In a significant scientific discovery, a group of researchers has identified a previously unknown freshwater fish species in Odisha’s Mahanadi River. This newly found species, named ‘Awaous Motla,’ has been unveiled as part of an ongoing research project conducted by the zoology department of Berhampur University and the Zoological Survey of India, Gopalpur, funded by the Department of Science and Technology of the Odisha government. Characterized by its vibrant yellow-colored body and a fleshy upper lip, specimens of this fish were collected from the Mahanadi River near Sonepur and the Boudh bridge in June 2022. Professor Jaya Kishor Seth, the principal investigator of the project and a zoology professor at Berhampur University, collaborated with Anil Mohapatra of ZSI’s Estuarine Biology Regional Centre and an Australian scientist to conduct a comprehensive study of the specimens. Their research established that this species is entirely distinct from others within the genus.

Local fishermen in the Sonepur region have traditionally named this fish ‘motla.’ It belongs to the ‘Awaous’ family (Oxudercidae) and is consumed by locals both in its fresh and dried forms. The fish is particularly valued, with local fishermen selling it for Rs 600 per kilogram when fresh and Rs 800 per kilogram when dried. Seth emphasized the importance of long-term research to understand various aspects of this newly discovered species, including its migration patterns and nutritional value, which contribute to its relatively higher market price compared to other locally available fish species. This discovery sheds light on the rich biodiversity of Odisha’s aquatic ecosystems and highlights the need for continued exploration and conservation efforts.
