Abstract

Seasonal investigations of quantitative and qualitative parameters of phytoplankton symbiosis of the Akhpara reservoir was carried out in 2015. It was revealed that more than 45% of recorded algae were indicator species of organic pollution. According to surface waters classifications by trophic and saprobic (eco-sanitary) indices, the water of the Akhpara reservoir was changed from β-oligosaprob level (spring) to β-mesosaprob level (summer, autumn), which indicated that in summer and autumn the level of organic pollution increased. As a result of the study, has been revealed that the number of large single-celled and colonial species in phytoplankton community in 2015 increased compared with previous years.
