A 90 days feeding trial was conducted in cages to test the efficacy of formulated sinking feed in cages in response to environment and domestication process in Labeo rohita. The experiment was conducted in lentic environment of Maithon reservoir of river Damodar, Jharkhand and at lotic environment (1m/sec) in a rivulet of river Ganges at Balagarh, Hooghly district, West Bengal involving normal breed of Labeo rohita and Jayanti rohu (Labeo rohita), a stock of genetically improved strain through selective breeding. The survival, growth performance, feed utilization, nutrient retention and biochemical composition of Labeo rohita (normal rohu and jayanti rohu) were assessed. Overwintered seeds of normal rohu with average size of 31.3g and Jayanti rohu with average size of 8.05g were stocked in cages @ 2nos/m3 in duplicate. The fishes were fed with experimental sinking diet (Crude protein: 28.4%; Crude lipid: 5%) @ 5% of the body weight twice a day at two equal instalments at 10.00 hr and 16.00 hr during the feeding trial. The growth of jayanti rohu (% weight gain) was 2.7 times higher in cages installed in lotic water compared to lentic water after 90 days of feeding trial. While, the growth (% weight gain) of normal breed rohu was 2.15 times higher in flowing water as compared to stagnant water. The results clearly indicated the role of environment and domestication process on the growth performance, conversion efficiency and flesh quality of carps in cage farming. The better results were observed with Jayanti rohu and in flowing water which will be helpful in invoking the growth of carps in cages.
