Fish Fauna of the Dibru River- A Tributary of the Brahmaputra River, Dibrugarh District, Assam, Northeastern India, with a new range extension record of Pseudolaguvia vespa

Abstract

Fish Fauna of the Dibru River- A Tributary of the Brahmaputra River, Dibrugarh District, Assam, Northeastern India, with a new range extension record of Pseudolaguvia vespa Kensibo Pamai1, Shantabala Devi Gurumayum2 and Bitu Rai1 ORCİD: 0009-0008-7411-6221; 0000-0003-0917-8158; 0009-0009-3194-3849 1Department of Zoology, Patkai Christian College (Autonomous), Chümoukedima-Seithekema, Chümoukedima District, Pin-797103, Nagaland, India 2Zoological Survey of India, Arunachal Pradesh Regional Centre, Senki Valley, Itanagar, 791113, Arunachal Pradesh, India 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.
