Abstract: The goal of the current study was to evaluate the catch per unit effort (CPUE) of various fishing nets, their catch composition, and the identification of fish biodiversity used in the Chandpur area's Lower Meghna River. According to the survey, six groups of fishing nets with mesh sizes ranging from 0.0 cm to 12.7 cm were used in the Chandpur district. Near about 0.0 cm to 0.3cm meshed set bag net, seine net and barrier net were found as detrimental to the fisheries community and the study also observed around all size groups of fishes were caught by these nets. The catches of multi-meshes set bag net were found highest 7.87±0.74 kg/fisherman/day in February followed by barrier net 5.41±0.32 kg/fisherman/day in January, gill net 5.21±0.45 kg/fisherman/day in June, others net 3.79±0.47 kg/fisherman/day from in November, seine net 3.24±0.24 kg/fisherman/day in January and 3.09±0.15kg/fisherman/day from drag net in December. The highest CPUE (kg/fishermen/day) was observed in the dry season (4.25±0.41) followed by monsoon (3.83±0.5). The ANOVA revealed a significant difference between the six groups of fishing nets used in the Chandpur area (p
