Abstract:
The influence of abiotic factors on the seasonal dynamics of phytoplankton has been studied. An assessment of the trophic state of the river is given. Kama (Kama Bay of the Kuibyshev Reservoir). The seasonal values of the main environmental factors influencing the dynamics of phytoplankton (level regime, intensity of incident solar radiation, a number of basic hydrochemical and hydrophysical indicators) are analyzed. The waters of the study area of the river. Kama during most of the growing season corresponded to the mesosaprobic type and moderately polluted zone.
