Growth and survival of hybrid catfish fingerlings under three dietary treatments in concrete tanks

Abstract

Fingerlings of African catfish (Clarias gariepinus x Heterobranchus longfilis) were reared in concrete tanks under three dietary treatments for 60 days. Tadpole meal produced the highest fingerling survival rate (90%), with a mean weight value of 2.68g at harvest. The best growth results were obtained among the fish that were fed on fresh tilapia meal, but this treatment also had the lowest fish survival rate (52%). An equal mixture of tadpole and tilapia meal gave fish mean weight value of 2.65g and a survival rate of 80%.
