  In this study gill-net selectivity for Tenualosa ilisha in the River Meghna was estimated. Traditional fishing was conducted by using gill-net with 55 mm, 65 mm and 75 mm mesh-size during August 2016 to October 2016. From the Meghna River estuary, a total of 660 specimens of T. ilisha were caught by gill-net during the study period. Mean total lengths were calculated as 24.7 ± 2.7 cm, 31.2 ± 2.78 cm and 34.33 ± 4.69 cm for 55 mm, 65 mm and 75 mm mesh sizes gill-net respectively. Selectivity analysis indicated an optimum catch length of 260.50 mm for the 55 mm mesh size, 328.36 mm for the 65 mm mesh size and 370.99 mm for the 75 mm mesh size gill-nets. The catch percentage of Hilsa by 55 mm, 65 mm and 75 mm mesh size gill-net were 38.78%, 39.10% and 22.12% respectively. The majority of fishes caught by these three-mesh size gill-net were found to be matured. Theref.. View More»
