Abstract: Present study was carried out to evaluate the growth performance of polyculture Heteropneustes fossilis in different stocking density in seasonal ponds of greater Northern region, Bangladesh for a period of 150 days from 30 March 2016 to 30 August 2016. Nine uniform earthen ponds (10decimal) were divided in to three treatments. Three stocking densities of H. fossilis such as 1,23,550 (T1), 148260 (T2) and 172970 ha-1 (T3) were tested with three replications each with C. batratus, O. niloticus and B. gonionotus commercial pelleted fish feed containing 30% crude protein were supplied 8-6% of the body weight of H. fossilis. Sampling of the experimental fishes along with the monitoring of the water quality parameters were measured on fortnightly basis. Over the study period, all the recorded water quality parameters were founded within the acceptable range suitable for fish culture. At the end of the culture period harvested weight of H. fossilis were found 65.11± 1.11, 58.0±2.00 and 48.0±0.58 g where T1 permit significantly (P<0.05) better growth performance followed by T2 and T3 Significantly (P<0.05) with better nutrient utilizations FCR in T1 (2.63) followed by T2 (2.84) and T3 (3.08). Significantly higher survival (%) of the fishes were recorded in T1 (77.93±1.63) followed by the T2 (76.12±0.62) and T3 (72.71±0.14). Considering the survival highest gross production (kg ha-1) in T2 (7793.82) followed by T1 (7593.39± 235.3) and T3 (6981.91±62.2). However, BCR in (T1)1.6933 was found to be more efficient and profitable followed by (T2) 1.4923 and (T3)1.3207). Based on the present findings, polyculture H. fossilis might be suggested to the fish farmer as a potential adaption option to utilize the seasonal water bodies. The polyculture technology of shingi may also help to meet the dietary needs and improve the socio-economic status of the people of Bangladesh
