Despite the local availability of protein rich peanut-based ingredients, fish meal has persisted as the conventional source of dietary protein for aqua feeds in Uganda. A 20-week field experiment was conducted in to determine the Relative Growth Rates of Nile tilapia fishfed on fish meal and peanut-based diets in earthen ponds at Busoga University farmland in Iganga district of Eastern Uganda. Six-week old juvenile fish of mean weight of 22.0 grams were stocked and fed at 5% of their body weight (BW) daily. Three test diets were utilized namely the fishmeal (FM)-based diet and the peanut based diets which included; peanut meal (PNM)-based diet & mixed plant meal (MPM)-based diet. The existing locally available commercial feed (CF) for Nile tilapia acted as the control diet. Although the mean Relative Growth Rate (RGR) of fish fed on the FM-based diet was the best, it was not significantly different (p>0.05) from that fed on the MPM-based diet. A significant difference (p<0.05) in mean RGR’s existed between the FM and PNM-based diets and between MPM and PNM-based diets. Basing on the RGR’s of the experimental fish, the MPM-based diet should completely substitute fish meal in the diet of Nile tilapia.Pages: 306-312 | 764 Views 11 DownloadsDownload Full Article:
