ABSTRACT
This study examined the total replacement of fishmeal (FM) with poultry hatchery waste meal (PHWM) in practical diets for African catfish (Clarias gariepinus). Five iso-nitrogenous diets containing levels Diet1, 0% (control); Diet 2, 25%; Diet 3, 50%; Diet 4, 75% and Diet 5, 100% of PHWM as a replacement for FM were fed to three replicate groups of African catfish with an initial weight of 5.1±0.01 grams. Diet 5 (100% PHWM) has the best growth performance and feed utilization because it has the highest values in weight gain (1.03) with significant difference (P< 0.05) as well as feed intake (1.49) with significant difference (P< 0.05) and has the best feed conversion ratio (FCR), (1.48) with significant difference (P< 0.05). Relative weight gain (RWG), (12.64) and specific growth rate (SGR), (1.67) were highest in Diet 5 but were not significantly different (P >0.05).
