The present survey disclosed the available fish biodiversity and the gears used for fishing in the Chinadi beel, Narsingdi, Bangladesh, for a certain period. Data was collected through face to face conversations using a well-structured questionnaire and cross-checked. About 51 species of fish under 7 orders and 19 families were found. The dominant order was found jointly for Cypriniformes (29.41%) and Siluriformes (29.41%). About 39 least concern (75%), 5 vulnerable (9.62%), 6 near threatened (11.54%), and 1 not evaluated (1.92%) species were observed. Fifteen different types of fishing gears (8 major categories) are used for fishing by the fishermen, of which seine net was the most leading gear. Most of the gears are banned for a period due to its unauthorized mesh size. The price of fishing gears was ranged from 2501,00,000 Tk, of which the highest price was for seine net. The uppermost catch per unit effort (CPUE) was found for ber jal that was 15-18 kg/day. Most of the fishing gear was operated throughout the year, but limited in the dry season. However, the variety of fish abundance and species diversity is declining day by day in this beel. To protect the fish diversity of the Chinadi beel, it is recommended to establish effective fishery management practices, monitoring overfishing, and awareness of fishermen is highly recommended.
•The beel has a rich fish biodiversity and important for fisheries resources in the middle-east part of Bangladesh. About 51 species of fish under 7 orders and 19 families were found. Fifteen fishing gears (8 major categories) are used for fishing by the fishermen.
•Now-a-days, biodiversity of fish was decreased due to over fishing, water pollution, heavy siltation, rapid urbanization and intervention of human.
