| Abstract | The present study was conducted to determine the possibility of replacing the commercial fish meal (FM) with thelocally produced fish by-product meal (FBPM) in the diets for red tilapia (phenotypically Oreochromis niloticus) fry (bodyweight ~0.54 g). Five isoproteic and isolipidic experimental diets with 0, 25, 50, 75, and 100% inclusion levels of FBPM wereformulated and hand-fed to triplicate groups of fish (20 fish/ group) twice a day. After 6 weeks, fish fed FBPM 50 attained thehighest final body weight (4.7?0.3 g; mean ?SD), weight gain (764.8?47.2%), specific growth rate (5.1?0.1%/day), feed intake(7.2?0.4 g/fish), protein efficient ratio (1.7?0.2), and the best feed conversion ratio (0.9?0.1). All fish fed FBPM-based dietsalso attained the better survival (93-95%) than those fed control diet (83%). Since FBPM is a by-product of marine fisheriesindustry, it should be considered as a major protein source in the diets for red tilapia fry |
