Abstract

Qualitative and quantitative structures of benthic macro-invertebrates, macrophytes, zooplankton, as well as ichthyofauna and fish parasites of the shallow areas of Small Sevan that flooded as a result of an increase in the lake’s water level are analyzed. It is shown that the most appropriate conditions for the development of hydrobionts were found in the area that was flooded earlier and is directly connected with the lake. In contrast, the worst conditions occurred in the area that was flooded later and is minimally connected with the lake.
