Abstract

An experiment about the effect of three stocking densities (10, 30 and 50 larvae L -1 ) on growth and survival of the selais fish larvae, an important commercial species, and the source of income for the rural community was conducted at the Fish Hatchery of the Agriculture Faculty, Universitas Islam Riau, Indonesia. Three-day post- hatched larvae (0.0012±0.00 g in weight ; and 0.03±0.00 cm in length) were used as test fish that obtained from the artificial spawning of the selais fish broods. The fish larvae reared in recirculation system with a water flow rate of 0.05 L -1 , and fed with silkworms (Tubifex sp).This study used a completely randomized, non-factor design with three treatments and three replications. The best growth in weight and growth in length (of 0.87±0.00 grams and 5.39±0.49 cm, respectively) were found in the T1 (stocking density was 10 larvae L -1 ). The highest survival rate (57.33±7.72) was attained in T1 (stocking density was 10 larvae L -1 ) while the lowest survival (51.60%) attained in T3 (stocking density was 50 larvae L -1 ) . Growth rate and survival rate of the selais fish larvae were inversely proportional to the density of the fish larvae.There’s no significant effect of stocking density on the growth and survival of the selais fish larva (P>0.05).
