Growth and age structure of the swan mussel Anodonta cygnea (L.) at different depths in lake Mattsee (Salzburg, Austria)

Unionid clams were collected at 1-2 m, 3-4 m and 6-7 m depth in Lake Mattsee, a moderately mesotrophic lake, to investigate the effect of depth on clam growth and age structure. No significant differences in age structure of Anodonta cygnea were found (p = 0.65). Three and ten years old clams were p...

Zusammenfassung:Unionid clams were collected at 1-2 m, 3-4 m and 6-7 m depth in Lake Mattsee, a moderately mesotrophic lake, to investigate the effect of depth on clam growth and age structure. No significant differences in age structure of Anodonta cygnea were found (p = 0.65). Three and ten years old clams were present at all depths, but in different percentages. Whereas at 1-2 m 13.3% of the collected clams were
