| Popis: | Seasonal studies of phytoplankton community in the middle course part of Hrazdan River were performed in 2018. Eighty species of algae from 6 groups were identified. Diatoms were the dominant and Cyanophytas – subdominant group of the river’s phytoplankton community. Maximum abundance of algae was registered in autumn. The river is considered “moderately polluted” according to the Shannon – Weaver water quality index and mainly “beta-mesosaprobic” based on the level of organic pollution according to the saprobic index. |
