Biological control of incrusting organisms and sediments in Chilean oyster cultures

Abstract The oyster culture has the incrusting organism as problem for production, in this context, it evaluated biological control against and sediments introduction of gastropod Tegula atra (Lesson, 1830) Chilean oysters (Triostrea chilensis Phillippi, 1844) cultures conditions starvation presence absence located floating cages bottom cultures. predation mechanic effect on T. grazing generated a decreasing seven days 19.8% 13.7% organisms cage by effects gastropods without respectively. Whereas had decrease 12.6% 11.4% with removed were mainly algae, colonial ascidia, polychaeta, bryozoan small crustaceans.
