| En 1996, le vieillissement des fonds de bassins aquacoles de crevettes était présenté comme hypothèse explicative de la dégradation des rendements de production sur certains sites d’élevage. Un travail conséquent avait été réalisé à l’époque dont l'objectif était, à partir d'un inventaire des différents sédiments des fermes aquacoles du Territoire, de mettre en évidence une éventuelle évolution de ce sédiment au fil des cycles d'élevage et son influence sur la productivité. L’objet de ce document est de numériser et de compiler les différentes fiches techniques diffusées à l’époque sous forme papier aux aquaculteurs de la filière crevette de Nouvelle-Calédonie. |

| This book represents a two year study by a team of French biologists to collect, summarise and present the experience and knowledge gained in the rearing of the giant freshwater prawn, not only in the French overseas territories but also in the main countries which are developing this culture. This document comprises four parts : - The first describes the world market. The prawn rearing is already an economic reality in the tropical world, the United States and in Europe. - The second on shows that, although the culture techniques are quite complex, production systems can be adapted to local conditions and markets. - The third part is a practical guide, both for investors and farmers, giving all necessary data to start-up and monitor a project in the... |

| When facing the increasing development of aquaculture, farming in recycled water is an alternative to limit the impact on the environment: farming produces a lower amount of wastes but of higher concentration which can be treated. The goal of this thesis is to evaluate the efficiency of high rate algal lagooning/ponding (HRAP) for the treatment of marine fish culture effluents. Also, this study utilizes wastes from Dicentrarchus labrax grown in Ifremer's recycled waters station. The first step shows the particularities linked to recycled water farming effluents. They are characterized by low particle and organic substance concentrations as well as strong dissolved inorganic nitrogen (DIN) and phosphorus (DIP) concentrations. Furthermore, nitrogen is mainly... |

| Four replicated groups of sea bass (Dicentrarchus labrax) larvae were fed diets containing an extra-high level of highly unsaturated fatty acids (HUFA) (XH; 3.7% EPA + DHA), a high level of HUFA (HH; 1.7%), a low level of HUFA (LH: 0.7%) or an extra-low level of HUFA (XLH; 0.5%) from day 6 to day 45 (experiment 1; XH1, HH1, LH1, XLH1). After a subsequent I-month period feeding a commercial diet (2.7% EPA + DRA), the capacity of the four initial groups to adapt to an n-3 HUFA-restricted diet (0-3% EPA + DHA; R-groups: XH2(R), HH2(R), LH2R, XLH2(R)) was tested for 35 d. Larval dietary treatments had no effect on larval and juvenile survival rates. The wet weight of day 45 larvae was higher in XH1 and HH1 (P<0.001), but the R-juvenile mass gains were... |

| Recirculation of the water of fish rearing systems requires a biological treatment based on the nitrifying activity of autotrophic bacteria. In parallel heterotrophic bacterial populations utilise the organic substrate, produced by the fish, to grow. Opposite to the autotrophic populations, the heterotrophic bacteria (1) have a quick growth and (2) might contain fish pathogenic strains. The main aim was to characterise the heterotrophic bacteria populations ?.nd to understand (1) which parameters do control the dynamics of their populations and (2) their influence on the quality of the recirculating water. In a rearing system, the heterotrophic bacterial populations are stable in number and in genus, for a given operating mode. The bacteria are either... |

| Background Fully isogenic lines in fish can be developed using “mitotic” gynogenesis (suppression of first zygotic mitosis following inactivation of the sperm genome). However, genome-wide verification of the steps in this process has seldom been applied. We used ddRADseq to generate SNP markers in a meiotic gynogenetic family of European seabass (Dicentrarchus labrax): (i) to verify the lack of paternal contribution in a meiotic gynogenetic family; (ii) to generate a gene-centromere map from this family; (iii) to identify telomeric markers that could distinguish mitotic gynogenetics from meiotic gynogenetics, which sometimes arise spontaneously in mitotic gynogenetic families. Results From a single meiotic gynogenetic family consisting of 79 progeny, 42... |

| The new sustainable development data repository requires new analysis grids, in particular for factors accounted for in productive system typologies. This paper, based on the aquaculture example, analyses the diversity in aquaculture systems with respect to sustainable development. Various typologies are obtained by evaluating structural and functional approaches integrating variables related to production and regulation systems and to the territorial insertion of fish farms. Categories have been defined on a scale based on a set of five sites, which are representative of a wider range of aquaculture systems. Use of these categories goes beyond the local typologies and prepares a generic meta-typology classification for the systems. This generic... |

| A natural endowment of three coast lines with different structures, of numerous rivers coming from mountainous regions and of different climatic conditions has enabled France to develop one of the first European aquaculture sectors in terms of volume with almost 300 000 tonnes in 1996. This development has been based on a wide range of species and on a wide range of techniques. Intensive marine fish farming has been developing during the last decade only, after many years of stagnation due to the lack of reliable technology for species adapted to French climate. Techniques of production are very diverse. Although earth ponds and race-ways are used only by 25% of the marine fish farms, this technique accounts for 40% of the production. On the contrary, many... |

| Le congrès annuel de l'EAS (European Aquaculture Society) a rassemblé pendant 4 jours 531 chercheurs, producteurs et responsables institutionnels de 47 nationalités. Il a donné lieu à la présentation de 105 communications orales et de 274 posters. La thématique générale du congrès était construite sur le thème général suivant: Biotechnologies for quality. Il s'agissait de montrer que les biotechnologies, qui font parfois peur au consommateur comme au citoyen, constituent un outil privilégié de développement de l'aquaculture, y compris dans les aspects de développement durable. De fait, aujourd'hui, les attentes du grand public restent centrées autour des notions de qualité, sécurité, bien-être et santé animale. Le représentant de la Commission européenne a... |

| Une étude du milieu de cinq bassins d'élevage a été menée du point de vue de la qualité de l'eau (température, salinité, oxygène dissous, pH, chlorophylle A, nutriments) et de la qualité du sédiment (matière organique, carbonate de calcium, épaisseur de vase organique, macrofaune dominante). La salinité, contrairement à la température, est fonction de la fréquence et du mode de renouvellement. Les variations nocturnes du pH de l'eau sont en relation avec celles de l'oxygène dissous qui sont elles-mêmes fonction de la concentration en chlorophylle a. La fluctuation du pH de la colonne d'eau differe selon les bassins. Elle peut être stable (autour de 8,1) ou très variable (entre 7,6 et 8,6), sans être toujours en relation avec la concentration en... |

| Genetic parameters of production traits (growth, carcass yield, fillet yield) and bony tissues (head and vertebral axis) were estimated for large all-female rainbow trout Oncorhynchus mykiss reared in freshwater. Genetic parameters were estimated using REML at 16 months of age (1636 g) on 1962 DNA-assigned progenies from a partial factorial mating design with 60 dams and 100 sex-reversed sires. Most traits presented medium to high heritability (0.37 to 0.54). A high genetic correlation (r(A)=0.97) was found between fillet yield and headless gutted carcass yield (or HGCarc%). Due to its higher heritability and high genetic correlation with fillet yield, selection on HGCarc% should result in a 50% increase in selection efficiency on fillet yield by reducing... |

| Algae are utilized diversely in aquaculture, but their main applications are related to nutrition. They are used in toto, as a sole component or as a food additive to supply basic nutrients, color the flesh of salmonids or for other biological activities. The need for nutritional sources safer than traditional animal products has renewed interest in plants in general and algae in particular. This report deals principally with the nutritional role of microalgae in aquaculture.The larvae of molluscs, echinoderms and crustaceans as well as the live prey of some fish larvae feed on microalgae. Though attempts have been made to substitute inert particles for these micro-organisms which are difficult to produce, concentrate and store, only shrimp and live prey... |

| The purpose of this study was to check if it is possible to influence sea bass juvenile metabolism by a conditioning of larvae from day 6 post hatching to day 45 to a low or a high HUFA compound diet (LH, 0.8% EPA + DHA and HH, 2.2% EPA + DHA) when reared at 16 or 22 °C. Following a 3-month intermediate period (at 19 °C using a commercial diet), the adaptability of the 4 initial larval groups to a HUFA experimental deprived diet (0.5% EPA + DHA) were tested at 19 °C in a 60 day-experiment (d-151211). The four experimental duplicated conditions were ex-LH16 and ex-HH16 for the 2 groups previously reared at 16 °C (initial weight, 7.3 ± 0.5 g) and ex-LH22 and ex-HH22 for the 2 groups previously reared at 22 °C (initial weight, 11.1 ± 0.5 g). Survival was... |

| 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... |

| The intertidal zone is characterized by a sharp vertical gradient of environmental stress, which structures species distribution and their interactions. Few studies, however, have examined the influence of tidal height on host–pathogen interactions. Here, we investigated how the tidal height influence outbreak of the Ostreid herpesvirus type 1 (OsHV-1) affecting the Pacific oyster. A volunteer network composed of 20 oyster growers monitored the survival of 28 batches of oysters during an epizootic event in Southern Brittany, France. Oysters were spat from wild collection or hatchery production. The sampling sites were spread over a 150-km2 area with a tidal height ranging from 0.98 to 2.90 m. Concomitantly, we followed survival of oyster spats in relation... |
