Schistura pervagata is a species of ray-finned fish, a stone loach, in the genus Schistura . The species occurs in Laos and Vietnam in streams with moderately fast to fast currents among riffles where there are substrates which vary from gravel to stone. [1]
Schistura fasciolata is a species of ray-finned fish in the stone loach genus Schistura found fast-flowing streams in China and Vietnam. It can each a length of 12 cm (4.7 in).
Schistura globiceps is a species of ray-finned fish in the genus Schistura. It has only been collected from a single stream in the upper Nam Tha watershed in Laos where it was found under stones in a fast flowing hill stream.
Schistura kohchangensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in moderately to fast flowing streams with gravel to stone substrates in eastern Thailand and Cambodia.
Schistura maepaiensis is a species of ray-finned fish, a stone loach in the genus Schistura. It has been recorded from the Salween basin in Mae Hong Son and Tak Provinces in north western Thailand and may also occur in Myanamar. Its habitat is riffles in streams with a gravel or stone bed and a moderate to fast current. It is occasionally found in the aquarium trade and its populations may be affected by any human activities which interrupt fast flowing water, such as logging or agriculture.
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 menanensis is a species of ray-finned fish, a stone loach in the genus Schistura. It has only been recorded the Mae Nam Nan drainage, a branch of the Chao Phraya in Thailand where it has been observed in streams with moderate to fast currents, in riffles, with gravel to stone beds. The specific name menanensis refers to the type locality of this species on the Mae Nam Nam.
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 nomi is a species of ray-finned fish, a stone loach, in the genus Schistura. This species is found in streams which have a moderate to fast current, in riffles, where the bed consists of gravel to stone in the Kong River in Laos. The specific name honours a Mr Nom who was the describer, Maurice Kottelat's, driver in Laos.
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 obeini is a species of ray-finned fish, a stone loach, in the genus Schistura. It has been recorded from the Nam Theun and Nam Gnouang rivers in Laos where it inhabits fast or very fast flowing water over pebble or stone beds in the headwaters of the rivers. The specific name honours François Obein of the Nam Theun 2 Electricity Consortium in Vientiane for the assistance he gave to the describer Maurice Kottelat in the field and for his organisation of logistics in the field.
Schistura paucicincta is a species of ray-finned fish, a stone loach, in the genus Schistura. It is only known from the Mae Nam Noi drainage, a tributary of the Salween River which forms the border between Thailand and Myanmar. This species inhabits streams with a moderate to fast current, in riffles, over beds varying from gravel to stone but it has also been recorded in small forest streams in very shallow water.
Schistura personata is a species of ray-finned fish, a stone loach, in the genus Schistura.It has only been recorded in the Nam San, a tributary of the Nam Ngum in the Mekong Basin of Laos where it can be found in moderately fast or fast flowing streams, among riffles, with a stone or gravel bed. Its population has been impacted by dams and by deforestation, agriculture and small scale gold mining and it is thought that it has declined.
Schistura pertica is a species of ray-finned fish, a stone loach, in the genus Schistura. It has only been recorded once, in 1997, from a very small stream entering the Nam Ou River, downstream of the Muang Khoa River in northern Laos, it is expected to occur elsewhere in the Nam Ou drainage. It was observed in streams with a moderate to fast current, in riffles, over beds varying from gravel to stone
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 punctifasciata is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found only in Laos where it is found only downstream of the subterranean section of the Xe Bangfai, inhabiting still water as well as moderately fast flowing streams over gravel substrates, with clear water.
Schistura russa is a species of ray-finned fish, a stone loach, in the genus Schistura. It is known from only two locations in the Nam Tha drainage system in Laos where it is found in streams with a moderate to fast flow in riffles with pebble or stone stream beds.
Schistura sexcauda is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in the basin of the Chao Phraya River in central Thailand where it has been recorded in streams with a moderate to fast current, in riffles, over substrates consisting of gravel to stone. Some authorities regard Schistura fowleriana as a synonym of this species.
Schistura similis is a species of ray-finned fish, a stone age, in the genus Schistura. It occurs in the Mae Nam Noi drainage, a tributary of the Salween which forms the border between Thailand and Myanmar. The species has only been recorded in Thailand but most likely occurs in Myanmar too. It has been recorded in streams with a moderate to fast current, in riffles, over substrates consisting of gravel to stone.
Schistura thanho is a species of ray-finned fish, a stone loach in the genus Schistura. It has only been recorded in the Vinh Thanh River drainage in Central Vietnam where it occurs in riffles with a very fast current. It is threatened by overfishing, the degradation and loss of habitat caused by dam constructions and deforestation resulting in the silting up of the streams it occurs in. The specific name is a reference to the “friendly people” of the Tha Nho ethnic community in Binh Dinh Province, Vietnam, where the type locality of this species is located.
Schistura waltoni is a species of ray-finned fish, a stone loach, in the genus Schistura. It is a species of in streams which have a moderate to fast current where it can be found in riffles, over gravel to rock beds. It is often recorded in small streams in forest, even where the water is very shallow. It occurs in the upper reaches the Chao Phraya watershed in Thailand in the rivers Mae Nam Ping, Mae Nam Wang and Mae Nam Yom. The specific name honours Joseph Walton a 19th Century contributor to the fish collection at the Academy of Natural Sciences of Philadelphia.
