Analytical Study on Threats and Challenges of the Fish Biodiversity of West Bengal

Investigations and germplasm inventories of fish biodiversity in the amphibian water groups of India are as a rule dynamically refreshed and broke down with a few new revelations in any case; a well-characterized number of existing fish species at territorial/state level stays to be resolved. Of the all out freshwater fish decent variety of the nation, imperilment ranges from 10-13% shows across the board and inescapable corruption of sea-going freshwater fish living spaces. The State of West Bengal is supplied with 7.5% of the water asset of the nation and that is getting progressively rare with the uncontrolled development of populace, extension of water system organize and formative needs. Worry over declining harvests and a conspicuous decrease in biodiversity of fish species has prompted a progressively all encompassing way to deal with fisheries the board and research. The state is blessed with immense sea-going assets as streams, lakes/tanks, store, beel and hog, salty water fishery and furthermore prevailed by a few wetlands. Scrutiny of writing uncovers that few dispersed data on fish biodiversity of West Bengal is accessible. In the present audit, inside and out, 190 local freshwater fish species were recorded from the West Bengal contributing about 23% of the Indian freshwater angles. The displayed survey featured a succinct audit of Indian fish biodiversity, examine the dangers, challenges, protection projects and offer trust later on for the country's endangered freshwater fish supportability of the West Bengal. Saving the biodiversity of these fishes and simultaneously dealing with their misuse in a maintainable manner is a troublesome exercise. The differing collections of freshwater types of the state ought to be focused by all who have a stake in our freshwater legacy. This paper features the example of freshwater fish biodiversity in numerous points of view, usage, dangers and examines the administration systems to be actualized for the preservation of freshwater fish decent variety in the state.
