Resumo: | 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 fertilization,  3. the descriptive knowledge of the gonads (anatomy, cellular organisation) and of the gametes (physiology, biochemistry, cellular biology).  For the scallop, Pecten maximus, more is known on ail the subjects since this species has been studied for 20 years as a model for hatchery improvements and reseeding experiments. The results concerning the mussels are exclusively confined to the natural description of the reproductive spawning periods and consequences. The results affecting oysters are wild documented on the strategies observed in the wild. Less, but increasing information is available on the artificial control of the spawning season, on the gonads and on the gametes. The 18 syntheses have been orally presented at IFREMER/NANTES (FRANCE). 14-15th of november.
