|Scientific Name:||Poropuntius chonglingchungi|
|Species Authority:||(Tchang, 1938)|
Barbus chonglingchungi Tchang, 1938
|Red List Category & Criteria:||Critically Endangered () B1a+2ab(ii,v) ver 3.1|
|Reviewer(s):||Allen, D.J., Cui, K., Zhou, W. & Chen, X.-Y.|
The species is only known from Fuxian lake and has been impacted by introduced species, the loss of spawning grounds (through the construction of aquaculture ponds and tourism development) and over-fishing. The species has not been collected in surveys since the 1980s and is considered Critically Endangered (Possibly Extinct) as further surveys are required to confirm its extirpation from the lake. The species area of occupancy (AOO) is less than 10 km2 based on the area of spawning grounds.
|Date last seen:||1980s|
|Range Description:||Endemic to Fuxian Lake in Yunnan Province, China. It spawns in the tributary streams, but adults are only found in the lake. No specimens have been collected in thirty years (W. Zhou pers. comm. 2011).|
Possibly extinct:China (Yunnan)

|Population:||The species has not been recorded in surveys for 30 years (W. Zhou pers. comm. 2011). In 1970s, because of a lack of fishery management, all the endemic species in the lake declined, and there was increased competition from the introduced Neosalanx species (X.-Y. Chen pers. comm. 2011).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||The species is found in open water areas of the lake, in the lower layers, periodically in the middle layer. The juveniles are found in the middle layer. It is carnivorous, feeding on shrimps and small fish. Breeding season is from April-August, mostly in June. Spawning ground is at the edges of the lake and in streams with flowing water and a bottom of gravel.|
|Movement patterns:||Full Migrant|
|Use and Trade:||
Fisheries: local consumption and minor commercial fishery.
In the 1970s there was little control over fishery activities, leading to over-exploitation of the lake resources. Invasive non-native species (grass carps, gobies and other small fishes), as well as loss of spawning grounds have also impacted the species.
|Conservation Actions:||More surveys are required to confirm the species extirpation within the lake.|
