Assessing Freshwater Fish Biodiversity in Amuladah Beel: Unveiling Status, Threats, and Conservation Imperatives
This study aimed to assess fish biodiversity and conservation challenges in Amuladah Beel, located in Bhuapur Upazila, Tangail. The research documented 43 fish species across 9 taxonomic orders, 19 families, and 27 genera. Among these, the silver carp (Hypophthalmichthys molitrix), the bighead carp (Aristichthys nobilis), and tilapia (Oreochromis mossambicus) were identified as exotic species, while the others were native to Bangladesh. Cypriniformes and Cyprinidae were the most predominant, comprising 37% and 35% of the fish population in their respective orders and families. Carp species represented the largest group, accounting for 37% of the six most commonly recorded groups. Notably, 19 species were classified as threatened, with 9 (47%) vulnerable, 6 (32%) endangered, and 4 (21%) critically endangered. The study also highlighted the degradation of water quality due to domestic and industrial effluents, jute rotting, excessive agrochemical use, and agricultural runoff. Environmental pollution and indiscriminate fishing appear to be major contributors to the decline in fish diversity in Amuladah Beel. The findings revealed that the number of species is lower than expected based on Bangladesh’s overall fish biodiversity. To address these challenges, it is recommended to mitigate water pollution, ensure the natural flow of water, and raise public awareness. Immediate implementation of comprehensive management and conservation programs is crucial to prevent species extinction and to improve fish diversity in Amuladah Beel.
