Abstract
The zooplankton species composition, abundance and biomass in places of the River Płonia′s outflow from lakes were investigated. The zooplankton density and biomass were found to reach 2 million individuals/m3 and 11 g/m3, respectively. A number of seasonal phenomena as well as diurnal abundance fluctuations were found out. The zooplankton removed from lakes was quickly reduced in the river.
