Schistura yersini | |
Schistura yersini is a species of ray-finned fish, a stone loach, in the genus Schistura which is found in two mountain rivers near Dalat in Vietnam. The species is abundant in steep, streams and rivers which have a gravel or rocky substrate and fast current. It is resistant to organic pollution and human disturbance of its habitat and is able to persist in streams flowing through settlements. It is most common in riffles and rapids where the water flow is greater than 1 metre per second below the surface. [1] The specific name honours the Swiss biologist and humanist Alexandre Yersin (1863-1943), who spent a great deal of his life working around Dalat near where the original type of this species was collected.

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 deansmarti is a species of ray-finned fish in the stone loach genus Schistura. It is found in cave streams in a karst landscape in the Thung Salaeng Luang National Park of Phitsanulok Province where it lives mainly on the stream beds and feeds on organic material and micro-organisms. The specific name honors the British speleologist who collected the original specimens and who works for the conservation of caves in Thailand.
Schistura hingi is a species of ray-finned fish in the most speciose genus of stone loaches, Schistura. It occurs in the Pearl River basin of southeastern China and the coastal drainages in central Vietnam, it probably also occurs in the costal drainages of northern Vietnam too where it inhabits medium-sized rivers and streams where a substrate of rocks and gravel lies in riffles. The specific name honours a specimen collector, Ah Hing, whose efficiency in collecting for the botanist-ornithologist Geoffrey Herklots of Hong Kong University, Hing's patience and skill enabled Herre "to get many specimens”.
Schistura nagaensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It is a benthic species which is found in hill streams with a fast currents over a gravel substrate. It occurs in the Tizu River in the Chindwin basin of Manipur and Nagaland, it may also occur in the Tizu River in Myanmar. Slash and burn cultivation within the drainage of the Tizu has contributed to a decline in quality of hill stream habitats and resultant threats to fish populations which are also threatened by destructive fishing techniques including the use of explosives and poisons.
Schistura namboensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It normally occurs in the rapids and riffles of medium-sized rivers and streams but it can also be found in reaches with a slow current and sandy substrate. This species appears to have some resistance to organic pollution and occurs in streams flowing through settlements, and is often the last fish species to remain in such streams. It is found in the coastal drainages in southern and central Vietnam and also in Laos in some rivers which rise there before flowing into Vietnam.
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 papulifera is a critically endangered species of ray-finned fish, a troblobitic stone loach, in the genus Schistura endemic to the state of Meghalaya in India. It is currently known to be restricted to the Krem Synrang Pamiang cave system near the Jaintia Hills, where it is threatened by limestone extraction. This species lives in pools of standing water within the cave system preferring these to the streams of flowing water, being most numerous in the largest and deepest pools. This may be because the larger pools offer a more stable environment for the fish. The specific name is a compound of the Latin papula meaning "a small tumour" and fera meaning "to bear", referring to the growths around the lower half this species head.
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 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 stone loach in the genus Schistura. This species 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 psittacula is a species of ray-finned fish, a stone loach in the genus Schistura. It is found in two rivers in central Vietnam where it inhabits riffles in medium-sized mountain rivers and streams in riffles which have a swift current over gravel beds. It feeds on aquatic invertebrates.
Schistura rupecula is a species of ray-finned fish, a stone loach, in the genus Schistura. It is distributed through the eastern Himalayas from North Bengal through Bihar, Himachal Pradesh, Uttaranchal and Uttar Pradesh in India and into Nepal. Its habitat is hill streams with pebbly stream beds while adults are often found in shallow water riffles and spring pools. The specific name rupecula means "rock dweller" which was given to the species by its describer John McClelland in reference to the hill streams around Simla from where the type specimens were collected. It is the type species of the genus Schistura.
Schistura sertata is a species of ray-finned fish, a stone loach, in the genus Schistura. It is only found in the Nam Xi, a small stream near Luang Prabang in Laos, where it was found between tree roots and among leaf litter within the stream.

It is known to be raised in local subsistence fisheries and traded both nationally and internationally as an ornamental fish.
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 honors Susanne Klähr, for the help she gave to Maurice Kottelat in his field work.
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.
