Abstract: India is endowed with vast expanse of freshwater resources which can be broadly put under two categories depending on basic ecological consideration. They are ponds and lakes and streams and rivers. In Assam alone nearly one lakh hectare of water spread area is covered under beels. Assam is recognized as one of the hotspots of freshwater fish diversity. Biodiversity and its conservation are regarded as one of the major issues of enabling sustainable use of natural resources. The wetlands are providing ecological services to the fringe villages mostly in the form of fishery. Thus, documentation of biodiversity and habitat analysis is the need of the hour for framing out management strategies. A survey was conducted on the Nitai beel of Kamrup district since September 2017 till Oct-2020. Its geographical location falls under 910 31´06´´E longitude & 26011´52´´N latitude. Situated on the North-west of Karmrup district lies the Nitai beel, which falls under Hajo revenue circle. The beel is almost 05 km far from Sualkuchi town. Primary data were collected by visiting the studied area twice a month. The local people.....
