Comparative Study on Growth and Economic Performances ofNile Tilapia, Oreochromis niloticus Reared Under DifferentCulture Enclosures in Akure, Nigeria

Abstract

This study was conducted to determine the growth and economic performances of Nile Tilapia Oreochromis niloticus reared in different culture enclosures in Akure. 900 O. niloticus fingerlings (mean weight 8.30±0.06g) were acclimatized for 24 hours, out of which one hundred fingerlings were randomly selected and distributed into the three prepared culture enclosures (plastic tanks, sandcrete tanks and earthen ponds) of the same size (3.0m X 2.8m X 1.0m). 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
