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
<0.05) mean length (1.40±0.0214cm) and SGR (0.083%) were observed in treatment B followed by treatment A (1.10±0.0204cm, 0.069%). The least SGR (0.064%) was observed in fry solely fed on the compound diet (0.994±0.0205cm). The results of the study demonstrate a comparatively higher growth and fry survival (82.2%) when fed on the mixture of live rotifers and formulated feed, seven days after hatching.
Since no artificial feed formulation is yet available to completely substitute feeding live prey to young fish, it is concluded that a mixture of live and formulated diets are more suitable for feeding the African catfish fry seven days post hatch.
