A culture experiment was conducted to see the growth and production performance of Pabda (Ompok pabda) with native Magur (Clarias batrachus) at different stocking densities in poly-culture at the Pond of BAPARD campus, Gopalganj from 16 August to 16 November. The size of ponds were 10 (T1) and 10 (T2) decimal with an average depth of 5 feet. Two different stocking densities were tested, namely treatments T1 (250 fish /decimal, 200 Pabda and 50 native magur) and T2 (300 fish /decimal, 250 Pabda and 50 native magur). Nourish feed was used in all treatments two times daily (only for Pabda) from the beginning of the fry stocking. The initial weight of Pabda and Native Magur were 1.0±0.01g and 2.5±0.01 g respectively. The initial length of Pabda and Native Magur were 4.5±0.02 and 5.2±0.02 cm respectively. The average highest final weight gain of Pabda was (24.70±2.50 g) observed in T1 and followed by T2 (20.90±3.40 g). Similarly, the average highest final weight gain of Native magur (145.30±27.75 g) was observed in T1 and followed by T2 (142.05±27.95 g), respectively. The survival rate of the stocking Pabda and Native magur were recorded 74.73 and 54.73 % in T1; 65.12 and 45.12 in T2 respectively. Fish production (Pabda+Native magur) in T1 and T2 were 7.65 and 6.60 kg/decimal/120 days, respectively.
