Abstract

The induce breeding of endangered Indian butter catfish, Ompok bimaculatus in captivity was attempted. Prepatory dose of Ovaprim hormone @ 0.5 ml was administered for gonadal development prior to breeding experiments for two months consecutively. In breeding the inducing agent ovaprim was given intramuscularly @ 1.5 ml/kg body weight. In about eight hours successful natural breeding occurred. Fertilization was 90%. In 24 hrs hatching was completed. About 5000 spawn was procured on 4th day. Survival from egg to spawn was 80%.
