Study of aquatic biodiversity and correlation with physical parameters of Jalangi river

The present study is concerned to assess the present status of aquatic biodiversity and its correlation with few physical parameters of river Jalangi. The study shows more than 35 species of freshwater fishes, eight species of zooplanktons, four species of dragonflies and two species of damselflies, few species of mollusks, which reflects that the river Janangi is full of diversity with respect to flora and fauna. The river is full of eel grass. River Jalangi is also a habitat of water striders, few crab species and aquatic snakes. In few areas, pollution may affect the present ecological status of Jalangi River in near future. This preliminary study identifies the overall biodiversity status of Jalangi. However, more work in this direction is required to make complete database on floral and faunal diversity of this river.
