Abstract: Scientific demonstration of freshwater aquaculture technology was conducted in an area saturation mode in the ponds of Jamushahi Cluster of Daspalla Block, Nayagarh District, Odisha for fish production, livelihood and nutritional security of tribal farming community of that area. Fourteen ponds with total water area of 4.6 ha from six villages, namely Jamusahi, Durgaprasad, Banibiri, Gundiribari, Tanganadi and Pamporada with 4,725 tribal population were adopted by ICAR-Central Institute of Freshwater Aquaculture for technology demonstration. Ponds were stocked with the fingerlings of Indian major carps (IMC) i.e., Catla catla (Catla), Labeo rohita (Rohu) and Cirrihinus mrigala (Mrigal) with size range of 40-84 mm length and 2.7-7.2 g weight, density 5,000 nos/ha and species ratio 1:1:1 in October 2015. After an average culture period of 7.5 months, the fishes were harvested during May-June, 2016. In all ponds the fish production was increased from 250 kg/ha/yr (prior to adoption) to an average of 1,157 kg/ha/yr (after adoption). Final fish harvest was ranged between 666-3,049 kg/ha/yr in all fourteen ponds of six adopted villages. Prior to adoption per capita fish availability from pond culture for consumption of the tribal population of that area was 0.39 kg/yr, which rose to 1.80 kg/yr after adoption. The present investigation of ICAR-CIFA revealed that the fish production can be enhanced through integrated use of seed, feed and fertilizer as inputs from small seasonal homestead ponds. The study also revealed that the rural economy can be strengthened through the development of small-scale fish culture enterprises.
