Abstract
As a result of long-term studies of the content of photosynthetic pigments in periphyton algae in the Amurskaya channel of the Amur River during a period of high water level, it was found that chlorophylls predominate in the pigment fund, its basis is chlorophyll a (68 %). The interannual and seasonal dynamics of photosynthetic pigments has a cyclical nature, in which an increase in their content is observed in spring and autumn, after the passage of fl oods and the establishment of low water, and a decrease occurs in summer during fl oods. The trophic status of the channel according to the weighted average values of chlorophyll a concentration over the growing seasons is estimated as mesotrophic (second quality class, clean waters). The Amurskaya channel, previously classifi ed as a hypereutrophic watercourse, changed its status to eutrophic.
