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.
