| Historically, the research on mollusc reproduction conducted by the Ifremer aimed at improving mass production in order to support new activities (Japanese clam for example) or to compensate for insufficient natural reproductions (abalone, king scallop). Nowadays, priority has been given to the preservation of natural resources and the optimisation of shellfish culture in order to support activities that are strongly represented by a profession, especially oyster culture. The studies that have been carried out in the field of oyster genetics for about ten years highlighted the limits of our knowledge on reproduction control as well as the high sensitivity of mollusc farms to the multiple assaults of their outside environment. As far as professional... |

| 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... |
