摘要：The qualitative and quantitative analysis of the zooplankton of coastal lakes was based on
materials collected in the months of July and August from 1985 to 1988. It was found that the numbers
of zooplankton species and their abundance and biomass were greatly variable and depended on abiotic
factors and the trophic state of the lakes. An analysis of the structural characteristics of the zooplankton
for potential bioindicators of eutrophication in these coastal lakes revealed the presence of some species
of rotifers and crustaceans in the zooplankton community that could be considered good indicators of
trophic state. The progressive eutrophication of the lakes was accompanied by a constant increase in the
numbers and biomass of Rotifera and Crustacea. In the majority of the lakes zooplankton abundance was
determined primarily by rotifers and biomass by crustaceans. The zooplankton-related trophic state indices
enabled classifying most of the investigated lakes as eutrophic or mesoeutrophic.
