Floristic composition of riparian freshwater communities in various sections of the Shoshinsky and Volzhsky ples of the Ivankovsky reservoir and its role in the formation of a food base for the fish community

The floristic composition of riparian freshwater communities in various sections of the Shoshinsky and Volzhsky ples of the Ivanko reservoir has been studied. It is shown that the species composition of heliophytes, hydatophytes, and hydrophytes is similar and differs only in the area of overgrowth. On the Shoshensky Reach at the mouth of the Lama River, Puzyrevo tract, Dubki Bay and Kabanovo Island, it is about 70-80%. In the Volga Basin, such areas are found only in shallow bays, backwaters, and islands. Along the banks of the main channel of this reach, thickets of heliophytes do not exceed a width of 3-5 m. The indicators of the abundance and biomass of zooperiphyton in monodominant thickets of cattail, redwood and theloresis have been determined. The role of florists in the improvement of spawning grounds and feeding grounds for the fish community is assessed. Data on the fish productivity of the surveyed sites are presented.
