The study, which took place from April 2022 to September 2022, was undertaken to comprehensively investigate the ichthyofaunal diversity within the stretch of Damodar River located in Dhanbad district of Jharkhand. The meticulous examination of the river's fish fauna has unveiled a total of 35 distinct species, distributed across 30 genera, belonging to nineteen families and ten orders. Notably, the family Cyprinidae emerged as the dominant taxonomic group, boasting eight species, with Donionidae closely following, comprising five species within the study area. Of particular concern is the conservation status of these species, with one being categorized as endangered, another as near threatened, and three more falling into the vulnerable classification. These findings underscore the pressing need for concerted efforts in the conservation and management of this invaluable aquatic ecosystem.
