Abstract: A study was conducted to assess the degree of indiscriminate killing of Pangasius pangasius (Hamilton, 1822) [6] in upper and lower Meghna and Padma river of Bangladesh. A total of 08 study areas were pre-selected in the rivers during peak killing season from November 2012 to May 2013. Three types of fishing net such as gill net (Current jal), set bagnet (Behundi jal) and barrier net (Charghera jal), and two types of fishing trap pangas chai and hook line (Borshi) were found to be involved in arbitrary killing of pangas fry in open water habitat. Among the arbitrary gears pangas chai has shown the highest efficiency in catching juvenile pangas in different sampling locations. In Barisal, Monpura and Hatia the highest CPUE of pangas chai were 81, 101 and 100 kg/haul, respectively in the month of May and the lowest CPUE was 25, 23 and 19 kg/haul, respectively in the month of January. The maximum average CPUE of pangas chai was found 48.14 kg/haul in Monpura and lowest average CPUE was 22.67 kg/haul in Haimchar. More intense use of pangas chai was found in Barisal, Monpura and Hatia. The highest average length and weight of juvenile pangas was 22.22 cm and 77.51 g, respectively while the lowest average length and weight of juvenile pangas was 15.71 cm and 43.1 g, respectively. The highest CPUE of pangas chai was found 101 kg/haul in May in Monpura by 100 kg in Hatia.
