Farming of filter feeding bivalve molluscs such as oysters is frequently cited as a sustainable activity. However, there is no quantitative assessment to support this fact. The aim of this work is to evaluate the environmental sustainability of a mangrove oyster (Crassostrea spp.) production system, with seeds collected in the wild, in Cananeia-SP, Brazil using sets of indicators. The indicators were calculated to reflect the use of natural resources, the efficiency in the use of these resources, the release of pollutants and the conservation of genetic diversity and biodiversity. The culture use low space and water, does not depend on the addition of nitrogen and phosphorous and shows potential to remove surplus nutrients in the aquatic environment and absorb greenhouse gases. In this way, we concluded that the oyster production system of Cananeia showed high environmental sustainability
