Resumo: 	In the scope of the "Coastal ecology" thematics, the LCPC supervises a study which aims at understanding the causes and mechanisms of the summer mortality of C. Gigas. Different types of analysis conducted on the oyster (quality index, immunology, cell biology, etc.) enable the identification of a one month period preceding the acute mortality episode and during which the animals undergo a stress situation and become weaker. The energy balance (material balance) is close to zero for the most exposed stocks. Studies conducted on the environment included the search for pathogens and contaminants in the water column, the sediment and the animal, as well as the analysis of the hydrological features of the mass of water. The weakening period corresponds to an important change in their diet. This diet shifts from a terrigene and pelagic dominance to a phytobentic predominance. A double stress mortality model is suggested.
