Distribution: Europe: In the Baltic Sea: Swedish coast (including Bothnian Gulf, not in Gotland); in southern Baltic, extending from the Schlei to Gulf of Finland. Southeast North Sea Basin: Ems, Weser and Elbe drainages and small rivers of Schleswig-Holstein and Denmark. Landlocked in several lakes in Poland, Sweden, and Russia. Introduced and transplanted in many drainages within its native range and outside westward to Rhine drainage (Ref. 59043). Apparent abundance in Germany, Poland and Scandinavia results from the massive stocking programs without which the populations would rapidly decline. Usually known as C. lavaretus in the Baltic Sea basin. North Sea population might represent a distinct species (Ref. 59043).
