During his work on the remains of fish bones, renowned ethnoarchaeologist Dr William R. Belcher [23] discovered that while fish, including large species like Indian major carps and various catfish, comprised a substantial element of the diets of this 3300–1300 BCE civilisation, bones of mahseer were extremely rare. [24]
Among the reasons for the species' extreme threat status is the introduction of non-native mahseers Tor khudree [4] and Himalayan golden mahseer (Tor putitora) [5] to the wider Kaveri river basin. Also endangering this species is the heavy construction of dams along the Kaveri and tributaries, as well as the use of dynamite fishing. [6]
Tor tor, commonly known as the tor mahseer or tor barb, is a species of cyprinid fish found in fast-flowing rivers and streams with rocky bottoms in India, Bangladesh, Bhutan, Nepal, and Pakistan. It is a commercially important food and game fish .
India's hump-backed mahseer is one of the world's most prized game fish, yet it was a scientific enigma.
Tor putitora, the Golden Mahseer, Putitor mahseer, or Himalayan 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 ]
As with other mahseer species, the main threats are: loss of habitat due to urbanisation, encroachment on flood plains, dam building, sand extraction and pollution. Destructive fishing methods like dynamite, poisoning and electricity are in common use throughout South and Southeast Asia, and may be expected to be a major threat to the ...
Tor sinensis, the Chinese or Red mahseer is a species of mahseer native to the Mekong River. [ 1 ] [ 2 ] It is known with certainty only from Yunnan , China ; reports from Cambodia, Laos, and Thailand require confirmation.
As all other mahseer species are omnivorous, it may be expected that Tor barakae is the same, with a diet that likely includes aquatic and terrestrial invertebrates, fruit and vegetation, small amphibians and other fish. It would seem probable that adult fish access headwaters for spawning during high water conditions.
