Golden Mahseer goes by many names, such as the Himalayan mahseer, Putitor mahseer, king mahseer, and mighty mahseer. Its scientific name is Tor putitora.

Mahseer is the union of Mahi (meaning fish) and sher (meaning tiger). That's why it is also referred to as the tiger of the water or the tiger among fish.
