A Study on Present Status, Abundance and Threats of Fish Diversity in West Bengal

The present examination was led in the water groups of East Kolkata Wetlands to create an essential database on fish decent variety of West Bengal, India. 71 indigenous fish species having a place with 27 families were distinguished. The family Cyprinidae spoke to the biggest decent variety obliging 14 genera and 23 species. As per IUCN (International Union for Conservation of Nature) and CAMP (Conservation Assessment and Management Plan), the protection status of the fishes are recorded as 1 (1%) species as Critically Endangered, 4(6%) species as Endangered, 16 (22%) species as Vulnerable, 21 (30%) species as at Lower Risk Near Threatened, 21 (30%) species as Lower Risk Least Concerned, 1(1%) species as Data Deficient and 7 (10 %) species as Not Evaluated. About 59% fish species are close to dangers, defenseless and jeopardized in this locale. Among the fish decent variety of East Kolkata Wetlands58 species were indigenous species and 13 species were fascinating. It is closed, that anthropogenic weight emerging out of modifications of wetland living spaces to rural grounds, territory obliteration, over abuse, wanton pulverization, sea-going contamination, ailment, extraordinary species present and by and large absence of consciousness of biodiversity significance, nonattendance of appropriate arrangement are contributing a lot to such disturbing defenselessness of the rich fish decent variety in their regular environment. Mindfulness programs among the angler, exacting restriction on isolating of huge water bodies into divided little lakes, continued drying of development lake, loss of characteristic rearing ground for imperiled species, utilization of bug sprays and pesticides in lakes to control undesirable species.
