Cyprinus is the genus of typical carps in family Cyprinidae. Most species in the genus are of East Asia origin with only the common carp in Western Asia and Europe; this invasive species has also been introduced to many other regions around the world. Cyprinus are closely related to some more barb-like genera, such as Cyclocheilichthys and Barbonymus (tinfoils). The crucian carps (Carassius) of western Eurasia, which include the goldfish, are apparently not as closely related.
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.
Salangidae, the icefishes or noodlefishes, are a family of small osmeriform fish, related to the smelts. They are found in Eastern Asia, ranging from the Russian Far East in the north to Vietnam in the south, with the highest species richness in China. Some species are widespread and common, but others have relatively small ranges and are threatened. Depending on species, they inhabit coastal marine, brackish or fresh water habitats, and some are anadromous, only visiting fresh water to spawn.
Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae that is endemic to Guangxi, Guizhou and Yunnan in China. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.
Anabarilius polylepis is a species of ray-finned fish in the family Cyprinidae, that is endemic to Yunnan, China. It only occurs in Dian Lake and Songhuaba reservoir in Kunming. It was once a major commercial fish species, but it has not been confirmed in the lake since the 1970s. Its decline is attributed to many factors: introduced fish species, decreasing water quality, the loss of macrophytes, over-fishing, and the loss of breeding sites due to siltation and blocked access.
Anabarilius is a genus of ray-finned fish in the family Cyprinidae, most of them only occurring in the area of China. Many of the species have very restricted geographic range and have been negatively impacted by introduced species, fishing, and habitat degradation; the IUCN Red List includes five Anabarilius species that are either endangered or critically endangered and one species that is considered extinct.
Tor yunnanensis is a species of ray-finned fish in the family Cyprinidae. It is found only in Fuxian Lake in Yunnan, China. It has been severely impacted by the introduced species of fish, pollution, and overfishing, and not seen after the 1990s.
Danio erythromicron, often known as emerald dwarf danio and emerald dwarf rasbora, is a species of cyprinid fish which is endemic to Inle Lake in Myanmar.
Neosalanx is a genus of icefishes native to Eastern Asia, ranging from Korea, through Japan and China, to Vietnam. They inhabit coastal marine waters, estuaries and river basins. There are both species that are threatened and species that are widespread.
Fuxian Lake is a body of water in Yunnan Province, China. It stretches through Chengjiang, Jiangchuan and Huaning Counties, spanning an area of 212 square kilometers. It is the third-largest lake in Yunnan, after Dian Lake and Erhai Lake, and the deepest, at 155 meters. It is the third-deepest fresh water lake in China, after Tianchi and Kanas Lake.
Neosalanx tangkahkeii, the Chinese icefish or short-snout icefish, is a species of icefish endemic to fresh and brackish waters in China. Despite its common name it is not the only icefish in China; the majority of the species in this family are found in the country.
Anabarilius alburnops is a species of ray-finned fish in the genus Anabarilius. It is only known from Dian Lake and Songhuaba Reservoir, both in Kunming, Yunnan. It can reach sizes above 31 cm (12 in) SL.
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.
Anabarilius macrolepis is an extinct species of ray-finned fish in the family Cyprinidae that was endemic to Yilong Lake in Yunnan, China. It is believed that it became extinct when Yilong Lake dried up in 1981, as a result of water abstraction for agriculture. The species was not observed in 1983–84, and was declared extinct in 2011.
Anabarilius maculatus is a species of cyprinid fish in the family Xenocyprididae. It is endemic to the Nan Pan Jiang basin in Yunnan, southern China. It is threatened by invasive non-native species, domestic and urban waste water, agricultural pollution and dams. The species have not been studied well, therefore its ranked as Data Deficient. It grows to 13.9 cm (5.5 in) standard length.
The golden-line barbel is a species of cyprinid fish endemic to Dian Lake and its tributaries in Yunnan, China. It has been extirpated from the lake itself due to heavy pollution, but survives in a single tributary and a few small temple ponds. This species can reach a length of 23 centimetres (9.1 in) though most are only around 17 centimetres (6.7 in). The greatest weight known for this species is 250 grams (8.8 oz).
Sinocyclocheilus tingi is a species of freshwater fish in the family Cyprinidae. It is only known from Fuxian Lake in Yunnan. It grows to 18.3 cm (7.2 in) SL.
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.
Abbottina rivularis, also known as the Chinese false gudgeon or the Amur false gudgeon, is a species of ray-finned fish in the family Cyprinidae, the carps and minnows. It is native to China, Korea, and Japan, but it has been introduced to the Mekong River Basin and is also known from rivers in Turkmenistan.
Hemisalanx brachyrostralis is a species of icefish endemic to the Yangtze basin, China. It is the only known species in the genus Hemisalanx, after Hemisalanx prognathus was moved to genus Salanx. In a study of the five freshwater icefish species in the Yangtze, it was a relatively low-density species, being much less frequent than Neosalanx taihuensis and N. oligodontis, but more than Protosalanx hyalocranius and N. tangkahkeii. H. brachyrostralis reaches up to 13.6 cm (5.4 in) in total length.
