Tor putitora, the Putitor mahseer, Himalayan mahseer, or golden mahseer, is an endangered species of cyprinid fish that is found in rapid streams, riverine pools, and lakes in the Himalayan region and southern Asia, ranging from Iran south to Sri Lanka, and east to Thailand. It is a popular gamefish, the largest species of mahseer, and can reach up to 2.75 m (9.0 ft) in length and 54 kg (119 lb) in weight, though most caught today are far smaller. It is threatened by habitat loss, habitat degradation and overfishing, and it already has declined by more than an estimated 50%. This omnivorous species is generally found near the surface in water that ranges from 13 to 30 °C (55–86 °F).
Its caudal, pelvic, and anal fins show tint of reddish-golden color. While the body above its lateral line is generally golden in color at adulthood, the gold color might be absent in young specimens.
The breeding phenology of Golden mahseer in lesser himalayan region of India appears to have undergone a transition over the last 10 decades. Even after a probable reduction in duration of breeding season and shift (delay) in onset of breeding in Golden mahseer population during 1911–1981, some stabilization in breeding phenology appears to have been attained since 2000s. It is predicted that the species appears to be continuously adapting to changing climate in lesser Himalayas.
