| The monitoring of the reproduction of Crassostrea gigas, and more occasionally that of the mussel Mytilus edulis, is carried out in the Marennes-Oléron Basin, each year, from June through to September. This report presents the main results obtained in 1997, 1998, 1999, 2000 and compares them. It also recalls the techniques used and provides, in appendix, some bibliographic information on larval development. |

| Les conditions météorologiques semblaient cette année à priori favorables à la reproduction des moules. Cependant, le maturation des gonades a été très lente. Ainsi, les premières pontes, de faible importance, ont eu lieu début Avril. Plusieurs émissions tardives sont apparues fin Mai et se sont poursuivies jusqu'au début du mois de Juillet. Elles n'ont pas été importantes et ont conduit à une faible quantité de larves au stade fixation. Un captage "moyen" a été observé début Mai. Ensuite, la présence de quelques larves grosses n'a pas permis un recrutement suffisant. Généralement, suite à la période de reproduction les moules reconstituent rapidement leur réserve; or cette année, elles sont restées maigres jusqu'à la fin Juillet. Le fort déficit... |

| Abnormal mortality outbreaks occurred in the majority of Pacific oyster (Crassostrea gigas) producing areas in France in 2008 during the summer period. These outbreaks were usually sudden and severe (up to 100%) and affected essentially spat (oysters less than 1 year-old) and juveniles (12 to 18 month-old oysters). Crassostrea gigas was the single affected species Mortality outbreaks were first observed from mid May to mid June in Brittany, Vendée, Charente Maritime and Mediterranean coast A second episode of massive mortality events was reported at the end of June and the beginning of July. All oyster production sites were affected except some particular locations including Arcachon Bay and Brittany. Mortality occurred latter in Arcachon Bay in August.... |

| Virus-induced genes were identified using suppression subtractive hybridisation (SSH) from Pacific cupped oyster, Crassostrea gigas, haemocytes challenged by OsHV-1. A total of 304 clones from SSH forward library were sequenced. Among these sequences, some homologues corresponded to (i) immune related genes (macrophage express protein, IK cytokine, interferon-induced protein 44 or multicopper oxidase), (ii) apoptosis related genes (Bcl-2) and (iii) cell signalling and virus receptor genes (glypican). Molecular characterization and phylogenic analysis of 3 immune-related genes (macrophage expressed protein, multicopper oxidase and immunoglobulin domain cell adhesion molecule) were performed. Finally, quantitative PCR revealed significant changes in the... |

| Suite aux surmortalités observées au sein des élevages de moules touchant à la fois les animaux adultes et les juvéniles au mois de mars, dans les Pertuis Charentais, la Direction Générale de l’Alimentation (DGAl) a adressé une saisine à Ifremer le 04 avril 2014. Celle-ci fait état d’une demande d’appui scientifique et technique d’Ifremer pour tenter d’apporter des éléments de réponse par rapport à cette mortalité subite et importante. L’Ifremer a proposé un projet d’action permettant l’expertise du phénomène de surmortalité de la moule bleue, selon 3 axes : l’impact environnemental, la pathologie et les caractéristiques physiologiques des moules. Il s’agit de mettre en évidence la présence ou non d’agents infectieux connus ou émergents, d’apporter des... |

| Proximate biochemical analysis (proteins, lipids and carbohydrates) are performed on a regular basis by the various laboratories fom the Aquaculture Resources Directorate. Methods initially developed to analyse hydrological parameters were firstly transfered to assess meat components.1t appears now important to review and update the commonly used methods (Lowry et al., (1951), Dubois et al.,(l956), Marsh et Weinstein, (1966)), for our specifie purposes. A round table was organized to facilitate discussion among researchers and technicians from both Directorates 'Aquaculture Resources' and 'Product Valorization'and external partners, University of Caen. Several communications reviewing former and recent studies were done. Colleagues from the Directorate... |

| Massive mortality outbreaks have been reported in France since 2008 among Pacific oysters, Crassostrea gigas, with the detection of a particular OsHV-1 variant called μVar. Virus infection can be induced in healthy spat in experimental conditions allowing to better understand the disease process, including viral gene expression. Although gene expression of other herpesviruses has been widely studied, we provide the first study following viral gene expression of OsHV-1 over time. In this context, an in vivo transcriptomic study targeting 39 OsHV-1 genes was carried out during an experimental infection of Pacific oyster spat. For the first time, several OsHV-1 mRNAs were detected by real-time PCR at 0 h, 2 h, 4 h, 18 h, 26 h and 42 h post injection. Several... |

| Cette étude constitue une des trois actions engagées dans le cadre du Contrat de Plan IFREMER - Poitou-Charentes (1994-1998) sous l"intitulé Valorisation des Claires Ostréicoles. Les deux actions complémentaires concernent la compréhension et l'amélioration du verdissement des claires sous la direction du Pr. J.M. Robert de l'Université de Nantes/lSOMER et la production de masse de microalgues afin de stimuler la croissance de mollusques filtreurs sous la direction de Dr. J. Hussenot du CREMA L'Houmeau. Ce programme répond directement à la demande des professionnels afin d'optimiser les conditions d'élevage de l'huître creuse C. gigas en période d'affinage qui à l'heure actuelle, ne permettent pas le contrôle de la qualité finale du produit. L'objectif... |

| Polyphasic analysis of five new Vibrio isolates originating from the haernolymph of diseased cultured oysters is described. The new isolates were closely related to Vibrio splendidus, having 98 % 16S rRNA gene sequence similarity. gyrB phylogenetic analysis, fluorescent amplified-fragment length polymorphism (FAFLP) fingerprinting and DNA-DNA hybridization experiments clearly showed that the new isolates form a tight genomic group that is different from the currently known Vibrio species. It is proposed to accommodate these isolates in a novel species, Vibrio crassostreae sp. nov. (type strain LGP 7(T) =LMG 22240(T)=Clp 108327(T)). Phenotypic and chemotaxonomic features that differentiate V. crassostreae from other known Vibrio species include arginine... |

The new isolates were closely related to Vibrio splendidus, having 98 % 16S rRNA gene sequence similarity. Phylogenetic analysis based on DNA gyrase subunit B (gyrB), RNA polymerase Quo factor (rpoD), replication origin-binding protein (rctB) and transmembrane regulatory protein (toxR) genes, fluorescent amplified fragment length polymorphism and DNA-DNA hybridization experiments clearly showed that the new isolates form a tight genomic group that is different from the currently known Vibrio species. It is proposed that these new isolates should be accommodated in a novel species, Vibrio gigantis sp. nov. Phenotypic features that... |
