Abstract

he article studies the algal flora of Kolsai lakes and provides a biological assessment of their stateby the bioindication method. There are 124 species from 6 microalgae divisions were found in thealgal flora of investigated lakes. The greatest number of species (72) is recorded in the first Kolsai lake,including diatoms – 41 species, green – 19 species and blue-green – 12. In the composition of second Mynzholka Lake’s algal flora, there are 52 species belonging to four divisions: Bacillariophyta – 24 species, Cyanophyta – 9 species, Chlorophyta – 14 species and Dinophyta – 5 species were identified. Themost numerous and diverse in a specific respect are the diatoms (Bacillariophyta), the division is represented by 14 genera and 7 families. In the Upper Kolsai there is a relatively smaller species diversity – 45species belonging to 5 divisions, 10 classes, 13 orders. At the same time, the largest number of speciesis also represented by the diatom algae division, totally 31 species were found. It is established that thespecies richness of Kolsai lakes’ algae varies depending on the location of the studied places, so the algal species’ composition characterized by relatively high diversity in the Lower Kolsai Lake, located atthe altitude 1818 m above sea level. Analysis of indicator-saprobic species of Kolsai lakes testify to theabsence of signs of contamination in them. Indicators of pure water – oligosaprobes here were the mostnumerous. The index of saprobity fluctuate within 1.15-1.5, which corresponds to oligosaprobic conditions of the medium.Key words: algal flora of microalgae, bioindication, saprobity index.
