The effect of floating and sinking diets on the growth performance, nutrient conversion efficiency, and yield of C. gariepinus at various life stages has been investigated. The need to identify and recommend the right type of feed and nutrient composition to be fed to catfish under culture conditions became necessary since fish feed accounts for over 60% of the total cost of production. Investigators have studied the effect of floating and sinking diets on the growth performance and survival rate of C. gariepinus, however studying them at the various life cycle, feed conversion efficiency, and also the yield it produces has not been extensively investigated, thus the need for this research. The benefit of this research outcome will help the fish farmers to know the right type of feed and nutrients required to improve performance a various life stages of the fishes.
