Triplophysa is a large genus of stone loaches,[1][2][3] most of which are found in and around the Qinghai-Tibet Plateau (China).[4]

Currently Triplophysa is a mixed assemblage of species. Some lineages have been identified and treated as subgenera (Hedinichthys, Qinghaichthys, Labiatophysa, Indotriplophysa, and Tarimichthys),[1] but following Kottelat (2012)[1] and the Catalog of Fishes[3] are treated as genera in Wikipedia. FishBase, however, includes these in Triplophysa.[2]

Ecology

Triplophysa zhaoi holds the record for the lowest altitude for Asian fish: it is found at 50 m (160 ft) below sea level in swamps of the Lükqün oasis, in the Turpan depression, Xinjiang. In the other end, Triplophysa stoliczkae holds the record altitude for Asian fish: it is found at 5,200 m (17,100 ft) above sea level in hot springs near the Longmu Lake in western Tibet.[1] Triplophysa dalaica has been used as model species to study adaptation to high-altitude hypoxia, and 13 positively selected genes involved in hypoxia response have been identified.[5] Some species are blind troglobites.[4][6]

Species

There are currently 125 recognized species in this genus:[1]
