Abstract

Eight experimental diets with four protein levels (25, 30, 35 and 40%) and two lipid levels (12 and 18%) for each protein level were formulated. The effects of the diets on the growth response of Catla catla were evaluated. The experiment was conducted in a closed indoor recirculating water system for 60 days. The best growth was obtained with diet P35L12. The highest growth was achieved with a P/E ratio of 18.51 mg protein/kJ/g. The maximum SGR (2.6%) was recorded with the same diet having 35% protein and 12% lipid.
