Schistura leukensis | |
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. [1]
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 antennata is a species of ray-finned fish in the stone loach genus Schistura. It is found in very small, steep streams in forested mountains with rocky substrates and waterfalls, although it avoids riffles and waterfalls and is restricted to reaches with a moderate flow. It has only been recorded from the headwaters of the River Lam drainage in Ha Tinh Province in central Vietnam.
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 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.
Schistura bairdi is a species of ray-finned fish in the genus Schistura.
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 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 denisoni is a species of ray-finned fish in the stone loach genus Schistura described from the Bhavani river of Tamil Nadu.
Schistura huongensis is a species of ray-finned fish in the most speciose genus of the stone loach family Nemacheilidae, Schistura. It has been recorded from the drainage basins of the Perfume River and Cam Lo in central Vietnam. It can be found in the slack water upstream of riffles in medium-sized mountain rivers and streams with a fast current.
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 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 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 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 susannae is a species of ray-finned fish, a stone loach, in the genus Schistura. It occurs in small mountain streams which have waterfalls and small riffles, where it is usually observed in pools with gravel or sandy bottoms. It has only been found to occur in the Mong Mo river, a small coastal drainage, in central Vietnam. The specific name honors Susanne Klähr, for the help she gave to Maurice Kottelat in his field work.
Schistura kodaguensis is a species of ray-finned fish, a stone loach, in the genus Schistura. This species has been recorded from a single stream with a swift current and gravel bottom in the Cauvery River system in Karnataka, India. The specific name is derived from Kodagu District where the type specimen was collected.
Schistura sikmaiensis is a species of ray-finned fish, a stone loach in the genus Schistura. It is a benthic species which is found in cool, fast flowing streams with gravelly beds. It is found in the Irrawaddy River in Yunnan, Manipur and in Myanmar, it has been reported in Bangladesh and elsewhere in India.
