Coregonus vandesius, the vendace
Taxonomy
Most authorities now consider Coregonus vandesius to be a subjective synonym of Coregonus albula, which is a more widespread North European freshwater whitefish species.[2] Both taxa are also known by the common name vendace. The status however remains controversial, and FishBase still lists C. vandesius as a separate species,[3] reflecting the recent treatment of the European freshwater fish fauna by Kottelat & Freyhof (2007).[4] Another synonym of British C. vandesius is C. gracilior.[3]
The name "vendace" (
Biology
Coregonus vandesius inhabits deep, cold lakes, and uses planktonic crustaceans, such as copepods, as its primary food source. The fish does not migrate and has a life span of about six years. The species is now Britain's rarest fish.[2]
Distribution and habitat
The vendace has only ever been known as a native species at four sites in Britain:
Status
This fish has a restricted range, with a total area of occupancy of less than 500 km2 (190 sq mi). The current population trend is unknown and the main threats are thought to be eutrophication and the introduction of alien species. The International Union for Conservation of Nature has rated its conservation status as being "endangered".[1]
