Sep 8, 2017 | Research & Conservation

Mahseer Trust Officer – India Science Lead, Rajeev Raghavan, has recently co-authored a new scientific paper with Neelesh Dahanukar (IISER Pune) and Ralph Britz (Natural History Museum, London), to clarify the identity of Tor mosal, a mahseer of the Himlayan region.

The Mahseer Trust team and the wider network of collaborators believe that species integrity is an essential part of ecosystem conservation. Before we can protect an ecosystem, there is a need to have the best possible understanding of the species involved, in order to both understand what we are trying to conserve, and the symbiosis between the various flora and fauna. The many mahseer species of India are still not fully understood, so it is a great step forward every time new information helps to unlock another piece of the puzzle.

Hamilton (1822) described Cyprinus mosal, now assigned to the genus Tor, from the ‘Kosi’, a tributary of the Ganges. The fact that two Gangetic tributaries with the name Kosi exist, has resulted in confusion in the Indian ichthyological literature and beyond regarding the type locality of Hamilton’s T. mosal. A critical review of Hamilton’s treatise on the fishes of the Ganges, as well as several other works by and on Hamilton, revealed that T. mosal was collected in and described from the Kosi (=Koshi), a Gangetic tributary that originates in the northern slopes of the Himalayas in the Tibet Autonomous Region and drains the southern slopes of Nepal and Bihar (India); and not from the more western Gangetic tributary by the same name flowing through Ramnagar in Uttarakhand State, India.
