Induced breeding is a technique to stimulate ripe fish breeders by different inducing agents to breed in captive condition. Four fiberglass reinforced plastic (FRP) carp hatchery units (technology developed by ICAR-CIFA) were supplied, installed and operated in cyclone, Phailin-affected four adopted villages, namely Ambapur and Sindhukhalli in Digapahandi Block, Sujanasahi in Khallikote Block and Daseipur in Sanakhemundi Block of Ganjam District, Odisha for carp seed production. In the established hatchery units induced breeding of Indian major carp, rohu (Labeorohita) was successfully conducted by synthetic hormone ‘Ovatide’ in the monsoons of 2018 and 2019.Induced breeding programmes were conducted for two times at Ambapur Village and four times at Sindhukhali Village in 2018; and four times at Ambapur Village, five times at Sindhukhali Village, three times at Sujanasahi Village and one time at Daseipur Village in 2019. Total 21 lakh rohu spawn (7.5 lakh in Ambapur and 13.5 lakh in Sindhukhali) and 121 lakh (41 lakh in Ambapur, 49 lakh in Sindhukhali, 27.5 lakh in Sujanasahi and 3.5 lakh in Daseipur) was harvested in 2018 and 2019, respectively. Spawning was observed after a latency period of 330-420 minutes; fertilization rate was 84.5-95.0% under the temperature range of 26.5-33.2 0C and spawn production was 0.78-1.16 lakh/kg body wt. of female rohu in the field conditions.
