Production of Mugil cephalus fed different diets was compared. Fingerlings of M.cephalus with an initial weight (23.75±1.14) were distributed in four earthen ponds with a stocking density of 14000/h-1. The ponds were prepared and fertilized by 1200 kg /h-1 chicken manure, 150 kg/h-1 super phosphate and 60 kg/h-1urea. Four diets different in their total crude protein contents and diet type were formulated. Diet 1, contain 25% crude protein and was in pelleted form. However, diet 2, 3 and 4 in powder form with 25,20 and 15.64 % crude protein, respectively. The diets were offered at 3% rate of body weight (B.W), in two times a day. Growth performance showed significance differences (p< 0.05) between diets. The pelleted diet 1 gave the highest performance, followed by diets 2, 3 and 4, respectively. Highest total fish yield was recorded with diet 1, (3834 kg/h-1), followed by diet 2 (3427 kg/h-1), diet 3, 2848 and finally diet 4 (2484 kg/h-1). The results suggest that the utilization of pelleted diet with 25% crude protein can enhance the performance and net yield production of M. cephalus.
