Field trials for maximization of fish production in composite carp farming in mid hills of Uttarakhand

Author(s): VK Singh, KS Mehta, Rikhi S Chauhan
Abstract: Present trials were undertaken to optimize fish stocking density, size, ratio and time of stocking in ponds to obtain maximum fish production in mid hill conditions. In experimental trial-1, fishes were stocked @ 100 (T1), 300 (T2), 500 (T3) and 700 no/100 m2 (FP) ponds. Among the treatments, maximum fish growth was achieved in pond T1 (389.0 g) followed by T2 (297.5 g), T3 (186.65) and FP (123.85 g). However, highest fish production was achieved in Pond T2 (41.65 kg/100m2) having fish stocking density 300 no/100 m2 and lowest fish production was recorded in FP pond (27.82 kg/100m2) at fish stocking of 700 no/100 m2. In experimental trial-2, highest fish production (62.90 kg/100m2) was recorded in ponds stocked with 10-12 cm size fish seed @ 300 no/100 m2 in the ratio of 30:40:30 silver carp, grass carp and common carp, respectively, stocked in March and harvested after 12 month of growing period in February.
