| At the end of the 1980s, after two decades of aquaculture research in molluscs, Ifremer initiated its first genetic studies. These new studies quickly revealed the limits of knowledge in aquaculture, particularly in terms of controlling oyster reproduction. This presentation attempts to summarize the available information on genetics in aquaculture. In particular, breeding practices in the 1980s involved populations of broodstock, while genetics requires modern techniques where individuals, not just populations, can be identified. Controlling reproduction at the individual level in oysters raises new questions that existing protocols cannot address, especially in terms of controlling sex determination, individual maturity, spawning synchrony, chemical... |

| 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... |
