Producción secundaria de una población de Chione cancellata (Bivalvia: Veneridae) de la costa sur del Golfo de Cariaco, Venezuela

Production and biomass of Chione cancellata, an abundant species in Thalassia testudinum sea beds, were studied from March, 1984 to May, 1985 in Guaracayal, Cariaco Gulf, Venezuela. The population distribution ranges were stable. Many individuals were 20-30 mm long (80%) and recruitment was low. The...
