Resumo: | A study on mortalities, growth and fattening of the oyster Crassostrea gigas was carried out spring with the autumn 1987 in four sites of bay of Bourgneuf. Mortalities, more important in spring, prove to be higher in the sectors North compared to the Southern sectors of bay of Bourgneuf.  The performances of growth are rather weak when they are compared with other French oyster sectors. They however present a better production in the cattle-breeding areas located at the South of bay. The spring phase is marked by the formation of glucidic reserves, at the moment of the reheating of water, which is quickly transformed, in the majority of the sites, in lipids of reserves of the ovocytes, during the gamétogenèse.   The state of fattening of Crassostrea gigas high in 1987 out of bay of Bourgneuf is poor on the whole of the studied sectors and throughout the year. The physiological index of condition reveals a satisfactory state only during the phase of maturation of the gonades (IC/80).
