Each treatment was in triplicates. The fingerlings were fed with formulated standard diet of 30% crude protein at 5% body weight. Fish were fed twice daily for 185 days. The total yield of fish was significantly greater (P<0.05) in earthen pond, 1.93kg than those in sandcrete 1.47kg and plastic tanks 1.42kg. There was significant difference (P<0.05) in final weight gain, feed conversion ratio, mean daily weight gain between O. niloticus fingerlings stocked in the three culture enclosures. Fish in earthen pond had the highest weight gain (135.9g) and specific growth rate (1.54%). There was significant difference (P<0.05) in the Net profit obtained and benefit cost ration for the three culture enclosures. The study considered earthen pond to be more productive and the most ideal culture enclosure for growth optimization of O. niloticus Keywords : Growth performance, Economic performance, Culture Enclosures, Oreochromis niloticus
