Résumé : Ensuring the sustainability of fish resources necessitates understanding their interaction with coastal habitats, which is becoming ever more challenging in the context of ever increasing anthropogenic pressures. The ability of coastal lagoons, exposed to major sources of disturbance, to provide resources and suitable habitats for growth and survival of juvenile fish is especially important. We analysed three lagoons with different ecological statuses and habitat quality on the basis of their eutrophication and ecotoxicity (Trix test) levels. Fish abundances were sampled using fishing and horizontal beaming acoustic surveys with the same protocols in the same year. The relative abundance of Anguilla anguilla, Dicentrarchus labrax or the Mugilidae group was not an indicator of habitat quality, whereas Atherina boyeri and Sparus aurata appeared to be more sensitive to habitat quality. Fish abundance was higher in the two lagoons with high eutrophication and ecotoxicity levels than in the less impacted lagoon, while fish sizes were significantly higher in the two most severely impacted lagoons. This leads us to suggest low habitat quality may increase fish growth rate (by the mean of a cascading effect), but may reduce lagoon juvenile abundance by increasing larval mortality. Such a hypothesis needs to be further validated using greater investigations which take into account more influences on fish growth and recruitment in such variable environments under complex multi-stressor conditions.

Résumé : The aquaculture of Macrobrachium rosenbergii is launched in Martinigue by the regional council in 1976. A first "green water" type hatchery is built and provides juveniles to the first ponds. In 1978, CNEXO is asked to cooperate in scientific assistance. A new hatchery is built with COP "clear water" system and produces in 1980. The development of ponds (20 ha) needs the increase of the hatcheries capacity, which is now done with one single method and intensive larval first stage (7-8 millions PL. cap). In Guadeloupe, the first ponds started in 1978. Two cooperatives and 11 ha of ponds at this time have determined the construction of CNEXO in the construction of a regional hatchery. A small light one is already under production since July 83.
L'aquaculture du Macrobrachium rosenbergii débute en Martinique en 1976 à l'initiative du Conseil Rëgional7~0ne premiere écloserie type "eau verte" est construite et ensemence les premiers bassins. En 1978, le CNEXO est sollicité pour apporter son concours scientifique qui se traduit par la construction d'une seconde écloserie type COP "eau claire", opérationnelle en 1980. Le développement des bassins (20 ha) entraîne celui des écloseries, unifiées en 1983 par une méthode unique enrichie d'un prégrossissement larvaire permettant une capacité de 7 à 8 millions de PL.. En Guadeloupe, le développement des premiers bassins date de 1978. Les deux coopératives actuelles et les 11 ha de bassins ont entraîné l'apparition de 2 écloseries privées et, après accord de toutes les parties, l'intervention du CNEXO pour la construction d'une écloserie à vocation régionale précédée d'une petite écloserie provisoire en fonctionnement depuis juillet 1983.

Résumé : International audience
Growth series of Palaeozoic fishes are rare because of the fragility of larval and juvenile specimens owing to their weak mineralisation and the scarcity of articulated specimens. This rarity makes it difficult to describe early vertebrate growth patterns and processes in extinct taxa. Indeed, only a few growth series of complete Palaeozoic fishes are available; however, they allow the growth of isolated elements to be described and individual growth from these isolated elements to be inferred. In addition, isolated and in situ scales are generally abundant and well-preserved, and bring information on (1) their morphology and structure relevant to phylogenetic relationships and (2) individual growth patterns and processes relative to species ontogeny. The Late Devonian acanthodian Triazeugacanthus affinis from the Miguasha Fossil-Lagerstä tte preserves one of the best known fossilised ontogenies of early vertebrates because of the exceptional preservation, the large size range, and the abundance of complete specimens. Here, we present morphological, histological, and chemical data on scales from juvenile and adult specimens (scales not being formed in lar-vae). Histologically, Triazeugacanthus scales are composed of a basal layer of acellular bone housing Sharpey's fibers, a mid-layer of mesodentine, and a superficial layer of ganoine. Developmentally, scales grow first through concentric addition of mesodentine and bone around a central primordium and then through superposition of ganoine layers. Onto-genetically, scales form first in the region below the dorsal fin spine, then squamation spreads anteriorly and posteriorly, and on fin webs. Phylogenetically, Triazeugacanthus scales show similarities with acanthodians (e.g. " box-in-box " growth), chondrichthyans (e.g. squamation pattern), and actinopterygians (e.g. ganoine). Scale histology and growth are interpreted in the light of a new phylogenetic analysis of gnathostomes supporting acantho-dians as stem chondrichthyans.

Résumé : These first results might clarify some problems linked to the biology of tarets and other small lignivorous crustaceans. The systematic of the molluscs Teredinidae, so complex, is only based on the study of pallets, which is a great source of confusion when one has to examine the woods after the molluscs' death. We tried to distinguish the species by examining the striates and denticulations on the shelves. The size of the intervals between the striates and the proportional size of the denticulations, as well as the shape of the denticulation marks of the middle part, can indeed allow us to differentiate between some species. [...]
Ces premiers résultats pourront peut-être jeter quelque clarté sur les problèmes se rapportant à la biologie des tarets et des petits crustacés lignivores. La systématique des mollusques Teredinides, si complexe, a été fondée uniquement sur l'examen des palettes, ce qui est une source de confusion lorsqu'on est obligé, ce qui est le cas le plus fréquent, d'examiner les bois après la mort des mollusques. Nous avons cherché à distinguer les espèces par les stries et les denticulations visibles sur les coquilles. Les dimensions des intervalles séparant les stries et la taille proportionnelle des denticulations, ainsi que la forme de l'empreinte des denticulations de la partie moyenne peuvent différencier, effectivement, quelques espèces. C'est ainsi que Teredo pedicellata et Teredo navalis sont immédiatement distingués à l'examen des stries; de même Bankia minima et Bankia badigaensis. Mais il faut, bien entendu, tenir compte des variations individuelles, les denticulations pouvant être plus ou moins fortes chez une même espèce. Il semble difficile d'interpréter tout le comportement des petits crustacés et même des larves de Térédinides par une simple réaction de chimiotropisme : les animaux peuvent choisir un point ou une zone sur le support. Certaines essences, tout au moins au début de leur immersion, semblent jouer un rôle répulsif ou non attractif pour les crustacés: le Hêtre, Kaya ivorensis et Samba; ces observations ne sont valables que pour une saison chaude. Chez les mêmes crustacés, la préférence pour l'ombre joue un rôle très important. (OCR non contrôlé)

Résumé : Deep-sea bivalves of the subfamily Bathymodiolinae (family Mytilidae) are very widespread and form dense beds in reduced environments such as hydrothermal vents and cold seeps. Bathymodiolus mussels recently discovered on African cold seeps strangely resemble Gulf of Mexico and Barbados seep species. This raises intriguing questions regarding their taxonomic relationships and their dispersal capabilities across the Atlantic equatorial belt. The morphological study of the shell and soft parts of mussels from either sites of the Atlantic shows that they form two distinct groups: the Bathymodiolus boomerang group (also including Bathymodiolus heckerae and a species from Africa), and the Bathymodiolus childressi group (also including Bathymodiolus mauritanicus and one species from Barbados). Phylogenetic relationships inferred from the nucleotide sequences of the ribosomal DNA internal transcribed spacer (ITS-2) and mitochondrial cytochrome c oxidase subunit I (COI) confirmed morphological analyses and the existence of two amphi-Atlantic complexes of species. Both ITS2 and COI phylogenies indicate almost no difference between the two eastern Atlantic seep mussels (Bathymodiolus sp. A and B. mauritanicus) and their western Atlantic counterparts (B. boomerang and Bathymodiolus sp. B; Barbados Prism cold seeps). In the B. boomerang complex, B. heckerae seems to differ from the Barbados and the African species, whereas these latter two are not distinguishable. In the B. childressi complex, relationships are less clear and do not support the description of new species from the Barbados. Past and present-day connections across the Atlantic are discussed in the light of both larval dispersal capabilities of the mussels and the equatorial Atlantic circulation to appreciate whether these species could represent true amphi-Atlantic species.

Résumé : To develop shrimp fanning in French Polynesia where no indigenous commercial species of penaeid prawn exists, the first step is to select the right species according to the following criteria: maturation and spawning in captivity, mass production of post-larvae, fast growth at semi-intensive density, acceptability of artificial diet, disease resistance and hardiness. This paper presents the results on P. monodon, Fabricius, the largest Indo-Pacific species. Experiments have been conducted in the "Centre Océanologique du Pacifique" in Tahiti Island where the environmental conditions are water temperature range 25-29 C, salinity 35 ppt, pH 8.2.

Résumé : Le mérou géant, Epinephelus itajara, espèce en danger critique d’extinction au niveau mondial, est présent dans les eaux turbides et saumâtres de la Guyane française où l’espèce est exploitée par une pêcherie côtière. Dans la partie est du plateau continental guyanais, les mérous géants se localisent autour de tous les sites rocheux marins où ils se répartissent en fonction de la profondeur et du faciès (éboulis ou tombant). Les analyses des isotopes stables du carbone et de l’azote suggèrent qu’environ 30 % des mérous géants < 115 cm présents sur ces sites rocheux, proviendraient des mangroves alentours. Les analyses de contenus stomacaux révèlent un changement ontogénétique du régime alimentaire. Les petits individus (< 90 cm) s’alimentent principalement de Crustacés puis intègrent progressivement les poissons à leur alimentation jusqu’à devenir essentiellement piscivores au-delà de 140 cm. La population de Guyane est principalement composée d’individus juvéniles : seulement 8,5 % des individus capturés en Guyane a plus de 6 ans. Ces jeunes mérous sont très territoriaux durant les 4-5 premières années de leur vie puis ne sont plus retrouvés sur les sites rocheux. Le devenir de ces juvéniles est incertain, soit ils sont pêchés, soit ils migrent vers d’autres sites ou vers les agrégations de reproduction. Cependant, les mérous géants ne semblent pas se reproduire en Guyane. Il est possible que les conditions environnementales (forte turbidité et température) ne favorisent pas le développement gonadique, ce qui engendrerait une omission totale de reproduction. Le suivi par tags satellite suggère que les mérous géants migrent dans le sens des courants marins vers Trinidad-et-Tobago, potentiellement pour la reproduction. Aucun mouvement vers le Brésil n’a été mis en évidence bien que les stocks de mérous géants du Brésil et de Guyane semblent liés. En effet, ces deux stocks évoluent conjointement avec un déclin des populations au début des années 90. Le maintien de la population de mérou géant en Guyane se ferait grâce à l’apport de larves des sites d’agrégation du Brésil par le courant marin. La mortalité totale des mérous géants (0,65) est aussi élevée au sein de la réserve marine ainsi que sur les sites de pêche. Cela suggère que l’interdiction de pêche à la réserve n’est pas respectée et que les grands individus quittent la réserve pour des sites plus spacieux. En supposant que la population de mérous géants adultes a été réduite à cause de la pêche, une protection régionale des individus > 150 cm doit être instaurée afin de régénérer le stock d’individus matures. Il semble nécessaire de développer une politique de gestion internationale de l’espèce, surtout entre la Guyane et le Brésil, afin de conserver les populations de mérous géants d’Amérique du Sud.
The critically endangered Goliath Grouper, Epinephelus itajara, is found in the turbid and brackish waters of French Guiana, where the species is subject to a coastal fishery. Goliath Grouper populations inhabit all rocky habitats and exhibit increasing abundance with depth. Around 30% of individuals less than 115 cm may derive from the abundant mangrove habitat along the french Guiana coast. There is a ontogenetic shift of the diet, primarily crustacivorous, individuals >140 cm become piscivorous. The Goliath Grouper population in French Guiana is composed primarily og juvelines. The fate of the juvelines is unknonw, some may be caught in the fishery, others may move to other habitat. No evidence of spawning or gonadal readiness was found in french Guiana. it is possible that environmental conditions (high turbidity and temperature) are not conducive to reproductive activity. Goliath Grouper may migrate down current from French Guiana to Trinidad and Tobago or further. No movement of Goliath Grouper was found against the current toward Brazil. French Guiana juveniles may be derived from spawns occuring off Brazil. Calculated total mortality of Goliath Grouper off French Guiana is high (0.65) in both fished and protected areas suggesting that illegal fishing is occuring within the protected area, or that emigration rates are high. Assuming that the adult population of Goliath Grouper in French Guiana has been reduced due to fishing, protection of spawning-size adults (larger than about 150 cm TL) should be instated.

Résumé : Shrimp and prawn aquaculture is developing fast and amounts presently to 8% of world consumption. It concerns mainly various species of penaeids and is done with different techniques where feeding plays a variable role. This role is discussed both in the case of more or less extensive farming and in the case of intensive farming. The lack of knowledge in the field of nutrition itself is emphasized as well as the importance of feed technology both for juvenile foods and larval microcapsules or microparticles.

Résumé : Macrobrachium rosenbergii nodavirus (MrNV) and extra small virus (XSV) were purified from diseased freshwater prawns M rosenbergii and used to infect healthy post-larvae (PL) by an immersion method. Three groups of prawns were challenged with various combined doses of MrNV and XSV. Signs of white-tail disease (WTD) were observed in Groups 1 and 2, which had been challenged with combinations containing relatively high proportions of MrNV and low proportions of XSV. By contrast there was little sign of WTD in Group 3, which had been challenged with a higher proportion of XSV than MrNV. A 2-step Taqman real-time RT-PCR was developed and applied to quantify viral copy numbers in each challenged PL. Results showed that genomic copies of both viruses were much higher in Groups 1 and 2 than they were in Group 3, indicating that MrNV plays a key role in WTD of M rosenbergii. The linear correlation between MrNV and XSV genome copies in infected prawns demonstrated that XSV is a satellite virus, dependent on MrNV, but its role in pathogenicity of WTD remains unclear.

Résumé : In New Caledonia, there is no indigenous shrimp species for commercial aquaculture and it is necessary to control the complete cycle in captivity. Since 1973 and the creation of the Station d'Aquaculture de Saint-Vincent (S.A.S.V.), a joint project between IFREMER, France-Aquaculture and the territory of New Caledonia, nine species have been tested and for one of these, P. stylirostris , (introduced in 1980), we are now in a commercial scale production with the tenth generation obtained in captivity.

Résumé : Shrimp farming is a small but growing industry in New Caledonia. Since 1993, "Syndrome 93" has been affecting New Caledonian shrimp farming industry every cold season, causing severe epizootic mortalities in grow-out ponds and significant losses. Highly pathogenic strains of Vibrio penaeicida are considered the etiological agent of the disease in Litopenaeus stylirostris. On one hand, studies demonstrated that healthy shrimp may carry V penaeicida for weeks with a high overall prevalence, regardless of any seasonal pattern or temperature conditions. On the other hand, larvae are free of V penaeicida and are also resistant to experimental infection. V penaeicida is frequently detected in incoming water pumped from the bays, which was shown, by a molecular typing study, to be the infectious source. This particular epidemiological pattern highlights the major role of the factors that trigger and aggravate the disease in grow-out ponds, where shrimp populations carry the pathogen all year round. In order to gain a better understanding of "Syndrome 93" epidemiology, quantification of V penaeicida both in shrimp and the shrimp farm ecosystem is necessary. This article describes the steps in the successful development of a real-time PCR quantification assay of V penaeicida in shrimp haemolymph, seawater (from ponds or bays) and sediment pore water, including the choice of an accurate extraction technique. The entire detection method; including sample processing, DNA extraction and real-time PCR amplification, can be completed within 4 h. (c) 2006 Elsevier B.V All rights reserved.

Résumé : Spatio-seasonal explicit simulation models can predict the impact of spatial management measures on marine fish populations and fishing activities. As fisheries are complex systems, fisheries simulation models are often complex, with many uncertain parameters. Here, the methodology is provided to deliver fishery diagnostics within an uncertainty context using a complex simulation tool. A sensitivity analysis of the model is performed on model outputs using partial least-squares to identify the most sensitive parameters. The impact of several management measures is then simulated using a statistical simulation design taking into account the uncertainty of the selected sensitive parameters. This approach was applied to the Bay of Biscay anchovy stock using the ISIS-Fish (Integration of Spatial Information for Simulation of Fisheries) model to assess the impact of imposing marine protected areas (MPAs) conditionally on parameter uncertainty. The diagnostic appeared to be highly sensitive to the mortality of larvae and juveniles, growth, and reproduction. The uncertainty of the values of these parameters did not permit any of the simulated MPA designs to be proposed. However, according to anchovy catch and biomass, the simulations allowed the low impact of closure duration to be shown and underscored the utility of protecting such key processes as spawning.

Résumé : Vibriosis is a major disease problem in shrimp aquaculture, affecting all developmental stages, from larvae in hatchery tanks to juveniles and broodstock in growout ponds. However, bacterial strains responsible for vibriosis in the successive stages are usually considered to be different, and virulence specificity has been reported both at the species and at the stage levels. The so-called « Syndrome 93 » is a seasonal juvenile vibriosis caused by Vibrio penaeicida which affects Penaeus stylirostris in growout ponds and broodstock tanks in New Caledonia. This pathology does not cause any mortality in hatchery or nursery phases. An experimental infection design using balneation of postlarvae and early juveniles in V. penaeicida suspensions was used to evaluate the developmental stage at which shrimp become sensitive to this vibriosis. We demonstrated that the acquisition of susceptibility to this pathogen is very sudden and correlated with the acquisition of the definitive rostral formula, and from this draw conclusions regarding virulence mechanisms of V. penaeicida in P. stylirostris.

Résumé : Centropomidae and Serranidae, sometimes collectively misnamed "sea basses", are suitable for aquaculture in pens, ponds, and raceways around the tropical and subtropical latitudes of the world. Western Atlantic Ocean species were recently considered for farming. South Florida, Mexico, Central and South America and the Antilles areas of the Caribbean Basin have extensive areas suitable for farming groupers and snook. Principal species of interest are the common snook (Centropomus undecimalis ), the fat snook (C. parallelus ), the Nassau grouper (Epinephelus striatus ), Black seabass (Centropristis striatus ), Gag (Mycteroperca microlepis ), and jewfish (E. itajara ).

Résumé : Tahiti’s pearl farming industry plays a major socio-economic role in French Polynesia. In an increasingly competitive market where the production of high quality pearls becomes essential, research can help secure and ensure sustainable production. In that context, Ifremer, in close collaboration with the “direction des resources marines” (French Polynesian government agency) has developed research projects on the “sustainable development of pearl farming”. This program is organized along 3 axes: (1) understanding the animal physiology and initiating a genetically selective breeding program of donor oysters; (2) understanding pearl oyster larvae dispersal and recruitment; (3) understanding the molecular mechanisms underlying biomineralization processes during shell and pearl formation. It is in this frame that we have developed a highthroughput Expressed Sequence Tags pyrosequencing program on the calcifying mantle, combined with proteomic analyses of the shell and pearl. We analyzed 276738 EST sequences, leading to the constitution of a P. margaritifera mantle transcripts catalogue of 82 sequences potentially involved in biomineralization. Our results provided direct evidence that our ESTs data set covers a large number of the matrix proteins of P. margaritifera. In addition, our proteomic analysis enabled us to retrieve, in silico, all the sequences from P. margaritifera involved in the biomineralization process already published on databases. Integration of these two methods allowed, for the first time, the global composition of calcifying tissue and calcified structures to be examined in tandem.
