Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China. [1] Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera ( Hedinichthys , Indotriplophysa , Labiatophysa , Qinghaichthys and Tarimichthys ), but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms. [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 in Xinjiang. In the other end, Triplophysa stolickai 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. [3] 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. [4] Some species are blind cave-dwellers. [1] [5]

<i>Acrossocheilus</i> Genus of fishes

Acrossocheilus is a genus of ray-finned fishes in the family Cyprinidae, native to freshwater in China, Taiwan, Laos, and Vietnam. They are fairly small, no more than 30 cm (1 ft) in standard length.

<i>Schizothorax</i> Genus of fishes

Schizothorax is a genus of cyprinid fish found in southern and western China, through northern South Asia (Himalaya) and Central Asia, to Iran, with a single species, S. prophylax, in Turkey. They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin. Their scientific name means "cloven-breast", from Ancient Greek schízeïn (σχίζειν) 'to cleave' and thórax (θώραξ) 'breast-plate'. The western species are typically referred to as marinkas from their Russian name marinka (маринка), while the eastern species are usually called snowtrout. Although they do resemble trouts in habitus this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.

Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae endemic to China, where only found in Guangxi, Guizhou and Yunnan. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.
