Schizothorax heterochilus is a species of ray-finned fish in the genus Schizothorax from the upper parts of the Yangtze basin in China. [3]
Yangtze or Yangzi is the longest river in Eurasia and the third-longest in the world. It rises at Jari Hill in the Tanggula Mountains of the Tibetan Plateau and flows 6,300 km (3,915 mi) in a generally easterly direction to the East China Sea. It is the fifth-largest primary river by discharge volume in the world. Its drainage basin comprises one-fifth of the land area of China, and is home to nearly one-third of the country's population.
The Chinese paddlefish, also known as the Chinese swordfish, is an extinct species of fish that was formerly native to the Yangtze and Yellow River basins in China. With records of specimens over three metres and possibly 7 m (23 ft) in length, it was one of the largest species of freshwater fish. It was the only species in the genus Psephurus and one of two recent species of paddlefish (Polyodontidae), the other being the American paddlefish. It was an anadromous species, meaning that it spent part of its adult life at sea, while migrating upriver to spawn.
Dian Lake, also known as Dianchi, Dianchi Lake, Lake Dian and Kunming Lake, is a fault lake located on the Puduhe-Xishan fault in Kunming, Yunnan, China at 24°23′–26°22′ N, 102°10′–103°40′ E. Its nickname is the "Sparkling Pearl Embedded in a Highland". It is the model for the Kunming Lake in Beijing's Summer Palace. Its name is the source of Yunnan's Chinese abbreviation 滇.
Schizothorax is a genus of cyprinid fish found in southern and western China, through northern South Asia (Himalaya) and Central Asia, to Iran, with a single species, S. prophylax, in Turkey. They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin. Their scientific name means "cloven-breast", from Ancient Greek schízeïn (σχίζειν) 'to cleave' and thórax (θώραξ) 'breast-plate'. The western species are typically referred to as marinkas from their Russian name marinka (маринка), while the eastern species are usually called snowtrout. Although they do resemble trouts in habitus this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.
Dabry's sturgeon, also known as the Yangtze sturgeon, Changjiang sturgeon and river sturgeon, is a species of fish in the sturgeon family, Acipenseridae. It is endemic to China and today restricted to the Yangtze River basin, but was also recorded from the Yellow River basin in the past. It was a food fish of commercial importance. Its populations declined drastically, and since 1988, it was designated an endangered species on the Chinese Red List in Category I and commercial harvest was banned. It has been officially declared extinct in the wild by the IUCN as of July 21, 2022.
Anabarilius liui is a species of ray-finned fish in the genus Anabarilius. The nominate subspecies liui is endemic to the upper Yangtze basin in China, but there are no recent records and it is considered extinct in the 2009 Chinese red list.
The Balkhash marinka, is a species of ray-finned fish in the genus Schizothorax of the family Cyprinidae which is found in the Lake Balkhash basins in Kazakhstan and Xinjiang. It uses gravel substrates for spawning and the unshed roe is toxic.
Schizothorax chongi is a species of ray-finned fish in the genus Schizothorax from the upper parts of the Yangtze basin in China.
Schizothorax cryptolepis is a species of cyprinid fish in the genus Schizothorax from the upper parts of the Yangtze basin in China.
Schizothorax dolichonema is a species of ray-finned fish in the genus Schizothorax from the upper parts of the Yangtze basin in China.
Schizothorax grahami, the Kunming snowtrout, is a species of ray-finned fish in the genus Schizothorax. It is endemic to Lake Dianchi, its tributaries and connected springs, in Yunnan Province, China. The species has not been caught in the lake in the past 20 years, but it is present in one tributary drainage basin. The introduction of exotic fish is the main threat to this species.
Schizothorax griseus is a species of ray-finned fish in the genus Schizothorax. It is found in the basins of the Yangtze River basin, the upper Pearl River and the upper Mekong River in southern China.
The Kumaon snowtrout is a species of ray-finned fish in the genus Schizothorax.
Schizothorax lantsangensis is a species of ray-finned fish in the genus Schizothorax which is endemic to the upper Mekong River basin in Yunnan.
Schizothorax oligolepis is a species of ray-finned fish in the genus Schizothorax. This specie sis found in the upper Irrawaddy River basin in Yunnan and the Putao District in Myanmar.
Schizothorax plagiostomus is a species of ray-finned fish in the genus Schizothorax. Schizothorax plagiostomus locally known as khont', snow trout, snow carp, snow barbel and swati fish has an elongated sub cylindrical body with short, blunt and slightly prognathous upper jaw. Ventral surface of head and anterior part of body flattish, short, somewhat cone shaped and blunt. Snout usually smooth covered with warys in male. Interorbital space broad and flat. Mouth inferior, wide and slightly arched; lips fleshy and continuous, marginally sharply attenuated, lower lip papillae and reflected from jaw, margin of lower lip sharp, covered with firm and hard horny cartilage; a strip of papillae labial plate at chin present. Barbless two pairs. Pharyngeal teeth in three rows. Dorsal fin inserted about opposite to pelvic fins, its last undivided ray osseous, strong and serrated posterior, short than head. Caudal fin deeply emarginated. Scales very small and elliptical; lipids irregular.
Schizothorax prenanti, also known as Ya-fish, is a species of ray-finned fish in the genus Schizothorax from the middle and upper parts of the Yangtze basin in China. It is also known as Yayu, as it is native to the city of Ya'an, Sichuan.
