Potentials of Kunnu Waste as Dietary Supplement for African Catfish Fingerlings

Abstract

A 72 days feeding trial was conducted on African catfish (Clarias gariepinus) fed on five diets (CP540%) in which maize was replaced with kunnu waste at 0%, 25%, 50%, 75% and 100% respectively. Fingerlings of C. gariepinus were assigned to the five diets in a completely randomized design at 36 fish per treatment in Hapa nets suspended in an outdoor concrete tank; experimental fish were fed at 5% biomass daily. Results on performance and feed utilization showed linear correlation between specific growth rate and body weight gain (p.0.05). However, feed intake increased with increased dietary levels of kunnu waste (p,0.05). The best feed conversion ratio (FCR) was obtained from the control group while the poorest was recorded at 100% replacement (p.0.05). This finding indicated that C. gariepinus can tolerate kunnu waste as dietary replacement for maize without adverse effect on performance
