Abstract
A feed trial was conducted to determine growth of three Indian major carps i.e. Catla calla (0.31g), Labeo rohita (0.22g) and Cyprinus carpi° (0.4 g) under intensive culture system. They were fed with a formulated diet with the composition of Casein, Gelatin, Dextrin, Cod liver oil, Cellulose, Carboxylmethyl cellulose, Miner pre mix, Vitamin mix and Oxytetracycline. The whole mixture contain 45.8% crude protein on a dry weight basis and served for 75 days twice a day at 3% of body weight. It was noticed that all frys did not exhibit same results. Among experimental specimen Catla catla respond significantly by exhibiting least FCR value 3.735±2.293 followed by SGR 2.405±1.642 and % weight gain 34.3±13.9.
