Hydrological and hydrochemical studies of the hydrobionts habitat on freshwater reservoirs of the Central part of Russia in 2017

Abstract

The paper contains information on expeditions conducted in 2017 on the water reservoirs and rivers of the Moscow, Tula, Ryazan, Orel and Smolensk regions to assess the abiotic indicators of the habitat of aquatic living resources. The characteristic of the hydrological and hydrochemical conditions of aquatic living resources during different seasons of 2017 is given. According to hydrochemical indicators it is shown that the majority of studied water reservoirs can be referred to water reservoirs with favorable ecological conditions for fish habitat. The exceptions were the waters of the Khimki, Shatsky and Lyubovsky reservoirs and the Oka River in the vicinity of Orel and Kolomna, which were characterized as “dirty” due to high anthropogenic pollution.
