Schizothorax heterochilus is a species of ray-finned fish in the genus Schizothorax from the upper parts of the Yangtze basin in China. [3]
The Yangtze or Yangzi is the longest river in Asia, the third-longest in the world and the longest in the world to flow entirely within one country. It rises at Jari Hill in the Tanggula Mountains and flows 6,300 km (3,900 mi) in a generally easterly direction to the East China Sea. It is the sixth-largest 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 Chinese swordfish, is a reportedly extinct species of fish that was native to the Yangtze and Yellow River basins in China. At maturity, the species measured an average length of 3 m (9.8 ft), making it one of the largest species of primarily freshwater fishes. It was the only species in the genus Psephurus and one of two living species in the paddlefish family (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. Unlike its close relative, the Chinese paddlefish was largely piscivorous, and mainly preyed on small to medium-sized fish.
Dianchi Lake, also known as Lake Dian and Kunming Lake, is a large lake located on the Yunnan-Guizhou Plateau close to Kunming, Yunnan, China. Its nickname is the "Sparkling Pearl Embedded in a Highland" and it was the model for the Kunming Lake in the Summer Palace in Beijing. 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, Chiangjiang 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 in the early 1980s, it was designated an endangered species on the Chinese Red List and commercial harvest was banned. It has been listed as a Critically Endangered species by the IUCN since 1996.
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 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.
The Nepalese snowtrout is a cyprinid fish species of the genus Schizothorax. This snowtrout was first collected in 1979 in the alpine fresh water Rara Lake located in Nepal's Rara National Park.
The blunt-nosed snowtrout is a species of ray-finned fish in the genus Schizothorax from the Brahmaputra River drainage in India and China, where its is heavily exploited for food.
Schizothorax nepalensis is a cyprinid fish species of the genus Schizothorax. It was first collected in 1979 in the alpine fresh water Rara Lake located in Nepal's Rara National Park.
The Transcaspian marinka is a species of ray-finned fish in the genus Schizothorax from Afghanistan, Turkmenistan and Iran.
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.
