The study evaluates the growth performance and survival of hybrid African catfish larvae (Clarias gariepinus X. Heterobranchus bidorsalis) fed different diets: live Artemia nauplii, decapsulated Artemia cysts, live Ceriodaphnia sp and commercial dry diet (50% crude protein). Catfish larvae of mean weight 10.01±0.01mg of mean length 9.05±0.09mm were fed from the onset of exogenous feeding for 28days in plastic aquaria tanks (10L capacity each). At the end of the feeding trial, the highest weight gain, 889.99±5.00mg was recorded for the larvae fed with decapsulated Artemia cysts followed by those fed with live Ceriodaphnia with mean weight gain of 442.66 ± 2.24mg. The least weight gain 60.42 ± 1.80mg was obtained in larvae fed with commercial diet. The best and the least specific growth rates (SGR), 16.07 ± 0.02 and 6.97 ± 0.01 were also obtained in larvae fed decapsulated Artemia cysts and commercial diet respectively. Statistically, all the results of the growth parameters obtained from the different diets were significantly different (p |
