Dzihunia is a genus of stone loaches native to Central Asia.
There are currently four recognized species in this genus: [1]
On the other hand, in a recent molecular study on DNA barcoding in fish from Uzbekistan, it was found that the species diversity of Dzihunia is more than three, as previously believed. [3]
Cobitidae, also known as the true loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families. The family includes about 260 described species. New species are being described regularly.
The spined loach is a common freshwater fish in Europe. It is sometimes known as spotted weather loach, not to be confused with the "typical" weather loaches of the genus Misgurnus. This is the type species of the spiny loach genus (Cobitis) and the true loach family (Cobitidae).
Cobitis dalmatina is a species of ray-finned fish in the true loach family (Cobitidae). It is endemic to Croatia. This fish was long believed to be part of the widespread spined loach.
Cobitis narentana is a species of ray-finned fish in the true loach family (Cobitidae). It is found in Bosnia and Herzegovina and Croatia. This fish was long believed to be part of the widespread spined loach.
Cobitis ohridana is a species of ray-finned fish in the true loach family (Cobitidae). It is only found in Albania, Montenegro, Serbia, North Macedonia, and Greece. This fish was long believed to be part of the widespread spined loach.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. They can be distinguished from other genera of Nemacheilidae by marked sexual dimorphism, including the development of nuptial tubercles on breeding males. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
Pseudoscaphirhynchus is a genus of relatively small, highly threatened sturgeons that are restricted to the Aral Sea system, including the Amu Darya and Syr Darya river basins, in Central Asia.
Rhyacoschistura suber is a species of ray-finned fish, a stone loach, in the genus Rhyacoschistura. This species was originally described from three specimens collected among leaf litter in very shallow water in a small forest creek in the Nam Leuk drainage basin in Laos in 1997. These specimens were revealed to be juveniles and the species was re-described in 2019 on the basis of adult specimens. Based on the re-description, the species was moved from Schistura to the newly described genus, Rhyacoschistura.
DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections, an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode to identify an item in its stock against its reference database. These "barcodes" are sometimes used in an effort to identify unknown species or parts of an organism, simply to catalog as many taxa as possible, or to compare with traditional taxonomy in an effort to determine species boundaries.
Loaches are ray-finned fish of the suborder Cobitoidei. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidei comprise about 107 genera divided among 9 families.
Oxynoemacheilus is a genus of fish in the family Nemacheilidae found in Europe and Western Asia.
The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, Afronemacheilus found in Africa. The family includes about 790 species.
Alburnoides holciki is a species of small freshwater fish in the family Cyprinidae. It was endemic to the Hari River drainage in northwestern Afghanistan, northeastern Iran, and southern Turkmenistan. Recent studies have shown that this species is also found in the Amu Darya basin in Tajikistan and Uzbekistan.
Gobio sibiricus is a species of gudgeon, a small freshwater in the family Cyprinidae. It was endemic to Mongolia, where it is found in Ob, Yenisei and Nura drainages. A recent study has shown that this species is also found in the upper reaches of the Amu Darya in Uzbekistan.
Linopodes is a cosmopolitan genus of mites in the family Cocceupodidae. There are at least two described species.
DNA barcoding methods for fish are used to identify groups of fish based on DNA sequences within selected regions of a genome. These methods can be used to study fish, as genetic material, in the form of environmental DNA (eDNA) or cells, is freely diffused in the water. This allows researchers to identify which species are present in a body of water by collecting a water sample, extracting DNA from the sample and isolating DNA sequences that are specific for the species of interest. Barcoding methods can also be used for biomonitoring and food safety validation, animal diet assessment, assessment of food webs and species distribution, and for detection of invasive species.
Triplophysa ferganaensis, known as the Fergana stone loach, is a species of ray-finned fish in the family Nemacheilidae. It is endemic to the Shohimardonsoy stream in Fergana Valley, Uzbekistan. It lives in fast-flowing rivers over 1500m in altitude.
Triplophysa wulongensis is a species of ray-finned fish in the genus Triplophysa endemic to a single subterranean pool in Furong Cave, Wulong County, Chongqing, China.
Triplophysa daryoae, the Sokh stone loach, is a species of ray-finned fish in the family Nemacheilidae. It is endemic to the Sokh River in Fergana Valley, Uzbekistan. It lives in fast-flowing rivers over 1050m in altitude.
Dzihunia pseudoamudarjensis, the Uzbekistan stone loach, is a species of ray-finned fish in the family Nemacheilidae. It is endemic to the Fergana Valley, Uzbekistan. It lives in slowly flowing, turbid water of the Great Fergana Canal.
