coregonus albula
''Coregonus albula'', known as the vendace or as the European cisco, is a species of freshwater whitefish in the family Salmonidae. 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 also found in diluted brackish water in the Gulfs of Finland and Bothnia, both of which are in the Baltic Sea.
The length of an adult is normally about . The maximum age 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, which has been granted a PDO status in the Swedish Bothnian Bay archipelago (Kalix löjrom).
==Description==
The vendace is a slim, streamlined fish with an adipose fin - an additional small fin on the back between the dorsal fin and the tail (caudal fin), as is typical of the salmon family. Its lower jaw is longer than the upper one. It is similar in appearance to both the common whitefish (''Coregonus lavaretus'' sensu lato), whose upper jaw is longer than its lower one, and the peled (''Coregonus peled''), whose jaws are of equal length. The back is bluish green or brown, the flanks are silvery and the belly white. This fish seldom grows more than long.〔(【引用サイトリンク】title=Vendace: ''Coregonus albula'' (L.) )〕
