; Nước ngọt; Thuộc về nước lợ gần đáy; pH range: 7.0 - 7.5; dH range: 20 - ?; di cư biển sông (để đẻ trứng) (Ref. 51243). Temperate; 4°C - 16°C (Ref. 2059); 78°N - 41°N, 6°W - 85°E
Europe: Native to Lake Bourget (France) and Geneva (Switzerland, France). Population of Lake Aiguebelette (France) apparently introduced, but a 'lavaret' had already been recorded from there in the 17th century (Ref. 59043). 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 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). Asia: introduced to Iran (Ref. 39702).
