The present study was undertaken on Chapai beel in Faridpur Sadar Upazila, Bangladesh to determine the fish biodiversity and to find out the problem related to fisheries biodiversity and also will make an important contribution to the development of an appropriate beel fisheries management policy in order to conserve fisheries biodiversity. A field investigation was conducted on the existing status of fishery for a period of 1 year from January to December 2020. The Chapai beel is semi-closed and has an arc-shaped water body of 84.86 ha spreading over the seven villages with covering the two unions and two Upazilas of Faridpur district. A total of 47 species (including 6 exotic species) were identified during the study. Of the 47 species, 41 were indigenous species belonging to 17 fish families, 12 different common groups and 32 fish genera; of which 25 were SIS and the remaining 16 were large fish. Cyprinidae constitutes highest number of fish population representing 15 species and shares the highest percentage (37%) among the recorded family. Barbs & Minnows was found to be the biggest group (22%) among the recorded 12 common groups. From the Chapai Beel 6 fish species were recorded as threatened which is 9% of total threatened fishes of Bangladesh. Within 41 species, 36.58% fish species were ranked as abundant followed by moderate (24.40%), low (19.51%), and rare (19.51%). The present study suggests that prudent planning, management and regulatory practices, as well as active community engagement, can positively impact fish biodiversity.
