A population of Anodonta grandis (Bivalvia; Unionidae) in a small Arctic lake was sampled in 1973 and 1986. In both of the years sampled there were about 14 times more mussels in deep (> 1.5 m) water than in shallow Water There was a decline in growth rate, a shift towards an older age structure, and a drop in population density from 2.3 to 0.65 animals per∙m−2 between 1973 and 1986. This pattern is consistent with an hypothesis of anthropogenic impact. The limitations of such an interpretation are discussed.
