Abstract
This study is an attempt to explore the fish diversity of the Dibru River, a vital waterway that supports both the local economy and the ecological integrity of the Dibru-Saikhowa National Park, conducted during October 2023 to May 2024. A total of 414 specimens were collected, representing 40 species across 34 genera, 18 families, and 9 orders. Of these, 37 photographs of different fish species, mostly of ornamental value, are presented to emphasize the potential of the fish resources of this river. Notably, the study records a new range extension for Pseudolaguvia vespa, documenting its presence in the Dibru River within the Brahmaputra Basin.
