New coastal and marine management strategies have recently been developed in many countries and regions. From an ecosystem approach perspective, the aim of such strategies is the maintenance of ecosystem integrity while enabling the sustainable use of ecosystem goods and services. There is, however, a need for harmonized definitions and standardized processes to deal not only with the interjurisdictional and multidisciplinary complexities that are associated with such strategies but also with the extensive timelines and resources implicated in the planning and implementation of these strategies. The ecosystem-based management system proposed here is based on three pillars that facilitate the integration of an ecosystem approach to coastal and oceans policy...

The Mediterranean region is of fundamental importance to Europe given its strategic position. The responsibility for its overall ecosystem integrity is shared by European Union Member States (EU-MS) and other Mediterranean countries. A juxtaposition of overlapping governance instruments occurred recently in the region, with the implementation of both the Marine Strategy Framework Directive (MSFD) for EU-MS and the Ecosystem Approach Strategy (ECAP) for all Mediterranean countries, including EU-MS. Both MSFD and ECAP are structured around vision-driven processes to achieve Good Environmental Status and a Healthy Environment, respectively. These processes have clear ecosystem-based, integrated policy objectives to guarantee the preservation and integrity of...

Influence de l'azote et du phosphore sur la croissance et la toxicité de Prorocentrum lima (Ehrenberg) Dodge
Provedor de dados: 5
Autores: Morlaix, Martine; Lassus, Patrick.
Very few attempts have been made in order to investigate the role of nutrients on cellular growth and toxin production in dinoflagellates associated with DSP (Diarrhetic Shellfish Poison). Some preliminary results are presented here, aiming at a better knowledge of inorganic nitrogen and organic phosphorus effects upon division rate and toxin content of Prorocentrum lima (PL2V spanish strain). Nitrogen have a positive effect on growth rate, up to a threshold value of 880muM.l-1. Above this threshold the rate decreases. There is no effect on toxin content since okadaic acid and DTX1 cell contents remain low (4.8 +/- 0.5 pg.cell.-1) and steady. Phosphorus effect upon division rate follows a non-linear relationship, whereas cellular toxic content is inversely...

Évaluation du risque chimique dans l’environnement marin : exemple d’application aux installations industrielles du Nord-Cotentin
Provedor de dados: 5
Autores: Marchand, Michel; Tissier, Chrystele.
In the context of the European legislation on chemicals (existing, new chemicals and biocides) a risk assessment for the environment and human health is performed. A technical guidance document (TGD), in support of Commission Directive 93/67/EEC on risk assessment for new notified substances and Commission Regulation (EC) No1488/64 on risk assessment for existing substances has been developed in 1996 and was recently adapted for the marine environment. The methodological concept is based on the relation between a value representing the contamination level of a chemical substance in the environment (exposure assessment) and a value representing its effects on the environment (effects assessment). The exposure value is expressed as PEC for “Predicted...

Utilisation d’espèces halieutiques exploitées comme indicateurs de la contamination chimique en zone littorale
Provedor de dados: 5
Autores: Abarnou, Alain.
The concept of biological indicator relies upon the assumption that the contamination measured in biological tissues reflects that of the aquatic environment. This study aims to update the knowledge on contamination levels of various chemical contaminants in a few exploited fish species from various areas along the French coastline. The objective of the work is to evaluate the possibility of differentiating the various coastal zones according to the contamination levels measured in fish living there. Several groups of contaminants were followed: PCBs (marker PCBs and dioxin-like PCBs), dioxins (PCCDs and PCDFs), PBDEs, PFCs and total mercury). These contaminants were mainly measured in four fish species: the sea bass (Dicentrarchus labrax), the mackerel...

Climatic trends in continental shelf waters off Ghana and in the Gulf of Guinea, 1963-1992
Provedor de dados: 5
Autores: Koranteng, Ka; Mcglade, Jm.
Using time series analyses, some physical parameters of the continental shelf waters of the Gulf of Guinea were examined. Analysis of coastal sea surface temperatures from Ghana and Ivory Coast, and offshore sea surface temperatures from the Gulf of Guinea clearly shows spatial and inter-annual patterns of cooling in coastal waters of West Africa. The behaviour of the decomposed trend of coastal and offshore sea surface temperatures, sub-surface: temperature measured at 100 m depth off Ghana and salinity showed that the observational period (1963-1992) could be divided into three climatic periods: the period before 1972, from 1972 to 1982, and the period after 1982. In the first period, sea surface temperature at both coastal and offshore areas and bottom...

La surveillance des phycotoxines dans les coquillages du milieu marin. Le réseau REPHY : objectifs, stratégies, et principaux résultats
Provedor de dados: 5
Autores: Belin, Catherine.
The surveillance of phycotoxins in marine shellfish. The REPHY network: objectives, strategies and primary results One of the objectives of REPHY (network for phytoplankton and phycotoxin surveillance) is to monitor toxin-producing micro-algae species in the marine environment that are likely to accumulate in seafood products, and to screen for these toxins in shellfish. This surveillance is undertaken in the framework of the European regulations. Three groups of toxins are thus monitored and are associated with three genera of toxic phytoplankton: (i) Dinophysis, a producer of the okadaic acid (with diarrhoeic effects) and pectenotoxin families of toxins; in the same group of so-called “lipophilic toxins”, two other families of regulated toxins are...

Le chrome en milieu marin
Provedor de dados: 5
Autores: Chiffoleau, Jean-francois.
This document constitutes a synthesis of current knowledge on the chromium biogeochemical cycle. The natural and anthropogenic sources are evaluated, the fluxes between the various geochemical compartments are assessed, with special attention to the riverine and atmospheric inputs to the marine environment. Chromium levels in these compartments are described and show in several areas a very high contamination of marine organisms. Due to the important toxicity of this element, further investigations are absolutely required to better understand its behaviour in the marine environment.

Surveillance du milieu marin et protection santiaire des coquillages
Provedor de dados: 5
Autores: Renault, Tristan.
Shellfish farming is a major economic activity in the European Union, France being one of the main producing countries. Regulations were introduced to meet society's current expectations in terms of food safety at the fishing, farming and harvesting stages, as weil as during processing and marketing. Toxic algae, pathogens or pollutants may contaminate shellfish products during production and harvesting, partly because of the particular environ mental conditions in which these animais are grown. Monitoring programmes were thus deve/oped to detect the presence of biological and chemical contaminants in coastal waters and in shellfish, and to monitor the food safety of the latter.

La pisciculture marine : un secteur industriel en émergence
Provedor de dados: 5
Autores: Paquotte, Philippe; Harache, Yves.
In a general context of low progression, European aquaculture has been characterized by the development of intensive fish farming. The most notable fact is the recent increase in intensive salmonid farming, with a turnover of almost two million ECU. More recently, the intensive farming of sea bass and sea bream has increased very rapidly in the Mediterranean Basin, although on a more reduced extent. Although research has started as soon as the seventies with a strong public incentive both for salmon, sea bass and sea bream, the development of these different types of aquaculture has not been done at the same pace. Some elements of sectorial dynamics are analysed such as research planning and financing, organization of the production and public policy. For...

Impact de l'aquaculture marine sur l'environnement : aspects juridiques et économiques
Provedor de dados: 5
Autores: Paquotte, Philippe.
Aquaculture is an economic activity which is characterised by a great dependence on environmental conditions. Therefore aquaculture development is subdued to institutional context which defines the rules for use and conservation of the environment. This paper analyses the impact of marine environment regulations on economic operating of aquaculture enterprises and on industrial dynamics. Because aquaculture enterprises use a collective good, an economic approach of aquaculture has to take into account not only the relations between enterprises and environment, but also the relations between the enterprises themselves, through production externalities. In this study, several economic tools are considered in order to incite enterprises to integrate pad of...

Défis de la surveillance des maladies chez les coquillages marins en France
Provedor de dados: 5
Autores: Lupo, Coralie; Francois, Cyrille; Arzul, Isabelle; Garcia, Celine; Joly, Jean-pierre; Renault, Tristan.
The basic concepts and objectives of animal disease surveillance are common to all types of animal production. Yet, the procedures for implementation have been mostly developed for terrestrial animal productions. Disease surveillance in marine shellfish calls for specific measures in view of the peculiarities of marine biology and rearing techniques. The main objective of disease surveillance in marine shellfish is to detect as early as possible exotic and newly emerging diseases. With this objective in mind, a national surveillance network for surveillance of mollusc diseases called Repamo has been developed. It combines passive reporting and risk-based surveillance.

Présence d'un Protogonyaulax sp. sur le littoral atlantique français pendant l'hiver 1987
Provedor de dados: 5
Autores: Lassus, Patrick; Bardouil, Michele.
A dinoflagellate belonging to Protogonyaulax genera and forming more than 20 cells chains was observed from November 1987 to February 1988 in Vilaine Bay and in the west ofIle d'Yeu (France). This species was not detected in coastal phytoplankton during preceding surveys. Close to Protogonyaulax affinis it seems to be a winter developing species for this coastal area. Vertical distribution shows in december a migration of the patch towards deeper layers. Increasing occurrences of species belonging to Protogonyaulax (Alexandrium Balech) genera inshore or coastal waters need to pay more attention to the taxonomy of such organisms. Some species are effectively well known as poisons producers.

Fluorescent antibody enumeration of Vibrio cholerae in the marine environment.
Provedor de dados: 5
Autores: Brayton, P; Roszak, D; Palmer, L; Huq, S; Gimes, D.
From microcosm studies, V. cholerae and related potential human pathogens enter a viable but nonculturable state. Direct viable counts by epifluorescent microscopy consistently remain higher than corresponding plate counts. Thus, the assumption that pathogens "die-off" or "decay" in the marine environment must be re-evaluated, since stressed or nutrient-starved cells are unable to grow and be enumerated by standard plate count methods. Indirect immunofluorescent microscopy offers a more sensitive detection system for environment sampling for human pathogens. Field indicate that cultures positive for V. cholerae O1 are also positive by fluorescent antibody staining; however, the reverse was not necessarily true. By adapting epifluorescent techniques for...

Electricité de France (EDF) has asked Institut Français de recherche pour l'exploitation de la mer (IFREMER) to monitor the coastal marine environment and its living resources around nuclear power plants along the French coast. Started in 1974, these investigations were undertaken in the areas of Gravelines, Le Blayais, Paluel, Flamanville, and Penly; the objective is to detect any impact of the open-circuit water cooling system, as well as any differences in the marine environment itself. To examine this question, IFREMER has set up a program called Impact des Grands Aménagements (IGA). It has evolved according to the results obtained and now integrates the specificity of each site in a global program common to all. The nature and the problems of impact...

During the years 1972-1993, kepone a persistent pesticide has been used in the banana fields of the French West Indies (Martinique and Guadeloupe) to content a weevil. A slow desorption of the molecule from soil induces its transfer to the sea through the rivers from leaching and erosion. This study intended to take stock on the contamination by kepone of the fishery species around the islands fifteen years after the kepone ban. Furthermore other chemical pollutants were sought in fish and shellfish around the Martinique island.   The results confirmed persistence of marine fauna contamination by kepone, mainly in the alluvium areas in front of polluted rivers. They shown also that this contamination may spread more widely but with fast decreasing through...

Water and sediment samples monthly collected from Arcachon Bay (Gironde, France) were examined during three years for the presence of marine vibrios. V. cholerae serotype 01 was never detected. On the other hand, the Eyre River and mouth contain non-agglutinating V. cholerae (127 strains) principally in water. The low temperatures slow their development down without stopping it completely. V. parahaemolyticus (257 strains) present in the same areas is particularly isolated from water when the aquatic medium temperature rises to 15 degree C. V. alginolyticus (638 strains) settles the whole Bay, except the river, in any season. The low temperatures promote growth of V. metschnikovii (203 strains) very tolerant towards salinity.

Chemical contamination of the coastal marine environment by polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) was assessed along with emerging contaminants such as polybrominated diphenyl ethers (PBDEs) in an industrially well-developed country (France) and a fast-developing country (Korea). Other chemicals, i.e. nonylphenol (NP) and 5 beta(H)-cholestan-3 beta-ol (coprostanol) were determined to trace industrial waste and/or domestic inputs. These compounds were analyzed in coastal sediments and mussels in two enclosed coastal water bodies: Masan Bay (South Korea) and Thau lagoon (France). The overall levels of target organic contaminants were higher in Masan Bay than in Thau lagoon. The mean concentrations of 17 PCDD/Fs,...

La pollution chimique marine. Quelles politiques pour une protection durable de l'océan et des mers côtières ?
Provedor de dados: 5
Autores: Marchand, Michel.
The coastal marine environment presents some specificity compared to other aquatic environments: it is both the receiving end of pollution on land and the most biologically rich marine area, where are developing many uses (fisheries and aquaculture, salt production, tourism, thalassotherapy). The coastal zone is therefore vulnerable to chronic chemical pollution and its protection requires research, monitoring and regulation. A dual strategy can be put into place: a preventive approach to avoid placing on the market of toxic substances to humans and the environment, and a retrospective approach based on public policies for the protection and restoration of degraded aquatic environments.

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...

The IOC-IMO-UNEP/GIPME Groups of Experts on Effects of Pollution (GEEP) has been working for a number of years on promoting new ways of understanding how pollutants affect marine biological systems. A major initial focus of GEEP was on calibration workshops where different methods were tested against one another. The Oslo (1986), Bermuda (1988) and Bremerhaven (1992) workshop publications are widely regarded as benchmarks demonstrating that biological effects  methods are reliable tools for measurement of the effects of pollutants discharged to the marine  environment. IOC through GEEP, in cooperation with UNEP, has published a series of manuals based on the successful techniques and these are listed at the back of this volume.  Monitoring programmes for...

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...

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...

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...

Autores: Ruarte, C.O; Rico, M.R.
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 percentages of variance explained in the...

Chemical analysis of some macrophytes in Mariut and Edku lakes, Egypt
Provedor de dados: 20
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...

Projet pour le développement rationnel et durable du secteur de la pêche au Sénégal (INT/07/16M/SPA)
Provedor de dados: 20
Autores: Perrine Anderson.
Description du secteur de la pêche Avec la Mauritanie, le Sénégal est de loin le plus grand producteur de produits de pêche de la sous région. Avec 718 km de cote et un territoire maritime de 198km2, 15 745 km2 de superficie fluviale, 2 estuaires, des mangroves et un lac de 350km2, le Sénégal possède tous les atouts des plus grands producteurs de pêche. Le potentiel annuel de captures s’élève à 500 000 tonnes. Le secteur a subi une croissance spectaculaire ces trente dernières années : les débarquements sont passés 50 000 tonnes en 1965 à plus de 450 000 en 1997. Le secteur se compose principalement de deux sous-secteurs : la pêche industrielle et la pêche traditionnelle ou artisanale. Cette dernière, vielle de plusieurs siècles a su s’adapter et se...

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...

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...

Zygochlamys patagonica (King and Broderip, 1832) is an ecosystem engineer mollusk which forms aggregations or banks, of different densities, in the main frontal systems of the SW Atlantic Ocean. The objectives of this work were to analyze the composition, biomass, diversity and species richness of the benthic invertebrate assemblages at different scallop densities as well as the variability of their trophic webs at high and low scallop densities. For this, samples of the benthic invertebrate assemblages were taken at the Shelf Break Front with a non-selective epibenthic dredge. It was evaluated if the abundance (ind/m2) or biomass (colonial species, gr/m2) of the different taxa varied with scallop densities. The results showed that from 14 analyzed, the...

Effects of subsidised distant water fleets on the marine environment and local people in Western Africa
Provedor de dados: 20
Autores: Zeba, S.
These last years, while adressing marine conservation problems in Western Africa, 3 major issues were generally raised by our local partners: -Most of the distant water fleets fishing in the coastal waters of other countries do not often abide by the international standards of responsible fishing; -The number of distant water fleets is steadily increasing in the Exclusive Economic Areas of developing countries; -Theses fleets have tremendous ecological and economic consequences, which resulted in a crisis of fishery management. Yet it is thanks to fishing agreements that distant water fleets have legal access to the fish resources of developing coastal countries.More important: it is thanks to subsidies that the behaviours of distant water fleets have such...

La présente étude a pour but de déterminer l’organotropisme de quatre métaux traces (Cd, Pb, Hg et Zn) ainsi que leurs concentrations dans le zooplancton et dans trois organes (muscle, foie et branchies) de la sardinelle (Sardinella aurita) provenant du golfe de Tunis.  Les résultats ont montré que les concentrations moyennes des quatre métaux dosés (Cd, Pb, Hg et Zn) sont plus élevées dans la sardinelle que dans le zooplancton. Ceci est dû à la bioamplification de ces éléments dans la sardinelle qui occupe un niveau trophique élevé de la chaîne alimentaire marine.  Pour le Pb, le Hg et le Zn,  les teneurs le plus élevées ont été enregistrées dans les branchies de la sardinelle, alors que  le Cd est concentré davantage au niveau du foie. Les concentrations...

This second volume of a guide to integrated coastal zone management opens a new dimension by discussing the processes involved in a more complete and dynamic way than the first, To fulfil1 this requirement, an expanded work group, drawing upon the knowledge of experts in political science, economics, and sociology, devoted over two years of effort (1999 - 2001) to its completion, following a disciplined working method. A dual principle prevailed in the application of this method. On one hand, it prescribed an approach structured as a series of steps, and on the other, it demanded that real situations be brought to light, emphasizing case studies of experience with or analysis of coastal management.

Autores: Khaled, A.
The concentration of seven heavy metals (Cd, Cu, Fe, Mn, Ni, Pb and Zn) were detected seasonally in muscle tissues of two fish species (Siganus rivulatus, Sargus sargus) collected from El-Mex Bay and Eastern Harbour. In both species, levels of the seven metals were significantly higher in summer compared with other seasons. The concentrations of such metals decreased in the order Fe &gt; Zn &gt; Cu &gt; Ni ≥ Pb &gt; Mn &gt; Cd. The metal pollution index (MPI) for the two species fluctuated between 0.9 and 1.8 in El-Mex and Eastern Harbour. Provisional Tolerable Weekly Intake (PTWI) demonstrates that the concentration of the metals (Cd, Cu and Pb) in the muscle of Siganus rivulatus and Sargus sargus from El-Mex Bay and Eastern Harbour are much lower than...

Autores: Moriondo Danovaro, P.
The study on distribution and abundance of eggs and early planktonic stages of red shrimp, Pleoticus muelleri (Bate, 1888), contributes to a better knowledge of the species dynamics. Results from processing and analyzing 72 plankton samples collected with Bongo net during two research cruises on board of FV “Arbumasa XVIII” and RV “Capitán Oca Balda”, carried out in the Patagonian littoral in March 2008 and January 2009, are presented. In both cruises, eggs and larval stages were found all over the study area. The highest punctual densities of eggs were recorded in the area known as “La Pared” (46° 45’ S-65° 55’ W and 46° 50’ S-65° 55’ W). Eggs indicate the presence of shrimp reproductive concentrations which, while migrating eastwards towards waters of...

Análisis de la utilización de la captura por unidad de esfuerzo de pescadilla de red (Cynoscion guatucupa) como índice de abundancia anual. Período 1992-2004
Provedor de dados: 20
Autores: Perrotta, R.G.; Ruarte, C.O.
The stripped weakfish (Cynoscion guatucupa)  caught in Brazil, Uruguay and Argentina (SW Atlantic) has a wide latitudinal distribution (22° S-43° S). In Argentina there are two main fishing areas, the Argentine-Uruguayan Common Fishing Zone and 'El Rincón', southern zone of the Buenos Aires littoral. The importance of the species makes it necessary to define an annual abundance index that would allow to diagnose the state of the stock. The model adjusted to calculate the index is the General Linear Model. The factors used were Year, Quarter, Length, Stratum (4 categories) and sub-areas (5 categories), all statistically significant. The problem generated by the presence in the model of first order interactions that include the Year factor is discussed. The...

El rol del frente de mareas de Península Valdés en el control de la comunidad zooplanctónica
Provedor de dados: 20
Autores: Derisio, C.
The Península Valdés tidal front was studied in its rol in the control of the spatial distribution, abundance, assemblages, diversity and life histories of the zooplankton community using samples from two oceanographic surveys. Although the front showed in general high zooplankton abundances, highest values, mainly due to the presence of immature stages of copepods, were recorded in the transitional and stratified zones coinciding with highest values of chlorophyll a. The zooplankton groups showed a distinctive spatial distribution across the front. The results showed that this front did not exert any control on zooplankton composition and diversity, but did on the abundance. In the homogeneous zone the harpacticoid copepods were more abundant, followed by...

Autores: Irigoyen, A.J.
This study investigates the impact of Undaria pinnatifida on the reef  fish assemblage associated with the coastal rocky reefs of Golfo Nuevo in northern Patagonia, Argentina. Undaria pinnatifida is a laminarian kelp, indigenous to the temperate regions of Japan, China and Korea. It has spread around the world by international shipping and has also been introduced in some regions for mariculture. Its expansion into the northern Patagonian gulfs and Peninsula Valdes, a UNESCO Natural Heritage Site, may threaten eco-tourism activities that depend on local biodiversity and the esthetic quality of the ecosystem. In particular, there is concern about the impact of Undaria on a variety of recreational activities including diving, angling and spear fishing, which...

The Marine Environment in Angola: Threats and Methods of Management
Provedor de dados: 20
Autores: Sardinha, M.d.L.
The Angolan sea is an important centre of marine biodiversity and biomass of zooplankton, fish, sea birds and marine mammals, and supports also an important reserve of oil and gas. Fishing resources are important sources of proteins and employment as well as a significant source of income of foreign currency. Angola has become in recent years a major producer and exporter of oil in Africa. The utilization of the resources can be negatively influenced if management options are not appropriately implemented. The knowledge of the ecosystem, the dynamic of the resources and the factors that have a negative impact on the environment is important to manage the ecosystem on a sustainable way.

Spawning and reproductive variables of the northern hake stock were analyzed using macroscopic and histologic gonad information derived from samples collected in May 2009. The study includes estimates of batch fecundity, spawning frequency, oocyte dry weight and size at first maturity. During May 2009 the reproductive activity of the northern hake stock took place mainly near the 50 m isobath, north of 37° S. Spawning occurred within a temperature range of 9 °C-15 °C that coincided with a bottom thermal front. Size at first maturity, much lower than that reported at the beginning of the 1980s, showed differences between males (27.16 cm TL) and females (32.84 cm TL). The reproductive frequency was estimated at one spawning every 13 days and mean batch...

Estandarización de la captura de centollón (Paralomis granulosa) por trampa con distintos tiempos de pesca en el Canal Beagle, Argentina

Autores: Firpo, C.; Wyngaard, J.; Iorio, M.I.
To standardize false king crab catch rates and transform them into abundance indices it is essential to count on a model that adequately describes the relation between catch per trap and fishing time. Considering data derived from research surveys carried out on board of the artisanal fleet in the Beagle Channel, assuming an asymptotic catch trend and absence of escape, to describe the relation an exponential model was applied. The Coo (asymptotic catch) and a (income rate) parameters of the model allowed to build a correction factor to transform the catches obtained with different fishing times into relative abundance indices. The model provides, besides, the optimum time to maximize catches. Para estandarizar las tasas de captura de centollón y...

Throughout this colloquium reference has been made to a number of environmental problems, most of them due to human activities (e.g. clearing mangrove forests, dynamite fishing, sewage pollution, etc.). While attempts are being made to correct these problems through new legislation and educating adults in more environmentally friendly practices, it is my thesis that we should be putting much more effort into the environmental education of young, school-age children since such efforts will, in the long run, have the greater impact on environmental awareness.

Determination of nitrate ion in marine biotopes with high nitrate content by ultraviolet spectrophotometry
Provedor de dados: 27
Autores: Mertens, J.; Massart, D.L.
A simple and rapid method for the determination of nitrate in seawater of high nitrate content (&gt;1 ppm) is proposed. The absorption of the nitrate ion is measured at 210 and 220 mµ. The sample is treated with a measured quantity of hydrochloric acid to eliminate the carbonate and bicarbonate interferences and measured against a nitrate free blank prepared by reduction of the nitrate to ammonia with Raney nickel. The addition of HCl permits also storage of the sample without special precautions and the use of the blank eliminates the most serious of the interferences (bromide) expected in seawater. The interference of organic matter limits however the applicability of the method to concentrations higher than 1 ppm.

A case study of the effects of ship emissions on the microphysical, radiative, and chemical properties of polluted marine boundary layer clouds is presented. Two ship tracks are discussed in detail. &lt;i&gt;In situ&lt;/i&gt; measurements of cloud drop size distributions, liquid water content, and cloud radiative properties, as well as aerosol size distributions (outside-cloud, interstitial, and cloud droplet residual particles) and aerosol chemistry, are presented. These are related to remotely sensed measurements of cloud radiative properties. The authors examine the processes behind ship track formation in a polluted marine boundary layer as an example of the effects of anthropogenic particulate pollution on the albedo of marine stratiform clouds.

Provedor de dados: 27
Autores: Vranken, G.; Herman, P.M.J.; Heip, C.H.R.
Aspects of the demography of &lt;i&gt;Monhystera disjuncta&lt;/i&gt; were investigated at different feeding conditions (monoxenic cultures with different bacterial strains, and different densities in the feeding suspension with one strain). Embryonic development time, minimum generation time, egg deposition rate and adult longevity depend on temperature, quality and quantity of food offered. Body mass at maturity is an allometric function of food density. It is shown that a previously inferred selectivity in food uptake is an artifact of culture conditions. pH buffering and addition of sterols permit culture of the species on a wide variety of bacterial strains. &lt;i&gt;M. disjuncta&lt;/i&gt; is less well adapted to take advantage of high food density...

Determination of methanesulfonic acid and non-sea-salt sulfate in single marine aerosol particles
Provedor de dados: 27
Autores: Kolaitis, L.N.; Bruynseels, F.; Van Grieken, R.; Andreae, M.O.
In open ocean waters the predominant volatile sulfur compound is dimethyl sulfide (DMS), representing almost 90% of the marine sulfur emissions. Methanesulfonic acid (MSA), one of the oxidation products of DMS, is consequently an important constituent of marine aerosols. Laser microprobe mass analysis (LAMMA) has been used for single-particle analysis of particles collected in the marine boundary layer. MSA, like the non-sea-salt sulfate, is mainly associated with the smallest aerosol particles, whose LAMMA spectra match the reference fingerprint spectra of MSA salts, sodium methanesulfonate and ammonium methanesulfonate. The presence of nitrate and heavy metal ions in the LAMMA spectra can reveal, to a certain extent, the degree of air pollution at the...
