Use of otolith-shape analysis for stock discrimination of Boops boops along the Algerian coast (southwestern Mediterranean Sea)
Provedor de dados: 5
Autores: Ider, D.; Ramdane, Z.; Mahe, Kelig; Dufour, Jean-louis; Bacha, M.; Amara, R.
Otolith-shape analysis was examined to determine its utility for biological stock identification of the bogue Boops boops along the Algerian coast of the Mediterranean Sea. The outlines of 179 sagittal otolith pairs from fish collected at three locations (Oran, Bejaia and Annaba) between 2013 and 2016 were digitised and analysed for shape variation by elliptical Fourier analysis. Potential confounding sources of variation (fish length, age and sex, and left or right otolith position) were examined and accounted for in the analyses before interpretation of spatial differences in distribution of the stock. Redundancy analysis showed a significant difference between the left and right otoliths. No difference was correlated with sex and age, but fish length...

Two examples of nutritional pathology related to vitamins E and C deficiencies
Provedor de dados: 5
Autores: Baudin Laurencin, F; Messager, J; Stephan, Gwendal.
Symptoms recalling a nutritional pathology and more precisely a process of lipid peroxydation were observed during the last years in seabass Dicentrarchus labrax and other fishes cultured in tropical marine condition, Ocyurus chrysurus and Lutjanus analis . They included dark coloration, skin ulceration, lethargy, anorexy, emaciation. Histological examinations showed hepatic fatty degenerative lesions, pancreatitis, muscular degeneration and retinal atrophy. Additional vitamins E and C in the food suppressed that pathological symptoms. The previously evoked clinical or histological signs were not achieved in spite of an increase of the level of hepatic, muscular or blood malondialdehyde and of the conjugated dienes of the perivisceral fat. In the same...

Modelling species distributions using regression quantiles
Provedor de dados: 5
Autores: Vaz, Sandrine; Martin, C; Eastwood, P; Ernande, Bruno; Carpentier, Andre; Meaden, G; Coppin, Franck.
1. Species distribution modelling is an important and well-established tool for conservation planning and resource management. Modelling techniques based on central estimates of species responses to environmental factors do not always provide ecologically meaningful estimates of species-environment relationships and are being increasingly questioned.   2. Regression quantiles (RQ) can be used to model the upper bounds of species-environment relationships and thus estimate how the environment is limiting the distribution of a species. The resulting models tend to describe potential rather than actual patterns of species distributions.   3. Model selection based on null hypothesis testing and backward elimination, followed by validation procedures, are...

Geographic isolation and larval dispersal shape seascape genetic patterns differently according to spatial scale
Provedor de dados: 5
Autores: Dalongeville, Alicia; Andrello, Marco; Mouillot, David; Lobreaux, Stephane; Fortin, Marie-josee; Lasram, Frida; Belmaker, Jonathan; Rocklin, Delphine; Manel, Stephanie.
Genetic variation, as a basis of evolutionary change, allows species to adapt and persist in different climates and environments. Yet, a comprehensive assessment of the drivers of genetic variation at different spatial scales is still missing in marine ecosystems. Here, we investigated the influence of environment, geographic isolation, and larval dispersal on the variation in allele frequencies, using an extensive spatial sampling (47 locations) of the striped red mullet (Mullus surmuletus) in the Mediterranean Sea. Univariate multiple regressions were used to test the influence of environment (salinity and temperature), geographic isolation, and larval dispersal on single nucleotide polymorphism (SNP) allele frequencies. We used Moran's eigenvector maps...

Sperm features in turbot (Scophthalmus maximus): a comparison with other freshwater and marine fish species
Provedor de dados: 5
Autores: Suquet, Marc; Billard, Roland; Cosson, Jacky; Dorange, Germaine; Chauvaud, Laurent; Mugnier, Chantal; Fauvel, Christian.
This paper presents some features of turbot sperm and compares them with data reported in the literature on other freshwater and marine fish. In captivity, turbot spermiation period lasts 6 months. When compared to other fish species, turbot males are characterized by low values of maximum gonadosomatic index (0.6-0.8%) and are poor sperm producers in terms of volume (0.2-2.2 ml), concentration (0.7-11.0 x 10(9) spermatozoa/ml) and total sperm number released per stripping (0.2-12.0 x 10(9) spermatozoa). Compared to most freshwater species, the duration of cell movement is long (1-17 min). The spermatozoon of turbot can be considered to be of a primitive type. A very high protein content (8.8 mg/ml) is found in the seminal fluid of turbot. Increasing...

Production of live prey for marine fish larvae
Provedor de dados: 5
Autores: Kraul, S.
Tropical marine fish larvae vary in their requirements for live planktonic food. Selection of live prey species for culture depends on larval size and larval tolerance of water quality. This report describes some of the cultured prey species, and their uses and limits as effective food for fish larvae. Methods are presented for the culture of phytoplankton, rotifers, copepods, and other live feeds.

Comparison of individual-based model output to data using a model of walleye pollock early life history in the Gulf of Alaska
Provedor de dados: 5
Autores: Hinckley, Sarah; Parada, Carolina; Horne, John K.; Mazur, Michael; Woillez, Mathieu.
Biophysical individual-based models (IBMs) have been used to study aspects of early life history of marine fishes such as recruitment, connectivity of spawning and nursery areas, and marine reserve design. However, there is no consistent approach to validating the spatial outputs of these models. In this study, we hope to rectify this gap. We document additions to an existing individual-based biophysical model for Alaska walleye pollock (Gadus chalcogrammus), some simulations made with this model and methods that were used to describe and compare spatial output of the model versus field data derived from ichthyoplankton surveys in the Gulf of Alaska. We used visual methods (e.g. distributional centroids with directional ellipses), several indices (such as...

Marine fish spermatozoa: racing ephemeral swimmers
Provedor de dados: 5
Autores: Cosson, J; Groison, A; Suquet, Marc; Fauvel, Christian; Dreanno, Catherine; Billard, R.
After along period of spermatogenesis (several weeks to months), marine fish spermatozoa are delivered at male spawning in seawater (SW) at the same time as ova. In some fish species, as the ova micropyle closes quickly after release, these minute unicells, the spermatozoa, have to accomplish their task of reaching the micropyle within a very brief period (several seconds to minutes), for delivery of the haploid male genetic information to the ova. To achieve this goal, their high-performance motile equipment, the flagellum, must fully activate immediately on contact with the SW and then propel the sperm cell at an unusually high initial velocity. The cost of such 'hyperactivity' is a very rapid consumption of intracellular ATP that outstrips the supply....

The contribution of ancient admixture to reproductive isolation between European sea bass lineages
Provedor de dados: 5
Autores: Duranton, Maud; Allal, Francois; Valiere, Sophie; Bouchez, Olivier; Bonhomme, Francois; Gagnaire, Pierre-alexandre.
Understanding how new species arise through the progressive establishment of reproductive isolation (RI) barriers between diverging populations is a major goal in Evolutionary Biology. An important result of speciation genomics studies is that genomic regions involved in RI frequently harbor anciently diverged haplotypes that predate the reconstructed history of species divergence. The possible origins of these old alleles remain much debated, as they relate to contrasting mechanisms of speciation that are not yet fully understood. In the European sea bass (Dicentrarchus labrax), the genomic regions involved in RI between Atlantic and Mediterranean lineages are enriched for anciently diverged alleles of unknown origin. Here, we used haplotype-resolved...

Hormone-induced spawning of cultured tropical finfishes.
Provedor de dados: 5
Autores: Marte, C.
Commercially important tropical freshwater and marine finfishes are commonly spawned with pituitary homogenate, human chorionic gonadotropin (HCG) and semi-purified fish gonadotropins. These preparations are often administered in two doses, a lower priming dose followed a few hours later by a higher resolving dose. Interval between the first and second injections may vary from 3-24 hours depending on the species. Variable doses are used even for the same species and may be due to variable potencies of the gonadotropin preparations.

Autores: Kodo, Jean-louis.
Fishes and fishery products are seafoods which have a nutritive value with a high proteins rate. Fishery products ionization has four steps: the radappertization (sterilization of the seafood), the radicidation (destruction of the pathogen germs), the radurization (food conservation and microbial flora reduction), the desinsectization (insects and parasites elimination). Fishery products quality control is very important

Conséquences à long terme d'une exposition précose à l'hypoxie sur la physiologie du bar européen (Dicentrarchus labrax) et de la sole commune (Solea solea)
Provedor de dados: 5
Autores: Vanderplancke, Gwenaelle.
The dissolved oxygen in seawater has steadily declined in many coastal marine ecosystems in the last 50 years because of global warming and increasing coastal human activities. This decrease in oxygen in seawater causes episodes of hypoxia increasingly frequent and severe in coastal and estuarine areas. Some organisms may escape these environmental constraints by migration or dispersion. Others, with limited swimming capabilities must implement physiological regulation (phenotypic plasticity) to enable them to adapt and survive. This is particularly the case of marine fish larvae that are likely to be present in coastal nursery at the end of their development. It is now well established that the regulations implemented by organisms to cope with their...

Interspecific differences in the effect of fish on marine microbial plankton
Provedor de dados: 5
Autores: Villeger, Sebastien; Fouilland, Eric; Argenty, Jeremy; Bouvier, Corinne; Carre, Claire; Bouvier, Thierry.
The productivity of most marine ecosystems is limited by the availability of dissolved nitrogen (N) and phosphorus (P). Nutrient recycling is therefore a key process for ecosystem functioning. Fish recycle nutrients through the excretion of ammonia and phosphate and can influence the abundance and community structure of primary producers such as phytoplankton. However, the effect of fish on other plankton compartments, and whether all fish species have similar effects, is largely unknown. We used a tank experiment to test how 2 Mediterranean fish species, gilthead seabream Sparus aurata and golden mullet Chelon auratus, with distinctly different N and P excretion rates, can affect the abundance and community structure of 3 plankton compartments:...

Population structure of the common sole (Solea solea) in the Northeastern Atlantic and the Mediterranean Sea: revisiting the divide with EPIC markers
Provedor de dados: 5
Autores: Rolland, Jean-luc; Bonhomme, Francois; Lagardere, Francoise; Hassan, M; Guinand, Bruno.
Spatial and temporal population genetic structures of the common sole, Solea solea, were studied in Northeastern Atlantic and Mediterranean Sea populations, using three polymorphic exon-primed intron-crossing (EPIC) markers. Results demonstrated significant multilocus differentiation among Eastern Mediterranean and a group composed by Western Mediterranean and Atlantic populations (theta = 0.150, P &lt; 0.001), but also suggested unrecorded genetic differentiation of the Adriatic Sea population. No pattern of isolation-by-distance was recorded across the range covered by sampling, from the Kattegat to the Aegean Sea. Conversely to genetically structured Mediterranean populations, Atlantic populations ranging from Denmark to Portugal could be considered as...

Maturation and spawning of tropical and subtropical marine finfish by environmental manipulations
Provedor de dados: 5
Autores: Roberts Jr, D.
Circannual, diel, and lunal periodic mechanisms in naturally reproducing stocks of tropical and subtropical fishes are reviewed. Manipulations of biological clocks, used to control reproduction in captive broodstocks, are detailed. Experiments to induce controlled maturation and spawning in fishes either test efficacy of changing environmental conditions (regimes), or constant environmental conditions (controlled). Data have been generated in experimental/scientific studies, as well as applied research. Effects of controlled environmental regimes on serum steroids, gametogenesis, spawning, fry performance and egg quality are summarized for selected members of Centropomidae, Serranidae, and Sciaenidae.

Définition d'un modèle d'élevage larvaire intensif pour la daurade Sparus auratus
Provedor de dados: 5
Autores: Ounais-guschemann, Nadia.
This study defines rearing parameters for mass products of 30-day old post larvae. Continuous lighting (600 lux) optimizes the predatory activity and suppresses the feeding rhythm. For 4-5 mm larvae (15 days), food ingestion slows down if the prey concentration in the tank is below 5 rotifers/ml, while there is no such threshold for 6-7 mm larvae (22 days). The rotifer Brachionus plicatilis , between 100 and 200 mu m, is an adequate initial prey, it can be replaced by Artemia salina for 7-8 mm larvae (30 days). It is observed that free amino acids and essential fatty acids contents have a prominent role in larvae growth; docosahexaenoic acid (C22:6n-3) content could be determined. Finally, the development of the swim bladder is facilitated by the renewal...

Distribution patterns of oceanic fishes in the Atlantic Ocean. Selected problems.
Provedor de dados: 5
Autores: Krefft, Gerhard.
Some problems in the geographical distribution of oceanic midwater fishes in the Atlantic Ocean are discussed. Remarkable differences were observed in the latitudinal distribution of mesopelagic fish species in the North Atlantic Ocean. These can be related to the oceanic circulation. The Gulf Stream system gives rise to a discontinuity in the position of the oceanic Polar Front. This front, a sharp bounary between subpolar and subtropical waters, follows the northern edge of the Gulf Stream in the western part of the Ocean. East of about 25 degree W the Polar Front becomes weak and untraceable. Relatively warm, high-saline-water of the North Atlantic Current flows North and northeastward by the spreading of the Mediterranean Intermediate Water. Due to the...

Nutritional bioenergetics and estimation of waste production in non-salmonids
Provedor de dados: 5
Autores: Kaushik, Sadasivam.
The general principles behind the bioenergetic approach for predicting growth, as well as for decreasing feed and nutrient losses, have been set forth for salmonids. Given the diversification of fish farming activities around the world and the ever increasing concern for water quality management, it becomes essential to verify whether an approach developed for salmonids is applicable to other species. Given this general background, an attempt is made here to check the theoretical assumptions and technical considerations behind the bioenergetic principles developed for rainbow trout with other freshwater or marine species. From a conceptual point of view, recent literature data do indicate that as far as nitrogen or energy balance is concerned, the general...

Biological and economic factors in the selection of cultured fish species and the development of a bio-economic model
Provedor de dados: 5
Autores: Wu, R.
The selection of candidate species for mariculture is determined by a number of biological factors, e.g. foraging efficiency, growth efficiency, mortality, grow-out period and susceptibility to environmental fluctuations, disease and crowding, as well as economic factors e.g. the supply and price of fry, grow-out cost and price of adult. A computer model incorporating these major factors is being developed, to determine and compare the potential of different culture species.

Autores: Cresson, Pierre; Travers-trolet, Morgane; Rouquette, Manuel; Timmerman, Charles-andre; Giraldo, Carolina; Lefebvre, Sebastien; Ernande, Bruno.
Whether considered as a risk for human health or as ecological tracers, contaminants' concentrations measured in fish muscles are commonly expressed relative to wet or dry mass. Comparison of results required conversion factors (CF) but accurate values are scarce and case-specific. The present paper is aimed at investigating errors linked with the use of the theoretical value. Muscles dry and wet masses were measured in 15 fish species to determine the actual CF. Most CF were lower than the theoretical wet:dry ratio of 5 classically used, with variations at individual and species level. Muscle lipid content (inferred by C/N ratios) was a crucial factor explaining discrepancies, claiming for caution when working with lipid-rich species. The observed...

Restricted dispersal of the reef fish Myripristis berndti at the scale of the SW Indian Ocean
Provedor de dados: 5
Autores: Muths, Delphine; Tessier, Emmanuel; Gouws, G.; Craig, M.; Mwale, M.; Mwaluma, J.; Mwandya, A.; Bourjea, Jerome.
The reef fish Myripristis berndti (Jordan &amp; Everman 1903) is a pantropical species. A genetic analysis was conducted on 353 individuals from 10 localities distributed across the SW Indian Ocean (SWIO) in order to determine patterns of connectivity in the SWIO. Both the mtDNA sequences (711-bp cytochrome b sequences) and the microsatellites (8 newly developed loci) reveal spatial patterns of differentiation within the SWIO. There is, however, a discrepancy between the structure observed with each kind of marker. MtDNA revealed that 3 peripheral populations (NW Kenya, SE Reunion, and SW Europa) were isolated from the 7 more central populations, which form a more densely connected population network, while microsatellite data indicated a more restricted...

In South America, the Pleistocene was characterized by important environmental changes related to glacial cycles, which had significant effects on the evolutionary history of several marine species. To evaluate the pattern of demographic history and the genetic structure of striped weakfish Cynoscion guatucupa, a 401 bp fragment of the mitochondrial Cytochrome b gene was sequenced from 92 individuals from three coastal areas in Argentina and one in Brazil in the southwestern Atlantic. Haplotype diversity was high, whereas nucleotide diversity was low among all sampling sites. The star-like pattern was not phylogeographically structured, in agreement with the AMOVA analysis.

ABSTRACT The Brazilian North coast is one of the world’s most important shrimp fishery grounds, with a total area of approximately 223,000 km2. However, the available data on the diversity of fish caught by the region’s industrial trawler fleet are limited to the commercially-valuable species. This lacuna in the data on the region’s marine fish fauna is worrying, both for the management of stocks and the conservation of the local biodiversity. The present study was based on a comprehensive inventory of the teleost fishes captured by the industrial outrigger trawling operations off the North coast of Brazil. This inventory recorded 201 species belonging to 64 families and 20 orders, and revealed a unique fauna, characterized by 17 endemic species, and a...

Hematological and biochemical characteristics during the transport of dog snapper Lutjanus jocu (Perciformes: Lutjanidae)
Provedor de dados: 83
Autores: Oliveira,Bruno L.; Souza,Rodrigo M.; Silva Filho,Jorge P.; Gomes,Levy C.; Fernandes,Luiz F. Loureiro.
ABSTRACT The objective of this study was to evaluate stress responses in dog snapper (Lutjanus jocu) during transport by evaluating their hematological and biochemical responses. Twenty-five wild dog snapper specimens were used in the experiment (220 ± 68 g and 24.5 ± 2.5 cm total length). Blood samples were collected prior to transport (control), and fish were placed in two transport boxes, one with anesthetic and one without anesthetic. Immediately after transport and after 24 h, blood was collected from the fish that underwent each treatment (with anesthetic and without anesthetic). Biochemical and hematological results demonstrated the inefficiency of benzocaine as a stress reliever during handling and transport. Biochemical parameters revealed the...

Assessment of egg quality at early embryonic stages may be useful predictive criterion to evaluate the potential mass juvenile production in red porgy Pagrus pagrus. The objective of the present study is to describe in detail the embryonic developmental stages in the red porgy and the time taken by larvae to hatch at three incubation temperatures. Fertilized eggs obtained from natural spawnings were incubated at 15, 20 and 25°C. Photomicrographs of all the embryonic stages were taken at the three temperatures. Cell divisions after fertilization and organ appearance during the embryonic development were identified. The sequence in cellular divisions and appearance of sensory and motor organs were the same for the three temperatures, although the higher the...

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...

Fish and shellfish samples for total mercury analysis were provided by the local fish export industry. Data collected through the years 1981-83 are processed and information was obtained on actual total mercury values in edible muscle of sampled species. On the basis of these results, future trends in mercury concentration values are hoped to be predicted. The authors suggest a revision of standards in force at present and the proposal of new ones, taking into account species involved and size of specimens.

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...

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.

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...

Todos los organismos multicelulares son susceptibles a enfermedades, por lo que estos han desarrollado sistemas de defensa contra los organismos patógenos, y los peces no han sido la excepción. Su sistema inmune al igual que el resto de los vertebrados puede dividirse en dos tipos: el sistema inmune adaptativo y el sistema inmune innato. Ambos poseen componentes celulares y humorales. Dentro de los componentes humorales del sistema inmune innato se encuentran los péptidos antimicrobianos (AMPs), los cuales son típicamente de 12-50 aminoácidos con una carga neta positiva de +2 a +7. Debido a que los AMPs pueden desplegar una actividad de amplio espectro contra una gran variedad de patógenos y algunas células cancerosas, el interés de estos ha aumentado...

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,...

Estudio comparativo de los pejerreyes marinos del área marplatense
Provedor de dados: 20
Autores: Hirt Chabbert, J.A.
Los pejerreyes son peces muy apreciados por el hombre, debido a la exquisitez de su carne. Habitan tanto las aguas dulces y salobres como las marinas. La gran semejanza entre todos ellos y su adaptabilidad a los diversos medios, son factores que hacen muy dificil la identificación específica. La mayoría de los ictiólogos que se han ocupado hasta ahora del tema en la Argentina, no han publicado los resultados de sus investigaciones, por 10 cual se cuenta con unos pocos trabajos antiguos (Berg, 1895; Devicenzi, 1924; Lahille 1929a, 1929b y 1930; Marrero, 1950) y claves recientes elaboradas sobre los datos provenientes de esos trabajos (Menni et al., 1984).

Efficiency of co-feeding red porgy (Pagrus pagrus L.)larvae with live and compound diet
Provedor de dados: 20
Autores: Aristizabal, E.O.; Suárez, J.
The red porgy (Pagrus pagrus)is an important commercial and recreational species with very good prospect for aquaculture. Because significant mortalities, the mass production of this species is limited. This paper describes three weaning strategies to investigate their effects on the survival and growth of red porgy larvae reared in laboratory: A)traditional three-step weaning (rotifers - Artemia - diet)(control); B)one-step early weaning by co-feeding (rotifers - Artemia + diet), and C)one-step direct early weaning (rotifers - diet). Sigificative differences were recorded among treatments (P0.05). Best survival rate (45.6 ± 7.6 percent)and growth (7.4 ± 0.5 mm)were found in treatment B. Results indicate that co-feeding red porgy larvae with inert and live...

Provedor de dados: 20
Autores: Martínez, R.A.
El cultivo de peces marinos ha atraído considerable atención en la última década, experimentando un gran auge en años recientes. Esto se debe principalmente al desarrollo y optimización de la tecnología de cultivo en jaulas, como también al mejoramiento de las técnicas de producción de juveniles, lo que ha incrementado el número de especies para las cuales existen cultivos de orientación comercial. En las circunstancias actuales, para que el cultivo de peces sea rentable es necesario controlar todas las fases del ciclo vital de la especie. En el presente trabajo se abordó esta problemática a través de estudios enfocados a la maduración gonadal y desove a través de tratamientos de temperatura y fotoperíodo denominados no invasivos.

Nematodes parásitos como indicadores biológicos en las especies Macruronus magellanicus y Merluccius hubbsi (Pisces, Gadiformes)
Provedor de dados: 20
Autores: Incorvaia, I.S.
Parasites nematodes as biological tags of Macruronus magellanicus (longtail hake) and Merluccius hubbsi (hake) colleted between 34°- 55°S in the SW Atlantic were studied. Adult specimens of Hysterothylacium aduncum, Ascarophis marina and Ichthytofilaria argentinensis, and the third-stage specimens of H. aduncum, Anisakis simplex and Contracaecum aduncum were described. Histological studies showed that I. argentinensis provokes tissue reactions in the swim bladder of  M. hubbsi.  A wide distributional range of species can be represented by many fish populations or fishing stocks. As these can overlap in space, the proper identification of stocks is necessary for fisheries management. The parasitologic method is one currently used to determine stocks....

Two groups of adult Mutton snapper fish Lutjanus analis captured in the wild, each one of three females and four males, were kept during eight months under controlled temperature and photoperiod conditions in the lab in order to stimulate their sexual maturation which was in a state of latency because of the effects of confinement. The first group was maintained under an artificial cycle with temperature manipulation and the second under a control cycle, in which this parameter was left at natural conditions. Every two months blood samples from all females were taken for the analysis of plasma testosterone (T) and oestradiol (E2) levels, taking ovarian biopsies simultaneously to register the mean diameter of the oocytes. After six months, a significative...

Seasonal concentrations of some heavy metals in muscle tissues of Siganus rivulatus and Sargus sargus fish from El-mex bay and eastern harbour, Alexandria, Egypt
Provedor de dados: 20
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...

Lack of mtDNA differentiation among hamlets (Hypoplectrus, Serranidae).
Provedor de dados: 20
Autores: García-Machado, E.; Chevalier, P.; Solignac, M.
The hamlets are a group of vividly colored fish species of the Serranidae family differentiated only by the color pattern of the body. Although there are divergent views about hamlet taxonomy, experimental and field observations have shown a strong assortative mating, justifying a species status for the different color morphs. Here we analyze the level of evolutionary divergence among six species in respect of mitochondrial DNA, with a view to contrasting the pattern observed with color partitions and previous results obtained with isozymes. The estimated molecular distance among species was low and of the same magnitude as nucleotide diversity within species. Consequently, the net distance and hence the time of divergence between taxa was virtually zero...

The spatial and temporal changes of the fish assemblage areas composition at the coastal ecosystem of the western South Atlantic (34 degree -41 degree S) during six springs (1981, 1983, 1994, 1995, 1998 and 1999), were examined. For each assemblage area the most common species and those species that discriminate it from adjacent assemblages areas within years, were identified. Within each area, also resident (common in all years) and facultative (contributing to less than 90% of similarity within any year) species, were studied. Also were identified what parameters control the main structuring of the fish community on the spatial and temporal patterns. In order to determine how the environmental factors influenced the fish community structure, the...

Little is known about the ichthyofauna of the São Tomé and Príncipe archipelago. Since the early works of Osório, at the turn of the century, only few attempts were made to update and complete existing knowledge on fish systematics and biodiversity from this area. Over the past few years, however, several surveys made it possible to start an inventory of the coastal fishes for the archipelago. These are mainly based on specimens that where captured or observed whilst diving and also on fishes landed on beaches by local artisanal fishermen. A total of 124 species belonging to 108 genera and 61 families was identified. Some specimens, including Serranidae, Gobiidae and Labridae probably belong to undescribed species and are currently being studied.

Broodstock management and induced spawning of flounder Paralichthys orbignyanus (Valenciennes, 1839)under a closed recirculated system
Provedor de dados: 20
Autores: Bambill, G.A.; Oka, M.; Radonic, M.; López, A.V.; Müller, M.I.; Boccanfuso, J.; Bianca, F.
The present study was conducted to determine the parameters regulating spawning performance of P. orbignyanus wild broodstock. The adaptation to captivity was successfully achieved with minimal stress levels. In three consecutive spawning seasons, the annual photothermal manipulation was not effective for the maturation and natural spawning of females although males were running. Females were HCG injected, releasing non fertilized eggs. Artificial fertilization was carried out after stripping the fish with a total production of 18,000 fertilized eggs in 2001 (egg diameter=800±10 µm), 55,300 in 2002 (egg diameter= 850±12 µm)and 1,635,000 fertilized eggs in 2003 (egg diameter 818.4 ±30.08 µm, oil drop 98.1 ±2.96 µm). For the study of the ovulationtime,...

Autores: Díaz-M., J.M.
Las mandíbulas secas de cuatro especies de tiburones carcharh inicios (Galeozerdo cuvieri, Carcharhinus albimarginatus, C. galapaguensis y C. porosus) del Pacífico oriental tropical fueron examinadas para determinar las tasas de remplazo dental de cada especie. En general, las tasas de remplazo fueron mayores en la mandíbula inferior que en la superior, y esta diferencia fue más grande en aquellas especies en las que la diferenciación morfológica entre los dientes superiores e inferiores es más notable. Además, las mandíbulas cuyos dientes tienden a ser más anchos que largos tienen tasas de remplazo menores que aquellas cuyos dientes tienden a ser más largos que anchos. Esto es debido posiblemente a la mayor capacidad de tensión de los dientes anchos y a...

Rearing techniques for difficult marine fish larvae
Provedor de dados: 27
Autores: Dhert, Ph.; Divanach, P.; Kentouri, M.; Sorgeloos, P.
In finfish mariculture, seed production and larval rearing still form the bottleneck for all ongrowing operations and are considered as the main limiting factor for industrial development. Through trial and error more than through biological understanding two opposite hatchery techniques have been developed which surprisingly control a multiparametric combination of different factors but aspire to the same objective of conformity with wild standards and the cost-effective production of larvae. In intensive aquaculture, the rearing technique is characterised by high initial larval densities in small tanks under strict hydraulic, thermic, and nutritional conditions. The light conditions are artificial. The temperature and quality of water are controlled. The...

Early postlarval fish in the hyperbenthos of the Dutch Delta (south-west Netherlands)
Provedor de dados: 27
Autores: Beyst, B.; Mees, J.; Cattrijsse, A.
Early (post)larval fish constitute a significant part of the temporary hyperbenthos, i.e. of the fauna living in the lower reaches of the water column close to the substratum. Information on the densities and spatial and temporal variations of these stages, as well as on their lengths at the moment of occurrence, can be an important contribution to the knowledge of their dispersion, migrations and to the identification of possible bottlenecks in their recruitment. Therefore the hyperbenthos of the Voordelta, a shallow coastal zone in front of the Dutch Delta, as well as that of the subtidal channels and the intertidal brackish marsh creeks of the Westerschelde Estuary, was sampled monthly during one year by means of a sledge and a stow net. A total of 37...

An oral challenge for turbot larvae with &lt;i&gt;Vibrio anguillarum&lt;/i&gt;
Provedor de dados: 27
Autores: Chair, M.; Dehasque, M.; Van Poucke, S.; Nelis, H.; Sorgeloos, P.; De Leenheer, A.P.
There is a need for a standard in vitro procedure to infect larval fish with bacteria. Such a procedure could be used as a tool to evaluate fish quality, verify fish sensitivity to a certain bacterial strain or evaluate the pathogenicity of a bacterium towards a given fish species. The availability of a challenge test is a prerequisite in studies dealing with the effect of different medicinal treatments on diseased fish. An oral challenge test would offer the possibility to investigate the routes of infection via the digestive tract, i.e. after feeding contaminated feeds. The present study aims to verify this hypothesis and proposes a standard challenge procedure for turbot (&lt;i&gt;Scophthalmus maximus&lt;/i&gt;) larvae with a pathogenic &lt;i&gt;Vibrio...

Fish oil replacement by soybean oil in the diet of fat snook juveniles
Provedor de dados: 86
Autores: Bendhack,Fabiano; Baldan,Ana Paula; Fabregat,Thiago El Hadi Perez.
The objective of this work was to evaluate fish oil replacement by soybean oil in diets, as for the effects on the performance and body composition of juveniles of fat snook (Centropomus parallelus). The experiment was carried out in a randomized block design, with three treatments (lipid sources) and six replicates, in a 60-day period. Fat snook juveniles (24.17±0.28g) were distributed in 18 experimental tanks of 200 L each, equipped with aeration and heating systems, under continuous water renovation (800% per day). Three isoproteic (44% CP) and isoenergetic (4,635 kcal CE kg-1) diets were formulated to comprise three replacement rates (0, 50, and 100%) of fish oil by soybean oil. Biometric analyses were done to evaluate fish performance, and two entire...

The feeding habits of the endemic Remo flounder, Oncopterus darwinii (Actinopterygii: Pleuronectidae), in an exposed sandy beach’s surf zone in southern Brazil
Provedor de dados: 103
Autores: Lameiro,Fábio R.; Condini,Mario V.; Brito,Cíntia P.; Vieira,João P.
ABSTRACT The Remo flounder, Oncopterus darwinii Steindachner, 1874 is a small Pleuronectidae (~ 250 mm TL) distributed in the warm-temperate zone from Santa Catarina (28°S - Brazil) to the Gulf of San Matías (42°S - Argentina). We studied the occurrence and diet of juveniles of this flatfish (85% &lt; 100 mm TL) for one year (August 2009 to July 2010) in a southern Brazilian sandy beach. Individuals were much more common in spring and early summer than in the other seasons. Of the 758 individuals analyzed, only 69 (9.1%) were found with empty stomachs. The Remo flounder fed predominantly on small crustaceans (gammarid amphipods, mysids and the hipiidae Emerita brasiliensis Schmitt, 1935) and no seasonal differences were found in the composition of the diet...

Genotoxic effects of the diesel water-soluble fraction on the seahorse Hippocampus reidi (Teleostei: Syngnathidae) during acute exposure
Provedor de dados: 103
Autores: Santos,Celina Alcoforado; Novaes,Larissa Simões; Gomes,Levy Carvalho.
The high toxicity of diesel components makes oil spills a threat to the biota in coastal marine environments. The genotoxic effect of the diesel water-soluble fraction (DWSF) on Hippocampus reidi (Ginsburg, 1933) was assessed. Fish were exposed to three different DWSF dilutions for up to 96 hours, and genotoxicity was analyzed using the micronuclei test and the comet assay. The micronuclei test revealed no significant differences between any of the DWSF dilutions and the control in the 24-hours period; however, micronuclei increased in fish exposed to 1:500 and 1:100 DWSF dilutions for 96 hours. For all dilutions, there was an increase in micronuclei in fish exposed for 96 hours when compared to those exposed for 24 hours. The tested dilutions increased...

A new species of Tormopsolus (Digenea: Acanthocolpidae) parasite of Genypterus brasiliensis (Teleostei: Ophidiidae) from the Brazilian coast
Provedor de dados: 103
Autores: Knoff,Marcelo; Fernandes,Berenice M. M.
Tormopsolus brasiliensis sp. nov. is described from the intestine of Genypterus brasiliensis Regan, 1903, from Brazil. The new species is characterized mainly by having an almost square terminal oral sucker, a pharynx of the same size or larger than the oral sucker, and testes very close to each other and without vitelline follicles between them. Tormopsolus brasiliensis sp. nov. is most closely related to T. lintoni Caballero, 1952, sharing with the latter the space between the gonads and the distribution of the vitelline fields. It differs from that species by the lack of a space between the gonads and the absence of vitelline follicles between the testes; by the smaller distance between the oral and ventral suckers; by the presence of a wide ejaculatory...

Sex control in fish is a promising technique for aquaculture, since it gives advantages associated with one sex. The aim of this study was to investigate the feminization of common snook (Centropomus undecimalis) by oral administration of two doses of estradiol-17β (50 and 100 mg E2 kg-1 feed) and control treatment for 45 days and to evaluate their effects on the sex ratio, growth and survival of common snook juveniles. After this period, fish were fed only with commercial feed without hormone supplementation. During the period of E2 administration, the control fish grew more than those in the other treatments. At the end of the experiment in the treatment with 50 mg E2 kg-1, 26.32% of the fish were male, 68.42% were female, and 5.26% were intersex. In the...

ABSTRACT Parasitic isopods of fishes usually show wide distribution and low host specificity. This study investigated the occurrence of gill parasites in 120 specimens of spotted goatfish Pseudupeneus maculatus, marine fish of great economic importance for fishery community. The fish were captured monthly in the Coast of Pernambuco State, Northeast Brazil, between October 2012 and September 2013. Eleven isopods were found and identified as Rocinela signata. We observed lower infections in the gills of P. maculatus (prevalence 8.3%, mean intensity 1.6±0.3 and mean abundance 0.1±0.3) when compared to other studies of different host fishes from geographically close locations. This parasite has been reported from a wide variety of fish species, not only in...

Ecological aspects of the surf-zone ichthyofauna of Itamambuca Beach, Ubatuba, SP
Provedor de dados: 49
Autores: Gondolo,Guilherme Fernandez; Mattox,George Mendes Taliaferro; Cunningham,Patricia Teresa Monteiro.
Sandy beaches are among the most extensive environments in Brazil and are generally threatened by disorderly urban growth due to their location along the coast, where human populations tend to concentrate. This is especially true in southeastern Brazil, where the largest urban areas are located. Thus, better knowledge regarding these natural resources is of considerable importance. The surf zone of sandy beaches is inhabited by a number of fish species, including juveniles seeking both food and shelter from predators. An ecological survey was conducted in the surf zone of Itamambuca beach in the city of Ubatuba, São Paulo State, Brazil, in order to evaluate the composition, structure and dynamics of the fish fauna using community descriptors.
