Resumo: | In the Marennes-Oléron oyster culture basin, the cultivated oyster stock shows an unbalanced age distribution: 25 000 to 30 000 tonnes are commercialized each year for a total cultivated biomass of 95 000 tonnes (1993). The biological overexploitation of the basin requires a reduction of the stock in order to get back to productivity rates that are compatible with the restrictions of the oyster market. This study gives an estimated natural deposit biomass of around 3 000 tonnes. An estimate of the abandoned and wild oyster biomass shows that 20 000 tonnes of these animals can be considered as competitors to cultivated oysters. [...].
