Abstract: An experiment was carried out in six nursery ponds of 5.0 decimal each with 4 days old stinging catfish shing (Heteropneustes fossilis) spawn at three stocking densities viz. 2, 3 and 4 million ha-1 for the period of 4 weeks from 01 June to 28 June 2017. MEGA pre-nursery and nursery feeds were provided three times daily at the rate of 15% for the first one week and were decreased by 1% every week thereafter. Growth of fry was inversely related to stocking densities. Similar inverse relation was also observed in case of survivals, which were 55.74, 50.20 and 34.41% at 2, 3 and 4 million spawn ha-1 stocking densities, respectively. The final length, final weight and survival rate of H. fossilis fry were significantly (P<0.05) higher in T1 than those obtained from T2 and T3, respectively. Considering the highest gross and net production the stocking density applied in 3 million spawn ha-1 found best in primary nursing which a better production to fish farmers but more research still needed to further optimize stocking density of H. fossils.
