Mono-sex population of Oreochromis niloticus fingerlings were collected from Nigerian Institute for oceanography and Marine Research Sapele station Hatchery and acclimatized for a week and randomly stocked at density of 300 fish/tank in nine fibre glass tank. The fingerling were fed daily 800h and 1600h with three different types of feed (Dry chicken manure, mixture of chicken manure and commercial diet, and commercial (coppens) only. Each treatment was replicated three times. The water quality parameters are within tolerant limit. The growth response in all the treatment wee generally satisfactory. Though treatment T3 Tanks fed with commercial diet only (coppens) had better growth performance compared with treatment T2 and T1, chicken manure and mixture of chicken manure and commercial diet respectively. The results demonstrate the feasibility of rearing all male tilapia (O. niloticus) fingerlings in fiber glass tanks.
