| Pseudoplatystoma punctifer is an Amazonian catfish highly appreciated for its high flesh quality, size, and commercial value. Its aquaculture is pursued to satisfy the demands of an increasing population in the region. However, knowledge of the nutritional needs during the early life stages is necessary for improving growth and reducing the incidence of cannibalism, factors that limit the success of its commercial farming. This study aimed at evaluating the influence of four diets containing different protein and lipid levels (30:15, 30:10, 45:15, or 45:10 in %) in the digestive physiology and performance of early juveniles. The results showed that the dietary protein:lipid as well as carbohydrate levels and ratios influenced differently the whole-body... |

| Le bilan du suivi des élevages de moules sur filières montre l'évolution de cette nouvelle pratique culturale en Bretagne et met en évidence les difficultés qui demeurent un frein au développement et à l'extension de ce type d'élevage. Il s'agit en particulier de l'influence du milieu pour certains sites (contamination par le "Dinophysis"), de problèmes biologiques et surtout d'ordre pathologique, liés à de fortes infestations des moules par un vers parasite de la famille des trématodes et responsable de mortalités élevées pour les secteurs Sud-Bretagne. Le choix de l'espèce se précise : les producteurs se tournent vers l'élevage de la moule locale captée naturellement sur les installations. Celle-ci a une meilleure tenue sur les supports et à la... |

| Teleost fish are more diverse than any other vertebrate group, and yet only a limited number of species are fished and farmed globally. Efforts to expand the quantity and diversity of fish produced are hampered by the extreme diversity of ontogenetic responses of fish, especially during larval development. This review looks at advances in molecular phylogeny, endocrine and nutrient influences and long-term studies of the phenotypes of commercially important fish to put the sources and consequences of this plasticity into context. This nested context of evolutionary forces of the fish-specific genome duplication, epigenetic influences, ontogenetically conserved processes like metamorphosis and cell determination is further presented in relation to how fish... |

| Dispersal and colonisation processes at deep-sea vents are still not fully understood, essentially because early life stages of vent species remain unknown. The polychaete worm Alvinella pompejana forms colonies on chimney walls at East Pacific Rise vent sites where the temperature can frequently exceed 20 degrees C. In vitro studies in pressure vessels showed that the early embryos tolerate temperatures in a lower range (10-14 degrees C), suggesting that they would have to escape the colony to develop. Pressure vessels offer the advantage that each parameter can be independently controlled, but they do not simulate the more complex and dynamic conditions naturally encountered at vent sites. Accordingly, in addition to incubations in pressure vessels, we... |

| Members of the Transforming Growth factor beta (TGF-beta) superfamily of cell signalling polypeptides are known to play important roles in cell proliferation and differentiation during development and in various physiological processes of most animal clades. Recent findings in the mollusc Crassostrea gigas demonstrate the occurrence of a diversity of TGF-beta signalling components including various ligands, three type I receptors but only a single type II receptor. This report describes the characterization of Cg-ActRII, a new type II receptor displaying homology with vertebrate and Drosophila Activin type II receptors. The use of zebrafish embryo as a reporter organism revealed that, in a way similar to its zebrafish counterpart, overexpression of... |

| The oyster vasa-like gene was previously demonstrated to be specifically expressed in germline cells of adult oysters Crassostrea gigas. In the present study, this gene was used as a molecular marker to establish the developmental pattern of germline cells during oyster ontogenesis. using whole-mount in situ hybridization and real-time PCR. The Oyvlg transcripts appeared to be localized to the vegetal pole of unfertilized oocytes and maternally transmitted to embryos. At early development, these maternal transcripts were observed to segregate into a single blastomere, from the CD macromere of 2-cell stage to the 4d mesentoblast of blastula. From late blastula stage, the mesentoblast divided into two cell clumps that migrated to both sides of the larvae... |

| Air‐breathing and amphibious fishes are essential study organisms to shed insight into the required physiological shifts that supported the full transition from aquatic water‐breathing fishes to terrestrial air‐breathing tetrapods. While the origin of air‐breathing in the evolutionary history of the tetrapods has received considerable focus, much less is known about the evolutionary physiology of air‐breathing among fishes. This review summarises recent advances within the field with specific emphasis on the cardiorespiratory regulation associated with air‐breathing and terrestrial excursions, and how respiratory physiology of these living transitional forms are affected by development and personality. Finally, we provide a detailed and re‐evaluated model... |

| France is presently one of the leading countries in Europe for shellfish production with 152,000 metric tonnes of the Pacific cupped oyster C. gigas, 2,500 tonnes of flat oyster O. edulis, and more than 60,000 tonnes of mussels M. edulis and M. galloprovincialis. Moreover, species like the pearl oyster Pinctada margaritifera in French Polynesia, and on the Atlantic coastline the scallop Pecten maximus and the Manila clam Tapes philippinarum contribute significantly to the overall landings. . Since traditional rearing areas are now almost overloaded, new management practices are currently under review to optimise and develop shellfish culture. Besides the products resulting from genetic research (e.g. triploids, tetraploids and disease resistant strains),... |

| The aim of this study was to determine whether mortality observed during the larval development of reared bluefin tuna (Thunnus thynnus) could be related to improper expression profiles of key genes involved in digestive or antioxidant response capabilities. Tuna larvae were sampled at hatching, 2, 5, 10, 15 and 20 dph (days post hatching) for the relative quantification of transcripts encoded by genes involved in digestive [trypsinogen 1 (TRYP1), alpha-amylase (AMY), aminopeptidase N (ANPEP)] and antioxidant [catalase (CAT)] functions. The levels of expression of ANPEP related to the development and maturation of intestinal function increased from 5 to 20 dph. Furthermore, AMY and TRYP1 genes, which are pancreatic enzymes implicated in carbohydrate and... |

| During the larval period, marine teleosts undergo very fast growth and dramatic changes in morphology, metabolism, and behavior to accomplish their metamorphosis into juvenile fish. Regulation of gene expression is widely thought to be a key mechanism underlying the management of the biological processes required for harmonious development over this phase of life. To provide an overall analysis of gene expression in the whole body during sea bass larval development, we monitored the expression of 6,626 distinct genes at 10 different points in time between 7 and 43 days post-hatching (dph) by using heterologous hybridization of a rainbow trout cDNA microarray. The differentially expressed genes (n = 485) could be grouped into two categories: genes that were... |

| Background: The Pacific oyster, Crassostrea gigas, is one of the most important aquaculture shellfish resources worldwide. Important efforts have been undertaken towards a better knowledge of its genome and transcriptome, which makes now C. gigas becoming a model organism among lophotrochozoans, the under-described sister clade of ecdysozoans within protostomes. These massive sequencing efforts offer the opportunity to assemble gene expression data and make such resource accessible and exploitable for the scientific community. Therefore, we undertook this assembly into an up-to-date publicly available transcriptome database: the GigaTON (Gigas TranscriptOme pipeliNe) database. Description: We assembled 2204 million sequences obtained from 114 publicly... |

| The European abalone Haliotis tuberculata is a delicacy and consequently a commercially valuable gastropod species. Aquaculture production and wild populations are subjected to multiple climate-associated stressors and anthropogenic pressures, including rising sea-surface temperatures, ocean acidification and an emerging pathogenic Vibrio infection. Transcript expression data provides a valuable resource for understanding abalone responses to variation in the biotic and abiotic environment. To generate an extensive transcriptome, we performed next-generation sequencing of RNA on larvae exposed to temperature and pH variation and on haemolymph of adults from two wild populations after experimental infection with Vibrio harveyi. We obtained more than 1.5... |

| This paper is aimed at analysing the similar trends and different constraints which influence marine fish farming of new species such as sea-bass, sea-bream and turbot in Europe in comparison with the Norwegian salmon farming success. In a general context of low progression, European aquaculture has been characterised by the development of intensive fish farming. The most notable fact is the recent increase in intensive salmonid farming, with a turnover of almost 2 millions 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. Turbot farming is developing slowly too on the French and Spanish Atlantic coast, taking benefit of the temperate climate in... |

| Mussels within the subfamily Bathymodiolinae, in particular the larger Bathymodiolus species (sensu lato) thriving at cold seeps and hydrothermal vents, are among the most iconic fauna to colonize deep-sea reducing habitats globally. Fuelled by energy derived from chemosynthetic symbioses, their contribution to ecosystem productivity is conspicuous, with many bathymodioline species forming dense, extensive aggregates. Chemosymbiotic mussels play crucial roles as ecosystem engineers, both through the formation of spatially heterogeneous biogenic reefs and in redistributing reduced-fluid emissions. The notable absence of Bathymodiolinae outside of reducing ecosystems affirms their dependency on these ephemeral habitats, placing spatiotemporal constraints on... |
