Justification
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.

Population

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).

Threats

Major Threats

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.
