ARTICLE ANNOTATION

quote
The development, distribution and formation of phytoplankton in reservoirs depends on the complex effects of environmental factors. In the phytoplankton of the Akdarya reservoir, 71 species and species are identified, which belong to 4 divisions (Cyanophyta, Bacillariophyta, Xantophyta, Chlorophyta). Phytoplankton is very abundant in the autumn period of the year, at this time there are 32 species and varieties, they are 42.25%. In the winter period of the year, the smallest indicator was 2 types (2.81%). In the remaining periods of the year, intermediate indicators were observed (in the spring of 23 species, 32.39%, in the summer of 25 species, 35.21%). The diversity of phytoplankton species composition at different periods of the year depends on temperature, water salinity and other factors. In general, in the phytoplankton of the reservoir, 52% of algae are freshwater, 24% freshwater-saltwater, and 24% saltwater.
