| Fishing and trade of living crustaceans are dynamic commercial sectors in France. 25 000 tons of local or imported crabs, lobsters , crawsfishes are yearly treated. Based upon a literature review and fishmongers interviews, this study describes the current pratices and problems associated to live crabs and lobsters storage. Supply conditions of live crustaceans, marketing networks, and biological, ecological and physiological characteristics of crustaceans were discussed. Morever, storage facilities, their operating rules and factors affecting the survival rate under storage and transportation conditions were reviewed. |

| Massive abnormal mortalities of flat oysters Crassostrea during the summer period are nothing new, and such episodes have been described in scientific literature for about forty years. Numerous studies demonstrate that there is not one single identified cause to this phenomenon and that it is, on the contrary, a combination of different parameters. This program proposes a multidisciplinary approach to the problem of summer mortality of C. gigas in which the working hypothesis is that these mortalities result from the interaction of three parameters: environment, host and pathogens. As a consequence, this program gathers all the necessary competences for the study of these interactions: competences in genetics, physiology, immunology, ecotoxicology,... |

| The bacteria of the Vibrio genus are one of the most abundant groups in the aquatic ecosystems. Two species of vibrios, Vibrio splendidus and V. Aestuarianus, have been associated, in some cases, to mortality in flat oyster Crassostrea gigas farms, most of the time during the summer period. This doctoral thesis studies the Vibrio-host interaction and their modulations according to the host's pathogenic virulence and its genetic, physiologic and immunitary parameters. These factors will be characterised by in vitro and in vivo approaches (experimental infection). The characterization of contrasted genetic families according to their sensitivity to these vibrios will enable the implementation of new improvement strategies in oyster farms (prophylactic... |

| L'huître appartient à l'embranchement des mollusques, classe des pélécypodes ou lamellibranches, ordre de monomyaires, famille des ostréidés. Les multiples espèces, vivant actuellement dans le monde, il y en a une centaine environ, différent en particulier par la forme variable de leur coquille et par quelques détails de leur organisation interne. Les récentes études des coquilles larvaires, présentant dans leur charnière crénelée des différences remarquables, on permis de déterminer trois genres dans la famille des ostréidés : le genre Ostrea, le genre Gryphaea et le genre Pycnodonta. Sur les côtes françaises, deux espèces sont rencontrées et font l'objet de culture. Ce sont : Ostrea edulis, l'huître plate, et Gryphaea angulata, l'huître portugaise. Le... |

| The cupped oyster, Crassostrea gigas was first introduced in France in 1967 [13]. On the Atlantic coast, the Marennes Oléron Bay (Figure 1) is the first European oyster culture basin with a cupped oyster (Crassostrea gigas) stock of 110,000 tons and an annual output of 30,000 to 40,000 tons. The Ronce oyster bank, located at the south of the bay (Figure 1), is made of 1,600 concessions spread out over 175 ha. It produces 8,000 to 10,000 tons of cupped oysters each year. In Japan, Crassostrea gigas has been cultivated for more than 1,000 years (Farley, 1992). Since the beginning of the 1960's, oyster mortality has multiplied throughout the world (Imaï et al., 1965; Sinderman, 1976; Mackin, 1961; Beattie et al, 1980). In the 60's and 70's, Japan and the west... |

| The role of freshwater is more difficult to comprehend. It might act as a detrital organic matter "vector" (during floods) or an anthropic waste "vector" (toxic molecules from agriculture or other industries; nutritive salts from leaching...). Its effect has been demonstrated in the Bay of Veys (Ropert and Kopp, 2000; Misko, 2003), and especially its intense but transient action, presenting high freshenings, as recorded by high-frequency multiparameter probes since 1996 [15]. On this oyster culture site, mortality could then result from osmotic shocks. The "mortality-flow" relationship, demonstrated in 2003 in the Bay of Veys (Misko 2003), has to be specified. It is found in a more sustained way in the Marennes Oléron Bay (R2 = 0.40). This result also... |

| En septembre 1984, MM. HERAL et DESLOUS-PAOLI organisèrent à La Tremblade, une "réunion méthodologie expérimentale mollusques". Cette rencontre faisait suite à un bref état qui s'était engagé au Congrès de Montpellier sur les "Bases biologiques de l'Aquaculture", où il était apparu que la terminologie et la méthodologie concernant le métabolisme des bivalves devaient être clarifiées. Grâce à une large information auprès des spécialistes français de la physiologie des bivalves, la réunion à La Tremblade a réuni un grand nombre de participants très motivés. Pendant 2 jours des discussions très animées ont permis de bien comprendre les échanges entre les bivalves et leur environnement et d'y jeter un regard neuf, ce qui impliquait une analyse critique du... |

| In the context of an increasing demand and a declining supply from fisheries, worldwide aquaculture production of abalone has greatly increased in the last decades. Selective breeding has been initiated to improve growth in major abalone species. In France, the abalone production was initiated 30 years ago and struggles to develop. This CIFRE PhD co-financed by France Haliotis, the only French hatchery in activity, was initiated to study early domestication process of farmed abalone population and to provide knowledge required to design a selective breeding program adapted to this company. Wild and farmed populations were compared, showing that, until 2013, farmed and wild abalone presented similar performances. However, lower physiological and behavioural... |

| The "trophic risk" has been demonstrated in the bioenergetic model developed in vivo and based on various diet conditions similar to those of different types of oyster culture basins (eutrophic, heterotrophic and oligotrophic) [22, 23]. The trophic resource mortality relationship differs from one basin to another, according to the quantity of this resource. Multy-varied analysis (ACP) conducted on a total of 11 oyster culture sites and handled in a database matching mortality and environmental data, show that the trophic indicator "chlorophyll a" (often coupled with temperature) is involved in a positive correlation with the mortality of both age classes (1 and 2 years old). The stock transfer from the Bay of Veys to the west coast of Cotentin in spring... |

| La mise sur le marché de coquillages marins vivants nécessite dans la majorité des cas un stockage en bassin avant expédition. Cette opération a plusieurs buts : - les débarrasser de la vase ou du sable qu'ils ont pu accumuler dans leur cavité palléale, sur les zones où ils vivaient, - favoriser l'élimination de germes éventuels (dont certains sont pathogènes pour l'homme) par le biais de l'activité de filtration des coquillages eux-mêmes, - permettre l'activité respiratoire de ces coquillages avant une période d'émersion plus ou moins longue (conditionnement, transport, mise en vente). Le coquillage conditionné et expédié est une denrée alimentaire. Avant cela (et notamment lors du stockage) il doit être considéré comme un animal d'élevage et traité en... |

| Dans le cadre des études de physiologie, la fonction de filtration intervient dans le calcul du bilan énergétique, ou permet de déterminer la quantité d'aliment consommé par les mollusques filtreurs. Cette fonction peut également être considérée dans les relations avec le poids de l'animal, la température et un certain nombre d'indices de qualité et de quantité de l'aliment dont se nourrit le bivalve. Dans un contexte de coopération internationale entre scientifiques anglais, espagnols et français, une expérimentation physiologique sur les mollusques a été réalisée en septembre 1991 à l'IFREMER La Tremblade. De nombreux objectifs motivent cette expérimentation : la comparaison inter espèces, la confrontation des techniques mises en oeuvre par les... |
