Studies carried out on 8 lakes in the Łęzna-Włodawa Lakeland of eastern Poland indicated that the qualitative and quantitative structure of zooplankton was clearly correlated with the lake trophic state. In the spring zooplankton of lakes affected by gradual natural eutrophication were dominated by rotifers. In the zooplankton of lakes strongly affected by human activities, Cladocera dominated. With an increase in lake trophy there was an increase in the number of species that were indicators of eutrophy and a decrease in the number of indicators of mesotrophy. The total number of species in individual lakes tended to increase with an increase in trophy.
