The planktonic protozoa, especially ciliates, were analysed in five mining lakes of various pH and acidity values in the Lusatian and mid-German mining area. Heliozoa were the main protozoan component in the very low pH (< 2.9) lakes. In the lakes with pH > 2.9, the ciliate community consisted of Hypotrichida, Prostomatida and Peritrichida. The species diversity of the ciliate community was reduced and typical representatives of plankton ciliates were lacking. During periods when populations were at their peak, the cell numbers and biomass of ciliates were comparable to those neutral lakes, reaching maximum values of 30 000 cells l(-1) and 0.3 mg l(-1). Cell numbers and biomass peaks appeared without a clear seasonal pattern but in some cases a correlation to phytoplankton dynamics was recognizable.
