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. Its native range is within the basins of the Indus, Ganges and Brahmaputra rivers.[1] It was reported to be found in the Salween river, the natural border between Thailand and Myanmar as well, but the number is very rare, only three times in 28 years.[2]
This omnivorous species is generally found near the surface in water that ranges from 13–30 °C (55–86 °F).[3] It is a popular gamefish, once believed to be 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.[4]
The official IGFA (International Game Fishing Association) All-Tackle World Record is 29.94kg (66lb), caught by British angler - Greg Iszatt from the Mahakali River in June 2017. Greg Iszatt was assisted by mahseer guide - Christopher Oldmeadow.
Its caudal, pelvic, and anal fins show tint of reddish-golden colour. While the body above its lateral line is generally golden in colour at adulthood, the gold colour might be absent in young specimens.
Hamilton's original description says "The head is blunt, oval, small, and smooth". He goes on to say "The mouth is small" and "the lateral line is scarcely distinguishable".[5] However, the largest head of any mahseer species, with a large mouth and prominent lateral line stripe, are features considered to be important in the correct identification of this species.
The Himalayan Golden Mahaseer is the National fish of Pakistan.[6][n 1] It is also the state fish of the states of Arunachal Pradesh, Himachal Pradesh, Uttarakhand, Madhyapradesh and the UT of Jammu and Kashmir.[7]
Nobel Prize Winner for Literature - Rudyard Kipling, wrote: "There he met the mahseer of the Poonch, beside whom the tarpon is a herring, and he who catches him can say he is a fisherman.” (Rudyard Kipling - "The Day's Work" 1898 - "The Brushwood Boy" 1899).
It is threatened by habitat loss, habitat degradation and overfishing, and it already has declined by more than an estimated 50%.[1] The prospect of large-scale dam building across the distribution range gives cause for concern reflected by the current Red Listing status.
Most researchers believe this fish is in a population decline, hence the Red Listing status of Endangered. Some, however, have noted that Tor putitora is "quite abundant",[8] which also raises questions about the status of ongoing stock augmentation programmes.
Recent releases of artificially bred stock have been into the Irrawaddy River basin in Nagaland, India and, through the Indo-German Biodiversity Programme [9] releases into the Hira Bambai reservoir and small streams around Melghat Tiger Reserve, part of the Tapti River basin.[10] The effect of releasing fish from a different river basin, well outside its native range is uncertain. That these fish are being released over a ten-year period, with as many as 10,000 in each batch, must be considered a huge threat to the native mahseer and other fish species.[11] According to Dr Ogale, former scientist leading the fish breeding programme for Tata Power: "When these mature, there will be more fingerlings which will be then introduced in river Tapi".[12] River Tapi is a west-flowing river of the central Indian state of Maharashtra. Golden mahseer from Lonavala hatchery in Maharashtra, India were supplied to the government of Papua New Guinea[13][14] where the fish escaped into the local Sepik river system after release into the Yonki reservoir. There are fears about the decline of native species following these introductions.[15]
