Abstract: Induced breeding and seed rearing of an endangered bagrid catfish, Horabagrus brachysoma were conducted. The female brood responded to stripping either in single or double dose of ovaprim at 0.8-1.5 ml/kg body weight at 13-20 h latency period. The stripped egg weight varied between 14-20 g and the fecundity of the catfish ranged 1.6-1.8 lakhs/kg body weight indicating it as a high fecund catfish. The fertilization and hatching of the eggs were observed to be 50-81 and 27-68% respectively during different trials. The hatchlings were 1.28 mg in weight and 5 mm in length. The larvae accepted well to live plankton and performed well, resulting in a survival rate of 64-76%. The fry also performed well at two density levels (50 and 100/m2) resulting over 90% survival during fingerling production.
