Growth response of Nile tilapia (Oreochromis niloticus) fed graded levels of sun-dried cassava peel meal
A study was conducted at the farm section of the department of fisheries technology, Federal polytechnic Nekede, Owerri in Factorial design of five treatments of cassava peel meal at 0%, 25%, 50%, 75%, and 100% graded levels were formulated. The casssava peel meal was sun-dried for 48 hours, ground, and added to the feed fed to 150 fingerlings of Oreochromis niloticus into 10 tanks in triplicates, and fed twice daily at 5% body weight for 60 days. The result shows that fish fed with 100% cassava peel meal had the highest mean weight gain of 10.46 ~c 0.0l and specific growth rate of 1.23 ~c 0.04. The second best result was shown in fish fed with cassava peel meal with weight gain of 9.93 ~c 0.03 feed conversion ratio (FCR) of 1.75 ~c 0.04 and specific growth rate of 1.24 ~c 0.02. The poorest result was shown by fish fed 25% cassava peel meal with the lowest survival rate, weight gain,feed intake and specific growth rate respectively. This connotes that diet with 100% fed graded level of sun-dried cassava peel meal can best be utilised at a ratio of 75% to 15% CPM, and second best diet with 75% fed graded level of sund-ried cassava peel meal could also be utilized at 11.25% reduction due to its survival rate parameter over the best. Moreover, this proportion should be utilised for improved growth of Nile tilapia (Oreochromis niloticus) for profit maximization.
