Europe: Austrian subalpine Lakes Attersee, Mondsee and Wolfgangsee; a small population in Austrian stretch of Danube. Extirpated in Lakes Traunsee in Austria and Chiemsee in Germany. Rutilus populations of uncertain identity from upper Tisza system (Slovakia, Hungary) might belong to this species.

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Differs from its congeners in Danube drainage by having the following unique characters: almost cylindrical body, 62-67 + 3-4 scales along the lateral line, abdomen posterior to pelvics rounded, in breeding males large, scattered tubercles on top and side of head. Other characters useful to distinguish this species include the following combination of characters: rounded and stout snout, subterminal mouth, grey or slightly yellowish iris and fins, and 8-9 ½ branched dorsal rays (Ref. 59043).
Occurs in subalpine lakes. Preys on benthic invertebrates. Breeds in lake tributaries or streams connecting lakes in shallow areas with current and near shore. Has been extirpated since 1980 from two of five lakes it originally inhabited (Ref. 59043).
