Abstract

The paper considers the influence of abiotic factors on the formation of ichthyofauna of freshwater ecosystems. The importance of hydrological, temperature, optical and gas regimes of water bodies in the formation of the structure of ichthyocenoses is shown. It is established that changes in the hydrological regime, water transparency and oxygen balance affect the conditions of existence, reproduction and food base of fish, which determines the number and species composition of populations.
