A preliminary study was conducted in the Sirum River, a tributary of the Siang River, located in the easternmost part of Arunachal Pradesh. A review of existing literature indicated a lack of systematic fish assessment in this river, which this study aimed to address. Fish sampling was carried out twice a month from October 2023 to September 2024 at three sites. Fifty four species belonging to four orders, 15 families, and 38 genera were recorded. Cypriniformes comprised 35 species, Siluriformes 14, Anabantiformes seven, and Synbranchiformes one species. Three species were classified as Endangered, two as Near Threatened, four as Vulnerable, 31 as Least Concern, four as Data Deficient, and 10 as Not Evaluated. Representative images of threatened and economically important fish species are included to aid in visual identification and documentation.
