 abstract={The occurrence of bivalves of the family Unionidae was analysed in 16 ox-bow lakes of the Bug River (The Bug River Valley Landscape Park) in the years 2003–2005. One to four species were found in 12 of the lakes. Unio pictorum (L.) was the dominating species in 5 and Anodonta anatina (L.) – in 3 lakes. Other frequent species were U. tumidus Philipsson and A. cygnea (L.). U. crassus Philipsson was found in only one of the ox-bow lakes. Most frequent densities noticed were around 10 ind./m2 and the maximum density was over 200 ind./m2.},
