Resumo: | After a short bibliographical study of the different approaches for determination of the trophic capacity of a bay for molluscs culture, the authors, with a global mode, show the relations between the growth performance of the oysters Crassostrea gigas in relation with the cultivated stocks. The volumes of consumed and assimilated food are calculated for the stocks in relation with the incoming volumes of water in the bay and the residence time for neap tide and spring tide. The authors find a decrease of growth rate in relation with the volume of consumed food. When it is above 60% and when the volume of assimilated food is above 20%, there is a large decrease of the growth of oysters.
