N2 - Silver rasbora (Rasbora argyrotaenia) is a high-value commodity. The problem in cultivation of silver rasbora is long goanadal maturation period. The gonadal maturation period can be accelerated by manipulation of feed using omega-3. Omega-3 can affect reproductive performance, egg development, and fish embryogenesis. The purpose of this study was to determine effect of addition of omega-3 in feed on gonadal maturity level and fecundity of silver rasbora. The observed parameters are gonadal maturity level, gonado somatic index, gonado index and fecundity. This research applied a completely randomized design (CRD) method which consist of four treatments, namely control (0 mg/kg feed), P1 (2500 mg/kg feed), P2 (5000 mg/kg feed), and P3 (7500 mg/kg feed). The result of this study was indicate addition of omega-3 to feed increased gonadal maturity at GML IV stage and had a signicantly effect on the gonado somatic index, gonado index, and fecundity of female silver rasbora. The optimal dose of omega-3 for silver rasbora gonads is 7500 mg/kg of feed, which results in an increase in gonadal maturity to GML IV with a GSI of 18,89 ± 2,24%, a GI of 143,63 ± 6,66 and fecundity of 924,76 ± 9,21 eggs/parent.
