Abstract

GIS technologies are used to determine the boundaries and areas of the deep-water zone, thickets of higher aquatic vegetation, and open-water zones with different types of soils in the river section of the Sheksninskoe Reservoir. Quantitative characteristics and the composition of the surveyed zoobenthos species in each type of biotope are given. In the bays, the zoobenthos biomass is lower than in similar biotopes in flowing areas along the shipping channel. The weighted average biomass of zoobenthos is 3.9 g/m2. By the level of zoobenthos development, the abundance of food in the reservoir is classified as medium.
