Abstract: The nutritional suitability and cost effectiveness of groundnut cake (GNC) and groundnut husk (GNH) as protein sources in the diet of Nile tilapia (Oreochromis niloticus), mean initial weight 4.24 ± 0.20 g, was evaluated over a 56-day growth period. Five isonitrogenous (320 gkg−1), isolipidic (100 gkg−1), and isoenergetic (18 KJg−1) test diets were formulated in which GNC proteins replaced fish meal (FM) protein at levels of 25% and 50%, and GNH protein at 10% and 20%. The control diet had FM as the sole protein source. The growth experiment was conducted in plastic tanks in a recirculation system; each dietary treatment was in triplicate. After feeding fish at 4%–6% body weight per day, GNC and GNH protein replacements up to 50% and 20%, respectively, did not significantly (P < 0.05) affect growth and feed utilization. The study indicated that GNC and GNH protein could replace at least 50% and 20% of fish meal protein, respectively, in the diet of O. niloticus fingerlings without adversely affecting growth, feed efficiency, whole body composition, and nutrient digestibility. Generally the GN by-products-based diets were more cost-effective than the fish meal-based diet, particularly GNH replacing 20% fish meal protein.
