For lack of antibiotics, King scallop larviculture faces high mortalities. In the experimental mollusc hatchery of Argenton (Brittany, France), the presence of a vibrio, Vibrio pectinicida, associated with the stocks seems to be responsible for this low survival rate. As prophylactic methods are difficult to implement in the current structures (water sterilization, egg decontamination, isolation of the stocks), the addition of chloramphenicol is the only solution to protect the stocks. However, the use of this antibiotic, considered as dangerous for man, has been prohibited in animal production throughout the whole of Europe since 1994. The action of two other antibiotics, the erythromycine and the oxolinic acid, has been searched for in Pecten maximus... |

L'étude de la variabilité génétique chez Pecten maximus a porté sur cinq populations naturelles issues des sites suivants: la rade de Brest, la baie de Saint-Brieuc, la baie de Seine, l'ile de Skye (Ecosse) et la baie de Mulroy (Irlande). Les trois premières populations ont été échantillonnées sur leurs milieux d'origine, tandis que les populations britaniques ont été importées sous forme de naissain et semées sur deux sites différents : la rade de Brest la baie de Saint-Brieuc. L'analyse du polymorphisme enzymatique, basée sur l'étude de 13 locus (8 polymorphes et 5 monomorphes), monte que la plupart des populations étudiées sont génétiquement proches les unes des autres, à l'exception de la population d'Irlande. Cette dernière se différencie de façon... |

This report compiles 17 short and illustrated syntheses concerning the natural strategies of reproduction and the artificial control of the reproductive process for the flat oyster, Ostrea edulis, the japanese oyster, Crassostrea gigas, the mussels, Mytilus edulis and My ti/us galloprovincialis, the scallop, Pecten maximus. An additional syntheses is presented, as a comparison within molluscs, which are the main research topics at IFREMER concerning the artificial control of the reproductive processes in Marine Fish. Three main subjects are documented : 1. the ecophysiology of the natural period of reproduction in the wild, 2. the methods developed in the hatcheries for the artificial control of the reproductive periods, the gametes collection and the... |
