Abstract: One unit of FRP carp hatchery with one breeding pool, one hatching pool, one egg/ spawn collection tank and one plastic made overhead tank of capacity 2000 litre was installed and operated at Bali Island, Sunderban, West Bengal during 2014-15. During July - August, 2015 for the first time the successful induced breeding of Indian major carps (rohu, Labeo rohita and catla, Catla catla) and Indian minor carp (bata, Labeo bata) was conducted in the established hatchery and 18.5 lakhs spawn was harvested. In this experiment spawning fecundity of rohu was found to be 0.88-1.0 lakh, catla 0.95 lakh and bata 1.1-1.3 lakh egg/kg bodyweight of female fish. Time for completion of egg hatching was found more or less similar in rohu 920-970 minutes, catla 965 minutes and bata 940-990 minutes. Percentage of spawn survival from egg release was calculated to be 85.5-92.5% in rohu, 84.5% in catla and 86.5-90% in bata. Spawn production per kg female body weight (lakh) was found similar for all the experimented fishes i.e., rohu 0.74-0.88 lakh, bata 0.86-1.2 lakh and catla 0.66 lakh. Water parameters like pH, total alkalinity and total hardness were analyzed by APHA 2005 method in the laboratory at ICAR-CIFA, Kalyani, West Bengal and water temperature was measured by temperature probe.
