In the present study, the effects of environmental pollution on aquatic vertebrate biodiversity were studied and inventory of vertebrate fauna of Hub Dam was prepared. During the study, no adverse effects of environmental pollution were found on the aquatic biodiversity except for some minor toxic effects due to trace metals in water. As many as 16 species of mammals, 160 species of birds, 23 species of reptiles, 03 species of amphibians, 29 species of fishes, and 25 species of plants were recorded from the Hub Dam area. There are no serious effects of pollution on the vertebrate biodiversity of the wetland. All the physico - chemical parameters were recorded as per limits of WHO Standard. There is a serious decline in water bird population but these are mainly due to social disturbances. Areas near spillway, main dam area, agriculture land/ shallow water, and Hub Canal are the prime habitats of birds in the wetland. The research techniques and information are helpful for graduate and research students of Biological Sciences, Environment and wetlands managers.
