Coregonus lavaretus (Linnaeus, 1758)
Family:	Salmonidae (Salmonids) , subfamily: Coregoninae	picture (Colav_u2.jpg) by Caramori, G.
Order:	Salmoniformes (salmons)
Class:	Actinopterygii (ray-finned fishes)
FishBase name:	Common whitefish
Max. size:	73.0 cm TL (male/unsexed; Ref. 40637); max. published weight: 10,000 g (Ref. 35388)
Environment:	demersal; anadromous; pH range: 7 - 7.5; dH range: 20
Climate:	temperate; 4 - 16°C; 73°N - 40°N
Global Importance:	fisheries: commercial; aquaculture: commercial
Resilience:	Medium, minimum population doubling time 1.4 - 4.4 years (K=0.3-0.7; tm=3-4;)
Distribution:	Europe: usage of name restricted to Lakes Genève (now extinct), Bourget, and Aiguebelette in the river Rhône basin by designation of neotype from this area (Ref. 13696). Other authors assume it to be a superspecies occurring in Great Britain and Alpine areas of Central Europe. Has been stocked into many other places in Europe outside of its native range. There are many parallel and wrong scientific names for this species in use because of the problems in classifying the genus Coregonus (Ref. 7495). Appendix III of the Bern Convention (protected fauna). Asia: introduced to Iran (Ref. 39702).
Diagnosis:	Dorsal spines (total): 3-5; Dorsal soft rays (total): 9-12; Anal spines: 3-5; Anal soft rays: 10-13. Mouth small with protruding upper jaw. Silvery body (Ref. 35388). Caudal fin with 19 soft rays (Ref. 40476).
Biology:	Gregarious lacustrine forms (Ref. 2163) and anadromous estuarine forms, rarely in full saltwater. Feeds on planktonic crustaceans, or larger benthic crustaceans in brackish water. Movement in water column as a function of zooplankton repartition. Likely to benefit from environmental regulations in France passed on 8/12/88 (Ref. 2163)
Threatened:	Vulnerable, see IUCN Red List (D2) , (Ref. 36508)
Dangerous:	harmless
Coordinator:
