Efecto del transplant experimental de la ostra Crassostrea virginica, a un medio marino sobre la gametogenesis, supervivencia y crecimiento

Abstract

In this paper we have studied the effects of the Gulf of Cariaco (eastern Venezuela) marine environment on individuals of the American oyster (Crassostrea virginica) transplanted from natural populations present in the estuarine waters of the tributaries of the Gulf of Paria (eastern Venezuela). These Specimens were previously acclimated to full strength seawater by gradual salinity increments. The low rates of growth, survival and gametogenesis observed in the experimental groups showed that it would be extremely difficult to transplant Crassostrea virginica juveniles from their natural brackish water environment to a marine environment.
