Spatial Distribution of Zooplankton on the Upper Part of the Cheboksary Reservoir

Resumo

The modern state of the species structure and spatial distribution of zooplankton cenoses in the upper part of the river hydraulics zone in the Cheboksary Reservoir, where the construction of a low-head dam is planned, and in the mouth part of the Oka River has been studied based on the data of 2016 and 2017. Two zooplankton communities have been identified in these areas; differences in their species structure are determined by several ecological factors: total mineralization, water transparency, temperature, pH, etc.
