Effect of Stocking Density on Growth, Survival Rate, and Damage of Caudal Fin in Larval to Young Puffer Fish, Takifugu rubripes

Abstract

In order to clarify the optimum stocking density for seed production of the puffer fush, Takifugu rubripes, five series of rearing experiments from larva to young were carried out under different density conditions. The estimation of the optimum stocking density was based on growth, survival rate, and degree of loss of the caudal fin by cannibalism. The results obtained showed that the optimum stocking densities of larva (3.3-10.0 mm TL), early juvenile (10-40 mm TL), late juvenile (30-50mm TL) and young (50-75mm TL) were approximately 25000, 2800, 600 and 100 individ./m³, respectively.
