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 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 breviceps is a species of ray-finned fish in the stone loach genus Schistura. It has only been recorded in the drainage system of the Mae Nam Kok, a tributary of the Mekong in northern Thailand and Myanmar. It has been seen in streams with a moderate flow over gravel or stone stream beds.

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 dorsizona is a species of ray-finned fish in the stone loach genus Schistura. It is known to occur in the Mekong basin in Laos and Cambodia, it is expected that it occurs in eastern Thailand too.

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 khamtanhi is a species of ray-finned fish in the genus most speciose genus in the stone loach family, Schistura. It is found in the Kong River basin in Laos and in the main Mekong river in Cambodia and Laos where it is abundant, being an important quarry species for the fish traps at Kohne Falls. It inhabits rapids and Sony bottomed stretches of the main Mekong and its tributaries and it migrates past the Kohne Falls in January and February annually. It is the only member of the genus Schistura which is known to be migratory. The specific name honours Khamtanh Vatthanatham, a Fisheries Programme Officer of the Mekong River Commission who was very helpful to the Maurice Kottelat during his 1999 survey, in which this species was discovered.

Schistura kontumensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It has only been recorded a few times from large rivers and streams in the headwaters of the Sesan River which is a tributary of the Sekong River, which is a tributary of the Mekong, in Kontum Province, Vietnam. When sampled., however, it was found to be common and hardy, tolerating water which had flown through urban areas and which had been polluted with water used for washing. Iys population trends are unknown and despite its hardiness it may have been affected by dams.

Schistura macrotaenia is a species of ray-finned fish, a stone loach, in the genus Schistura. It occurs in the Tengtiao Jiang River drainage in Yunnan and may also occur in the same river drainage in northern Vietnam.

Schistura magnifluvis is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in the middle Mekong basin in Thailand and Laos, from the Nam Heung basin to the Xe Don system, it probably occurs in Cambodia too. It is found in streams and rivers, including the nmain channel of the Mekong, in stretches of moderate to fast current over a variety of substrates from mud to stone.

Schistura melarancia is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in the Mekong drainage in Laos and Vietnam. The specific name melarancia is derived from an old Italian word for an orange and refers to the orange-brown colour of the fins and body of this species.

Schistura nicholsi is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in the Mekong basin of north eastern Thailand, Laos and it is also likely to be found in Cambodia. It occurs in shallow riffles with moderate to fast flows. Human modification of the rivers' morphology through such activities as logging and agriculture are affecting this species range. However, its distribution covers a wide geographic range and it is assessed as Least Concern by the IUCN. The specific name honors John Treadwell Nichols (1883-1958) who was curator of fishes at the American Museum of Natural History and who made an important contribution to the ichthyology of China, and especially to the knowledge of loaches.

Schistura nudidorsum is a species of ray-finned fish, a stone loach, in the genus Schistura. This species has only been recorded from the drainage basins of the Nam Theun and Nam Gnouang, tributaries of the Mekong in Laos. It occurs in streams with a moderate to fast current and a substrate which varies from gravel to stone, in riffles. It is threatened by the construction of dams, as well as logging, deforestation, agriculture and gold mining.

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 porthos is a species of ray-finned fish in the stone loach genus Schistura from the Mekong basin; the Nam Ngiap, Nam Khan, Nam Xuang, Nam Ou and Nam Tha drainages in northern Laos and the Luosuojiang drainage in Xishuangbanna, Yunnan. 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.aramis.

Schistura prashadi is a species of ray-finned fish, a stone loach, in the genus Schistura.

Schistura sombooni is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found only in the Mekong drainage system in Laos where it occurs in stretches of streams with a relatively slow current and a gravel or sandy stream bed. The specific name honours Somboon Phetphommasouk a liaison engineer with the Nam Theun 2 Electricity Consortium of Vientiane who rendered assistance and help in the field to the describer of this species, Maurice Kottelat.
