Abstract: Jemamantadeipur and Kantabada Villages of Begunia Block, Khordha District, Odisha were adopted in a model village cluster approach in the Department of Biotechnology (DBT), Government of India funded and ICAR-CIFA operated project for demonstration of freshwater aquaculture technologies and livelihood development of the adopted beneficiaries. One fibreglass reinforced plastic (FRP) carp hatchery of 1.0 million seed production per operation in four days capacity was installed and operated in Kantabada Village from 2015 monsoon. Carp brood rearing was done in one 0.2 ha pond and seed rearing practices were undertaken in two ponds of 0.2 ha each at Kantabada and 0.4 ha at Jemamantadeipur. Around 50-60% survival was achieved for each stage of carp seed rearing from spawn to fingerling stage during the demonstration period (2015-2016). One community pond of 2.4 ha with average water spread area (WSA) of 1.4 ha was taken for demonstration of grow out fish culture in Jemamantadeipur Village. Total 76 beneficiary families, mostly tribals from both the villages were adopted in the project. Grow-out carp culture operations were carried out in the community pond of Jemamantadeipur Village in two phases in two years. The first phase was during November, 2015 - June, 2016 and the second phase during September, 2016 - May, 2017. The species cultured were catla, Catla catla; rohu, Labeo rohita; mrigal, Cirrhinus mrigala and grass carp, Ctenopharyngodon idella @ 1:2:1:1 ratio and were stocked @ 5,000 fingerlings/ha. The fish production was enhanced from the pre-adoption level of 450 kg/ha/yr to a range of 3,096-3,610 kg/ha/yr. The profit share per beneficiary family of Jemamantadeipur Village was calculated to be Rs. 3,200/= approximately per year from fish culture operations. The present intervention of ICAR-CIFA revealed that the fish production can be increased from the community pond through integrated use of seed, feed and fertilizer resources as inputs. Emphasis was given for improving the knowledge and skills of the farmers for adoption of scientific fish farming practices in their locality for better economic returns.
