Exploring the Rich Diverse: Freshwater Fish Diversity and Bionomics in the Sundarbans, India

The Sundarban is a mangrove area in the deltaformed by the confluence of the gangas brahmaputra and meghna river in the Bay of Bengal. The hooghly river in india state of West Bengal to the baleswar river in bangladesh. It comprises closed and open mangrove forests agriculturally used land, mudflats and barren lands. It is intersected by multiple tidal streams and channels. Four protected area in the Sundarbans are enlisted as UNESCO WORLD HERITAGE SITES, Sundarbans national park,Sundarban west, east and south wildlife santuaries. The bengali name Sundarban is beautiful forest. It may have benn derived from the word sundari, the local name of the mangrove sp Heritiera fomes. There many biodiversity like 453 faunal wildlife, including 290 birds,120 fish, 42 mammal, 35 reptiles and 8 amphibians. The goal of this review paper is discussing about freshwater fish diversity and its bionomics in Sundarban delta. Also about the a brief description of study area (Sundarban) encompassing definition of a mangrove ecosystem, importance of mangrove ecosystem, area and distribution of Sundarban; Indian Sundarban – area, location, fisheries related activities; importance of studying fish diversity. And try to generate a data base on some of the life history parameters and their conservation status and atlast study threats associated with fish diversity measures for sustainable fishery.
