Abstract: The study was aimed to find out the status and decline causes of fish diversity of Ichanoi Beel of Bangladesh. A total of 62 fish species were identified under 10 orders of which 35.48% was identified as Cypriniformes, 25.81% as Siluriformes, 20.97% as Perciformes, 6.45% as Channiformes, 3.23% as Osteoglossiformes; and the rest the five orders viz. Anguilliformes, Cyprinodontiformes, Synbranchiformes, Beloniformes and Tetraodontiformes as 1.61% of the total catch. The availability status was remarked in four categories and obtained as available (46.77%), seasonal (8.06%), rare (6.45%) and extremely rare (38.71%). Decline causes like excessive use of fertilizer and pesticides, over fishing, climate change effects were observed as major threats for fish diversity. About 24 species were found inclined to extinct in near future that recorded as extremely rare in the study area. The present work recommends minimizing of all these impediments to save the fish diversity of Ichanoi Beel.
