Assessment of the current state of the ecosystem Zelvyansky reservoir according to the results of biomonitoring
Abstract
Biomonitoring of the state of the ecosystem of the Zelvyansky reservoir was carried out. The hydrochemical regime, composition and degree of development of aquatic communities. The degree of overgrowth of the reservoir, the species structure and quantitative development of phyto-, zooplankton and zoobenthos were determined, and the eutrophic type of the reservoir was confirmed. It was established that over a thirty-year period, zooplankton production decreased almost twice under the influence of planktivorous fish, the number and biomass of zoobenthos increased more than three times due to mollusks, and the hydrochemical regime of the reservoir did not undergo significant changes.
