| In order to improve oyster culture, many research programs try and propose new methods aiming at improving genetically the product performances and quality (selection, polyploidisation). As for terrestrial animal production, the continuity of the different works as well as the spreading of the genetical progress would be made easier by the development of conservation techniques of the selected genotypes. Cryopreservation, which is often used in selection programs of terrestrial animals or fish farming species, is not always available for bivalves. This technique would enable the conservation of the gametes of individuals selected for their high growth potential, their resistance to diseases and/or their quality for a smaller cost and less risks than the... |

| Summer mortality has been reported in the Pacific oyster, Crassostrea gigas, for many years in Japan, US and Europe. It affects both adults and juveniles and the causes of this phenomenon are complex. Environmental, physiological or pathological putative causes were studied all over the world. Recently, the MOREST project ((MORtalitEStivale) a multidisciplinary project (2001-2005) focused on his problem led to a better understanding of this phenomenon in France. The results showed in these geographical conditions, the main interactions between the oysters, their environment and certain pathogens. |
