Quarterly field sampling was conducted from 2016 to 2020 to understand the distribution and current status of IUCN Red-listed fish species along the entire stretch of River Ganga. During the study, 18 fish species belonging to 8 orders and 12 families were recorded under the IUCN Red list. Fishes belonging to the family Synodontidae contributed highest among the threatened group. The status of fish species have been categorized on the basis of IUCN Red list. Among 18 fish species, Clarias magur and Tor putitora were categorized as endangered, whereas Wallago attu and Schizothorax richardsonii were categorized as vulnerable. The present study suggests the necessary management plans and conservation strategies for these IUCN Red-listed fish species of River Ganga.

Abstract


Quarterly field sampling was conducted from 2016 to 2020 to understand the distribution and current status of IUCN Red-listed fish species along the entire stretch of River Ganga. During the study, 18 fish species belonging to 8 orders and 12 families were recorded under the IUCN Red list. Fishes belonging to the family Synodontidae contributed highest among the threatened group. The status of fish species have been categorized on the basis of IUCN Red list. Among 18 fish species, Clarias magur and Tor putitora were categorized as endangered, whereas Wallago attu and Schizothorax richardsonii were categorized as vulnerable. The present study suggests the necessary management plans and conservation strategies for these IUCN Red-listed fish species of River Ganga.
