| Among the marine molluscs, Pacifie oyster, Crassostrea gigas, is actually the most reared specie in the world. Noticely in France, where it was imported between 1960 and 1970, and replaced by Portuguese oyster, Crassostrea angulata, which specie was decimated during this period because of iridoviruses. Uncontroled introductions of new species may however be hazardous. Indeed, they might be responsible for the appearance and the dissemination of new diseases of bivalve molluscs in importing country. In addition to these observations, the quasi monobreeding of Pacific oyster in France enhances the necessity to develop research concerning the diagnosis of pathologies affecting this specie, namely the diagnosis of viral diseases. Several families of viruses... |

| Progeny of Crassostrea virginica oysters, introduced into France in 1992, were reared during 1992 and 1993, to test their growth performances. These assays were performed to investigate the possible replacement of Crassostrea gigas with a non indigenous species, Crassostrea virginica. During the summer of 1993, sporadic mass mortalities (80-90%) occurred among young, Crassastrea virginica, oysters reared in the IFREMER nursery in La Tremblade (Charente Maritime). |

| Le but de ce programme pathologie est de recherher et d'étudier les agents pathogènes connus et inconnus chez les mollusques bivalves marins, plus particulièrement chez l'huître creuse, Crassastrea gigas, afin d'identifier d'éventuels agents causant des mortalité, de proposer des mesures prophylactiques et de définir des conditions zootechniques permettant aux professionnels de limiter l'impact des maladies sur leur cheptel. La présence de maladies, chez les mollusques bivalves marins dont l'impact socioéconomique peut être catastrophique pour les productions conchylicoles, et l'accroissement des échanges de produits d'aquaculture entre les pays de la CEE et avec les pays tiers nécessitent le renforcement des recherches dans les domaines de la pathologie.... |
