Schistura khamtanhi | |
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. [1] 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 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 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 bairdi is a species of ray-finned fish in the genus Schistura.
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 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 fusinotata is a species of ray-finned fish in the stone loach genus Schistura. This species has been recorded from stretches of the main Kong River and its tributaries in Laos where there are substrates consisting of stones and large gravel.
Schistura kloetzliae is a species of ray-finned fish, it is a stone loach in the most speciose genus in that family, Schistura. It has been recorded from the Mengla drainage in Yunnan and its tributary Nam Youan in Luang Namtha province in Laos. It occurs in medium fast currents in streams with gravel or stony bottoms. The specific name honours Antoinette Kottelat-Kloetzli, for her help and support of Maurice Kottelat during his work in Laos, among other things.
Schistura kongphengi is a species of ray-finned fish, a stone loach, in the genus Schistura, the most specious of the genera of stone loaches. It occurs in the middle and upper parts of the Nam Gnouang drainage south to the drainage of the Xe Bang Hiang in Laos and Vietnam. It has been recorded from dstreams with moderate to fast currents over substrates of gravel and sands and among riffles and rapids. The specific name honours Kongpheng Bouakhamvongsa, an official with the Department of Livestock and Veterinary of the Ministry of Agriculture of the Lao People's Democratic Republic, for the help he gave to Maurice Kottelat with his field work in Laos.
Schistura leukensis is a species of ray-finned fish, a stone loach in the genus Schistura. It has only been recorded from a single river, a tributary of the Mekong in Laos. This river has been affected by damming upstream of this species' main habitat and it is unknown how this has impacted the population. Other human activities such as deforestation, agriculture, siltation and pollution may have also had effects on 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 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 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 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".

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 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).
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.
