Hemimyzon ecdyonuroides is a species of hillstream loach (a ray-finned fish) in the genus Hemimyzon . It is known from two tributaries of the Mekong, from Sekong River and Sesan River drainages in Vietnam and Laos.
The Khone Falls and Pha Pheng Falls together form a waterfall located in Champasak Province on the Mekong River in southern Laos, near the border with Cambodia. At 35,376 feet (10,783 m) wide, it is the widest waterfall in the world.
Nam Ngum is a 354 km long river in Laos. It is a major tributary of the Mekong River.
Basa is a species of catfish in the family Pangasiidae. Basa are native to the Mekong and Chao Phraya basins in Mainland Southeast Asia. These fish are important food fish with an international market. They are often labelled in North America and Australia as "basa fish", "swai", or "bocourti". In the UK all species of Pangasius may legally be described as "river cobbler", "cobbler", "basa", "pangasius", "panga", or any of these with the addition of "catfish". In the rest of Europe, these fish are commonly marketed as "pangasius" or "panga". Other related shark catfish may occasionally be incorrectly labeled as basa fish, including P. hypophthalmus and P. pangasius.
The giant barb, Siamese giant carp, or simply Siamese carp, is the largest species of cyprinid in the world. These migratory fish are found only in the Mae Klong, Mekong, and Chao Phraya River basins in Indochina. Populations have declined drastically due to habitat loss and overfishing, and the giant barb is now considered critically endangered.
Hemimyzon taitungensis is a species of ray-finned fish in the family Balitoridae that is endemic to Taiwan. It is a small freshwater fish currently known only from running waters of the Central Mountain Range of Taiwan at high and middle elevations. In contrast to H. formosanus, it appears to be a well-defined species with no signs of strong genetic structuring suggestive of cryptic species.
Bagarius rutilus is a species of sisorid catfish native to Laos, Vietnam and Yunnan in China where it is found in the Nam Sam, Nam Ma and Red River basins. This species grows to a length of 100 centimetres (39 in) SL.
Garra imberba is a species of ray-finned fish in the genus Garra from Yangtze, upper Mekong and Red River basins in China and Vietnam.
Poropuntius huangchuchieni is a species of ray-finned fish in the genus Poropuntius which is found in the upper Mekong River basin and the Red River basin in the Yunnan. It may also occur in these rivers in Laos and northern Vietnam.
Poropuntius krempfi is a species of ray-finned fish in the genus Poropuntius from the Red River drainage in Vietnam and Yunnan, and from the Ma River drainage in Vietnam and Laos.
The Mongolian redfin is a species of ray-finned fish in the genus Chanodichthys. This East Asian freshwater cyprinid is found in China, Russia and Mongolia where it ranges from the Amur River south to the Yangtze and inland to Lake Buir and Kherlen River. There are also records from the Red River in Vietnam that probably are this species. It reaches 1 m in length and 4 kg (8.8 lb) in weight.
Schistura carbonaria is a species of ray-finned fish in the stone loach genus Schistura. It is found in central Vietnam in some coastal drainage systems, from the Ve River to the Qang Tri River, and the River Xe Kong, in the Xe Kong its range may extend into Laos. It can be found in medium-sized rivers and streams which have a strong current over a substrate of rocks and gravel.
Beaufortia leveretti is a species of ray-finned fish in the genus Beaufortia.
Hemimyzon formosanus is a species of hillstream loach in the genus Hemimyzon. It is endemic to western portion of Central Mountain Range of Taiwan. Its maximum length is 10 cm (3.9 in). Variations in nucleotide sequences within the mitochondrial control region show strong geographic structuring suggestive of a cryptic species complex.
Hemimyzon khonensis is a species of hillstream loach in the genus Hemimyzon. It is known from a single specimen collected in the Mekong at the Khone Falls in Laos, near the Cambodian border; it is named for the falls. The specimen was 51 mm (2.0 in) in standard length.
Hemimyzon macroptera is a species of hillstream loach in the genus Hemimyzon. It is found in clear-water streams with rocky bottom in the Nanpan River basin, Yunnan, China. It is naturally scarce but widespread.
Hemimyzon sheni is a species of ray-finned fish in the genus Hemimyzon. It is only known from Tar-Ju River basin, Taitung County, southeast Taiwan, where its type locality is. Only three specimens were collected and later attempts to find more specimens have failed. Among its relatives, H. sheni most closely resembles H. formosanus, but it seems to be more a head-water species than H. formosanus. It is a small species with standard length of 5 cm (2.0 in).
Hemimyzon elongata is a species of ray-finned fish in the genus Hemimyzon. It has been found in the Mekong basin in Yunnan, China. It is a benthopelagic, freshwater fish.
Hemimyzon tchangi is a species of ray-finned fish in the genus Hemimyzon.
Abbottina binhi is a species of ray-finned fish in the genus Abbottina. It is endemic to the Bằng River in Cao Bằng Province, Vietnam. It is only known from its type series.
Hemiculter krempfi is a species of ray-finned fish in the genus Hemiculter. It is known only from the Cai River in Khanh Hoa Province and the Da Rang River in Phu Yen Province of central Vietnam. Here it is found mainly over sand substrates and is infrequently encountered in fish markets.
