Abstract

© 2019, Dorma Journals. All rights reserved. The article presents the results of studies of planktonic algae of ponds, located within the city of Vyksa, for 2017-2018. During the period of observation, 110 taxa were found in the phytoplankton of the studied water bodies. Phytoplankton was formed by diatoms, green, blue-green and euglena algae. The highest values of the abundance and biomass were typical for the Vil'skiy pond. The lowest values of the abundance and biomass were observed in the Verkhnevyksunsky pond. The quality of water in majority of the studied reservoirs was estimated as mesosaprobic. According to the indicators of water trophicity, most of the studied objects are mesotrophic. The highest values of the indices of saprobity and trophicity were defined in the Vil'skiy pond, the water quality of which corresponded to the eutrophic and hypereutrophic types.
