Abstract: The study was carried out in 03 selected farmer’s pond at Kaliganj upazilla (sub district) under Lalmonirhat district during June to September 2019 having area of pond 0.30 acre each. Before stocking, ponds were dried and cleaned for weed and unwanted aquatic animals. The dried ponds were treated with limed at the rate of 250 kg/ha. Five days after liming, water was supplied from shallow tube well to the ponds and filled up to the depth of 1.5 meter. The fry of Koi (A. testudineues) with Shing (H. fossilis) and Rajpunti (P. gonionotus) were stocked at the stocking density of 200000; 75,000 and 12500/ha, respectively. After stocking, fish were fed with supplementary feed (30% crude protein). Fish sampling were done at monthly interval to know the fish growth as well as feed adjustment. After four months rearing, fish were harvested by repeated seine netting. Total bulk weight and number of fish from each pond was recorded. The results showed that Koi reached the harvesting weight ranged of 127-136g. While harvesting weight range of Shing and Rajpunti were found to be 29-32g and 234-250g, respectively. Based on the number of fish harvested at the end of the experiment, survival ranged from 83 to 89%. Total production of Koi (A. testudineues) with Shing (H. fossilis) and Rajpunti (P. gonionotus) as recorded in trial ponds were 23318, 1976 and 2562 kg/ha, respectively. Total production of fish as recorded in trial ponds were 27856 kg/ha.
