Rock oyster Striostrea prismatica (Gray, 1825): biology, exploitation and conservation

ABSTRACT Oyster or rock oyster (Striostrea prismática) is a bivalve mollusk highly appreciated among traditional seafood in several Latin American countries. Uncontrolled capture and lack of techniques for its culture, threaten their growth and conservation, as a decrease in its population has been...
