Abstract:
KVK, Chitrakoot conducted an on farm trial on assessment of fish growth and yield under poly culture system and compared with monoculture in Chitrakoot. The monoculture of Catla (T -1) conducted at two farmers pond and composite fish culture Catla, Rohu, Mrigal (T-2) was conducted at two farmers pond for the period of 270 days from August to April 2017. The stocking density of fingerling was 10000/ha with individual weight of catla of 1.5 gm and average weight of IMC (Rohu, catla, Nain) was 1.1gm at the time of stocking. The fishes were feded with Rice bran and oil cake occasionally. The result revealed that monoculture of catla (T-1) gave the yield of 1371.13 kg /ha with average individual weight of 457.5 gm and composite fish culture IMC (T-2) gave the total yield of 1462.59 kg/ha with average individual weight of 487.12 gm in said period of time with 500 kg cow dung application on monthly basis. The benefit cost ratio of T-1 was 2.42 and T-2 was 2.52.
