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.
