Annotation:
The example of lakes Dabasa-Nur and Lake Kudjartai shows the photosynthetic activity of the plankton of water bodies. The investigated lakes are different in their hydro- chemical composition: Dabasa-Nur is a chloride lake, and Kujartai — a soda lake. The con- tent of chlorophyll a in Lake Dabasa-Nur is less than in Lake Kudjartai. The degraded form of chlorophyll a — pheophytin is presented only in Dabasa Nur. The pigment diversity of lakes plankton dominates by carotenoids as more stable forms of pigments. Chlorophyll c was not found in the plankton of both lakes. Thus, in the modern conditions of the period of restoration of the water content of lakes after a long dry time, the photosynthetic activity of the ecosystem of water bodies is experiencing certain difficulties.
Keywords:
