A 56-day feeding trial to investigate the effects of feeding varying levels of substituted Soybeam meal (SBL) with Pigeon pea seed meal (PSM) on the performance and carcass characteristics of Clarias gariepinus was conducted. Five isonitrogenous 40% crude protein diets were formulated where PSM Clarias gariepinus (15.74 ~c 1.22g) stocked at 15 fish/50 litres tanks were fed diets in triplicates twice daily to satiation and weight changes recorded weekly. Fish fed diet with 25% and 100% PSM inclusion gave the highest mean weight gain of 25.47g and 23.34g respectively (P>0.05). There were no significant difference (P>0.05) among the weight gain of other treatments. Fish fed diet containing 0% SBM and 100% PSM gave the highest gross food conversion efficiency and percentage weight gain of 43.50g and 12.l8g while fish fed diet containing 50% SBM and 50% PSM had the lowest of 35.67 and 9.99 respectively with no significant changes compared with other treatments. For good growth, fish farmers are advised to consider Pigeon pea seed meal either as a partial (25%) or total replacement (100%) for soybean meal in the diet of Clarias gariepinus juveniles.
