Assessment Information [top]

Red List Category & Criteria: Critically Endangered A2bcde ver 3.1
Year Published: 2009
Date Assessed: 2007-03-01
Assessor(s): Devi, R. & Boguskaya, N.
Reviewer(s): Collen, B., Darwall, W., Ram, M. & Smith, K. (SRLI Freshwater Fish Evaluation Workshop)
C. fuxianensis has been assessed as Critically Endangered, and is suspected Possibly Extinct as it has been estimated that the population has declined by over 80% in the past 21 years, as a result of habitat degradation, overfishing, and introduced species. During survey work in 1995 no specimens were caught (F. Fang, pers. comm.). C. fuxianensis has a restricted range (less than 200 km²) and is only found in one location.

Population [top]

Population: C. fuxianensis is very rare, possibly extinct, in the lake since population declines as a result of competition and hybridisation with introduced species, overfishing and pollution. During survey work in 1995 no specimens were caught (F. Fang, Pers. Comm.). It is suspected that the population has declined by over 80% in the past 21 years.
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: C. fuxianensis is a benthopelagic species.
Systems: Freshwater
Generation Length (years): 6-7

Threats [top]

Major Threat(s): Fuxian Lake is heavily impacted by overfishing and pollution from domestic and industrial sources, which became major threats in the 1980s. Tourism is one of the major industries around the lake.

Cyprinus carpio was introduced into the lake in the 1980s to improve fishery catches, and has hybridised with and outcompeted C. fuxanensis.
