Schistura macrocephalus | |
Schistura macrocephalus is a species of ray-finned fish. a stone loach, in the genus Schistura . It occurs in riffles over stony or gravel beds in streams with moderate to fast currents in the Mengla River in Yunnan, a tributary of the Mekong, and the Nam Youan in northern Laos, in turn a tributary of the Mengla.

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 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 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 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 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 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 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 moeiensis is a species of ray-finned fish, a stone loach, in the genus Schistura. It is found in the Mae Nam Noi drainage system, a tributary of the Salween, the Mae Nam Noi forms the border between Thailand and Myanmar. It has been recorded from streams which have a moderate to fast current, in riffles, over beds consisting of gravel to stone.
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 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 procera is a species of ray-finned fish, a stone loach, in the genus Schistura. It has a wide distribution in the Nam Ou drainage, a tributary of the Mekong in Laos where it occurs in a variety of flowing water habitats from forest streams to waterfalls.
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 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 tizardi is a species of ray-finned fish, a stone loach, in the genus Schistura from the Kong River basin in southern Laos. It was found in rapids and stretches of river with stone bottoms, in both the mainstream and the tributaries.
