Streszczenie w języku polskim
The occurrence of the bivalve Dreissena polymorpha in seven mesotrophic lakes of the Masurian Lakeland was evaluated. There were great differences between lakes in the D. polymorpha populations; they involved the numbers, biomass, occurrence zone and age structure of the settled individuals. The numbers of planktonic larvae, measured in three lakes, greatly differed. One lake (Majcz Wielki) was characterized by the greatest differences in the planktonic larvae numbers between years of studies.
