Abstract

Human population oftenly distorts the balance of freshwater ecosystems, which results in eutrophication and accelerated degradation of aquatic habitats. This paper considers three basic methods of restauration – physical, chemical and biological, and their advantages and disadvantages. Physical methods are used to remove the sediment/water from the lake, chemical methods are used to reduce a concentration of the nutrients in the water column by applying chemicals, and biological methods are used to manipulate the composition of biocenosis. Usually a fish manipulation and reestablishment of macrophites are applyed The goal of restauration is to achieve a predominance of submerged macrophytes over phytoplankton, which results in the return of water transparency and balanced ecosystem.
