The construction of a thread of reservoirs on the Dnieper River in the middle of the twentieth century allowed to solve a number of important issues related to navigation, supply of water and electric power to industrial facilities, etc. At the same time, the hydrological regime of the river ecosystem underwent radical changes, which significantly affected the species composition of the river. Heating of significant water masses and a high level of their eutrophication made the problem of the Dnieper's "blooming" actual due to the mass development of representatives of photosynthetic cyanobacteria. In the middle course of the Dnieper, the main species, which accounts for the bulk of the organic matter from the “blooming spots” is Microcystis aeruginosa. Subsequent dying of the biomass of cyanobacteria involves a significant part of oxygen dissolved in water in the destruction processes, which leads to its even greater shortage in heated water. This, in turn, provokes the fish and other hydrobionts to be killed. This problem is especially acute for the past 10 to 15 years.enArticle
