Resumen

The sustainable exploration of marine resources is a challenge to everybody worried with the quality of human life. The cultivation of marine organisms like bivalve mollusks (oysters and clams) is an alternative food source and also an option to the survival of coastal communities while the consumption of grown up in market like happens food in south and southeast regions of Brazil.
