This study examined the fish fauna of Chinadi Beel in Bangladesh in terms of diversity, quantity, and state of conservation. A pre-tested questionnaire and a direct catch evaluation survey were employed to conduct the study in the beel. In the examined beel, a comprehensive count of 3,360 fish specimens, encompassing 52 distinct fish species from 8 orders and 19 families, was documented. Cypriniformes was identified as the dominating order among the 8 orders examined, accounting for 51.49% of the total. Out of 52 fish species about 31 least concern (59.61%), 8 endangered (15.38%), 6 vulnerable (11.54%), 6 near threatened (11.54%) and 1 critically endangered (1.92%) species were observed according to the International Union for Conservation of Nature. The study utilized population diversity indices, specifically the
Shannon-Weiner diversity index (H'), Margalef species richness (d), Pielou's evenness index (J'), and Simpson dominance index (c), to assess the species diversity, richness, and evenness of fish which value were found to be 2.50, 4.30, 0.90, and 0.30, respectively. Chinadi Beel has the capacity to function as a significant reservoir of fishing resources and a repository of genetic information for many fish species. However, the present study emphasized several anthropogenic and environmental issues, such as unregulated fishing, agricultural pollutants, illegal or harmful fishing, the construction of infrastructure for development, and climate change. Hence, it is highly recommended to implement ecosystem-based fisheries management that actively involves the local population in order to guarantee the long-term preservation of these water bodies.
