The effect of stocking density on the survival and growth of silver rasbora (Rasbora argyrotaenia) Larvae

The purpose of this study was to assess the effect of different stocking densities on the survival and growth of silver rasbora (Rasbora argyrotaenia) larvae as new aquaculture species. A total 3,000 larvae aged 2 days after hatching (mean body weight = 1.08 ± 0.06 mg; mean total length = 3.14 ± 0.17 mm) were assigned into five stocking density treatments (A – 10, B – 20, C – 30, D – 40, E – 50 individuals L⁻¹; four replicates per treatment) and reared for 21 days. The stocking density affected both survival and growth of silver rasbora larvae (P < 0.05). The highest survival rate and individual growth occurred at 10 fish L⁻¹ treatment. Based on the highest biomass gain, the optimum stocking density treatment was 20 fish L⁻¹. We suggest using 20 fish L⁻¹ stocking density in silver rasbora larviculture because estimated more efficient and profitable economically.
