A heavy otter predation on the swan mussel was recorded in early spring in a fish-pond in SW. Poland. Although natural predation was not regarded as a threat to the swan mussel in Poland, it is likely that in areas where the otter (and possibly also mink, raccoon and muskrat) is common the mussel’s populations may suffer heavy losses.

Dead individuals of Chinese mussel Sinanodonta woodiana (Lea) were found in 2009 in the complex of fishponds in Spytkowice (S. Poland) in the Vistula River valley. Earlier records of this invasive alien species in Poland come mostly from heated waters. Its occurrence in fishponds indicates that it tolerates also colder waters; many aquatic ecosystems in Poland may be threatened with its invasion. Endangered swan mussel Anodonta cygnea (Linnaues) was found in the same fishponds. The species had not been reported from his area before and it is uncertain whether persistence of its population here is threatened by the invasion of Chinese mussel.
