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 term carp is a generic common name for numerous species of freshwater fish from the family Cyprinidae, a very large clade of ray-finned fish mostly native to Eurasia. While carp are prized quarries and are valued as both food and ornamental fish in many parts of the Old World, they are considered trash fish and invasive pests in many parts of Africa, Australia and most of the United States.
Balitoridae, the hillstream loaches or river loaches, is a family, of small fish from South, Southeast and East Asia. The family includes about 202 species. They are sometimes sold as "lizardfish" or "flossensaugers". Many of the species are popular for aquaria, species in the genus Sewellia are most commonly sold in the aquaria trade. They have a number of similarities with the Cobitidae, their sibling family of "loaches", such as multiple barbels around the mouth. They should not be confused with the loricariids, which look similar but are a family of catfish.
The pearl danio is a tropical fish belonging to the minnow family Cyprinidae. Originating in Sumatra, Myanmar, and Thailand and Vietnam ,this fish is sometimes found in aquariums by fish-keeping hobbyists. It grows to a maximum length of 2.6 inches (6.5 cm) and lives for around five years. The fish could have a brownish-yellow, pink, or a silver body and two light yellow/white or blue/red stripes. It has an iridescent look. The female fish has two pairs of barbels.
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. It is the widest waterfall in the world at 10,783 metres in width from one edge of its multiple channels to the other.
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 as a food source, and also on the 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". In Asian markets, names for basa include "Pacific dory" and "patin". 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.
Hemimyzon is a genus of freshwater ray-finned fish belonging to the family Balitoridae, the river or hillstream loaches. The species in this genus are found in eastern Asia.
Pangasius pangasius, the Pangas catfish, is a species of shark catfish native to fresh and brackish waters of Bangladesh, India, Myanmar, and Pakistan. It has also been introduced to Cambodia and Vietnam. This species grows to a standard length of 3 metres (9.8 ft). This species of fish is eaten by the people of South Asia, the other being P. silasi from the Krishna River.
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.
Anabarilius transmontanus is a species of cyprinid fish. It is known from the Red River and Pearl River drainages in Yunnan, China; it is expected to occur in northern Vietnam. It can grow to 16 cm (6.3 in) total length, although it is commonly around 10 cm (3.9 in) standard length. It occurs in both rivers and lakes. The species is threatened by domestic and urban water pollution, habitat loss, and possibly non-native species.
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.
Hemimyzon confluens is a species of ray-finned fish in the genus Hemimyzon. It is known from a single location in the Nam Ngum drainage in Laos, a tributary of the Mekong. The known material suggests a maximum standard length of about 47 mm (1.9 in). H. confluens is threatened by pollution from mining activities and hydro-power development.
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).
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.
