The vendace, Coregonus albula, is a species of freshwater whitefish in the family Salmonidae. It is also known as the European cisco. It is found in lakes in northern Europe, especially Finland, Sweden, Russia and Estonia, and in some lakes of the United Kingdom, northern Germany and Poland. It is found also in diluted brackish water in the Gulf of Finland and the Gulf of Bothnia of the Baltic Sea.[2] Vendace mainly feed on zooplankton, such as small crustaceans and their larvae. The fish live in schools made up of large groups of individuals. They lay their eggs on pebbly or sandy ground. The length of an adult is normally about 25 centimetres (9.8 in). The maximum age reached by this fish is about ten years. The vendace is traditionally the most important target of freshwater fisheries in parts of Fennoscandia and Russia. Vendace roe is considered a delicacy and the famous "Kalix löjrom" (Kalix vendace roe) is produced in the Swedish Bothnian Bay archipelago. Taxonomy According to FishBase, the British populations of vendace are a separate species, Coregonus vandesius,[3] but this distinction is not accepted by all scientists.[4] 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. These populations are sympatric with autumn-spawning vendace, and seem to have evolved post-glacially from them independently in each lake.[5][6] References 1. ^ Freyhof, J. & Kottelat, M. (2008).
