Growth response, Feed utilization and Nutrient retention in monosex tilapia (Oreochromis niloticus) fed with floating and sinking pellets in a recirculating aquaponic system

Abstract

An experiment was conducted for 10 weeks to compare the effects of feeding sinking and floating commercial pellets in monosex tilapia (Oreochromis niloticus) reared in a recirculating aquaponic system. Each of the commercially available isonitrogenous floating and sinking pellets were tested in triplicates. The water quality parameters during the experimental period were within the suitable range for fish culture. At the end of the rearing period, significant difference (P0.05) was observed in the chemical composition of O. niloticus except lipid content. In terms of growth.
