This study evaluated the effects of stocking density on growth, feed utilization and body composition of juvenile starry flounder (Platichthys stellatus). Starry flounder juvenile were reared at five stocking densities [ratio of body surface area to tank bottom area: 3, 2, 1, 1/2 and 1/3]. At the end of 80 days feeding trial, survival of juvenile starry flounder reared at various density conditions was ≥ 89% and there was no significant difference among all experimental groups. Weight gain of fish at the 3 group was significantly lower than that of fish at the 1 group. Specific growth rate of fish at the 3 groups was significantly lower than that of fish at the 1/3, 1/2 and 1 groups, but not significantly differ from that of fish at the 2 group. Feed consumption of fish at the 1/3 group was significantly lower than that of fish at the 2 and 3 groups, whereas the 1/2 and 1 groups were not showed significantly different. Feed efficiency of fish at the 1 group was significantly higher than that of fish at the 2 and 3 groups, but not significantly differ from that of fish at the 1/3 and 1/2 groups. Hepatosomatic index of fish at the 1/3 group was significantly higher than that of fish at the 2 and 3 groups, whereas the 1/2 and 1 groups were not showed significantly different. Based on these results, the optimum stocking density for juvenile starry flounder (6.7 g/fish) is a ratio of body surface area to bottom area tank of 1.
