TAXONOMIC COMPOSITION OF FILAMENTOUS ALGAE IN CHEREK WATER BASIN
The taxonomic belonging of filamentous green algae and the degree of their confinement to the substrate and water depths have been studied. The biomass, concentration territories and areas of filamentous algae thickets have been determined. It is found that the most important and practically the only source of the above algae primary production in water bodies is photosynthesis realized by the phytoplankton community. There were identified 50 species of filamentous algae belonging to 4 classes: ulotrixic, siphon, conjugate and protococcal ones. On the basis of empirical points, there was constructed a theoretical regression line, reflecting the dependence of the calculated production value on the terms of exposition.
