Abstract: Availability of fish seed in terms of quality as well as quantity has been a major constraint for the farmers involved in fish farming since long in Ganjam District, Odisha. Three Community Development Blocks of the district namely, Khallikote, Kukudakhandi and Digapahandi were surveyed for selection of rural ponds for carp seed rearing programme. Advanced IMC fry (Catla catla 17-24 mm & 0.03-0.104 g, Labeo rohita 14-18 mm & 0.02-0.037 g, and Cirrhinus mrigala 16-22 mm & 0.02-0.051 g) of 66,000 nos. were procured from Orissa Pisciculture Development Corporation (OPDC) Hatchery, Digapahandi, Ganjam and were stocked in three ponds with total area of 4.4 ha (with 70% WSA) of the beneficiaries on 31 August 2017. The stocking density was 15,000 nos/ha pond area and the ratio of stocking was catla: rohu: mrigal: 1:2:1. The fry were reared for 40-43 days. In Digapahandi Block the farmers used rice bran and sesame oil cake in the ratio 1:1 as supplementary feed and in other two blocks rice bran and ground nut oil cake in the ratio 1:1 was used. Growth of all the three species was better in Digapahandi Block (C. catla 57-64 mm & 2.02-2.68 g, L. rohita 45-52 mm & 1.67-2.52 g, and C. mrigala 36-47 mm & 0.53-0.75 g) than other two blocks. The average survivability achieved in this scientific IMC seed rearing practice from advanced fry to fingerling stage in Ganjam District was 65.15%, being highest in Digapahandi Block (70.83%). Before adoption the productivity of ponds in terms of plankton volume was 0.4-0.5 mg/50 liter pond water and this was increased to 0.8-1.8 mg/50 liter with adoption of better management practices (BMP) during seed rearing programme.
