摘要：The qualitative and quantitative analysis of the zooplankton of three coastal lakes, .ebsko,
Gardno, and Jamno, was based on materials collected in the 1985-1997 period from June to September. It
was found that the number of zooplankton species, their abundance, and their biomass varied greatly and
were dependent on abiotic factors and lake trophy. An analysis of the structure characteristics of zooplankton
as bioindicators of eutrophication in lakes .ebsko, Gardno, and Jamno revealed the presence in the
zooplankton community of numerous species of rotifers and crustaceans, which are considered to be good
indicators of lake trophy. The progressing eutrophication of the lakes was accompanied by a constant increase
in the numbers and biomass of Rotifera and Crustacea. In all three lakes the zooplankton abundance
was determined by rotifers and biomass by crustaceans. The zooplankton-related trophic state indices
permitted classifying the lakes examined as meso-eutrophic or eutrophic, with symptoms of polytrophy.
