Resumo: 	Since 1980, the IFREMER research laboratory "Resources Aquacoles", Sete (France), follows during the summer period, the evolution of the commercial stocks of molluscs (mussels and oysters) reared in Thau Lagoon. The data for this estimation are collected, on one hand, by surface observations and, on the other hand, by diving observations. During the years 1980 to 1984, the authors noticed an increase of oyster biomass, during the same period the mussel biomass decreased. The different simulations used to know the total filtration and the biodeposit, have shown that the impact of the increase of the total biomass is not so important as it could be feared.
