Dirección Nacional de Recursos Acuáticos (DINARA) dependiente del Ministerio de Ganadería Agricultura y Pesca (MGAP) lleva a cabo el monitoreo simultáneo de las FANs y la toxicidad en los moluscos. Esta modalidad de monitoreo y la confirmación de la toxicidad de algunas especies de microalgas, permite establecer la relación de causalidad...

Global climate change and the vulnerability of the Nigerian coastal zone to accelerated sea level rise: Impacts and responds.
Provedor de dados: 20
Autores: Ibe, A.C.
In the recent past, climatic changes and variations have occurred in Nigeria with resulting adverse socio-economic impact. From these experiences, it is inferred that the expected change in global climate will have far reaching disastrous consequences for Nigeria if appropriate anticipatory technical and policy Measure are not taken. More recent results from various models based on an eventual warming from a doubling of greenhouse gases of between 1.5 and 5oC by the end of the 21st century predict an acceleration of the eustatic rise in sea level from 1.2-1.5mm/yr. over the last hundred year s to 4 – 6mm/yr. although previous estimates were much higher [e.g.56–3.68m by the end of the 21 century] on the low lying Coastal zone of Nigeria, which is rich in...

Autores: Drweesh, M.A.; Salem, D.M.S.A.
The rate of reduction of Cr6+ to Cr3+ reaction in K2Cr2O7 has been studied and it is found to be first order. The rate of reaction at 0.05 mole of K2Cr2O7 have been measured in absence of quaternary ammonium salts as CTAB (Cetyl trimethyl ammonium bromide) and CPYB (Cetyl trimethyl pyridinium bromide). The rates of reaction are also measured in presence of CTAB and CPYB at four different temperatures (25, 30, 35 and 40oC). Effects of rotations are also studied. The rate of reaction was decreased by addition of salts. Thermodynamic parameters ∆G*, ∆H* and ∆S* are given.

Kenya, Reef Status And Ecology
Provedor de dados: 20
Autores: Mwachireya, S.; Uku, J.N.; Mdodo, R.; Obura, D.; Wawiye, P.
Coral reefs along the entire coast of Kenya suffered widespread bleaching and mortality of corals during the first half of 1998 (Wilkinson, 1998; Obura, 1999; McClanahan et al., 1999). This status report summarises findings relating specifically to coral bleaching, mortality and effects on benthic community structure. In addition, preliminary results from a number of research projects investigating different aspects of the bleaching event are reported here. In shallow waters, on a per-area basis, most of Kenya’s southern fringing reefs have lost between 66% and 80% of their live corals. Coral reefs in deeper water suffered less mortality due to lesser exposure to higher temperatures. Reefs on the northern part of the coast, influenced by cold water...

To understand sedimentation processes at Salmedina Reef Banks during the annual cycle, three cylindrical sediment traps were installed on the flat top of the reef Banks at mean depth of 8.5 m. Cylinders were collected monthly between July, 2003 and September, 2004. The trap content was analyzed by bulk composition and the composition of biogenic calcareous particles from the sand fraction. Results were compared with environmental parameters of the area trough the same time span. Sedimentological variables were analyzed with emphasis on terrigenous supply and relative percentages of calcareous components related to location and physical parameters. It was found that the totality of sedimentation, terrigenous contribution included, was concentrated during...

Vertical structure and floristic diversity of forest islands in the coastal plain of southern Togo have been studied. Eleven plant communities and five types of vertical structures could be described. Calculation of the Shannon indices shows that their floristic richness and diversity in the lower stratas (&lt;7 m) are very important while highers (&gt;I5 m) are floristically poor and less divers. Compared to other regional forests, the islands in the coastal plain of southern Togo are identical to those in the south of the Republic of Benin but are different from the forest types found west and east of the Dahomey gap

Preliminary investigation on the Pleistocene/Holocene Sea-Level Changes along the Coastline of Tanzania, with reference to Unguja and Pemba  Islands
Provedor de dados: 20
Autores: Nyandwi, N.; Muzuka, A.N.N.; Shaghude, Y.W.
Along the coast of Tanzania, coral reefs, marine terraces and beach ridges are among the most important geomorphological features indicative of the Pleistocene/Holocene sea level changes. Three major terrace units can easily be identified on the mainland coast, namely, Mtoni (youngest), Tanga and Sakura (oldest). Three terrace units have also been identified on the Islands of Unguja and Pemba. On the basis of the difference in the terrace elevations between the two terrace systems it is postulated that the marine terraces on the islands probably represent minor fluctuations of sea level, rather than major phases of sea level fluctuation. A sand beach on the seaward side and several sand ridges on the landward side represent the Recent phase. The oldest...

Autores: Ivanovic, M.L.; Brunetti, N.E.
The diet of red squid (Ommastrephes bartramii)during autumn 2001 and2002 in the SW Atlantic region off Argentina and Uruguay (33° S-42° S;46° W-55° W)was composed mainly of fish (55-68. ), followed by squid (32-37. ) and zooplankton (8. only in 2001). Around 60. of the fish eaten was identified as myctophids and corresponded to five genera and seven species, with higher frequency of Hygophum hygomii (24-34. ). The identification of squids consumed reached 20. in 2001 and 80. in 2002 and the only species identified was O. bartramii, which implies percentages of cannibalism of 5.6. and 25.8. each year. For the range analyzed, 141-443 mm of mantle length (ML), the consumption of fish and squid did not show any relation to the size of predator. In 2001 the...

Argentine black drum distributes mainly in shallow waters associated to estuarine areas, particularly to  Samborombon Bay where it may be detected throughout the year. Nevertheless, it can also be spotted more southwards (40°S) and at deeper waters. During summer, catches of the species in Samborombon Bay are practically negligible, probably due to movements towards shallow waters out of reach of the inshore commercial  fleet. Landings increase in autumn and show peak values in winter, coinciding with the fishing season of whitemouth croaker, Micropogonias furnieri, whose geographical distribution within the bay overlaps that of  black drum. As of 1995, landings of black drum showed increasing trends both in Argentina and Uruguay. These increments coincide...

Seasonal biomass variation and agar yield of G. salicornia (C. Ag.) Dawson from Oyster Bay, Dar es Salaam, and Chwaka Bay, Zanzibar, were determined, and some properties of the agar examined. Mean biomass and canopy cover values ranged from 21–60 g/m2 and 7– 20 %, respectively. The highest mean biomass and cover values were obtained during the SE monsoon. Agar yield varied from 13.7 to 30.2 % (dry weight) and was highest during the dry NE monsoon period. Alkali treatment generally reduced agar yield by 25–56 %. Gel strength of the agar gels ranged between 118 and 251 g/cm2 and was significantly higher during the NE monsoon period (t = 2.2; P = 0.04 and t = 8.9; P &lt;&lt; 0.05) for samples collected from Oyster Bay and Chwaka Bay respectively).

Ce travail constitue une étude comparative entre les paramètres de reproduction de Caranx crysos et ceux de Caranx rhonchus du golfe de Gabès. Afin de déterminer la maturité sexuelle, le cycle sexuel et la période de ponte, les mensurations ont été relevées sur un échantillon de C. crysos composé de 1668 individus (95mm ≤ LT≤ 416 mm) et de 1313 individus de Caranx rhonchus (10mm≤LT≤306 mm). Il ressort de cette étude que Caranx rhonchus atteint sa maturité sexuelle (LT50% femelles = 182,09 mm et LT50% mâles = 182,2 mm) à une taille inférieure à celle estimée chez Caranx crysos (LT50% femelles = 259,79 mm et LT50% mâles = 245,88 mm). En outre, les variations mensuelles du Rapport Gonado-Somatique (RGS%), montre des cycles sexuels synchrones pour les mâles et...

The analysis of DNA damage by mean of Comet or single cell gel electrophoresis (SCGE) assay has been commonly used to assess genotoxic impact in aquatic animals being able to detect exposure to low concentrations of contaminants in a wide range of species. The aims of this work were 1) to evaluate the usefulness of the Comet to detect DNA strand breakage in dolphin leukocytes, 2) to use the DNA diffusion assay to determine the amount of DNA strand breakage associated with apoptosis or necrosis, and 3) to determine the proportion of DNA strand breakage that was unrelated to apoptosis and necrosis. Significant intra-individual variation was observed in all of the estimates of DNA damage. DNA strand breakage was overestimated because a considerable amount...

RESUME Il s'agit d'un travail d'analyse de l'évolution de la pluviométrie dans la RBDS de l'origine des stations jusqu'en 1997. La RBDS située dans le site d'estuaire du Saloum est affectée par une péjoration pluviométrique qui entraîne la disparition de certaines activités agricoles (rizculture et maraîchage) et la contamination des puits par le sel et le fluor. Elle affecte principalement et durablement les ressources en eau, entraînant la dégradation des ressources végétales, la dégradation des sols visités par le phénomènes de marée qui provoquent leur salinisation et la chute des rendements des principaux systèmes productifs. Avec l'ouverture de la brèche sur la Pointe de Sangomar, le milieu est largement ouvert sur l'océan, ce qui rend difficile les...

Processing Fish: Nigeria
Provedor de dados: 20
Artisanal fishing in Africa, historically dominated by fishermen in canoes and boats who set out to sea from small coastal fishing villages in search of bonga, sardinella and other pelagic fish, has provided a nutritious source of food often cheaper than meat. As a result, fish has been consumed by large portions of the population and has become a diet staple. Today, however, some African fisheries, including the bonga (Ethmalosa fimbriata), which is widely harvested and eaten by west Africans, suffer from periods of excess harvest or glut, particularly during the peak season between November and May. Because most fishing communities do not have ice-storage facilities, the daily catch is either sold fresh or smoke-dried before it spoils....

The present paper is based on a collation of information, through both a literature review and an internet search, on North American programs that involve some kind of scientific collaboration between fishers and fisheries scientists. It identifies four basic models of such collaboration and offers examples of collaborative activities that seem to fit into each of them. The first model defers to the expertise of the scientist for all major decisions and creates a strong programmatic distinction between what is science, and shall be done by scientists, and what are other, related activities that can be carried out by others. Various kinds of tagging programs, fisher advisory boards, at-sea research collaboration and many other activities fit this model. The...

The Necessity of Optimal Perturbations
Provedor de dados: 20
Autores: DelSole, T.
An optimal perturbation is an initial condition that optimizes amplitude growth over a prescribed time in a linear system. Previous studies have argued that optimal perturbations play an important role in turbulence. Two basic questions related to this theory are whether optimal perturbations necessarily grow in all turbulent background flows, and whether the turbulent flow necessarily excites optimal perturbations at the rate required to account for the observed eddy variance. This paper shows that both questions can be answered in the affirmative for statistically steady turbulence. The argument put forward here is independent of any closure theory of turbulence. In essence, the result follows from the fact that statistical equilibrium and conservation...

Pour accomplir sa mission, le Ministère chargé de la pêche a mis en place une politique bâtie autour de la gestion durable et rationnelle des ressources halieutiques. Dans le cadre de cette politique, il a été mis en place des instruments sectoriel de gestion (permis de pêche, immatriculation des pirogues, etc.) et une réglementation à travers le cote de la pêche. Malgré la volonté affichée et les moyens déployés par l'administration des pêches, ces instruments de gestion sont difficiles à mettre en œuvre et la réglementation en vigueur est très souvent contournée par les pêcheurs artisanaux dont les aspirations et les logiques sont aux antipodes des préoccupations biologiques à long terme.

El tema de las pesquerías forma parte de la temática del medio ambiente, pero más específicamente de la del desarrollo sustentable. Esta se refiere al impacto que produce la actividad humana sobre el medio ambiente, en este caso la explotación de un recurso renovable, y a las consecuencias que ello tiene, entre otras cosas, para el desarrollo de esa actividad sostenida en el tiempo. Esta temática es compleja ya que involucra diferentes aspectos de la organización social, que se relacionan entre sí e interactúan con la naturaleza. Por ejemplo, el incremento de la capacidad pesquera mundial no puede ser entendido independientemente de la dimensión política que permite o incentiva ese desarrollo. A pesar de que el problema se ha agudizado en la última década,...

Elementos no conservativos como el SiO3, el P-PO4- y el N-NH4+ manifiestan una tendencia al incremento a medida que disminuye la salinidad presentándose correlaciones negativas significativas (α&lt;0,05), corroborando la importancia de los escurrimientos fluviales en el aporte de nutrientes. Los bajos coeficientes de correlación denotan otras fuentes de aporte. En comparación con registros anteriores se observan disminuciones en los SiO3, incrementos del P-PO4- y una variabilidad con tendencia ascendente-descendente en los compuestos nitrogenados.

Autores: Payet, R.J.
Net fishing is an important component of the artisanal fishery of the Seychelles. It is composed of beach seine, encircling and set gillnets. This report reviews net fishery and its impact on the environment and fish stocks and provides a framework for its management. There are no current management measures for the traditional net fisheries except that all nets above 50 metres requires a license with a lead seal bearing the licence number.  Certain irresponsible uses of these nets have ben acknowledged, principally the 'Met outaz' fishing strategy, incidental catch of marine mammals and the presence of commercially important juvenile fish in the beach seine fishery. SFA has addresses these issues rationally and management options are explored followed by...

Anthropogenic pressures on the coral reefs of Tanzania are high. Over-exploitation, destructive fishing practices, unplanned tourism and high sedimentation load are amongst the most evident contributing factors whilst the poor economy and increased human population density along the coast is an underlying problem. There is a clear need for alternative sources of livelihood and effective ways to manage coral reef resources sustainably. Mariculture is becoming a common component in coastal zone management in Tanzania.

The state of pollution in the Lagos lagoon was examined by a field survey of twenty-six sites (stations) in the dry and wet season in 1985. Some selected sites were further re-examined in the same period in 1986. The sediment trace metals and total hydrocarbons were analysed. The relationship between non residual and residual trace elements was examined. For both years of study, total trace metal levels (mg/kg) fell in the ranges: Cu,1.9 – 132.4, Cr, 2.9 – 167; 7.8 – 830. 6; Ph, 1.6 – 483.1 and Cd, 0.04 – 15.5. Total hydrocarbon concentrations in 1985 ranged from 0.25 to 2766.27 mg/g with high concentrations in muddy and sandy sediments. The results show marked variations and non – uniform distribution from one season to another. With few exceptions,...

Tree and pneumatophore height and density of Avicennia marina were measured along a point -intersection/band transect at Nabq, Red Sea, to establish possible zonation patterns amongst these mangrove characteristics. There was a significant increase in pneumatophore height and density landwards to seawards. Tree density decreased significantly down the transect. Graphical analysis showed an increase in tree height followed by a decrease at the seaward edge. Investigation of a theoretical increase in productivity (biomass) down the shore by leaf index calculation (leaf index = average leaf area x number of leaves per station) was inconclusive from data obtained.

The effect of pollution on coral recruitment has been insufficiently studied. This research deals with coral recruitment in coastal areas and aimed to determine the variations of density and dominant species of corals recruits in sites at different distances from pollution sources. The composition and structure of stony coral (scleractinian and milleporids) recruit associations were characterized in the fringing reef of Western Havana, Cuba. This reef is influenced by urban pollution from the Almendares River and a sewage outlet located at its mouth. Four sites were sampled on the upper fore reef escarpment at 10m deep every three months between July 2007 and May 2008. A 25cm side quadrat was used to determine the density and taxonomic composition of...

La détérioration de la qualité des eaux de la lagune de Boughrara, conséquence de divers apports polluants et d’échanges d’eaux limités avec la mer, s’est traduite  par un accroissement sévère de l’eutrophisation du milieu se manifestant notamment par d’importantes proliférations microalgales. L’analyse de l’évolution de l’ensemble des groupes phytoplanctoniques a montré que les périodes de forte biomasse algale sont caractérisées par des développements  monospécifiques. L’importance relative croissante de la classe des dinoflagellés se manifestent par un net accroissement du rapport dinoflagellés / diatomées.

Both mackerel mean biomass and mean fishing effort in Buenos Aires (Argentina) shelf during the period 1990-91/1994-95 were estimated. Those values were 85,792 t and 42,051 minutes, respectively. However, the best economic profit from the fishery (about $15,390,036)($1=U$S1) was estimated to take place at 28,000 minutes. It was observed a waste in fishing effort of the commercial fleet related with sea surface temperatures of 19°C or more. Moreover, adult mackerel find better trophic conditions on the continental shelf (depth 50m), while larvae originated from massive spawning in late November-early December, i.e., during the main fishing season, find their optimum at lower depths. Mackerel shoals enter and leave fishing grounds in a counterclockwise way...

Autores: Giménez, E.
The red grouper fishery is in its decline phase presenting an average annual catch of 8191 t during the 1999 to 2003 period. Through these years Cuban fleet has reduced its fishing area toward the oriental region of the Campeche Bank while the artisanal fleet extended, increasing the overlap of sizes catched by the arisanal-industrial and artisanal-cuban fleets. The size composition of the catch shows that most of the fishes are captured before first maturation size. First catch age is 2 years, and complete fishery recruitment is at age 3 (age of first maturation), this being a factor against fishing sustainability and forcing adoption of management strategies. The natural mortality is calculated (M) for the each age in the fishery by the function Y =...

Effect of Fouling on Feeding, Oxygen Consumption and Waste Excretion of Pearl Oyster Pinctada martensii in Daya Bay Cultivation.
Provedor de dados: 20
Autores: Su, Zhenxia; Yan, Yan; Huang, Liangmin.
Biofouling is a particular problem in the pearl oyster culture. It may reduce the growth and survival rates of the cultured species. Foulers are often themselves filter feeders, and are therefore potential competitors for food resource with the cultured species. Fouling organisms may also reduce the oxygen supply. A study was conducted to measure the impact of foulers on feeding, oxygen consumption, and waste excretion. POM, ammonia, phosphate and oxygen concentration were measured in various treatments (cultured species，foulers). This study showed that fouling organisms had significant effect on food uptake, oxygen consumption and waste excretion. The clearance rate, ammonia and phosphate release rate, oxygen consumption rate of the fouled pearl oyster...

A non-parametric indicator Kriging method for generating coastal sediment type map.
Provedor de dados: 20
Autores: Liu, Fucheng; Peng, Jun; Zhang, Cunyong.
Coastal sediment type map has been widely used in marine economic and engineering activities, but the traditional mapping methods had some limitations due to their intrinsic assumption or subjectivity. In this paper, a non-parametric indicator Kriging method has been proposed for generating coastal sediment map. The method can effectively avoid mapping subjectivity, has no special requirements for the sample data to meet second-order stationary or normal distribution, and can also provide useful information on the quantitative evaluation of mapping uncertainty. The application of the method in the southern sea area of Lianyungang showed that much more convincing mapping results could be obtained compared with the traditional methods such as IDW, Kriging...

La présente étude a pour objectif la mise en place d’un système de modélisation numérique de la dynamique marine près des côtes tunisiennes. Pour cela on imbrique un modèle de circulation de l’eau près des côtes tunisiennes dans un modèle de circulation générale de la mer Méditerranée. La grille du modèle des côtes tunisiennes comporte la possibilité d’augmenter la résolution dans un domaine ciblé. Les conditions initiales pour ce modèle étiré sont obtenues par interpolation des états simulés par le modèle côtier à résolution constante. Vu sa résolution plus élevée, le modèle à grille étirée nécessite un long temps de calcul. Cependant les tests effectués avec ce modèle montrent que des simulations de 20 jours suffisent pour atteindre un équilibre...

Autores: Paula, J.; Paula e Silva, R.; Hernroth, L.; Guissamulo, A.T.; Bandeira, S.O.; Gove, D.Z.; Macia, A.
This synopsis describes the development of marine biological research, including fisheries, in Mozambique. With around 3000 km of coastline, the living resources of the sea playa major role in the Mozambican society, mainly as a source of protein and income for the population, and of foreign revenue through exports. In the first years, after independence, in 1975, research activities in marine sciences were limited and mainly concentrated to fisheries through cooperation with Norway and the Soviet Union. A new era for biology started in 1985 when the Faculty of Biology at Universidade Eduardo Mondlane was re-opened. A 5yr curriculum towards a licentiate degree was introduced with a strong marine profile. Since the 1990s, a very dynamic de-velopment in...

Water, Salt and Stoichiometrically linked nutrient budget for Chwaka Bay, Tanzania
Provedor de dados: 20
Autores: Ngusaru, A.S.; Mohammed, M.S.
The water and salt balance at Chwaka Bay in Zanzibar, Tanzania suggests that in order to balance the inflow and outflow of water, there must be a net flux of water from the bay to the open ocean during both the dry and wet seasons. The corresponding salt residual fluxes indicate advective salt export. However, exchange between the bay water with the open ocean replaces this exported salt via mixing. The freshwater residence times at Chwaka Bay are 24 days for dry and 37 days for wet season. The budgets for non-conservative materials indicate a net dissolved inorganic phosphorous (DIP) and dissolved inorganic nitrogen (DIN) flux from the bay to the ocean during wet season. The calculated DIPsyst and DINsyst suggest that the bay acts as a DIP and DIN source...

Los resultados de este estudio permitieron conocer que la temperatura de máxima transición endotérmica correspondiente a la desnaturalización de las proteínas presentes en el músculo del bonito  (Katsuwonus pelamis) oscilaron alrededor de los 75 ºC, independientemente de la talla. A partir de esta temperatura se ensayaron dos métodos de cocción para el bonito antes de su enlatado; cocción en balsinas con agua hirviendo y cocción a vapor. Los resultados indicaron que la cocción en balsina posibilitó obtener mayores rendimientos (83,15 %) que en el horno de vapor (76,29 %). Resultados similares se obtuvieron durante la limpieza del filete cocido (47,62 % para la balsina y 34,69 % para el horno), debido a la menor deshidratación de la carne del pescado cocido...

The number of purse seiners active in the Western Indian Ocean remained high during the first quarter of 1989, ranging from 49 in January to 48 in March.  This represents a significant increase in the number of vessels over the same period last year when an average of 36 vessels was in operation. Excellent fishing results prevailed throughout the first quarter of this year.  Catch rates reached a record high, for that period, of 26 MT/day compared to 18 MT/day for the same period last year.  The proportion of yellow fin in the catch dropped from 58% in January to 36% in March, with a corresponding increase in the proportion of skipjack from 40% to 63%.  This is unusual for this time of the year, when yellow fin is the predominant species in the catch. The...

The biogeogeographical distribution of Platasterias latiradiata Gray, considered a "living fossil" is extended to Ecuador, which has been founded close to the coast of Mexico and Central America. A map gives the new distribution, as well as a comparative study of the external morphology in a similar way as the reports and contributions of Caso, M. (1961, 1976). It is also included a table with measurements of several parts of the body, considered of taxonomic importance and pictures, showing predation on the gastropod, Olivella semistriata like one of its common food of preference.

Estudio de la edad y crecimiento del recurso merluza común (Merluccius hubbsi) durante el período 1968-1970; determinación de las fluctuaciones del recurso
Provedor de dados: 20
Autores: Villarino, M.F.
La merluza común (Merluccius hubbsi) es uno de los más importantes recursos pesqueros del Mar Argentino. Constituye aproximadamente el 68 por ciento de las capturas desembarcadas, según lo indicado por las estadísticas oficiales (Boletín Oficial, Subsecretaría de Pesca, 1988). Su explotación ha mantenido una tendencia creciente a partir de 1974, como consecuencia del incremento de las capturas de Argentina y el plan de desarrollo pesquero implementado por Uruguay. Las capturas de 1978 y 1979 superaron ampliamente el valor del rendimiento máximo sostenible, estimado en 344.000 toneladas (Verazay y Otero, 1986), y se mantienen próximas al mismo a partir del último año mencionado.Como resultado de esta explotación el recurso pesquero se redujo aproximadamente...

Quelques aspects du beach-rock dans le golfe du Bénin : le cas du Togo
Provedor de dados: 20
Autores: Blivi, Adoté.
Les dalles de beach-rock naissent dans les dépôts sédimentaires marins d'âge Holocène et caractérisent les anciennes lignes de rivage. Du fait de l'érosion des plages actuelles qui les recouvraient, elles affleurent en différents points de la côte du golfe du Bénin, jouant par endroits un rôle temporaire de protection naturelle et constituant un handicap pour la pêche traditionnelle. Sur la côte togolaise , elles figurent à différentes attitudes ; dans certaines segments de côte, elles atténuent l'énergie des vagues. Ailleurs elles sont en continuité topographique avec la plage aérienne. Une série de travaux portant d'une part sur les formes et les structures globales a conduit à la connaissance de ces anciennes plages cimentées et d'autre part sur la...

Modélisation de la dispersion du phosphogypse dans le golfe de Gabès
Provedor de dados: 20
Autores: Bejaoui, B.; Raïs, S.; Koutitonsky, V.
This work concerns the modeling of the phosphogypsum dispersion emitted by the chemical industries in the gulf of Gabès. The CORMIX model based on the dimensional analysis theory is used for this study. An analysis of the sensitivity of the model parameters was initially made; eight simulations were then carried out to determine the space extent of pollution on the level of the gulf. For each condition of tide, we carried out four simulations, two concerns the high tide and two concerns the low tide. Simulations showed that pollution by phosphogypsum is spread out in space over a surface of about 60 km2.

In the late 1960s IODE started the system of the National Oceanographic Programmes (NOPs) and Cruise Summary Reports (CSRs, formerly ROSCOPs) as a way to share information on planned research cruises as well as to report on the results of research cruises. For many years the NOP information was managed by the IODE Secretariat. However, at IODE-XV (1995) an offer was made by the University of Delaware to take on this task as part of OCEANIC (www.cms.udel.edu). The IODE Committee accepted this kind offer and Oceanic managed the service for well over ten years. At IODE-XVI, IODE decided to cease the mailing of paper copies of NOPs by the Secretariat, requested NODCs to mail NOPs directly to OCEANIC, and recommended that NOP information be made available...

The coastal zone and oceanic problems of Sub-Saharan Africa
Provedor de dados: 20
Autores: Ibe, A.C.
The coastal zone and oceans surrounding Sub-Saharan Africa, with their vast resources of food, energy, and minerals, not only are composed of various fragile ecosystems, but are scenes of a variety of often conflicting uses. At present, the uncontrolled development of the coastal zone and ocean and the almost haphazard exploitation of their natural resources threaten to turn the promise of economic prosperity into an environmental nightmare that portends great dangers for present and future generations. There is the urgent need to put in place national management policies that address the environmental controls and procedures to be applied in pursuit of economic development. However, the oceans have no physical boundaries corresponding to national...

Economics of Coral Reef Restoration
Provedor de dados: 20
Autores: Spurgeon, J.P.G.; Lindahl, U.
This chapter provides an introduction to the economics of coral reef restoration. A comparison of coral restoration schemes from four countries indicates that costs can vary from some US$ 13,000 per ha to over a hundred million US$ per ha. However, it also reveals that cost estimates in the literature are not readily comparable, and that many cost components of restoration are ignored. Little work has been conducted into the potential benefits of coral restoration. This issue is briefly considered with reference to the case studies. The chapter suggests that a benefit–cost analysis approach should be used more often to help assess the justification for coral reef restoration and to improve the efficiency of any such expenditure. It is clear that a greater...

Exploitation et optimisation de la production des cystes du crustacé "Artemia tunisiana" (bowen et sterling, 1978) dans la saline de Sfax

Autores: Aloui, N.; Amorri, M.
La saline de Sfax constitue le meilleur site pour l’exploitation et la production d’Artemia en Tunisie. La production de cystes est exploitée chaque année pour être utilisée dans l’alimentation des larves de poissons. Cette production est estimée à 30 kg de cystes poids sec. Toutefois, lors de nos campagnes de récolte, nous avons enregistré de grandes pertes de cystes occasionnées par les vents emportant les cystes qui seront mélangés avec le sable.    Afin de minimiser les pertes et optimiser la production naturelle de la saline, nous avons jugé utile, d’installer des barrages dans les coins des bassins à Artemia pour s’opposer à l’action du vent. Par ailleurs, nous avons fait un suivi mensuel de l’abondance des cystes récoltés et de quelques paramètres...

While terrestrial parks and reserves have existed in Tanzania since colonial times, marine protected areas are a much newer endeavor in natural resource conservation. As the importance of marine conservation came to the international forefront in the 1990s, Tanzania experienced a rapid establishment and expansion of marine parks and protected areas. These efforts were indeed crucial to protecting the country’s marine resource base, but they also had significant implications for the lives and fishing patterns of local artisanal fishermen. Terrestrial protected areas in Tanzania have historically been riddled with conflict and local contestation, bringing about numerous debates on the best ways to involve rural residents in conservation planning efforts to...

Autores: Codignotto, J.
In Argentine coastal areas, geomorphological changes are directly related to relative continental uplifts and falls and to seaward and landward displacement of the coastline. Accretional and erosional phenomena are produced by displacement of the coastline in horizontal way. The resultant structures can be represented in two principal sectors. Backward motion or retrogradation of about 15 km were estimated for the Strait of Magellan, over an area of 500 km 2.Otherwise, large accretional phenomena were recognized in the north,with a 60 km seaward displacement, equivalent to 4,000 km2 in the last7.000 years. Variation in tidal regime and amplitude is reflected in the coincidence of the boundary between accretion and erosional sectors. Two principal nearshore...

Evaluación de diferentes niveles de inclusión de ensilado químico de pescado en dietas para Clarias gariepinus(Burchell, 1822)
Provedor de dados: 20
Autores: Llanes Iglesias, J.; Toledo Pérez, J.; Lazo de la Vega y Valdez, J.
The objective of this study was to evaluate five half-moist diets with graded levels of chemical fish silage (40, 50, 60, 70 and 80 %) prepared with 2 % sulfuric acid 98 % (weigth/volumen), as a unique animal protein source. They were compared with a commercial food (20 % of fish meal), Clarias gariepinus feeding during 60 days. The experimental design was completely randomized and the statistical analysis of the results was done through analysis of variance and the results were compared through the Duncan test at 5 %. The results showed that indicators such as: growth, feed utilization and survival rate did not differ significantly (p &gt; 0,05) between experiment diets, representing between $188,00 and 302, 00 USD/t saving at fingerling.

Management of shark fisheries in Seychelles
Provedor de dados: 20
Autores: Nageon de Lestang, J.
Shark species, both oceanic and coastal, are very common to Seychelle waters. In the past, however, the demand for shark and shark products has always been very erratic. The ever-increasing international concern for the species and potential conflicts between fishermen and conservation groups has highlighted the issue. In the Seychelles, the shark are caught by gillnets in inshore waters and by hook-and-line and purse seine offshore. Until very recently there were no regulations controlling the shark fishery, but, partly in response to initiatives by a local conservation group, fishing for sharks with nets has been banned since 1 August 1998. A review is provided of the present situation of the fishery whilst underscoring the difficulties of formulating a...

The Bay of Havana is one of more polluted ecosystems in our country, because the hydrocarbons concentration in the water and sediment is very high. The bioremediation is a good technique for the elimination of the contaminant. In the Center of Marine Bioproduct we have developed some different bioproduct based on hydrocarbons degrading marine bacteria for the eliminatation the hydrocarbons in sea water. The bioproduct called BIOIL-FC has been used with excellent results in the mitigation of different oil spill in cuban ecosystems. In this work were compared the effectiveness of biodegradation between bioaugmentation with BIOIL-FC and isolated microorganisms from sediment of the bay and the biostimulation with inorganic nitrogen and phosphorus.

Aquaculture Training for Kenyan Fisheries Officers and University Students
Provedor de dados: 20
Lack of technical training has been cited as a major reason for the low output of fish ponds in Kenya. The lack was observed at all levels, from the lowest level extension agent through university levels. The training program undertaken by the Africa Project in Kenya seeks to improve training and to provide a cadre of trainers who have extensive practical fish production experience. This year the Africa Project has begun scholarship support for two MS students, one at Moi University’s Chepkoilel Campus, Eldoret, Kenya, and the other at Auburn University, Auburn, Alabama. Small stipends for student research conducted at Sagana Fish Farm have allowed undergraduate as well as graduate-level university students to remain longer to complete projects and gain...

Relatório do levantamento hidrográfico do Porto de Quelimane.
Provedor de dados: 20
O canal de acesso ao porto de Quelimane, tem sofrido grandes alterações com o tempo, segundo consultas efectuadas a dados de cartas antigas (Portuguesas), e os levantamentos anteriores. As zonas muito críticas são: na barra, entre boia 7 e 4 e na bacia de manobra, que está sempre a sofrer assoreamento, e consequentemente o canal de entrada naquele ponto muda constantemente de tempo em tempo, infelizmente ainda não se conhece o tempo de mudança, mas prevê-se que seja cíclica, embora não com muita exactidão. Face a esta realidade, foi realizado o levantamento com vista a identificar um novo e melhor canal, a sua sonda mínima, e recolocar bóias que sinalizem tal canal. Também constituiu objecto do levantamento averiguar o assoreamento de todo o canal, e no...

Autores: Garciarena, A.D.; Buratti, C.C.
The fishing activity on Argentine anchovy Northern stock (34º S-41º S) during the 1993-2011 period was studied (SW Atlantic Ocean, Argentine Sea). The basic data derived from the commercial fleet catch records. Annual landings reached a minimum of 5,900 t in 1999 and a maximum of 36,300 t in 2004. The largest catches, performed by the offshore ice chilling fleet, averaged 11,800 t. As of 2003 it was observed an increase in the coastal ships share and a decrease in that of the inshore fleet that in 2004-2011 represented less than 3% of total landings. The major activity, developed between 37º S-41º S in the August-November period, had Mar del Plata as the main port of landing. The average catch per trip and the mean HP of ships, that as of 1999 increased in...

Abundancia relativa y rendimiento máximo sostenible de la merluza común (Merluccius hubbsi)
Provedor de dados: 20
Autores: Otero, H.O.
The statistics provided by the Argentinean Fishing Vessel and the biological data collected by scientist in the last eleven years, allow us to estimate different aspects of the population dynamics of the common hake (Merluccius hubbsi). This work deals with the relative abundance and the maximal sustainable yield of this species, considering the bonaerense stock of the Southewest Atlantic. Analyzing the effective fishing density, concluding remarks can be made. The high catches of 1967 (more than 600.000 tons.)made by the Russian Fleet, affected the fishing density in 1968. Since 1969, the resource recovered the high density level as a consequence of a decrease in the catches and in the fishing effort, but vulnerability of the stock is shown.

Dynamique sédimentaire et répartition granulométrique des sédiments de surface dans la frange littorale Ras Taguermess-Ras Marmour (golfe de Gabès)
Provedor de dados: 20
Autores: Brahim., M.; Abdelfattah., A.
Les analyses granulométriques des sédiments superficiels de la zone côtière située entre Ras Taguermess et Ras Marmours montrent que les petits fonds (-2 à -10 m) sont couverts par des sables fins aux sables grossiers (la moyenne est entre 0,39  et 3,34 ), généralement mal à très mal classés. Cependant, le haut de plage situé entre Ras Taguermess et Ras Marmour est couvert essentiellement par des sables fins et des sables moyens (la moyenne est entre 1,082 et 2,823 ). La répartition spatiale des sables ne montre pas un grano-classement décroissant ou croissant des sédiments de la côte vers le large. Cette distribution est due à l‘existence d’une énergie importante où la houle joue le rôle essentiel sur leur répartition. L’étude granulométrique montre aussi...

Autores: Reyes-F., J.; Navas-S., G.R.
A cheap and versatile methodology  to get digital images of dry and wet preserved organisms, using a flat bed scanner, is presented. To obtain the images of  wet specimens, a shallow  pool was glued on top of the scanner glass. The pool is filled with water or alcohol and the organisms are immersed and their structures expanded. The best images were obtained with organisms between 1.5 and 15 cm in length. The depth of field was limited to 1.2 cm. These images are also useful for taxonomical research without the need of manipulating the organisms;  they can be used too, to compare with better accuracy certain structures between different specimens.

What Does the Future Hold for Malagasy Coastal Communities?
Provedor de dados: 20
Autores: Randrianasoavina, F.
Traditional fisheries in Madagascar provide the main source of livelihood for over 100,000 fishermen from 1250 communities along 5,000 kms of coast. The fishery provides 50% of the Malagasy fish catch and supplies 70% of the fish locally consumed. Despite this, the sector is not recognised officially, and is marginalised from mainstream national economic development. Since 1995 a group of Malagasy NGOs, supported by European NGOs, have been drawing public attention – both locally and internationally – to this situation. Over the last 6 years they have carried out a number of programmes both locally and internationally. These have involved studying and documenting the traditional sector, organising formal meetings between representatives from traditional...

Assessment of Land-based Sources and Activities. Affecting the Marine Environment
Provedor de dados: 20
The Red Sea and Gulf of Aden (Figure 1.1) constitute a unique ecosystem with high biological diversity. Their natural resources provide a substantial economic support for the region: in addition to the fishery industry, which has ensured food security to many people of the region and created jobs for others, tourism is an ever growing and increasingly important industry for commerce and other economic activities. Hence, the marine environment should be well protected from the adverse impacts of pollution to ensure the sustainable use of its resources and good health of its users. Continuous degradation of the marine environment poses a threat to public health through the contamination of seafood, direct contact and digestion of polluted water. Damage to...

Earthworm and maggots meals as potential fishmeal replacement
Provedor de dados: 20
Autores: Yaqub, H.B.
Three meals were formulated from the earthworm (Endrilus eugineae) and maggot (Musca domestica) and fish (Engraulis encrosicolus). These meals were evaluated as a potential replacement for fishmeal. This is because fishmeal could be very expensive at times. The three meals were used in feeding the catfish (Heterobranchus isopterus) fry for 30 days.   The study was conducted in 1991 at the Institute of Renewable Natural Resources Farm, University of Science and Technology.  Two replicates were done using four hapas in each replicate. Each hapa was stocked with 50 fry and fed. Those in the fourth hapa were not fed to ascertain the effect of supplementary feeding on the growth of the fish. Weight increment was found to be less in the fourth hapa than the...

Trinidad and Tobago has declared various maritime zones consistent with the provisions of the 1982 United Nations Convention on the Law of the Sea. The uses of these zones are extensive ranging from trade-related to recreational activities. Monitoring such a wide range of users is a challenge for many States and requires a comprehensive regulatory regime capable of empowering the relevant authorities with the means for its effective implementation. While the domestic legal and institutional framework governing marine environmental protection and conservation lags far behind that of the international arena, thereby rendering many of the applicable international laws non-operational, there are various institutions that are involved in protecting and...

Group types and surface activities of humpback whales breeding in S. Tomé and Príncipe, Gulf of Guinea
Provedor de dados: 20
Autores: Brito, C.; Carvalho, I.; Reiner, F.
S. Tomé and Príncipe archipelago has been reported as a possible breeding ground for humpback whales (Megaptera novaeangliae) since the whaling period. More recently, the sightings of humpbacks whales have become more frequent off the S. Tomé Island which may indicate a recovery of the populations or the whales returning to a former concentration area of the Southern Hemisphere population. Our objective was to study the occurrence of humpback whales group types and surface activities in this area. Between July 2002 and January 2003, a total of 110 boat-based surveys were conducted around the S. Tomé Island and Rolas Island. When we sighted the animals, recordings of GPS positions, group size, group composition and activity were made. Single whales and...

The effect of turbid inflows into Winam Gulf, Lake Victoria: a 3D modeling study with ELCOM-CAEDYM
Provedor de dados: 20
Autores: Njuguna, H.; Romero, J.R.; Khisa, P.
The catchment of Winam Gulf in Kenya supports a population of 4.5 million inhabitants. Much of the population practices subsistence agriculture in the catchment that has led to high rates of sediment erosion and ultimately highly turbid rivers. Hence, every year during the two equatorial wet seasons, large quantities of catchment sediments are deposited into Winam Gulf. In Apr.-May 2005 an intensive field investigation was undertaken to determine the exchange dynamics between the northeastern offshore waters of Lake Victoria and Winam Gulf through Rusinga Channel. One of the outcomes of this scientific study was the validation of ELCOM (Estuary, Lake and Coastal Ocean Model), a three-dimensional (3D) hydrodynamics model, over Rusinga Channel and Winam...

Renewable natural resources (RNR) are a major source of socio-economic development potential in all developing countries, if they can be conserved, developed and sustainably exploited. For strategic conservation and sustainable exploitation strategies to be implemented, a knowledge of biodiversity at various levels within these RNR has to be investigated and documented in an internationally accepted manner, and preferably as close as possible to the habitat of the resources. However, human and material resources available in developing countries are currently neither sufficiently trained nor sufficient to undertake the appropriate studies. Meanwhile, various forces continue to deplete RNR and their inherent biodiversity. An attractive approach towards...

Autores: Mailu, G.M.; Kiai, S.P.M.
Kenya has a growing population projected to increase to 34 million people by the turn of the century. Though the country is undergoing industrial transformation, agriculture remains the mainstay of the economy. The country has an area of about 587 900 km2 of which 576 000 km2 is land surface. 88% of the land surface is classified as arid and semi-arid lands (ASALs) and the remaining 12% forms the medium and high agricultural potential land. This classification is based mainly on the moisture index as indicated by average annual rainfall and evapotranspiration. The Great Rift Valley running north/south influences and determines the drainage pattern so that from the flanks of the Rift Valley, water flows westwards to Lake Victoria and eastwards to the Indian...

The role of wetlands in lake ecological functions and sustainable livelihoods in lake environment: A case study on cross border Lake Jipe - Kenya/Tanzania
Provedor de dados: 20
Autores: Ndetei, Robert.
Wetlands are highly productive ecosystems. Their values and functions support other ecosystems and are significant to economic development. They once covered large areas of the world and are now among the rarest and most at-risk ecosystems. They are highly valued for their recreational, educational, scientific, aesthetic, spiritual and cultural values; and form an important component of lakes that provide critical functions influencing lake ecological functions. Despite the important roles in sustaining vibrant lake ecology, supporting economic development and elevating poverty, almost all wetlands in the world are threatened by diverse human induced factors. Lake Jipe striding across the Kenya-Tanzania international boundary is an important ecosystem to...

Assessment of the extent of damage, socio-economic effects, mitigation and recovery in Tanzania: Proposal
Provedor de dados: 20
Autores: Muhando, C.A.
Coral reefs play a crucial role to the well-being of coastal communities in Tanzania. Coastal fisheries, ecotourism and coastal land protection are, to some extent, sustained by coral reefs. A variety of fish species, spiny lobsters, octopus, sea cucumbers, clams, oysters and turtles form the basis of harvestable reef resources. More than 30% of marine fish landings are harvested on or adjacent to coral reef environment. Coral reefs also support offshore fisheries by providing feeding and nursery grounds for some oceanic (pelagic) fish stocks. Tourism based on coral reef ecosystems is peaking up, creating new opportunities for employment and substantial amounts of income for the people of Tanzania.

An Ocean Theme for the IGOS Partnership
Provedor de dados: 20
The Integrated Global Observing Strategy Partnership (IGOS-P) established, in 1999, a thematic approach to the implementation of the IGOS. Recognising that other themes will emerge, the “Ocean Theme” was chosen to be the “pathfinder” in this approach and an Ocean Theme Team was assembled to formulate guidance. One goal of the Ocean Theme Team is to consider and study the full range of current and planned observations, while identifying potential gaps in future observations that might compromise ocean observational records. This document presents a proposed set of long-term ocean observations and identifies a number of challenges for the improvement of knowledge about both the oceans and observing techniques. The overall strategy is to create an observing...

Alexandria lies on the Mediterranean coast at the western edge of the Nile Delta. It was founded in 331 BC and over the next three centuries became a centre of trade and scholarship. Three major archaeological sites from different eras remain: the 15th century Qait Bey Citadel, the submerged remains of Ptolemaic Royal Quarters and underwater ruins of the ancient lighthouse, the Pharos. An international workshop on Submarine Archaeology and Coastal Management (known as ‘SARCOM’) was held in Alexandria in April 1997, organized by the University of Alexandria, the Supreme Council of Antiquities and the United Nations Educational, Scientific and Cultural Organization. The workshop followed a series of recent archaeological discoveries in Alexandria’s Eastern...

Comparative study on octopus vulgaris (cuvier, 1797) from the mediterranean and red sea coasts of egypt
Provedor de dados: 20
Autores: Gabr, H.R.; Riad, R.
Specimens from common octopus, Octopus vulgaris captured from the Red Sea and Mediterranean Sea showed significant differences in four of seven morphometric measurements .These differences are sufficient to recognize the populations of this species in the two habitats. The computed length-Wight relationship and condition factor for common octopus in both areas showed that representatives of this species from the Red Sea are heavier than those captured from the Mediterranean Sea for the same length group. Moreover, the natural mortality coefficient of Mediterranean representatives was comparatively higher than for the Red Sea octopus. This shows that the environmental conditions in the Red Sea are more suitable for O. vulgaris than in the Mediterranean Sea.

Abundance and Population Structure of the Blacklip Pearl Oyster, Pinctada margaritifera l. 1758 (Bivalvia: Pteriidae), in Coastal Kenya
Provedor de dados: 20
Autores: Kimani, E.N.; Mavuti, K.M.
Pearl oysters are an important marine resource within the Indo-Pacific oceans. They are widely cultured for the production of black pearls, their flesh is eaten, and their shell, known as mother-of-pearl (MOP) is used in the ornament and button industry. The blacklip pearl oyster, Pinctada argaritifera L., has been harvested from East Africa for MOP for decades. A survey within nearshore habitats in Kenya showed that Pinctada margaritifera is widely distributed in shallow lagoons, bays and channels. Other oyster species found during the survey were the wing oyster, Pteria penguin, occurring in deep channels in Shimoni and Mombasa, and Pt. chinensis, within lagoons and channels in Malindi, Mombasa and Shimoni. Pinctada margaritifera was most abundant in...

African Aquaculture: A Regional Summary with Emphasis on Sub-Saharan Africa
Provedor de dados: 20
Autores: Moehl, J.; Machena, C.
The African Region consists of 48 countries and five island nations, most of which are practising some form of aquaculture, often at a very low level. Over half the countries report producing less than 100 mt annually. The largest producer is Nigeria (17 700 mt) followed by Madagascar (5 100 mt) and Zambia (4 700 mt). The 1997 combined aquaculture production of the region was 40 300 mt. Aquaculture is estimated to be 95 percent small scale, with fish ponds integrated into the mosaic of agricultural activities. Mean yield is approximated as 500 kg/ha/yr, although the range is wide, from less than a hundred to more than 10 000 kg/ha/yr. A typical scenario would be a 300 m2 pond producing 15 kg a year relying on family labour and on-farm inputs. There is...

This study was based on four seasonal cruises during 1984 and 1985.  It revealed a thermo-haline frontal system formed by the advection of the Coastal Water mass flowing in two branches, one running towards the coast and the other mid-shelf directed. The thermocline developed between late spring and autumn results in a low inorganic nutrient concentration in the upper layer. Nonetheless in winter, a vertical homogeneity and high nutrient concentration were observed.  Phytoplankton development presented a typical temperate-seas annual cycle. In winter, reduced populations were dominated by diatoms. The highest biomass concentration in the cycle coincided with the spring blooming, to which Thalassio sira anguste-lineata,Alexandrium tamarense, Heterocapsa...

En el Ecuador se utiliza el cambio de color en la piel del dorado amarillo a blanco como indicador de la calidad. Se investigó este cambio en relación a la formación de histamina bajo varias condiciones. Luego de este estudio se concluyó que, en combinación a otros parámetros como olor y textura, el color de la piel puede ser útil para distinguir pescado de buena calidad (grado A) y pescado de calidad inferior (grado B). Sin embargo existen condiciones bajo las cuales es posible tener dorado no apto para consumo humano con piel amarilla y por eso siempre es recomendable revisar todas las características sensoriales en la evaluación de calidad. Este cambio de color no hace posible la distinción entre dorado con niveles significativos de histamina. Solamente...

Interest in natural products as a source for innovation in drug discovery and agrochemicals is still growing worldwide.  Natural products, whose immense diversity has been appreciated for many years, may become in a rich source of  novel chemical structures. Our country is a rich source of both biological and chemical diversity which may be useful  as a source of novel chemical structures. Even when natural products have been used as medicinal agents for many  years in Cuba, their use as agrochemicals are still limited. Thus, the present review focuses on recent advances in  the studies on natural products performed by the “Centro de Estudios de Productos Naturales, CEPN” during the past  ten years, highlighting on those with potential use as biomedical...

The fauna of the Argentine (SW Atlantic Ocean) shelf allows to distinguish two biogeographic provinces: the Argentine and the Magellanic that are part of the Subtropical and Subantarctic Regions. The former extends from 30° S-32° S to 41° S-44° S and from the coast to the 82-95 m isobath, between 35° S-39° S, to 70 m depth in the north Patagonia. The latter extends from the Valdés Peninsula to the southern extreme and from 43° S northward, east area of the Argentine Province. The different physiographic characteristics allow to distinguish movable sandy bottoms in the Argentine Province and in the Magellanic gravel bottoms where large algae grow. The climatic differences explain the prevalence of northern winds in the first, where warm and temperate-cold...

The present report reviews the spiny lobster fishery on the Mahe Plateau for the 2001/2002 fishing season. The monitoring programme, set up in 1992, was continued this season to collect more information on the spiny lobster stock in order to improve and maintain proper management of this resource around the Mahe Plateau.  For the 2001/2002 lobster fishing season, a total of 40 licenses were issued namely twenty seven on Mahe, five on Praslin and eight on La Digue. Similar to previous seasons, the most frequently used lobster fishing technique was snorkelling which involved 32 fishing units, whilst only four units used the trap method and one used both snorkelling and trap.  For this three-month fishing season, a total of 5.5 tonnes of spiny lobsters were...

Status Of Coral Reefs In Eastern Africa: Kenya, Tanzania, Mozambique And South Africa
Provedor de dados: 20
Autores: Obura, D.
Eastern African coral reefs were severely impacted by the El Niño Southern Oscillation of 1997-98, with bleaching and mortality levels varying from &lt;1% in South Africa to 80% and greater on reefs in northern Tanzania and Kenya. Recovery of affected reefs to 2002 has been poor to moderate, and patchy. Reefs strongly impacted by the El Niño that had high coral diversity and cover have recovered to less than one quarter of pre-bleaching coral cover. However, some high diversity reefs that escaped the bleaching impacts have remained healthy, with high coral cover and diversity. Degraded reefs outside Marine Protected Areas (MPAs) that were severely damaged by the El Niño have generally recovered to 50-100% of pre-bleaching coral cover. Recruitment of corals...

Le developpement de la peche thoniere dans l'Ocean Indien face aux ressources

Autores: Hallier, J.P.; Michaud, P.
Since 1983, tuna purse seine fishery has increased rapidly in the Indian Ocean. This fishery, being mostly based in Seychelles, represents an excellent opportunity to this country. However, it is essential that a good management strategy be adopted in order to ensure the rational exploitation of the resources. Since this fishery is in its early stage of development, it is not yet possible to obtain an accurate assessment of the stocks based on usual stock assessment methods. Nevertheless, from existing knowledge on the Indian and Atlantic oceans, a preliminary analysis of the resources is attempted. Of the two stocks studied, the skipjack, known as an opportunist species, can support a higher exploitation rate than the yellowfin. It would seem that catches...

The Characteristics of Signal versus Noise SST Variability in the North Pacific and the Tropical Pacific Ocean
Provedor de dados: 20
Autores: Yeh, S.W.; Kirtman, B.P.
Total SST in a coupled GCM is diagnosed by separating the variability into signal variance and noise variance. The signal and the noise is calculated from multi-decadal simulations from the COLA anomaly coupled GCM and the interactive ensemble model by assuming both simulations have a similar signal variance. The interactive ensemble model is a new coupling strategy that is designed to increase signal to noise ratio by using an ensemble of atmospheric realizations coupled to a single ocean model. The procedure for separating the signal and the noise variability presented here does not rely on any ad hoc temporal or spatial filter. Based on these simulations, we find that the signal versus the noise of SST variability in the North Pacific is significantly...

Autores: Dirmeyer, P.A.
Skill in ensemble-mean dynamical seasonal climate hindcasts with a coupled land-atmosphere model and specified observed sea surface temperature is compared to that for long multi-decade integrations of the same model where the initial conditions are far removed from the seasons of validation. The evaluations are performed for surface temperature and compared among all seasons. Skill is found to be higher in the seasonal simulations than the multi-decadal integrations except during boreal winter. The higher skill is prominent even beyond the first month when the direct influence of the atmospheric initial state elevates model skill. Skill is generally found to be lowest during the winter season for the dynamical seasonal forecasts, equal to that of the long...

Autores: Igbinosun, J.E.; Roberts, O.O.; Amako, D.
The possibility of wholly or partially replaced wheat offals with dried water hyacinth meal in the diets of Tilapia zillii fingerlings was investigated.  Four diets, A, B., C and D were formulated.  Diet A contain 45% wheat offal in addition to fishmeal and soyabean meal as sources of protein.  B and C were diets in which 100% and 50% of the wheat offals were replaced by dried water hyacinth meal respectively.  Diet D had 80% water hyacinth meal and an additional 18% Casein as the only other source protein. Results of four weeks feeding trial showed that Tilapia zillii fingerlings would not ingest diet D containing 80% water hyacinth meal without the addition of fishmeal.  Water hyacinth meal could not wholly replace wheat offals in Tilapia diets unless at...

Provedor de dados: 20
Autores: Bhagwant, S.; Elahee, K.B.
This paper reports on a preliminary study carried out on gill  tissues of two edible lagoon fish species, the yellowstripe goatfish (Mulloidichthys flavolineatus) and the flat head mullet (Mugil cephalus) from the Bay of Poudre d'Or, Mauritius, which is known to be contaminated with toxicants and sediments. Both light and scanning electron microscopic studies of the processed gills of these two fish species showed marked histological alterations. The pathologic lesions of the gills included ballooning dilatations or lamellar hyperemia; hypertrophy of the filament and lamellar cells; yperplasia of the filament and lamellar cells, and deformities of gill arches, filaments and lamellae.

Social Literature Review for the Knowledge in Fisheries Management Project
Provedor de dados: 20
Autores: Wilson, D.C.
Fisheries co-management has two agendas associated with it that sometimes work together and sometimes contend. The first agenda is to make fisheries management more rational, meaning making it better able to achieve its objectives. The second agenda is to make fisheries management more equitable by giving those people who have the most at stake in management decisions a greater say in those decisions. The knowledge on which co-management is based plays a critical role in both of these agendas. If the knowledge needed for management, for example about the condition of a fish stock, is more realistic and easier to get, this helps management to be more rational. If the knowledge needed for management is contributed to, shared and controlled by more...

Comparison of spectral partitioning techniques for wind wave and swell.
Provedor de dados: 20
Autores: Li, Shuiqing; Zhao, Dongliang.
The ocean waves are generally mixed with wind wave and swell. In order to separate these two kinds of ocean waves, many wave spectral partitioning techniques have been proposed. In this study, a two-dimensional(2D) and three one-dimensional (1D) wave spectral partitioning techniques (denoted as PM, WH, and JP) are examined based on the model simulations and in-situ observations. It is shown that the 2D technique could provide the most reliable results as a whole. Compared with 2D technique, PM and JP techniques obviously overestimate the wind-wave components, and the same situation happens for WH technique at low wind speed. With the adjustment of the partitioning frequency ratio, the 1D PM technique is modified, in which the result agree well with that of...

This work, it is applied a unidirectional and stationary model for estimating the dissolved oxygen distribution in the area of the Gulf of Batabanó, starting from the influence of physical-biological parameters (marine currents, temperature, salinity, photosynthesis and respiration). In this first approach, estimates of the dissolved oxygen concentration are obtained for Ensenada de la Broa, with an error of 0.2693 mg/L, while for the rest of the Gulf the estimate error oscillated between -4.13 y -4.69 mg/L. Consequently, it is concluded that the pattern is efficient for the estimate of dissolved oxygen concentration in Ensenada de La Broa, while for the rest of the Gulf it is not enough the consideration of primary production in the water column as only...

The effect of the Mbita Causeway on water currents in the region of Rusinga Channel, Winam Gulf, Lake Victoria: a 3D modelling study with ELCOM
Provedor de dados: 20
Autores: Romero, J.R.; Khisa, P.
The Mbita Causeway in Kenya was constructed in the early 1980’s to link Rusinga Island to the mainland to facilitate the transport of people, goods, and services to the island. One of the effects of the Causeway was to permanently block a secondary connection between Rusinga Channel and the offshore waters of Lake Victoria. This secondary channel may have served as a substantial pathway of exchange between Winam Gulf and Lake Victoria prior to the Causeway. There has been considerable scientific and political debate as to whether decreased flushing within the two bays on either side of the Causeway has occurred and led to poorer lake water quality since the construction of the barrier. In Apr.-May 2005 an intensive field investigation was undertaken to...

Autores: Li, Jialin; Wang, Yanhong; Zhang, Renshun.
Most of the flood from the wide inner lowland plain discharges through tide locks on coast, and the influence of tidal flat inning projects on the tide lock drainage must be solved by seawall line choice. Taking the Cangdongpian inning area on the west side of Tiaozini Sand as a case study, the paper analyzed the compages and validity of ebb tide water to maintain the flood discharge creek below the tide lock for different projects of seawall line. Result indicates that a rational seawall line program has little influence on the flood discharge of lock during the mean tide or general spring tides, but has certain influences during a storm surge or an extreme spring tide in autumn. However it could be resolved by several times of artificial scour on the...

One hundred oceanographic stations were occupied in front of Ecuador during september 1995. All the information were treated statically using the method of ”Kriging” to interpolate from this; surface distributions of sea temperature, sea temperature anomalies, air temperature, and atmospheric presion were obtained. These distribution with temperature and salinity profiles showed between normal and cold climatical conditions. Comparing the sea density horizontal distribution and the water mass, with the capture areas distributions of Sardinops sagax, resulted that areas with hight capture had AESS in low quantity and hand too a surface thermocline.

Co-managing the commons within the new governance structures of South Africa has the potential to promote participatory democracy and improve natural resource management. Inequitable access to and use of natural resources characterised apartheid-era policies and practices. In line with post-1990 democratisation processes, public involvement, participation, community-based initiatives and co-management have been promoted as key aspects of natural resource management policies. Power sharing, empowerment, organisational capacity building and improved natural resource management are some of the key principles of co-management within the South African context. This paper will explore the applicability of the co-management concept to the enhancement of rural...

A new contribution on the chemical aspects of the San Jorge Gulf benthic system in the distribution area of shrimp Pleoticus muelleri (Spence Bate, 1888) during 2005-2010 is presented. Concentration of dissolved oxygen in bottom water and mix layer and of total organic matter (TOM), total organic carbon (TOC), total nitrogen (TN), chlorophyll a (Chl a) and phaeopigments (Phaeo) in surficial sediments were analyzed. The origin and nutritional value of TOM deposited were also assessed through the C:N ratio. Water samples were collected during the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) seasonal research cruises in the period 2005-2010. Sediment samples...

The ecuadorian trawl fishery. 1974-1985
Provedor de dados: 20
Autores: McPadden, Ch.
Interview data, length frequency data and species composition for the Gulf of Guayaquil between 1974 and 1985 were examined. The data indicates a long term decline in landings of some 1,000 mt. The species most affected is Penaeus occidentalis which has shown an overall decline in landings. Landing Penaeus vannamei have increased in over the same period. It is not clear wether the decline in catches during 1984 and 1985 was due adverse enviromental conditions or overfishing by the fleet and postlarval.

A Coast in Common: An Introduction to the Eastern African Action Plan
Provedor de dados: 20
The coastline of Eastern Africa is an area of great physical beauty, rich in living resources. Palm fringed beaches of white coral sand lead down to tranquil lagoons enclosed by spectacular coral reefs with their wealth of colourful fish, shells and corals. The area has vast mangrove forests, high coral cliffs, wide stretches of sand dunes, and numerous offshore and oceanic islands. Yet there are problems in paradise-pollution, habitat destruction, and the pressures of growing populations and tourism. To face these common threats to their marine environment, the nine nations of the region are now working together to manage their shared resources and to find regional solutions to their problems. They are doing this under the auspices of the Eastern African...

Epibionts on Flexopecten felipponei (Dall, 1922), an uncommon scallop from Argentina
Provedor de dados: 20
Autores: Schejter, L.; Bremec, C.
Flexopecten felipponei (Dall, 1922) is a non-commercial, seldom reported pectinid from the SW Atlantic Ocean. In this contribution we review its taxonomy, describe epifaunal species and their levels of encrustation, and discuss the composition of the macrobenthic assemblage where this scallop Iives. Eighteen epibiont taxa were observed to Iive on the valves of these scallops. The most frequent and abundant epibionts on F. felipponei were serpulids, barnacles, and oysters. Although both valves were encrusted, the left valves had higher percentages of coverage. The benthic community contained 69 invertebrate taxa that generally charaeterize other mid-shelf bottorns between 37°S and 39°S. Eight pea crabs of the species Tumidotheres maculatus (Say, 1818)were...

Consideraciones sobre la alimentación de la caballa con especial enfasis en la depredación de huevos y larvas de peces
Provedor de dados: 20
Autores: Pájaro, M.
Adult and juvenile fish inter and intraspecific predation may be an important source on these first development stages. In this work, adult and juvenile mackerel samples from two areas of Buenos Aires province, one south of Cape San Antonio and the other near Mar del Plata city were analyzed. An important anchovy postlarvae ingestion in both regions considered was observed. A high number of mackerel eggs in the stomach contents from adults was identified. This evidence of cannibalistic behaviour in the argentine mackerel is the first of its kind made in this species and allows to suggest that embryo mortality due to cannibalism might constitute and important percentage of the total embryonic mortality.

Provedor de dados: 20
In view of the ongoing review of IODE, the planned development of an IOC data management strategy and the preparations of the JCOMM strategy it is important that the IODE data and information management community thinks about the prioritization of IODE activities and projects. There are currently a significant number of global and regional projects. Some of these are funded through donors but many require IOC funding. As the funding for IODE for the UNESCO regular programme is not likely to increase it is necessary to reflect on which projects IODE can afford to continue and which ones may need to end. Through the survey all IODE data managers and information managers were given an opportunity to express their opinion.

Age estimation of commercially exploited fish species in the Benguella region. Stocks of the two species of horse mackerel that occur in the Benguela region, namely Cape (Trachurus trachurus capensis) and Cunene horse mackerel (Trachurus trecae) are being exposed to increasing levels of commercial exploitation, highlighting the requirement for effective management measures to ensure their sustainable utilization. Such measures can only be implemented with confidence if they are based on reliable stock assessment procedures. Sizestructured stock assessment models have been found to be unsuitable for Southern African horse mackerel stocks, and the decision has recently been made to move to an age-structured VPA approach. A fundamental requirement for this...

Depth-related diversity patterns of free-living nematode assemblages on two tropical rocky shores
Provedor de dados: 20
Autores: Armenteros, Maickel; del Pino-Machado, Arturo; González-González, Susett; Ruiz-Abierno, Alexei; Pérez-García, José Andrés.
Depth-related spatial patterns of diversity have been described for free-living nematode assemblages at four depth horizons (intertidal, 1 m, 5 m and 10 m) at two subtidal rocky shores on the NW coast of Cuba: Bacunayagua and Miramar. The patterns were described based on species identity and biological traits. Species richness was similar across depth horizons ranging from 12 to 18 species; it was also similar between sites with 30 and 33 species for Bacunayagua and Miramar respectively. Diversity variation was higher between the intertidal and the subtidal horizons suggesting that microhabitat plays a key role. Depth was not an important driver of the diversity of nematodes on the studied rocky shores both in terms of species richness and diversity...

Predictability and Information Part I: Measures of Predictability
Provedor de dados: 20
Autores: DelSole, T.
The connection between predictability and information theory is discussed with the aim of clarifying the various metrics which have been proposed in the literature. This discussion begins with the following definition of predictability: an event is predictable if the posterior distribution, after a set of observations becomes available, differs in any way from the prior distribution which is known before observations become available.

Autores: Cuadra, T. de la.
In front of the ecuadorian coast, the subsuperficial thermic structure at the sea, was detected being warm during december 1994, as a result of the advection of high temperature water from the West Pacific to the East Pacific Ocean. This oceanographical condition appared different from those of december 1992, even when meteorological conditions seemed to be quite similar to those in 1992, even when meteorological conditions seemed to be quite similar to those in 1992. The appearance of certain ridgings that apparently are related to the botton shape would provoke an enrichment of disolved inorganical nutrients and therefore hight primary productivity. This in turn would imply that, in the sites redarded as ”bajos”, the potential fishery resources are...

Reef-associated fishes of Mozambique: What is known about them
Provedor de dados: 20
Autores: Pereira, M.A.M.
The first studies undertaken in Mozambique regarding reef fishes were carried out at Inhaca Island in the final 30’s (Lopes 1937; 1938). In the 50’s and 60’s, mainly taxonomic studies were conducted and reef fish species lists were made available especially for Inhaca Island (e.g. Smith 1958; Sanches 1963; Smith 1968). Only recently, investigations of other aspects of the reef fish fauna has begun. Kalk (1995) elaborated on the trophic composition of the reef fish fauna at Inhaca Island and Loureiro (1998) studied the artisanal reef fisheries in Mécufi District, north of Mozambique. Under the Darwin/Frontier Mozambique project (Whittington et al. 1998) the diversity, species composition, abundance and fisheries of the coral reef fish fauna of the Quirimbas...

Territorios del pez Stegastes planifrons en formaciones coralinas del Parque Nacional Natural Tayrona, Caribe colombiano: un panorama general
Provedor de dados: 20
Autores: Santodomingo, N.; Rodríguez-Ramírez, A.; Garzón-Ferreira, J.
The pomacentrid Stegastes planifrons is one of the most conspicuous inhabitants of the coral reefs and constitutes an important agent of natural coral mortality. These fishes kill coral directly by removing coral polyps for opening up a space for its algal turfs, which are their main food. The population density, territory and algal turfs areas of Stegastes planifrons were assessed at Chengue and Gayraca bays in Tayrona Natural Park, as a contribution to understand natural processes involved in the coral reef deterioration. During August to November 1999, belt transects (20 x 2 m) were evaluated at four reef habitat types: multispecific coral assemblages dominated by (1) Colpophyllia natans (COLP) or (2) Montastraea spp. (MONT); and monospecific coral...

Understanding Ocean Surges and Possible Signals over the Nigerian Coast: A Case Study of the Victoria Island Bar – Beach Lagos
Provedor de dados: 20
Autores: Afiesimama, E.A.; Olaniyan, E.
Eighteen different occurrence of ocean surge events over the beach of the Victoria Island in Nigeria were recorded between 1990 to 2002 and each with its devastating consequences resulting from the massive flooding and erosion. Statistical analysis and parametric wind-wave model were used to investigate the ocean atmospheric interactions in terms of their characteristics, especially before during and after every surge event from 1990 to 2002. It revealed that all ocean surges apart from the surge of March 2002 were experienced in summer months of April to October, but more frequent in August. Coastal atmospheric pressure was generally transiently low and observed to coincide with high tides. However, pressure varies from one event to another, between 1008...

Coelacanth has, for the first time, been found to occur off the Tanzanian coast. On the 9 September 2003, Coelacanth was caught by a fisher off Songo Mnara Island in Kilwa. The fish was caught in a net at a depth of 100m, which is only a few hundred meters from shore. The coelacanth, 132cm long and weighing 40 kilogrammes, was first kept at the Marine Parks and Reserves Unit in Dar es Salaam for processing before it is preserved and put on display at the National Museum in Dar es Salaam for public viewing. No coelacanth had ever before been recorded in Tanzanian African waters, so this was a very good find. And it came only few weeks after the Tanzanian Government through its National Coelacanth Committee hosted a research and training ship MV FRS ALGOA at...

Status of Coral Reefs in the Red Sea-Gulf of Aden
Provedor de dados: 20
Autores: Hassan, M.; Kotb, M.M.A.; Al-Sofyani, A.A.
The status of coral reefs bordering the Red Sea and Gulf of Aden is generally good, with live hard coral cover averaging 20-50%. There are predominantly fringing reefs bordering the coasts of Djibouti, Egypt, Saudi Arabia, Sudan, and Yemen. Atolls and pinnacle reefs occur mainly in the Central and Southern Red Sea. However, technical reports, personal observations and comparative data show recent decreases in live coral cover. Fish populations are also declining and there have been several small outbreaks of the crownof- thorns starfish (COTS), some local bleaching events and an increase in bioeroding organisms such as the urchin Diadema setosum and the coral eating gastropods Drupella and Coralliophila. Threats to coral reefs differ within the region, and...

Remote Sensing Needs and Capabilities In West Africa
Provedor de dados: 20
Autores: Koranteng, K.A.; Opoku-Duah, S.
The greatest advantage of remote sensing over conventional measurements lies in the opportunity to carry out detailed spatio-temporal analysis of land and ocean features on a very frequent basis. This paper analyses the contribution of satellite imagery to atmospheric, geophysical and ocean studies and management in West Africa since the early 1980s. The detailed application of data from optical sensors (e.g. Meteosat, NOAA/AVHRR, SPOT, Landsat TM, etc.) for weather prediction, hydrogeological, landuse/cover and cartographic studies has been acknowledged. However, the use of microwave (e.g. SAR) and optical data for ocean monitoring and studies in the sub-region is still very limited. Even though sufficient remote sensing expertise and infrastructure is...

El hallazgo no pudo satisfacer más las expectativas: decenas de esqueletos articulados, varios de ellos completos, pertenecientes al grupo de ictiosaurios platipterigios, es decir, el último grupo en desaparecer de la faz de la Tierra, hace unos 90 millones de años, a comienzos del Cretácico Superior.

Résumé : En Mauritanie, un constat clair met en évidence une tendance de sur-exploitation « en série» des stocks à haute valeur, des Mugilidés; le mulet jaune premièrement, puis ensuite le mulet noir et le mulet doré (espèces pouvant être considérées de substitution). L’exploitation intensive du mulet jaune à partir de 1996 a conduit au ciblage du mulet noir à partir de 1998 et puis, plus récemment encore, celui du mulet doré en 2001. L’absence d’une gestion rationnelle risque de conduire, dans moins de sept ans à la quasi-disparition de ces ressources (logiquement renouvelables).  C’est dans ce contexte de baisses des rendements, auquel s’ajoute la dégradation des zones littorales par l’action anthropique sans cesse croissante, que ce travail a permis...

Estimación preliminar de la mortalidad natural de la merluza de cola (Macruronus magellanicus) en la plataforma sur-patagónica (Argentina)
Provedor de dados: 20
Autores: Ehrhardt, N.M.; Prenski, L.B.
Long-tail hake, Macruronus magellanicus, is an important species in the Argentinean southern demersal species complex. Significant development of these fisheries since 1987 is indicative of the need to assess the hoki resource and for this purpose knowledge about some of the fundamental population parameters, such as natural mortality rate, is required. Knowledge on the natural mortality rate is an important element for the quantification of the resilience of the stock to fishery exploitatuib. In this study an algorithm for estimating natural mortality of hoki is developed which is based on information on abundance at age obtained from area swept methods and from age composition in the landings. As a result, natural mortality rates for ages 5 to 9 ranged...

Observations on the biology of the redlip Blenny, Ophioblennius atlanticus (Pisces: Blenniidae) on the Colombian Coast of the Caribbean
Provedor de dados: 20
Autores: Rylander, M.K.; Köster, F.
During a 3 week study, a total of 55 individuals of the redlip blenny (Ophioblennius atlanticus) were observed for at least two 15-minute periods, and several for ten of such periods. The sizes of their territories were estimated, the color pattern of each specimen an intra and interspecific interactions were recorded. The mean territory size of the redlip blenny in the study area appeared to be greater than that of these blennies studied in Curacao and Barbados by NURSALL (1977), the difference reflecting perhaps different methods of identifying the territories or a lower density of O. atlanticus in the Santa Marta área. Territories did not appear to be as consistently defended at the study area as at Barbados/Curacao and our impression ¡s that...

Autores: Galvis-Cortés, O.D.
A partir de septiembre de 1981 y durante 14 meses consecutivos de muestreo en la Ciénaga Grande de Santa Marta, se capturaron 3477 ejemplares de chivo cabezón Ariopsis bonillai (Miles, 1945). Con base en estas capturas, se estimó la relación tallapeso para hembras y machos en forma separada y en conjunto. Se obtuvieron las curvas de crecimiento según von Bertalanffy en talla y peso para ambos sexos y también los valores preliminares de las tasas de mortalidad natural (M), total (Z) y por pesca (F) Se analiza la variación de estos resultados entre sexos como una función causaefecto, originada por el fenómeno de la incubación oral característico en la especie.

Land use and Coastal Management in the third Countries; Egypt as a case
Provedor de dados: 20
Autores: Hamza, W.
Although the aspects of both land use and coastal management represent part of the larger concept of sustainable development, the strength and interest with which these aspects are received varies considerably among countries. It is well known that land use planning can facilitate the allocation of land to those use(s) that provide the greatest sustainable benefits. However, in order to achieve a sustainable land use planning, an in-depth analysis of the existing resources is required (e.g. localization, features, sensitivity to development). Furthermore, the understanding of development characteristics (resource needs and collateral efforts), would make it possible to identify the use of natural resources. In that regard Sense and Toccolini (1998)...

A preliminary assessment of coral bleaching in Mozambique
Provedor de dados: 20
Autores: Schleyer, M.; Obura, D.; Motta, H.; Rodrigues, M.J.
The 1997-1998 El Niño southern oscillation caused elevated sea temperatures that resulted in global coral bleaching. Coral reefs constitute an important biological resource in terms of their complex biodiversity and are the basis for tropical fisheries and marine ecotourism. They represent one of Mozambique’s main coastal assets, and coastal communities and the growing tourism industry rely mainly on reef-based resources. Today, about 6.6 million people live within Mozambique’s 48 coastal administrative districts. This represents 42% of the current population (15.7 million), which is expected to grow at 3% p.a. (INE, 1998). In 1994, the population density in coastal districts was 28 persons/km2. In 1996, much higher densities were recorded in the coastal...

Autores: Gichuki, J.; Maithya, J.; Masai, D. M.
Studies on the ecology of Lake Sare (Kenya) were carried out to provide baseline information on the ecological conditions before a major wetland reclamation project was started upstream of the lake. Results indicated that maximum depth had decreased by 0.9 m while Secchi depth readings had decreased by 0.1 m compared to historical values. This implies that the lake was undergoing siltation. pH values had increased from 6.80 to 7.58 reflecting increased primary production. Conductivity had increased from 106 – 137 2 ~kS/cm. NO3- N and PO4-P had significantly increased from 0.8~kg N l-1 and 0.14 ~kg P l-1 to 23.90.8~kg N l-1 and 34.80.8~kg P l-1 respectively while chlorophyll a values reached 34.8 ~kgl-1.

Autores: Wang, Guiling; Jiang, Weimei; Wei, Ming.
Characteristics of urban heat island (UHI) effect and its cause are investigated by using MODIS data in April 2004. Surface parameters from the MODIS data have surface temperature (ts), albedo(a), and normalized difference vegetation index (NDVI). Their heterogeneities over urban and rural area are analyzed based on land cover classification, and their relations are also presented in order to explain the UHI effect. The results show that there exists obvious the UHI effect. Ts over urban areas are by 10.83 % higher than those over rural area，and NDVI and a over urban area are by 62 % and 18.75 % less than those over rural area, respectively. Surface temperature has significantly negative correlation with NDVI and their correlation coefficient is -0.73....

Biophysical isopycnic-coordinate modelling of plankton dynamics in the Arabian Sea
Provedor de dados: 20
Autores: Idrisi, N.; Romanou, A.; Olascoaga, M.J.
A Nutrients-Phytoplankton-Zooplankton-Detritus (NPZD) ecosystem model is coupled to the Miami Isopycnic-Coordinate Ocean Model (MICOM) to study planktondynamics in the Arabian Sea. Experiments oriented to testing the NPZD-MICOM coupled model sensitivity to variations in several parameters are performed. Particular attention is paid to the rates of detritus sinking and maximum phytoplankton growth rate. The coarse features of the blooms are captured by all the experiments considered, and agree with earlier models for the biological activity of the region. Intensity, duration, and peaks of the blooms are found to be quite sensitive to the parameter choices. The existence of an offshore deep chlorophyll maximum in the model is found to be closely related to...

Apatite Fission Track Analysis of Sites 959 and 960 on the Transform Continental Margin of Ghana, West Africa
Provedor de dados: 20
Autores: Carter, A.; Clift, P.D.; Hurford, A.J.
Four samples of sandstone from deformed Aptian–Albian sediments and their less deformed Turonian cover at Sites 959 and 960 on the Côte d’Ivoire-Ghana Marginal Ridge yielded sufficient apatite for fission track analysis. Reduced mean track length values of 12.42 ± 0.16 μm to 13.67 ± 0.11 μm indicate that measured central ages, which range from 88 ± 4 Ma to 113 ± 4 Ma, have undergone partial resetting and are therefore apparent ages. Stochastic modeling of the fission track age and length parameters indicate that the samples have a strong predepositional signal, slightly modified by minor levels of prolonged postdepositional annealing (maximum temperatures &lt;80°C). The preserved provenance-related signal records cooling through the apatite partial...

A Preliminary Investigation of the Effects of Human Physical Disturbance on the Ecology of the Soldier Crab Dotilla fenestrata (Crustacea, Ocypodidae) at Praia da Costa do Sol, Maputo
Provedor de dados: 20
Autores: Gonçalves, P.M.B.; Pereira, M.A.M.
The effects of human trampling on the population parameters of the soldier crab Dotilla fenestrata at Praia da Costa do Sol, Maputo were studied in two areas subjected to two different levels of human disturbance: (1) a low disturbance area; and (2) a high disturbance area. Sampling was carried out 1 day before and 1 day after disturbance took place and crab abundance and biomass data were compared between the two periods at each area. No significant differences (P &gt; 0.05) were found between abundance and biomass values before and after the disturbance. These results suggest that human trampling has an insignificant effect on D. fenestrata and that behavioral and habitat structure aspects might play more important roles on the population ecology of the...

Autores: Liu, Jianhua; Gao, Jinyao; Fang, Yinxia; Wu, Shuigen.
Based on the data of seismic reflection, seismic refraction and magnetism collected in the research area and geology obtained from adjacent areas, this paper deals with the issue of basement constitution of the southern part of the Okinawa Trough. In the shelf basin of the East China Sea, Taiwan folded belt and Ryukyu Islands folded belt which surround the trough, outcrop Later Paleozoic, Mesozoic and Eogene strata. In the southern trough, multichannel seismic reflection data indicate that the overlying strata are composed of Neogene and Quaternary deposits, and the acoustic basement consists of Eogent and even older strata. Seismic refraction profiles show that there are Eogene and Mesozoic velocity layers with longitudinal velocities of 4.7 - 5.3 km/s...

Estructura de la comunidad epifaunal asociada a colonias de vida libre del Hidrocoral Millepora alcicornis Linnaeus 1758 en Bahía Portete, Caribe colombiano
Provedor de dados: 20
Autores: Castro S., C.; Monroy L., M.; Solano, O.D.
The epifaunal community associated with free-living colonies of Millepora alcicornis, the dominant coral species in Portete Bay, was characterized from twenty living colonies randomly collected within a shallow Thalassia testudinum seabed. The three-dimensional growth colonies sheltered 15 families, 15 genera and 18 mobile invertebrate species. The 97% of individuals was represented by decapods crustaceans specially adapted as to live in association with the host. Within them, the porcelanid Petrolisthes armatus, representing 79% of the epifauna (961 individuals), was exclusively found in a juvenile stage suggesting that M. alcicornis is mainly used by this species as a nursery zone. The epifaunal composition is partially related to coral living tissue...

Autores: Ibe, A.C.
Previously published data and preliminary indications from research now in progress suggest the possible occurrence in offshore Nigeria of economically viable deposits of placer minerals (including heavy minerals), sand and gravel, phosphorite, glauconite, polymetalic manganese nodules etc.  In addition, new stratigraphic evidence indicates the existence of potentially rich petroleum plays associated with a Tertiary canyon system in water depths beyond the limits of present exploitation.  Based on the comparative geology of similar occurrences in better explored continental margins and ocean basins elsewhere, the possible origin, abundance and distribution of these resources are adduced.  A brief assessment of the technology relevant to their discovery and...

Autores: El-Haweet, A.; Hegazy, M.; Abu-Hatab, H.; Sabry, E.
Scales reading and length frequency distribution were used for age determination and growth estimation of Boops boops (Bogue) stock of Western Mediterranean Coast of Egypt. Age determination using scale was done and the time of annulus formation was detected by the marginal increment index. Bhattacharya’s method was used for length frequency analysis. Both methods showed 6 age groups. ANOVA test revealed insignificant differences between both estimates of length at age results. Growth parameters estimated using length-at-age data from both methods confirming the age determination results. Growth performance index indicated high similarity between the two estimates. The results revealed the compatibility of length frequency distribution to scale reading for...

Áreas potenciales de descarte de merluza para la actividad de la flota comercial argentina
Provedor de dados: 20
Autores: Dato, C.V.; Villarino, M.F.; Cañete, G.R.
To improve the quality of the resource assessment it is necessary to estimate discards and quantify them applying an adequate methodology. The purpose of this work is to detect areas where the activity of the commercial fleet coincides with zones of high concentration of juveniles because they are potential discard areas. To establish possible seasonal and/or interannual variations, length distribution data derived from hake research surveys carried out on board of INIDEP vessels during the 1986-1993 period were analyzed. Samples were grouped per statistical rectangle on the basis of catch weighted average and mean, variance, skewness and kurtosis were calculated. The resulting parameters were subjected to a cluster analysis using the Euclidean distance...

The Patagonian grenadier Macruronus magellanicus fishery reached the maximum exploitation in the argentine fishery in 1988 with a catch of 154,960 t, decreasing gradually in the current decade. Statistical data confirm this trend and consider a total catch of22,796,3 t for 1995. The regulations establish a minimum of 120 mm inside codend mesh size for demersal species in Argentine sea. Hoki,in relation to the fishing gear, shows a semipelagic behaviour, but no selectivity trials were made at the moment. The present report presents the selectivity results obtained with rough bottom trawl Engel net with a double braided PE twine codend and 120 mm mesh size.Except the codend, it is the gear normally used by INIDEP to evaluate demersal resources.

Evidencia de ondas ecuatoriales en Salinas y Galápagos
Provedor de dados: 20
Autores: Bayot, B.; Cornejo Rodríguez, M.P.
La importancia fundamental de estas ondas en las regiones tropicales (30°S-30°N) y especialmente en el sector ecuatorial (5°S-5°N), radica en que al propagarse más rápidamente que en regiones subtropicales, permiten un ajuste oceánico más rápido y eficaz ante cualquier alteración oceano-atmosférica. Sin embargo las ondas "interesantes" son las que transmiten cambios anormales, ya que en algunos casos lo hacen sin dispersión. Por ejemplo, las ondas Kelvin que son originadas en el Pacífico Ecuatorial Occidental, por la supresión o cambios de dirección de los vientos del este y coherentes con eventos ENOS, viajan a lo largo del Pacífico Ecuatorial hasta chocar con el continente sudamericano.

La boutargue est constituée par les ovaires salés et séchés des mulets à grosse tête (Mugil cephalus) et de la courbine (Argyrosomus regius) représente une ressource importante pour la région de Nouakchott  et pour la Mauritanie. Pour déterminer la valeur énergétique dans les boutargues, nous avons effectué des dosages des protéines, des glucides, des lipides et des études analytiques des acides gras et des lipides. Les analyses ont révélé que la boutargue contient, par rapport aux autres éléments d’énergie, très peu de glucide : 3,29% dans la boutargue du mulet et 1,95% dans celle de la courbine.

GIS-based integration of interdisciplinary ecological data to detect land-cover changes in creek Mangroves at Gazi Bay, Kenya
Provedor de dados: 20
Autores: Koedam, N.; Dahdouh-Guebas, F.; De Wulf, R.; Tack, J.; Obade, P.T.
Historic environmental, faunal, floral and socioeconomic data of Gazi Bay in coastal Kenya were collated and integrated into a GIS environment and data of impacts due to various factors were then related to remotely sensed data. Rhizophora mucronata, a valuable mangrove species, was investigated. Very low values of basal area (7.7 m2/ha and 4.9 m2/ha) and complexity indices (1.86 and 1.12) at Makongeni and Kinondo 1, respectively, reflected intense human pressure in these areas. Areas that were easily accessible or close to human settlements appeared more vulnerable. Accrued information from a socioeconomic survey carried out over the same period corroborates the hypothesis that human influence was a major contributor to these changes. Historic aerial...

Autores: Amadi, I.F.
The desire of the nation has been to attain self–sufficiency in food production by the year 2000.  More importantly, the need is to increase the animal protein intake of the average Nigeria, which has been low, at about 19.38g/Capita/day, far below the 65 g/Capita/day recommended by FAO in the light of its identification as the indicator and determinant of dietary quality.  In the agricultural sector, all fisheries products have great contributions towards the provision of animal protein thus the concern for constant improvement of the fisheries sub-sector of agriculture.  Successive governments in Nigeria have introduced several measures to achieve increase in food production.  As it affects the fisheries sub-sector, one of the identified constraints to...

Autores: Daniels, C.; Fanning, E.; Redding, D.
Abstract—In collaboration with local stakeholders, Frontier-Tanzania is collecting biophysical information to facilitate effective management initiatives for Misali Island, where marine resource management is currently limited to a 1.4-km2 non-extraction zone within a 21.6-km2 conservation area. In the study reported here, the extraction and non-extraction zones at Misali Island with similar substrata were compared. Data analysis showed a significant disassociation in both abundance and mean length patterns of fish families found in each zone. Further analysis using t-tests on individual families showed that some groups were significantly more abundant in either zone, but without significant differences of mean lengths. Fish family abundance and length...

Recent developments, involving an informal community of software developers, data  archivists and the IODE SG/OT, have led to a significant breakthrough in access to operational  oceanographic data for training, national data collecting, and analytical synthesis work. However,  due to their very “operationality” the data have received only basic quality-control, and new  operational data cannot be simply added to existing collections without ensuring they meet the  specified QC criteria.  Instruction on data quality control concepts and procedures is already  covered during training workshops and the tools are available to visually inspect new data.

La acuicultura continúa siendo el sector de más rápido crecimiento en la  producción de alimento de origen animal. Esta actividad se practica e  intensifica en casi todas las regiones del mundo, debido a la elevada demanda  de alimento de origen acuático por la población mundial y al hecho de que  muchos recursos pesqueros han llegado  a su máximo nivel de explotación en  ambientes naturales.   Entre los cultivos con mayor interés se encuentran los crustáceos, que  aunque solo representan por el peso el 9,5 % de la producción acuícola mundial,  contribuyen en más de un 23 % al valor total de esta actividad de forma global,  solamente superados por los peces de agua dulce (FAO, 2010).

The recent descriptions of Potamonautes dentatus, P. clarus and P. lividus have brought the number of species recorded from KwaZulu-Natal (South Africa) to five, with P. depressus depressus and P. sidneyi having long been known from the province. To determine and quantify levels of genetic differentiation between these species, 14 populations were analysed using allozyme electrophoresis of 14 presumptive loci. Interspecific genetic identity-values ranged between 0.224 and 0.793 (D = 0.233 to 1.495), with between one and ten fixed allele differences present among species. Morphometric differentiation between species was examined using discriminant function analyses of seven carapace and eight pereiopod variables. Species were found to be well defined along...

Autores: Sánchez, R.P.
Through the analysis of the morphological changes ocurring in the process of growth, it was possible to identify three stages (primary juvenile: 25-75 mm; secondary juvenile: 76-160 mm; and juvenile preadult: 161-250 mm)during the first year of the species life. Regression equations for the different relations studied: body weight/body lenght, body surface/body lenght, body surface/body weight, and metabolic rate/body lenght, have been calculated for each stage. The variation of the number of gill rakers, mean distance between adjacent rakers and mean values of gill rakers lenght in reference to body growth was studied, and the relation between filtering area and body length was established.

Biodiversity is a holistic concept which encompasses what the scientific literature describes as inter-specific diversity (diversity between species), intra-specific diversity (genetic diversity) and diversity of ecosystems. As a support of life, the preservation of biodiversity in terrestrial and marine habitats is of primary importance for the ecological balance of the Earth. Moreover, it is essential for human beings whose lifestyle depends on nature. The value of biodiversity lies with the opportunities provided to mankind to adapt to a changing environment. Concerning specifically the seas and oceans that constitute ¾ of the planet and 90% of the biosphere, there is a renewed ‘ecological awareness’ at the global level on the need to preserve marine...

Autores: Busutil, L.; Hansel Caballero, H.; Hidalgo, G.; Alcolado-Prieto, P.; Alcolado, P. M.
Se determinó la condición del bentos de los arrecifes coralinos del polo turístico Santa Lucía (nordeste de Cuba) antes y después del paso del Huracán Ike, a partir de indicadores biológicos de la metodología AGRRA. Se evidenció un gran deterioro de la cresta arrecifal desde el primer muestreo. El arrecife frontal  presentó mejores condiciones que la cresta, fundamentalmente hacia el este y hacia las mayores  profundidades. Los valores bajos de la densidad de corales, la cobertura viva de coral y del reclutamiento  de corales, así como la gran cobertura de macroalgas fueron las variables más críticas. La incidencia de  enfermedades microbianas y de blanqueamiento de corales fue baja. Las causas más importantes de  afectación al arrecife coralino muestran...

Provedor de dados: 20
Autores: Knapp, L.W.; Imamura, H.
A new bembrid, Bembras adenensis, is described on the basis of specimens collected from the Gulf of Aden, western Indian Ocean. This species is easilydistinguished from B. japonica, the only known congener of the genus, by thefollowing combination of characters: larger orbital diameter, longer head length,pectoral-fin with a small black blotch near tip of upper rays, 3 gill rakers on upper gillarch, 19 pectoral-fin rays, and 15 anal-fin rays (vs. smaller orbital diameter, shorter head length, pectoral-fin with several small spots forming irregular bands, 2 gill rakerson upper gill arch, usually 17 pectoral-fin rays, and 14 anal-fin rays in B. japonica).

A total of 807 Dipturus chilensis specimens (448 males and 359 females) caught in research cruises performed by the National Institute for Fisheries Research and Development (INIDEP) during 2011 and 2012 were analyzed. The cruises were carried out between (34°S-48°S) and 50-313 m depth. Mean size at first maturity (TL50) was estimated at 780 mm and 908 mm TL for males and females, respectively, values that represented about 80% of the respective maximum total length observed. Besides, latitudinal differences in sexual maturity estimates were detected. The total number of 4-7 reproductive seasons and 42-52 follicles or individuals of maximum annual potential fecundity estimated in this paper allow to suggest that each female would produce less than 300 eggs...

Ecological studies on fish farms of el-fayoum depression (egypt)
Provedor de dados: 20
Autores: Konsowa, A.H.
This study was carried out at the fish farms of El-Fayioum province during 2003 farming season. They extend along the eastern bank of Lake Qarun. These farms derive its water and drainage wastes into Diar El-Berka Drain. pH values at the chosen farms ranged between 7.43 and 8.91 and its values are certainly optimum for fish culture. Salinity levels at fish farms adjacent to Lake Qarun (Goda 2, 9.5‰) are generally much higher than the other fishing ponds due to seepage from the lake water. The major nutrient concentrations (N &amp; P) at the main feeder were much higher than the corresponding values at fish farms. Nitrogen concentrations that represented by NO2-N, NO3-N and NH4-N indicated the dominance of NH4-N over NO2-N and NO3-N at the selected fish...

Provedor de dados: 20
Autores: Jaspars, M.; Dzeha, T.; Tabudravu, J.
The triterpenoid clionasterol (1), a 29 carbon structure compound was isolated from the less polar extract (20% EtOAc in hexanes) of the green alga Halimeda macroloba collected at Shimoni near Mombasa, Kenya. The structure and relative stereochemistry of this compound was elucidated by spectroscopic data, mainly NMR and mass spectrometry. This metabolite was inactive against DLD-1 cells on the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Further experiments on mosquito larvae and brine shrimp lethality confirmed this result.

Autores: Bowden-Kerby, A.
Of the planet’s 600,000 km2 of coral reefs (Jameson et al., 1995), roughly 70-80% are located in developing countries. Many of these reefs are owned or controlled by indigenous fishing communities rather than national or state governments. These rural fishing communities are a primary force of destruction to coral reefs on a global scale (Wilkinson, 1998), therefore their involvement in the management and conservation of coral reefs will be an essential part of reversing coral reef decline....

The contents of this document relate principally to a proposal for an autonomous Marine Resources Research Centre in Mauritius. The Consultant concluded that such a Centre lacked Justification at this time. The priority marine resources research was identified as being concerned with fisheries, mariculture and environmental studies (of the lagoon surrounding Mauritius). Most of these activities are already being undertaken within the Fisheries Research and Development Division (Ministry of Agriculture, Fisheries and Natural Resources). It Is proposed that this arrangement continue- but that the Division be re-organized to form part of a broader fisheries department type structure.

Autores: Liu, Guirong; Kang, Xianjiang; Guo, Mingshen; Sun, Wenjia; Wang, Qi.
Ultrastructural cytochemical techniques and electron microscopy were used for localization of acid phosphatase activity during spermiogenesis in Eriocheir sinernsis. The results showed that: Acid phosphatase was synthesized in the endoplasmic reticulum in the early spermatids. The acid phosphatase was found gradually in nucleus, the membrane of acrosomal vesicle, the cytoplasmic region and the acrosomal tubule. And then the reaction product particles became thicker during the spermiogenesis. In the mature sperm, acid phosphatase was localized in the percutor organ slightly, but it was massive and compact in the acrosomal tubule.

Autores: Grandcourt, E.M.
The mothership/dory fishing operation 'Pecheur Breton' spent 13 days fishing at the northwestern submarine promontory of Saya de Malha Bank between 24th February and 14th March 1993. The mothership fished using 12 dories which were equipped with echo-sounders and electric fishing reels. A total of 74.3 tonnes of fish was caught in the depth range of 55 to 130 m. of which the blue spotted jobfish (Pristipomoides filamentosus) represented 80%. The catch rates were observed to decreased with time and could not be attributed to changes in climatic conditions, fishing depth, fishing method or bait type.  The initial biomass of Pristipomoides filamentosus at the northwestern submarine promontory of Saya de Malha Bank was estimated at 76.1 tonnes through...

Geomorphology, ichthyofauna, water quality and aesthetics of south african estuaries
Provedor de dados: 20
Autores: Cooper, J.A.G.; Harrison, T.D.; Ramm, A.E.L.
The South African 3 000 km coastline has approximately 370 outlets to the sea ranging from small coastal streams to large permanently open tidal estuaries. The current state of scientific information on the vast majority of these systems, however, is virtually nil. As part of a national program to assess the state of South Africa’s estuarine environment, basic surveys were conducted on these systems during the period 1992 to 1999. This included ichthyofauna (fish), water quality, and geomorphological and aesthetic observations. Some 67% of South Africa’s ‘estuaries’ have been surveyed to date. This baseline data has been analysed and synthesised to render it understandable to the non-specialist but at a sufficiently high level to inform potential end users...

Autores: Sánchez, M.F.; Prenski, L.B.
This work is a first approach in the study of the trophic ecology from a multispecific fishery in San Jorge Gulf (45°-47°S), Argentina. Stomach contents from 28 demersal fish species were analyzed. Taxonomic and trophic spectrum were obtained. Using weight percentage of each prey, trophic spectrum variations for size classes were analized for each of the 12 considered "dominant" species. Overlaping in the diet among these predators was estimate using cluster analysis. There was an interespecific diet overlap between juveniles belonging to demersal-benthic fish species, because all of them prey upon Stomatopoda and Munida. Adults from those species and hake prefered young and adult hake as preys, while Macruronus magellanicus and juvelines Merluccius hubbsi...

This paper describes a simple method of producing a protein-enriched sweet biscuit, shown to be popular with young children, by adding cooked minced shark flesh and soya flour to a slightly modified biscuit formulation. The biscuit can be manufactured on standard production equipment at a cost which renders it ideal for use in institutional feeding programmes, the product´s extended shelf life being an additional advantage, especially in remote rural areas. Acceptability tests were carried out amongst 1,750 school children in poor communities both in the Andes and in Guayaquil. The children were fed biscuits (12,35 g) per day, of wich an average of 96,7% in Guayaquil and 99% in the Andean areas were consumed immediately. Acceptance was high and fishy...

El fitoplancton es uno de los componentes más abundantes de la biodiversidad de la Bahía de Cienfuegos. Se estudió el impacto de la temporada ciclónica 2005 sobre la composición y abundancia de estos organismos en el período de marzo-octubre. La composición específica de microalgas planctónicas de la bahía en marzo estuvo dominada por diatomeas y dinoflagelados marino-estuarinos como Nitzschia  longissima, Thalassionema nitzschioides y Prorocentrum micans. Al final de la temporada ciclónica, los cambios en la estructura de la comunidad fitoplanctónica fueron drásticos, prácticamente no se registró fitoplancton marino en la bahía. Las microalgas dulciacuícolas de los géneros Chlorella, Monoraphidium, Cyclotella, Aulacoseira, Pseudoanabaena, Planktothrix,...

During april 1995 hydrochemical research in a vertical column on the east side of the Galápagos Islands (Cruise T95/04/01) onboard of the INP R/V Tohallí indicated that concentrations of ammonium, nitrate, phosphate and chlorophyll-a were found stratified from the surface to deeper layers, on the other hand the maximum levels of nitrite and silicate were detected 70 m below the thermocline. The apparent oxygen use (AOU) varied from 1 to over 3 below the thermocline, this would indicate an oxidating environment due to the high levels of nitrate, phosphate, silicate and low concentrations of dissolved Oxygen (ca. 90-134[µM]) and ammonium (&lt;0,1[µM]). According to the high salinity average (35,0 ups), nutritive elements (nitrate 15,6 [µM], silicate 13,1...

Microzooplankton community composition in the north of South China Sea was investigated during autumn (between September and October), 2004. Dilution technique using chlorophyll a (Chl a) was employed to estimate grazing rates and grazing pressure. The results showed that Polymenophorea Oligotrichida was the dominant group with 16 species, and there were 4 species in Oligotrichina and 11 species in Tintinnina. The ciliates abundance ranged from 9 to 102 ind/m3. Instantaneous growth rates of phytoplankton (k) varied from 0.03 / d to 2.13 / d. Grazing rates of microzooplankton(g) ranged between 0.01 / d and 1.06 / d. The grazing pressure on initial phytoplankton stock (Pi) and primary production (Pp) was 0.089 % - 65.23 % and 33.63 % - 86.04 %, respectively....

We analyzed variation in the advertisement calls among three localities of Eleutherodactylus glamyrus, a frog endemic to the Sierra Maestra mountains in Eastern Cuba. We assessed the levels of withinmale variation of each call property and the influence of temperature and size of calling male on acoustical features. The typical single-note advertisement call of the species was described using temporal and spectral parameters. Rise time and frequency modulation were highly variable within individuals, whereas dominant frequency and call duration were the most stereotyped properties. Call rate showed an intermediate level of variation. Air temperature strongly influenced call rate and call group duration. Snout–vent length (SVL) strongly influenced dominant...

Prises accessoires des pêcherie crevettière et merluttières spécialisées dans les eaux mauritaniennes : Evaluation qualitative
Provedor de dados: 20
Autores: Diop, M.
Résumé L’analyse des échantillons prélevés sur les captures des crevettiers et merluttiers espagnols opérant dans les eaux mauritaniennes entre 1991 et 1994, a montré que ces pêcheries engendrent beaucoup de prises accessoires. Ces dernières varient entre 87% et 89% pour la pêcherie crevettière et dépassent 64% pour la pêcherie merluttière. Le rapport prises accessoires/capture espèce cible varie donc de 7 :1 à 8 :1 pour les crevettiers et se situerait à environ 2 :1 pour les merluttiers. Les prises accessoires sont constituées principalement de poissons démersaux (représentés essentiellement par les sparidés), de céphalopodes (poulpe, seiches et calmar) et de petits pélagiques. Les poissons démersaux sont largement dominants.

As a general rule, sharks and rays play an important role in the energy exchanges among higher trophic levels of the marine food chain and some of them, with an important impact as piscivorous predators.  Squalus acanthias (Squalidae) and  Raja flavirostris (=Dipturus chilensis )(Rajidae), are two elasmobranchs with high apparition frequencies in the SW Atlantic, in the coastal and demersal fishing trawls, co-existing and predating on the principal stocks of bony fish there located, especially the Argentine hake (Merluccius hubbsi). Both species could be transformed into alternative fishing resources, even though they are not currently commercially developed as such.

The main objective of the State of Environment in Africa report is to identify and highlight the major environmental issues of concern on the continent and to make recommendations for action. The information presented confirms that the state of the environment in Africa has been (and continues to be) influenced principally by rapid population growth, increasing and chronic poverty and inappropriate development practices, especially agriculture production methods. These factors have led to what has become popularly known as the population-agriculture-environment nexus. Other factors include unfavourable terms of international trade, the debt burden, the impact of drought and other natural disasters, and ineffective development policies. The cumulative...

The spatial and temporal distribution of the shrimp Artemesia longinaris in Fortaleza Bay, northern coast of Sao Paulo State, Brazil, in relation to abiotic factors, was studied. Shrimp samples were obtained on a monthly basis from November 1988 through October 1989 at seven pre-delimited transects on board of a fishing vessel supplied with double otter trawl nets. Depth was recorded at the midpoint of each transect; water and sediment samples were taken to measure salinity, temperature, texture and organic matter content of sediment. The shrimps obtained in the trawls were sorted, identified and 100 g subsample at each transect was separated for measurements (carapace length). A total of 3,083 individuals were obtained. Shrimps were more abundant from...

Autores: Keeley, R.
The Ocean Observations Panel for Climate and its predecessor examined the usefulness of surface salinity data in the context of climate change detection. They stated that "At high latitude, sea surface salinity is known to be critical for decadal and longer time scale variations associated with deep ocean over turning and the hydrological cycle. In the tropics, and in particular in the western Pacific, and Indonesian Seas, and in upwelling zones salinity is also believed to be important." They quote the benchmark sampling strategy to be one sample per 200 km square every 10 days and with an accuracy of 0.1 PSU. They also state that the tropical western Pacific and Indian Oceans and high latitudes should receive the highest priority.

The industrial tuna fishing activity in the western Indian Ocean, report for the year 1999 : Impact on the economy of Seychelles
Provedor de dados: 20
Autores: Commetant, B.
The fishing industry of the Seychelles economy has from its outset been one of the main traditional economic activities and stands to remain an important pillar of the country's economy. It is a valuable source of revenue in terms of earnings from licence fees issued, fishing vessels and companies' expenditures on local purchases of goods and services in addition to creating job opportunities notwithstanding the important amount of foreign currency that it earns the country. At the end of 1999 and throughout the last decade, Port Victoria maintained its position as the principle tuna port in the Indian Ocean. This was partly due to Seychelles central position in the Western Indian Ocean and its close proximity to the tuna fishing grounds. The port...

Development of a Marine XML
Provedor de dados: 20
Autores: Searle, Ben.
The necessity to access greater quantities of marine data to support a broad range of maritime activities has been increasing rapidly over the past few years. Larger quantities of data combined with a greater need to make existing data more accessible is making the task of the marine data manager increasingly more difficult. Today the information systems that are used to support marine data management are generally developed specifically for each individual agency.  The systems are developed to support an agencies specific need and more importantly their specific data formats.  This leads to inefficiencies in system development and promotes proprietary data structures further complicating data exchange and data fusion activities. The IODE community is only...

Autores: Fabré, N.N.
Los lenguados constituyen un importante recurso pesquero en el Mar Argentino. Más que en los volúmenes desembarcados (9 .731 t en 1991), esta importancia se centra en su elevado valor de comercialización debido a la alta calidad de su carne. Atendiendo a los desembarques totales realizados en el Mercado de Concentración Pesquera de Mar del Plata, los lenguados ocupan el octavo lugar. Estos desembarques están compuestos principalmente por especies de porte mediano a grande pertenecientes al género Paralichthys, y por ejemplares de tamaño mediano o pequeño de las especies Xystreuris rasile, y en menor proporción, Paralichthys isosceles. Este recurso es explotado, en el sector bonaerense, por las flotas de rada o ría y costera, mientras que la flota de altura...

Effets de la congélation sur le profil protéique des filets de la Dorade royale (Sparus aurata): comparaison entre le poisson sauvage et d’élevage
Provedor de dados: 20
Autores: Attouchi, M.; Sadok, S.
Les variations des profils éléctrophorétiques des protéines sarcoplasmiques (SPP) et myofibrillaires (MFP) chez les filets de la Dorade royale d’origine sauvage et d’élevage congelés à -18°C ont été suivies durant 4 mois de stockage. A l’état frais, la différence de l’origine de production de la Dorade (sauvage/aquaculture) n’a pas illustré de distinctions particulières dans les profils protéiques des filets. Durant le stockage congelé, l’analyse densitométrique des profils MFP et SPP chez les deux populations de Dorade a permis de discerner des modifications mineures liées à l’origine de production du poisson et à la progression du temps de stockage. Ces faibles changements, notamment dans la fraction MFP, ont été plus précoces chez la Dorade d’élevage....

Geochemical and sedimentology of core sediments and the influence of human activities: Qusier, Safaga and Hurghada Harbors, Red Sea Coast, Egypt
Provedor de dados: 20
Autores: Mohamed, A.W.
The grain size distribution and arameters, major and trace elements, carbonate, total phosphorus, organic carbon and total organic matter has been assessed for core sediments collected in the intertidal area of Qusier, Safaga and Hurghada harbors in July 2002. Mud is the dominant fraction in almost all samples of Qusier core and some samples of Safaga and Hurghada cores. The reason for the high mud content of all Qusier core samples and some samples of Safaga and Hurghada cores is due to the terrigenous flux of wadies, phosphate deposits, landfill and dredging in these areas. Metals concentrations in the core sediments vary between sites within a wide range for Cu, Zn, Pb, V, Ni and Cd. Concentration of metals in the sediments at the top of cores is the...

Seychelles tuna bulletin : fourth quarter 1990
Provedor de dados: 20
The number of purse seiners active in the western Indian Ocean average 41 during the fourth quarter compared to 49 vessels during the same period last year.  Fishing activity was high during the first half of the year with a record of 54 vessels present in February and March. The overall fishing results for the year were not as good as those previously recorded in the last three years.  Catch rates averaged 16MT/day compared to 18 MT/day in 1989 and 22 MT/day in 1988, attaining a similar level to results of 1986.  This was due to poor fishing conditions during January to May causing several vessels to leave the Indian Ocean in June.  However this situation changed as catch rates improved during the second half of the year, with exceptionally high yellow...

Fecundity of the pantropical fiddler crab Uca annulipes (H. Milne Edwards, 1837) (Brachyura: Ocypodidae) at Costa do Sol mangrove, Maputo bay, Southern Mozambique
Provedor de dados: 20
Autores: Litulo, C.
Uca annulipes (H. Milne Edwards, 1837) is probably the most abundant brachyuran crab inhabiting mangrove forests in East Africa. However, its fecundity is poorly understood. Crabs were randomly sampled during spring low tides from January to April 2002 at Costa do Sol mangrove, Maputo Bay, southern Mozambique. Carapace width (CW), abdomen width (AW), weight (W) and egg numbers (EN) were recorded. The average fecundity was 1599 ± 842 eggs, ranging from 529 (CW = 5.0 mm) to 4250 (CW = 24.1 mm) eggs respectively. Egg number increased significantly with increase in crab size. This information contributes to our knowledge of the reproductive potential and the reproductive processes occurring in this species of crab.

Autores: Reed, G.
The Marine Environmental Data Inventory (MEDI) is a catalogue system for marine datasets within the framework of the IOC's International Oceanographic Data and Information Exchange (IODE) programme. The development of MEDI was recommended in 1971 by the Joint Task Team on Interdisciplinary and Inter-organizational Data and Information Management and Referral (IMAR). The Sixteenth Session of the IODE Committee recommended (Recommendation IODE-XVI.1) MEDI becomes a permanent program of IODE. A Steering Group was established tasked with the responsibility for the further development and enhancement of the MEDI software tool, in response to user feedback and additional requirements. The MEDI metadata directory is a global inventory of data holdings held in the...

Seychelles tuna fishery bulletin: fourth quarter 1985
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean during the fourth quarter of 1985 increased from 36 in October to 38 in December, about ten vessels less than in the fourth quarter of 1984.  Fishing success during the fourth quarter of 1985 was similar to the third quarter, and slightly better than the fourth quarter last year. Since commercial purse seiner operations began in 1982, catch rates have been high during the first quarter, then have declined progressively during the second and third quarters due to weather conditions of the Inter-Monsoon and the Southeast Monsoon periods.  This year, however, catch rates during the first quarter were low, due largely to bad weather, then remained at roughly the same level for the second quarter,...

Autores: Weisman, R.; Baden, D.G.; Blythe, D.G.; Fleming, L.E.; Bean, J.A.
In addition to increased seafood consumption and tourism, recent studies link global climate change with an apparent increasing incidence of the Marine Seafood Toxin diseases. However, the epidemiology of the human diseases caused by the harmful marine phytoplankton is still in its infancy. In general, the epidemiology of these diseases has consisted of case reports of acute illness, sometimes as epidemic outbreaks, associated with the ingestion of suspicious seafood. Furthermore, even these outbreaks are highly under-reported, especially in poorer countries and in traditionally non-endemic areas. True incidence data are not available due to the lack of disease and exposure biomarkers in humans, as well as the global lack of routine exposure and disease...

Coral Bleaching in the Indian Ocean Islands: Ecological Consequences and Recovery in Madagascar, Comoros, Mayotte and Reunion.
Provedor de dados: 20
Autores: Bigot, L.; Quod, J.P.
During the period from January to August 1998, the largest coral bleaching event and subsequent mortality ever recorded had a huge ecological impact on coral reefs throughout the Indian Ocean. This event corresponded to increased seawater temperatures due to an ENSO phenomenon (Wilkinson, 1998). The full extent of the socio-economic impacts will depend on the recovery capacity of corals which, in many locations, are seriously threatened by human activities. This study documents the ecological status and recovery of corals reefs from theComoros archipelago (Comoros, Mayotte, Geyser), Madagascar and Réunion which were affected by the bleaching from January to August 1998. The impact of the bleaching at each location varies in its extent in time and severity.

Autores: Mwashote, B.M.; Shimbira, W.
Chemical and physical investigations of water on a 10 km section of     the Sondu-Miriu river in Kenya were conducted in 1988-1990. They     revealed no significant spatial variation between three sampling     stations. Variation existed between the waters of a floodpool and the     river. Flooding had a general diluting effect on the nutrients. All     the physical and chemical parameters investigated were within     tolerable limits of water quality according to WHO criteria for     drinking water, fisheries and other aquatic life. A total of 22     phytoplankton and 9 zooplankton genera were recorded. The algae     Microcystis (cyanobacteria) and Navicula (diatom) were dominant. Mean     densities were 283 cells or colonies per ml for phytoplankters and...

The challenges of integrating marine sciences with coastal management in the western Indian Ocean region.
Provedor de dados: 20
Autores: Ngoile, M.
About 30% of the 100 million inhabitants of the western Indian Ocean (WIO) region reside in the coastal strip and are heavily dependent on goods and services provided by oceans and coasts. Coastal areas provide food and resources which support the economies of coastal states of the western Indian Ocean such as fisheries, shipping, petroleum exploitation, seabed mining, energy and tourism. Coastal and marine areas house a bounty of biodiversity and the oceans are also responsible for balancing the extremes of climate conditions. However, our efforts to effectively manage the use of coastal resources in a sustainable manner are constrained by inadequate knowledge in the ecosystems and inadequate capacities to generate the knowledge. This is compounded by the...

Data used to generate the tables and figures presented here are based on daily catch and effort forms (logbooks) returned from fishing vessels that are licensed to fish in the Seychelles EEZ and for purse seiners, as well as from data collected via the tuna sampling programme conducted during transhipment in Port Victoria. Sometimes there are delays in these being received at SFA, especially for longliners that often spend up to a year at sea. For purse seiners the delays are usually during and just after the second quarter of the year when most vessels are fishing in the Mozambique Channel and are not necessarily using Port Victoria for transhipment.  Readers should note that many of the figures presented here are subject to revision (usually upwards) as...

Sand barrier development in the bight of Benin, West Africa
Provedor de dados: 20
Autores: Blivi, A.B.; Anthony, E.J.; Oyédé, L.M.
The morphology, sedimentary facies, stratigraphy and development history of re-entrants and sand barriers in Togo and Benin (West Africa) have been analysed from boreholes and field data, and available radiocarbon dates. Re-entrant deposits range from basal Late Pleistocene fluviatile sands into Holocene estuarine and fluvio-deltaic sands. As sea level stabilized between 6000 and 5500 B.P., the "compartmented" coast associated with these reentrants favoured a polycellular longshore drift system. As the latter became infilled throughout the bight of Benin between 6000 and 4000 B.P., the littoral drift system evolved into a unicellular system fed by the Volta delta in Ghana, which has been the major sand source for an almost 300 kin long outer harrier.

Icing of fish and construction of an iced fish box
Provedor de dados: 20
Autores: Emokpae, A.O.
In many developing countries, coastal fisheries are very important and account for the greater part of fish landings. Because they employ canos, rafts and other primitive crafts. Present developments are concentrated on the small motorized vessels which cover greater arears and land more fish. The preservation of these catches on board and during distribution ashore presents great problems under tropical conditions. The simplest and most desirable solution is the chilling of these catches with ice. This paper describes the use of a new boxing system on board small fishing crafts.

Autores: Okorley, E.L.; Zinnah, M.M.; Mensah, A.O.; Owens, M.
The role of women in food production, processing and marketing has become more relevant as a way of fighting poverty and ensuring food security in Africa. This study was undertaken to assess the state of women in small-scale fish smoking in the Central Region of Ghana. The study involved 150 women fish processors. Descriptive and correlational statistics were used to analyze the data. The findings revealed that the women fish processors were mainly full-time fish processors with a minimum of 10 years experience in fish processing. The women fish processors were generally poor income earners with great responsibility of catering for a large number of dependents. Inadequate capital was the most important constraint for the women fish processors....

The analysis of DNA damage by mean of Comet or single cell gel electrophoresis (SCGE) assay has been commonly used to assess genotoxic impact in aquatic animals being able to detect exposure to low concentrations of contaminants in a wide range of species. The aims of this work were 1) to evaluate the usefulness of the Comet to detect DNA strand breakage in dolphin leukocytes, 2) to use the DNA diffusion assay to determine the amount of DNA strand breakage associated with apoptosis or necrosis, and 3) to determine the proportion of DNA strand breakage that was unrelated to apoptosis and necrosis. Significant intra-individual variation was observed in all of the estimates of DNA damage. DNA strand breakage was overestimated because a considerable amount...

Pirate fishing by vessels flying Flags of Convenience (FOC) has become an issue internationally. They target primarily the high value species, such as shrimp, tuna, squid and others, and will fish anywhere in the world in order to catch them - on the high seas where there are no controls, in coastal waters of States which do not have the means of defending their waters against them. In several fisheries, such pirates are having a serious impact on the stocks, in some cases, it is estimated, making larger catches than the legitimate catches by vessels which participate in proper management regimes.

Estandarización del esfuerzo de pesca ejercido sobre el abadejo (Genypterus blacodes) en aguas Argentinas. Período 1986-1996.
Provedor de dados: 20
Autores: Cordo, H.D.
If the fishing effort is properly standardized, the catch per unit of effort may be proportional to biomass (C/f=q x B(med)). A multiplicative factorial model was applied to the ling Genypterus blacodes catch and effort data by the Argentine bottom trawl fleet recorded between 1986 and 1996. The relative fishing power of the fleet strata was estimated and the effort standardized to obtain normalized CPUEs. Provided they were estimated in the same spatial and temporal situation, there were no differences between the normalized CPUE and the nominal CPUE because ling is caught mainly as by-catch in the Argentine hake fishery. A general picture of the spatial and temporal distribution of ling as reflected by the commercial fleet operations was also obtained.

Autores: Suárez, G.; Romero, T.; Perigo, E.
1 The waste waters of the sugar industry, have constituted the main organic focuses of pollution of the Cuban coastal waters, during the years 1958 to 1991 worked around 160 sugar mill factories with a production average between 3,5 and 8,0 million metric ton sugar cane. During the last years this industry sensibly diminished its activity being considered the production of residual in 70 %, only working 25 % of the factories installed in Cuba, implying certain reduction of the sea impact. This report tries to interpret by means of toxicity bioassays the effects of waste waters of this industry on the survival of the spiny lobster Panulirus argus. Being that the values of LC50 were of 6,7; 5,6; 3,2 and 2,7 % for 24, 48, 72 and 96 h to the contact of...

Metodología para la evaluación de riesgos sanitarios ante la contaminación fecal.
Provedor de dados: 20
Autores: Delgado Gómez, Y.; Miravet Regalado, M.E.
La contaminación fecal es un peligro de origen antrópico que amenaza la zona costera fundamentalmente. En Cuba, los esquemas regulatorios para el control de la calidad microbiológica de las aguas de uso recreativo han estado basados en un único “valor límite permisible” que define si un área es apta o no para el baño (NC 22:99). Sin embargo, esta norma no permite evaluar el nivel de peligro, vulnerabilidad y riesgo sanitario al que se expone la población ante un determinado grado de contaminación fecal, por tanto, en este trabajo se propone por primera vez en Cuba, una metodología que permita evaluar el nivel de peligro, vulnerabilidad y riesgo en una zona marino costera ante la contaminación fecal. Según la concentración de coliformes fecales presente se...

Variación mensual y mareal del zooplancton en una estación fija del estero del Muerto, Golfo de Guayaquil
Provedor de dados: 20
Autores: Arcos, F.; Martínez, L.
Durante los meses de Marzo de 1983 a Febrero de 1984, se llevaron a cabo muestreos de 24 horas consecutivas en las fases llenas lunares en una estación fija en la región interior del Golfo de Guayaquil. Con esta información se han determinado variaciones mensuales y mareales del zooplancton, así como de otros parámetros ambientales, encontrándose una estrecha relación entre la abundancia de organismos y los valores de salinidad. La mayor biomasa planctónica estuvo asociada con los meses secos de alta salinidad. Analizando la variación mareal, se ha determinado que durante las mareas, existe aporte de material nutritivo desde el interior del estuario hacia la región exterior.

El-Max fish farm is one of the most important natural fish farm in Alexandria which is suffering from die-off of large amounts of fish. Facing this problem we must deal with the estimation of the quality of the farm raring unit environment (ponds). Analysis of samples using the Bray - Curtis similarity coefficient test yielded that, the input and El-Khandac were similar at (97%), while the eight ponds were classified at different level of similarity as follows: pond1 (B1) and pond7 (B7) were similar at (86%), B2 and B3 were similar at (90%), B14, B10 and B9 were similar at (93%), where as B11 is singly separated at (83%).

Ocurrencia de gallineta con joroba, Prionotus stephanophrys Lockington (Pisces: Triglidae) en aguas ecuatorianas, y aspectos de su comportamiento, biología y utilización
Provedor de dados: 20
Autores: Herdson, D.M.; Martínez, J.
The occurrence of gurnard Prionotus stephanophrys was studied in the course of a series of fisheries research cruises on the Ecuadorian continental shelf between 1980 and 1985. The species is common in coastal waters south of 1°S . Its abundance is very variable, possibly associated with sea temperatures. Normally densities are between 0.8 and 1.6 t.km-2. The standing stock varies between 13,000 and 150,000 t wich it is estimated can sustain catches of around 4,000 t pet year, and up to 40,000 t in times of great abundance. P. stephanophyrs is found in large shoals on the bottom during the day but a night moves up into mid-water to feed on euphausids. The fish caught had size range of 12 cm to 37 cm, but the majority were between 16 cm and 21 cm in total...

Biodiversity of Estuarine Fish Faunas in West Africa
Provedor de dados: 20
Autores: Baran, E.
In West Africa (between Ivory Coast and Sénégal), estuarine environments vary from lagoons to high discharge rivers to inverse hypersaline estuaries. This results in a high diversity of estuarine fish species, with an important turnover and a core of ubiquitous species. The species richness of a given estuary depends on the combination of hydrological factors (marine or freshwater dominance) and biogeography (continental biogeographic regions). The catch rate is higher in lagoons and inverse estuaries than in normal estuaries, which can be explained by the predominance of small juveniles in the latter. Clupeids are the most abundant fishes all over the region, but different systems have different dominant species. Assessing the functioning of West-African...

Estimación de un índice de abundancia anual de gatuzo (Mustelus schmitti) a partir de datos de la flota comercial argentina. Período 1992-2008
Provedor de dados: 20
Autores: Pérez, M.; Massa, A.M.; Cordo, H.D.
Patagonian smoothhound (Mustelus schmitti) is one of the predominant cartilaginous fishes of the Argentine Sea (SW Atlantic Ocean). It is caught, mainly, in the coastal multispecific fishery with nearly other 30 bony and cartilaginous species. The group is known as ‘variado costero’. In this work the smoothhound abundance indices (CPUE) and standardized efforts for the 1992-2008 period in the area between 34~’S-42~’S were estimated. The General Lineal Model (GLM) and data derived from the argentine commercial fleet were used. Other aspects that could affect estimates and trends of the annual indices were also analyzed. Mean CPUE values estimated with the GLM, considered as annual standardized abundance indices, show an increasing trend as of 2000; the...

This work deals with the structure and efficiency of the fleet fishing white croaker in Argentina. Results show that there exist two strata delimited by 17.25 m length and 345 HP vessels. The most efficient is constituted by those of smaller dimensions. During 1992-1995 landings were sampled and subsequently analyzed. A decrease in mean length landed and  an increase of juveniles presence were detected. The situation coincided with an increment of catches, landings, fishing effort, exports and the fleet activities in "El Salado" area (35° 57' - 36° 57' LS).

El Instituto Oceanográfico de la Armada (INOCAR) mantiene desde 1990 hasta la fecha una estación costera a 10 millas náuticas frente a las costas del puerto de La Libertad (Península de Santa Elena), en la que se efectúa un muestreo de toda la columna de agua desde la superficie hasta los 100 m de profundidad, cada 20 días. Del análisis preliminar se ha podido observar que la distribución de las isotermas responde a la presencia de los eventos ENOS; como se conoce durante un episodio ENOS la costa del Ecuador es visitada por ondas ecuatoriales, las cuales a su paso producen una elevación del medio del mar  y una profundización de las isotermas. Por lo que se considera que esta distribución de las isotermas guarda relación con la ocurrencia de los eventos...

The freezing raw whole lobster is one of the products that are commercialized in the outer market; nevertheless the main factor that causes its rejection is the mass texture. Nodarse et al. (2005) determined that this product stayed with very good characteristics for its exportation until 10 months, after this period it began to detect a softening of the mass. There are different methods to determine the food texture, which is grouped in sensorial and instrumental. The objective of the present work was to determine the sensorial and instrumental texture of this product. Five raw whole lobsters by duplicate with different time storage (6, 8, 10, 12, 14 months) were evaluated using for it a paired comparison test. In order to measure the product firmness. It...

Oceanografía física del estuario del Río de la Plata y el sistema costero de El Rincón. Noviembre, 1994
Provedor de dados: 20
Autores: Guerrero, R.A.
Using the CTD data obtained on the R/V Dr.E.L.Holmberg fishery research cruise H-13/94 (November 1994), oceanographic conditions of the coastal area of the Argentine-Uruguayan Common Fishing Zone (AUCFZ) and El Rincón (Buenos Aires Prov., Argentina) are described. Two physical environments were differentiated: the Río de la Plata estuarine systems and El Rincón coastal regime. In both systems thermal and haline fronts that affect the distribution of reproductive concentrations, nursery and spawning areas of coastal species, are identified. Salinity fields of the AUCFZ, as a function of statistical winds, are synoptically analyzed. In El Rincón, the temporal stability observed on temperature and salinity allowed to describe the mean physical conditions for...

Seychelles tuna bulletin: Year 2009
Provedor de dados: 20
Data used to generate the tables and figures presented here are based on daily catch and effort forms (logbooks) returned from fishing vessels that are licensed to fish in the Seychelles EEZ and for purse seiners, as well as from data collected via the tuna sampling programme conducted during transshipment in Port Victoria. Sometimes there are delays in these being received at SFA, especially for longliners that often spend up to a year at sea, and for purse seiners the delays are usually during and just after the second quarter of the year when most vessels are fishing in the Mozambique Channel and are not necessarily using Port Victoria for transshipment.

Variaciones verticales y su relación con algunos parámetros físico-químicos en una estación fija en el área externa del Golfo de Guayaquil
Provedor de dados: 20
Autores: Chiriguaya, J.; Burgos, L.
Las variaciones hidroquímicas (oxígeno disuelto, nitrato, fosfato y silicato) fueron estudiadas durante 12 horas con intervalos de aproximadamente 3 horas en una estación fija situada frente al Golfo de Guayaquil entre las coordenadas 02° 59' 42 S-81° 40' 92 W. La máxima profundidad en la que se efectuó dicho análisis fue hasta los 50 metros. Se ha detectado una posible relación entre las variaciones verticales (Ondas Internas) y los parámetros físico-químicos, ya que las fluctuaciones de ascensos y descensos fueron observadas en las concentraciones de oxígeno y nutrientes, siendo las ondas internas un factor preponderante en los movimientos verticales de éstos. Estas fluctuaciones también fueron encontradas en el comportamiento de la temperatura,...

Autores: Herrmann, Thora M.; Bingham, Mike.
Magellanic penguins (Spheniscus magellanicus) are only found around southern South America, with breeding populations in Chile, Argentina and the Falkland Islands (Malvinas). One of Chile’s largest and most important Magellanic penguin breeding sites is situated on Magdalena Island in the Straits of Magellan. The island has been designated a national nature reserve because of its importance as a penguin breeding site, and the reserve is managed by the government agency Corporación Nacional Forestal. The island is a popular tourist destination, and Magellanic penguins are increasingly exposed to human activities. In order to protect this seabird and to ensure the sustainable use of the reserve as a tourist resource, Magdalena Island has been part of a...

Economic Constraints to the Management of Marine Protected Areas
Provedor de dados: 20
Autores: Tessema, Y.; Emerton, L.
Eastern Africa contains an extensive network of marine protected areas (MPAs), stretching from the Red Sea states of Sudan, Eritrea and Djibouti, along the Indian Ocean coastline of Somaliland, Somalia, Kenya, Tanzania and Mozambique, and out to the Indian Ocean islands of Seychelles, Comoros, Réunion, Mauritius and Madagascar. Most of these MPAs have been gazetted because they contain species or habitats of particular interest, importance or conservation concern that are under threat in some way. The main threats to Eastern Africa’s MPAs arise from human economic activities. These include over-fishing and destructive fishing techniques (such as poison fishing, dynamite fishing and the use of small-mesh nets), the over-harvesting of other marine products...

Geochemical and environmental studies of recent marine sediments and some hard corals of Wadi El-Gemal area of the Red Sea, Egypt
Provedor de dados: 20
Autores: Madkour, H.A.
The distribution of (Fe, Mn, Zn, Cu, Pb, Ni, Co and Cd) concentrations were determined in surface marine sediments and coral reefs at Wadi El-Gemal in the Red Sea area. There were significant differences in concentrations of heavy metals in the marine sediments relative to the coral reefs. Some heavy metal concentrations in sediments and coral reefs in the study area are high compared to that in the impact areas of the Egyptian Red Sea coast. The results indicate that the high concentrations of heavy metals in marine sediments and coral reefs are particularly affected by the high contribution of terrigenous materials through the stream of Wadi El-Gemal. Generally, heavy metals concentration in the sediments decreased with increasing distance from the...

Autores: Gregorio, C.G.; D'Attellis, C.E.
Based on the Schaefer production model, an stochastic model is described, that is a model in which noises perturbing biomass and measurements are considered, serving to describe random variations in mortality and recruitment as well as some inaccuracies in measurements taken. The model is discrete, linear and adaptable, and the parameters biomass and noises intensities are restimated with each new measurement obtained. The problem of regulation is solved, on the basis of the model described, through fishing effort that should be applied to keep biomasss close to equilibrium. Computer effected simulations are presented.

Une étude réalisée au niveau du secteur nord et est de la lagune de Bizerte a montré que les densités et les biomasses totales et individuelles des nématodes libres marins sont étroitement dépendantes des paramètres physico-chimiques, sédimentologiques et géochimiques. En effet, les sédiments de ce secteur ont présenté en surface un faciès très fin enrichi en carbone organique, issu principalement des rejets domestiques et industriels des villes avoisinantes. Ceci favorise la formation de complexes organo-minéraux entre les particules minérales, essentiellement entre la smectite et les composés organiques. Les nématodes libres marins réagissent à ces conditions de surface non favorables par leur migration en profondeur, les individus détritivores étant...

Lors de cette période, une série d'actions a été menée, visant à la lutte contre les végétations flottantes en lagune Ebrié. Les résultats obtenus sont importants, bien que l'on puisse reprocher à ces actions un certain manque de coordination. Le bilan peut être fait ainsi: le suivi des différentes phases d'envahissement indique bien que la cible principale est désormais la jacinthe d'eau (Eichhornia crassipes). L'espèce Pistia stratiotes, endémique, ne constitue pas une véritable menace. S. molesta, qui a été menaçante, reste actuellement cantonnée à quelques zones oligohalines de la lagune Ebrié, la concurrence de la jacinthe d'eau ayant fortement réduit son extension en zones dulçaquicoles.

This dissertation analyses the oceanic circulation of the Norpatagonian Gulfs, a region of the Argentinean Sea that has long been recognized for the high productivity and biodiversity of the ecosystem. The study aims towards a systematic exploration of the physical processes that control the circulation using a high resolution three dimensional numerical model. To facilitate the dynamical understanding of the results our experimental strategy was to start with a constant density (barotropic) model forced by tides and winds, and to progress to a more complex case including density stratification generated by surface fluxes of heat and humidity. The main result that stems from the numerical experiments is that tidal forcing significantly contributes to the...

Autores: Pineda, S.E.; Hernandez, D.R.; Brunetti, N.E.; Jerez, B.
Morphological characters of two loliginid squids, Loligo gahi and Loligo sanpaulensis, in the SW Atlantic region off Argentina were studied to obtain a diagnostic criterion for their identification. Emphasis was placed on the taxonomic characters suitable to identify individuals in the whole size range. Considering the uncertainty associated to the correct identification of juveniles, their taxonomic status was confirmed using electrophoretic studies. Discrimination between species based on morphological characters proved to be more effective than meristic counts. A discriminant function that allows an easy separation of the two species is presented. The function, composed of two indices: fin width mantle length (FW/ML)and gladius width mantle length...

The Blue Plan scenarios, published in 19891, showed that the protection of the Mediterranean Sea, its shores and coastal regions, could not be achieved through action carried out on the sea or on the coastal regions alone. On the contrary, it depended mainly on the overall development, environment and physical planning policies followed by the Mediterranean countries at the national level. “ Decisions on the bulk of environmental protection will be made (or not) largely at the level of the state. Essential legislation and standards will have to be established at this level, as well as the necessary mechanisms and institutions with the financing and competence to apply them... ”. The Blue Plan then invited the neighbouring countries to change direction and...

Guide to operational procedures for the collection and exchange of oceanographic data (bathy and tesac)
Provedor de dados: 20
All nations are profoundly influenced by the world oceans in many ways - some direct and obvious, others indirect and more subtle. Even those countries without ocean coastline feel the influence of the ocean, for example, as it affects world-wide weather and climate and In the availability of foreign goods and access to distant markets. Some influences of the ocean are benefitial; others may be detrimental to human activities ; most are beyond our ability to control, except in very limited ways, but, forewarned with a knowledge of the state of the ocean and even a limited prediction of future trends, it may often be possible to maximize the beneficial effects and to avoid or guard effectively against those which could be detrimental. The Integrated Global...

Conservation of Coral Reefs after the 1998 Global Bleaching Event
Provedor de dados: 20
Autores: Hayes, R.L.; Goreau, T.J.; McClanahan, T.R.
Large-scale coral bleaching has happened repeatedly in the Pacific and Indian oceans and the Caribbean since 1982. Previously it was observed only on a small scale (Williams and Bunkley- Williams 1990;Jokiel &amp; Coles 1990; Glynn 1988, 1991; Goreau et al. 1993; Goreau &amp; Hayes 1994, 1995). The 1998 bleaching event was globally the most extensive such event recorded except in the Caribbean and Central Pacific where a comparison of year-byyear temperature and bleaching maps show that it was comparable with the largest previous events (T.G. et al., unpublished data). Global analyses of coral bleaching are rare, but critical to an understanding of the widespread ecological effect of bleaching events.

Molecular Indicators of the Supply of Marine and Terrigenous Organic Matter to a Pleistocene Organic-Matter–Rich Layer in the Alboran Basin (Western Mediterranean Sea)
Provedor de dados: 20
Autores: Rinna, J.; Hauschildt, M.; Rullkötter, J.
The organic matter in sediment series across two organic-matter–rich layers from Ocean Drilling Program Hole 977A drilled in the Alboran Basin of the Western Mediterranean Sea has been characterized by organic geochemical methods. Organic carbon contents reached more than 2% in the organic-matter–rich layer and was ~1% in the background sediment under and overlying it. Molecular compositions of the extractable bitumens in the organic-matter–rich layer for a wide range of compound groups are broadly similar to those of the background sediments. The organic matter in the organic-matter–rich layer is enriched in marine biomarkers, especially long-chain diols and keto-ols and particularly sterols. A higher supply of landderived material to the sediment during...

This paper reviews the experience and status of coastal aquaculture of seaweeds, mollusks, fish and crustaceansin eastern Africa and the islands of the western Indian Ocean. In many respects, coastal aquaculture is still in itsinfancy in the region, and there is a pressing need toformulate development strategies aimed at improving theincome and assuring the availability of affordable protein tocoastal communities. This paper also draws from positive and negative experiences in other parts of the world. Therequirements of feed and fry, and the conversion ofmangroves are used to illustrate how some aquacultureactivities constitute a net loss to global seafood production.The paper presents both general and specific sustainability guidelines based on the...

Autores: Osumo, W.
Lake Victoria is the second largest freshwater body in the world by surface area. It is important for the livelihood of people living in the area. The lake is currently facing many problems, one of which is macrophyte encroachment mainly the water hyacinth, Eicchornia crassipes. Winam Gulf is a large inlet from Lake Victoria that extends into Kenya. In order to study the effects of water hyacinth on water quality in the gulf, measurements of water properties were made in the north-eastern corner of the gulf, when the area was covered with hyacinth in March 2000. The hyacinth was then cut and dumped on the bottom during the period June to beginning of August when all water hyacinth had been removed with measurements being made again in July. Water...

Autores: Perrotta, R.G.; Hernandez, D.R.
The temperature that limits the presence of schools of Argentine chub mackerel Scomber japonicus was found to be around 19°C in the Mar del Plata area Buenos Aires prov., Argentina. At higher values, most shoals leave coastal waters in direction to the mid-shelf. An inverse relationship was observed between catches per unit of effort CPUE and sea surface temperature. The highest CPUE values corresponded to temperatures lower than 19°C. Beyond that value, the possibility of obtaining a CPUE higher than the unit is nearly null and the low standard deviation means it is unlikely to reach high CPUE values. The economic profit per minute of each daily cruise was estimated using a case study carried out with a single vessel pilot with mean structural and...

The pollution of marine sediments by trace elements in the coastal region of Togo caused by dumping of cadmium-rich phosphorite tailing into the sea
Provedor de dados: 20
Autores: Gnandi, K.; Tobschall, H.J.
The marine coastal sediments irom Togo have been analysed for the trace elements Cd, Cr, Cu, Ni, Pb, Sr, V, Zn and Zr to ascertain the geoecological impact of dumping of phosphorite tailings into the sea. Trace element concentrations ranged from 2-44 ppm for Cd, 22-184 ppm for Cu, 19-281 ppm for Ni, 22-176 ppm for Pb, 179- 643 ppm for Sr, 38-329 ppm for V, 60-632 ppm for Zn and 18-8928 ppm for Zr. Regional distribution L of trace elements in the marine environment indicates that the concentrations of Cr, Cu, Ni, Pb, V, Sr and Zn increase seawards and aloug the coastal a line outwards of the tailing outfall, whereas Cd and Zr showed reversed spatial patterns. Sorting and transport of phosphorite particles by coastal currents are the main factors controlling...

Illegal Fishing in Seychelles
Provedor de dados: 20
Seychelles has extensive pelagic resources and other specific species such as sharks, demersal species, tow spotted red snappers, green job fish, spankled emperor and grouper, etc., not to mention an abundance of sea cucumbers that are not yet exploited. With an EEZ of 1.4 million sq km making the ocean surface 3019 times larger than the land area, it is not surprising that other foreign fishing vessels engage in illegal fishing in Seychelles’ territorial waters, due to the absence of a relevant monitoring, control or surveillance unit.

La ferme de l’AQUALAMA Besalampy est confrontée à un problème de mue des juvéniles de crevettes Penaeus monodon durant leurs transfert du bassin de pré-grossissement vers les bassins de grossissement. Le pourcentage des crevettes molles dépasse le seuil 10% durant la pêche. On est obligé alors d’arrêter le transfert et de le rapporter à un autre jour. L’arrêt fréquent du programme de transfert perturbe le planning déjà établi par la société. Afin d’essayer de trouver les raisons qui déclenchent spontanément la mue des juvéniles, on a effectué le suivi des paramètres physico-chimique de l’eau (pH, température, salinité, oxygène dissous, profondeur de l’eau, les marées, la gestion d’eau,…) durant l’élevage et durant le transfert.

L’engraissement du thon rouge a connu un regain d’intérêt depuis le boom économique japonais i.e. vers le milieu des années 70. A cette époque les projections ont mis en évidence que la production mondiale ne suffirait plus à satisfaire le marché japonais. C’est ce constat qui a amené les grandes firmes japonaises à réfléchir sur l’engraissement du thon rouge. Cette technologie fût exportée en Espagne où l’activité a démarré effectivement au début des années 1990 pour atteindre son apogée vers les années 1996-1997. Plusieurs pays méditerranéens ont suivi le pas de l’Espagne à l’image de la Croatie, Malte, Chypre, Italie, etc., En Tunisie, pendant les six dernières années (2003-2008) l’activité d’engraissement du thon rouge (BFT) a atteint voire dépassé...

Seychelles tuna bulletin : third quarter 1988
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean during the third quarter of 1988 increased from 38 at the end of the second quarter to 43 in July, reaching a maximum of 46 in September.  This represents a considerable increase in the number of active vessels compared to the same period last year when a maximum of 38 vessels were in operation in September. Overall catch rates increased from 19 MT/day during the second quarter of 1988 to 25 MT/day during this quarter, reaching the same level as in the previous year.  The proportion of yellow fin dropped from 53% in July to 17% in September with a corresponding increase in skipjack catches.  This fishing pattern follows the same trend set in previous years, as vessels fished around the Equator...

Use of Genetically Improved and Alien Species for Aquaculture and Conservation of Aquatic Biodiversity in Africa
Provedor de dados: 20
Starting from a small base, aquaculture production in Africa registered annual growth rates equal to or above those in other regions. This expansion was due to signifi cant increases in a few African countries. Increasing demand coupled with rapidly dwindling catches from capture fi sheries, the implementation of novel participatory approaches to technology development and transfer, and the emergence of a few successful large-scale tilapia culture operations directed at the export market offer opportunities for further expansion in both the small-scale and large-scale commercial sectors. Existing biotechnical, economic and institutional challenges, which include lack of national policies to guide aquaculture development, unfriendly investment policies, the...

Based on the comparison between length composition of landings and that of research cruises, filtered by the selectivity of the mesh used by the commercial fleet, to rebuild length distribution of catches, an indirect quantitative method was developed and used to estimate, in weight and number, the individuals discarded by the commercial fleet south of 41° S. Discards ranged between 15,563 and 46,113 annual tons in the 1986-1993 period which represented 10-13% in weight and 28-32% in number of actual catches, composed of around 87% of individuals age group 1, 12% of age group 2 and the rest of individuals age groups 0 and 3.

Provedor de dados: 20
Autores: Oladosu, H.A.; Ayinla, O.A.; Ajiboye, M.O.; Egbomuche, G.; Onuoha, G.C.
An upsurge in the prevalence of rusty-yellow discoloration of the skin of the two tilapia species, being cultured at the African Regional Aquaculture Centre (ARAC), gave a basis for an urgent clinical and epizootiological studies of the condition.  The studies were therefore carried out along with the performance of some catfishes in polyculture with Oreochromis niloticus, under the integrated poultry cum fish farming system. It was observed that this condition affects the tilapia species only, and the antemortem, and postmortem examination revealed that the discolouration is restricted to the surface of the cutaneous tissue; affecting the underside of the exposed part of the scales, the fins and the skin flap covering the scale pockets, mostly in adult...

Biologie et exploitation du poulpe Octopus vulgaris (Cuvier, 1797) des côtes mauritaniennes
Provedor de dados: 20
Autores: Dia, M.A.
L’étude porte sur l’exploitation, la biologie et la dynamique du poulpe (Octopus vulgaris, Cuvier) des eaux mauritaniennes. La répartition spatio-temporelle dans la région du Cap Blanc ne semble être liée ni à la taille, ni au sexe, mais varie au cours de l’année. L’analyse de l’état actuel de la pêcherie basée sur les congélateurs céphalopodiers met en évidence une augmentation de l’effort de pêche et la poursuite de chute des p.u.e. La composition des captures révèle une progression du pourcentage des individus de poids inférieur à 200 grammes (« poulpo »). L’étude biologique montre qu’il existe deux saisons de reproduction par an (mai-juillet et septembre-novembre) qui engendrent deux recrutements, l’un en mai et l’autre à partir de septembre. La...

Repair of UVB-Damaged Skin by the antioxidant sulphated flavone glycoside Thalassiolin B Isolated from the marine plant Thalassia testudinum Banks ex König
Provedor de dados: 20
Autores: Regalado, E.L.; Rodríguez, M.; Menéndez, R.; Concepción, A.A.; Nogueiras, C.; Laguna, A.; Rodríguez, A.A.; Williams, D.E.; Lenzo-Luaces, P.; Valdés, O.; Hernandez, Y.
Daily topical application of the aqueous ethanolic extract of the marine sea grass, Thalassia testudinum, on mice skin exposed to UVB radiation resulted in a dose dependent recovery of the skin macroscopic alterations over a 6-day period. Maximal effect (90%) occurred at a dose of 240 μg/cm2, with no additional effects at higher doses. Bioassay-guided fractionation of the plant extract resulted in the isolation of thalassiolin B (1). Topical application of 1 (240 μg/cm2) markedly reduces skin UVB-induced damage. In addition, thalassiolin B scavenged 2,2-diphenyl-2-picrylhydrazyl radical with an EC50=100 μg/ml. These results suggest that thalassiolin B is responsible for the skin regenerating effects of the crude extract of T. testudinum

Genetic Differentiation in West African Lagoon Fishes
Provedor de dados: 20
Autores: Agnese, J.F.
Most of the fishes living in the lagoons do not spend all their time in these brackishwaters. Sometimes, they go back to the river to spawn as in the case of freshwater fishes like Chrysichthys nigrodigitatus. Others like marine fishes (e.g., Ethmalosa jimbriata) feed or reproduce in lagoons for a time. Even true lagoon fishes are generally able to live in freshwater and/or in marine water. This is the case for two brackishwater tilapias, Sarotherodon melanotheron and Tilapia guineensis. Both are present in lagoons from Senegal to Congo (formerly Zaire). S. melanotheron is present in marine water near Dakar, Senegal, and in some freshwater lakes in Cote d'Ivoire. 1: guineensis is also present in freshwater in Cote d'Ivoire.

Definición de los requerimientos nutricionales de juveniles y pre-adultos de la langosta de agua dulce Cherax quadricarinatus, con especial énfasis en la realidad proteína/lípido
Provedor de dados: 20
Autores: Cortés, E.
El cultivo del acocil (crayfish) del género Cherax, también conocido como langosta de agua dulce, ha recibido atención considerable entre los productores acuícolas y agrícolas en México, debido a sus características biológicas y a la necesidad de considerar especies alternativas para la producción acuícola. Una de las limitaciones importantes para el éxito del cultivo comercial de Cherax quadricarinatus ha sido la falta de información apropiada en los aspectos nutricionales y las prácticas alimenticias de la especie. Se realizaron cuatro evaluaciones experimentales para determinar los requerimientos en proteína y lípidos de la especie en las fases de juveniles y pre-adultos, así como la frecuencia alimenticia óptima. El requerimiento de proteína para...

An approach to estimate tidal dissipation with single-point high-frequency ground wave radar data.
Provedor de dados: 20
Autores: Mao, Huabin; Chen, Ju; Qiu, Chunhua; Lian, Shumin.
Using the single-point ground wave (GW) radar data at Shensi Station and the water level data at three stations (Shengsi, Luchaogang and Daishan), the authors obtained the flow vectors from the radial velocity of GW radar observation, and calculate four sub-tidal harmonic constants (O1, K1, M2 and S2). The tidal characteristics derived from the GW radar dataset agreed well with those from the tidal gauge data. The authors also analyzed the tidal energy flux and tidal energy dissipation rate. There was a good relationship between the tidal energy dissipation rate and topography. The study showed a good way to calculate tidal energy dissipation rate using GW radar data.

The skeletal growth of the scleractinian corals Diploria labyrinthiformis (Linnaeus 1758) and Montastraea annularis (Ellis and Solander 1786) from Isla Grande (north of Rosario islands), Colombian Caribbean, was determined from annual extension increments revealed by X-radiography of 4-6 mm thick slabs obtained along the axis of maximum growth. The skeletal extension average rate for the last 22 years for D. labyrinthiformis was 3.8 mm year-1 (SE 0.10; N = 87). The correlation between growth of D. labyrinthiformi s and hours of sunlight was significantly negative. The annual variances of sunlight enhanced annual statistically significant differences of growth in this species. M. annularis showed an average extension growth of 10.6 mm year-1 (SE 0.32; N =...

Le poulpe commun, Octopus vulgaris Cuvier, 1797 est une espèce clé dans l'économie des productions halieutiques au Sénégal, suite à une intrusion massive et une explosion démographique dans les eaux marines de ce pays, depuis les années 80. Pour expliquer le phénomène, on a estimé intéressant de connaître la place de l'espèce dans l'écosystème local par le biais de ses relations trophiques avec le milieu naturel. Au cours de prospections effectuées, de 1996 à 1998 inclus, sur le terrain et grâce à des séjours en mer, lors de campagnes chalutières, 459 O. vulgaris ont été récoltés. Leurs contenus stomacaux ont été analysés selon des méthodes classiques, qualitatives et quantitatives. O. vulgaris se nourrit régulièrement, toute l'année, d'organismes...

Toxin composition of three species of marine gastropods Zidona angulata, Adelomedon brasiliana and Pachycymbiola brasiliana and the mussel Mytilus edulis, and an Alexandrium tamarense isolate (AMI)from the Mar del Plata coast, were determined by means of a sensitive and specific HPLC technique. Cultures of A. tamarense contain N-sulfocarbamoyl derivatives as major toxins. The next most abundant components were GTX1 neoSTX and GTX4. As minor components, unusual decarbamoyl toxins were detected. Saxitoxin was the lowest of the 10 detectable toxins. Comparison of toxins profiles revealed significant differences between the toxic composition of the dinoflagellate and that accumulated in the tissues of their primary and secondary consumers. In the mussel M....

The fisheries policy of the Republic of Seychelles
Provedor de dados: 20
Autores: Anon.
The fisheries policy of the Government of Seychelles was first drafted in 1986. At that time, both the industrial and artisanal fisheries in Seychelles were in a developmental stage and the policy reflected the needs to promote both the development and conservation of our marine resources as well as maximizing benefits. In 1985 the number of licenses issued for the industrial tuna fishery was 49 for the purse seiners and 165 for longliners with an annual purse seine catch of 130,000 tonnes. The total catch for the industrial purse seine fishery has continued to rise and peaked at around 407, 000 tonnes in the year 2003. The artisanal fishing fleet has declined from 410 vessels in 1985 to 330 in the year 2003, however, the nature of the fleet has changed...

The equation log W=a+bL (where W=dry weight in ug, and L=total length in mm)was used to describe the growth in weight of larval anchovy collected in two areas of the Argentine sea, sampled in different months and several years. Regression lines were compared by covariance analysis applied to two size groups, namely larvae less and over 10 mm total length, as an evident break in the slopes indicated the existence of a chenge of rythm in the trajectory of larval growth in length. Significant differences between the slopes of the growth lines were observed within the smaller size group. No regional or yearly differences could be established fo larvae larger than 10 mm.

Spatial and temporal distribution of reef fish spawning aggregations in the Seychelles – an interview-based survey of artisanal fishers
Provedor de dados: 20
Autores: Öhman, M.C.; Isidore, M.; Payet, R.J.; Robinson, J.; Marguerite, M.A.
Many coral reef fish species aggregate at specific times and locations for the purpose of spawning. This study examined the spatial and temporal distribution of spawning  aggregations in the Seychelles. An interview-based survey of the principal stakeholders, mainly artisanal fishers, yielded 89 reports of aggregation fishing for 26 demersal and semi-pelagic fish species. Grouper aggregations were largely concentrated in the outer coralline islands of the exclusive economic zone, whilst those of snappers and rabbitfishes were mainly reported from locations on the Seychelles Bank. The spatial patterns among fish families were attributed to a combination of differences in species abundance and distribution as well as variation in fishing effort. Spawning...

La esponja marina Discodermia dissoluta es fuente del policétido discodermólido, un potente antitumoral que ha alcanzado fase clínica con pruebas en humanos. En Santa Marta esta especie se encuentra a menor profundidad en comparación con otras áreas del Caribe y por ello se pudieron estudiar por primera vez y por medio de buceo autónomo sus características ecológicas, abundancia y distribución. Haciendo recorridos por la base de los arrecifes (12-25 m de profundidad), se determinó que esta especie se restringe a sitios relativamente protegidos del oleaje y vive predominantemente en sustratos duros horizontales a inclinados, en general expuestos a la luz. Censos realizados a partir de círculos de 4 m de radio mostraron densidades moderadas de unos 2-5...

Long-term Trends in Coral Reef Fish Yields and Exploitation Rates of Commercial Species from Coastal Kenya
Provedor de dados: 20
Autores: Kaunda-Arara, B.; Rose, G.A.; Muchiri, M.S.; Kaka, R.
Analysis of long-term (1978–2001) marine fisheries data showed that Kenyan coralreefs produced an estimated 2–4 metric t/km2/year of demersal fish. A rapid overall decline in landings occurred during the 1990s. Yields (t/km2/year) showed bimodal peaks in 1982 (2.98) and 1991 (2.90). The average total landings dropped by 55% during the last decade following peak landings in 1982. Landings of the commercially important families (e.g., Siganidae, Lethrinidae, Lutjanidae and Serranidae) declined by about 40% during the last decade, with the groupers (Serranidae) showing the steepest (72%) decline. Analysis of landings per administrative district showed a 78% decline in the densely populated Mombasa district between the periods 1983–1991 and 1992–2001. The less...

Nutritional Studies and Development of a Practical Feed for Milkfish ( Chanos chanos) Culture in Zanzibar, Tanzania
Provedor de dados: 20
Autores: Jiddawi, N.S.; Mwangamilo, J.J.
A study was conducted to find a suitable diet and feeding level for the culture of milkfish (Chanos chanos) in Zanzibar. Two growth trials and one digestibility trial were done. The first growth trial was conducted using 25, 32 and 40% protein diets to determine the optimal level that could be used for the second growth trial on feeding levels. There were no significant differences on feed intake and growth performance of milkfish among the treatments (P&lt;0.896). Body composition analysis showed that fish had more fat (lipid) when fed 32 than 25 and 40% protein diets. The digestibility of protein increased with increasing protein levels: it was 87.3, 92 and 93% respectively. There were no significant differences among the diets (P&lt;0.291). The 32%...

Remote Sensing for Studying Nearshore Bottom Morphology and Shoreline Changes
Provedor de dados: 20
Autores: Shaghude, Y.W.
The major objective of the present study is to demonstrate how remote sensing approach can be used for studying nearshore bottom morphology and shoreline changes in coastal Tanzania. Two study sites were used. In the first site, remote sensing satellite Landsat Thematic Mapper data was evaluated against known water depths from conventional echo sounding measurement taken on the eastern side of the channel. The correlation between the remote sensing data and the echo sounding mesurement was rather satisfactory, suggesting that the approach can roughly be used to investigate sea bottom morphology in the nearshore areas. In the second study site, remote sensing satellite data from Landsat Thematic Mapper and Enhanced Thematic Mapper were used to investigate...

IODE involvement in MarineXML began in 2000 with establishment of the marineXML consortium by the previous IODE chair, Ben Searle. This was based on the model of OGC with members making financial contributions in return for voting rights on standards development proposals. This model was not widely accepted by the oceanographic community and the Consortium Secretariat was transferred into the IODE Secretariat in 2002. This initial consortium was replaced by two initiatives. The partners in the consortium formed the core of a successful bid to the European Commission for a project to demonstrate oceanographic data interoperability using an XML-based solution.

Benefits Beyond Boundaries: Fishery Effects of Marine Reserves
Provedor de dados: 20
Autores: Roberts, C.M.; Gell, F.R.
Marine reserves are areas of the sea where fishing is not allowed. They provide refuges where populations of exploited species can recover and habitats modified by fishing can regenerate. In some places, closed areas have been used for fisheries management for centuries, and until recently natural refugia also existed, inaccessible through depth, distance or adverse conditions. Developments in technology have left few areas beyond the reach of fishing. Recently, the idea of marine reserves as fisheries management tools has re-emerged, developing from ecosystem management approaches, and observations of incidental fisheries benefits from reserves established for conservation. Marine reserves are predicted to benefit adjacent fisheries through two...

The Influence of Pacific SST on the Precipitation over Southern Africa Diagnosed from an AGCM
Provedor de dados: 20
Autores: Misra, V.
This study is an analysis of AGCM model results to understand the dynamics of the response of precipitation over southern Africa (SA) to anomalies in the sea surface temperature (SST) over the Pacific Ocean. The dipole pattern of interannual precipitation anomaly over SA and its temporal variations are quite similar in both the ensemble mean of the control (where the AGCM is forced with observed SST’s in all ocean basins) and experimental runs (where the AGCM is forced with seasonally varying climatological SST over the Pacific Ocean). However the amplitude of the variability is found to be relatively reduced in the experimental runs. This is shown to be a result of the modulation of the Walker circulation by the variability of Pacific Ocean SST. The...

Understanding and predicting the interannual variations of the whole monsoon climate system has been, and will continue to be, one of the major reasons for studying the oceanography of the Indian Ocean; but there are other reasons. Knowledge about Indian Ocean current systems may have diverse practical applications, from fisheries through search and rescue to management of Exclusive Economic Zones. Our discussion mainly concerns the open ocean and the climate applications, but the results are important for most continental shelves of the Indian Ocean region on all but the shortest timescales. We start by discussing what we know now of the Indian Ocean’s mean annual cycle, painfully gleaned from sparse observations over the last four decades. This data base...

Autores: Kimani, E.N.
Coral reefs are a prominent feature of the East African coastline and associated islands. The Kenya-Tanzania coastline stretches from 1°30'S, at the Somali border to approximately 10°S at the Mozambique border. The Seychelle Islands extend from 5°S to 10°S and 45°E to 56°E (Fig. 1). The climate along the East African coast is dominated by seasonal monsoon winds (northeast monsoon from No-vember to February and southeast monsoon from March to October) and the equatorial currents dictated by the intertropical convergence zone. The narrow East African continental shelf supports fringing and patch reefs which lie 0.5 to 2 km offshore. General profiles of East African coasts are given in Table 1. Gaps in the reefs occur near river mouths notably Tana, Athi and...

Enforcement In Kenya’s Marine Protected Area Network
Provedor de dados: 20
Autores: Muthiga, N.
The Kenyan coastline is approximately 500 km long, with a well developed fringing reef system except where major rivers (Tana and Athi Sabaki) discharge into the Indian Ocean (Hamilton and Brakel, 1984). Additionally patch reefs occur in Malindi and Kiunga in the north and Shimoni in the south on the Kenya Tanzania border (Fig. 1). Coral reefs are the predominant marine ecosystem in terms of ecology and economy but seagrass beds and mangrove forests also contribute to the economy of the coastal communities ( Muthiga ITMEMS). The coastal topography, climate and habitats of the Kenyan coast have been described in McClanahan 1988, McClanahan and Young 1986, Obura et al 2000). In order to conserve and manage these important ecosystems, the government of Kenya...

Manual of Marine Meteorological Observations, Eighth edition.
Provedor de dados: 20
The Conference of Brussels, called in 1853, was the first International Maritime Conference ever held. It sponsored the idea that Governments should foster systematic weather observations on ships, and should prepare and publish charts of the prevailing winds, ocean currents, average sea and air temperatures, and tracks of dangerous storms based on the additional data. With the introduction of radio and fast ships, weather information became of vital importance to safe and efficient ship operation. Many countries began regularly scheduled weather forecasts to ships in nearby waters. Today, weather forecasts as well as charts arc prepared from data collected through ship observations. Forecasts of weather and sea conditions arc prepared for ship operation,...

Marine invertebrate communities of Baie Ternay National Marine Park and Baie Beau Vallon, Mahe, Seychelles
Provedor de dados: 20
Autores: Pittman, S.J.
Typically, coral reefs are dominated by sedentary colonial organisms. Species compositions are temporally and spatially dynamic and populations may be seen to interact through similar mechanisms as those observed in terrestrial plant communities. In these areas, intense competition for limited niche space, selects for varied defensive and offensive strategies and reproductive life history traits.

A habitat-based simulation framework to design tag-recapture experiments for tunas in the Indian Ocean. Application to the skipjack (Katsuwonus pelamis) population.
Provedor de dados: 20
Autores: Olivier, M.A.Y.
The IOTC initiated a discussion to organize a large scale tagging program concerning the major tropical tuna species and fisheries. According to the terms of reference for the working party on tagging (Anon., 1999), prospective simulations are needed to help designing tag -recapture experiments. The purpose of this paper is to present the methodology developed to help designing the future tagging program. It is based on three stages: tag recovery simulations with an habitat -based advection-diffusion-reaction model; bootstrapping of the recovery data sets; population parameter estimation and comparison of scenarii. Different scenarii are studied to check the reliability of the method and its ability to compare various t agging experimental designs....

Autores: Parsons, E.C.M.; Jenner, K.C.S.; Baldwin, R.; Rudolph, P.; de Boer, M.N.; Eyre, E.L.; Simmonds, M.P.; Keith, S.G.; Rosenbaum, H.C.; Peddemors, V.M.; McCabe, K.A.; Burton, C.L.K.; Jenner, M.N.M.
This paper presents a synthesis of mainly published information relating to the cetaceans of the Indian Ocean Sanctuary (IOS). It highlights a number of new studies and other initiatives linked to the Sanctuary and reviews the current understanding of the biology of the Sanctuary’s cetaceans. Cetaceans in the IOS are exposed to a range of threats, including by-catch and the effects of climate change. Whilst no quantification can be made of these threats at this time, they may still be significant for the conservation of populations. The role of the IOS in stimulating research to further establish the status of cetacean populations is acknowledged.

Sebkha is a North African vernacular name for a shallow, salty depression. It is a common wetland type especially in semi-arid and arid climates but less so in sub-humid climates. In Tunisia, about 80 wetlands of this type stretch from north to south, most of them located within a short distance of the coast although not usually connected to the sea. They play a major hydrological role in stocking flood waters, recharging and/or discharging groundwater and are prime habitats for a diverse and typical fauna and flora thus generating many benefits to local communities and society as a whole.

Habitat heterogeneity effects on macro- and meiofauna (especially  nematodes) in Punta Francés coral reef (SW Cuban Archipelago)
Provedor de dados: 20
Autores: Armenteros, M.; Ruiz-Abierno, A.; Sosa, Y.; Pérez-García, J. A.
Benthic macrofauna and meiofauna distribution patterns were  described in a tropical coral  reef (Punta Francés, Cuban  Archipelago, Caribbean Sea). Density and main taxa composition for macrofauna and meiofauna and species diversity and  organismal traits for free-living nematodes were compared among four habitats: seagrass bed, sand flat, dead coral and hard  bottom. Strong spatial patterns of distribution across habitats were detected and explained by a complex combination of  habitat features. Signal/noise ratio for macrofauna data of distribution was enough strong to detect changes across habitats  but the sizes of sampling devices were not adequate to represent the real patterns in the nature. Meiofauna patterns of  distribution were driven by the...

The biology and distribution of Haplochromis spp in the Nyanza Gulf prior to the total invasion of the Gulf of Nile perch, Lates niloticus (L)
Provedor de dados: 20
Autores: Mwalo, O.M.
The work reported was conducted during the watershed period of 1976 when Nile perch (Lates niloticus) started to replace Haplochromis spp. in dominance in the Nyanza Gulf of Lake Victoria. Seventy four "groups" of Haplochromis species flock obtained from a stock assessment survey of that year were used in the study. The length of fish examined varied between 57 and 237 mm total length, and between 1 and 182 g wet weight, with means of 101.05 mm and 18.53 g respectively. Frequency distribution curves for both sexes were unimodal with a maximum between 70 and 130 mm. The t-test showed that the two sexes came from the same population. Clutch size per fish (mean weight 25.3 g and mean total length 106.7 mm) was 78 eggs. The minimum size at maturity was 89 mm...

Coral reef degradation in the Indian Ocean. Status reports and project presentation 2000
Provedor de dados: 20
The temperatures of the world’s oceans are increasing at an accelerating rate. Recent estimates indicate that the magnitude of these increases might be as much as several degrees over the next century and undoubtedly, the impacts of these changes on the Earth’s ecosystems are likely to become increasingly obvious. Coral reefs have already shown dramatic responses to the increasing ocean temperatures. Under normal temperature conditions, reef-building corals, which form the foundation of coral reefs, are living very near the maximum sea temperatures that they can tolerate. If they are exposed to even modest increases in sea temperatures, perhaps only 1° C - 2° C, they become stressed and often ‘bleach’. This bleaching of corals is a response to stress, and...

Advise on Biologically Allowable Catch (BAC) for Southern Argentine anchovy (Engraulis anchoita, 41° S-48° S) during 2012. To assess the evolution since 1990 and the current status of Argentine anchovy Southern stock, an Age Structured Population Model (ASPM) was used. Modeling of catches according to a four-month period pulses allowed to predict annual yields so as to get them close to the nominal catches officially recorded. Some independent indexes of stock abundance (eight acoustic estimates of total biomass and five estimates of spawning stock biomass obtained with the Daily Egg Production Method) and the proportion of individuals per age group assessed during the same cruises were used to calibrate the fitting. No stock-recruitment function but a...

Ozone treatment of textile wastewater relevant to toxic effect elimination in marine environment
Provedor de dados: 20
Autores: Guendy, H.R.
Ozone is a powerful oxidizing agent. The reaction of ozone with organic compounds in aqueous media has achieved a variety of treatment goals. The advantage of ozonation over the other oxidants is that the degradable products of ozonation are generally non-toxic, its final products are CO2 and H2O, and also the residual O3 in the system changes in few minutes to O2 .Convential treatment of textile wastewater includes various combinations of biological (activated sludge), physical and chemical processes. The dyestuffs existed in these wastewater are highly structured organic molecules which are hardly break down biologically. Decolorization of two types of dyes, Direct Pink 3B and Reactive Violet SH- 2R, by ozonation in aqueous medium was studied in presence...

Whitemouth croaker Micropogonias furnieri fishery  during three intensive fishing seasons in the outer area of the La Plata River (Argentina-Uruguay) is analyzed. Resource exploitation in the South Atlantic area shows a general retraction of the distribution range and an isolation of the La Plata River stock where most of the fishing effort concentrates. The species market evolution brought about, for Argentina and Uruguay, an important shift in its dynamics as of 1992, when the product insertion in Asiatic markets generated an important commercial attraction and a subsequent increase in the fishing effort by the argentine inshore coastal fleet. This caused a change in the fishery development in Argentina and the establishment, in winter, of a fleet...

Analyse de la biodiversité et de la production ichtyques dans trois lacs nord Africains : Merja Zerga (Maroc), Garâat Ichkeul (Tunisie) et lac Edku (Egypte)
Provedor de dados: 20
Autores: Abdelzaher, H.M.A.; Ramdani, M.; Flower, R.; Kraiem, M.M.; Fathi, A.A.
This  survey first presents an inventory of fish species in the three studied sites.  Altogether 17 fish species were found in Merja Zerga (Morocco), 25 species in Garâat Ichkeul and 16 species in Edku lagoon. Three fish groups live in these brackish lakes : sedentary fish, marine fish and freshwater fish. The second part of the study deals with the production of the different species. This production mainly rests upon Mugilidae and Anguilla in Merja Zerga and Ichkeul, while, in Edku, Tilapia is its principal component. In all these sites fish production seems to be decreasing these last years, because of over-fishing and essentially of the deterioration of the environmental factors, especially the  hydrologic ones.

Drilling fluid base oil biodegradation potential of a soil Staphylococcus species
Provedor de dados: 20
Autores: Nweke, C.O.; Okpokwasili, G.C.
Staphylococcus sp. isolated from oil-contaminated soil was grown in 1% drilling fluid base oil, HDF-2000, as a sole source of carbon and energy. The organism has strong affinity for the substrate, growing at the rate of 0.16 h-1. It uses adherence and emulsification as mechanisms for oil uptake. In a nutrient-rich marine broth, base oil (up to 2.0% v/v) and glucose (up to 1.6% w/v) have no significant effect on the growth rates. This showed that the  Staphylococcus sp. is a strong primary utilizer of the base oil and has potential for application in bioremediation processes involving oil-based drilling fluids.

Distant water fishing nations (DWFN) began longlining for tuna in the Western Indian Ocean (WIO) in the early 1950s, initiated by the Japanese soon followed by the Taiwanese (1954) and Koreans (1960). Large scale industrial purse seining began in 1983 when the French and Spanish fleets moved into the Western Indian Ocean from the tropical Atlantic. By 1986 some 6 % of the world tuna catch (143,099t out of 2,400,000t) was coming from the WIO purse seiners; by 1997 this had risen to 14 %. Virtually all the purse seiners active in the WIO are licensed to fish in the Seychelles EEZ; SFA's data therefore reflect the entire WIO purse seine catch (based upon daily catch and effort reports or logbooks which must be provided to SFA by all licensed vessels). At...

Lithostratigraphic Summary For Leg 175: Angola-Benguela Upwelling System
Provedor de dados: 20
Autores: Anderson, L.; Maslin, M.A.; Jansen, F.; Lin, H.; Pufahl, P.K.; Pérez, M.; Brüchert, V.; Vidal, L.
During Ocean Drilling Program Leg 175, 40 holes were drilled at 13 sites, and 8003 m were recovered with the aim of reconstructing the late Neogene history of the Angola-Benguela upwelling system on the southwest African margin. This system is one of the great upwelling regions of the world and is characterized by organic-rich sediments that provide an excellent record of productivity back to the middle Miocene. Understanding the sedimentology and stratigraphy of these sediments will provide important new information on the paleoceanography of this region, including the complex role the ocean plays in global carbon cycling and climate change. This contribution summarizes the sedimentologic and stratigraphic data compiled on board the JOIDES Resolution...

The islands of Zanzibar are located about 40 kilometers from the African continent, in the shallow coastal waters of the Indian Ocean. As the remnant of an economic center of the Omani Empire, which attained its climax in the middle of the 19th century, Zanzibar today boasts a culture and history closely linked with its historic events: Shirazi, Persian and Omani settlers, Indian and Arabian architecture, spicy dishes, slave caves, and historical figures such as Speke, Livingston and Tipu Tipp have all left their marks. Everywhere on the island, mementos of this past can be seen and are recounted in tales of myth and reality passed down from one generation to the next. Furthermore, the abundance of unique marine and terrestrial fauna and flora make...

Two of the most important frontal systems of the Argentine Sea (SW Atlantic Ocean) were compared to obtain evidences on the regulatory mechanisms of food web length, incorporating both spatial (areas within fronts) and temporal (presence or absence of frontal structure) variability. The stable isotopes of Carbon and Nitrogen were used to evaluate the origin and composition of the organic matter used by primary consumers, the structure of food webs, the trophic levels of several taxa and the benthic-pelagic coupling within each system. In the Río de la Plata estuarine front, different sources of organic matter would support the food webs occurring in the three areas of the system. The particulate organic material (POM) would be the main resource supporting...

Autores: Temperoni, B.
Oithona nana (Copepoda: Cyclopoida)is a widely-distributed neritic species, which often comprises up to 90 percentage of the zooplankton in many coastal areas. This small copepod plays an important role as a dominant prey in the diet of Engraulis anchoita larvae, which is a main component of major ecological relevance in the pelagic food webs of the Argentine Sea (SW Atlantic Ocean). The objective of this study was to estimate, for the first time, the seasonal variation of O. nana secondary production in a temperate region: coastal waters off Buenos Aires province, Argentina, at the EPEA Station (Estación Permanente de Estudios Ambientales, (38°28' S-57°41' W).

Autores: Madirolas, A.
Two joint Argentine-British acoustic surveys specifically targeted on the southern blue whiting (Micromesistius australis) were carried out during September 1994 and 1995. The surveys confirmed the existence of a spawning concentration area located south from San Carlos Strait, in waters south of Malvinas Islands, ASW. The obtained point estimates of blue whiting abundance were 84801 t for the 1994 survey and 140953 t for the 1995 survey. The surveys also provided information on the school structure and behavior as well as some clues about the complex migration pattern of the species.

La reproduction et le recrutement de l’une des plus importantes espèces exploitées par les pêcheries démersales mauritaniennes sont étudiés. Pour ce faire, on utilise les données de 24 campagnes de chalutage systématique organisées de mai 1994 à avril 1995 dans la zone du Cap Blanc (20°30N) sur des profondeurs de 10 à 100 mètres.  On montre que l’activité de reproduction du poulpe s’étale sur toute l’année, particulièrement au niveau de la frange côtière. Deux périodes d’activité intense de reproductrice semblent exister chez le poulpe: une première, en mars-mai, puis une seconde, plus importante, en septembre et octobre. L’activité de reproduction de mars-mai est plus étalée dans le temps et moins intense (concerne des effectifs faibles), alors que celle...

Coastal Impacts of Water Abstraction and Impoundment in Africa: the Case of Rufiji River
Provedor de dados: 20
Autores: Shaghude, Y.W.
Construction of large dams with reservoir type storage impound water behind them for seasonal annual, and in some cases for multi-annual storage and regulation of a river. Similarly, tubewells abstract surface and ground water bodies from their natural flow. The impoundment of water by damming and its abstraction through tubewells are common practices in the world and even within the Africa region (WCD, 2000). Globally, the number of large dams has grown at a tremendous pace during the last 50 years (Fig. 1.1) The fast growth in dam construction is driven by an increasing demand of water from urban and rural communities for reliable freshwater supply, agricultural irrigation and hydro-electric power. As these practices become more widespread, they are...

The taxonomic composition, abundance and spatio-temporal distribution of copepods were analysed from monthly zooplankton samples collected in Makupa creek and Mombasa Harbour (Makupa creek was until recently subjected to considerable dumping of domestic and industrial waste). At least 51 copepod species belonging to 38 genera in the families Calanoida (25), Harpacticoida (5), Poecilostomatoida (7) and Cyclopoida (1) were identified. The most common genera were Acartia, Acrocalanus, Corycaeus, Oncaea and Oithona. Copepods bloomed in the wet months of November and April (75 to 158/m3). Abundance was consistently high near the creek mouth and low within the creek enclosure. Copepod diversity (H’) was slightly higher (2.00 to 2.57) during September, November,...

Redistribution and Transformation in the South African Fishing Industry: The Case of the Squid Fishery
Provedor de dados: 20
Autores: Sauer, W.; Britz, P.; Mather, D.
Political normalisation in South Africa during 1994, and the drafting of the Marine Living Resources Act 1998, led to the imperative to transform the fishing sector to more equitably reflect the racial demographics of the country. The squid fishery, like most other South African fisheries, has historically been dominated by white ownership of access rights and vessels. The squid fishery is an effort limited hand-jig fishery with each operator possessing permits for a certain number of individual fishers. Imposition of racial equity in the squid industry was attempted by means of simple redistribution of a proportion of fisher permits, away from existing boat owners to new entrants from historically disadvantaged communities. The lack of human skills and...

Autores: Santana, T.; Camejo, J.
El objetivo de esta reseña fue destacar la importancia que tiene la presencia de las grasas y los aceites vegetales en la dieta para niños. En el trabajo se exponen las características fundamentales de ambos grupos de lípidos. Se compara la grasa láctea y la grasa materna en cuanto a composición, haciendo énfasis en esta última debido a que los alimentos para infantes deben mantener la relación de ácidos grasos esenciales en el mismo orden en que se encuentran en la grasa materna. Se resumen los requerimientos de grasa del niño en distintas etapas de su vida, la composición de los aceites vegetales más utilizados en la elaboración de los alimentos, así como algunos aspectos a tener en cuenta al seleccionar una grasa para utilizar en la alimentación infantil.

The Fringing Reef Coasts of Eastern Africa-Present Processes in Their Long-term Context
Provedor de dados: 20
Autores: Arthurton, R.
Sea-level changes through the Quaternary era have provided recurrent opportunities for the biosphere to significantly shape the coastal geomorphology of eastern Africa. Key agents in this shaping have been the calcium carbonate-fixing biota that have constructed the oceanfacing fringing reefs and produced the extensive backreef sediments that form the limestone platforms, cliffs and terraces that characterise these coasts. Today’s reefs comprise tough, algalclad intertidal bars composed largely of coral rubble derived from their ocean front. They provide protection from wave attack to the inshore platforms with their sediment veneers and their beach and beach plain sands that are susceptible to erosion. If the eastern African coasts are subjected to the...

Desarrollo de una metodología sencilla para la georreferenciación y medición de distancias a partir de imágenes de satélite sistemáticamente georreferenciadas
Provedor de dados: 20
Autores: Gónima, Leonardo; Ruíz, Libardo E.; González, Marcos E.
Uno de los principales problemas para una precisa georreferenciación y medición de distancias a partir de imágenes de satélite, especialmente en zonas geográficas con una gran dinámica morfológica y ambiental, reside no solamente en la dificultad para la identificación de puntos de control (GCPs, por su sigla en inglés), sino también en las limitaciones reales para el acceso a dichos lugares. En el presente trabajo se propone una metodología relativamente simple para la georreferenciación y la medición de distancias a partir de imágenes de satélite, basada en la utilización de imágenes de la reflectancia de la superficie previamente calculadas y luego orientadas hacia el norte (georreferenciación sistemática). A partir de estas imágenes y fijando un punto...

Autores: Li, Zhilong; Chen,  Zishen.
Research on the laws controlling the shoreline equilibrium shape has been one important topic of studying the evolvement and stabilization of sandy coasts. After a brief review of the progress on the equilibrium shape laws research, five models are introduced in detail. Advantages and disadvantages of these models are then discussed, which leads to the conclusion that the empirical formula integrating with analysis of mechanism should be the future direction of study on the headland-bay equilibrium shape laws. Finally, the importance of the study on the equilibrium shape of headland-bay in China is also discussed.

Seychelles tuna bulletin : second quarter 1989
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean during the second quarter of 1989, remained at 47 in April and May, dropping to 46 in June.  This represents a significant increase in the number of vessels compared to same period last year, when an average of 38 vessels were in operation. Fishing results obtained during the second quarter were mediocre compared to the exceptionally high catches made at the beginning of the year.  Record catch rates averaging 26 mt/day during the first quarter dropped from 20 mt/day in April to a mere 9 mt/day in May.  These results are however not unusual for this time of the year.  Daily catch rates for the second quarter averaged 16 mt/day, reaching the same level as in 1987, whereas 18 mt/day was reported...

Information about the austral cod Salilota australis caught in the Patagonian shelf including the area around Malvinas Islands (SW Atlantic)as well as some data from annual research surveys carried out as of 1992 to 1998 were analyzed. On this basis, the fishery was studied and the abundance of the stock inhabiting the area under Argentine control was estimated. To calculate the optimum yield as a function of both age-at-first catch and fishing mortality, the Yield-per-Recruit model was used. Some biological reference points were also identified and an exploitation strategy based on low risk of collapse recommended. Austral cod landings, although small, showed an increasing trend as of 1990 that reached a maximum of 14,900 tons in 1998. Most of the catches...

Some Properties of Glutamate Dehydrogenase from the Marine Red Alga Gracilaria sordida (Harv.) W. Nelson
Provedor de dados: 20
Autores: Mtolera, M.S.P.
Glutamate dehydrogenases (GDH, EC 1.4.1.2-4) catalyse the entry of ammonium into the organic cycle via amination of a-ketoglutarate and its release via deamination of Lglutamate. NAD-GDH facilitates NAD-/NADP-dependent deamination while NADPH-GDH facilitates NADH-/NADPH-dependent amination reactions. In the study reported here, GDHs were extracted from the red alga Gracilaria sordida and purified 10- to 180-fold before examining their amination and deamination reaction properties. NAD-/NADP- and NADH-/ NADPH-dependent activities were the order of 11:1 and 1:1.8, respectively. The pH optima for amination and deamination were 8.2 and 8.4 under NADH- and NADPH- and 8.4 and 9 under NAD- and NADP- dependent activities, respectively. Whereas both NAD- and...

To assess the effect of protein levels in diet on growth of pink shrimp juveniles (Farfantepenaeus notialis), two completely randomly experimental designs were carried out, one at laboratory scale during 8 weeks and the second one in fertilized earthen ponds during 20 weeks. Samples of pink shrimps obtained after spawning in the laboratory, were used. Isocaloric practical diets containing 35, 40 and 45% were used in the first experiment and 40 and 45% protein in the second one. In both trials, shrimps fed with 45% protein diet reached the highest growths. The nutritional factors assessed were always better in that organisms fed with the diet of higher protein content. The histological analysis of the hepatopancreas in shrimp feds with diets containing...

Working Group on capital needs and availability in artisanal fisheries: methodology and lessons learned from case studies
Provedor de dados: 20
Autores: Kébé, M.; Horemans, B.; Odoi-Akersie, W.
The existing way of financing of artisanal fisheries in West Africa is an element which has received so far few attention during the preparation of development policies. Unfortunately, this lack of knowledge has led to field actions of which the results have often be disappointing. Moreover, the informal sector continues to be the main source of financing of artisanal fisheries and the repayment rate of loans granted by the institutional sector is generally low. On this basis; the Programme for Integrated Development of Artisanal Fisheries in West Africa (IDAF) set up a Working Group on capital needs and availability in artisanal fisheries. Its objectives are: (i) to elaborate a simple but efficient methodology likely to facilitate the identification of...

Autores: Campredon, P.
Au cours d’une mission du N/O N’Diago en juin 1987, des observations ont été réalisées sur le peuplement ornithologique présent à cette époque au large des côtes mauritaniennes. 17 espèces marines ont été recensées qui sont pour la plupart des sub-adultes non nicheurs de l’air Paléarctique (par exemple &lt;Chlidonias niger&gt;, &lt;Sterna hirundo&gt;, &lt;Calonectrice diomedea&gt;) soit des nicheurs de l’hémisphère austral en hivernage (par ex. &lt;Oceanites oceanicus&gt;). Une estimation semi-quantitative des effectifs montre que ces 4 espèces composent l’essentiel du peuplement. Les navires de pêche jouent à leur égard un rôle important sur le plan alimentaire par les déchets des poissons rejetés à la mer mais aussi pour la satisfaction des autres...

The industrial tuna fishing activity in the western Indian Ocean: Impact on the economy of Seychelles, report for the year 2004
Provedor de dados: 20
Autores: Marguerite, M.A.; Baker, C.
Fishing has traditionally played an important role in the socio-economic development of the country, providing an important source of exports and foreign exchange earnings, job creation, government revenue and most of all an important source of animal protein for the population. With the emergence of Port Victoria as a major tuna landing and transshipment center in the region coupled with the country's venture in tuna canning activity, the importance of the fisheries sector has grown even further to establish itself as a major economic activity, an important source of foreign exchange earnings and contributor to the country's wealth generation. The Industrial Tuna Fishing Activity in Seychelles has since its outset been an important source of foreign...

Autores: Estela, F.A.; López-Victoria, M.
Knowledge of the geographical distribution of the birds in the Colombian Caribbean is still meager. Coastal wetlands are among the less studied environments in the area and one of the most important for their high bird richness. Since 1998, inventories and monitoring of the bird populations of the lower part of the Sinú river have been made. Until July 2005, 296 bird species have been recorded for the area, 41 of which are new for this part of the Caribbean; in addition, new wintering localities were noted for eight migratory species. Breeding records were obtained for 98 species. Three species are threatened at some level and six have a restricted geographic distribution. New records for the area are explained in terms of the limited previous knowledge of...

Data used to generate the Tables and Figures presented in this report are based on logbook returns from the fishing vessels. Readers should, therefore, be aware that figures presented in this report are likely to change in future publications of the Tuna Bulletin once all the data relating to the quarter being reported on becomes available. The initial estimate for the total WIO purse seine tuna catch for the first nine months of 1994 is 176,216 Mt. However, this figure may also be^ revised upwards when trips starting in the third quarter of 1994 and finishing in the fourth quarter are included in the next quarterly Tuna Bulletin of 1994. This compares with 203,797 Mt caught in the first nine months of 1993. Some 2,532 days were fished in the third quarter...

Two pelagic cruises were carried out by R/V"Cap.Oca Balda" in the spring of 1988 and the following summer. Anchovy samples were taken in order to increase the knowledge on the differences between two main stocks of the species, inhabiting the Argentine Sea from 35°S southwards, with distributional boundary situated at about 41°S. Length-weight relationships were statistically different among populations. Weight-at-length values calculated for the summer cruise were higher tha sprin estimates, and they were also higher within Northern individuals. The differences were not statistically significant between stocks, but there are reasons to believe that if ages 1 and 6 of both stocks had been represented those differences would have been increased.

Autores: Lett, Christophe; Veitch, Jennifer; Van der Lingen, Carl D.; Hutchings, Larry.
The Lüderitz upwelling cell and Orange River cone (LUCORC) area, a transboundary region between South Africa and Namibia, is considered to be an environmental barrier to transport of ichthyoplankton from the southern to the northern Benguela upwelling ecosystems. We use environmental data and modelling to assess the potential mechanisms responsible for this barrier: environmental data were extracted from the 1 × 1° World Ocean Atlas 2001 database and used to build maps of annual mean salinity, temperature, chlorophyll, dissolved oxygen and nutrient concentrations; outputs of a regional circulation model were used in an individual-based model to assess the transport of passive particles from the southern to the northern Benguela. The data show no clear...

Survey of the Demersal Fish Resources of the outer shelf and slope off Ghana
Provedor de dados: 20
This survey focused on the outer shelf and deep water slope off Ghana and the catch-distribution analyses were therefore performed for four depth strata, outer shelf (&lt; 100 m), upper slope (100-300 m) mid slope (300-600 m) and lower slope (&gt;600 m). In the analyses the “Demersal” group includes commercially important families as Sciaenidae, Haemulidae (=Pomadasyidae), Serranidae, Sparidae and Lutjanidae, and especially in deeper waters the Merluccidae, Macrouridae and Moridae. The Pelagic group includes Engraulidae, Clupeidae, Carangidae, Scombridae, Sphyraenidae, Gempylidae and Trichiuridae (the latter family is actually mainly benthopelagic). For the analysis the “other” group includes all species not accounted for in the groups listed.

This dissertation analyses the barotropic and baroclinic response of the Argentinean Continental Shelf to different forcing using a three-dimensional numerical ocean model. The study aims towards a systematical exploration of the physical processes that control the circulation. To facilitate the dynamical understanding of the results our experimental strategy was to start with a three dimensional barotropic model (constant density) that examines the influence of winds and tides, and to progress to a more complex case including density stratification (baroclinic model). It was found that the average annual circulation, forced only by the wind, shows a strong contrast between the northern and southern region of the study area. A detailed analysis...

Autores: Rincón-Díaz, M.P.; Rodríguez-Zárate, C.J.
The San Bernardo Archipelago, in the Colombian Caribbean zone, is well recognized for being a sporadic nesting and feeding area for the green, hawksbill and loggerhead turtles. Due to the fact that the San Bernardo Archipelago has outstanding coral areas, marine grasses and sandy beaches and their environmental offers for the marine turtles have not been described yet, it was opportune to carry out this study between July and October of 2002. Thus, this research tends to fill this gap by describing the nesting beaches and feeding areas according to their geomorphologic and biotic aspects and, for the later areas, some oceanographic aspects too. Seven potential nesting beaches and 20 stations on feeding areas were evaluated to identify natural and...

In the Azores Islands (NE Atlantic), between 1986 and 1998, Dalatias licha was caught to obtain liver oil. A drastic abundance decline, probably attributed to a high level of exploitation, was observed. In Argentina elasmobranchs have undergone intensive fishing and, at present, catches are compromised. The history of the fishery in Azores should be taken as example and warning when implementing elasmobranchs fisheries management in Argentina.

The pacific oyster Crassostrea gigas, one of the most successful invasive species worldwide, inhabits intertidal and shallow subtidal marine and mixohaline coastal waters. In Argentina the species colonized natural ecosystems of southern Buenos Aires and northern Patagonia. However, in the last years the presence of oysters in the coast of Punta Rasa, northern Buenos Aires, was reported. Therefore, with the aim of recognizing the identity of the species, an exploratory survey in the salt marshes close to San Clemente stream was carried out. Individuals were identified as C. gigas (shell height up to 37 mm, density up to ~390 ind. m-2). Oysters were found clumped in small reefs in muddy substrates mixed with shell debris, attached to the stems of Spartina...

Shifting baselines and the extinction of the Caribbean monk seal
Provedor de dados: 20
Autores: Baisre, J. A.
The recent extinction of the Caribbean monk seal Monachus tropicalis has been considered an example of a human-caused extinction in the marine environment, and this species was considered a driver of the changes that have occurred in the structure of Caribbean coral reef ecosystems since colonial times. I searched archaeological records, historical data, and geographic names (used as a proxy of the presence of seals) and evaluated the use and quality of these data to conclude that since prehistoric times the Caribbean monk seal was always rare and vulnerable to human predation. This finding supports the hypothesis that in AD 1500, the Caribbean monk seal persisted as a small fragmented population in which individuals were confined to small keys, banks, or...

Management of Oil Spill Dispersal Along the Nigerian Coastal Areas
Provedor de dados: 20
Autores: Nwilo, P.C.; Badejo, O.T.
Nigeria, one of the world’s largest oil exporters, has a coastline of approximately 853km facing the Atlantic Ocean. This coastline lies between latitude 4o 10’ to 6o 20’ N and longitude 2o 45’ to 8o 35’ E. The Nigerian coast is composed of four distinct geomorphology units namely the Barrier-Lagoon Complex; the Mud Coast; the Arcuate Niger Delta and the Strand Coast. 90-95% of export revenues in Nigeria is from the oil sector. Nigeria’s oil reserves are about 31.5 billion barrels, while Nigeria’s crude oil production averaged 2.118 million barrels per day in 2002. Oil spillage is a major environmental problem in Nigeria. Between 1976 and 1996 Nigeria recorded a total of 4835 oil spill incidents, which resulted in a loss of 1,896,960 barrels of oil to the...

Aspectos generales de la pesca del bonito (Sarda sarda)en la Argentina
Provedor de dados: 20
Autores: Hansen, J.E.
Basic aspects of the fising of Bonito in Argentina such as: catch statistics, fleet and gears, season and fishing grounds, and catch per unit effort (CPUE)are analized. FAO World Catch Statistics show that none of the different populations of Sarda sarda or other species of the Genus may support a highly productive fishery Exceptions are Sarda chilensis and S.sarda from the Black Sea, which us exploited by Turkey. On the basis of available information it may be inferred that the Bonito of Argentina has more competitors and a narrower thophic spectrum than that from the Black Sea.

Usando series de tiempo de promedios diarios de nivel del mar en años caracterizados por la ocurrencia de eventos El Niño en la estación mareográfica de La Libertad (02°15'S-81°27'W), se aplicaron las técnicas del análisis espectral para determinar la correlación existente entre los eventos pasados y el primer semestre de 1997. Se obtuvieron niveles significativos de coherencia entre el evento El Niño 1982-1983 con el evento del 1997. El análisis espectral comparativo permitió obtener las ondas predominantes, la amplitud y el ángulo de fase de cada una de ellas. Con estos parámetros y aplicando la serie de Fourier, se generó una serie del nivel del mar que permitió predecir el comportamiento del nivel del mar en La Libertas desde julio 97 hasta marzo 98...

Résumé:  Cette étude traite de la biologie et de la dynamique des populations d’anchois (Engraulis encrasicolus) des côtes mauritaniennes. Après un bref rappel des conditions climatiques et hydrobiologiques de la région, une tentative de mise en évidence de race ou population locale a montré que cette espèce pourrait être rattachée à la population méridionale atlantique du Golfe de Gascogne. En  Mauritanie, l’Anchois n’est pêché que de façon accessoire. Les captures les plus abondantes sont réalisées de mai à Septembre essentiellement dans la zone nord où l’on observe un upwelling permanent. Pour évaluer la taille du stock, des estimations de biomasse par échointégration ont été effectuées, mais celles-ci n’ont pas permis de donner un ordre de grandeur...

Status of Breeding Seabirds in the Red Sea and Gulf of Aden
Provedor de dados: 20
The Red Sea and the Gulf of Aden represent a complex and unique tropical marine ecosystem. The Red Sea was formed by the northerly extension of the African rift valley system and is about 2,000 km long. The Gulf of Aden is a branch of the Indian Ocean and has a length of 1,400 km. The region has a remarkably high biological diversity and a high degree of endemism, particularly for fish and corals. Information available on seabirds for the region is limited, with the majority of studies carried out one to two decades ago. Accounts indicate that there are 17 true seabird species and 14 other water bird species. Among these birds the Jouanin’s petrel and swift tern have the smallest sub-populations. The white-eyed gull, endemic to the Red Sea and Gulf of...

Autores: Jeske, R.
Mientras predominan las aguas salobres en la Ciénaga Grande se destacan las formas bacterianas halófilas. Durante la época de lluvias (invierno, disminuye la salinidad, sin embargo las formas halófilas aumentan en número. La reproducción de bacterias de agua dulce se inicia sólo cuando la salinidad llega bajo un valor de un 10°/o/o. Estas alcanzan su valor máximo temporáneo en salinidades de un 3°/o/o. Al mismo tiempo disminuyen las formas halófilas. Observaciones sobre contaminación fecal se realizaron en las aguas de la Ciénaga. Como indicador se utilizó Escherichia coli. En las inmediaciones de los pueblos de pescadores es posible detectar cierta contaminación. En cambio, en el resto de la Ciénaga, en contados casos se observa E. coli. La presencia de...

Impacts Of Bleaching On Coral Communities On Artificial Reef Structures In Maldives
Provedor de dados: 20
Autores: Clark, S.
A research programme to evaluate the feasibility of using artificial reef structures (ARS) to rehabilitate degraded reefs was conducted in Maldives between 1990-1994. Detailed monitoring and analysis of coral recruitment patterns on the ARS over a period of 3.5 years demonstrated that a diverse community of branching corals developed within three years with a similar composition to adjacent reef flats. A warm water anomaly of +3° C occurred in Maldives between late April and May1998 resulting in extensive bleaching of corals and other zooxanthellate reef invertebrates. On the ARS bleaching was followed by full to partial mortality of certain corals within 4 - 6 weeks of the onset of bleaching. Branching species of the genera Acropora and Pocillopora were...

Entre los años 1979 y 1984 la producción de camarón en el Ecuador tuvo un aumento dramático y 1983, fue el año de más alta producción registrada, la producción totalizó 36,6 miles de toneladas métricas, con una exportación valorada en 183 millones  de dólares, es decir, cerca de tres veces la cantidad producida en 1979. Este incremento espectacular fué debido principalmente a la expansión de la industria  de la cría de camarones de piscinas, haciendo que el Ecuador se convierta en el líder de los países productores de criaderos de camarones. El desarrollo vertiginoso de la industria de la cría del camarón y a los problemas que se enfrenta dicha industria no han sido bien documentados.

Se determinaron algunas características físicas y biológicas de la columna de agua en Bahía Chile, Isla Greenwich, por medio de la distribución espacial de temperatura, salinidad y clorofila "a", durante el verano austral (febrero de 1990). Las distribuciones verticales de las isotermas, isohalinas, isopicnas e isolíneas de clorfila "a" muestran que la circulación predominante es termohalina, influenciada por la topografía de la bahía, con un flujo subsuperficial que entra por el lado noroccidental de la misma y se dirige hacia el centro (siguiendo la topografía), aflora en el extremo interior y sale superficialmente por el lado oriental.

Minerals and Energy Sources
Provedor de dados: 20
Salt can be considered as the most widespread mineral in Eastern Africa and its recovery from the sea is a comparatively simple process given certain environmental conditions. The location of solar saltworks is controlled by the rainfall regime and the occurrence of suitable impermeable soils. These conditions occur from Ngomeni northwards to the Lamu area. Extensive saltworks have been established at the Gongoni-Fundi Is area and Kurawa. The total area dedicated to salt production is over 5,000 hectares that yield an average of over 170,000 tonnes of salt annually. The method of salt production utilised by the five established companies is very much the same throughout the area. Seawater is introduced into the ponds which are run in series. Slight...

Autores: Hallier, J.P.; Michaud, P.
Since 1983, tuna purse seine fishery has increased rapidly in the Indian Ocean. This fishery, being mostly based in Seychelles, represents an excellent opportunity to this country. However, it is essential that a good management strategy be adopted in order to ensure the rational exploitation of the resources. Since this fishery is in its early stage of development, it is not yet possible to obtain an accurate assessment of the stocks based on usual stock assessment methods. Nevertheless, from existing knowledge on the Indian and Atlantic oceans, a preliminary analysis of the resources is attempted. Of the two stocks studied, the skipjack, known as an opportunist species, can support a higher exploitation rate than the yellowfin. It would seem that catches...

Among other results, it was found that when hake is handied property it maintains good quality levels up to 10 days after catch, irrespective of season. Its total storage life in boxes with ice is approximately two weeks. Although total storage life remained unchanged, it was found that quality levels tended to be significantly higher if overfilling of boxes was avoided, if the fish was gutted immediately after catch, or if hake was stored in containers with seawater.

The Global Oceanographic Data Archaeology and Rescue Project (GODAR): Sea Level Data Proposal
Provedor de dados: 20
Autores: Woodworth, Philip; Rickards, Lesley.
At its meeting in May 1999, the IOC Group of Experts on the Global Sea Level Observing System (GE-GLOSS) discussed the need for data archaeology of historic sea level records in order to possibly extend existing time series and/or gain access to observations which are not in digital form. Following on from this, a member of the GE-GLOSS attended the GODAR Review Conference in Silver Spring, Maryland in July 1999, and suggested that sea-level data also be included in the GODAR project. The GODAR sea level proposal is this. In many countries there are considerable amounts of historical sea level data in paper form such as charts or tabulations.  These need to be computerised (a) as a backup for data security, and (b) so that they can be subject to modern...

International Instruments for Managing Fisheries in the Indian Ocean
Provedor de dados: 20
Autores: Willmann, R.
The paper sets out with a brief review of the status of marine fishery resources and the principal fisheries management issues in the Indian Ocean region. It then presents important international instruments for fisheries management and, in general terms, reviews progress in their implementation. The term ‘international’ is defined broadly to also encompass the conventions of regional or sub-regional fisheries management organizations (RFMOs). The paper focuses on fisheries management in the conventional sense of making optimum use of the fishery resources. Instruments addressing the protection of fish habitats from pollution and degradation are also addressed but in less detail.

Effect of shrimp head meal inclusion level in litopenaeus schmitti juveniles diet.
Provedor de dados: 20
Autores: Jaime Ceballos, B. J.; Fraga Castro, I.; Galindo López, J.; Alvarez Capote, J.S.
This study determined the effect of different shrimp head meal (SHM) levels (0, 5, 15, 25 and 30%) in practical diets for Caribbean white shrimp juveniles Litopenaeus schmitti (0.29 ± 0.0025 g). A totally randomized experimental design was carried out under laboratory conditions during 54 days. There were no significant differences (p &gt; 0.05) in survival of shrimps in all treatments evaluated. This result indicated that SHM included at 5, 15 and 25% in diet promoted growth. The relation of SHM inclusion level in diet with final weight (FW), food conversion rate (FCR) and protein efficiency ratio (PER) were described by the following quadratic equation: FW = 0.8023 + 0.0604 S - 0.0018 S2, 2 =0.81; FCR = 8.0019 - 0.6081 S + 0.0164 S2, R2 =0.82 and PER =...

Dinámica del ultrafitoplancton en el Mar Argentino
Provedor de dados: 20
Autores: Silva, R.I.
Ultraphytoplankton is composed by a group of organisms phylogenetically diverse, which contribute significantly to the total biomass and primary production in different oceanic and coastal pelagic systems. The success of ultraphytoplankton is attributed to its high efficiency in capturing light and nutrients, due to their small cell size and low sinking rate. The community structure is driven by the interaction among biotic and abiotic variables, such as temperature, nutrients, light and predators. The objective of this work was to assess the ecological importance of ultraphytoplankton organisms at the EPEA station, situated in the Buenos Aires coastal pelagic system (Argentina, SW Atlantic), during the period 2000-2009. In particular, ultraphytoplankton...

Mkuranga district is one of the six districts that form the Pwani Region (Figure 1). It was established in 1995, when the eastern part and coastal area of the Kisarawe district was cut off to form the district of Mkuranga. It is a relatively small district, covering 2,432 square kilometers, which is about a quarter of the size of Bagamoyo and about the size of the Zanzibar Islands. The district has about 90 kilometers of coastline, extending from the Temeke to the Rufiji districts. Like much of coastal Tanzania, the district is endowed with coral reefs, mangrove forests, and coastal fisheries. Remote unpopulated islands host endangered species such as the red colobus monkey and attractive birds. In Mkuranga, there are seven coastal villages: Shungubweni,...

Reproductive cycle of edible echinoderms from the Southwestern Indian Ocean:  I. Tripneustes gratilla L. (Echinoidea, Echinodermatata)
Provedor de dados: 20
Autores: Vaïtilingon, D.; Rasolofonirina, R.; Jangoux, M.
The reproductive cycle of the edible echinoid Tripneustes gratilla (Linneaus 1758) was investigated in a population located in the southwest coast of Madagascar (Toliara). The reproductive cycle was followed for two consecutive years (October 1999 to October 2001) and characterised by means of gonad and maturity indices. T. gratilla has an annual reproductive cycle mediated by seawater temperature, day length and feeding activity. The histology of the gonads revealed six different maturity stages grouped in three main reproductive phases: growing and maturing, spawning, and spent and recovering. Reproduction is seasonal. Growing and maturing stages occurred from late summer to early winter correlating with decreasing temperatures and day length. Spawning...

The remote sensing data which are used by marine fishery forecast only can get the information of ocean surface, while Argo data can provide fishery forecast with temperature and saltinity data of deeper area. To use Argo data in cycle, we need to compute its circle to improve the quality of forecast. In 2001- 2008 , the longer circle was 62.7 days and 117.5 days , and the shorter circle was 4.9 days and 9.8 days, which were obtained by power spectrum estimation. And there was an unobvious circle of 7 days. There existed big changes in observed profile data amount between years and within a year.

Analyse de la variation de la température de surface de la mer (SST) aux stations côtières de Côte d'Ivoire.
Provedor de dados: 20
Autores: Mahan, N. Claude; Bamba, S. Barthélémy; Aman, Angora.
Depuis 1977, le Centre de Recherches Océanologiques (CRO) a entrepris des mesures quotidiennes de température de la mer le long des côtes ivoiriennes. Les remontées d'eaux froides qui affectent la côte ivoirienne présentent une forte variabilité à différentes échelles de temps et d'espace. Ces processus environnementaux complexes, irréguliers et difficiles à appréhender ont une grande influence sur un écosystème pélagique instable et par nature changeant (Arfi et al., 1995). Ces mesures répondent à un double objectif concernant l'étude saisonnière de l'upwelling côtier ivoiro-ghanéen pour prévoir les périodes et les zones favorables à la pêche sur le plateau continental ivoirien et à l'alimentation du projet GOOS (Global Ocean Observing System) de la...

In aquaculture are used various drugs and chemicals for veterinary use to prevent or treat diseases, control pests, help production processes and promote growth. These substences are usually incorporated in the so-called feed. Hence, the unregulated use of ingredientes in different formulations as preservatives and dyes may also cause a risk in food safety. The National Fisheries Institute monitor the waste coming from drugs, to comply with international market requirements in relation to quality standards. Residues of Malachite Green (MV) and Malachite Leucoverde (LMV) were in 82 samples of fish meal, shrimp and squid, balanced, nutritional substances in different forms granules, pastes and powders, vitamins, desinfectants, fungicides and medicated...

The fisheries policy of the Republic of Seychelles
Provedor de dados: 20
Autores: Anon.
The fisheries policy of the Government of Seychelles was first drafted in 1986. At that time, both the industrial and artisanal fisheries in Seychelles were in a developmental stage and the policy reflected the needs to promote both the development and conservation of our marine resources as well as maximizing benefits. In 1985 the number of licenses issued for the industrial tuna fishery was 49 for the purse seiners and 165 for longliners with an annual purse seine catch of 130,000 tonnes. The total catch for the industrial purse seine fishery has continued to rise and peaked at around 407, 000 tonnes in the year 2003. The artisanal fishing fleet has declined from 410 vessels in 1985 to 330 in the year 2003, however, the nature of the fleet has changed...

Seychelles tuna bulletin : third quarter 1991
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean increased slightly from 42 at the end of the last quarter to 45 in September. Fishing results improved slightly in the third quarter, with the average catch rates increasing from 15.8 MT/day in the second quarter to an average of 19.0 MT/day in the third quarter.  This represents a slight drop from the same period last year when catch rates averaged 22.0 MT per day; however, it is an improvement over the catch rate of 16.0 MT/day for the same period in 1989. The fishing pattern for the third quarter showed that fishing effort was concentrated between 5 degrees north and 5 degrees south of the Equator in the vicinity of the Northern sector of the Seychelles EEZ.  This follows the same pattern as...

Interaction of Marine Turtles with Fisheries in the Mediterranean
Provedor de dados: 20
Autores: Gerosa, G.; Casale, P.
At present, the impact of accidental catch on sea turtle populations is one of the most urgent problems that must be solved to ensure the survival of all these species worldwide. In the Mediterranean, too, all marine turtle species are affected by fishing activities, in particular the loggerhead (Caretta caretta) and the green (Chelonia mydas) turtles, which are more common than the others and are the only ones breeding in this sea. Since the Mediterranean populations of both species seem to be genetically isolated from the Atlantic ones (Bowen et al., 1992; Bowen et al., 1993; Laurent et al., 1993), fishing-induced mortality probably cannot be counterbalanced by immigration. This implies that the survival of the Mediterranean populations of these species...

Résumé : En 1990, la pêcherie pélagique en Mauritanie s’est caractérisée par d’importantes variations – tant en termes d’effort et de rendement qu’au niveau de la composition spécifique des captures – par rapport aux années antérieures. En effet, l’effort, exprimé en jours de pêche standards, a atteint 9761 jours de pêche standards ; ce qui constitue une augmentation de plus de 21% par rapport à 1989. Aussi, avec 372000 tonnes, les captures totales ont enregistré une augmentation de 4,4%. Pour sa part, la Prise par Unité d’Effort (PUE) a enregistré un recul sensible passant de 44 tonnes/jour de pêche (t/jp) en 1989 à 38 t/jp en 1990. La composition spécifique des captures a été marquée par une augmentation importante de la contribution des sardinelles qui...

Taiwan reorganized the catch statistics compiling group in 1996, with changes proposed in its data processing system. Through joint work between ICCAT experts and Taiwanese scientists, the system was carefully reviewed and verified. During the review, the need for revising the historical catch statistics was noted. The revision of Atlantic data was proposed and accepted by ICCAT in 1997. This paper gives the revision on Indian Ocean longline statistics with brief description on the new system. Major changes in total catches were due to the re-estimation of landings of bigeye and yellowfin tunas for six years based on Japanese import information, recovery of sales records of swordfish and application of conversion factors to processed weight reported...

Autores: Ramírez Stout, O.; Candela Pérez, J.
The subinertial response of sea level to meteorological forcing in the Gulf of Mexico is examined using observations of sea level, atmospheric pressure and surface wind covering the period 1985-1986. Spectral analysis and multiple regression in the frequency domain methods are employed for data processing. The analysis shows that the atmospheric pressure is the principal forcing agent. The response of sea level to atmospheric pressure is found to be non isostatic and dependent on frequency and geographical location; the response is overisostatic in the north zone and underisostatic in the south zone of the Gulf, approaching isostasy only at stations located in the Cuban coast.

Autores: Sánchez, R.P.; de Ciechomski, J.D.; Acha, E.M.
An analysis is presented of reproduction aspects of Argentine Sea blue whiting. The species spawns in the study area mostly during August and September, although some spawners have been detected even in November. Total length at 50-per-cent maturity was 35,4 cm for the males and 38.0 for the females. Significant differences between the length of maturity for individuals of the continental shelf compared to those of the slope, have been obtained. The southern blue whiting is a discontinuous spawner, showing one annual reproduction peak. Fecundity was investigated on the basis of samples collected in 1978 by the RV"Walther Herwig" and "Shinkai Maru". A significant positive correlation was also observed at relating oocyte dry weight and gonad factor, whereas...

Autores: Borrero H., J.I.
El Titiribí (Pyrocephalus rubinus) es un ave abundante y conspicua en América. Pese a ello es poco conocida en sus aspectos de comportamiento. Se ha estudiado detenidamente, especialmente desde el punto de vista de su comportamiento reproductivo, encontrando que, la especie se reproduce durante todo el año, empleando frecuentemente cada pareja el mismo nido para hacer varias posturas. Se sacan algunas conclusiones sobre mortalidad en los distintos estados de desarrollo, desde la postura hasta la salida de los pollos del nido. Se describe igualmente el comportamiento de los padres, respecto a la fabricación del nido y al cuidado de los pollos. Se hace una análisis de los distintos tipos de canto y vuelo, y su significado.

Distribución, abundancia y estacionalidad de Liriope tetraphylla (Hidromedusa, Trachymedusae) en el Océano Atlántico Sudoccidental y su rol ecológico en el estuario del Río de la Plata
Provedor de dados: 20
Autores: Gaitán, E.N.
In zones of high productivity and/or in shallow waters (frontal or upwellings areas, bays and estuaries) the hydromedusae can reach exceptional abundances, denominated 'blooms'. Occasionally, these exceptional abundances are originated from some few individuals that constitute a 'seed population', which is retained in particular places while the environmental conditions are adverse. Liriope tetraphylla is a holoplanktonic and oceanic hydromedusae that often is found forming dense aggregations, which are developed mainly in the Buenos Aires coast during the summer in Argentinian waters (SW Atlantic). The temporal-space distribution and the abundance of L. Tetraphylla in the Subantarctic region were analyzed, with 1458 samples embracing the Argentinian and...

Autores: Schleyer, M.
Increasing numbers of crown-of-thorns starfish (COTs) Acanthaster planci are being found in the Indo-Pacific region (Engelhard 1996, Lassig and Engelhard 1994, Stump 1996). However, there appears to be a gap in the information presented by Lassig and Engelhard (1996) for the Western Indian Ocean (WIO). The Oceanographic Research Institute (ORI) in Durban has been involved in coral reef research in a number of areas in the WIO during this decade and has encountered COTs outbreaks since September 1994. The following brief account summarizes these observations.

Autores: Christiansen, H.E.
This paper describes a method to discriminate different stocks of the Argentine hake (Merluccius hubbsi)based on the counting of white skeletal fibres of the trunk. A total of 713 females were examined from samples coming from a wide area of the Argentine shelf (between 34°30' and 54°00'S)which corresponds to the following systems: Uruguayan, Buenos Aires, northern, central and southern-patagonian. All results may be considered as preliminary due to the incipient nature of the information available on fibre regulation in fish.

Autores: Ben Lamine, Y.; Daly Yahia Kefi, O.; Daly Yahia, N.
The Tunis bay is located in the North Estern coast of Tunisia and receives in its Western part flows from Meliane River. Our study aims to describe the composition and the spatiotemporal distribution of planktonic copepods in the bay in order to identify the effect of the Meliane River supplies on the community. A grid of 19 stations was investigated monthly from July 2004 to December 2004 using a 160 μm mesh size plankton net, towed obliquely from the bottom to the surface. The planktonic copepod community was represented by 21 taxa of Calanoida, 4 taxa of Cyclopoida, 3 taxa of Poicilostomatoida and one species of Harpacticoida. The presence of freshwater taxa like Arctodiaptomus salinus, Microcyclops sp and Thermocyclops sp in the coastal stations...

The boutargue is the salty and dried ovary of the mullet (Mugil cephalus) from Nouakchott (Mauritania) and Tunis (Tunisia). In order to know the nutritional quality of the boutargue, we have used an analytic analysis and dosages of lipids and their fat acids. For this study, we used two different methods of extraction of the lipids: method of Folch modified by Bligh and Dyer and the method of Soxhlet. These experiences show that the boutargue of mullet is rich in lipids, 30.9% in Nouakchott (Atlantic Ocean) and 27,4% in Tunis (Mediterranean Sea). The boutargue is with good nutritional quality. Indeed, each gram of boutargue contains 28,1 mg of fatty acids in Nouakchott and 19,7 mg in Tunisia. Theses fatty acids are subdivide in 3 essential groups: - Fatty...

Hábitos alimentarios y comportamiento trófico del caballito de mar (Hippocampus sp) en la bahía de San Antonio (Río Negro)
Provedor de dados: 20
Autores: Storero, L.P.
Los caballitos de mar, Hippocampus sp. (Syngnathidae), presentan rasgos característicos: escasa flexibilidad, natación lenta y hábitos sedentarios. Por otra parte, en la bahía San Antonio (Río Negro, Patagonia), el ambiente en el que viven presenta corrientes intensas, amplio rango de fluctuación térmica y variaciones en la disponibilidad de alimento. Estas características ambientales limitarían la capacidad de desplazamiento y predación de la especie, forzando a la adopción de una estrategia alimentaria de tipo oportunista. Los objetivos del presente estudio fueron determinar la composición de la dieta del caballito de mar (Hippocampus sp.) en la bahía San Antonio a partir de contenidos estomacales e intestinales, y evaluar el comportamiento alimentario...

It is important to establish benchmark reef locations that are remote from centres of human activity and free from anthropogenic disturbances, against which human impacts elsewhere can be assessed and rates of recovery evaluated. Aldabra Atoll in the southern Seychelles, is free of anthropogenic disturbances and an ideal location in which to study reefs and adjacent ecosystems. It has further significance with it being in the middle of a region which has been classified as having a number of reefs at high risk (Bryant et al., 1998) and has been designated as a UNESCO World Heritage site.

Autores: Kouassi, A.M.; Issola, Y.; Messoum, F.G.
Les sédiments de la lagune de Fresco proviennent essentiellement des apports continentaux (des vents, des eaux de ruissellement et des rivières Bolo et Niouniourou) et océaniques. On distingue les sédiments grossiers dans les stations à forts hydrodynamismes (station 4 et 5) et les sédiments fins dans la baie (station 1, 2 et 3). Les stations situées dans les zones à faibles hydrodynamismes sont caractérisées par des particules fines qui sont relativement plus riches en métaux lourds que les sédiments des stations proches de la passe. Il en résulte que les différents paramètres chimiques mesurées tant dans les eaux que dans les sédiments de la lagune de Fresco pourraient servir de référence pour caractériser une lagune côtière tropicale non polluée.

Seychelles krab ziraf (Ranina ranina) fishery: the status of the stock
Provedor de dados: 20
Autores: Boulle, D.P.
The local commonly used kreol name for Ranina ranina is krab ziraf.  The krab ziraf fishery in Seychelles started functioning as a commercial fishery in 1986 when the resource was identified as potentially viable.  Prior to this time these crab stocks were unexploited.  In keeping with the Seychelles Fishing Authority (SFA) policy of monitoring catch and effort in new fisheries a research programme was implemented to assess the state of the Seychelles stock and determine the viability of the fishery as a whole. The objective of this report is to provide an indication of the state of the crab stock at the present fishing levels and give estimates of the standing stock biomass and the potential yield of the fishery. The biomass estimates give a range of...

The Namibian Fisheries Experience
Provedor de dados: 20
Autores: Goodisan, P.
As a consequence of the upwelling of the nutrient rich Benguela current the fishing grounds off the coast of Namibia were once the most productive in the world. Fishing activities off the coast of Namibia have always been organized into two quite separate in-shore and off-shore industries. In shore pilchard and anchovy dominate, whilst off shore hake and Horse Mackerel dominate. A highly integrated fish processing industry based on the in-shore pilchard has been built up at Walvis Bay, whilst of- shore long distance foreign fleets with few links to Walvis Bay have dominated the fishery.

Management Issues for the Sustainable Use of Lagoon Fish Resources
Provedor de dados: 20
Autores: Entsua-Mensah, M.; Ofori-Danson, P.K.; Koranteng, K.A.
Coastal lagoons form an integral part of marine fisheries and provide important spawning and nursery grounds for many fish species. The economic contributions of lagoon fisheries have not been given adequate consideration by fisheries authorities. Ghana's 550-km coastline includes over 90lagoons. These lagoons and their wetlands provide valuable products and services, which include supporting the fisheries, absorbing floodwaters and protecting biodiversity. They also serve as roosting, nesting and feeding sites for many species of birds. Through the support of the World Bank and the Global Environmental Facility, Ghana has designated five coastal wetland areas as Ramsar sites due to their importance as fishing areas and as roosting, nesting and feeding...

IODE National Report for Sweden
Provedor de dados: 20
In 1971 Sweden established an IOC Designated National Agency located in the Swedish National Board of Fisheries, Hydrographic Department. A major reason for the establishment of the DNA was the increasing awareness of the eutrophication problems in the Baltic. In 1985 the Hydrographic Department (including the DNA) was relocated to SMHI and changed the name to Oceanographic Laboratory. SMHI is the largest producer of oceanographic data in Sweden. In 1994 the Swedish Environmental Protection Agency appointed the laboratory as “National Data Host for Physical and Chemical Oceanographic Data". In 1998 the laboratory was reorganized into Oceanographic Services and made responsible for all marine monitoring data produced in SMHI.

Evidencia sedimentaria de tsunamis en la planicie aluvial de Villamil - Playas, Golfo de Guayaquil
Provedor de dados: 20
Autores: Chunga, K.; Quiñonez, M.F.
The Ecuadorian shoreline is considered highly susceptible to tsunamis events of tectonic origin due to its closeness to the Nazca and South America plates subduction zone. Since 1906, eight tsunamis events have been witnessed along this coast. All have been related to seismic activity (earthquakes between Ms 6.9 to 8.9) on or near the Ecuadorian platform. Such tectonic environment favours the generation and surge of tsunamis in this region. The study area is located in the outer area of the lower basin of the Guayas River, in what is referred as the Canton General Villamil Playas. Three cores were retrieved from the supratidal coastal plain around Villamil at different horizontal distances from the Pacific shoreline. Villamil 1 was cored at 1128 m from...

The current knowledge on the argentine continental shelf water masses is summarized in this paper. These water masses are characterized as a function of water types fed by the boundary currents and the modifications due to continental runoff, and water energy exchange with the atmosphere. Based on sea surface salinity distributions and the temperature-salinity characteristics, three masses are described: coastal waters, mid-shelf waters and slope waters. The main freshwater sources found along the coast are identified, as well as high salinity formation areas. The vertical stratification, mainly controlled by temperature, is analyzed along the annual cycle. The stratification cycle is mainly driven by the heat exchange between the atmosphere and the ocean....

Les pêches togolaises contribuant à 4% du PIB du secteur primaire sont exercées sur les plans d’eau maritime, lagunaire, fluviale, barrages et étangs piscicoles. Elles sont artisanales et industrielles en mer et exclusivement artisanales dans les autres pêcheries. Malgré leur relative pauvreté, les ressources halieutiques permettent aux pêcheurs de faire des prises permanentes en mer et en lagune et saisonnières dans les cours d’eau dont les estimations annuelles varient entre 12 000 et 17 000 tonnes. Elles créent environ 22 000 emplois répartis entre 10 000 pêcheurs (60% à temps plein) et 12 000 commerçantes et transformatrices de poissons. Tous ces emplois font vivre directement et indirectement environ 150 000 personnes....

Sampling the catch of fishing trawlers
Provedor de dados: 20
Autores: Okpanife, M. O.
This paper discusses the sample the sample design and estimation method for sampling the commercial catches of fishing trawlers.  The result of the application of the design to Nigerian Fishing Trawlers in 1981 is presented.  The conclusion that Nigerian Trawlers and not catching undersized fish as at 1981 is valid only on the assumption that there is no dumping of undersized fish at sea.

Preliminary studies of age and growth of bigeye tuna (Thunnus obesus) in the western Indian Ocean.
Provedor de dados: 20
Autores: Stequert, B.; Conand, F.
The age and growth of Bigeye tuna from the western Indian Ocean was investigated using both otolith and first dorsal spine. Microincrements, considered as daily depositions , were observed on transverse section of sagittal otoliths of 154 bigeye tuna (Thunnus obesus); they were counted to determine age and establish growth curve. The von Bertalanffy growth curve is FL = 303.9 (1 – e-0.000397 ( t+167.15)), where FL is fork length in cm and t in days. The fish reaches 58 cm at 1 year, 91 cm at 2 years and 120 cm at 3 years of age. We also studied growth by analysing marks on the first dorsal spine of 140 fish. For fish which are 1 and 2 years old, the results obtained with spine and otoliths are comparable, but they are different for older fish . 'Research...

Effects of Fish Culture on Water Quality of an Integrated Mariculture Pond System.
Provedor de dados: 20
Autores: Mmochi, A.J.; Dubi, A.M.; Mamboya, F.A.; Mwandya, A.W.
Six mariculture ponds were flooded with seawater since 1996. During this time the ponds were stocked with finfish (milkfish and rabbitfish), which were fed on locally produced fish feed. Some water quality parameters such as temperature, salinity and oxygen saturation were measured twice a day for three years (1998-2000), while nutrient concentrations were measured weekly for one year. Both nutrient concentration and oxygen saturation levels have shown a trend indicating eutrophication. Oxygen concentration changed from an average of 7.16 mg/l in October 1998 to 2.2 mg/l in March 2000 with a negative linear regression of 0.69 during the morning hours. From August 1998 to April 1999 dissolved inorganic ammonia concentration increased by 9 µg-at NIl, from...

Autores: Romdhane, M.S.; Chebil Ajjabi, L.; El Abed, O.
L’effluent des élevages de poissons renferme des concentrations plus élevées en nutriments dissous et en particules en suspension que celles présentes dans l’eau entrante. Cet état entraine par conséquent, des problèmes d’ordre environnementaux affectant les eaux côtières dues à l’eutrophisation et l’augmentation de la turbidité. Afin d’améliorer la qualité de l’effluent avant son déversement dans le milieu naturel, l’utilisation des bivalves comme filtre biologique est une alternative adéquate. Cette étude analyse la capacité de la moule Mytilus galloprovincialis de réduire les teneurs en sels nutritifs et la charge bactérienne dans les effluents de loups Dicentrarchus labrax en élevage.

The International Global Oceanographic Data Archaeology and Rescue (GODAR) Review Conference took place in Silver Spring, MD, USA from 12-15 July 1999. The Conference marked the end of the first phase of the GODAR project and was attended by more than 70 data managers and scientists. The Conference summed up the results of the first phase and provided guidance for future GODAR activities. Substantial amounts of additional historical data that still reside only in manuscript form have been identified by Member States as a result of the 6 regional GODAR meetings that have been held to date. The meeting concluded that the GODAR project should be continued and extended to possibly include additional variables such as sea level and ocean bathymetry.

The observations were made in captivity of the interactions between hermit crabs (Dardanus fucosus), anemones (Calliactis tricolor) and porcelain crabs (Porcellana sayan) all live together in two shells of gastropods collected in the region of Santa Marta. During 36 days were sporadic entries of the behavior of organisms, as well as video clips and photographs. We found new evidence in favor of relations of mutual and commensal type involving the three species, supported by the active transfer of porcelain crabs (Porcellana sayan), food and activities of the three species.

Instructions to the Marine Meteorological Observers, 7th Edition.
Provedor de dados: 20
The ocean meteorological program of the Weather Bureau has two separate and distinct parts. First, there is the daily service by radio. Owing to the need for brevity, the radio reports contain a limited amount of essential information. The daily weather reports from ships and islands reveal the conditions over the ocean; when assembled on a map, including continental reports, they give a picture of weather conditions existing momentarily over a large region. A collection of observations is immediately returned to the mariner by radio broadcast so that he may draw his own weather map on shipboard. By this process, the weather at the earth's surface is mapped and much can be inferred as to conditions above the surface. Formation and movement of storms are...

Autores: Ezzeddine-Najaï, S.; Chemmam-Abdelkader, Bachra; Kraiem, M.M.
Neuf cent vingt et un (921) spécimens du Brochet de mer (Sphyraena sphyraena) dont 366 mâles et 519 femelles ont été récoltés au Nord et à l’Est de la côte tunisienne.  La période de frai se déroule d’avril à août avec un maximum au mois de mai. L’analyse des rapports gonado–somatique (RGS) et hépato-somatique (RHS) montre que les réserves vitellines sont stockées au niveau du foie, ce qui permet de classer cette espèce parmi les poissons maigres. L’étude de la sex-ratio exprimée par mois et par classe de taille, montre que les femelles sont significativement dominantes tout au long de l’année, sauf pour les mois de mai et juin au cours desquels les proportions s’inversent significativement en faveur des mâles de taille comprise entre 25 et 29cm.

Autores: Díaz, Juan M.
Con base en colectas intensivas y en la bibliografía existente se hizo un listado de las especies de moluscos conocidas de la región de Santa Marta y Parque Nacional Natural Tayrona con anotaciones sobre sus preferencias de sustrato y rango de profundidad. De un total de 727 especies, 485 son gastrópodos, 214 bivalvos, 13 poliplacóforos, 10 escafópodos y 5 cefalópodos. La mayor cantidad de especies se encuentra en fondos de arena con fanerógamas marinas y de rocas sueltas (cantos, bloques) en aguas someras. La gran cantidad de especies en esta región se explica por la concentración de variados biotopos y rangos de profundidad en áreas reducidas y por factores histórico-biogeográficos particulares de esta región.

Battling for Corporate Accountability: Experiences from Titanium Mining Campaign in Kwale, Kenya
Provedor de dados: 20
Autores: Ojiambo, E.V.
The debate around the conduct of transnational corporations (TNCs) globally has been lively. Attention has focussed on the growing role of non-governmental organisations (NGOs) in ensuring that the TNCs become more accountable. NGOs influence the activities of TNCs in three crucial ways. First, through lobbying and encouraging others to lobby, they have brought pressure to bear on TNCs. Second, they have helped set and enforce regulations and standards to which, at the risk of financial loss, TNCs are keen to aspire. Third, NGOs have helped generate consumer concern to the extent that it is now a company’s long term competitive interest to act responsibly (Mulligan 1999:51).

Autores: Brown, D.R.; Leonarduzzi, E.; Averbuj, A.; Livore, J.P.
Argentine anchovy (Engraulis anchoita) eggs and larvae abundance distribution patterns in the Argentine northpatagonian littoral during January-April 2001 were analyzed. As the season progressed, a process of decline in the reproductive activity was observed. Larval growth and mortality rates were established. Age determinations were performed analyzing otoliths daily increments. The 0.43 mm day-1 growth rate average did not show space-time differences, fact attributed to the homogeneity of the thermal field. The 0.32 d-1 January natural mortality rate was determined by exponential decline. Mortality rates, estimated with the mortality-aggregation model, were considered dependent on the larval size. The value ranges (d-1) were 0.07-0.49, 0.05-0.61 and...

Seychelles tuna bulletin: First quarter 1992
Provedor de dados: 20
The number of purse seiners active in the western Indian Ocean averaged 53 during the first quarter compared to 41 vessels during the same period last year.  Fishing activity was high during the first half of the year with a record for the month of March of 55 licensed vessels. The fishing results for the first quarter were not as good as those previously recorded in the last three years, however there are still 28 logbooks outstanding at the time of publication.  Catch rates averaged 14.6 MT/day compared to 22MT/day in 1991 and 26MT/day in 1990.  The high number of vessels licensed during the first quarter can be attributed to increased number of licenses issued to French and Japanese vessles. 1992 has been a notably strong El Nino year, giving rise to a...

Dynamics Of Drupella Cornuspopulations On Kenyan Coral Reefs
Provedor de dados: 20
Autores: McClanahan, T.R.
In the central Pacific and western Australia the coral-eating snail Drupella cornus has been reported to exhibit large population increases or 'outbreaks' (&gt;10 snails/m2) that result in the loss or devastation of their coral prey. In Kenya, a large population increase of Drupella cornus was recorded from the early 1990's where D. cornus increased from a rare species in the mid 1980's to among the most common prosobranch snail by 1995 (~0.2 snails/m2). Population increases were most commonly observed in a section of reef that had experienced heavy fishing and loss of the durophagous predators such as triggerfish, but still maintained a high abundance of the branching coral Porites nigrescens. In unfished reefs, the population increases of D. cornus were...

Hill’s diversity indices were used as a measure of spatial diversity variance. A total of 95 species from 45 families were recorded. Gerres filamentosus, Pomadasys multimaculatum, Leiognathus equula, and Terapon theraps occurred commonly. Highest species richness (No = 68) and diversity (N1 = 31.09) was recorded at the entrance and Creek middle respectively. Most of the species overlap with the highest overlap index (L = 2.52) recorded between Cynoglossus gilchristi and Scombroides lysan.

Hoki, Macruronus magellanicus, is an important resource in the Argentinean multispecific southern demersal fishery. The species is distributed South of 46°S between the 50 and 200 meter isobaths. Thesouthern demersal fishery was almost nil prior to 1987, becoming more relevant toward the end of the 1980's. International fleets operating through several fishery agreement were those of the ex-Soviet Union,Bulgaria and Japan. Research on the abundance of hoki resources were initiated in the early 1970's; however, fishery research have been noticeably enhanced since 1992.

Autores: Pinto, M.A.; Lopes, S.
The fisheries sector plays an important role in the economy of Mozambique, contributing to 40-50 per cent of the country’s foreign exchange earnings. The extensive coast supporting diverse fisheries makes Mozambique a sensitive place for illegal, unreported and unregulated (IUU) fishing. This paper discuss the relation between IUU fishing and the surveillance capacity, the length of the coastal zone, the commercial value of the resources and the national fishing capacity of Mozambique.

Aquaculture Genetics Research In Malawi
Provedor de dados: 20
Autores: Ambali, A.
Aquaculture genetics research is carried out at the National Aquaculture Centre at Domasi, Malawi, by staff of the University of Malawi (UM) and the Department of Fisheries. The main species cultured are from genera Tilapia and Oreochromis. The genus Oreochromis was domesticated without proper identification of the various species especially in the subgenus Nyasalapia where three species (O. karongae, O. squamipinnis, and O. lidole) are difficult to identify before they reach breeding size. It is, however, observed that local fishers can identify these species using morphological characters. There have been no attempts to carry out deliberate domestication selection in the small-scale farms with the prevailing practices probably leading to deterioration of...

Autores: Degnbol, P.; Nielsen, J.R.; Viswanathan, K.K.; Ahmed, M.
Current fisheries management approaches based on centralised government intervention have proven inadequate to deal with the present management and cannot meet its objectives including reverting stock depletion, resolving user-group conflicts, increase profitability and prevent social disruption. There is no easy solution to this problem. New institutions enabling fishing communities to deal with present pressures are needed. Fisheries management is however still largely government-driven although experiences worldwide show that various forms of partnership between government, industry and fishers strengthen management and produce results. Such partnerships have become known as co-management.

The programme also provides technical information for theplanning of wetland activities and oversees developments in wetlands. About 10% of Uganda's total land area, 205,000 km2, is occupied by wetlands andhistorically these areas were referred to as wastelands. The belief that wetlands, especiallymarshes, are a major source of diseases like malaria and bilharzia has discouraged theirutilisation.

Lakes water quality monitoring and management programme in developing countries

Developing Countries face an array of traditional and modern lakes water quality problems ranging from faecal contamination to toxic chemicals. Moreover, they do so in an economic environment that is severely restricted, an institutional environment which is often poorly structured, and for which the modern scientific knowledge base is frequently poorly understood and applied. Agencies in many developing countries recognize this as major impediment to sustainable development, especially as water quality has become one of the leading economic issues for the purposes of development and investment. Generally water quality programmes tend to suffer from traditional approaches, both of methodology and legal/administrative. The Consequence is that many...

Over the last two decades, the number and complexity of international cooperative programmes has increased. We are just completing WOCE, and JGOFS, but there is the IGBP, CLIVAR, GOOS, GCOS and GTOS among others. Many of these programmes originated in the research community. Using WOCE as an example, the programme organized 13 Data Assembly Centres (DACs) whose jobs were to assemble, quality control, and prepare the data for the final archive. IODE data centres participate in 4 of these DACs while another 4 DACs (non-IODE) handle data that are also managed by many IODE data centres, thus duplicating the effort. The remainder of the DACs dealt with data outside of traditional IODE data centre responsibility.  The TOGA/TAO centre at PMEL is an example of a...

A traditional area of success for IODE has always been its Capacity Building Programme. Since the establishment of the Programme in 1961 many training courses and workshops have been established, missions to member states undertaken and through these training efforts the network has reached a total of 65 NODCs in 2002. However, despite these 4 decades of training the IODE Secretariat ‘discovered’ in 1998 that there existed no standard curriculum or even training material for ocean data and information management. Although an effort had been made in this direction with the OceanPC initiative, this had never been expanded to a more comprehensive training system and remained ‘only’ a software toolbox.

The study reported here sought to investigate the effect that the dredging of the harbour basins and the entrance channel has had on sediment deposition rate into the Dar es Salaam harbour. Echo-sounding was carried out along berths No 2, 3, 4, 6, 7 and 8 as a means of detecting changes to their bathymetry in the four years since 1998, when the dredging commenced. Concentrations of transported sediments into and out of the harbour were determined using sediment traps. Short-term measurement of waves and currents were also carried out. Sediment traps, a wave-gauge and a current-meter were deployed in the entrance channel during the South East and North East monsoon seasons respectively. Our results reveal that the sedimentation rates after improvement of...

Numerical Simulation of the Influence of Mean Sea Level Rise on Typhoon Storm Surge in the East China Sea.
Provedor de dados: 20
Autores: Gao, Zhigang; Han, Shuzong; Liu, Kexiu; Zhrng, Yunxia; Yu, Huaming.
In this paper, ECOMSED (Estuarine Coastal Ocean Model with sediment transport) model is employed to simulate storm surge process caused by typhoon passing across East China Sea in nearly years. Capability of ECOMSED to simulate storm surge is validated by comparing model result with observed data. Sensitivity experiments are designed to study the influence of sea level rise on typhoon storm surge. Numerical experiment shows that influence of mean sea level rise on typhoon storm surge is non-uniform spatially and changes as typhoon process differs. Maybe fixed boundary method would weaken the influence of mean sea level rise on storm surge, and free boundary method is suggested for the succeeding study.

IOC and IODE have since long recognised the need for training courses, aimed at promoting knowledge on adequate management of marine and coastal data and at sharing the experience in this field between the countries involved. A first course of this type for the region was held in 1991 in Bogota, Colombia (IOC Training Course Report 14). It had as its main goals the promotion of methodologies and technologies for the management of marine data and information in National Oceanographic Data Centres, as well as the promotion of the system for International Oceanographic Data and Information Exchange, IODE of IOC. The training workshop in Rio Grande was the second opportunity of this type for the countries of the region.

Se observaron tres tipos de campos: El primer tipo parece tener la función de un canto de apareamiento; el segundo está, probablemente, relacionado con la defensa del territorio y el tercer tipo de canto se observa solamente inmediatamente ante la introducción a la postura de los huevos. A menudo se observan cantos alternos entre...

Proposition d'une echelle macroscopique de maturite sexuelle des femelles de poulpe Octopus vulgairs (Cuvier, 1797)
Provedor de dados: 20
Autores: Ould Mohamed Fall, K.; Inejih, C.A.O.
La présente échelle macroscopique de maturité sexuelle chez les femelles de poulpe repose sur une étude histologique des ovaires. Les individus échantillonnés sont classés suivant l'échelle de maturité sexuelle de Dia et Goutschine (1990). Les caractères morphologiques externes des ovaires sont par la suite décrits avant de procéder au prélèvement d’un échantillon qui va servir à l’étude histologique. Après observation microscopique, une correspondance est établie entre la réalité microscopique et les caractères morphologiques pour l’obtention d’une nouvelle échelle. Cette nouvelle échelle à six stades que nous proposée reflète un bon état de la maturation des ovocytes dans l'ovaire.  The sexual maturity scale for the females of Octopus vulgaris is...

State of the stocks and change in the abundance of demersal fisheries resources in the member countries of the CSRP
Provedor de dados: 20
Autores: Gasceul, D.; Laurans, M.; Sidibe, A.; Barry, M.D.
This communication presents a synthesis of the work undertaken within the framework of the FIAS project, by the “Single-species Analysis” module. This work focuses on statistical analyses of commercial fishing and the data from scientific trawling surveys, in order to deduce the current state of exploited stocks and to better understand the ecosystems of the sub-region. This relates to the analyses of about 20 stocks, distributed in the waters of the various countries and covering a broad range of ecological characteristics. Three approaches were used: (1) analyses of a time series of estimates of abundance indices obtained from GLM-type methods applied to survey or commercial data; analysis of a time series of catches and catches per unit of effort used...

Autores: Arias, J.; Zea, S.; Newmark, F.; Santos-Acevedo, M.
As a contribution to the biological knowledge about the sea fan Gorgonia ventalina and the use of this information as a tool to generate conservation and management strategies for this threatened species, a study about its annual growth rate, in different reef areas in Santa Marta and the National Natural Park Tayrona in the Colombian Caribbean took place. Manual measurements of 35 colonies were analyzed and images of 11 colonies were recorded in the beginning and in the end of the field stage. The annual growth rate varies among colonies and areas where measurements were taken. The average annual growth rate obtained with both of the methods was high and oscillated between 7.6 and 8.1 cm/year in height and between 6.9 and 8.3 cm/year wide. The total area...

Geomorphology of the Kenyan Coast: Not as a Result of Sea-Level Change Alone
Provedor de dados: 20
Autores: Abuodha, P.A.W.
The coastal setting and the geology control the geomorphology on the Kenyan coast. The evolution of the physical environment has also been influenced by climate, wave and tidal regime, sedimentation and river discharge. The shore terraces of Kenyan coast correspond to eustatic movements of sea level. There seems to be evidence of a high water level during the late Pleistocene. For the lower terraces a Holocene age is suggested. During the Pleistocene, sea level fluctuations associated with glacial / interglacial phases left well developed raised platforms and beaches. The Kenyan coast has a strong tectonic influence and it is difficult to describe the coast in terms of emergence or submergence only. It can therefore be concluded that the geomorphology of...

The management and directions for future research on Lake Victoria multispecies fisheries
Provedor de dados: 20
Autores: Okemwa, E.
A brief review is presented on some of the measures taken to manage Lake Victoria multispecies fisheries. It is suggested that management enforcement is not working. The linkage between research, policy making, industry and artisanal fishery is considered. The paper examines how the whole process of taking management decisions might be modified to take into account the realities of life in the riparian states around the lake and of the complexities and uncertainties of multispecies fisheries. Research and assessment are considered. Understanding the multispecies fisheries and characteristics of contemporary fisheries management are described. Recommendations for future research are given.

Influencia de las interacciones con el factor Año en los índices anuales de abundancia obtenidos por modelos lineales generales utilizando datos de Captura por Unidad de Esfuerzo
Provedor de dados: 20
Autores: Hernandez, D.R.; Perrotta, R.G.
The problem in the definition of a relative annual abundance index using a General Linear Model is posed. The possible factors generating changes in the catch per unit effort (CPUE) are discussed and the parameterization of the model is analyzed, in particular the Sigma-restrictive parameterization. This report considers the problem caused by the presence of interactions of first order that include the factor Year in the model. It has been mathematically demonstrated that in the presence of these interactions, the index series is not proportional to the abundance annual mean of the resource. An approach of practical order to evaluate the possible effect of the interactions that include the factor Year in the index is considered using the percentage of...

The Spanish-Moroccan “Crisis” and the Future of Euro-Med Relations: Farce or Harbinger of Things to Come?

Autores: Maddy-Weitzman, B.
At first glance, the Spanish-Moroccan confrontation over an uninhabited rock outcropping, 200 meters off the Moroccan Mediterranean coast, seems like something conjured up from a Marx Brothers movie. However, the triggering of nationalist passions on both sides of the Straits of Gibraltar, the speedy support by the two countries’ respective allies (the European Union for Spain, and the Arab and Islamic states, apart from Algeria, for Morocco), and the swift and decisive flexing of Spanish naval muscle, indicate that there is more to the matter than initially meets the eye. The fact that both countries have agreed to an American-brokered stand-down and initiated a round of high-level diplomacy is a tribute to mutual good sense. Nonetheless, the brief storm...

Argentine hake Merluccius hubbsi represents nowadays the main fishery resource of the Argentine Sea, in spite of the fact that the percentage of captures related to total fishery production has fallen down 30% in the last decade. The abundance and distribution of hake eggs and larvae in an intense spawning area in front of Isla Escondida (Chubut province), are analyzed. This phenomena was studied from a comparative-historical point of view allowing to apppreciate the evolution of a resource at present undergoing an overfishing pressure, capable of pushing it to collapse. Since 1973 maximum egg densities diminished and, if total egg production is considered a reliable index for recruitment prediction, no signs of overcoming stocks can be seen. On the other...

Provedor de dados: 20
The IOC Committee on International Oceanographic Data and Information Exchange held its Twentieth Session (IODE-XX) at the China People’s palace Hotel in Beijing, China between 4 and 8 May 2009. The Session was attended by 67 participants from 35 IOC Member States and 4 organizations. The Session’s highlights included: (i) IODE Ocean Data Portal: good progress was reported in the development of the IODE ODP Project but more NODCs should contribute as data providers. IODE must also work with other portal projects, such as SeaDataNet, to ensure interoperability between these different systems as NODCs cannot be expected to install multiple portal applications; (ii) OBIS: the committee expressed its opinion that OBIS should become part of the IODE programme...

Autores: Leadbetter, A; Raymond, L.; Chandler, C.; Pikula, L.; Pissierssens, P.; Urban, E.
This "Cookbook" has been written for data managers and librarians who are interested in assigning a permanent identifier to a dataset for the purposes of publishing that dataset online and for the citation of that dataset within the scientific literature. A formal publishing process adds value to the dataset for the data originators as well as for future users of the data. Value may be added by providing an indication of the scientific quality and importance of the dataset (as measured through a process of peer review), and by ensuring that the dataset is complete frozen and has enough supporting metadata and other information to allow it to be used by others. Publishing a dataset also implies a commitment to persistence of the data and allows data...

Sudanese Coastal Water  Composition and Some Environmental Aspects
Provedor de dados: 20
Autores: Ali, Aasim.
Red Sea water samples were collected from four stations in the Sudanese coast at depth of 10 m during July 2011 and analyzed for major ions and trace metals in order to determine their insitu concentration, their distribution patterns, and level of heavy metals contamination in the Sudanese coastal water. The data of the analysis was used in the preparation of the Red Sea artificial water which was used to study how salinity affects the photooxidation of 1,8-dimethylnaphthalene (1,8-DMN) and the water-soluble fraction (WSF) from Norwegian crude oil. The results show a small range of spatial variation for Na+, Mg2+, Ca2+, Cl−, K+, and SO2−4 . Also, the concentration of Na+, Mg2+, Ca2+, Cl−, and SO2−4 in the Sudanese coastal water is high compared to all...

Seychelles tuna bulletin: third quarter 1990
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean increased from a low of 41 at the end of the last quarter to 45 vessels in September. Fishing results improved slightly with daily catch rates for the third quarter averaging 22 MT, increasing from 17.7 MT/day in August to 31.5 MT/day in September.  These results are considerably better than those for the same period last year when it averaged 16 MT/day. The fishing pattern for the third quarter showed that fishing effort was concentrated between 5 degrees north and 5 degrees south of the Equator in the vicinity of the Northern sector of the Seychelles EEZ. Fifty five percent of the third quarter catch was made up by skipjack tuna compared to 58% for the second quarter.  This is partly due to...

Heterogeneity And Collective Action For Effort Regulation : Lessons From The Senegalese Small-Scale Fisheries
Provedor de dados: 20
Autores: Platteau, J.P.; Gaspart, F.
Much attention has recently been paid to the potential influence of inequality or heterogeneity on people’s ability to organize collectively, particularly with respect to management of local-level natural resources. Speaking generally about this issue makes little sense in so far as heterogeneity or inequality is obviously a multidimensional phenomenon the different facets of which may carry varying implications for collection action capacities. Important among these different facets are : income or wealth (or productive capital) inequality, inequality in access to alternative income opportunities, social stratification or differential positions in the local power structure, skill disparity, ethnic and cultural heterogeneity, and diversity in techniques...

Evaluation of the Status of the Namibian Hake Resource (Merluccius spp.) Using Statistical Catch-at-Age Analysis
Provedor de dados: 20
Autores: Kirchner, Carola; Kainge, Paul; Kathena, Johannes.
Namibian hake is the most important fish resource in Namibia. This monograph is a compilation of all the hake data, historic and recent, that has been used to inform stock assessment and management since the late 1970s. It presents the statistical catch-at-age analysis used to evaluate the state of the Namibian hake resource under different assumptions. This analysis treats the two hakes, Merluccius paradoxus and M. capensis, as a single stock. The data and modeling show that the stock has not as yet recovered to its maximum sustainable yield level, despite foreign fishing effort having been removed in 1990. Best estimates suggest the current stock to be roughly 20% of pre-exploitation levels; however this figure is sensitive to model assumptions. Signs...

La dynamique de l'environnement dans le sud-est du Togo: essai de cartographie
Provedor de dados: 20
Autores: Houedakor, K.Z.
RESUME Le Sud-Est Togo, l'une des régions les plus densément peuplées du pays, connaît une exploitation agricole intense depuis la période coloniale. Aujourd'hui, cette exploitation s'intensifie avec la croissance de plus en plus élevée de la population. L'évolution du milieu naturel qui est le reflet de la dynamique de l'environnement, est le fait de l'homme et des facteurs physiques dont le plus important est l'eau. L'action humaine s'imprime dans le paysage par l'extension des champs de vivriers, des plantations et par la disparition de la végétation naturelle. Le plateau de terre de barre aux formations argileuses, et la bande littorale sableuse portent les marques de l'action humaine. Celles-ci sont visibles surtout par la dénudation des sols,...

The aim of this work was to analyze hydrological condition variations in Cienfuegos’ Bay in 2011 and its possible  influence in life cycle and distribution of the green mussel  Perna viridis. The hydrological parameters in the bay are described  according to the campaigns performed in February, May and November. Samples from two levels (surface and bottom) were taken, in  order to get water temperature, salinity and dissolved oxygen. The results show the climatic seasonality influence (dry and rain) both  in spatial as well as in vertical distribution of the observed parameters. The mean concentrations of the analyzed hydrological  markers were in agreement with the NC 25: 1999 requirements of good quality water  for fishing use. The observed hydrological...

In order to study the benthic ecology of the “Messioua banc” (30 NM east off Zarzis, Southern Tunisia), a traditional Tunisian sponge fishing ground, four marine campaigns were conducted with the R/V “Hannibal” from October 2000 to August 2001. The objectives of three of these campaigns were field validation, focusing on the sampling of the Posidonia oceanica meadow and of the sponge population. However the goal of the fourth one, with the use of a multi-beam sonar SEABAT 9001 (Reson Co.), was the mapping of bottom of the surveyed area and the scanning of the Posidonia meadow and its sponge population. The field work allowed the study of sixteen stations covered by a dense meadow extending from 21 to 33 m depth, which present the highest density of...

Port-Reitz Creek (04°04' S, 39° 39' E) is one of the two main tidal mangrove fringed creeks found in Mombasa Island. It experiences semi-diurnal pattern of two low and two high tides every 24 hour cycle. Six stations were strategically positioned along the length of the creek and sampled for heavy metal (cadmium, copper, iron and zinc) content during July 1998. A peak of Cu and Zn (87 and 235 µg/g dry weight respectively) was observed at Station 2, which borders a steel factory and fish-processing firm. A correlation matrix showed close distribution pattern between Zn and Cu (r = 0.67) and between Fe and Cd (r = 0.62). A peak for Cd (6 µg/g dry wt) was observed at Station 3. Fluvial input in the creek was a source of Cd, Cu, Fe and Zn. Cd and Zn were of...

Taxonomic challenges and distribution of gracilarioid Algae (Gracilariales, Rhodophyta) in Tanzania
Provedor de dados: 20
Autores: Buriyo, A.S.; Oliveira, E.C.; Mtolera, M.S.P.; Kivaisi, A.K.
This paper reviews the taxonomical literature of the gracilarioid algae from Tanzania, and provides information about their ecology and distribution based on an intensive regime of local collection. Its aim was to provide names, even if on a preliminary basis, for local gracilarioid taxa. Our revision shows that species misidentification is widespread and that some species are in need of further critical taxonomic study. Nine species of Gracilaria are reported in the region, including one unidentified Gracilaria or Gracilariopsis.

En diferentes zonas climáticas de Colombia se hicieron medidas del crecimiento del limbo y de la velocidad del ascenso de agua por el tallo de Coffea arabica L. y Citrus aurantium sinensis Engler. En la época de lluvia, la velocidad máxima diaria del ascenso de agua se disminuyó con la altura, a saber, más en Citrus que en Coffea, bajo factores ambientales idénticos. Al contrario, al final de la época seca, se midieron los máximos del transporte de agua en alturas de 1250 ms (Citrus) y 1850 ms (Coffea) respectivamente. En tiempo de sol, las velocidades máximas estaban en Citrus esencialmente, en Coffea solo insignificantemente mayor que en días nublados. El máximo crecimiento del limbo alcanzó Coffea en 1850 ms y Citrus en 1250 ms de altura. Del punto de...

Notas sobre la ecología de los lagartos de la isla Malpelo, Colombia. Observaciones de dos de las especies endémicas de lagartos de la isla Malpelo ofrecen características poco conocidas de su historia natural, ecología y estado poblacional. Anolis agassizi, el lagarto más abundante y ampliamente distribuido, se alimenta principalmente de insectos y excretas de aves marinas. Duerme sobre rocas grandes, en las paredes de los cerros o sobre estructuras construidas por el hombre y, aunque no defiende sitios de percha como la mayoría de Anolis, muestra predilección por sitios elevados en donde, entre otras actividades, realiza sus cópulas. Diploglossus millepunctatus, el lagarto de mayor tamaño corporal y menor abundancia, es un depredador-oportunista y...

Beaks of Loliginid squids have very similar morphological features making identification of the species to be quite difficult. A new metodology to identify species from the relative growth of some parts of the beak is presented. Samples of Loligo gahi and Loligo sanpaulensiswere obtained from ten reserch cruises of RVS "Dr. Holmberg" and "Captain Oca Balda" and eight commercial landings at Mar del Plata Port during the period 1992-1993. The results obtained using the new metodology (Metric Discriminant Criterium)were compared with those resulting from the application of the Fisher's Lineal Discriminant Criterium. Both mantle length - rostral length and total weight - rostral length relationships, corresponding to each species were fitted. Either upper or...

Autores: Boschi, E.E.; Spivak, E.; Martorelli, S.R.
Adults of the palaemonid prawn Palaemon macrodactylus Rathbun, 1902 were reported for the first time from the southwestern Atlantic waters. Males and ovigerous females were collected in Mar del Plata harbor (38 degree 03' S; 57 degree 31' W), Argentina; larvae obtained from one of the collected females were reared in the laboratory until the juvenile stage. The geographical range of P. macrodactylus was previously restricted to the Pacific Ocean: it was originally described in Japan and has been reported as an invasive species in the western coast of USA in the 1950's and in Australia in the 1970's. Recently, this prawn has been also reported from European waters.

Participation in Fisheries Management for Improved Livelihoods of Artisanal Fisheries Communities in West Africa
Provedor de dados: 20
Autores: Cacaud, P.; Lenselink, N.
A number of trends can be identified which are conducive to increased collaboration between fishers and government in fisheries management measures, as well as for an increased attention for livelihoods aspects. On the fishers’ side there are already existing (though not generally ‘traditional’) rules and committees governing fishing and there is an increasing awareness in communities for the need to protect stocks. The government has increasing interest in artisanal fisheries and already existing processes of consultation with fishers for the elaboration of management measures. In addition there are ongoing decentralisation processes which promote sharing of responsibilities with local institutions for the management of natural resources and already...

Estero Ciego beach is located in the tourist area in Holguín province, northeastern coast of Cuba. At present, the beach suffers an erosion process, being observed the appearance of extensive rocky surfaces in the eastern half of the beach as well as a marked deficit of sand in the coast. The objective of this study is to define the engineering solutions required to improve the aesthetic and use conditions of the beach. As main action it is proposed the artificial nourishment of sand, since it constitutes a solution that creates the aesthetic conditions rapidly. As a complement to guarantee the beach stability for a longer period of time, it is also intended to reduce part of the rocky surface that presently exists on the coastline in the eastern half of...

Postlarvae and juveniles of Farfantepenaeus spp. and Xiphopenaeus kroyeri were collected at Boca de la Barra (Ciénaga Grande de Santa Marta), by means of a channel net that orientates with the tide. Sampling was carried out every two weeks for ayear (February 1998 – February 1999), so that each sampling date corresponded to full and new moon alternatively. Farfantepenaeus spp. postlarvae tended to appear in the dry season and with significantly greater abundance during full moon (Mann-Whitney test, P&lt;0.05). Juveniles showed a different pattern: there were significant differences between seasons (Mann-Whitney test, P&lt; 0.05) with higher concentrations in the rainy season, but not so between moon phases (Mann-Whitney test, P&gt;0.05).

The pollution of marine sediments by trance elements in the coastal region of Togo caused by dumping of cadmium-rich phosphorite tailing into the sea
Provedor de dados: 20
Autores: Tobschall, H.J.; Gnandi, K.
The marine coastal sediments from Togo have been analysed for the trace elements Cd, Cr, Cu, Ni, Pb, Sr, V, Zn and Zr to ascertain the geo-ecological impact of dumping of phosphorite tailings into the sea. Trace element concentrations ranged from 2-44 ppm for Cd, 22-184 ppm for Cu, 19-281 ppm for Ni, 22-176 ppm for Pb, 179-643 ppm for Sr, 38-329 ppm for V, 60-632 ppm for Zn and 18-8928 ppm for Zr. Regional distribution of trace elements in the marine environment indicates that the concentrations of Cr, Cu, Ni, Pb, V, Sr and Zn increase seawards and along the coastal line outwards of the tailing outfall, whereas Cd and Zr showed reversed spatial patterns. Sorting and transport of phosphorite particles by coastal currents are the main factors controlling the...

Dans notre étude taxonomique et après une présentation de la famille de Blenniidae, nous avons abordé une première tentative de discrimination entre les espèces moyennant des caractères morphologiques méristiques et morphométriques. Toutefois, le chevauchement signalé au niveau de ces caractères rend la tache difficile. Dans le but d’obtenir une meilleure séparation nous avons intégré les variables biométriques dans une méthode multidimensionnelle (ACD) qui nous a permis une meilleure discrimination des espèces. En se basant sur ces résultats nous avons établi des fiches...

Morphological development of the mouth and improvement in feeding ability in the early larval stages of red porgy, Pagrus pagrus (L.)
Provedor de dados: 20
Autores: Aristizabal, E.O.
The appearance, ossification and growth of cartilaginous structures of the mouth in early larval stages of laboratory reared red porgy Pagrus pagrus, were examined. At the time of mouth opening, red porgy larvae are equipped with the fundamental components of the oral cavity to allow the sucking motion for acquiring food. During the initial feeding stage, from day 5 after hatching (AH) to day 7 AH, the hyoid and lower branchial archs were completed, and the head length and other structural elements, like the ceratohyal-epihyal cartilage, increased rapidly. These events intensified sucking mechanisms by increasing the amount of ingested rotifers. After day 13 AH, the presence of the bony premaxilla and angular, the ossification of the Meckels cartilage and...

Land use in Kenya
Provedor de dados: 20
This book exposes the key land use and environmental problems facing Kenya today due to lack of an appropriate national land use policy. The publication details how the air is increasingly being polluted, the water systems are diminishing in quantity and deteriorating in quality. The desertification process threatens the land and its cover. The soils are being eroded leading to siltation of the ocean and lakes. The forests are being depleted with impunity thus destroying the water catchments. The savannas and grasslands are undergoing de-vegetation through overgrazing, charcoal burning and other poor land use practices leading to desertification. The book also reveals the underlying causes of the deterioration of the life support systems (air, water and...

Autores: Abbas, M.M.; Shakweer, L.
The effect of temperature, pH and trace elements concentration in the ambient water on the uptake and accumulation of Cu, Zn, Ni and Pb in various organs of fish and parts of aquatic plants of Edku Lake were studied. It was found that higher water temperature and lower pH during summer increased the rates of trace metals uptake by the most common fish species Oreochromis niloticus. The concentrations of Cu, Zn, and Ni in the various organs of fish were affected by the concentrations of these elements in the water. Cu, Zn, Ni and Pb attained higher concentrations in the roots of Eichormia crassipes if compared with their concentrations in the other parts of this aquatic plant. Sex of fish can be considered as an important factor affecting the accumulation...

The New Design of IOTC’s Database
Provedor de dados: 20
The original IOTC database was developed in Microsoft Access, a desktop DBMS. As the size and number of simultaneous users connected to the database grew, it became obvious that it was necessary to shift the database to a Client/Server system, capable of attending high-load requests from concurrent users over a network. In addition, during the normal use of the database several limitations of the original design were detected, particularly in terms of framework rigidity. To address these problems, a new design based on the Client/Server paradigm was implemented. This document describes the new design, and discusses the concepts and objectives on which the new design was based. The new data base design was implemented on Microsoft SQL server and is...

Between September 2001 and September 2002, Ultima Esperanza fjord and Señoret Channel were surveyed, sailing from Puerto Natales. Information on abundance, structure and distribution of aquatic and land birds observed during the sail is presented. We found 30 species of aquatic birds and 3 land birds.: 1 In Danger, 3 Vulnerables and 1 Insufficiently known. Our analysis shows that these fjords contained one of the biggest winter abundance of birds of the region and is a nesting area for many species. Furthermore, we proposed that the fjord constitute a core area for aquatic birds in summer when fresh water lagoons and ponds get dry. Finally, we make special reference to the need to implement a management plan in the area.

The objective was to use the synoptic capability of NOAA-AVHRR images, and the physical variables inferred from them, in order to achieve spatial and temporal analysis that may allow correlating the satellite variables with oceanographic processes and biological or fishing data. Methodologies of image processing were developed to make possible the use of AVHRR information for the standardized and reliable generation of Sea Surface Temperature (SST) images (using bands 3 to 5 in the thermal infrared), and water reflectance images (using optic bands 1 and 2) as an index of surface turbidity in coastal zones. A methodology was also generated in order to obtain gradients images derived from SST images, which allows the identification of oceanographic fronts....

Gender plays an important role in the artisanal fisheries, therefore it critical for both men and women to participate fisheries management. This paper analyzes gender responses to introduced or enhanced fisheries regulations and constraints to compliance so as to facilitate gender participation in the management of Lake Victoria in Kenya. Both primary and secondary data have been used. Results indicated that in Lake Victoria, there is a clear-cut division of labor differentiated by gender, which is culturally defined. Men and women respond to management measures differently due to differentiated roles and space they operate in. Poverty emerged as a constraint to both men and women but affecting the women much more due to lack of economic and status...

Consideraciones sobre la explotación del mejillón (Mytilus platensis)en la costa bonaerense. Resultados de la campaña de prospección del "Banco Faro Querandí" (junio 1981)

Autores: Lasta, M.L.; Parma, A.M.; Pascual, M.S.; Zampatti, E.A.
The fishing of the mussel (Mytilus edulis platensis)off the Buenos Aires coast was alternatively carried out over two main grounds: "Faro Querandí" and "Quequén". The fluctuations of fishing periods on these grounds must have been determined by economic considerations. An abandoned bed may be considere, for practical purposes, depleted.The understanding of the dynamics of this spatially distributed stock could enable us to link more closely the biological cycles with those of the fishing activity. Rotative fishing is suggested as a managment strategy for this fishery.

Coastal Aquaculture Developments in Tanzania: Sustainable and Non-sustainable Experiences
Provedor de dados: 20
Autores: Bryceson, I.
Coastal aquaculture of seaweeds and prawns has developed in  Tanzania during the past two decades. Farming of Eucheuma seaweeds commenced in 1989 along the east coast of Zanzibar and it has since expanded to other areas. This form of aquaculture does not pollute the environment with feeds, wastes or other chemicals, although there are some negative interactions causing inhibition of surrounding biota, but which appear to be relatively mild. Monoculture may result in some self-inhibition and disease vulnerability over time. The socio-economic impacts of seaweed farming was initially overwhelmingly positive, providing income to women from relatively poor remote villages. Annual production reached 7000 tonnes constituting an important earning of foreign...

Structure and Dynamics of demersal assemblages on the continental shelf and upper slope off  Ghana, West  Africa
Provedor de dados: 20
Autores: Koranteng, K.A.
Using two-way indicator species and detrended correspondence analysis, species on the continental shelf and upper slope of Ghana were classified into 6assemblages. The structure of the assemblages is determined primarily by depth and type of sediment on the seabed. There are clear faunal discontinuities around 30-40, 100, and 200m depth. The dynamics of the assemblages are influenced by physico-chemical parameters of the water masses, mainly temperature, salinity and dissolved oxygen, which are periodically modified by the seasonal coastal upwelling that occurs in the area. The observed changes in the composition and relative importance of species in the assemblages can be related to increased fishing activity and environmental forcing.

In August 1996 acoustic methods were employed to estimate mackerel (Scomber japonicus) abundance in the Buenos Aires, Argentina shelf area of "El Rincón" (4,287 mn2), located between 39°- 40° 30' S. Results showed a biomass estimate of 77,260 t. ASIMRAD EK-500 equipment operated with a 38 KHz split-beam transducer was used. Midwater fishing trawls were employed to identify echotraces and to collect mackerel samples.Trawls 4 and 5 were the most successful. Samples included only adult fish  (310-470 mm Lt and ages ranging 2-11). Length and weight growth parameters and mortality rates were estimated. Analysis of the stomach contents revealed that mackerel was feeding exclusively on zooplankters over 2 mmlength. The analysis of the characteristics (dimensions...

Proceedings of the Workshop on the Management of the Shallow Water Shrimp  Fishery of Tanzania

The fishery is presently comprised of an industrial trawler component and an artisanal component. During 1989 there were sixteen trawlers engaged, two belonging to the parastatal Tanzania Fisheries Corporation (TAFICO) and the rest being foreign-owned. The landings from these vessels included 974 tonnes (whole weight) of shrimp and 1,069 tonnes of fish by-catch. Almost all the shrimp were exported. The wholesale (fob) value of the shrimp was probably in the order of US$ 5.5 million. On the basis of data collected during a socio-economic study undertaken immediately prior to the Workshop, the estimated landings by the about 859 artisanal fishing units in 1989 was 1,212 tonnes of shrimp suitable for export, along with over 3,000 tonnes of fish.

Lake Victoria’s Nile Perch Fish Cluster: Institutions, Politics and Joint Action
Provedor de dados: 20
Autores: Mitullah, W.
The collective efficiency model contends that joint action is essential for coping with new challenges. This paper discusses how enterprises in the Lake Victoria fish cluster operate, interact and address common challenges facing the industry. It suggests that the lack of effective institutions and the existing power relations explain the inability of the cluster to respond effectively to recent crises. Both the Co-operative Society and the Fisheries Department are weak, whereas the existing welfare based associations merely exploit social capital in sub-ethnic groups. These groupings have not transcended welfare concerns into the economic realm, and their potential for taking strategic joint action is limited. The cluster’s strongest joint action has been...

Autores: Clarke-Marshall, M.; Ghouralal, N.
Human activities adjacent to and within a wetland, influence its ecological status. An understanding of the social and economic conditions in the communities within and adjacent to the Godineau Swamp is fundamental to its sustainable use. The effective functioning of wetland resources is centered on the sustainable management of human activities and traditional uses. The Godineau Swamp is the second largest wetland system found on the Gulf of Paria of Trinidad. Traditionally the wetland has supported a fish and shellfish industry and provided land for agriculture livestock farming and housing. Oil exploration has taken place in the Godineau Swamp for the last fifty years and the Swamp continues to provide several opportunities for ecotourism.

Stripped weakfish is one of the ensemble of species known as “variado costero” most frequently landed. Considering that fact, determination of abundance indices is particularly relevant to apply assessment models and make recommendations to allow for a proper fishery management. The aim of this study was to obtain those indices of the species derived from research cruises carried out in the Argentine-Uruguayan Common Fishing Zone AUCFZ area (34°S-39°S) in the 1993-2006 period. In order to improve the traditional estimate accuracy modeling was used. To formulate the general linear models year, stratum, length, bottom salinity, depth factors and population data such as mean size and juveniles percentage were used.

The sponge communities at four locations on the east coast of Bahía de Cochinos were surveyed in October 2002. At each location, sampling sites were established in the ecological zones of patch reef (3 m), shallow terrace (6-10 m), and deep terrace (15 m). The line-transect method with a 10 m line as sampling unit was used to measure sponge bottom coverage, and a 1 m square grid was used to quantify sponge community density. Species heterogeneity and species richness indices showed variability among sites and tended to increase with depth. Thirty species belonging to 19 families and 21 genera were found. The most common species were: Mycale laevis, Aplysina cauliformis, Cliona aprica, Aplysina fistularis, and Ectyoplasia ferox, which comprised 48% of the...

La présente étude a pour objectif la détermination de la taille de première maturité sexuelle, l’estimation de la fécondité ainsi que la taille correspondant à un meilleur rendement de production de larves chez le Tilapia du Nil Oreochromis niloticus (L.) maintenu en captivité dans les eaux géothermales du sud tunisien. Les résultats ont montré que le Tilapia arrive à la première maturité sexuelle dès la première année d’élevage, à une longueur (Lm50) relativement petite évaluée à 11,3 cm et 12,3cm, respectivement pour les femelles et pour les mâles. La femelle d’O. niloticus présente une fécondité absolue (F) relativement faible (variable entre 241 et 1358 œufs respectivement pour des femelles de 15,5 et de 24,1 cm) et liée à la taille des femelles par la...

Effect of Frequency of Fertilisation on Abundance of Rotifers and Protozoa in Flooded Ponds and Simulation Tanks
Provedor de dados: 20
Autores: Kyewalyanga, M.S.; Mwandya, A.W.
Experiments to assess a suitable rate of fertilisation of earthen ponds for production of rotifers and protozoa were conducted in April 2000. Production of rotifers and protozoa (hereinafter collectively referred to as rotifers) was stimulated by flooding the ponds using seawater and rainfall. In the simulations, seawater diluted to 20 ppt salinity activated initial production. In all systems, the fertiliser concentration was approximately 1 ml of chicken manure to 2 litres of seawater. Three different rates of fertilisation were tested. The results clearly showed that the higher the frequency of addition of manure, the higher the production of rotifers per ml. Fertilised ponds had maximum averages of between 64 and 76 rotifers/ml as compared to a maximum...

Les résultats des données floristiques recueillies, au cours de deux campagnes, dans le secteur oriental de la lagune Ebrié, 1987 (avant la réouverture de l'embouchure)et en 1988 (après la réouverture de l'embouchure) sont présentés dans ce texte. L'augmentation de la salinité (de 4 à 30%) consécutive à la réouverture de l'embouchure du fleuve Comoé, en septembre 1987 a profondément modifié, qualitativement et quantitativement, les groupements végétaux. Les macrophytes flottants libres ou fixés ont été complètement détruits; la forêt de mangrove constituant essentiellement la seule ceinture hydrophytique des berges lagunaires.

The effect of copper on the daily growth rate and photosynthetic efficiency of the brown macroalga Padina boergesenii
Provedor de dados: 20
Autores: Pratap, H.B.; Mamboya, F.A.; Mtolera, M.S.P.; Björk, M.
The effect of copper (Cu) on the daily growth rate (DGR) and photosynthetic efficiency (PE) of the brown macroalga Padina boergesenii was studied under controlled laboratory conditions. The DGR was measured as an increase in fresh weight while the PE was measured as the ratio of variable to maximal chlorophyll fluorescence (Fv/Fm). Padina boegesenii were exposed to 25, 50, 100 and 500mg Cu/l for 21 days. The DGR and PE of P. boergesenii decreased significantly with an increase in copper concentration in the growth media. This study shows that copper is acutely toxic to P. boergesenii at concentrations higher than 500mg Cu/l. Low concentration of copper is toxic to P. boergesenii after a prolonged exposure of 21 days. Similarly, exposure time has a...

It is estimated that approximately 50% of the worlds population live on the coastal fringes of landmasses and the likely trend is for this number to increase to 75% within a decade. For centuries people have been drawn to coastal regions for the rich soils for agriculture (of deltas and lowlands), the extensive fisheries resources, transportation opportunities and recreation, and just for the natural beauty of living on beachfronts. However, the air-sea-land boundary referred to as the coastal zone is dangerous, comprised of an extremely dynamic, complex physical / biological set of environments. Worldwide, the coastal zone is characterized by high population densities, extremely varied and important biological diversity, including coastal fisheries, rich...

Environmental factors other than fishing effort, contribute to influencing marine pelagic fish population dynamics and abundance. There is evidence from environmental modelling and bioeconomic analysis of the Ghanaian marine inshore pelagic fisheries. Ghana is a West African country and lies on the Greenwich Meridian. It is bordered at the South by the Gulf of Guinea. The official language of Ghana is English, but is surrounded by French speaking countries. The inshore fishery is a multi-specie, multi-fleet fishery, consisting of artisanal and inshore purse seine fleets. The coastal inhabitants depend mainly on the marine fisheries as source of employment and livelihood. Fisheries constitute 5% of Agriculture GDP. The two fisheries types in the inshore...

La pêche occupe une place importante dans l’économie et la société sénégalaises. En effet, elle est une activité multifonctionnelle qui contribue à la fois à l’équilibre de la balance des paiements du Sénégal, à la résorption du chômage et à la satisfaction des besoins alimentaires de la population sénégalaise. Malgré son importance, le secteur de la pêche est confronté à de graves déséquilibres socio-économiques et environnementaux qui résultent de la surexploitation des ressources halieutiques et de l’utilisation de certains modes d’exploitation néfastes. Il en découle des difficultés d’approvisionnement des marchés locaux et une diminution de l’apport en protéine des populations tributaires de la pêche. En outre, la forte propension à l’exportation de...

Core D（21°23′02″N，116°47′13″E, water depth 405 m）was sampled from the upper slope from the northeastern South China Sea (SCS) and applied to analyze the sedimentary environmental change in this sea area since the last glacial stage. The results of grain size analysis, diatom analysis and detrital mineral analysis were well matched. We divided the core D into two layers. The surface sand layer (0 - 2 cm) consisted of residual sediments, which might be originally the sediment in the late Pleistocene and later suffered from being transformed in the post glacial transgression.

Characterizing and Comparing the Spawning Habitats of Sardine (Sardinops sagax) and Anchovy (Engraulis encrasicolus) in the Northern Benguela Region
Provedor de dados: 20
Autores: Tjizoo,Mbeurora Beau.
Spawning habitats of sardine and anchovy in eastern boundary current systems are characterized in an attempt to understand the fluctuations observed in their abundance. The northern Benguela, as an eastern boundary current system, is characterized by turbulent conditions that seem to govern the variability observed in the abundance of these species. Sardine and anchovy have developed mechanisms that enable them to maximize productivity. In the northern Benguela, spawning intensity is historically known to be high in periods and vicinities where turbulence is reduced. However, it is believed that selection of conditions for spawning by these species may change withfluctuations in abundance of fish.

Los arrecifes coralinos, uno de los más bellos e importantes ecosistemas de nuestro planeta, han existido por más de 200 millones de años, sobreviviendo a grandes cambios durante su historia (glaciaciones, extinciones masivas, entre otros). Sin embargo, durante las últimas tres décadas se han registrado grandes y súbitos cambios en el medio marino que a juicio de algunos investigadores ponen en peligro la supervivencia de corales y arrecifes coralinos. Uno de los mayores problemas que enfrentan los arrecifes coralinos hoy en día es la aparición de enfermedades que atacan a los corales, la base de estos ecosistemas. No existe un concenso sobre si estas enfermedades son realmente nuevas o no, pero lo que sí se sabe es que algunas de ellas están creando...

The extensive coral reefs along the coastline of Mozambique are a valuable national resource. They provide food and income for a large proportion of the country’s coastal communities and have a great potential for generating substantial economic growth within the tourism sector. The government of Mozambique has recognised the importance of coral reefs and has initiated a number of actions aimed at the sustainable management and conservation of this resource under its National Coral Reef Management Programme (NCRMP). The current two year moratorium on the trade in ornamental fish and live corals is one such initiative and it was important that the opportunity to formulate a framework for the sustainable management of this trade be acted upon quickly. It is...

Autores: Lung'ayia, H.B.O.
Some aspects of the reproductive biology of the Nile tilapia,     Oreochromis niloticus population in the Nyanza Gulf of lake Victoria,     Kenya were investigated from March to August 1991. The overall sex     ratio was 2.08:1 in favour of males. A variation in sex ratio was     observed with females predominating over males in lengths between 37.5     and 41.0 cm total length. Fecundity ranged from 864 to 6316 eggs with     an average of 2141. The relationship between fecundity (F), and total     length (L) and weight (W) was F=22.755 L super(1.2141); F=177.142 W     super(0.342). The fecundity was compared to that reported elsewhere     and together with spawning habits, were suggested as some of that     factors contributing to the abundance of the...

Autores: Santos, B.A.; Renzi, M.A.
Growth of hake (Merluccius hubbsi) in the 0-group from the Argentine-Uruguayan Common Fishing Zone was studied and spawning data were back-calculated by identifying daily growth rings in otoliths of specimens caught during research cruises performed in May 1997, May 1998 and June 1999. Total length (TL) range was 14-69 mm. Increments were read under microscope using an otolith daily ring measurement system (RATOC). Changes in the increment width data present a pattern that seemed to be similar, and independent from birth date of individuals. Data observed and back-calculated showed good accordance with the Laird-Gompertz model. Significant differences between coefficients were found in all comparisons of growth curves for observed and retrocalculated data....

Cayo Largo del Sur, located in the southwest of Cuba south of the Gulf of Batabanó, is a beach and diving resort, far from the main island of Cuba and from Isla de la Juventud. Therefore, it is far from important permanent human settlements and from all agricultural and industrial development. However its western reefs are suffering a gradual deterioration process. Great scarcity of mesoherbivores (sea urchin Diadema antillarum, as well as scarid and acanthurid fishes), and high nutrient concentrations were observed. As a consequence, an excessive algal and cyanobacterial mat proliferation occurred. It has been reinforced by high temperatures in 1998 and by the simplification of bottom relief because of coral mortality caused by diseases and cyclones. The...

Autores: Herdson, D.; Pesantes, J.
153 experimental sets were made with stackable Antillean fish traps in depths of 5 to 30 m in the waters around the Galápagos Island (Ecuador), between Octobre and April 1983. 1,885 fish were caught of 18 species mainly of the families Pomadasyidae, Acanthuridae, Sparidae and Serranidae. The mean catch rate was 5,5 Kg per lift or 0,4 Kg.h-1, and the mean weight of the fish caught was 0,45 Kg. The optimum set duration was found to be between 2 and 18 hours (possibly indicating a high rate of escape). This study took place during the period of the ”El Niño”, when catches of fish in this area generally were low, and it is not known what effect this had. The catches were good compared with other shallow areas, but the fishes caught were mainly of medium...

Introducción al problema de la erosión litoral en Urabá (Sector Arboletes-Turbo) Costa Caribe colombiana
Provedor de dados: 20
Autores: Correa, I.D.; Vernette, G.
Shoreline retreat has been the net dominant historical trend along the 145 km-length littoral between Arboletes and Turbo (Southern Caribbean of Colombia). For the last four decades, there were identified in this littoral shoreline retreats of about 50-100m in several places (Uveros, Damaquiel, Zapata, Turbo) and a maximun of 1.6 km in the Punta Rey-Arboletes area, where land losses were of 4.5 k m2, at exceptional rates of 40m/year. The synthesis of the available information suggest that the general “susceptibility” to erosion between Arboletes and Turbo could be related primarily to relative sea level rise, associated to tectonic movements as well as to the effects of mud diapirism and hydroisostacy. In the more critical areas (Arboletes, Turbo), the...

In tropical estuaries, most fishes feed at different hours during the day. To determine the daily ration and consumption of the Ciénaga Grande de Santa Marta (CGSM) population of Anchovia clupeoides monthly samplings of a 24 h cycle were taken at the coastal lagoon between October 1995 and June 1996. A total of 4389 specimens were examined. The population of A. clupeoides consumes almost twice its weight per year, representing a 0.53% of its body weight per day. Though the CGSM presents a high primary production (990 gC/m2 /year), the percentage that is transferred to the population of A. clupeoides is relatively low (0.055%). Hence, it seems that the high productivity of the CGSM is not being transferred to upper trophic levels due to the kind of...

Tides, tidal currents and their effects on the intertidal ecosystem ofthe southern bay, lnhaca Island, Mozambique
Provedor de dados: 20
Autores: Rydberg, L.; de Boer, W.F.; Saide, V.
Sediment characteristics and tidal currents were studied in the 1500 ha intertidal area south of Inhaca Island, Mozambique. Thetide is semi-diurnal with a range at spring of about 3 m. The area connects directly to the ocean through the Ponta Torres Straitand (indirectly) through several narrow tidal channels ending up in Maputo Bay. Velocities of up to 0.75 m s-1 were measured in the Ponta Tones strait. After Low Water, Indian ocean water starts entering the tidal flats, while entrance from the MaputoBay side is delayed by one to several hours. With only one tide gauge and one current meter at hand, we found indications of ahigher mean sea level on the oceanic side (probably due to ocean wave set up) and a mean flow in the Ponta Torres Straitdirected...

La pêche artisanale en Mauritanie : Résultats des enquêtes cadres de l'année 1989
Provedor de dados: 20
Autores: Diop, H.; Ould Mohamed Vall, M.
Résumé : Au mois de mars 1989, 770 embarcations employant 3537 pêcheurs ont été recensées, tandis qu’au mois d’août de la même année seules 540 embarcations ont été recensées. Ces dernières emploient 2236 pêcheurs, soit une diminution du parc d’embarcation de 30% et de l’effectif des pêcheurs de 38%. Les « Imraguen » commencent à diversifier leur technique de pêche en utilisant de nouveaux engins. La pêche artisanale intéresse de plus en plus les mauritaniens qui n’ont pas une tradition de pêche. En effet, des pêcheurs originaires des régions de l’intérieur de la Mauritanie représentaient 10% de l’effectif en février 1989 et 34% en août 1989. #

Autores: Llanio, M. D.; Fernández, M. D.; Mata, A.; Cabrera, B.; Pérez, M.
At present, there is a worldwide tendency to discover new drugs that provide an answer to treat different illnesses, many of them still without solution and others of difficult treatment. In the last two decades, diverse groups of scientists have concentrated on obtaining natural marine compounds, since they represent a source of new chemical structures. Marine pharmacology has focused its attention on some areas of pharmaceutical development with emphasis on cancer and on inflammatory illnesses. In this work we carry out the study of two extracts from sponges of the Cuban shelf as possible sources of anti-inflammatory and/or analgesic compounds. To achieve this objective the extracts were evaluated in the models of inhibition of phospholipase A2 of bee...

An experimental culture trial of wild juveniles of jewfish Epinephelus itajara was conducted in two different places in the north coast of Colombia in order to evaluate the growth rate of the species and its tolerance to captivity conditions. Two different groups of fish were evaluated in each place, one fed on an artificial diet and the other on trash fish. All fish were held in floating cages for periods ranging from 63 to 89 days. Results showed excellent individual daily weight increase (6,83 and 12,4 g/day) and specific growth rate (1,4 y 0,96 %/day) for fish fed on trash fish in both places but conversion ratio was too high and inadequate (9,01 and 9,97). Trials with the artificial diet gave negative results because the fish didn’t accept the pellets...

Procesamiento y comercialización de la anchoíta (Engraulis anchoita) del Mar Argentino
Provedor de dados: 20
Autores: Bertolotti, M.I.; Manca, E.A.
The anchovy (E.anchoita)is one of the most abundant species in the Argentine Sea. Distributed in between latitudes 34°S and 48°S, it has only been caught, traditionally, along the coasts of Buenos Aires Province - particulary in the vicinity of Mar del Plata. Anchovy-like items are exported both to producing and consuming countries. During the last three years markets have been lost. In order to regain them and to develop new ones, particularly in Europe it shall be necessary to compete with products that are well-priced and of the high quality and have a substantial aggregate value. The anchovy domestic market could be enlarged- with certain limitations- be developing new products.

Autores: Radwan, A.M.; Khalil, M.K.; El-Moselhy, K.M.
Twelve samples were collected from the surface sediments of lagoon and adjacent Mediterranean Sea. Samples were analyzed for grain size, total organic carbon (TOC), total carbonate (CaCO3), various forms of phosphorus and heavy metals (Fe, Mn, Zn, Cu, Ni, Co, Cd and Pb). The results indicated that the sediments were composed of sand, silt and clay enriched with carbonate (1.95 – 34.1%) and total organic carbon (0.06 and 3.62%). The total-P content ranged between 58 and 1186 μg/g, and the fraction associated with apatite minerals (PHCl) was the dominant (it constitutes about 50 – 73% of TP) implying that it was the main storage of phosphate. The various P phases demonstrated significant positive correlation with mean size, silt, clay, TOC, CaCO3 and TP,...

Autores: Gonçalves, P.M.B.; Pereira, M.A.M.
The southern part of Mozambique suffered, at the beginning of the present year, the worst floods in the last 50 years, which caused several fatalities and high material losses. The objective of this study was to investigate the influence of this phenomenon on the coral communities of the Xai-Xai lagoon reef. Benthic category percentage cover was assessed in January 2000 (before the floods) and September 2000 (after the floods) using the line intercept transect (LIT). A decrease of hard coral percentage cover was observed, in the order of 58.5 %. The soft coral community was also affected, with a high decrease of percentage cover, about 90.4%. Other benthic category that showed an elevated decrease was coralline algae (85.1%). All other categories increased...

Influencia ambiental en la distribución espacial de las clases de edad de pez palo (Percophis brasiliensis) en el Sistema Costero del Atlántico Sudoccidental (34°-41° S)
Provedor de dados: 20
Autores: Barretto, A.C.
The age-class distribution of the Brazilian flathead Percophis brasiliensis in relation to environmental variables in spring and winter, and the growth of both sexes, were studied in the SW Atlantic Coastal System (SACS)(34°S-31° S). Growth was studied from 1449 individuals (n=853, spring (1998 + 2000), n=596, winter (2004)) to which size (TL), sex, and age were determined. Age was determined considering that an opaque plus a hyaline band (present in the transverse section of the sagitta otolith) represented 1 year of life. The age-class distribution in spring and winter was established through hierarchical clustering and non-metric multi-dimensional scaling (nMDS analysis). This analysis grouped sampling stations (n=109, spring 1998; n=160, winter 2004)...

Kenya, Reef Status and Ecology
Provedor de dados: 20
Autores: Mdodo, R.; Uku, J.N.; Obura, D.; Wawiye, P.; Mwachireya, S.
Coral reefs along the entire coast of Kenya suffered widespread bleaching and mortality of corals during the first half of 1998 (Wilkinson, 1998; Obura, 1999; McClanahan et al., 1999). This status report summarises findings relating specifically to coral bleaching, mortality and effects on benthic community structure. In addition, preliminary results from a number of research projects investigating different aspects of the bleaching event are reported here. In shallow waters, on a per-area basis, most of Kenya’s southern fringing reefs have lost between 66% and 80% of their live corals. Coral reefs in deeper water suffered less mortality due to lesser exposure to higher temperatures. Reefs on the northern part of the coast, influenced by cold water...

Provedor de dados: 20
Autores: Manrique Rodríguez, N.; Bejarano Chavarro, S.; Garzón Ferreira, J.
As a contribution to the biological knowledge about the sea fan Gorgonia ventalina and the use of this information as a tool to generate conservation and management strategies for this threatened species, a study about its annual growth rate, in different reef areas in Santa Marta and the National Natural Park Tayrona in the Colombian Caribbean took place. Manual measurements of 35 colonies were analyzed and images of 11 colonies were recorded in the beginning and in the end of the field stage. The annual growth rate varies among colonies and areas where measurements were taken. The average annual growth rate obtained with both of the methods was high and oscillated between 7.6 and 8.1 cm/year in height and between 6.9 and 8.3 cm/year wide. The total area...

Se determinó la variación de la talla de los octocorales Eunicea flexuosa y Plexaura kuekenthali en arrecifes coralinos con diferente grado de contaminación urbana en la ciudad de La Habana, Cuba. Se midió la altura de las colonias encontradas a lo largo de un transepto de banda (100 x 1 m). La distribución por tallas de ambas especies mostró una tendencia a que las colonias alcancen una mayor frecuencia relativa en los menores intervalos de tallas en los sitios cercanos a las cuencas fluviales con mayor carga contaminante (medido por el número de fuentes contaminantes y carga dispuesta, DBO). La talla media de E. flexuosa fue significativamente menor en los dos sitios cercanos a las cuencas con mayor carga contaminante. Sus mayores tamaños de efecto...

Autores: El-Sarraf, W.M.
Results of the investigation carried out in Lakes Mariut and Edku revealed that the trace metals concentrations in ceratophyllum demersum is relatively higher than that in Potamogeton pectinatus. The protein and trace metals in macrophytes collected from unpolluted areas is lower thjan that form polluted ones. Eichhornia crassipes can have a restricted role for the treatment of lake water. In Lake Edku, the results of chemical composition of sediments agree with the previous studies. The trace metal content of C. demersum was higher than that of P. pectinatus. The higher organic carbon level was recorded in stems of submerged plants and in leaves of floating ones. On the other hand, the high concentration of trace metal was observed in leaves of submerged...

De nos jours, l’utilisation immodérée et massive des antibiotiques a conduit à l’accroissement du phénomène de l’antibiorésistance pouvant induire la réapparition des épidémies incurables. Dans ce cadre apparait la photocatalyse hétérogène comme une technologie alternative pour dépolluer les eaux contaminées par de telles molécules. Pour cela on a étudié la dégradation photocatalytique de la spiramycine, antibiotique fréquemment utilisé dans la médecine vétérinaire. Nous avons évalué par la suite son activité antibactérienne au cours de sa photocatalyse qui a révélé une perte de toute activité antibactérienne au bout de 45 minutes vis-à-vis Staphylococcus xylosus. Enfin, nous avons testé l’impact de ce processus sur la biomasse bactérienne du même germe...

Evaluación de la tasa fotosintética del alga verde Rhizoclonium riparium (Roth) Kützing ex Harvey, expuesta a cobre y su uso como indicador de contaminación por metales en aguas estuarinas
Provedor de dados: 20
Autores: Montoya, W.; Peña, E.J.; Benítez, R.
Algae have been used as bioindicators by having several advantages such as they have short life cycles, they can take up nutrients directly from water, they are generally easy to collect in sufficient amounts from various habitats; and they readily accumulate compounds present in seawater, making tissue analyses reliable indicators of water quality. In order to evaluate the bioremoval capability of the green alga Rhizoclonium riparium, the photosynthetic responses to heavy metal pollution under different sublethal concentrations of copper was assessed. Photosynthetic rates were significantly low (p &lt;0.05) at low copper concentrations, between (0.01 y 10 mg/l). Maximum photosynthetic values were shown at 30 y 60 mg/l and almost cero at 150 mg/ l of Cu....

This study present the implementation of a Tsunami Forecast System for Galapagos Islands. This system is formed by the development of short and long term forecast models. The first is used in real time, with the information of the occurrence of a tsunami event in the pacific ocean, in order to predict the physical effects of the impact on islands. While, the long term forecast, is used to identify tsunami generation zones with potential threat to damage the islands and also is used to have a reference to evaluate an particular event. The numerical model used to get both forecasts is MOST (Method of Splitting  Tsunamis) with ComMIT methodology (Community Model Interface for Tsunami), wich has been adapted to local conditions.

Some handling practices related to health about finfish culture are analyzed and  discussed in this paper. The wild caught broodstocks were cultivated for two years  under environment conditions in concrete pond where developed techniques  avoided  stressful conditions like high stocking densities which may result in  compromised fish health, disease and mortality. Marine fish species are also  susceptible to many infectious pathogens including parasites. As a result of that,  prophylactic bathes have been identified as method of control. Reproductive  parameters could have showed due to good managements.

Interacciones entre corales y macroalgas: dependencia de las especies involucradas

Autores: Márquez, J.C.; Díaz, J.M.
Macroalgae proliferation on coral reefs has been a recognized phenomenon for the past two decades and is generally entitled to the human activities on the coasts. Even thought, the role of competition in this process is not clear and it has been assumed that algae are competitively superior to corals, even when it has been demonstrated that this is not always the case. It is probable that the result of coral-macroalgae depends upon the species involved. The goal of this study was to demonstrate that there is a dependence relation between interaction category and interacting species. In order to resolve this, quantifications of interactions per category along 20 m transects were done on three representative localities at the Archipielago de San Bernardo....

A study on the seasonal variation of Engraulis anchoita larvae nutritional condition was performed. The material employed was collected at the Estación Permanente de Estudios Ambientales (EPEA) during the 2008-2011 period (Buenos Aires prov., Argentina). In order to determine the morphological differences among individuals, the six morphometric variables measured for each larvae were analyzed using the Principal Component Analysis (PCA). Water temperature and salinity and density of the different ichthyoplankton components were also registered. The PCA revealed a larger larvae body width in Spring, which would indicate an improvement of nutritional condition during that season. Mean abundance of eggs and larvae, higher in spring, was significantly lower...

Se hallaron diferencias significativas fueron encontradas entre los factores de conversión para peso nominal entre áreas y diferentes localidades de una misma área de pesca, lo que puede ser atribuido al desigual comportamiento del peso de la concha. Este estudio propone estimar la captura en base al peso de masa entera procesada a bordo eviscerada. Nuevos factores de conversión son recomendados; 50 % de limpieza a masa...

Spatial-temporal variability of phytoplankton abundance and species composition in Lake Victoria, Kenya: implication for water quality management
Provedor de dados: 20
Autores: Abuodha, J.; Mwirigi, P.; Gikuma-Njuru, P.; Okungu, J.; Hecky, R.E.
Study of phytoplankton abundance and species composition in Lake Victoria, Kenya showed a marked difference between the main lake and the semi-closed Nyanza (Winam) Gulf. Phytoplankton biomass and species composition showed both spatial and seasonal variation. In the main lake the highest chlorophyll concentration was during the short stratification season (August to September) but in the gulf it was after the short and long rainy seasons. Deep mixing depth (aprox. 30 m) in the main lake imposes light limitation to algal growth leading to the observed lower chlorophyll in the main lake, despite the higher soluble reactive phosphorus (SRP) in the main lake compared to the gulf. Blue green algae were the most abundant algal species, contributing between 45...

Bycatch in the purse seine tuna fisheries in the western Indian Ocean.
Provedor de dados: 20
Autores: Romanov, E.V.
The yield of associated and dependent species taken as bycatch by the purse seine tuna fishery from the Indian Ocean pelagic ecosystem is estimated from data collected by scientific observers aboard Soviet purse seiners in the Western Indian Ocean (WIO), 1986-1992. A total of 494 sets on free swimming schools, whale shark associated schools, whale associated schools, and log associated schools were analyzed. More than 40 fish species and other marine animals were registered. Among them only two species, yellowfin and skipjack tunas, are target species. Average levels of non-tuna bycatch equal 0.518 t per set, 27.2 t for 1,000 t of target species. By the author’s estimates, the annual catch of yellowfin and skipjack tunas in 1990-1995 of the total...

1. In the past 20 years, the world has been swamped with reports, action plans and recommendations aimed at curing the ills afflicting our planet. International conferences, environmental campaigns and scientific studies have all advocated precautionary measures and remedies. 2. Humanity must take account of the amount of pressure the Earth can stand, and adopt lifestyles and development methods that respect nature’s limitations, without necessarily having to forgo the benefits of modem technologies. 3. Biosphere reserves are designed to respond to this dilemma. Their effectiveness hinges on synergy between scientists, conservation and development groups, management authorities and local communities. Such requirements are confirmed by the principles of...

Depuis sa parution en Méditerranée nord occidentale en 1984, l’algue verte d’origine tropicale Caulerpa taxifolia n’a pas cessé de progresser le long du littoral septentrional de la Méditerranée. Le présent travail signale pour la première fois la présence de cette algue sur le littoral oriental de la Méditerranée et plus précisément dans la rade de Sousse (Tunisie), en face du port, par 17 mètres de profondeur. L’arrivée de Caulerpa taxifolia à Sousse, n’est certainement pas le résultat d’une progression naturelle à partir d’anciennes station, l’hypothèse la plus probable expliquant son existence dans la rade serait son introduction liée à un transport de boutures par des embarcations ayant auparavant jeté l’encre dans des zones déjà envahies par l’espèce.

Marine Swimming–Related Illness: Implications for Monitoring and Environmental Policy
Provedor de dados: 20
Autores: Allen, P.; Wong, T.; Ford, T.; Epstein, P.R.; Henrickson, S.
There is increasing evidence that environmental degradation may be contributing to an increase in marine-related diseases across a wide range of taxonomic groups. This includes a growing number of reports of both recreational and occupational users of marine waters developing gastrointestinal, respiratory, dermatologic, and ear, nose, and throat infections. The duration and type of exposure, concentration of pathogens, and host immunity determine the risk of infection. Public health authorities may not be able to accurately predict the risk of waterborne disease from marine waters due to the limitations of conventional monitoring, as well as erroneous perceptions of pathogen life span in marine systems. Pathogens undetectable by conventional methods may...

In general, the increased exploitation of the natural organic resources of the world makes it more and more necessary to apply proper resource management procedures in order to avoid overexploitation. In the fisheries field, the managemente is, among other things often based on studies of fish ageing. Such studies have become an important tool, to be used in the elaboration of population dynamic models and of biological parameters like stock recruitment, growth and mortality. In age studies the otoliths and scales of the fish are of basic importance. The reason is that they reflect th occurrence of the biological changes, which take place in the fish during its lifespan. Such changes may derive from for instance the natural growth process of the fish or...

The coastal forest communities of Kenya exist mainly as isolated blocks which show high levels of species endemism and comprise a total of about 83,800ha in a narrow belt which extends inland for about 30km. The forests are characterized by dense or moderately dense stands of tall trees, species of the genera Sterculia, Chlorophora and Memecylon. The drier woodlands include stands of Cynometra, Manilkara and Afzelia. Centuries of human occupation have reduced the forest element which was originally more extensive. Mangrove swamps occur in tidal estuaries and lagoons while coconut palms are common above high tide. A complex of many bush types occur in the high bush area. Scattered baobab trees present a striking appearance while the prevalence of mango...

A study was conducted between July 2002 and June 2003 to assess the role of salinity, temperature, pH and dissolved oxygen on the abundance of planktonic (phyto- and zooplankton) and phytobenthic (algal mats) communities in shallow (40 cm depth) earthen ponds at Makoba, Zanzibar. Among the zooplankton, rotifer abundance peaked during the rainy period (salinity of 27–42‰) while protozoa and copepods were most abundant during the dry period (max salinity of 70‰). However, no season effects were seen on the phytobenthos. The most abundant genera were Pseudonitzschia sp., Schizothrix sp., Microcoleus sp. and Oscillatoria sp. and in general, algal mats were available throughout the year. Other variables such as temperature, pH and oxygen concentration did not...

Essai et mise au point d'un chalut de fond à grande ouverture verticale (gov)
Provedor de dados: 20
Autores: Bdioui, M.; M’rabet, R.; Ben Naceur, L.
The main object of this study is to develop a big vertical opening bottom trawl (GOV) adapted to the Tunisian fisheries. Two models of trawls were tested. One for a trawler with 600 horse power engine and another model for a trawler with 900 horse power engine. The obtained results in this study show that the two models of trawls tested are efficient, especially in the areas where we found benthic and pelagic species together. Further more, the yield of these trawls is higher than that of the shrimp’s trawl, the most gear used in Tunisian water.

Catch status of tropical tunas and swordfish by Taiwan deep sea tuna fishery in the Indian ocean in 1999.
Provedor de dados: 20
Autores: Chang, S.K.; Liu, H.C.
There were about 341 deep-sea longliners operating in the Indian Ocean (small longliners operating in the northeast Indian Ocean were not included) in 1999, about the same level to 1998. The total catch made by these longliners was roughly estimated as 99,000 MT, a decrease of about 11,000 MT from 1998. The drop of yellowfin tuna by 5,700 MT was the main cause, followed by decreases of bigeye tuna by 2,600 MT and swordfish by 2,100 MT. This decrease in catch might be due to the unfavorable fishing condition around the traditional fishing grounds in the Indian Ocean. In general, the total catch of tunas and billfishes was around 93,000-110,000 MT from 1992 to the present except the relatively high catch in 1993. 'Research Group' Overseas Fisheries...

Autores: Bertolotti, M.I.; Hernandez, D.R.; Pagani, A.N.; Castañeda, M.F.
In order to better understand the behaviour of the trawler processing freezer fleet in the Argentine Sea, an analysis of yields and structural characteristics for the 1989-98 period was carried out. The relationship between structural variables and yield expressed in kilos per day was explained with a simplified asymptotic model. The fleet was divided into four homogeneous strata. Common hake is the target of stratum I and stratum II which are deeply affected by overfishing of the species. As of 1993, in stratum III, common hake was replaced by other pelagic and demersal species, mainly hoki. In fleet stratum IV southern blue whiting and hoki were caught. Catches of the latter increased during the last three years.

Benthic communities and geomorphology of the Tesoro Island Coral Reef, Colombian Caribbean
Provedor de dados: 20
Autores: Sánchez-M., Juan M.
The benthic communities distribution in Tesoro Island (Colombian Caribbean) coral reef was determinad by cartography of reef morphology and functional groups from aerial photographs, theodolite triangulation, and bottom transects over depths ranging from O to 30 m. Tesoro Island is a sand cay reef developed over an emerged reef platform whose basal cone possibly originated by mud diapirism on the continental shelf. The benthic communities are distributed as subzones of the geomorphologic units. The reef crest lies along the breaker zone, formed by Millepora spp. buttresses covered on their tops by Palythoa spp. and seawardly by a turf of Dictyota spp. The rear reef (varying from 0.5-1.5 m ¡n depth) is composed of pavement and grooves with live Porites...

"El Niño" 1982-83 respondió a un patrón de formación diferente a aquel que había sido característico para los fenómenos anteriores, a tal punto que sobrevino en forma sorpresiva y como una consecuencia de las fluctuaciones climáticas relacionadas con la oscilación Sur. Su desarrollo se inició en Junio de 1982 y no llegó a la costa ecuatoriana sino hasta Octubre, aunque en agosto ya se sentían sus primeras manifestaciones como la tendencia del Frente Ecuatorial a desplazarse hacia el sur y la profundización de las isotermas y la termoclina. En Noviembre el fenómeno estaba en pleno desarrollo en las aguas nacionales y en enero llegaba a la máxima intensidad, para posteriormente notarse un ascenso paulatino de las isotermas y termoclina, aunque las...

Mida Creek (Kenya) comprises mangrove forests and other marine resources that are of economic, ecological and environmental importance to the local village communities.  In total 116 households (100 of which could be used for numerical analysis), which are estimated to correspond to a coverage of ca. 30 % of the total Mida Creek population, were interviewed to assess the human reliance on mangrove resources in Mida Creek.  The survey indicates that mangroves are a major resource of wood for house construction, fuelwood, charcoal and boat building.  Minor uses of mangrove products include pharmaceutical and medicinal applications, tanning material and furniture making.  Rhizophora mucronata, Ceriops tagal and Bruguiera gymnorrhiza are the major resources...

Modelación de escenarios de corrientes marinas en presencia de frentes fríos y su relación con la deriva de organismos en Playas del Este
Provedor de dados: 20
Autores: Arriaza, L.; Rodas, L.; Lugioyo, M.; Loza, S.
Durante la incidencia de los frentes fríos de cualquier intensidad en toda la Ensenada de Sibarimar, el movimiento neto del agua sigue el contorno del litoral costero E-W. La circulación marina, además, mantiene fluctuaciones en la dirección perpendicular a la del movimiento medio. Las velocidades máximas de la corriente son altas entre 100-200 cm/s. En condiciones de régimen habitual, la traslación más rápida de los organismos, en dirección paralela a la costa, ocurre desde Guardafronteras hasta Calle 476-478, recorriendo 7 m en 2 min. Durante la acción de frentes fríos, ya sean débiles, moderados o intensos toda la costa será afectada por la deriva, ocurriendo la mayor recala de organismos hacia el W de la Ensenada de Sibarimar.

The coastal areas of Kenya are known to be rich and extremely valuable as they concentrate a rich diversity of natural habitats and a large variety of natural resources. Coastal communities have from time immemorial depended on the exploitation of these resources for commerce and industry. Alongs this coastline, mangroves are common feature in delta, creeks, protected bays, island and river estuaries.

Marine Plants of Tanzania. A field guide to the seaweeds and seagrasses of Tanzania.
Provedor de dados: 20
Autores: Oliveira, E.C.; Österlund, K.; Mtolera, M.S.P.
This is a book about the macroscopic marine plants of Tanzania, namely the seaweeds or benthic macroscopic algae and the seagrasses, that are marine flowering plants. Having flourished in the 19th century and the beginning of the 20th century, taxonomic studies then became less popular and the emphasis of biological investigations turned to other aspects of biology. However, after realising how important the conservation of biodiversity is, we are now experiencing a new interest in a more naturalistic approach to biology. But today this “romantic” approach is often fuelled by extensive bioprospection, the search of new drugs and gene conservation for use in transgenic organisms of commercial value. This in itself could justify the production of a new book...

Autores: Erfa, A.v.; Geister, J.
En el mes de nov./1969 olas larga procedentes de un huracán en el NW del Mar Caribe causaron temporalmente la erosión de la "Punta la Loma", una punta de arena situada en la playa frente al aeropuerto Simón Bolívar de Santa Marta. Como resultado de este suceso afloró el sustrato de esta punta, el cual esta formado de una granodiorita encrustada por corales arrecifales y cubierta por una arena cementada. En la fauna coralina están presentadas solamente especies recientes conocidas de la costa colombiana del Caribe. También se encontraron algunos moluscos y abundantes restos litificados de raíces de mangles.

Coral Reefs: Their Functions, Threats and Economic Value
Provedor de dados: 20
Autores: Cesar, H.S.J.
Coral reef ecosystems provide many functions, services and goods to coastal populations, especially in the developing world. A variety of anthropogenic practices threatens reef health and therefore jeopardises the benefits flowing from these services and goods. These threats range from local pollution, sedimentation, destructive fishing practices and coral mining to global issues like coral bleaching. Economic valuation can help to shed light to the importance of the services and goods by ‘getting some of the numbers on the table’. Valuation techniques are discussed and a summary of economic studies on coral reefs is presented. The concepts of Total Economic Value and Cost Benefit Analysis are used to illustrate the valuation of marine protected areas...

Una metodología alternativa para la evaluación de la biomasa desovante en peces pelágicos como la anchoveta, corresponde al Método de Producción de Huevos (MPH), desarrollada en 1980 por investigadores del Southwest Fisheries Sciences Center, La Jolla, California. La producción diaria de huevos se estima a partir del número de huevos totales evaluados en una prospección ictioplanctónica, en asociación a otras variables, y la fecundidad específica diaria de la población adulta se determina mediante el procesamiento de muestras de peces, obtenidas durante cruceros de pesca, las que proporcionan información respecto de la fecundidad parcial, peso promedio de hembras, frecuencia del desove y proporción de sexos.

Diagnostic des pêcheries du poulpe (Octopus vulgaris)  dans les eaux sous juridiction sénégalaise: Rapport définitif
Provedor de dados: 20
Les seiches, poulpes, calmars et nautiles forment la Classe des Céphalopodes de l’Embranchement des  Mollusques de grande taille, exclusivement marins. Leur croissance est rapide, leur arrivée à la maturité sexuelle précoce et leur durée de vie courte. Le poulpe a une très large aire de distribution incluant les eaux maritimes tropicales. Elle abonde surtout en Méditerranée, dans les eaux japonaises (Océan Pacifique) et dans l’Atlantique Centre-Est qui  s’étend du Maroc à l’Angola.   La pêche du poulpe s’est développée au large du Sahara dans les années 1960. Son importance dans la zone du COPACE notamment, au Maroc, en Mauritanie et au Sénégal, s’expliquerait par la raréfaction de ses prédateurs potentiels (Serranidés, Sparidés).  Au  Sénégal, elle est...

A description of Illex argentinus beaks, made on the basis of qualitative and quantitative characteristics, is presented. Likewise the equations that represent the relationships between the rostral length of each beak with the mantle length and total weight of squids are proposed, as a tool for reconstructing them. A total of 291 squids, comprising the complete size range, from juveniles to adults,were analyzed for the latter purpose. The morphometric description was made on a total of 90 individuals from the Argentine Sea, taking the following measurements on each beak: rostral length, hood length,crest length, wing length and wing width. Results showed that Illex argentinus beaks present the general scheme of that corresponding to the Ommastrephidae...

Obervations on the commercial light fishing operation in Ghana
Provedor de dados: 20
Autores: Quartey, R.; Bannerman, P.
Light fishing operations (LFO) in Ghana is concentrated in the three major coastal municipalities of Greater Accra (Tema), Central (Mumford &amp; Elmina) and Western (Sekondi) Regions; these areas have the port facilities for landing of the catch by the larger inshore vessels that operate the purse seine fishery in Ghana and which predominantly operate the light attraction. Currently there are about 250 registered inshore vessels in the country whose sizes range between 39 – 60 feet , only a small fraction are actually working at the moment due to problems with spare parts and operations. Light attraction is the technique of aggregating fish by artificial light; and light fishing is the process of fishing the attracted fish by hooking, gill-netting or by...

Los invertebrados y las plantas marinas han provisto una nueva fuente de sustancias farmacológicas para el estudio de mecanismos que median los procesos inflamatorios (Jacobs et al., 1993). Se han descubierto nuevas clases estructurales de compuestos antiinflamatorios en la evaluación farmacológica de productos naturales marinos puros aislados de esponjas, gorgonias, corales y algas (Glaser et al., 1989). Debido a que en las costas cubanas hay abundancia de especies marinas, particularmente esponjas y celenterados aún poco estudiados, decidimos explorar los posibles efectos antiinflamatorios-analgésicos de cinco extractos provenientes de esponjas y gorgonias de nuestro archipiélago.

The main purpose of this paper is to describe the seasonal distribution and length structure of the Pink cuskeel Genypterus blacodes. Data from surveys carried out between 1973-1989 were used. Basic data included Pink cuskeel densities per haul, catch length structure, depth and haul position. Pink cuskeel distribution was obtained by using the same density ranges for all seasons. A cluster analysis was applied to group the individual length structure of each survey catch. All year long the principal concentrations were within 40° and 48°S. Throughout the year the adults and juveniles were present in San Jorge Gulf, Patagonia, Argentina, so bimodal distribution were obtained. In winter juveniles were located within the sector 37° and 41°S. During autumn,...

Thermochemistry of strontium incorporation in aragonite from atomistic simulations
Provedor de dados: 20
Autores: Grau-Crespo, R.; Ruiz-Hernández, S. E.; Ruiz-Salvador, A. R.; De Leeuw, N. H.
We have investigated the thermodynamics of mixing between aragonite (orthorhombic CaCO3) and strontianite (SrCO3). In agreement with experiment, our simulations predict that there is a miscibility gap between the two solids at ambient conditions. All SrxCa1 xCO3 solids with compositions 0.12 &lt; x &lt; 0.87 are metastable with respect to separation into a Ca-rich and a Sr-rich phase. The concentration of Sr in coral aragonites (x   0.01) lies in the miscibility region of the phase diagram, and therefore formation of separated Sr-rich phases in coral aragonites is not thermodynamically favorable. The miscibility gap disappears at around 380 K. The enthalpy of mixing, which is positive and nearly symmetric with respect to x = 0.5, is the dominant...

On the basis of observations, it is recommended that 127 mm should be     the minimum mesh size of gillnet permitted on Lakes Victoria and     Kyoga. The minimum length of Nile tilapia (Oreochromis niloticus)     should remain at 28 cm but that of Nile perch (Lates niloticus) should     be increased from 46 cm to 50 cm. The minimum mesh size limit of seine     net for Mukene on Lake Victoria should be 10 mm and fishing for Mukene     should be done using lampara net operated offshore.

Autores: Angulo-Valdés, J.A.; Hatcher, B.G.
La efectividad de manejo se entiende como el grado en que los objetivos de manejo de un área protegida han sido cumplidos.  Antes del 1993 no existían en la literatura trabajos sobre este tema, y solo se encontraban artículos que trataban sobre los  objetivos y beneficios de las áreas protegidas vistos desde una perspectiva biológica solamente. En el presente trabajo se  desarrolla una nueva metodología para evaluar la efectividad de manejo de un área marina protegida y la misma se aplica a  un estudio de caso real. La metodología propuesta constituye una herramienta interdisciplinaria que pudiera mejorar el  manejo de las áreas marinas protegidas. Esta metodología constituye un paso adelante que se nutre de las contribuciones  anteriores y provee un nuevo...

Feasible Rate of Tidal Flat Reclamation:Jiangsu Mud Coast as a Case Study.
Provedor de dados: 20
Autores: Wang, Yanhong; Li, Jialin; Wang, Jian; Zhang, Renshun.
Reclamation of tidal flat is one of the main ways to get a dynamic balance of the total amount of plowland. With the development of social economy and the increasing demand for plowland, the contradiction between tidal flat reclamation and environment protection becomes more and more outstanding. However，tidal flat reclamation should also follow the dynamic balance of total amount of tidal flat amount. The paper analyzed the history of reclamation and development of Jiangsu mud coast, and calculated the feasible rates of tidal flat reclamation on different stretches respectively, and pointed out that both the economic social benefits of reclamation and the natural erosion-accretion conditions of the coasts should be taken into consideration in deciding the...

Autores: Zarrad, R.; Gharbi, H.; Missaoui, H.
The production models of Schaefer and Fox are used to determine the optimal effort of benthic trawlers in Tunis Gulf. The necessary data for the application of these models were collected from services of General Direction of Fishing and Aquaculture (DGPA). They are related to the two fisheries which exploit the benthic resources : trawling and coastal fishing and are extended over 12 years (from 1988 to 1999). The unit of effort selected, which gives the best correlation coefficient is the number at days at sea times : The day number at sea time the engine power of the fleet. In the current exploitation state, the optimal effort is estimated at 15 benthic trawlers with an average power of 450 cv.

The implementation of the GPA is primarily the task of Governments, in close cooperation with all stakeholders including local communities, public organizations and the private sector. The GPA identifies the Regional Seas Programme of UNEP as an appropriate framework for delivery of the GPA at the regional level. The Regional Seas Programme was initiated by UNEP in 1974 as a global programme implemented through regional components. Since then, the Governing Council of UNEP has repeatedly endorsed a regional approach to the control of marine pollution and the management of marine and coastal resources and has requested the development of regional actions plans.

Stichopus chloronotus is a holothurian of the orderAspidochirotes, family Stichopodidae, that is widelydistributed across the tropical Indo-Pacific region. It ismainly found on reef flats and slopes with considerablehydrodynamic energy. The species' density is relativelylow, but sometimes reaches up to several specimens perm2 (Franklin 1980; Conand 1989; Uthicke 1994; Conandet al. 1998).   Similarly to nine other Aspidochirotes sea cucumbers,they can reproduce both sexually and asexually (Uthicke1994, 1997,2001; Conand et al. 1998). Their sexualreproduction has been studied in Australia (Franklin1980) and Malaysia (Tan ShauHwai and Bin Yasin 2000).Asexual reproduction is achieved by transverse fissionresulting in two animals that each regenerate the...

Study on desalination by a flowing liquid membrane
Provedor de dados: 20
Autores: Naim, M.M.; Monir, A.A.
Desalination is characterized by rapidly evolving technologies. These technologies are divided mainly into thermal and membrane processes. Thermal processes, however, have numerous limitations, which include intensive use of energy and corrosion problems while membrane processes suffer from membrane fouling and high membrane cost and other problems. Liquid membrane (LMs), on the other hand, which have been discovered in 1968 by Li have no pores to be blocked and cannot be fouled like solid membranes. They also exhibit higher permeabilities and higher selectivities than solid membranes. However, their main problem is the method of containing the liquid between the two miscible but separated donor phase (DP) and receptor phase (RP). LM techniques include...

Provedor de dados: 20
Autores: Betanzos Vega, A.; Arencibia Carballo, G.
Production of mangrove oyster (Crassostrea rhizophorae Guilding, 1828), north of Villa Clara, Cuba Province, tends to decline since 1980, accentuating from 2003 on. Despite regulations to protect the resource, minimum legal size and catch closures, the year 2008 presents the landing smaller volumes of the past 50 years. An analysis of the variability of catches in relation to natural and human factors, allows for precipitating causes of low productivity of this fishery resource; between the most representatives are expanding storage capacity of river water, salinity increment, the increase in frequency and intensity of hurricanes and the mismanagement of the extraction of oyster.

The mothership/dory fishing operation 'Pecheur Breton' spent 13 days fishing at the northwestern submarine promontory of Saya de Malha Bank between 24th February and 14th March 1993.  The mothership fished using 12 dories which were equipped with echo-sounders and electric fishing reels.  A total of 74.3 tonnes of fish was caught in the depth range of 55 to 130 m. of  which the blue spotted jobfish (Pristipomoides filamentosus) represented 80%.  The catch rates were observed to decreased with time and could not be attributed to changes in climatic conditions, fishing depth, fishing method or bait type.  The initial biomass of Pristipomoides filamentosus at the northwestern submarine promontory of Saya de Malha Bank was estimated at 76.1 tonnes through...

This paper reviews the state of the environment in Ghana and explores the potential for the use of institutional, legal and economic instruments in environmental management in the specific context of this developing country. The environmental situation in Ghana is characterised by desertification, land degradation, deforestation, soil erosion, desertification and inadequate water supply in the Northern regions of the country. The population as a whole is growing at a rate of 3% per annum, with even greater urban growth rates, due to rural out-migration. Large parts of the coastal zone in the south are rapidly developing to become one large suburbanised area. Water quality is particularly threatened in the urban and industrialised areas, which are mainly...

Cambios históricos en la distribución y abundancia de praderas de pastos marinos en la Bahía de Cartagena y áreas aledañas (Colombia)
Provedor de dados: 20
Autores: Díaz-M., J.M.; Gómez-López, D.I.
The spatial distribution of seagrass beds within the Cartagena Bay and neighboring areas was reconstructed through comparative analyses of maps, aerial photographs and satellite imagery, as well as observations in the field for five time periods within the last six decades. From slightly more than 1,000 hectares of seagrass beds existing in 1935-45, only 76 remained in 2001, which is less than 8%. The loss rate of seagrass within the bay showed an inverse exponential pattern, whereas outside of the bay the tendency was linear. The almost disappearance of this community was probably raged by the reopening of the Canal del Dique early in the thirties, causing the introduction of important amounts of turbid freshwater and sediments into the bay, and...

Provedor de dados: 20
Autores: Torres Pablos, D.
Las inundaciones por penetraciones del mar en la costa Norte de la región occidental de Cuba, son producidas por áreas formadoras de oleaje asociados a fenómenos meteorológicos peligrosos que transitan por el Golfo de México como bajas extratropicales, frentes fríos y huracanes. Dada una situación meteorológica peligrosa para esta área, se quiere predecir si se producirán o no inundaciones costeras por penetraciones del mar, a partir del análisis de los datos de los fenómenos meteorológicos anteriores, teniendo en cuenta el conjunto de valores de presión para la rejilla que abarca el Golfo de México. En la presente investigación se aplicó el modelo de Redes Neuronales Artificiales con aprendizaje supervisado: Perceptrón Multicapa, el cual establece una...

Seychelles, Initial National Communication. Under the United Nations Framework Convention on Climate Change
Provedor de dados: 20
The Republic of Seychelles acceded to the United Nations Framework Convention on Climate Change (UNFCCC) on the 22nd September 1992, being the second country to do so. Likewise, the Seychelles was one of the earliest countries to sign the Kyoto Protocol on the 20th March 1998. The Initial National Communication to the UNFCCC by the Seychelles reflects our continued commitment to the process. Although the guidelines provided for the preparation of initial national communications by non-Annex I Parties do not place much emphasis on issues of vulnerability, adaptation and capacity building, my country is convinced that without sufficient attention given to these issues many small island states will not be able to cope with the impacts of climate change.

Plan de acción nacional para reducir la captura incidental de aves marinas en las pesquerías uruguayas
Provedor de dados: 20
Autores: Domingo, A.; Jiménez, S.; Passadore, C.
La captura incidental en pesquerías comerciales ha sido identificada como una de las principales amenazas para la conservación de este grupo de aves, siendo los albatros (familia: Diomedeidae) y los petreles (familia: Procellariidae) las especies más afectadas. Debido a que los albatros y petreles presentan una gran longevidad y una baja fecundidad, pocas crías y un lento desarrollo, sus poblaciones son muy sensibles al aumento en la tasa de mortalidad causado por la captura incidental en las pesquerías. Anualmente son capturadas y muertas miles de aves marinas en las pesquerías comerciales que operan con diferentes configuraciones de palangre alrededor del mundo. Este arte, entre otras causas, está contribuyendo al descenso de varias poblaciones de...

Private Sector Management of Marine Protected Areas: The Chumbe Island Case
Provedor de dados: 20
Autores: Riedmiller, S.
The number of privately managed Marine Protected Areas (MPAs) is small but increasing. Chumbe Island Coral Park (CHICOP), established in 1991 and possibly the first fully functioning MPA in Tanzania, provides an interesting illustration of issues that arise with the instalment of a privately created and managed protected area. Challenges caused by the legal and institutional environment for private investment in conservation resulted in much higher costs than originally anticipated. The history of CHICOP, management experiences, problems and achievements in the legal and institutional environment of Zanzibar, Tanzania are described and lessons learned are summarised. Management costs of the privately established and managed park are only a fraction of what...

Multigear fishery of Nile perch (Lates niloticus) in the Winam Gulf of Lake Victoria: with special reference to mortality, selection and catch/effort data
Provedor de dados: 20
Autores: Manyala, J.O.; Rabuor, C.O.
A survey of multigear fishery of Nile perch (Lates niloticus) in the     Winam Gulf of Lake Victoria indicates that total mortality coefficient     (Z) determined from longline fishery using hook number 6 was double     that of hook number 7. Total mortality coefficient determined from     gillnets and beachseines were lower than those of hooks. The catch per     unit effort (C/f) measured using different criteria indicated an     increase for all gears in 1990 as compared to 1989 except for     gillnets. A two-fold increase in unit effort (f) increased the C/f for     mosquito seines by only 30%. The typical exponential decay of C/f with     increasing f of exploited stock in equilibrium was lacking in the case     of Nile perch in the Winam Gulf.

Experiencias de selectividad en los copos de las redes de arrastre y desarrollo en dispositivos selectivos con grillas en la pesquería Argentina.
Provedor de dados: 20
Autores: Ercoli, R.; Izzo, A.; Salvini, L.; Garcia, J.C.; Bartozzetti, J.D.; Roth, R.R.
Major results and difficulties which resulted from experiences in species and per size selectivity for the Argentine fishery are described. Codend selectivity and grid sorting devices trials were carried out. The use of grids not only reduced by-catch of hake in the shrimp fishery but also improved juveniles selectivity in the hake fishery as compared to mesh selectivity. No changes in fishing gears or in fishing manoeuvres were necessary. It was concluded that, to achieve a better rational exploitation of fishing resources, it is necessary to enhance selectivity of fishing gears. Deeper knowledge and further training of crews on Argentine fleets is also encouraged.

Comparative study on growth of chub mackerel (Scomber japonicus Houttuyn, 1782) from three different regions: NW Mediterranean, NE and SW Atlantic
Provedor de dados: 20
Autores: Perrotta, R.G.; Carvalho, N.; Isidro, E.
The von Bertalanffy growth parameters for chub mackerel (Scomber japonicus) from the NW Mediterranean, along the Catalan coast (Spain), were estimated. These results constitute the first estimated values for chub mackerel in this area and were as follows: L∞(cm) = 39.75; K (years-1) = 0.298; t0 (years) = -1.40 (for age groups 0 to 8). These results were compared with the estimated growth parameters for the chub mackerel that inhabits other two regions: NE Atlantic (Azores) and SW Atlantic (Argentina). Significant differences in growth curves between regions were found when the growth parameters, L∞, K and t0, were simultaneously compared. When comparing the growth parameters L~! and K individually, significant differences between regions were also...

La pesca es una de las actividades humanas más antiguas. Los registros de su práctica se remontan a varios miles de años. Los productos que de ella se obtienen juegan un importante papel en la dieta humana como fuente de proteína animal, minerales y ácidos grasos esenciales, entre otros. La inmensidad del océano y su biodiversidad, dio lugar por mucho tiempo a la creencia de que el mar era una fuente ilimitada de recursos, capaz de sustentar la población humana indefinidamente. Nada parecía alertar sobre la necesidad de usar métodos de pesca racionales, ni sobre las serias consecuencias ambientales que puede conllevar la actividad pesquera. El perfeccionamiento de buques pesqueros y de las técnicas de navegación determinó un explosivo crecimiento de la...

Provedor de dados: 20
Autores: Gong, Jianming; Chen, Jianwen; Liang, Jie; Zhang, Zhixun; Liu, Chuang; Lu, Zhenquan; Huang, Fulin.
Using satellite remote sensing to measure the sea surface temperature of the East China Sea Shelf Basin can serve the purpose of predicting the petroleum prospect in the South Yellow Sea Basin. The satellite thermal infrared temperature anomaly area always repeats in the same position as the proved oil prospect area in the East China Sea Shelf Basin, and coincides well with both the CH4 content curve at the water-atmosphere interface and the seafloor geochemical anomaly. The sea surface temperature anomaly areas of the South Yellow Sea Basin in the satellite remote sensing image go banded along 123?30? in the S-N direction, and naturally follow the aeromagnetically interpreted eastern nose-type uplift that shows a S-N strike. The north and south ends of...

Evaluation de la biomasse piscicole dans les plans d'eau douce tunisiens : approches analytique et acoustique
Provedor de dados: 20
Autores: Djemali, I.
La pêche dans les eaux douces est une activité relativement récente en Tunisie. Elle n’a connu un essor important que dans les années 90 à la suite du projet de coopération Tuniso-allemand de la Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ). Les retenues de barrages tunisiens constituent des macrocosmes dont l’équilibre halieutique peut être perturbé par l’introduction de nouvelles espèces ou par l’activité anthropique notamment la pêche.  L’objectif de ce travail est de quantifier les biomasses spécifiques exploitées dans les plans d’eaux douces tunisiens afin de donner leurs états d’exploitation. Pour ce faire, deux méthodes ont été utilisées : la modélisation analytique et l’hydro¬acoustique.  La modélisation analytique et plus...

Analysis of the Purse Seine Fishery of Mauritius, 1990 - 1994, and Comparison of Catch Rate and Species Composition of Catches of Mauritian Purse Seiners to Those of the French Fleet
Provedor de dados: 20
Autores: Norungee, D.; Lim Shung, C.
The catches made by purse seiners on schools associated with logs constitute more than half of the total catch of the purse-seine fishery of the western Indian Ocean. In the purse-seine fishery on log-associated schools of tuna, either natural logs are spotted by vessels and are marked with radio beacons, or artificial logs are set at sea to concentrate the tuna prior to fishing operations. The first attempt at commercial purse seining was successfully carried out in the Indian Ocean in 1979 by a joint-venture Mauritian vessel using the same technique as the Japanese, who had traditionally fished on schools associated with logs in the Pacific Ocean. They started fishing in the Indian Ocean after experimental purse-seine fishing was conducted by the Japan...

Provedor de dados: 20
Autores: Alvarez, J.S.; Hernandez-Llamas, A.; Galindo, J.; Fraga, I.; Garcia, T.; Villareal, H.
The feasibility of substituting soybean meal for ¢shmeal diets for juvenile white shrimp Litopenaeus schmitti (0.35   0.01g) was evaluated, and an adequate substitution level was determined. Five diets were evaluated using 46%, 59%, 75%, 88% and 100% substitution levels. Pellet water stability was signi¢cantly a¡ected by dietary soybean content (Po0.05). Increased soybean content produced lower pellet stability, ranging from a dry matter loss of 14^ 22% after a 2-h immersion, and 20^33% after an 8-h immersion. After 52 days, signi¢cant di¡erences (Po0.05) were found in shrimp weight, feed conversion ratio and protein e⁄ciency ratio. The values were 0.64^1.06 g, 2.8^7.9 and 0.45^1.21, respectively, for the three measurements. Overall, better results were...

Private sector investment in Marine Protected Areas-Experiences of the Chumbe Island Coral Park in Zanzibar/Tanzania

Autores: Riedmiller, S.
Chumbe Island Coral Park (CHICOP) illustrates issues that arise with the establishment of a private marine protected area. Though the legal and institutional environment for private investment in conservation in Zanzibar/Tanzania required much higher investment than originally anticipated, establishment and management of the park cost only a fraction of what is commonly budgeted for donorfunded projects through government agencies. Out of necessity, cost control and income-generating activities of private operations are more developed, thus creating better prospects for sustainability. Training local fishermen as park rangers by volunteers proved to be particularly cost effective and crucial to the success of the MPA and facilitates direct partnership with...

Panulirus argus postlarva performance fed with fresh squid
Provedor de dados: 20
Autores: Rodríguez-Viera, L.; Perera, E.
There is a great interest in the growout of spiny lobster postlarva captured in the wild. This activity has been developed  rapidly in Asia and especially in Vietnam. However, lack of appropriated formulated diets remains the main constrain to the  sustainable expansion of this activity worldwide. Until now,  best growth rates have been obtained with the use of high  inclusion of krill meal and/or krill hydrolysates which are expensive. However, squid is today avoided as food ingredient due  to low digestibility reported. Also, fresh squid has been demonstrated to produce poor growth performance in temperate  lobsters, but there is no report for P. argus fed exclusive on fresh squid. This work examines the effect of fresh squid on  growth of P. argus...

The Réunion fishery has experienced rapid growth and development in all segments (artisan fishery, Antarctic deep sea fishery, longline fishery) for the last five years, in marked contrast to the situation experienced by the huge majority of other European Union fishing communities. The longlining sector, which began five years ago, has shown the most rapid of development. Longlining has, since 1996, not only equalled but overtaken the artisan fishery, with more than 2,300 t production in 1997 and an active fleet of 21 vessels which range from 9 to 33 m long. This fishery targets swordfish (Xiphias gladius) mainly throughout the year, from the equator to 32oS, using deep freeze conservation techniques. The artisanal segment has also shown a rapid extension...

Autores: Abdel-Aziz, N.E.
Diel vertical migration of different zooplankton groups in Dekhaila Harbor was studied monthly from May 2003 to April 2004. Generally, more groups were found in the surface layer (0-10 m.) than the deeper one (10-20 m.). Some zooplankton groups undergo significant vertical migration at certain time of the year, others showed no clear differences in distribution patterns and exhibited no directed movement patterns. Some species stayed a part of the day within certain layer of the water column, others were randomly dispersed in the whole water column during different hours. Responses appear to depend also on the life stages of each zooplankton group, as well as other ecological conditions such as temperature, light and amount of food. Population budget...

More than one hundred oceanographic stations were occupied between the Galápagos Archipiélago and the Ecuadorian coast during April-May 1995. All the information were treated statically using the method of ”Kriging” to interpolate; from this, surface distribution of sea temperature, sea temperature anomalies, air temperature, and atmospheric presion were obtained. These distributions with temperature and salinity profiles showed the end of the warm period 1994-1995. Upwelling events were detected and were supposed to about 24% of AESS. From the mass water analysis carried out to the east San Cristóbal. It was found a probable relationship between the AESS and the ASTS, and the pelagic fisheries.

The reported landings for the whole coastline off Morocco have been assembled from FAO statistics, Moroccan and Spanish Ministries records, and FAO working group reports. The resulting estimate of reported landings is close to the published statistics from FAO for the years 1975-1997. For the period 1950-1974, the landings obtained are considered to be under-estimates as the reporting structure was not fully in place. Because the Spanish fisheries have been historically important on the coast of Morocco, a more complete description of their catch statistics have been included. In addition, discard rates and unreported landings have been estimated based on several studies in the region.

Sesgos asociados a censos visuales de peces arrecifales en el Pacífico Oriental Tropical: implicaciones del uso de transectos sencillos de tamaño mixto, de la experiencia de los buzos y de la estimación de la talla
Provedor de dados: 20
Autores: Palacios, María del Mar; Zapata, Fernando A.
Los censos visuales en transectos de banda implementados para evaluar las poblaciones de peces arrecifales en el Pacífico Oriental Tropical (POT) varían mucho en el tamaño de las unidades de muestreo y en los protocolos de censo. Para examinar los efectos de tal variación sobre los estimativos de riqueza y densidad de especies, y contribuir a identificar un protocolo apropiado (exacto, preciso y eficiente), se compararon dos métodos de transectos de banda: un transecto de tamaño sencillo (una sola banda de 30 x 2 m) y uno de tamaño mixto (dos bandas, una de 50 x 5 m para peces grandes y móviles, y una de 50 x 1 m para peces pequeños o crípticos). Tres observadores con diferente experiencia en censos visuales realizaron 72 censos en tres transectos fijos en...

Seasonality of Surface Chlorophyll in the Red Sea
Provedor de dados: 20
Autores: Ahmed, Mohammed Elamin Bashir Hassan.
Although the understanding of the oceanography of the Red Sea has been developed over the last few decades, but we still have a little knowledge about the influences of the physical factors on the phytoplankton activity. The purpose of the present study was initially to quantify and investigate the seasonal variation of surface chlorophyll concentration (CHL-a) at three zones in the Red Sea (north, middle and south). The second goal is to identify the controlling factors which seem to have an effect on the phytoplankton bloom during the same period of the study. To reach our goals, we use remote sensing data (surface chlorophyll, sea surface temperature and photosynthetically available radiation), oceanographic data (wind speed), and modeling data (mixed...

Autores: Simonazzi, M.
Estimations were made on the basis of a subsample of 6,734 individuals of Merluccius hubbsi from the Argentine Sea south of 41°S. Length-weight relation potential regression parameters were a=0.00950863, 0.01093448 and 0.01096117b=2.90831652, 2.86558431 and 2.86583191 for males, females and total individuals, respectively. The Newton algorithm was used to minimize the residuals. Maturity ogives were estimated with the logistic model adjusted by no lineal minimum quadratic ordinates. Length at first maturity at 50 was 33.79 cm for males and 35.38 cm for females. Age at first maturity estimated with the same model adjusted to the time elapsed from birth to catching was 2.61 and 2.67 years for males and females, respectively. Good fitting in all regressions...

Ultrastructural Of Oncorhynchus kisutch muscle development
Provedor de dados: 20
Autores: Rabah, S.
In a second study of electromicroscopic analysis of ultrastructural organelles of coho salmon muscle showed a significant increase in lipid droplet density in the largest stages compared with the smallest fish. The opposite was observed with the mitochondria where its density decreased in the large sized fish. An apparent decrease in capillary density with increasing body mass was also observed. These finding may imply a possible additional role of lipid depot as fish grew from parr to smolt.

The coastal area of Tanzania (Fig. 1) encompasses a number of habitats that include coral reefs, mangroves, seagrass beds, sand banks, wetlands and beaches, among others. In addition to being essential linkages in the overall functioning of the coastal area, these coastal habitats support various resources both living and non-living. In addition, for generations the coastal area has provided life support to coastal communities where such activities as fisheries and related activities have played an important role in the social and economic development of local communities. In recent years, coastal tourism and mariculture have immerged as being potentially among most important economic activities nationally. The well being of these habitats and resources...

The river basin has long been acknowledged as the appropriate unit of analysis for water resources management and has also been named by the United Nations Conference on Environment and Development (UNCED 1992) as the logical unit for integrated water resources management in Agenda 21, chapter 18. The comprehensive methodology framework for analysis structures the decision making process, starting with the problem identification, through the weighing of various options to the final selection of the most appropriate policy. The integrated planning approach methodology is applied to the 3600 km2 Nyando river basin in western Kenya, one of the sub-basins that drain into Lake Victoria in Eastern Africa. Statistical methods used to check the adequacy and...

Velocidades superficiales de las aguas fueron medidas en la Bahía chile en la Isla Greenwich, como parte de la Segunda Expedición Ecuatoriana a la Antártida, durante el verano del hemisferio sur, en 1990. Masas de hielo a la deriva desprendidas desde la costa fueron usadas como trazadores lagrangianos. Son comparadas corrientes superficiales y observaciones de vientos. La circulación superficial es determinada por los vientos cuando la velocidad de estos últimos exceden los 6 m/s. Los valores máximos y la dirección de la deriva superficial dependen exclusivamente del campo de viento prevaleciente. La velocidad de la corriente puede alcanzar valores de hasta 40 cm/s.

Consequences of the 1998 Coral Bleaching Event for the Islands of the Western Indian Ocean
Provedor de dados: 20
Autores: Quod, J.P.
Coral reefs are vital for coastal populations and for human activities in general, as they provide people both with living resources and with "services" such as shore protection, sand accretion and coastal tourism. The coral bleaching event of 1997-1998 summer is the most geographically wide spread and severe ever recorded. In the Indian Ocean, warm waters migrated from the South to the North during the first six months. As temperature stress was extreme and/or prolonged, mortality was catastrophically high in many areas (Kenya, Comoros, Seychelles, Tanzania, Maldives), the amount of dead corals ranging from 50-90%. Therefore, ITMEMS (International Tropical Marine Ecosystems Management Symposium) held in Townsville on 24 november 1998 recommended that a...

Institutions, mobility and resilience in the Fante migratory fisheries of West Africa
Provedor de dados: 20
Autores: Overå, R.
Through their spatial mobility, African fishermen and fish traders explore and exploit new niches: primarily fishing grounds and fish markets (see Chauveau 1991). Ghanaian canoe fishermen are among the groups most famous for such activity. In the twentieth century, they migrated extensively in coastal West Africa, reaching as far as Mauritania to the north and Congo to the south in order to fish in areas where the local fishermen have under-exploited their fishing grounds, and markets are unsaturated with fish (Delauney 1991; Boujou 2000). These migrants’ contributions in their host countries in terms of technological innovation in the fisheries, in terms of new knowledge and institutions, and not the least in terms of food supply, are increasingly being...

Influence of Coral Bleaching on the Fauna of Tutia Reef, Tanzania
Provedor de dados: 20
Autores: Öhman, M.C.; Lindahl, U.; Schelten, C.K.
In 1998, coral reefs of Tanzania were severely affected by bleaching. The coral mortality that followed caused a concern for coral reef degradation and overall resource depletion. In this study, we investigated coral bleaching effects on the coral reef fauna at Tutia Reef in Mafia Island Marine Park, Tanzania. Corals from adjacent reef patches of the species Acropora formosa were transplanted into plots, and reef structure and associated fish assemblages were examined before and after the bleaching event. Following the coral bleaching, 88% of all corals died. A year after the event, a large proportion of the dead corals was still standing. As surviving and dead corals were from different clones, results suggested that genetic variation might influence...

Aperçu sur les droits traditionnels de la pêche dans la législation sénégalaise
Provedor de dados: 20
Autores: Seck, A.
Le Sénégal est un pays de longue tradition de la pêche. Chez les lébous, les sérères mais aussi les autres peuples d’origine côtière, la culture traditionnelle de la pêche se transmettait de père en fils. De cette tradition de la pêche a découlé un droit traditionnel de la pêche. En effet, la particularité de l’accès au territoire de la pêche repose sur le fait qu’on ne l’obtient pas par l’acquisition. C’est la pratique qui, en fournissant la connaissance des lieux, des techniques et les habilités à la capture, garantit les droits d’usage. L’existence de ce droit traditionnel de la pêche est majoritairement acceptée au Sénégal. Cependant une controverse existe lorsqu’il s’agit d’aborder la question de la place qui doit être accordée à ce droit dans la...

El objective of this article was to show the impact of a cold  phenomenon such as "La Niña" during a multi-year period. The study was conducted by measuring the chemical characteristics of masses of water and comparing them to the characteristics shown in 2000 where the activity of this phenomenon was the strongest. The masses of water were located based on their characterization with parameters such as temperature, salinity, dissolved oxygen and inorganic micronutrients (phosphates, silicates, nitrites, and nitrates). These parameters were measured in 1994, a year considered as normal activity and in those years where "La Niña" was observed with greater intensity. The masses of water ATS, AES, ACP, AESS were established during the years of analysis. The...

Provedor de dados: 20
Autores: Gonçalves, P.M.B.; Pereira, M.A.M.
The use of gastropod shells by the hermit crab Clibanarius longitarsus at Costa do Sol Mangrove was investigated. Particular attention was paid to the influence of human collection of intertidal gastropod resources on the availability and utilization of shells by C. longitarsus. Three main methods were used in this study: crab field collections, shell selection laboratory experiments and interviews with local women who collect intertidal mollusk resources. A total of 23 shell types were used by C. longitarsus at the Costa do Sol mangrove, the most common being Volema pyrum, Murex brevispina and Terebralia palustris. Gastropod shells were a limiting resource for hermit crabs. Although shell availability could not be explained by human exploitation, which...

Standardized Catch Rates for Yellowfin (Thunnus Albacares) from the Spanish Pure Seine Fleet (1984-1995)
Provedor de dados: 20
Autores: Soto, M.; Morón, J.; Pallares, P.
The Spanish purse seine fleet operates in a wide area of the Indian Ocean since 1984. A logbooks system provides detailed information of catches (set by set) and effort. Together with this information, an intensive work of interview during 4 years (1994-1997) has provided technical equipment data. These data have been used to estimate standardized catch per unit effort (CPUE) indices of abundance for yellowfin from the Indian Ocean. Standardized catch rates have been estimated using the Generalized Linear Model (GLM) approach. The model proposed includes factors related with the stock abundance together with factors related with catchability changes.

There are different microbiological indexes to evaluate the trophic state of inland and coastal waters based on the direct relation between the concentration of organic matter and the heterotrophic bacteria. These indexes are valuable; however, as they were determined starting from data collected in tempered latitudes, if they are applied to tropical regions where heterotrophic bacteria concentrations are usually higher, the results can be underestimated. The objective of the present work is to elaborate a quantitative index to evaluate the trophic state from microbiological data collected in waters of the SW Cuban shelf. For this purpose, values of concentrations of heterotrophic (HB) and sulfate-reducing (SR) bacteria obtained in waters of SW Cuban shelf...

Autores: Essid, N.; Mahmoudi, E.; Beyrem, H.; Aissa, P.; Hedfi, A.
The survey of sediment and hydrological parameters in the old harbor of Bizerte has revealed that this ecosystem knows a high anthropogenic pressure. In this area waters were characterized by weak contents in dissolved oxygen and sediments, rich in fine fraction, were loaded in hydrocarbons and in organic matter. The free-living nematodes, predominant taxa, responded to these disturbances by a significant decrease in their densities and their biomasses and had tendency, notably at the most isolated sites, to penetrate deeply to escape surface sediments highly loaded in hydrocarbons and in organic matter.

Résumé : Des tests organoleptiques, physiques, chimiques et bactériologiques ont été effectués sur trois espèces de poissons de mer de Mauritanie : Syacium microrum (poisson plat) ; Pseudupeneus prayensis (poisson maigre) et Trachurus trachurus (poisson gras) stockés sous glace (0°C) et à température ambiante 22-28°C). Vingt quatre heures après leur capture, les poissons placés à température ambiante étaient déjà putrides (la flore dépassait 1010 UFC/g.  Les lots conservés sous glace étaient encore consommables après deux semaines de stockage. La glace retarde bien les phénomènes de vieillissement du poisson.

Autores: Zuñiga, M.; Ortega-García, S.; Arias-Aréchiga, J.
En el sur del Golfo de California, en el Puerto de Mazatlán, Sinaloa, el dorado(Coryphaena hippurus) soporta una pesquería artesanal y deportiva de gran importancia. Sin embargo, los estudios biológico-pesqueros para esta área son muy escasos. Durante el periodo de julio de 2000 a diciembre de 2001 se realizaron muestreos biológicos mensuales en las flotas deportiva y artesanal. Se encontró un intervalo de tallas de 47 a 164 cm de longitud furcal (LF) para la flota deportiva y para la flota artesanal de 38 a 137 cm LF. En promedio la captura en ambas flotas se sostiene por organismos entre 55 y 100 cm LF. El crecimiento del total de los organismos muestreados en ambas flotas fue alométrico. El resultado de la prueba T2 Hotelling demostró que existen...

Ostreopsis ovata fukuyo y O. siamensis schmidt,  dos nuevos registros de  dinoflagelados bentónicos tóxicos para Cuba
Provedor de dados: 20
Autores: Moreira  González, A.R.
Los dinoflagelados epibentónicos del género  Ostreopsis Schmidt  producen toxinas que están asociadas a la  ciguatera y a otros daños a la salud pública en las regiones tropicales y subtropicales. El presente trabajo  presenta dos nuevos registros de este género para Cuba:  Ostreopsis ovata Fukuyo y  O. siamensis Schmidt,  hallados en la provincia de Cienfüegos, región centro-sur del archipiélago cubano. Se observaron las  características que definen a ambas especies. Las células de O.  ovata se distinguen por la forma ovoidal- claviforme y pequeño tamaño. Las células de O. siamensis se identifican por la presencia de sólo poros grandes  en sus placas y la  típica ondulación en el cingulum. O.  siamensis  dominó  en el período seco, mientras que  posterior...

Autores: López-Garro, A.; Zanella-Cesarotto, Il.; Arauz-Vargas, R.
Sharks present strong intraspecific changes in feeding habits, which may vary according to size, geographic location and season. This study analyzed the stomach contents of 52 juvenile scalloped hammerhead sharks (25 females and 27 males) caught by artisanal vessels in the Gulf of Nicoya. Regarding the organisms found in the stomachs, 41.07 % were teleost fish, 30.36 % mollusks and 28.57 % crustaceans. Mollusks presented  the  highest  Relative Importance Index  (RII) (43.05  %), followed by teleost fish (41.37 %) and crustaceans (15.58 %). Squids (Loliginidae) were the items with the greatest RII (32.57 %). By means of the Pianka index, a relatively low overlap between sexes was identified, suggesting a  spatial sexual segregation and, in consequence, an...

Provedor de dados: 20
Autores: Fahmy, A.F.; El-Gharabawy, M.M.; Assem, S.S.
The grey mullet (Mugil cephalus) is one of the most common fish species in the Mediterranean Sea. Morphological and histological studies on testes of this species indicate six successive maturity stages. The specific changes in serum sex hormone levels were found to occur during the different phases of gonadal development. Concentration of serum steroid hormone in male Mugil cephalus revealed a marked drop in serum steroid (estradiol and testosterone) hormone levels in nearly ripe stage when compared with ripe stage, while the concentration of estradiol, testosterone and progesterone at late stage (ripe stage) of sexual maturity was increased. Histological examination and cyclic change in the testes were revealed of active spermatogenesis with all...

Influence of mesoscale atmospheric forcing on mean sea level at Piraquara, RJ
Provedor de dados: 20
Autores: Uaissone, A.J.R.
The work refers to variations of the mean sea level (MSL) in Piraquara (RJ) due to mesoscale atmospheric disturbances in the South and Southeast Brazil oceanic area. The sea level data were submitted to a verification and consistence process, and then they were  validated with the help of predicted levels by the software Pacmaré (FRANCO, 1992). For  the pressure and wind velocities, the NCEP re-analysis data was used. Thompson's low pass  optimizable filter was used to remove high frequencies in the data. Differently to the  habitual use of quarters of year in climatologic studies, in this work partitions of the year  centered in solstice and equinox were considered.  About the results of the statistical analysis in the time domain, it was seen that MSL...

National Report: The Marine Biodiversity of Mauritius
Provedor de dados: 20
Autores: Bhikajee, M.
The coastline of the island of Mauritius is 322 km long and is almost completely surrounded by fringing coral reefs enclosing a lagoon area totaling 243 km. The volcanic nature of the island's origin, the existence of coral reefs and the access to the lagoons of more than 50 rivers and rivulets, determine the diversity of the coastal habitats, flora and fauna. The island has several sandy beaches, protected bays and calm lagoons - factors that have favoured a prosperous tourism industry. Economically, the coastal zone is by far the most valuable segment of the Mauritian territory. Located here are the tourist facilities, secondary residences, ports, fisheries infrastructure and public beaches. Figure 3 gives the changes in coastal land distribution from...

Dans le but de mettre en évidence l’impact des modifications paysagères et la mécanisation des plages sur la faune carcinologique semi-terrestre, une campagne de terrain a été effectuée en février 2004 au niveau de deux sites de la province d’Alicante (Sud-Est de l’Espagne). La plage de Santa Pola, partiellement épargnée de l’accès des machines de nettoyage et celle d’El Pinet où la mécanisation est très intense. Les résultats obtenus ont montré que, malgré une faible densité des arthropodes récoltés, la biodiversité de la plage de Santa Pola est plus élevée que celle de la plage d’EL Pinet caractérisée par la quasi absence des amphipodes semi-terrestres. Seule l’espèce Tylos europaeus est commune dans les 2 sites. Ce résultat s’expliquerait par l’impact...

The evaluation of the possible environmental changes due to the anthropic impacts that have happened in the last years in this scenario and the redefinition of areas that suffer affectations were carried up. Any environmental alteration of this ecosystem, either of natural or human origin, can have an important economic and social repercussion. According to the proposed chemical and biological indexes, the waters of the Gulf of Batabanó presented mesotrophic conditions with tendency to the eutrofization in four fundamental areas. In the silts of the Gulf the values of organic carbon and sulphidric acid were characteristic of sediments with high concentrations of organic matter. In the coastal sector N, was determinate high concentrations of sulphidric acid...

Updated standardized CPUE of bigeye caught by the Japanese longline fishery in the Indian Ocean.
Provedor de dados: 20
Autores: Okamoto, H.; Miyabe, N.
The catch per unit of effort (CPUE) of bigeye caught by the Japanese longline fishery in the Indian Ocean was standardized up to 1997 using general linear model (GLM) analysis. Standardized CPUE in the tropical area, which was relatively stable, ranged from 6 to 8 fish per 1,000 hooks in 1979-1987 and decreased continuously to about 4 in 1997. In contrast, CPUE in the southern area did not show the stable trend of the tropical areas, especially after 1990. This unstable CPUE pattern in the southern area in recent years seems to be derived mainly from the shift of targeting in longline operations. If the trend derived from analysis for 1952-1976 is included, current CPUE is estimated to be about 33 % of that in 1954.

Bioestratigrafía basada en cocolitofóridos y paleoceanografía del Pacífico Ecuatorial Oriental
Provedor de dados: 20
Autores: Zurita, G.
Cerca de 200 muestras de cuatro muestreadores de pistón provenientes de ambos flancos de la Cordillera Submarina Carnegie, Pacífico Ecuatorial Oriental, fueron analizadas. Cocolitofóridos fueron usados para el estudio bioestratigráfico. La presencia o ausencia de las distintas especies no concuerda con los ciclos climáticos. Las variaciones del contenido de carbonato de calcio, obedecen a mayor o menor disolución durante épocas no glaciales o glaciales respectivamente. La preservación de cocolitos y el aparente alto contenido del carbonato de calcio antes de 251.000 años sugiere poca variación de condiciones climáticos, correspondiendo a una menor disolución de material calcáreo.

Mediterranean Marine Protected Areas And Fisheries Reserves
Provedor de dados: 20
Marine protected areas (MPAs) are defined as “Any area of the littoral or subtidal terrain, together with its overlying water and associated flora, fauna, historical and cultural features, which has been reserved by law or other effective means to protect part or all of the enclosed environment” (Kelleher and Kenchington, 1992). This definition includes intertidal reserves, as well as areas for the protection of shipwrecks and archaeological remains. Marine protected areas are designated to conserve the diversity of life according to the three aspects of Biodiversity: ecosystems diversity (habitats and species), species richness and genetic diversity. Also MPAs play a key role in promoting sustainable development. They are designed to enhance the...

Water hyacinth: an environmental disaster in the Winam Gulf of Lake Victoria and its control
Provedor de dados: 20
Autores: Ochiel, G.R.S.; Mailu, A.M.; Gitonga, W.; Njoka, S.W.
Water hyacinth has in the recent past had an adverse socio-economic impact on the lakeshore communities of Lake Victoria, particularly in the Winam Gulf. Fishing, lake transport and water supply have been seriously affected by the water hyacinth. KARI’s efforts at mitigating this disaster have so far been in the form of a twopronged management strategy consisting of physical and biological measures. The local administration has been involved in mobilizing the local communities to remove water hyacinth manually at strategic sites. However, there have been a number of constraints, mainly community attitudes to self-help activities. The Kenya Industrial Research and Development Institute (KIRDI) has developed a prototype mechanical harvester in a KARI-funded...

Provedor de dados: 20
Autores: Perrotta, R.G.
The polaca (Micromesistius australis)is a typical fish from the cold Malvinas current (temperatures between 3° and 10°C). The species is found in depths between 90 and 800 m and in latitudes from 37°40' to 50° S during winter and spring and from 42°S to 55°S during summer time, over the patagonian shelf and Burdwood Bank. One part of the stock reaches the southern region of the Scotia Sea, the western South Georgias and eastern South Shetland Islands. The dominant food species are Euphausia spp. The polaca is mainly a carcinophagous fish and may be found in a 3-4 trophic level, being one of the main food sources for primary and secondary ichthyophagous fishes.

Within the frame of the National Program (PNM), 'Assessment of Marine Tunisian Resources' (1996-1999), two prospecting surveys on small pelagic fishes, have been led in narrow collaboration with French Institute IFREMER. Their objectives were to specify the relative fishes abundance, their spatial-temporal variability but also to quantify the maximum sustainable yield (MSY) of this resource. A third important goal was to familiarize a Tunisian scientist team, with numerical methods and data processing used during the cruises (reading of echograms, treatments of data, etc.) in stocks assessment. It is known that the indirect stocks assessment methods of small pelagic species is not reliable, reason for which we opted to apply echo - integration techniques....

Autores: Awosika, L.F.
The continental shelf east and west of Lagos [long.2o.04.00E to long.4o 00’.00”E] is narrow shelf ranging in width between 25 to 30 kilometers. Echograms from several NIOMR’s cruises reveal the presence of some isolated and in some cases continuous bands of dead Holocene coral banks, within the middle to outer continental shelf [40-120m depth]. The most prominent of these structures are ones occurring between 75-100m of water and running almost parallel to the coastline. The dead coral structures are non-reef forms. They are found either as continuous Bands of rough bottom with width ranging between, 100 to 3,500m or in isolated pinnacled shapes. The pinnacled forms reach heights of over 7 meters in some cases. These coral structures pose obstructions to...

Crustaceans are harmed rapidly due to the post mortem different processes, specially the dark spot knew as melanosis or enzymatic darkening. Those spots are controlled by the sulfite treatments, but the potential dangers associated with the use of these compounds oblige to develope rigorous control methods. Besides, in these species are observed texture affectations during the storage time, changing to pasty mass and reducing its commercial quality. For these reasons, it was realized a durability study, analizing chemical, microbiological and sensorial parameters to the frozen products raw lobster tails and tail mass. The results indicated a shelf life of 21 months for the lobster tails and 18 months for the tails mass.

Going against the flow: Effects of river damming in Cuban fisheries
Provedor de dados: 20
Autores: Baisre, J. A.; Arboleya, A.
Over the last decade eutrophication of freshwater artificial reservoirs in Cuba occurred in parallel to oligotrophication of estuarine and coastal waters. These two processes influenced both freshwater and marine fisheries. A dramatic shift in species composition in freshwater fisheries has occurred, from dominance by cichlids (tilapia) to dominance by cyprinids. The high fishery yield from some reservoirs, and shift in species composition, seems related to progressive eutrophication of reservoirs by nutrient subsidies from different anthropogenic activities; particular those related to the size of urban areas within their watersheds. On the other hand, marine landings of estuarine-dependent species declined more significantly than for other groups...

Cette thèse étudie le problème de la gestion des pêches au sein d’une AMP, en tenant compte du système économique global ainsi que des transformations structurelles qui affectent celui ci, et en diversifiant les critères de gestion. Le cas d’étude est la RBDS (Sénégal). Une enquête de terrain montre que la population de cette localité diversifie ses activités essentiellement entre l’agriculture, la pêche et le tourisme. Une analyse économétrique indique que la démographie, la sécheresse et la baisse du prix de l’arachide sur le marché mondial sont les principales causes de la crise agricole dans la région. Cette crise favorise la diversification vers la pêche. Un modèle théorique étudiant ce processus montre qu’il conduit la pêche à l’équilibre de libre...

La población de estudio se caracteriza por poseer colonias medianas (alrededor de 3379 cm2), con mortalidad parcial en 27 % de los ramets y totoal en el 10 % de los mismos. Las colonias presentan un alto número de ramets pequeños producto de la fisión (76 % menores a 50 cm2). Basado en las características de la estructura de tallas de la población mencionada, el objetivo de esta investigación fue explicar el bajo reclutamiento registrado en la zona, a través de la respuesta reproductiva de una población con dominancia de ramets...

Descripción morfológica e histológica del aparato digestivo del calamar Illex argentinus (Cephalopoda: Ommastrephidae)
Provedor de dados: 20
Autores: Ivanovic, M.L.; Brunetti, N.E.
The morphology and histology of the digestive tract of the Argentine short-finned squid Illex argentinus are described. The structures involved are the buccal mass, oesophagus, vestibulum, stomach, caecum, intestine, digestive gland and digestive duct appendages. A differential development of the tissular components in relation to the function of each organ is observed. The musculature of the buccal mass, oesophagus and stomach, organs involved in the mechanical degradation of food is strongly developed. This development is weaker in the caecum where enzymatic digestion and absorption take place and in the intestine. For the same reason, the epithelia of the mucosae of the oesophagus and stomach secrete a thick cuticle whereas those of the caecum and...

Kenyan Exports of Nile Perch: impact of food safety standards on an export-oriented supply chain
Provedor de dados: 20
Autores: Mitullah, W.; Henson, S.
Over the past decade, exports of fish and fishery products from developing countries have increased rapidly. However, one of the major challenges facing developing countries in seeking to maintain and expand their share of global markets is stricter food safety requirements in industrial countries. Kenyan exports of Nile perch to the European Union provide a notable example of efforts to comply with such requirements, overlaid with the necessity to overcome restrictions on trade relating to immediate food safety concerns. Although food safety requirements were evolving in their major markets, most notably the EU, most Kenyan exporters had made little attempt to upgrade their hygiene standards. Likewise, the legislative framework of food safety controls and...

There is a lack of scientific information about the artisanal fishery in the de la Costa County (Buenos Aires province, Argentina). Moreover, this artisanal sector does not have fishing statistics because local fishermen are not obliged to hand in fishing reports, where even basic data on catch and fleet effort should be included. The main objective was the analysis of the artisanal fishery in the de la Costa County from the biological, economic and social point of view. One 132 sample stations were analyzed between 56 degree -57 degree W and 36 degree -37 degree S from 1992 to 1999. Moreover, information on the artisanal fleet, environmental conditions and the arrival of tourists to the de la Costa County was also analyzed. Fishing yield (FY) per boat was...

Instructions to the Marine Meteorological Observers of the U. S. Weather Bureau, 6th edition
Provedor de dados: 20
The ocean meteorological program of the Weather Bureau has two separate and distinct parts. First, there is the daily service by radio. Owing to the need for brevity, the radio reports contain a limited amount of essential information. The daily weather reports from ships and islands reveal the conditions over the ocean; when assembled on a map, including continental reports, they give a picture of weather conditions existing momentarily over a large region. A collection of observations is immediately returned to the mariner by radio broadcast so that he may draw his own weather map on shipboard. By this process, the weather at the earth's surface is mapped and much can be inferred as to conditions above the surface. Formation and movement of storms are...

Aspectos biológicos y ecológicos de Mytilopsis sallei (Recluz, 1849) (Bivalvia: Dreissenidae) en bancos de ostra de la Ciénaga Grande de Santa Marta, Caribe colombiano
Provedor de dados: 20
Autores: Puyana, Mónica.
Mytilopsis sallei es una especie que se encuentra ampliamente distribuida sobre sustratos duros en la Ciénaga Grande de Santa Marta, siendo particularmente abundante sobre bancos de ostra de mangle (Crassostrea rhizophorae), donde alcanza densidades de hasta 5000 indiv/m2. Aunque posee una amplia tolerancia a variaciones en la salinidad y temperatura, prefiere aquellos lugares donde la afluencia de aguas dulces es constante. Puede además tolerar aguas turbias con un alto contenido de sedimentos, como en la desembocadura de los ríos. M. sallei no parece aparentemente, competir con la ostra, incluso en aquellos bancos sometidos a intensa explotación. Esto se debe a las preferencias ambientales de cada especie y a la alta productividad de las aguas de la...

Provedor de dados: 20
Autores: Huang, Deyin; Shi, Qi; Zhang, Yechun.
According to the field survey and 14C dating at Luhuitou, southern Hainan Island, a subsiding area, the authors conclude the high sea level history recorded by coral reef in the Holocene. At least 4 sea level high-stands can be identified from the distribution of coral reef ages: 7300 - 6000 cal.aBP, 4800 - 4700 cal.aBP, 4300 - 4200 cal.aBP and 3100 - 2900 cal.aBP. The highest sea level occurred around 7300 - 6700 cal.aBP, and biological-morphological zones took their shape during the stage. The later coral reefs developed in ponds, depressions, and developed outwards on both sides of Luhuitou peninsula. The modern coral reefs are developing in out reef flat and reef-front slope. Moreover, the time of high sea levels in the northern South China Sea...

Provedor de dados: 20
Autores: Thonnon, J.; Diallo, M.; Traore-Lamizana, M.; Fontenille, D.
Chikungunya fever is a viral disease transmitted to human beings by Aedes genus mosquitoes. From 1972 to 1986 in Ke´dougou, Senegal, 178 Chikungunya virus strains were isolated from gallery forest mosquitoes, with most of them isolated from Ae. furcifer-taylori (129 strains), Ae. luteocephalus (27 strains), and Ae. dalzieli (12 strains). The characteristics of the sylvatic transmission cycle are a circulation periodicity with silent intervals that last approximately three years. Few epidemics of this disease have been reported in Senegal. The most recent one occurred in 1996 in Kaffrine where two Chikungunya virus strains were isolated from Ae. aegypti. The retrospective analysis of viral isolates from mosquitoes, wild vertebrates, and humans allowed to us...

Long tailed hake Macruronus magellanicus, is a demersal fish,distributed in the SW Atlantic Ocean, in Malvinas Current waters,from 36° and 55°S, mainly between 50m and 200m depth. The species is also distributed in Chilenian waters in the Pacific Ocean, being caught in the Magellan Strait and the Beagle Channel. Age determination was estimated with the sagittae otoliths, in which only one ring is formed during the year. Growth parameters were calculated directly and with back calculated methodology, no differences were observed between the results. Differences in growth sexes were evident from 3 years old. The oldest age observed was 13. Different distributional areas of adults through out the year could suggest a migratory movement in northern waters of...

On the fish catch and discard of the shrimp fishery of Nigeria
Provedor de dados: 20
Autores: Ajayi, T.O.; Adetayo, J.A.
Commercial landings and effort data over the period 1970-1980 as well as shrimp research vessel catches were analysed.  Both shrimp and fish by-catch consistently showed seasonality in abundance. However, while shrimp catches declined from 49.20% of total in 1979 to 13.795 in 1980, incidental fish landings rose proportionately.  The fish shovelled overboard measured 18.0cm or less in total length.  Prominent among these were Brachydeuterus auritus, Ilisha africana and Vomer setapinnis.  The fish discard amounted to 43.68% of the total catch.

Autores: Geister, J.
Colecciones realizadas en los complejos arrecifales pleistoceno y reciente de la Isla de San Andrés rindieron 38 especies pleistocenas y 121 especies recientes de moluscos marinos. En la distribución ecológica de las especies recientes están representados los biótopos costa rocosa , corales, arena, mangle, terrazas submarinas rocosas y agua profunda. Los hallazgos pleistocenos se restringen a los biótopos costa rocosa, coral y arena. El menor número de especies en la fauna pleistocena se explica parcialmente por la falta de los otros biótopos, pero en primer lugar por la ausencia de las formas de agua poco profunda. Colecciones cuantitativas en los biótopos de arena pleistoceno y reciente , muestran una composición faunística bastante diversa, lo que...

Abundance and Reproductive Biology of the Penaeid Prawns of Bagamoyo Coastal Waters, Tanzania
Provedor de dados: 20
Autores: Mgaya, Y.D.; Teikwa, E.D.
The coastal waters of Bagamoyo in Tanzania constitute an important penaeid prawn trawling ground. Despite the high economic value attached to this resource, the biological information necessary for its sustainable exploitation is scanty and fragmented. The present study was therefore designed to investigate the species composition, population abundance and reproduction of the penaeid prawns in Bagamoyo coastal and nearshore waters. Samples were obtained monthly for a period of one year from inshore waters adjacent to the Ruvu Estuary while additional samples were bought at the beach from artisanal fishermen. In the laboratory, samples were identified to the species level. Four penaeid species, Fenneropenaeus indicus (formerly known as Penaeus indicus...

The analytical framework used throughout most of this study is directly inspired from transaction-cost economics, implying that a lot of attention is devoted to monitoring and enforcement costs involved in collective schemes. One of its most important contributions is to show that, with the help of these tools combined with conventional market power considerations, successes and failures of different groups of fishermen according to their technique and site of operation can be well accounted for. The outline is as follows. In Section 1, background information regarding Senegalese small-scale marine fisheries are provided and the methodology of the study based on cross-section data is shortly described.

Autores: Moreno, V.J.; Aizpun, J.E.; Malaspina, A.M.
Seasonal variations in major biochemical compoenets (lipids, protein and water)as well as in ash content of muscle and filletin remains of Engraulis anchoita were studied separately along three consecutive fishing seasons (May-December 1975, 1976 and 1977). Five to ten adult fish of each sex and of nearly identical length (total length: 160-165 mm)were selected at approximately monthly intervals from commercial catches at Mar del Plata Harbour. During the course of the three sampling periods, the proportions of the different biochemcial components showed a very similar pattern of variation and the difference from one fishing season to another never exceeded one month.

Estructura por edad y sexo de la captura de merluza desembarcada. Período 1986-1998
Provedor de dados: 20
Autores: Renzi, M.A.
During the 1986-1998 period the hake (Merluccius hubbsi) fishery in the Argentine Sea (SW Atlantic) turned from moderate to intense exploitation. Age and sex structure analysis showed a change in the exploitation pattern. During the three periods defined  1986-1989, 1990-1992 and 1993-1998 a trend towards catching young individuals and a predominance of females age 3 and older was observed. An increase of total mortality was also detected. As a consequence of the establishment of a closed area in mid 1997 ice-chilling and freezer fleets changed operation areas which brought about differences in the catch structure. Freezers showed higher percentages of older ages. An average decrease of 30 in yield number of individuals per unit effort for all ages was...

The distribution of chlorophyll-a concentration in the austral Patagonian (SW Atlantic Ocean) shelf between 47º S-54º S with in situ data collected in March-April 2000 is analyzed. Data derived from Niskin samples and continuous in situ fluorometry. Two areas with high chlorophyll values (~- 1.6 mg m-3) on the central shelf corresponding to the area between isolines 100-150 m depth and near the coastal region off Bahía Grande south of the Santa Cruz river (Argentina) were identified. Minimum values (~, 0.5 mg m-3) were found in the coastal zone close to the 50 m isobath and to the southern region of the Patagonian shelf. Fluorescence: chlorophyll-a concentration ratios were more variable at sea surface than at different depths of the water column. The...

Las toxinas marinas han proporcionado una variedad de compuestos capaces de ejercer acciones específicas y potentes a nivel de canales iónicos activados por voltaje o por neurotransmisores. Puesto que los canales iónicos participan en los mecanismos básicos de funcionamiento del sistema nervioso y que alteraciones funcionales y estructurales asociadas a éstos pueden correlacionarse con diferentes patologías neurológicas, neuromusculares y cardiovasculares, las toxinas pueden jugar un papel muy importante tanto como reactivos biológicos para la investigación biomédica, como para el diseño de nuevos fármacos a emplear en la terapéutica médica.

Autores: Koné, Vamara.
L'influence de la température sur la mortalité des oeufs d'anchois dans l'écosystème du Benguela sud apparaît très variée. Les simulations ont montré une sensibilité à la valeur seuil de température létale, une variabilité de l'indice de mortalité en fonction de la zone, de la période et de la profondeur de ponte. L'approche IBM utilisée dans le cadre de cette étude est un bon outil d'investigation des processus essentiels, aussi bien physiques que biologiques, qui contrôlent le transport des oeufs et des larves de la zone de ponte à la zone de nourricerie sur la côte ouest. Cette étude est applicable aux ressources des petits pélagiques associés à l'upwelling Ivoiro-Ghannéen au nord du golf de Guinnée.

What do we know about El Nino in the Indian Ocean? A
Provedor de dados: 20
Autores: Le Blanc, J.-L.
This paper aims to guide fisheries biologists in the use of current knowledge of the El Niño-Southern Oscillation (ENSO) phenomenon in order to address its impact on fisheries in the Indian Ocean. It is widely accepted that both the Indian and the Pacific Oceans are closely linked through the Indonesian Throughflow and the strong convective activity that occurs there. In order to tackle the ENSO phenomenon, it is therefore crucial to adopt a coupled Indian-Pacific Ocean approach. ENSO mechanisms in the Pacific are well known, but the role of the Indian Ocean in these mechanisms is not as clear. Due to the fact that air-sea interactions in the Indian Ocean are a new area of research, our knowledge is still not sufficient to have an overall view of the...

La grille du modèle des côtes Tunisiennes comporte la ossibilité d’augmenter la résolution dans un domaine ciblé. Les conditions initiales pour ce modèle étiré sont obtenues par interpolation des états simulés par le modèle côtier à résolution constante. Vu sa résolution plus élevée, le modèle à grille étirée nécessite un long temps de calcul. Cependant les tests effectués avec ce modèle montrent que des simulations de 20 jours suffisent pour atteindre un équilibre...

The Relationship of Sulfate-methane Interface, the Methane Flux and the Underlying Gas Hydrate.
Provedor de dados: 20
Autores: Fang, Yinxia; Chu, Fengyou.
The sulfate-methane interface is an important biogeochemical identification interface for the areas with high methane flux and containing gas hydrate. Above the sulfate-methane interface, the sulfate concentration in the sediment is consumed progressively for the decomposition of the organic matter and anaerobic methane oxidation. Below the sulfate-methane interface, the methane concentration increases continuously with the depth. Based on the variation characters of the sulfate and methane concentration around the sulfate-methane interface, it is feasible to estimate the intensity of the methane flux, and thereafter to infer the possible occurrence of gas hydrate. The geochemical data of the pore water taken from the northern slope of the South China Sea...

Une étude microcosmique a été effectuée pour examiner l’influence d’un lubrifiant minéral avant et après son utilisation dans un moteur de véhicule  sur la structure trophique de la communauté de nématodes libres originaire de la lagune de Ghar El Melh. Une concentration de 1mg kg-1 de sédiment a été testée pour évaluer l’effet du polluant après 40 jours d’exposition. Les résultats de l’étude ont révélé que les consommateurs non sélectifs (1B), les plus abondants dans le microcosme témoin, ont été très affectés et leur dominance a diminué significativement sous l’effet de la contamination par le lubrifiant minéral avant ou après usage. Les détritivores sélectifs (1A) dont la dominance augmente significativement au iveau des microcosmes traités avec le...

Community Participation in the Planning and Management of Marine Protected Areas: A Study Of Kenya and the Philippines
Provedor de dados: 20
Autores: Ole-MoiYoi, L.K.
For countless centuries, fishing-dependent indigenous communities have protected their marine environments from over-exploitation. Understanding that proper conservation guaranteed food for future generations, many of these communities fished only during certain times of the year, or divided up fishing grounds based on familial ties. However, as these communities lost water rights following the formation of certain nation-states, and international fishing fleets moved into the world’s oceans, a need arose to devise new techniques for protecting marine environments. Not only is this protection necessary to maintain biodiversity, but also to guarantee food security and the cultural traditions of fishing villages around the world.  In 1957, British biologists...

Autores: Arcos, F.; Córdova, Jorge L.
Se analiza la distribución horizontal y vertical de clorofila a proveniente de 23 estaciones con cuatro niveles de muestreo en el Estrecho Bransfiel durante el verano austral de 1987-1988. Se encontró que heterogeneidad en la distribución y ésta se relaciona con la temperatura superficial así como con los valores de oxígeno disuelto, determinando estrecha relación entre estos parámetros. Los valores elevados de pigmento se restringieron al norte del estrecho, donde la temperatura y oxígeno también fueron relativamente altos. Análisis clorofílico en bahías cerradas reportó también altos valores, siendo el mayor, el encontrado en Bahía Arthur en la Isla Anvers, al sur-oeste de Bransfiel.

The total length distribution of pink cuskeel Genypterus blacodes catches is difficult to obtain. On the contrary, it is easy to have access to the head length distribution. So, the purpose of this study was to obtain a relationship between a certain head measurement and total length to estimate the length distribution of the catches. Individuals were obtained from bottom-trawl surveys between 39°-47°S and the San Jorge Gulf of the Argentine sea. Sets of measurements of total length (LT), maxillar length (Lmax), head length (Lc),orbital length (Lo), preorbital length (Lpo) and head length-total length ratio (r=Lc/LT) by sex were obtained. The total length was estimated with a regression model using the head length as independent variable. No significant...

Kinetic and isotherm studies of copper (II) removal from wastewater using various adsorbents
Provedor de dados: 20
Autores: Abdel Wahab, O.
The present investigation deals with the utilization of marine green algae (GA), Ulva lactuca, and an activated carbon prepared from green algae (CGA) as adsorbents for the removal of copper from wastewater. A series of experiments were conducted in a batch system to evaluate the effect of system variables. The effect of pH, initial copper concentration, dose of adsorbents were considered. The optimal pH value of copper (II) adsorption onto GA and CGA was found to be pH 5.0. The maximum uptake capacities were 24.5 and 32.3 mg copper (II) per gram of GA and CGA, respectively. The efficiency of removal was slightly changed by replacing an aqueous solution by saline water or wastewater containing the same copper concentration. Adsorption kinetic data were...

Autores: Jia-xun, Li; Ren, Zhang; Chen-zhao, Liu; Hong-jun, Fan.
Aiming at the influence of ocean mesoscale eddy on underwater acoustic propagation, a theoretical computation model of ocean mesoscale eddy was established based on the in-situ hydrographic data in the sea area of ocean mesoscale eddy. An underwater acoustic model-MMPE was used to simulate the acoustic propagation under the influence of different types, different intensities and positions of eddies, and different frequencies and depths of sources. It is found that warm-core eddy can make the convergence zone "move back" and the width of it increases, while cold-core eddy can make the convergence zone "move forward" and the width of it decreases. The bigger the intensity of eddy, the more notable the "forward "or "back "effect. Sound source located depths...

In 1929, it was first reported that Listeria monocytogenes could cause disease in humans. In 1980, there was an outbreak of the disease in Auckland, New Zealand resulting in 5 deaths and 22 perinatal cases. Investigators suggested that the consumption of raw seafood may have been a contributory factor. This evidence was epidemiological rather than microbiological. There are a number of different ways by which Listeria monocytogenes and other pathogenic organisms can enter into the seafood processing plants and contaminate fish and seafood products, the main ones being run off from agricultural farms, direct faecal contamination by animals (man inclusive), sewage and seafood contact surfaces. Quantitative ATP bioluminescence, RODAC and TVC was used to...

Towards the development of environmental indices for the Namibian shelf, with particular reference to fisheries management.
Provedor de dados: 20
Autores: Bartholomae, Ch.; Van der Plas, A.
The Namibian Ministry of Fisheries and Marine Resources has the task of collecting and providing relevant oceanographic information for management of their fisheries. However, quality information is difficult to provide because of the complexity of the processes involved in the Namibian marine ecosystem. Nonetheless, there are oceanographic data available that can contribute to fisheries management by improving the general understanding of important oceanographic processes related to fisheries. The focus of this paper is on the development of simple environmental indices that can serve as a measurement or proxy of the state or intensity of certain important oceanographic processes or variables for temporal comparison. These indices relate to oceanographic...

Provedor de dados: 20
Autores: Wood, C.D; Boustead, P.; Mora, Y.; Grijalva, M.
En los últimos años han habido evidencias del aumento de exportaciones por vía aérea de pescado fresco. Los desembarques artesanales se destacan en este aumento, particularmente de dorado, y el incremento de las exportaciones estimula también alguna diversificación de productos. Una mayor limitación a más exportaciones se entiende de la competencia para espacio restringible de flete aéreo entre los exportadores de productos perecederos (pescado, flores, frutas, etc.), y de la necesidad de coordinar el reparto y la extensión de la capacidad de carga. Las actividades de pesca y comercialización están muy fragmentadas, y resultó que esta industria compleja era dificil de controlar. Esta es la razón para estudios de este tipo, para actualizar y ampliar la...

Autores: Madirolas, A.
Two joint Argentine-British acoustic surveys specifically targeted on the southern blue whiting (Micromesistius australis) were carried out during September 1994 and 1995. The surveys confirmed the existence of a spawning concentration area located south from San Carlos Strait, in waters south of Malvinas Islands, ASW. The obtained point estimates of blue whiting abundance were 84801 t for the 1994 survey and 140953 t for the 1995 survey. The surveys also provided information on the school structure and behavior as well as some clues about the complex migration pattern of the species.

The communities do not have a compression of the environmental on the resource, as well as the fragility of the coastal ecosystems. Between the negative effects over the environmental are the indiscriminate cutting, the pollution, all of them due to the ignorance of the mangove forests benefits. The economic activities are industrialists and agriculturists where the spiny lobster fishery (P. argus) is the most important. A decrease of the level of captures from 1990 to 2003, was observed. This behavior reflects the deteriorate conditions of the environment, which limit the recruitment and affect some nursery areas, as well as the...

Preliminary study on the food and feeding habits of Schilbe mystus (Linn., 1762) in River Nyando
Provedor de dados: 20
Autores: Omondi, R.; Ogari, J.
Schilbe mystus (butterfish) is one of the "endangered species" of Lake     Victoria, whose fishery was once of commercial importance. The annual     landings have declined from about 400 mt in 1968 to a bare 15 mt in     1991. The average size of the species is smaller than that reported by     Greenwood (1966). During the study, the size range sampled was 11.2 to     25.6 cm fork length with the majority measuring 14.0-15.0 cm FL. The     food and feeding habits of the fish are discussed. Study on the gut     content shows that S. mystus preys mainly on insects with chironomid     larvae as the dominant prey.

La producción de triploides mediante la manipulación de ploidías por métodos químicos ha demostrado ser un éxito en la producción comercial de varias especies, siendo el caso más conocido el del ostión japonés Crassostrea gigas. La ventaja de los triploides de moluscos sobre los organismos diploides se debe a su alta tasa de crecimiento, resultado de ser total o parcialmente estériles. Los triploides son incapaces de realizar la meiosis I debido a que sus cromosomas (impares) no pueden completar la sinapsis durante la profase, fallan en la producción de gametos y la energía que sería utilizada para la gametogénesis se invierte alternativamente en crecimiento somático.

Environmental effects of Coastal Sedimentation: A Case study fo Shirazi-Funzi Lagoon
Provedor de dados: 20
Autores: Munyao, T.M.
Shirazi-Funzi Lagoon is situated about 70km Southwest of Mombasa. It occurs within longitudes 39°22'E and 39°27'E, and latitudes 4°30'S and 4°35'S and covers about 57km2. The study area lies in the coastal plain, wich is below the 30m contours, and is underlain by coral limestone of the Pleistocene age, and lagoonal deposits from both land and sea. Both the hinterlands at Shirazi and the Funzi Island are underlain by the MtoMkuu formation of upper and lower Cretaceous, of the Post Karoo systems. This formation is overlain by Pleistocene sands that cover the Funzi Island and a narrow strip of the coastline immediately north of Funzi Island.

Improvements in the Ghanaian tuna statistics system
Provedor de dados: 20
Autores: Quartey, R.; Bannerman, P.
Light fishing operations (LFO) in Ghana is concentrated in the three major coastal municipalities of Greater Accra (Tema), Central (Mumford &amp; Elmina) and Western (Sekondi) Regions; these areas have the port facilities for landing of the catch by the larger inshore vessels that operate the purse seine fishery in Ghana and which predominantly operate the light attraction. Currently there are about 250 registered inshore vessels in the country whose sizes range between 39 – 60 feet , only a small fraction are actually working at the moment due to problems with spare parts and operations. Light attraction is the technique of aggregating fish by artificial light; and light fishing is the process of fishing the attracted fish by hooking, gill-netting or by...

Dynamics of ENSO events in the Indian ocean: To what extent would recruitment and catchability of tropical tunas be affected ?
Provedor de dados: 20
Autores: Marsac, F.; Le Blanc, J.-L.
In this paper, the authors explore functional relationships between environmental fluctuations and some key parameters used in stock assessment such as recruitment and catchability. Yellowfin tuna (Thunnus albacares) is taken as an example but the concepts developed in this study could be widened to other tropical tunas. The French purse seine data-set is used to estimate a recruitment index from adjusted CPUE of age 0 fishes, and the effect of the environment on catchability is assessed using CPUE of age 3 fishes which provide the bulk of adult catches. The ACE algorithm is used to describe a non-linear relationship between the recruitment and the turbulence (wind speed cubed). There is a detrimental effect of an increasing turbulence on recruitment. The...

Resultados de una campaña de investigación sobre la anchoíta (Engraulis anchoita)del sector bonaerense en el otoño de 1983. Distribución, abundancia y algunos aspectos biológico-pesqueros
Provedor de dados: 20
Autores: Hansen, J.E.; Gru, D.L.; Perrotta, R.G.
An extensive area of the continental shelf -between 37°20' and 34°40'S - was reviewed through hidroacoustical methods in order to evaluate the anchovy biomass. Within the area of highest concentration, further data on anchovy abundance were recorded, and fish samples were taken. Large anchovy shoals were located at about 170 nm from Mar del Plata, mainly in zones with sharp changes in oceanographic conditions. The distribution of the species was not uniform, but "contagious", and the log-normal distribution provided the best fit for the echo-integrator recorded data. The biomass was estimated at 1,061,727 tons (Confidence limits in between 921,010 and 1,223,930 tons). Some parameters of the population were estimated, such as: lenght-weight relationship,...

L’allache ou sardinelle ronde (Sardinella aurita, Valenciennes, 1847) est une espèce de la famille des Clupeidae à affinité intertropicale. Cette espèce est la plus représentée dans les produits de la pêche en Tunisie. Dans cette étude on a évalué la qualité nutritionnelle de ce poisson en évaluant sa richesse en oligo-éléments et en acides gras. Pour ce fait, on a suivi les concentrations saisonnières de ces éléments dans quatre organes dont certains sont les plus consommés à savoir la chair et les gonades. Par contre, d’autres sont facultativement consommés par les habitants de certaines régions de la Tunisie notamment le cerveau et le foie. Les échantillons de la sardinelle ont été collectés mensuellement auprès des embarcations professionnelles...

Renewable natural resources constitute major sources for socioeconomic development of all developing countries, if they can be con-served, developed and sustainably exploited. For its strategic conservation and sustainable exploitation, biodiversity has to be investigated and documented at various levels and in an internationally accepted manner. However, the human and material resources available in the developing countries are insufficient to under-take the necessary studies, while various forces continue to degrade or erode biodiversity; The obvious solution is through collaboration in research and training.

Integrated Framework For Technical Assistance For Trade Development In Least Developed Countries - Mauritania
Provedor de dados: 20
Autores: Ataman Aksoy, M.
The Integrated Framework (IF) was established by WTO trade ministers in 1996 to promote the integration of the least developed countries (LDCs) into the global economy.1 This was in response to the slow progress of the LDCs in successfully integrating into the world economy. Participating agencies include the WTO, the IMF, the International Trade Center, UNDP, UNCTAD, and the World Bank (WB). Progress in mobilizing donor support proved difficult, and the program started slowly. An independent review of the IF, completed in June 2000, highlighted the lack of linkages to overall development strategies or programs and the absence of donor resources. Following the meeting of the Heads of Organizations last summer, the IF was redefined to ensure better...

Light microscope study of Oncorhynchus kisutch muscle development
Provedor de dados: 20
Autores: Rabah, S.
Study of microscopic structural changes of red and white muscle of coho salmon, Oncorhynchus kisutch, through different developmental stages and through transition from parr to smolt revealed developmental variation in fibre size where white fibres were larger than red ones. The increase in fibre area, characterizing all stages of development, was associated with reduction in both fibre and capillary densities. In large fish the reduction in red muscle capillary density was 10 fold lesser than that of white muscle.

Low genetic variability in the fifth introduction  of Litopenaeus vannamei in Cuba, as estimated  with microsatellite markers
Provedor de dados: 20
Autores: Artiles, A.; Rodríguez, I.; Pérez, A.; Pérez, L.; Espinosa, G.
The present work estimated the genetic variability and relatedness index of the fifth stock of Pacific white shrimp,  Litopenaeus vannamei, imported into Cuba for farming purposes from the US Shrimp Improvement System (SIS). Ge- netic variability was estimated by genotyping 33 samples for four microsatellite loci: M1, Pvan 1815, Pvan 0040 and  Pvan 1758. This stock had average expected and observed heterozygosities of 0.37 and 0.27 respectively; the lowest  of all stocks previously introduced in Cuba. The above, together with the low amount of allelic variants detected for  each microsatellite, was suggestive of low genetic variability. In addition, pairwise relatedness coefficients clustered  around unity, indicating a high degree of consanguinity. Taken...

Some Aspects of Sea Cucumber, Holothuria scabra (Jaeger, 1935), along the Coast of Dar es Salaam
Provedor de dados: 20
Autores: Kithakeni, T.; Ndaro, S.G.M.
Some aspects of the biology of the sea cucumber Holothuria scabra Jaeger, 1935 were studied along the coast of Dar es Salaam. Samples of Holothuria scabra were collected from Kunduchi and Buyuni between January and December 1999. The abundance of Holothuria scabra was higher in Buyuni (3951) than in Kunduchi (1176). However, the level of exploitation per year from far reefs was higher in Kunduchi than in Buyuni. Sea cucumber harvesting by villagers is done monthly on intertidal areas and from reef flats near to the villages. Higher catches from Buyuni were recorded during August and November (perhaps due to light winds such that trips could be made to far-off reefs), while the catch from Kunduchi was relatively low throughout a year. The length- frequency...

The number of purse seiners active in the Western Indian Ocean increased to 51 during the last quarter of 1989, to peak at 52 vessels in November, this being the highest number of vessels recorded in this fishery so far.  During the same period last year the number of vessels in operation increased from 43 in October to 48 at the end of the year. The overall fishing performance of the fleet throughout the year is comparable to that obtained in previous years.  The fishing results however were not as good as that obtained during 1988.  Daily catch rates averaged 18.6 MT, compared to 22 MT in 1988 and 17.9 MT in 1987.  Skipjack was the predominant species caught, comprising 67% of the catch with a corresponding marked decrease in the proportion of yellow fin...

Abundancia y distribucion de huevos y larvas de la merluza argentina (Merluccius hubbsi Marini, 1933) en un area de desove intensivo en el litoral norpatagonico.
Provedor de dados: 20
Autores: Bellizia, L.L.; Pan, J.; Venerus, L.A.
Argentine hake Merluccius hubbsi represents nowadays the main fishery resource of the Argentine Sea, in spite of the fact that the percentage of captures related to total fishery production has fallen down 30% in the last decade. The abundance and distribution of hake eggs and larvae in an intense spawning area in front of Isla Escondida (Chubut province), are analyzed. This phenomena was studied from a comparative-historical point of view allowing to apppreciate the evolution of a resource at present undergoing an overfishing pressure, capable of pushing it to collapse. Since 1973 maximum egg densities diminished and, if total egg production is considered a reliable index for recruitment prediction, no signs of overcoming stocks can be seen. On the other...

The eastern African coastal forest ecoregion is recognised as one of Africa’s centres of species endemism, and is distributed over six countries (Somalia, Kenya, Tanzania, Mozambique, Zimbabwe and Malawi). Most is found in Kenya, Tanzania and Mozambique, which form our focal region. The coastal forests are fragmented, small and surrounded by poor communities that have a high demand for land and forest resources. Although coastal forests have significant cultural and traditional values for local communities, they do not receive adequate support from the relevant government authorities and international conservation institutions.

In 2000, the National Research Council (NRC), an arm of the National Academy of Sciences, released a report entitled, "Toxicological Effects of Methylmercury." The overall conclusion of that report was that, at levels of exposure in some fish- and marine mammal-consuming communities (including those in the Faroe Islands and New Zealand), subtle but significant adverse effects on neuropsychological development were occurring as a result of in utero exposure. Since the release of that report, there has been continuing discussion of the public health relevance of current levels of exposure to Methylmercury. Much of this discussion has been linked to the release of the most recent longitudinal update of the Seychelles Island study. It has recently been posited...

Los datos fueron obtenidos con un sensor de presion instalado en el veril de 9 m. en Bahía Naufragio, obteniéndose un registro de 2436 datos de alturas significativas y períodos medios. Del análisis de las series de alturas, períodos y los vientos de la región se determinó que las olas registradas corresponden a un régimen estacional ya que las de mayor altura y menores períodos se presentaron durante la época seca (de Mayo a Septiembre), con la intensificación de los vientos del sur y sureste, y las de menor amplitud y grandes períodos en la época húmeda. El arrecife de Schiavoni que se...

The industrial tuna fishing activity in the Western Indian Ocean, Report for the year 2000: Impact on the economy of Seychelles
Provedor de dados: 20
Autores: Marguerite, M.A.
Fishing has traditionally played an important role in the socio-economic development of the country providing an important source of exports and foreign exchange earnings, job creation, government revenue and most of all an important source of animal protein for the population. With the emergence of Port Victoria as a major tuna landing and transshipment center in the region coupled with the country's venture in tuna canning activity, the importance of the fisheries sector has grown even further to establish itself as a major source of foreign exchange earnings and contributor to the country's wealth generation.

The Case of South Africa
Provedor de dados: 20
Autores: Wynberg, R.; Grundy, I.
South Africa is in general a dry country, where the vegetation cover is determined by its low mean annual rainfall. As a result most of the country is covered by dry savanna woodland or woodland scrub. Midgley et al (1997) define forests as being closed-canopy plant communities comprising mainly woody plants more than 5m tall and maintain that within this definition patches of forest occur within almost all southern African biomes. Most natural evergreen forests are found in areas of higher rainfall, however, in a narrow broken belt along the southern and eastern seaboard, and in the country’s mountainous regions towards the eastern borders with Swaziland and Mozambique (Figure1) (Low and Rebelo, 1996). Estimates of the area covered by closed canopy...

Se ensayó la fermentación para concentrados con cultivo de Bioyogurt, utilizando NaOH y CaCO3  como neutralizantes de la acidez, y se observó su efecto sobre la población final y la viabilidad. La fermentación se realizó en un medio semi- sintético. La solución de NaOH 4N se adicionó automáticamente durante el proceso para mantener el pH = 6,20 y el CaCO3  en polvo, se adicionó en porciones, según la variación de la acidez. Con ambas alternativas se obtuvo una población total final entre 1014  y 1016  UFC/mL, favorable para el proceso de preparación de concentrados bacterianos. Desde el punto de vista práctico, el uso del CaCO3  sólido presentó dificultades de manipulación y mayor riesgo de contaminación que el NaOH.

Autores: Santa Cruz, L.; Castro, D.; Sardiñas, O.
Como parte del proyecto de implementación de la dieta macrobiótica en Cuba se valoró la situación de una arcilla italiana, empleada para enriquecer al agua potable con sales minerales, por una cubana similar (bentonita natural de Managua tipo 1). La caracterización minerológica, química y granulométrica de ambas arcillas fue similar. Se estudió el efecto de tres concentraciones de arcilla cubana en agua potable (0,1; 0,5 y 1 %) después de 24 h. Este tratamiento incrementó significativamente las concentraciones de sodio, magnesio y hierro y disminuyó las de calcio, cinc y cobre en el agua; todos los elementos cumplieron con las normas vigentes de agua potable.

Autores: Masmoudi, W.; Romdhane, M.S.; Kheriji, S.; El Cafsi, M.
Pendant la saison printanière de recrutement maximale (avril/mai2000) des alevins de Liza ramada , nous avons effectué 4 campagnes de  pêche au niveau de l’embouchure de canal « Khélij ». Les alevins de cette espèce  ainsi collectés ont été  repartis en trois classes de taille (classe I :19,4  1,3 mm ; classe II : 45,5  5,3 mm et classe III : 63,2  6,3mm)  dans le but d’y analyser les résidus du  lindane (  HCH ), un pesticide organochloré. Nos résultats ont révélé des concentrations de ce résidu chutant de 57,42  12,49 à 12,67  3,27  ng/ g de graisse en passant de la classe I à la classe III. Cette diminution est probablement due à une amélioration avec l’âge des capacités métaboliques de l’espèce vis à vis du contaminant. D’un autre côté, Liza...

Polycyclic aromatic hydrocarbons and aromatic plasticiser materials in the sea water of alexandria coastal area
Provedor de dados: 20
Autores: Emara, H.I.; El-Deeb, M.K.Z.
Polycyclic aromatic hydrocarbons (PAHs), the real contaminants of petroleum, were detected in the surface seawater of Alexandria coastal area in winter and spring seasons of 1995. Their order of predominance, particularly for the individual components were principally due to the processes of input, transport and fluxes. Variation of PAHs was not following seasonal changes but it was slightly affected by partial dissolution of the lowerboiling aromatic hydrocarbons. The most abundant component of aromatic hydrocarbons was pyrene (PAH),112ngI-1 followed by naphthalene(56ngI-1) and its alkylated derivatives (dicyclic), then phenanthrene(14ngI-1) and its methylated derivatives (tricyclic). The potential fish carcinogenic PAH, dibenz [a &amp; c] anthracene was...

Geological disasters on the superficial seafloor were revealed in geological investigation on the Yellow River subaqueous delta. Combined with dynamic triaxial tests and wave flume experiments, occurring conditions and forming patterns of liquefaction as well as motion of the liquefied soil were explained in this paper. Based on the viewpoint that the geological disasters were formed due to silty soil liquefaction under storm waves, re-stratification issue of the superficial stratum was analyzed. Movement of the liquefied soil agreed with the wave, leading to differentiation of the soil particles. Research issues in respect of geological, environment and engineering of storm-induced liquefaction were also discussed.

Knowledge of the life history of fish larvae is of practical importance to understand variations in the survival rate not only for cultivated fish but also for fishery biology studies. With the aim of recognizing critical changes during the first days of life of red porgy larvae, the oxygen consumption, growth, and food utilization were studied. After hatching, the larvae were transferred to two 400 L fiberglass tanks with microalgae (Nannochloropsis oculata)and enriched rotifers (Brachionus plicatilis)as initial food. During the incubation and larval rearing, water temperature was kept at 18.0 ± 0.5ºC and salinity ranged from 33.0 to 34.0 psu. Results indicate a decrease in larval growth between day 3 and 4 after hatching, when larvae opened their mouths,...

ABSTRACT Temporal variability in the population parameters of the Caribbean spiny lobster Panulirus argus (Latreille, 1804) in Cuban waters Modifications in life-history traits are often concomitant with prolonged periods of exploitation or changes in the environment, producing changes in population abundance. . Both of them act as selective forces and could affect population parameters behaviour like growth rate, reproduction output, natural mortality rate and size at first maturity. Because of the economic importance of Caribbean spiny lobster (Panulirus argus) for Cuba and other countries of western central Atlantic, it is necessary to make a careful study in its life cycle processes and changes happened in temporal scale. Data used were obtained from...

Autores: Poisson, F.; René, F.; Guyomard, D.
The Réunion fishery has experienced rapid growth and development in all segments (artisan fishery, Antarctic deep sea fishery, longline fishery) for the last five years, in marked contrast to the situation experienced by the huge majority of other European Union fishing communities. The longlining sector, which began five years ago, has shown the most rapid of development. Longlining has, since 1996, not only equalled but overtaken the artisan fishery, with more than 2,300 t production in 1997 and an active fleet of 21 vessels which range from 9 to 33 m long. This fishery targets swordfish (Xiphias gladius) mainly throughout the year, from the equator to 32oS, using deep freeze conservation techniques. The artisanal segment has also shown a rapid extension...

Fishing activities with trawl nets used by the commercial fleet in the continental slope of the Southwest Atlantic are quite different from those developed in the Argentine shelf because, in the former, depths are very variable and slopes are more marked: therefore, fishing procedures are quite different. In this work, the most important differences are described: fish species, fishing gear, type of vessel and machinery on deck, as well as the training and experience of skippers.

The assessment covers hake between 34° and 48°S (Argentina and Uruguay), excluding Golfo San Matías. Total international landings and Argentine catch-at-age and effort data available for the 1983-1991 period allowed an analytical assessment. Tunning of the VPA was made using Laurec-Shepherd analysis and Extended Survivor analysis. The results of these analysis are congruent with the information about the state of the stock. VPA biomass estimates are aound 2.1 and 2.7 mill. Tonnes, which are similar to those calculated through surveys. The Spawning Stock Biomass estimated for 1991 is considered to be within limits where the stock shows stable recruitment.

The first meeting of the SGXML resulted in the initial development of a plan to guide an investigation into how XML technology might best be used in an oceanographic context. From an IOC/IODE perspective, the requirement was to design a framework for an XML structure that data centres can use. It is thought that a mutually acceptable structure will solve many problems. A series of short presentations were given to illustrate XML developments in the various organizations represented. These presentations, predominantly served to initiate a series of discussions. The main requirements for an XML based exchange system involved the development of a document type definition (DTD) and standardised syntax for common content (code tables). With these, it should be...

Autores: Pepperell, J.C.
Tagging of fish by fishery participants, both recreational and commercial, is a popular activity. It gives the fisher a sense of participation in a scientific activity which will add to knowledge about their target species. The best known examples of this activity are so-called cooperative tagging programs through which recreational anglers (and sometimes, commercial operators) tag and release fish as part of a broad scale, long term undertaking. There are many such programs in operation around the world, some of which are very large, and have been in operation for several decades....

The IOC Data and Information system will provide seamless access to the real-time and delay-mode oceanographic data and services across all IOC and related programmes, handling data from the point of collection, through processing and quality control, to archival and dissemination. The IODE developed Ocean Data Portal (ODP) will facilitate the exchange and dissemination of data and services from these systems and will be a key component to deliver the objectives of the IOC Data and Information Strategy. Data, metadata and information will be fully interoperable with the WMO Information System (WIS) and the ODP will function as a WIS Data Collection or Production Centre (DCPC) providing oceanographic data and services.

Autores: Mercado Leal, S.I.
El embalse Rapel, es un cuerpo de agua que está siendo sometido a un fuerte impacto antropogénico, por lo que evidencia severos signos de eutrofización. Esto último debido a que el embalse se ha transformado en el cuerpo receptor de una gran diversidad de efluentes (industriales, agrícolas y domésticos), que evacuan sus descargas sin ningún tipo de tratamiento. A lo cual se le debe agregar la recepción de aguas provenientes de los relaves de la mina de cobre “El Teniente”. Con el objetivo de determinar la presencia y acumulación de metales pesados en el agua y en los organismos zooplanctónicos, durante el mes de Octubre del 2003 se tomaron muestras de agua y de ejemplares de Ceriodaphnia dubia, Bosmina chilensis y Diaptomus diabolicus.

The IODE Quality Management Framework (IODE-QMF) provides overall strategy, advice and guidance for NODCs to design and implement quality management systems (QMS) for the successful delivery of oceanographic and related data, products and services. The IODE Committee encourages NODCs to implement a QMS but does not propose a specific standard. NODCs may seek ISO 9001 quality management certification, however this is not mandatory and NODCs can successfully implement an effective quality management system without going through formal ISO 9001 certification.

The Joint WMO/IOC Technical Commission for Oceanography and Marine Meteorology (JCOMM) was formally established in 1999 by Thirteenth Congress and the Twentieth Session of the IOC Assembly, through a merger of the Commission for Marine Meteorology (CMM) and the Joint IOC/WMO Committee for IGOSS. JCOMM is the reporting and coordinating mechanism for all operational marine activities in both WMO and IOC. As such, it is charged with the international coordination, regulation and management of an integrated, operational, oceanographic observing, data management and services system which will eventually become the ocean equivalent of the World Weather Watch. Thus JCOMM is the implementation arm of GOOS.

Influence of barley straw and submerged macrophytes on fishpond wastewater quality
Provedor de dados: 20
Autores: Ghobrial, M.G.; Okbah, M.A.; Gharib, S.M.; Soliman, A.M.
Barley straw has received, recently, considerable attention as an algicide, which could be used to control algal growth in fishponds. It is regarded as cost-effective, user friendly and environmentally sounds. On the other hand, the submerged wetland macrophytes are crucial for the stabilization of clear water state in shallow lakes, by their active production of anti-algal compounds (allelochemicals) through allelopathy. Microcosm experiments using barley straw and the submerged macrophytes: Najas marina L., Potamogeton pectinatus L. and Ceratophyllum demersum L. in culture media with fishpond water were carried out outdoors to simulate the situation as natural as possible. Nutrients concentrations were measured beside the analysis of phytoplankton and...

Abstract: An analysis of sea level synoptic variations in the Gulf of Batabanó is carried out starting from data of direct measurements. Spectral analysis is applied. It is corroborated with new elements the prevalence of meteorological variations in part of the southwestern shelf, and the spectral structure of this shelf is characterized. The influence of meteorological factors is evaluated. It is demonstrated the influence exerted by the southern component of the wind on this variations. There are signs of the possible influence of ENSO on sea level monthly variability at La Coloma; and there is a great similarity between this variability and that of Siboney.

Autores: Odido, Mika.
The utilization of available data and information for management and exploitation of the marine environment and resources is one of the major challenges facing African coastal states. The success of development strategies will depend to a great extent on the availability and use of scientific and technical information in a form that can be readily understood and applied. Though several programmes initiated at the national, regional and global level have generated tremendous amounts of data and information, these have not been effectively used for national development. This has mainly been due to limited access to data collected in the framework of these programmes, and the lack of skills for analysis and interpretation of the data. There is a need to...

Wetlands are dynamic landforms which vary in both time and space. Tanzania's wetlands areclassified according to the physiography and the environment in which they exist. Coastalwetlands, Rift System wetlands and the wetlands of highland drainage basins are the majorgroups. Coastal wetlands are formed by wave action and tidal influence; beaches and lagoons exist because of wave action; mudflats, marshes, mangrove swamps, estuaries and deltas aretidal in origin. Rift System wetlands occur in the rift depressions and are characterised by salt lakes, playas, swamps and short streams with inland drainage. The highlands are drained by long rivers originating in the inland catchments and ending in oceans or lake basins. On theway to their outlets, they form...

Différents aspects de la biologie de la sardinelle plate Sardinella aurita (Valenciennes, 1847) sont étudiés : sex-ratio, stades sexuels, taille de première maturité sexuelle et relation taille – poids. Les résultats obtenus montrent que le sex-ratio est significativement en faveur des femelles et varie également avec la taille. Ils mettent également en évidence que la période de ponte s’étale de juin à septembre et que la taille de première maturité sexuelle se situe entre 28 et 29 cm. D’autre part, la relation taille – poids indique une allométrie légèrement majorante aussi bien chez les mâles que chez les femelles.

Seychelles tuna bulletin : first quarter 1991
Provedor de dados: 20
The number of purse seiners vessels active in the Western Indian Ocean remained constant at 43 from January to March.  This represents a significant drop from last year 1st quarter average of 52 vessels. To date the fishing results appear to be better than those of the same period in 1990 with the catch rates being substantially higher.  Yellowing tuna made up 88% of the catch in January and February dropping down to 67% in March which is the expected trend during this time of the year.  The fishing pattern also followed a similar trend to previous years in that most vessels were active to the East of the Seychelles EEZ and moving South towards the Mozambique Channel in March.The total catch for purse seiners fishing in the Western Indian Ocean for 1990...

Historia de vida y dinámica de poblaciones de Lychnorhiza lucerna (Scyphozoa) ¿Un recurso pesquero alternativo?
Provedor de dados: 20
Autores: Schiariti, A.
In this Thesis we presented the first steps in the study of the life history and population dynamics of Lychnorhiza lucerna as well as the possibilities of development of its fishery in Argentina. L. lucerna presented a metagenetic life cycle characteristic of most scyphozoans. Polyps reproduced asexually by the production of podocysts and polidisk strobilation. The combination of both types of asexual reproduction resulted in a high strobilation rates indicating that the abundance of medusae would strongly depend on polyps abundance and reproduction. The absence of ephyrae in the Río de la Plata estuary suggest that L. lucerna doest not complete its life cycle locally but medusae would be produced by polyps located northwards along the Uruguayan or...

Las masas de agua encontradas a partir de las variables de estado, indican una contribución muy pobre de Agua Subtropical Superficial (ASTS), mientras que las mayores contribuciones fueron de Agua Tropical Superficial (ATS). Parámetros como la temperatura y la salinidad determinaron un calentamiento del océano, tanto a nivel superficial como subsuperficial, lo cual sería una consecuencia de los procesos de redistribución de calor del océano.Esta dinámica ocasionaría anomalías del orden de los 30 metros para el caso de la profundidad de la termoclima y 2°C para el caso de la TSM. En el plancton se registraron valores mayores a 5000 larvas de peces/10 m2. La menor cantidad (260 larvas/10 m2) se registró hacia el norte del Golfo, observándose al mismo tiempo...

Autores: Pouliquen, S.; Diggs, S.; Roemmich, D.; Gould, J.; Desaubies, Y.
Argo is the most visible and innovative new element of the sustained observing system for the open ocean. Since mid-2004 it has become the most abundant source of profile data from the ocean and that abundance will continue to increase as the array grows to its target of 3000 floats that will deliver 100,000 CTD profiles per year by 2007. Paradoxically, the existence of Argo has highlighted the importance of research ship-based CTD observations. Argo floats are expendable, consequently there is no opportunity to do laboratory calibrations to check sensor drift. A method has been devised to estimate sensor drift by making comparisons with nearby (in space and time) CTD profiles collected by research ships and by comparing new and old floats. This method is...

La Corriente Circumpolar Antártica y su influencia en el clima
Provedor de dados: 20
Autores: Rodrigo, C.
Los océanos influencian el clima de la Tierra por el almacenamiento y transporte de grandes cantidades de calor, humedad y dióxido de carbono. El calor absorbido por los océanos en un lugar puede ser llevado por las corrientes marinas a distancias de miles de kilómetros antes de ser liberado a la atmósfera. La liberación de calor desde los océanos a la atmósfera provoca movimientos en ésta que determinan a gran escala y lentamente los patrones de temperatura y precipitación que establecen el clima. El océano Austral se localiza desde el Frente Sub-Antártico (aproximadamente entre las latitudes 50° y 60° S) hasta la costa del continente antártico. El océano Austral es el único cuyas aguas rodean todo el globo, lo cual es un elemento crucial para el motor...

Argopecten circularis (Sowerby, 1835) fecunddity was estimated during spawnings of February-March 1989 and March-May 1990 in Bahía Concepción, Baja California sur, México. In general, the number of oocytes released during the spawning of Argopecten circularis were potentially relatad to shell height. The calculated average oocyte wet weight during the maturity period was 8.9033x10^-8 g. Spawning ocurred ¡n individuáis 44 to 77 mm in height. The highest fecundity occurred ¡n bivalves 58 to 77 mm ¡n height. Mean fecundity obtained for all heigts by regression analysis during spawning in February-march 1989 was 12, 102, 243 oocytes. In April-May of the same year, there were 17, 917, 006 oocytes, and during March-May 1990, 16, 938, 117 oocytes.

Data used to generate the tables and figures presented here are based on daily catch and effort forms (logbooks) returned from fishing vessels that are licensed to fish in the Seychelles EEZ and for purse seiners, as well as from data collected via the tuna sampling programme conducted during transshipment in Port Victoria. Sometimes there are delays in these being received at SFA, especially for longliners that often spend up to a year at sea, and for purse seiners the delays are usually during and just after the second quarter of the year when most vessels are fishing in the Mozambique Channel and are not necessarily using Port Victoria for transshipment.

Análisis de cambios en los afloramientos en el Pacífico ecuatorial este, durante eventos El Niño Oscilación del Sur

Autores: Perugachi Salamea, C.
The ocean reanalysis Simple Ocean Data Assimilation (SODA) 2.2.4 is used to explore the changes in upwelling from normal conditions to either El Niño or La Niña conditions. Physical and thermodynamic variables from the reanalysis are used to explore the structure and behaviour of El Niño Southern Oscillation (ENSO) events. The results of this analysis show that sea surface temperature (SST), entrainment velocity, wind stress, mixed layer depth, wind stress curl, and heat content anomalies are in general agreement with ENSO theory. Interestingly, the distribution of upwelling based on the entrainment velocity is very patchy, which led us to explore zonal and meridional sections of vertical velocity. We used three methods to compute changes in upwelling...

The Benguela Current ecosystem is situated along the coast of south western Africa, stretching from east of the Cape of Good Hope, in the south, northwards into Angola waters and encompassing the full extent of Namibia’s marine environment. It is one of the four major coastal upwelling ecosystems of the world which lie at the eastern boundaries of the oceans. Like the Humboldt, California and Canary systems, the Benguela is an important centre of marine biodiversity and marine food production. Its distinctive bathymetry, hydrography, chemistry and trophodynamics combine to make it one of the most productive ocean areas in the world, with a mean annual primary productivity of 1.25 kilograms of carbon per square metre per year—about six times higher than the...

Fission in the Zoantharia Palythoa caribaeorum (Duchassaing and Michelotii, 1860) populations: a latitudinal comparison
Provedor de dados: 20
Autores: Acosta, A.; González, A.M.
There are few regional studies attempting to compare the asexual reproductive output of marine populations, particularly when they are exposed to different environmental conditions. In this study we compared Caribbean and Southwestern Atlantic Palythoa caribaeorum populations in terms of ramet production, the minimum colony size for fission, and the relationship between fission frequency and colony size. Fission process was quantified in Ponta Recife and Praia Portinho, Sao Paulo, Brazil, and in Punta de Betín, Colombia, during the summer (December-January) of 1997 and 1998, respectively. Fission started at small colony size in both populations studied (&gt; 4 cm2). The number of ramets produced per colony increased with colony size in Brazil and Colombia....

St Lucia – Africa’s Largest Coastal Lagoon - Quaternary history and effects of global change: Papers 1-3
Provedor de dados: 20
Autores: Haldorsen, S.; Cuamba, F.; Mugabe, J.; Været, L.; Stabell, B.; Taylor, R.
St Lucia, is a large coastal lagoon, which is very sensitive to changes in water level,volume and quantities of inflowing freshwater. It is therefore sensitive to the effects of global change that alter sea levels and rainfall. Earlier studies have shown that, during the Eemian, St Lucia was a marine environment. At that time global sea level was 3-4 m higher than that at the present. During the falling sea level leading up to the Last Glacial Maximum, St Lucia was above sea level and the climate was mainly dry. Studies of cores at Brodie’s Crossing showed that there were episodes with a wet climate at 23 000 years BP. During this period peat was deposited. Overlying this is wind-blown sand. Diatom studies indicate that this overlying sand was mainly...

Tropical forest ecosystems have multiple functions and therefore are great significance for the well-being of people. It is widely acknowledged that forests and trees simultaneously provide a wide range of socio-economic and environmental benefits and values to humankind. They deserve conservation and wise use for the benefit of rural people who are dependent on these forests and for the benefit of humanity in general. Unfortunately, the use of tropical forests has been undertaken with little care about their potential to fulfil many functions and also about their future.

Le chinchard à queue jaune est un Carangidae qui fait l’objet d’une exploitation par les différents types de pêche le long des côtes tunisiennes. Dans le présent travail on se propose d’étudier l’âge et la croissance sur la base de la distribution des fréquences de taille dans la région Nord de la Tunisie. La décomposition de ces fréquences de taille est réalisée suivant la méthode de Battacharya (1967). Deux périodes sont considérées, la première correspond à l’année 1998 et la seconde s’étale entre Novembre -1999 et Décembre -2000. Pour la première période, 6 classes d’âges ont pu être identifiées alors que pour la seconde cette valeur est de 7. Les équations de croissance linéaire annuelle suivant le modèle Von Bertalanffy (1938) ont été établies.

Foraminíferos bentónicos de Salinas, Ecuador y su relación con el medio
Provedor de dados: 20
Autores: Gualancañay, E.
Salinas por su posición en la península de Santa Elena está situada en el límite noroeste del Golfo de Guayaquil y, debido a que la línea costanera se curva hacia el noroeste y se coloca por ello fuera de la acción de la corriente de Humboldt, aumenta progresivamente la precipitación hacia el norte (PMRC, 1995). Se realiza el estudio de las especies de foraminíferos bentónicos del área de Salinas y se hace la relación de las especies más frecuentes: Elphidium articulatum, f, typica; reophax cf. guttiferus; Rotalia cubensis y Textularia secasensis con los factores ambientales: salinidad, temperatura, pH, oxígeno, profundidad, turbidez, alimentación y sustrato.

Comparative study on octopus vulgaris (cuvier, 1797) from the mediterranean and red sea coasts of egypt
Provedor de dados: 20
Autores: Riad, R.; Gabr, H.R.
Specimens from common octopus, Octopus vulgaris captured from the Red Sea and Mediterranean Sea showed significant differences in four of seven morphometric measurements .These differences are sufficient to recognize the populations of this species in the two habitats. The computed length-Wight relationship and condition factor for common octopus in both areas showed that representatives of this species from the Red Sea are heavier than those captured from the Mediterranean Sea for the same length group. Moreover, the natural mortality coefficient of Mediterranean representatives was comparatively higher than for the Red Sea octopus. This shows that the environmental conditions in the Red Sea are more suitable for O. vulgaris than in the Mediterranean Sea.

Integrating Anthropogenic and Climatic Factors in the Assessment of the  Caribbean Spiny Lobster (Panulirus argus) in Cuba: Implications for  Fishery Management
Provedor de dados: 20
Autores: Puga, R.; Piñeiro, R.; Alzugaray, R.; Cobas, L. S.; de León, M. E.; Morales, O.
The Caribbean spiny lobster Panulirus argus, the most valuable Cuban fishery resource, is managed with a set of input  and biological controls. The aim of this study was to integrate  two indices that relates water and nutrients supply and tropical  cyclones activity in the stock assessment, through simultaneous estimation of the parameters of a spawning stock–recruitment  function in a statistical catch-at-age analysis. The population dynamics model allowed estimating key Reference Points for  management at fixed levels of  fishing mortality rate and environmental conditions. The results indicated that the reduction of  recruitment and catches in the Cuban spiny lobster fishery could be a result of synergistic cumulative effects because of the...

Artisanal fishing boats in Seychelles
Provedor de dados: 20
Autores: Payet, R.J.
The results of a census of fishing boats on Mahe, Praslin and La Digue are presented. In total 437 boats were counted of which 278 were outboards with engine, 48 were open whaler, 35 were pirogues, 25 were lekonomi, 22 were schooners, 11 were semi-industrial so were lavenir, 12 were 'others', 8 were whaler with deck, 4 were nouvo lavenir and 3 were wooden boats without engines. The details are discussed to understand the characteristics of the artisanal fishing boats. An analysis of the historical data follows. The number of pirogues and schooners decreased from 1985 to 1995, whilst the numbers of whalers have increased. Outboards on the other hand had remained relatively stable. The changes in the number of boats are a result of interaction between the...

Situation de la Pêche en Côte D’Ivoire
Provedor de dados: 20
Autores: Dadi, S.G.
En Côte d’Ivoire, le secteur halieutique tient une place de choix dans le domaine économique, social et nutritionnel. Le poisson est la première source de protéine animale et sa consommation est de 15 kgs/hab/an. Malgré la faiblesse de la production nationale qui est généralement comprise entre 70 et 100 000 tonnes par an et l’importation de plus de 228 000 tonnes de poisson en 1997, la balance commerciale reste excédentaire de plus de 17 milliards grâce aux exportations de conserves de thon. La pêche constitue cependant un secteur pourvoyeur d’emplois avec environ 70 000 emplois directs et 400 000 emplois indirects. Elle génère près de 48,08 milliards au PIB et compte donc pour 0,80% dans la création de la richesse nationale.

Economics without markets: Policy inferences from nature-based tourism studies in Namibia
Provedor de dados: 20
Autores: Humavindu, M.N.
This work documents policy inferences from valuation studies carried on nature-based tourism in Namibia. It is found that nature-based tourism in Namibia is not optimally priced and that significant resource rents do exists. Thus efforts are needed to ensure that Namibia’s natural assets are priced optimally and that the resource rents are captured. In capturing the resource rents, a combination of methods (user fees, indirect taxation schemes and environmental voluntary funds) should be pursued. Pricing policies adopted should at best reflect the costs of providing the environmental good/service.

Autores: Sorinmade, S.O.; Talabi, S.O.; Banwo, A.
A preliminary investigation was conducted with freshly caught West African long croaker (Pseudotolithus typus).  Half of the fish stored at ambient temperature (28 - 32oC) for 5, 12, 13, 24 and 36 hours were gutted.  These conditions enable a high rate of fish deterioration and spoilage; thus facilitating the elaboration of characteristics which would subsequently be used to establish some sensory guidelines for fish quality evaluation in Nigeria. Several sensory deteriorative changes were observed whose application for sensory assessment may be time consuming and confusing to Fish Quality Inspectors.  Hence, it is concluded from this study that the most important sensory quality indices which can be used as guidelines for the Nigerian Fishing Industry and...

La pesca y utilización del tiburón en el Ecuador
Provedor de dados: 20
Autores: Bostock, T.; Herdson, D.
Los tiburones son muy abundantes en las aguas ecuatorianas. Son capturados tanto por embarcaciones artesanales como por barcos industriales junto con peces pelágicos grandes (dorado, picudo, atún) y como pesca acompañante en los arrastreros. No existe una pesquería dedicada específicamente a la captura del tiburón. Sin embargo, se capturan grandes cantidades como parte de la pesca acompañante de varias otras pesquerías. Los tiburones más comunes en las capturas son los de la familia Carcharhinidae, los carcharhinidos. Se tiene que considerar que no todos los tiburones capturados se comercializan. A más de la captura de la flota artesanal, una porción muy apreciable del total es realizada por barcos industriales, los atuneros y los palangreros, éstos...

Aspectos teóricos sobre ondas internas
Provedor de dados: 20
Autores: Chiriguaya, J.
Las ondas internas son movimientos ondulatorios en fluidos de estratificación estable, en los cuales la máxima amplitud del movimiento vertical tiene lugar en la zona por debajo de la interfase, la cual se encuentra entre las superficies del fluido. La principal fuerza de recuperación es la gravedad. Se cree que las ondas internas se generan en el mar por variaciones de la presión atmosférica y por influencia de ondas superficiales de baja frecuencia en aguas de profundidad variable. Las ondas internas pueden presentarse entre capas de diferentes densidades en el océano, porque la diferencia de densidades conlleva a una presión gravitacional o hidrostática que será una fuerza restuaradora si el fluido se desplaza verticalmente.

Mozambique is situated on the east coast of Africa between 10°27´S and 26°52´S latitude and has a coastline of 2,780 Km, which can be divided into three regions: The Northern region (characterised by the occurrence of corals and rocks); the Central region (sandy) and the Southern region (composed of dunes). Partly, this division determines the distribution and the potential of the marine ecosystems, their access and also influence the choice of fishing methods and equipment. In Mozambique, fishing is a highly ranked activity not only for the absorption of the local labour force but also for the provision of aquatic protein products to the local populations and earning hard currency for the country. The main marine resources are crustaceans (mainly prawn,...

Autores: Blé, M.C.; Otchoumou, K.A.; Alla, Y.L.; Kaushik, S.J.
Une grande variété de produits et sous produits végétaux méritent d'être valorisés en alimentation des poissons d'élevage en milieu tropical. Les rendements observés pour chacune des espèces étudiées montrent les possibilités d'utilisation des protéines végétales en substitution à celles de la farine de poisson. En plus, ces potentialités sont accrues par la possibilité d'élimination des facteurs antinutritionnels présents dans les matières végétales.

Autores: Igbinosun, J.E.; Talabi, S.O.; Roberts, O.O.; Okolie, E.
The nutritional effects of the complete or partial replacement of fishmeal by Soyabean meal in the diets of catfish were investigated.  Four diets A, B, C, and D in which 34% of fish meal was replaced weight by weight with 0%, 10%, 20% and 34% of Soya-bean meal respectively were fed to four groups of brackish water catfish for six weeks.  Results showed that although the digestibilities of proteins were almost equal in all the four groups, the groups fed diet D in which 100% of the fishmeal had been replaced by Soyabean had the least growth as compared to A, B and C.  Nevertheless, the group fed diet D (with the least growth) had an economy of gain twice that of the group fed diet A.  The liver and heart indices and the proximate compositions of the muscle...

En este trabajo se presentan los resultados de los análisis térmico-diferenciales para la identificación de minerales de arcillas en el Archipiélago de Jambelí. La distribución de los minerales de arcilla refleja el área de influencia de los principales ríos que drenan áreas de diferente composición mineralógica. Las illitas están distribuídas en todo el Archipiélago. Las smectitas son abundantes en las zonas periféricas. Las cloritas están restringidas a las desembocaduras de los ríos que drenan terrenos metamórficos. La identificación de estos grupos mineralógicos coincide con la de otros estudios de otros autores que han utilizado difractometría de rayos X.

Regional report « coral reef monitoring » - South West Indian Ocean Region – 2003 Annual Report
Provedor de dados: 20
Autores: Koonjul, M.; Meunier, S.; Moyne-Picard, M.; Bigot, L.; Tara, L.; Jean, M.; Bijoux, J.; Ahamada, S.
The coral reefs of the Indian Ocean are characterized by a high degree of endemic organisms and biodiversity. Over and above their global importance, they are revenue sources for the coastal and insular populations, and play an important role in coastal protection, in an area that is subjected to strong cyclonic activity. Coral reefs are present in the five member states of the IOC. They constitute a federative theme for the region, which justifies the need to develop a “reef monitoring action” through a “regional reef-monitoring network”. It was made clear during recent regional meetings that the reefs are subjected to very strong pressure due to human activities and natural factors (El Niño, massive coral mortality of 1998), and that their conservation...

The distribution of eight heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb nd Zn) were detected in muscles, gills, livers and bones of five fish species namely, Sargus sargus, Siganus rivulatus, Mugil cephalus, Caranx crysos and Scomberomorus commerson collected from El-Mex Bay, Alexandria during January 2003. Iron and zinc were most abundant in all fish tissues under investigation. Iron, zinc and copper recorded highest concentration levels in liver while cadmium, cromium and lead recorded their highest values in gills and bones. Provisional Tolerable Weekly Intake (PTWI) demonstrated that the concentration of metals (Cd, Cu, and Pb) in muscles of the five fishes are lower than the PTWI values, and accordingly there is no risk yet for human consumption of flesh...

Autores: Wilkinson, C.P.
There has been significant bleaching of hard and soft corals in widely separate parts of the world from mid-1997 to the last months of 1998. Much of this bleaching coincided with a large El Nino event, immediately switching over to a strong La Nina. Some of the reports by experienced observers are of unprecedented bleaching in places as widespread as (from west to east) the Middle East, East Africa, the Indian Ocean, South, Southeast and East Asia, far West and far East Pacific, the Caribbean and Atlantic Ocean.

Introduction of Fish Aggregating Devices in the Southwest Indian Ocean (A Case Study)
Provedor de dados: 20
Autores: Venkatasami, A.
During the past decades, several countries of the Southwest Indian Ocean region have attempted setting Fish Aggregating Devices (FADs) with varying success. Initially, FADs were rapidly lost without being able to produce any results. The gradual improvement in design through the work carried out mainly by SWIOP1 in the region, lead to the development of long lived FADs in Mauritius. The transfer of that technology to other islands such as Reunion, Madagascar, Comores and Rodrigues (Mauritius) gave a new impulse to the activity.

Provedor de dados: 20
Autores: Jacques, R.M.
This report reviews the lobster catch during the months of November and December 1992. In total, 38 fishing units were licenced: 26 on Mahe, 7 on La Digue and 5 on Praslin.  8 licence holders provided no information and claimed that they undertook no fishing trips at all.  Of the remainder, each fishing unit comprised an average of 3 men. 2 fishing units used traps as the only catching method, 27 used snorkelling and 1 a combination of traps and snorkelling. For the two month period, an estimated catch of 4.9 tonnes of Spiny Lobster for all sites were landed; of which Mahe contributed an estimated 2.8 tonnes.  For the month of November only, a total catch of 2.7 tonnes of lobsters were estimated and for the month of December a total of 2.2 tonnes were...

IODE's Role in Managing and Exchanging Ocean Data from Coastal Zones
Provedor de dados: 20
The coastal zones in the world are exposed to continuously increasing environmental stresses: pollution, eutrophication, erosion problems which are amplified by steadily growing economic and recreational use and demographic changes. In view of the position of the coastal environment as a buffering zone and interface between land and open ocean, an effort in integrated coastal zone management is required to achieve sustainable development. Besides the possible impact of global climate change also coastal flood protection and related safety aspects are of vital importance to the coastal population, as well as for environment and economy. By their nature, coastal processes are not confined to regional or national boundaries so their solution requires an...

Autores: Lasta, C.A.
The Coastal Project developed at the INIDEP (Mar del Plata,Argentina) offers an analysis on the operative modality of coastal assessment surveys, proposing an information process useful to standardize data collection and processes of future surveys. The efficiency of the evaluation of strata used until the year 1993 was analyzed and a new stratification is proposed. The aim was to define area-strata of importance for the main coastal species, using the traditional stratification of the coastal ecosystem and the mew methodology. The reason for redefining strata is that a decrease was been detected in the number of traditional species and an increment on the biomass of non-commercial species and,associated with it, the development of new explotation areas....

Grenadiers (Pisces, Macrouridae) of the southwest Atlantic ocean: biologic and fishery aspects
Provedor de dados: 20
Autores: Giussi, A.R.; Sánchez, F.; Wohler, O.C.; Bernardele, J.C.
Several grenadier species distribute in the SW Atlantic Ocean. Macrourus carinatus and Caelorinchus fasciatus are more frequently identified in commercial catches and during research cruises. Those benthopelagic fishes, related to subantarctic waters, inhabit at depths beyond 200 m and in high seas, between 36º S-59º S. During the surveys carried out on board of Argentinean research vessels, M. carinatus was present in 4% of the trawls performed. The highest densities (&gt;17 t nm-2), obtained between 360-380 m depth, at 39º S, decreased significantly southwards. C. fasciatus was caught in 6% of the total trawls and the highest densities (15-35 t nm-2) were found at depths beyond 200 m, south of 52º S. Due to the difficulty encountered to identify them, in...

A new innovated and cheep model in building artificial reefs
Provedor de dados: 20
Autores: Mahmoud, M.A.; Ammar, M.S.A.
A novel and cheep approach for building artificial reefs was designed in such a way that sediments in an area of high sedimentation rate will be utilized in building the artificial substrate with no further sediment accumulation afterwards. The model consists of several steel cylinders which are soldered together in such a way to form a reef flat, a gentle slope and a steep slope, with two layers of narrow opening meshes (a lower plastic and an upper metallic one). Within a short periode (3 months), a substrate layer of a total of ~ 1 cm was formed between the two meshes, this layer increased to ~2 cm after 9 months. Transplants of the three species Stylophora pistillata, Echinopora gemmacea and Montipora spongiosa grow better when the attaching surface is...

People of the Kenya coast have lived off the Indian Ocean for as long as memory can go. Folklore and legend reflect a history of dependence on the sea for livelihood, including fisheries. Due to technological limitation coupled with small human populations, harvesting from the sea had little effect in the past. Fishermen relied on simple fishing gear operated either from the shore or from dug-out and small planked canoes to supply needs of their families....

Importancia de diferentes taxa de copepodos en la dieta de los adultos de anchoita (Engraulis anchoita) bonaerense durante la época reproductiva
Provedor de dados: 20
Autores: Padovani, L.
Engraulis anchoita is the most abundant and widespread ichthic species in the SW Atlantic. Two populations of the species occur in the Argentine Sea, a northern one or Bonaerense (34 degree -41 degree S)and a southern one or Patagonian (41 degree -47 degree S). The former performs an annual migratory cycle which includes the concentration in the northern area in winter, the distribution in coastal waters off Buenos Aires prov. during spring spawning period and the concentration in the shelf feeding ground in summer. In this work the feeding habits of the northern population were studied in its spring habitat. Fish samples were obtained in 16 stations from the Buenos Aires prov. shelf, during a research cruise of the INIDEP (National Institute for Fisheries...

Aplicación del método de zonación morfo-estructural para identificar nudos sismogènicos en la región costera y cadenas montañosas de los andes septentrionales del Ecuador
Provedor de dados: 20
Autores: Chunga, Kervin; Michetti, Alessando M.; Gorshkov, Alexander I.; Panza, Giuliano F.; Soloviev, Alexander; Martillo, Carlos.
Due to the lack of information in the catalogue of historic earthquakes (1951-2010) and also of potential but unmapped faults in the field, the seismic zoning modeling for Ecuador does not define parameters of equivalent attenuations of the tectonic activity of the territory. The aim of this research is to provide new engineering techniques for seismic hazard evaluation. The technique of this study is based on the assumption that strong earthquakes are associated within structural nodes that are specific structures formed around intersections of fault zones. The nodes have been delineated with a morphostructural zoning method, based on the idea that the lithosphere is made-up of different-scaled blocks, separated by mobile boundaries. These blocks are...

Spring blooms of the toxic dinoflagellate Alexandrium tamarense in the Argentine sea produce shellfish toxicity through the parallytic shellfish poison (PSP)accumulation. The trace PSP content in the mackerel Scomber japonicus liver was previously demonstrated in the Buenos Aires province coastal region (Carreto et al, 1993a),and a certain capability to accumulate the toxins was suggested.However, it was up to spring 1993 when a great number of PSP intoxicated mackerels where detected for the first time in a wideshelf area off the Buenos Aires province. This area, known as 'El Rincón' (39°00'-40°30'S), has become a growing importance mackerel fishing ground during the last few years. A high PSP concentration was determined in those mackerels, being the...

Autores: Wöhler, O.C.; Cordo, H.D.; Hansen, J.E.; Cassia, M.C.
The current status of southern blue whiting Micromesistius australis stock is described. A single, closed fish population is assumed to inhabit the SW Atlantic. Based on catch data corresponding to years 1987-1997, a sequential analysis on the stock is carried out (Cohort Analysis). Under an adaptative framework, catch per unit of effort data from commercial vessels are used to fit the model. Two commercial fleets are used in the fitting, i.e. Polish vessels (1987-1994)and Argentine surimi factory vessels (1991-1997). Results indicate that both, total stock biomass and spawning stock biomass would have declined. Total biomass would have decreased from a maximum close to 1.4 million tons in 1990 down to 0.5 mt in 1997 whereas the current spawning stock...

IODE's Role in Managing and Exchanging Ocean Data from Coastal Zones
Provedor de dados: 20
The coastal zones in the world are exposed to continuously increasing environmental stresses: pollution, eutrophication, erosion problems which are amplified by steadily growing economic and recreational use and demographic changes. In view of the position of the coastal environment as a buffering zone and interface between land and open ocean, an effort in integrated coastal zone management is required to achieve sustainable development. Besides the possible impact of global climate change also coastal flood protection and related safety aspects are of vital importance to the coastal population, as well as for environment and economy. By their nature, coastal processes are not confined to regional or national boundaries so their solution requires an...

El enigmático bivalvo Planktomya henscni ha sido considerado como un animal holoplamónico por casi un siglo. Alien and Scheltema (1972) demostraron que toda la evidencia indicaba hacia una concha bentónica con un estado larval inusitadamente largo.  Esta concha bentónica ha sido encontrada finalmente en la parte tropical del Atlántico occidental, y aparentemente pertenece a la familia Sportellidae. Al compararla con las especies fósiles de esta familia muestra un tendencia hacia una prodisoconcha grande y un largo estado larval planctónico, aparentemente largo.

Blood is Thicker than Water: The Evolution of Coastal Management in South Africa
Provedor de dados: 20
Autores: Glavovic, B.C.
Like people in many nations, South Africans value their coastal resources and are striving to manage them more effectively (Cicin-Sain &amp; Knecht 1998; CMPP 1998, 2000; Glavovic 2000 a, b, c; Glavovic et al. 2001). The White Paper for Sustainable Coastal Development in South Africa aims to promote sustainable coastal development through integrated coastal management. This new policy represents a marked shift from earlier views of the coast and how it should be managed. What was, until relatively recently, a predominantly biophysical and bureaucratic view has been transformed into a participatory approach driven by human development imperatives and the need to promote sustainable livelihoods. How did this transformation take place, and what lessons might...

Fisheries and the Environment. Policy Implementation and Fisheries Resource Management: Lessons from Senegal
Provedor de dados: 20
Fishing plays an important role in the Senegalese economy and society. Indeed, it is a multipurpose activity that contributes towards reducing the balance of payments deficit, reducing unemployment and satisfying the protein needs of the population. Despite its importance, the fishing sector is facing serious socioeconomic disequilibria, which has lead to overfishing and the use of harmful methods of production. This, in turn, has resulted in the shortage of supplies to local markets and a reduction in protein intake for populations dependent on fishing. Furthermore, the strong tendency to export Senegalese piscatorial products has led to a shift in focus of the fishing effort from locally consumed species (pelagic) to export oriented ones (demersal),...

Autores: Krakstad, J.O.
The horse mackerel (Trachurus capensis) stock is distributed from around Tomboa in Southern Angola (16°00’S) and throughout Namibia (Figure 1). The exchange of horse mackerel between Namibia and South Africa is not known but the horse mackerel stocks are considered as separate at least for management purposes. Juvenile fish is manly found inshore of the 200 m isobath and adults manly offshore of this. The mean size increases southwards with largest fish (&gt;35 cm) caught south of the Luderitz upwelling cell. The biomass in this area however is low and there is very little fishing on this part of the stock. The main concentration of fish is found in the north from around 17°00’S - 20°00’S. This is also where the main fishing pressure is. The stock has...

Coral reefs globally are increasingly under threat from environmental and anthropogenic factors, particularly the recent widespread bleaching and mortality of corals due to the temperature anomaly recorded during the 1997/98 El Niño. The active rehabilitation of reefs maybe necessary in some locations. Different rehabilitation methods require development for use in different conditions according to the constraints of area, availability of funding and reasons for rehabilitation. A number of studies have involved transplantation of parts of adult corals at a variety of technical, financial and spatial scales. Methods have included placement of loose staghorn Acropora branches (Bowden-Kirby, 1997; Lindahl, 1998) on suitable substrates, cementing corals to...

Recovery probabilities of coral reef communities after Acanthaster planci infestation: a case study at Shabror umm gam'ar, Hurghada, Red Sea, Egypt
Provedor de dados: 20
Autores: Ammar, M.S.A.
Recovery patterns of coral reef benthic communities were estimated by linear extrapolation after Acanthaster planci outbreak of 1998 at Shabror Umm Gam'ar, Hurghada of the Egyptian Red Sea. The significance of using linear extrapolation was tested in a range of ten sites by comparison with the actual average yearly recovery rates. A total of 15 permanent transects, each is 10m long, were monitored at 10m and 12m depths in both Shabror Umm Gam’ar and the ten selected sites. The recovery rate estimated by linear extrapolation did not significantly differ from the recovery rate of stony corals in the ten selected sites. Moreover, an error of +7.69% to +17.5% increase in the extrapolated recovery rate exists and should be considered while handling the...

The Chaenopsine blennies of the Southwestern Caribbean (Pisces: Clinidae: Chaenopsinae) I. Systematic analysis of zoogeography
Provedor de dados: 20
Autores: Acero-P., A.
The chaenopsine blennies are an homogeneous group which may be considered a subfamily of the Clinidae, since the existing evidence is not enough to give them familial status. The subfamily includes eight genera: Mccoskerichthys, Coralliozetus, Acanthemblemaria, Ekemblemaria, Emblemaria, Hemiemblemaria, Lucayablennius, and Chaenopsis. The nominal genera Protemblemaria and Emblemariopsis are herewith considered synonyms of Coralliozetus, since they share two derived characters: small size and sexual dimorphism in the color of the head, and are rather similar in several other characteristics. The división of the West Indian Zoogeographical Province made by Briggs (1974) is unnatural, since the fish fauna of Belize, Florida and the Bahamas is very similar. I...

Oceanographic and faunistic structures across an Angola Current intrusion into northern Namibia waters.
Provedor de dados: 20
Autores: John, H.C.H.; Mohrholz, V.; Lutjeharms, J.R.E.
It is thought that the penetration of Angolan waters through the Angola–Benguela Frontal Zone (ABFZ) into the much cooler Benguela regime may come about by a poleward slope undercurrent as well as by cross-frontal filaments. To test this hypothesis, two zonal transects off the northern Namibian coast were surveyed by CTD casts, current measurements and ichthyoplankton samples during April 1999. Simultaneous sea-surface temperature (SST), chlorophyll-a concentration, and wind data were obtained from satellite. The multidisciplinary results are described.An intense intrusion of the Angola Current into northern Namibian waters occurred with distinct signals of high temperatures and salinities, low chlorophyll-a concentration, and Angolan fish larvae of both...

Distribution of economic benefits from the fisheries of Lake Victoria
Provedor de dados: 20
Autores: Abila, R.O.; Odongkara, K.O.; Onyango, P.O.
The Lake Victoria fishery contributes immensely to the socio-economic development of the riparian states. The East African Community has designated the lake basin as an ‘economic growth zone’, with the potential to develop into a major economic region. The fisheries are vital in creating employment opportunities, mostly rural-based, thereby helping to reduce rural-urban migration. Fish is also a rich source of animal protein for human consumption and provides raw material (fishmeal) for processing animal feeds. The fish industry contributes to GDP and has continued to be an important source of foreign exchange earned from fish exports. Besides, the fish industry contributes to the national and local government revenues through levying of various taxes,...

Autores: Bautil, B.R.R.
Spiny lobster fishing in the Seychelles is an artisanal done essentially by skin divers operating at night in the shallow waters surrounding by the islands. Because of human population distribution lobster fishing grounds are concentrated on the inner granitic islands. In September 1992, a random stratified samoling program was set up to gather biological information from the entire granitic Mahe plateau. Direct census of fishery resources by Scuba divers swimming underwater transects was selected as the most feasible and expedient means by which to enact the Resource Survey. This report present partial result gathered for the survey around Mahe Island only and provides an estimate of the Maximum sustainable yield for the granitic plateau by extrapolation...

Seychelles tuna bulletin : second quarter 1987
Provedor de dados: 20
The number of purse seiners active in the Western Indian Ocean during the second quarter of 1987 decreased from 33 vessels during the previous quarter to a minimum of 29 in May, increasing to 30 in June. Good catch rates were obtained during this quarter averaging 16MT/day; the highest catch rate ever recorded during this period for this fishery.  The proportion of skipjack in the catch increased in April as vessels moved south to fish around the Mozambique Channel.  Although this fishing pattern is somewhat similar to that observed during the same period last year, it would appear from data obtained from logbooks that this year the purse seiners moved north one month earlier i.e. in June.  This resulted in an increase in the catch rate of yellow fin. As...

in many parts of the world, aquaculture production in the Mediterranean has been expanding rapidly over recent years. Total aquaculture production in the region reached 1,266,959 t in 1999, which represents approximately 6% of the world aquaculture production (3% in 1995). Although Mediterranean aquaculture still focuses more on mollusc production (53.9%), the share of fish production is progressing constantly (46% in 1999, and 35% in 1995), parallel to global trends of world aquaculture. The Mediterranean coast displays a wide range of geographical characteristics and supports many functions, such as tourism, residential development, and conservation, which may compete with aquaculture for resources. Many coastal areas are also physically exposed,...

The status of persistent organic pollutants in Lake Victoria catchment
Provedor de dados: 20
Autores: Madadi, O.V; Wandiga, S. O; Jumba, I. O.
The use of most organochlorine pesticides has been banned or restricted in the republic of Kenya under the Rotterdam and Stockholm convention due to high levels of persistence in the environment and toxicity to nontarget organisms. Studies conducted in some parts of the country have revealed that residue levels of these compounds are still in the environment. However, the residues of these compounds have not been exhaustively studied in the Lake Victoria catchment area. This study was set to investigate the residues levels of p,p-DDT, o,p’- DDE, p,p-DDD, g-HCH, D-HCH, a-HCH, Aldrin, and Dieldrin, in water samples from Lake Victoria catchment. Samples were collected during the short rain, dry and wet seasons and analysed using gas chromatography equipped...

Autores: Lung'ayia, H.B.O.
The African catfish Clarias gariepinus (Burchell), has an intermitent     occurrence in the Sondu-Miriu river draining into lake Victoria.     Observations were made to get basic information on size composition,     migration, spawning period and food of this species in the river. A     total of 376 fish samples of fish ranging from 11.9 to 101.1 cm in     total length were examined from January to December 1989. A migration     of the fish between the lake and the river waters is indicated. Small     sized and immature fish were available in the river throughout the     year but their numbers became minimal in the dry season. Large and     mature specimens were caught mainly during the high water mark and     rainy seasons of April-June and...

Pour l’étude biométrique de la squille Squilla mantis, un échantillonnage régulier a été réalisé dans le golfe de Tunis, le golfe de Hammamet et le golfe de Gabès de janvier 2005 à décembre 2006. Les équations morphométriques de la squille, dans le golfe de Gabès, ont montré que la croissance relative du telson, celle de la masse totale et celle de la masse éviscérée par rapport à celle du céphalothorax sont caractérisées par une allométrie positive. Par contre, la longueur totale croît négativement par rapport à celle du céphalothorax. Pour le golfe de Hammamet, ces caractères ont une croissance marquée par une allométrie négative à part la masse éviscérée. Les équations morphométriques de la squille du golfe de Tunis ont montré une allométrie positive...

Bar Beach Erosion Problem: Available Options Towards A Lasting Solution To The Erosion Problem
Provedor de dados: 20
Beach nourishment is the process of dumping sand on the beach to increase the width or the height of the beach. For along time this had been the most widely used on the beach. Table shows the many beach nourishment programs that have been implemented on the beach. While beach nourishment is regarded as soft and environmentally friendly method of combating coastal erosion it is a stopgap temporary measure. It requires periodic implementation. The return period of the nourishment programs since 1982 averages two years. This option is only a stopgap measure and not permanent. Hence this option cannot be viewed as a lasting solution to the problem.

Autores: Leta, H.R.
Los calamares dada su particular abundancia son 105 moluscos marinos de mayor importancia de las aguas uruguayas. Entre éstos, el calamar Illex argentinus es el recurso más importante del área. Si bien la tecnología de captura aplicada no es específica para el recurso, los volúmenes capturados con red de arrastre principalmente para merluza, por las unidades de la Flota Comercial de Altura Uruguaya, indican la existencia de una importante biomasa de estos cefalópodos. Estas consideraciones sumadas al fácil acceso a la zona de explotación y a la duración de la temporada de pesca, favorecen el establecimiento de una pesquería propia del recurso. En 1980, el programa de investigaciones de INAPE incluyó el estudio integral de la explotación de los calamares...

Review of Fisheries Biology of Scomberomorus and Acanthocybium Species in the Western Indian Ocean (FAO Area 51)
Provedor de dados: 20
Autores: Siddeek, M. S. M.
The seerfish group (Scomberomorus and Acanthocybium species) contributes less than 2% to the total landings from the western Indian Ocean (FAO Area 51, Fig. 1) (FAO 1994). Although its contribution is minor in quantity when compared with the landings of other major fish groups, it is considered as the prime fish in almost all the countries bordering this area. Seerfish fetch a higher price per kilogram than any other marine fin-fish landed in these countries. It is also a valuable export product in some of these countries (e.g., Oman). The high demand appears to have triggered over-exploitation of some stocks living in this region. Therefore, research studies are needed to assess these stocks to formulate appropriate management and development plans....

Ecosystem Considerations for Managing Marine Fisheries in the Indian Ocean
Provedor de dados: 20
Autores: Vivekanandan, E.
Fisheries management approach of several countries, including those in the Indian Ocean region, has been generally on a species-to-species basis. It has been realized now that this approach has severe limitations, especially for the tropical, multispecies fisheries. While the understanding that fish and other living aquatic living resources are integral part of their ecosystems is not new, this idea has not been put into practice in managing stocks, especially for the marine fish. Reshaping the management strategies by involving all the stakeholders in such an ecosystem approach is expected to yield short-term and long-term benefits

Distribution and community structure of butterflyfishes (Pisces: Chaetodontidae) in southern Mozambique
Provedor de dados: 20
Autores: Pereira, M.A.M.; Videira, E.J.S.
Even though Mozambique has the greatest reported diversity of butterflyfishes (24 species) of the continental states of the Western Indian Ocean region, aspects of the ecology and distribution of this group in Mozambique are poorly documented. The distribution, diversity and community structure of butterflyfishes were studied on nine reefs in southern Mozambique using the point count method. Nineteen species from four genera were identified. Three with generalist feeding habits (i.e. Chaetodon auriga, C. guttatissimus and C. interruptus) were the most abundant with a wide distribution range. The butterflyfish communities of intertidal reefs at Inhaca Island differed from those of the offshore, subtidal reefs, as shown by uni- and multivariate analysis of...

El Rodadero ha sido clasificado por la prensa colombiana y por la opinión pública como el "centro turístico de Colombia" o "la perla del Caribe". Más aún, se lo ha colocado entre la categoría de los balnearios lujosos internacionales, que existen en la región del Caribe (como Acapulco, Miami etc.).

This study focuses on assessing the state of population distribution, land cover distribution, biodiversity hotspots and protected areas in global coastal zones. The coastal zone is defined as land within 100 km of the coastline. This study attempts to answer such questions as: how crowded are the coastal zones, what is the pattern of land cover distribution in these areas, how many of these areas are designated as protected areas, and what is the state of the biodiversity hotspots. This study uses globally consistent and comprehensive geo-spatial data sets based on remote sensing and other sources. The application of modern Geographic Information System (GIS) layering methods and consistent data sets has made it possible to identify and quantify selected...

Stock assessment of the bluemouth (Helicolenus dactylopterus) in Azorean waters during the 1990-2002 period, applying a biomass dynamic model
Provedor de dados: 20
Autores: Perrotta, R.G.; Hernandez, D.R.
Bluemouth (Helicolenus dactylopterus), a benthic fish mostly inhabiting at depths between 500 m and 600 m, represents a highly valuable economic resource for local fishermen at the Azores Islands (NE Atlantic). Nominal catches of bluemouth increased from 1990 through 1994, and declined afterwards reaching in 1999 the lowest value recorded. Standardized catch per unit effort (CPUE) was used as an index for stock relative abundance; a General Linear Model, considering several factors that may have affected the fishing efficiency of commercial vessels, was run to obtain this CPUE index. These factors were: fleet type, year, month, and boat size; the last three factors were found to be statistically significant. A discrete version of the Schaefers Biomass...

Le Bénin est caractérisé par un réseau hydrographique assez dense, appartenant à deux grands bassins : le bassin du Niger au nord et le bassin côtier au sud. La côte est sablonneuse rectiligne et s’étend sur 120 km, avec un plateau continental de 3100 km2 chalutable sur 2700 km2. Sa production est estimée à 10300 tonnes en 1998. La pêche continentale est restée peu développée au Nord alors qu’au Sud on a assisté cette dernière décade à une surexploitation significative des plans d’eau en général. La production annuelle est estimée à 30 000 tonnes. Cette surexploitation des plans d’eau du sud Bénin est marquée par une multiplication des pêcheries sédentaires (barrages, parcs acadjas, trous à poissons) et l’utilisation d’engins dévastateurs, indépendamment...

Some Aspects of the Reproductive Biology of Kapenta, Limnothrissa miodon (Boulenger 1906) in the Cahora Bassa Reservoir, Mozambique
Provedor de dados: 20
Autores: Mafuca, J.
The reproductive biology of the Kapenta (Limnothrissa miodon), that supports the main commercial fishery in Lake Cahora Bassa (Mozambique) was investigated using monthly samples collected during 2003 and2004. This species was initially introduced in Lake Kariba in 1967/68 with the objective of filling up the pelagic environment that was created with dam closure. The fish is believed to have been able to negotiate the Kariba dam wall and became established in Cahora Bassa, some 250 km downstream, as well. The reproductive biology of Kapenta is known from Lake Tanganyika, where it is indigenous, and from Kariba,but no research has been performed, so far, in Cahora Bassa. Since many important biological attributes may vary from place to place, depending on...

Autores: Formoso, M.; Díaz, R.
La región monitoreada, fue objeto de captura comercial de cobo en el país. En 1999 se realizó un monitoreo del área que demostró una merma en los niveles de abundancia de la especie, probablemente debido a una sobre- explotación durante 1998, luego de uana moratoria nacional producto de los resultados de Ferrer y Alcolado (1994), así como un mal manejo y desconocimiento de las áreas de concentración. Esto motivó que el Centro de Investigaciones Pesqueras propusiera una veda total, con un plazo indefinido, hasta tanto se evidenciara una recuperación del recurso. Luego de 10 años de reposo, se visitaron las áreas tradicionales de pesca en el año 2009, que demostró que los niveles de abundancia fueron buenos y sobre la base de un manejo precautorio en cuanto...

Gear selectivity for three by-catch species in the shallow-water shrimp trawl fishery at the Sofala Bank, Mozambique
Provedor de dados: 20
Autores: Pinto, M.A.
The reduction of shrimp by-catch when fishing with shrimp trawlers can constitute a strategy to minimise discards. A research cruise was conducted in February 1995 in shallow waters off Sofala Bank, Mozambique to investigate the sorting (selection) efficiency of cod-ends (55mm and 60mm meshes) compared to the top-grid (14mm space bar) systems using covered cod-end method. The selectivity parameters were obtained for Otolithes ruber, Johnius dussumieri and Thryssa vitrirostris through the maximum likelihood estimate (MLE) method, using logit function and pooled samples through the variance component model (VCM) . The top-grid was mounted at a theoretical angle of 33°, one metre aft of the retriever strap, in a downward direction. The overall shrimp to...

Nematodes parásitos como indicadores biológicos de Macruronus magellanicus
Provedor de dados: 20
Autores: Incorvaia, I.S.; Hernandez, D.R.
A wide distributional range species can constitute many populations or fishing stocks which can be whole or partly overlapped within their distribution area, reason why they must be clearly identified. Therefore, proper identification of stocks is necessary for fisheries management, as this is the unit to which the fishing effort should be applied. The parasitological method is one of the systems currently used to determine stock. Nematodes parasites of Macruronus magellanicus (longtail hake) collected during surveys enmarked between 45º S-55º S in the Southwest Atlantic were studied. Nematodes that could be used as biological indicators were selected. Mean abundance values of L3 Anisakis simplex and Hysterothylacium aduncum were estimated. Three different...

Based on 25 hours shipboard ADCP measurements across semi-enclosed bay mouth(Kemen Channel), time series of tidal currents over 12 sites, which distribute evenly along the transect, were constructed to improve our understanding of tidal characteristics and residuals in this region. The tidal currents in Kemen Channel were identified as the regular semidiurnal and reversing tidal flows, with its behaviour more like standing waves. Moreover, the flood currents in the lower layers were found to be ahead of that in the upper layers and vice versa for ebb tides. The major of tidal ellipse for M2 constituent was found to be larger close to the southern side of the channel, with its incline also increasing toward the south. The signs of M4 constituent were also...

In our study length-weight relationship are presented for 213 Phycis phycis and 270 Phycis blennoides caught between September 2007 and August 2008 and collected from trawler fishing in the Gulf of Tunis. The lengthweight relationships and the condition factor were computed separately for sexes and for different seasons. The parameters of the length-weight relationship for the population as a whole are all well correlated (r2 &gt; 0.92, p &lt;0.001). The type of growth is isometric for P. phycis while it is majorant allometry for P. blennoides. The comparison of the regression of the weight according to the total length of males and females, of the two species, shows that the growth is therefore identical. The study of seasonal variations indicates that...

Autores: Artiles, A.; Rodríguez, I.; Pérez, A.; Pérez, L.; Espinosa, G.
Se estimó la variabilidad genética y el índice de parentesco entre lotes de camarón blanco del Pacífico, Litopenaeus  vannamei, introducidos por quinta ocasión en Cuba, procedentes del Centro de mejora del camarón, de Estados  Unidos (Shrimp Improving System: SIS), para su cultivo. La variabilidad genética se estimó mediante el genotipo de  33 muestras con cuatro loci microsatélites: M1, Pvan 1815, Pvan 0040 y Pvan 1758. El quinto lote de Litopenaeus  vannamei tuvo los valores promedios de heterocigosidad esperada y observada, más bajos de todos los introduci- dos en Cuba: 0.37 y 0.27, respectivamente. Esto, unido a la poca cantidad de variantes alélicas para cada región  microsatélite, indica una escasa variabilidad genética. Los valores del coeficiente...

Durante la reproducción de camarones peneidos en cautiverio se ha observado que las hembras, a pesar de encontrarse bajo las mismas condiciones de maduración y de que provengan de una población homogénea en cuanto a edad y tamaño, presentan un diferente potencial reproductivo. Esto es, se ha observado que un alto porcentaje (75%) de hembras no desova o produce desoves no viables, mientras que un bajo porcentaje de hembras (25%) tienen la capacidad de desovar múltiples veces, produciendo estas la mayoría (50% -70%) de nauplios. Dado que el mantener en producción hembras con nulo o bajo desempeño reproductivo implica altos costos para los productores (alimento y espacio), se ha sugerido usar sólo múltiples desovadoras para incrementar el rendimiento por...

Autores: Irusta, C.G.; Aubone, A.; Simonazzi, M.A.; Ibañez, P.M.
In this paper detailed mathematical description of the generalized lineal model used and data grouping criteria are presented in order to estimate the relative fishing power of four categories of the hake ice-chilled fleet. The analysis was focused to the patagonian sector (41°-48°S) of the hake total distribution area.The fleet has systematically operated in the same fishing areas between 1989-1993. The variables that better explain in yields trends of each vessel category were analyzed. The fishing power of vessels with power higher than 1200 HP has been raising since 1990 because of increasing efficiency. These vessels generate three times more fishing mortality than the standard vessels (lower than 700 HP)

Peatlands act as information traps; archives reflecting changes in climate and environment, through pollen assemblages, sediment facies, plant fibre and C14 dating. The investigation of Maputaland peatlands presents an ideal opportunity to understand these changes during the Late Pleistocene and Holocene. The Maputaland peatlands in South Africa could be geographically divided into two distribution areas based on age: The Holocene age peatlands northwards of the Mkuze River inflow into Lake St. Lucia and the Late Pleistocene age peatlands south of this inflow. The grouping of peat thicknesses versus peat ages in a scatter diagram indicates distribution deviations from the ideal accumulation line. These might represent periods of low or negative growth and...

Coral reefs play a crucial role in the well being of coastal communities in Tanzania (Johnstone et al., 1998; Muhando, 1999). However, despite their usefulness, coral reefs are being degraded by destructive anthropogenic activities (Salm et al., 1998) and natural causes (e.g., competition, predation, diseases, bleaching, etc.). The coral bleaching and mortality event of March - June 1998 was the most serious natural calamity ever recorded in the Indian Ocean (Wilkinson, et al., 1999). Several areas along the coast of Tanzania were affected. The degree of coral mortality varied between sites, from 60% - 90% at Tutia Reef in Mafia Island Marine Park and Misali Reef on the west coast of Pemba, to approximately 10% on reefs around Unguja Island, Zanzibar...

L' urbanisation constitue pour les pays d Afrique sub-saharienne l élément clé de son processus de peuplement. Commencé plus tard que dans les autres régions du monde, le peuplement s' est accéléré rapidement, donnant lieu à une mobilité vers les villes depuis la fin de la Deuxième Guerre mondiale et surtout après les indépendances (Snrech 1994, Dubresson 1996). La région entre dans un processus d urbanisation extrêmement rapide, caractérisé par un processus de restructuration et de concentration du peuplement au bénéfice des villescapitales. Kalasa (1993) caractérise la vitesse du processus d urbanisation comme tout à fait exceptionnelle, sans égale dans aucune région du monde ni à aucune autre époque.

Mauritius: Indian Ocean haven for pirate fishing vessels
Provedor de dados: 20
Pirate fishing is fishing conducted outside the framework of any national or regional fisheries management regime. Technically it is referred to as  Illegal, Unregulated and Unreported  (IUU) fishing. Poaching within Exclusive Economic Zones (EEZs, the national 200-mile zones around coastal states) is a serious pirate fishing problem. The world s major fisheries are concentrated in the waters overlying the continental shelves as these areas support larger populations of fish and because these depths are easier for fishermen to reach. As a result of overfishing, many of these fisheries have collapsed or are in decline. The competition for the remaining fish is intense. This has lead to further unregulated or uncontrolled pirate fishing in international...

According to the analysis of otoliths edge, birthday was established on 1st July. Within the age range observed, that comprised 3-18 year old specimens, age groups 7, 8 and 9 were the most frequently identified in both sexes. Growth parameters estimates showed significant differences between them.

Determinación del contenido de metales pesados en las fracciones geoquímicas del sedimento superficial asociado a los manglares de la Ciénaga Grande de Santa Marta, Colombia
Provedor de dados: 20
Autores: Espinosa, Luisa Fernanda; Parra, Juan Pablo; Villamil, Carlos.
El ecosistema de manglar de la Ciénaga Grande de Santa Marta (CGSM) ha estado sometido a fuertes presiones antropogénicas que han ocasionado, entre otros, cambios en las características fisicoquímicas de sus sedimentos. En condiciones normales, los sedimentos asociados al manglar generan equilibrios que permiten la retención de metales pesados en distintas formas químicas, al romperse este equilibrio los metales que no son retenidos en la matriz sedimentaria, pueden ser removilizados y hacerse biodisponibles. Con el propósito de establecer el potencial de movilidad y biodisponibilidad  de los metales Cr, Mn, Ni, Cu, Zn, Cd, As y Pb en sedimentos superficiales asociados al manglar en la CGSM, se analizaron sus contenidos en cuatro áreas con diferente grado...

Spatio-temporal variations of zooplankton community in the hypersaline lagoon of Bardawil, North Sinai, Egypt
Provedor de dados: 20
Autores: Mageed, A.A.A.
Bardawil Lagoon is a shallow oligotrophic hypersaline lake, located at the northern periphery of Sinai peninsula-Egypt, connected to SE Mediterranean Sea through two main openings known as Boughazes. Distribution of zooplankton in Bardawil Lagoon during 2004 was studied, not only in space and time but also with reference to species assemblages and environmental factors. Copepoda, Protozoa, and Mollusca were dominating the lagoon zooplankton community during the period of study with 58 identified forma. Zooplankton stock peaked during August and October with severe depletion in spring. Spatially, the maximum density occurred near the sea opening I.  The lowest density and species richness were noticed at stations with high salinity. The community...

Ulva reticulata and Gracilaria crassa: Macroalgae That Can Biofilter Effluent from Tidal Fishponds in Tanzania
Provedor de dados: 20
Autores: Msuya, F.E.; Neori, A.
Macroalgae (seaweed) can be cultured effectively for the production of useful algal biomass and removal of nutrients from fishpond effluents. A land-based, tide/gravity-driven flow-through, fish-macroalgae integrated system was studied at Makoba Bay, Zanzibar, Tanzania, during May-October, 2000. Rectangular cages made of 1-inch mesh netting were constructed in channels that received the outflows of the fishponds. Four species of macroalgae were planted in the cages and compared for their usefulness as biofilters. Gracilaria crassa and Ulva reticulata grew at average rates of 1.5 and 1.2 %, respectively. Both species removed nitrogen as seaweed protein at rates of up to 0.4 g N/m2/d. The algal biomass produced was of good quality with protein dry weight...

State of Biodiversity: Western Cape Province, South Africa Mammals
Provedor de dados: 20
Autores: Lloyd, P.H.
The Western Cape Province (W.C.P.) of South Africa, one of nine provinces forming the country, is generally regarded in South African terms as being “poor” with respect to the number of its mammals when compared to the other eight provinces. This misconception has its origin in the fact that the Western Cape, essentially a winter rainfall region, lies adjacent to one of the richest spots in the world in terms of mammalian diversity, namely the summer rainfall region of the rest of South Africa. In fact only when compared with the rest of our own country can the Western Cape be regarded as having a “poor” mammofauna in terms of biodiversity. However, some of the other Western Cape vertebrate and many of the invertebrate groups do reflect higher levels of...

La poliploidía ha sido una de las biotecnologías más empleadas en la ultima década para el mejoramiento genético de moluscos bivalvos por ser una de las mejores alternativas a corto plazo para incrementar la producción. Los organismos triploides presentan tres juegos completos de cromosomas homólogos que afectan la sinapsis, lo cual da como resultado una esterilidad parcial o total, la cual teóricamente repercute favorablemente en el crecimiento. Sin embargo, la inducción a la triploidía presenta algunos problemas que podrían resolverse con la disponibilidad de tetraploides para producir triploides biológicos. En este trabajo se presentan los resultados del desarrollo de biotecnologías de poliploidía en tres especies de moluscos nativos al noroeste de...

Possible upwelling phenomenon off the Nigerian coast
Provedor de dados: 20
Autores: Ibe, A.C.; Ajayi, T.O.
Published information favour the occurrence in certain years of wind related upwelling in Nigeria's inshore waters especially between July and September.  This is corroborated by the prevalence of petroleum source beds, glauconite, phosphorite and periodic abundance of some fish including Engraulis encrassicolus, Sardinella maderensis and the bonga Ethalmosa fimbriata which are pelagic and are associated with upwelling phenomena.  Examination of temperature and salinity data for 1978 - 81 suggested that upwelling occurred during certain periods of each year.  However, wind data for the same period lacked details to support postulates of wind driven upwelling.  Instead, dynamic upwelling resulting from the juxtaposition of the currents in the area is...
