PLANKTONIC ALGAE – BIOINDYCATORS OF THE EUTROPHICATION LEVEL OF TWO DAM RESERVOIRS: WAPIENICA AND KOZŁOWA GÓRA
Ewa Jachniak, Janusz Leszek Kozak
In this publication the qualitative structure of planktonic algae was presented. These planktonic algae spread out in two separate dam reservoirs: Wapienica and Kozłowa Góra. There was also presented the biomass largeness of phytoplankton. The estimate of eutrophication was performed by taking into consideration of the indicator taxons; there was used the classification proposing by Heinonen (1980), too. This classification considers the biomass largeness of phytoplankton. The typical taxons for oligotrophic water were observed in the samples of water taking from the reservoir of Wapienica, however the typical taxons for eutrophic water occured in the samples of water taking from the reservoir of Kozłowa Góra. The examinations concerning the average biomass of phytoplankton allowed classification the reservoir of Wapienica to oligo-/mesotrophic reservoirs, but the reservoir of Kozłowa Góra to hipertrophic reservoirs.
