A feeding trial was conducted to assess the replacement value of Ipomoea aquatica based diet as dietary replacement of maize in the diets of juvenile Clarias gariepinus. Five isonitrogenous diets were formulated to contain 0 (control diet), 15, 30, 45 and 60% Ipomoea aquatica. Each treatment was carried out in triplicate using ten C. gariepinus juvenile per replicate with mean initial weight of 9.0 g. The fish were fed at 5% body weight per day for a period of 8 weeks. The best growth response in terms of mean weight gain was obtained in fish fed 15% I. aquatica diet inclusion (35.57±3.44 g) while fish fed 60% I. aquatica diet had the lowest growth response (23.80±1.18 g), the highest FCR was obtained in fish fed 60% I. aquatica (1.79±0.04) while the lowest was obtained in fish fed 15% I. aquatica (1.58±0.06). There was no significant difference (p>0.05) in all the parameters of the treatments. The results revealed that any of the inclusion level can be used up to 60% inclusion level of I. aquatica. However, 15% inclusion level gave the best result in terms of growth. © 2014 Academic Journals Inc.
