The study was carried out with three treatments (10, 20, 30 individual/l) in order to identify the most suitable stocking density for tiger grouper larvae (Epinephelus fuscoguttatus). The fish reared at the densities of 10 and 20 individual/l gave specific growth rate (0.0684 and 0.0678 percent/day), significantly higher than rearing at the density of 30 individual/l (0.06 percent/day
P 0.05). Similarly, the fish larvae reared at the densities of 10 and 20 individual/l reached the final total length (38.40 and 37.45mm) considerably higher when reared at the density of 30 individual/l (27.50 mm
P 0.05). The fish larvae reared at the densities of 10, 20 individual/l obtained the survival rate (5.31 and 5.25 percent) substantially higher in comparison to the density of 30 individual/l (3.27 percent
P 0.05). Results showed that the most appropriate density for rearing the tiger grouper from fry to fingerling stage is 20 individual/l in order to optimize the growth, survival rate and economic efficiency.
