Performance of African Catfish Clarias gariepinus (Clarridae) fry fed on live rotifers (Brachionus calyciflorus), formulated diet and a mixture of rotifers and formulated diet

Long larval and fry rearing period due to unreliable live food sources are problematic in fry rearing process affecting aquaculture production in most hatcheries. As a result, this study investigated the performance of African catfish (Clarias gariepinus) fry fed on live rotifers, a mixture of rotifers and formulated diet (Ugachick feed 45%). Seven days post hatch fry of Clarias gariepinus were reared under three different treatments; A, B and C with triplicates in a complete randomized design in 40L concrete tanks. Fry in treatments A and C were exclusively fed on live rotifers and formulated feed respectively. In B, the fry were fed on mixture of live rotifers and formulated feed for 15days. At the end of the experiment, final mean total length (TL), specific growth rates (SGR) and survival rates (SR) were determined. Significantly highest (P
