Schistura is a genus of fish in the stone loach family Nemacheilidae native to the streams and rivers of the southern and eastern Asia. Some of these species are troglobitic.
Schistura alticrista is a species of ray-finned fish in the genus Schistura. This stone loach has only been recorded in the basin of the Nam Mae Yuam, a tributary of the Salween River in Mae Hong Son Province, north west Thailand. It has been reported that this species has been recorded in the Salween mainstream near the inflow of the Nam Mae Yuam. The habitat from which the species has been collected is small streams over a substrate of pebbles. This fish is harvested by subsistence fisheries. Species in the genus Schistura are omnivores although the majority of their diet is animal matter such as zooplankton, insects, worms and crustaceans with small amounts of plant material and detritus. S. alticrista is occasionally traded in the aquarium trade.
Schistura amplizona is a species of ray-finned fish in the stone loach genus Schistura. It been recorded from only two river basins, the Nam Tha and Nam Youan, in northern Laos, of these the Nam Youam flows to Xishuangbanna in Yunnan, China and specimens of this species have been collected very close to the border so this species may occur in Yunnan. Its preferred habitat appears to be streams with a moderate flow and a bed of rock or pebbles. This species is harvested by local subsistence fisheries but the main potential threats are alteration of natural water courses through deforestation and agriculture.
Schistura aramis is a species of ray-finned fish in the stone loach genus Schistura from the Nam Nua catchment, a tributary of the Nam Ou in Laos, it may also possibly occur in Vietnam. The specific name comes from one of Alexandre Dumas' The Three Musketeers, Aramis as do that of two other Schistura species endemic to the Nam Ou basin, S. athos and S.porthos.
Schistura athos is a species of ray-finned fish in the stone loach genus Schistura, its specific name athos is from, Athos, one of the Three Musketeers by Alexandre Dumas, as do that of two other Schistura species endemic to the Nam Ou basin, S. aramis and S.porthos. It has only been recorded from the Nam Ou basin in Laos, as well as from a stretch of the Nam Noua, a tributary of the Nam Ou, in Vietnam. S. athos has been collected from rapids and stretches of the main river with stone substrates.
Schistura atra is a species of ray-finned fish in the stone loach genus Schistura. This species has only been recorded from the drainage systems of the Nam Theun and Nam Gnouang, tributaries of the Mekong, in Laos. It can be found in the parts of streams with deep water and fast currents where it lives among the rocks. The lower parts of the basins it occurs in have been impacted by damming and this species has probably been extirpated from these area but it continues to survive upstream of the reservoirs. The habitat of this fish is affected by deforestation, agriculture and gold mining as well as the dams.
Schistura beavani, the creek loach, is a species of ray-finned fish in the stone loach genus Schistura. It is a widely distributed species, especially in the Ganges where it can be found in the Indian states of Meghalaya, Uttaranchal, Uttar Pradesh and West Bengal and Nepal, it has also been reported from Bangladesh and its presence in Meghalaya need to be confirmed. Adults are found in fast flowing, clear streams with a pebbly substrate.
Schistura cataracta is a species of ray-finned fish in the stone loach genus Schistura. It occurs in the Nam Theun and Nam Gnouang, in the Mekong basin of Laos. It prefers stretches of rivers with fast current and a stony or rocky substrate, but it does occasionally occur over gravel or sandy substrates. It can also be found in reservoirs, albeit at low densities and dams are the biggest threat to this species.
Schistura chapaensis is a species of ray-finned fish in the stone loach genus Schistura from north western Vietnam.
Schistura cincticauda is a species of ray-finned fish in the stone loach genus Schistura. It has been recorded from a tributary of the Salween River in Thailand, Myanmar and Laos.
Schistura coruscans is a species of ray-finned fish in the stone loach genus Schistura from the Nam San drainage, a tributary of the Nam Ngum in Laos.
Schistura crabro is a species of ray-finned fish in the stone loach genus Schistura from Laos.
Schistura daubentoni is a species of ray-finned fish in the stone loach genus Schistura. Iyt is found in the middle Mekong drainage in central Laos and northern Cambodia, including the Tonlé San and lower Kong River and it is considered that it is probably found in the reaches of the Mekong between these areas and in eastern Thailand. The specific name honours François d’Aubenton a zoologist at the Muséum National d’Histoire naturelle in Paris, who collected type specimen in 1964.
Schistura defectiva is a species of ray-finned fish in the stone loach genus Schistura from Laos.
Schistura desmotes is a species of ray-finned fish in the stone loach genus Schistura. It is found in Ratchaburi Province of Thailand where it inhabits streams with a moderate current and a gravel or stone substrate. The specific name desmotes mean "prisoner" and refers to the 7–9 broad dark-brown transverse bands on the fish's body, which reminded Fowler of a striped prisoner's uniform.
Schistura incerta is a species of ray-finned fish in the stone loach genus Schistura. It occurs in the Pearl River basin and Han Jiang in southeast China and northern Vietnam.
Schistura irregularis is a species of ray-finned fish in the stone loach genus Schistura, it is found in Laos.
Schistura isostigma is a species of ray-finned fish in the stone loach genus Schistura. It occurs in streams with in moderate to fast currents, with sand and gravel beds in the Mekong basin in Laos, it should also occur in Cambodia and Thailand.
Schistura poculi is a species of ray-finned fish, a stone loach, in the genus Schistura. This species of stone loach is currently thought to occur in the basins of the Mekong, Salween and Chao Praya rivers in Myanmar, Thailand and Laos. However, these may refer to more than one species, in which case the name S. poculi belongs to the population in the Chao Praya. It can be found in streams with moderately fast to fast currents among riffles where there are substrates which vary from gravel to stone. The specific name poculi means "bowl" and refers to the type locality, Doi Angkon in Thailand with angkon meaning "crow's bowl".
Schistura quasimodo is a species of stone loach in the genus Schistura. It is known from a single stream from the Nam Ngum drainage in Laos, a tributary of the Mekong. It has a cylindrical body, sometimes with a conspicuous hump. The known material suggests a maximum standard length of about 48 mm (1.9 in).
