AbstractTwelve experimental diets were formulated to containing 35% crude protein and 429.93 Kcal gross energy 100g-1 in order to study the effects of replacement levels of dietary fish meal with soybean meal using garlic and onion on growth performance, feed utilization and whole body composition of Nile tilapia (Oreochromis niloticus) mono-sex fingerlings. Three groups of diets according to repl ...
