Genetic population structure of vendace (Coregonus albula) in the Gulf of Finland and in adjacent watercourses
Vendace (Coregonus albula) is a freshwater species found in brackish water in the northern Baltic Sea. It has been most abundant in the northernmost part of the Gulf of Bothnia and in the easternmost parts of the Gulf of Finland (GoF), where the stocks have been declining. We assessed the level of g...
