Cyanophyta blooms in Koronowski Reservoir in the background of environmental conditions
On the basis of floristic analysis, the occurrence of 132 taxons of plankton algae in Koronowski Reservoir was determined. The spring and autumn plankton was dominated by diatoms, while summer plankton by blue-green algae. The species composition, structure of the abundance of algae and concentration of chlorophyll as well as physicochemical conditions of water suggested a highly eutrophic character of this reservoir with a starting expansion of blue-green algae, mainly species considered to be toxic.
