Thirty two taxons have been identified of 13 genera, 10 families, 2 classes of Cyanophyta division. Twenty nine of them were identified for the first time in the Vakh river. Anabaena spiroides species hasn't been found in the studied samples. Taxonomic composistion and ecological characteristics of planktnonic cyanobacteriae found in the Vakh river are considered
