Abstract: An experiment was carried out in nine earthen nursery ponds to assess the growth performances, survival and production of Heteropneustes fossilis fingerlings for the period of 8 weeks from June to July 2012. Three stocking densities were tested for each, viz., 2 million fry ha-1 (T1), 2.5 million fry ha-1 (T2) and 3 million fry ha-1 (T3). The growth performances and survival of H. fossilis fingerlings were significantly (P<0.05) higher in T1 than those obtained from T2 and T3, respectively. Significantly (P<0.05) the lowest feed conversion rate (FCR) was in T1 then followed by T2 and in T3. The highest number fingerlings was produced in T1 than those in T2 and T3 but showed no significant (P0.05) difference. However, the highest net benefit was in T1 where the stocking density was 2 million fry ha-1. Therefore, 2 million fry ha-1 (T1) is the most suitable stocking density for nursing of H. fossilis for better production as well as higher net benefits.
