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 typical spawning season for Coregonus albula is autumn, but certain North European lakes have populations of vendace that spawn in the spring, some of which have been classified as distinct species: in Sweden, they are known as Coregonus trybomi, and two lakes in northern Germany are home to Coregonus fontanae and Coregonus lucinensis.
