:*Coregonus vandesius, in lakes of Scotland and England; arguably the same species as Coregonus albula
Coregonus albula generally breeds in the autumn, but in several North European lakes distinct spring-spawning populations of vendace exist, some of which have been described as separate species: in Sweden, as Coregonus trybomi, and in two lakes of northern Germany, as Coregonus fontanae and Coregonus lucinensis.
The vendace has only ever been known as a native species at four sites in Britain: Bassenthwaite Lake and Derwent Water in the English Lake District, and the Castle Loch and Mill Loch in Lochmaben, Scotland.
The lake is believed to be the last remaining native habitat of the vendace (Coregonus vandesius) fish from the 4 originally known sites: Bassenthwaite Lake and Derwent Water in the Lake District and the Castle Loch & Mill Loch in Lochmaben.
48 forms (species and infraspecific taxa) of fish have been encountered in the lake, including roach, carp bream, zander, European perch, ruffe, endemic variety of smelt, two varieties of Coregonus albula (vendace), eight varieties of Coregonus lavaretus, a number of other Salmonidae as well as, albeit rarely, endangered European sea sturgeon.
