Schistura bachmaensis is a species of ray-finned fish in the stone loach genus Schistura . It has been only been recorded in a single small stream with fast running water and boulders in Thua Thien Province of Vietnam. [1]
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 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 amplizona is a species of ray-finned fish in the stone loach genus Schistura. It been recorded from only two river basins, the Nam Tha and Nam Youan, in northern Laos, of these the Nam Youam flows to Xishuangbanna in Yunnan, China and specimens of this species have been collected very close to the border so this species may occur in Yunnan. Its preferred habitat appears to be streams with a moderate flow and a bed of rock or pebbles. This species is harvested by local subsistence fisheries but the main potential threats are alteration of natural water courses through deforestation and agriculture.
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 balteata is a species of ray-finned fish in the stone loach genus Schistura. It found in hill streams draining from the Myinmoletkat Taung mountain in Tenasserim in southern Myanmar, and has now been recorded in western Thailand too. It is kept in the aquarium trade where it is often referred to as the sumo loach, the specific name derives from the Latin balteatus, which means baldric or shoulder strap, referring to the colour pattern this species.
Schistura beavani, the creek loach, is a species of ray-finned fish in the stone loach genus Schistura. It is a widely distributed species, especially in the Ganges where it can be found in the Indian states of Meghalaya, Uttaranchal, Uttar Pradesh and West Bengal and Nepal, it has also been reported from Bangladesh and its presence in Meghalaya need to be confirmed. Adults are found in fast flowing, clear streams with a pebbly substrate.
Schistura bolavenensis is a species of ray-finned fish in the stone leach genus Schistura. It is found in the Bolaven Plateau in Laos where it occurs in clear rocky streams at altitudes of 800–1,200 m which form tributaries of the Xe Kong and Xe Don rivers were it feeds on insects. It is threatened by proposals to construct dams and from the mining of bauxite on the Bolovan Plateau.
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 chindwinica is a species of ray-finned fish in the stone loach genus Schistura. This species has been recorded from only two streams in the drainage of the Brahmaputra in Manipur. The species is threatened by siltation caused by slash and burn agriculture and the proposed building of a dam with will flood some of the waterways it occurs in.
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 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 denisoni is a species of ray-finned fish in the stone loach genus Schistura described from the Bhavani river of Tamil Nadu.
Schistura kaysonei, the Laotian cave loach, is a species of ray-finned fish in the genus Schistura. It is endemic to Laos where only found in streams in caves. Like other cave-adapted fish, it is blind and has little pigmentation. This troglobitic species has been recorded from only a single cave in a karst landscape in Khammouane Province in Laos. Here it can be found around 100m from the cave entrance and its diet is thought to be organic detritus, such as bat guano, and micro-organisms. It is threatened by a decline in the quality and quantity of the water flowing through the case, caused by deforestation and increased agriculture, as well as potential overfishing for the aquarium trade. The specific name honours Kaysone Phomvihane (1920-1992), who was president of 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 nasifilis is a species of ray-finned fish, a stone loach, in the genus Schistura. This species was described from two rivers in Vietnam but has not been recorded since it was first described, although it was looked for in 2000 and 2002.
Schistura spekuli is a species of ray-finned fish, a troglobitic stone loach, in the genus Schistura. It has been recorded from a single cave in central Vietnam. The specific name refers to SPEKUL, the speleological club of the University of Leuven in Belgium.
Schistura tenura is a species of ray-finned fish, a stone loach, in the genus Schistura. This species has only ever been recorded from the Nam Leuk catchment in Laos. It was recorded in a small stream with a bed of rock and stone, it has not been recorded since 1998 but there have been no searches for it.
