Abstract

The study reports the first records of the duck mussel Anodonta anatina (Bivalvia, Unionidae) in the Irkut River basin. The morphometric characteristics of the shells of this species collected from the Irkut and Angara rivers are analyzed. The shell height to length ratio (H/L index) was within 0.44–0.65 for the valves from the Irkut and 0.47–0.67 for the valves from the Angara. These data are consistent with previously published measurements of modern European and Transbaikal A. anatina, as well as Pleistocene duck mussel shells from Eastern Siberia. Bivalves from the Irkut and Angara basins did not show significant differences in shell shape and nacre color, since these populations live in almost identical conditions: artificial lakes and the quarry with similar soils and water temperatures
