Abstract
A seventy five days feeding experiment was conducted on juveniles of Oreochromis mossambicus having the initial weight of 0.9267±0.1464 g. The ingredients were fish meal @200g/kg, rice protein @530g/kg, boiled rice @100 g/kg, squid @ 20g/kg, shrimp @ 100g/kg, fish oil @ 4 ml/kg, salt @ 025g/kg, minerals @ 0.05g/kg and vitamins @ 10g/kg mixed and fed to juveniles twice a day at 5% of average body weight. The weight gain % and differences between initial and final weights were increased with respect to 0.2833±0.1080 and 21.90 ±11.68 (P > 0.05). Food conversion ratio (FCR), protein efficiency ratio (PER) and specific growth rate (SGR) were significantly different from the specimens reared in extensive cultural system.
