Anabarilius polylepis is a species of ray-finned fish in the family Cyprinidae, that is endemic to Yunnan, China. [1] [2] It only occurs in Dian Lake and Songhuaba reservoir in Kunming. It was once a major commercial fish species, [1] but it has not been confirmed in the lake since the 1970s. [3] Its decline is attributed to many factors: introduced fish species, decreasing water quality, the loss of macrophytes (partly caused by the introduced grass carp), over-fishing, and the loss of breeding sites due to siltation and blocked access. [1]

Anabarilius polylepis grows to 22.7 cm (8.9 in) standard length. [2] It lives in the uppermost ten metres of the water column and feeds mainly on aquatic insects, plankton, and plant fragments. [1]

Dian Lake Body of water

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 .

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.

Yilong Lake is a large freshwater lake located in Shiping County, Honghe Prefecture, Yunnan province, southwestern China. The lake has a surface area of approximately 32 square kilometres (12 sq mi) and is particularly notable for its scenery, including the colorful lotus flowers that bloom on its surface. It is located about 2 kilometres (1.2 mi) east of the county seat. The people who live in the vicinity of the lake are largely of the Yi ethnic group. As of the spring of 2013 a severe drought had resulted in substantial lowering of the water level.

Anabarilius is a genus of ray-finned fish in the family Cyprinidae, most of them only occurring in 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.

Cyprinus micristius, the Dianchi carp, is a critically endangered species of ray-finned fish in the family Cyprinidae. It is found only in Lake Dianchi and its tributaries in Yunnan, China. The nominate subspecies from the lake itself has not been confirmed since the 1960s.

Sphaerophysa dianchiensis is a critically endangered species of stone loach endemic to the Dian Lake in China, but it has not been confirmed in decades and is likely extinct.

The Kunming catfish is a critically endangered species of catfish in the family Siluridae. It is endemic to Dian Chi Lake, China. There have been no confirmed records in decades and it is feared extinct. S. mento grows to a length of 21.5 centimetres (8.5 in) TL.

Fuxian Lake Body of water

Fuxian Lake stretches out through Chengjiang, Jiangchuan and Huaning Counties in Yunnan Province, spanning an area of 212 square kilometers. The lake is ranked third-largest in Yunnan, after Dian Lake and Erhai Lake. Also the deepest lake in Yunnan, it is 155 meters deep at its greatest depth. It is also 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 Alburnus. 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 andersoni is a species of cyprinid fish that is endemic to China. It is a pelagic species only known from Xingyun Lake in Yunnan, and its population is severely impacted by domestic pollution and overfishing.

The Kanglang fish is a species of cyprinid fish. It is a pelagic species endemic to Fuxian Lake in Yunnan, southern China. However, the species may now be in the process of extinction because of the introduced noodlefish Neosalanx taihuensis, with which it is competing for food.

<i>Anabarilius macrolepis</i> Extinct species of fish

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 ot 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.

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.

Anabarilius xundianensis is a species of cyprinid fish in the family Xenocyprididae. It is endemic to Yunnan (China). It is known from Qingshui Lake in the eponymous Xundian County, on the Jinsha River. The exact threats are unknown but it may be fished for food and sensitive to pollution.

Anabarilius yangzonensis is a species of cyprinid fish in the family Xenocyprididae that is currently critically endangered. They can only be found in Yangzong Lake of Yunnan, China.

Cyprinus barbatus is a species of ray-finned fish in the genus Cyprinus. It is endemic to Lake Erhai in Dali, Yunnan, China. It is negatively impacted by agricultural and domestic pollution and introduced species. The IUCN considers it as critically endangered and possibly extinct, but records as recent as the 2000s (decade) show that it likely does survive.

Liobagrus kingi, the King's bullhead, is a species of catfish in the family Amblycipitidae endemic to China, where it is known to occur in the lake Dianchi basin, in its tributaries and effluent river, the Zhangjiu, and two tributaries of the Jinshajiang river in Sichuan and Yunnan. It has not been recorded in the lake since the 1960s. This species grows to a length of 9.5 centimetres (3.7 in) SL.

Caridina yilong is a species of freshwater shrimp in the family Atyidae. C. yilong was described from Lake Yilong in Yunnan, China, and was believed to be endemic to the margins of the lake among fringing vegetation. Only the type series has ever been collected, and the type locality of Lake Yilong has since dried up for extended periods of time due to the abstraction of water. Organic pollution caused by sedimentation along with agricultural and industrial pollution have caused this species to be assessed as Critically Endangered by the IUCN, with the caveat possibly extinct. In addition, two species of fish, Anabarilius macrolepis and Cyprinus yilongensis, that also were endemic to the lake are now extinct.
