Аннотация: It is shown that in the area inhabited by a colony of the common heron in a high-trophic shallow lake a number of structure parameters of plankton undergoes changes similar to those observed at anthropogenic eutrophication and indicating an increase in biogenic and organic load. At the same time a number of changes is revealed thatПоказать полностьюare usually not registered when human influence increases. The composition and content of polyunsaturated fatty acids in seston and zooplankton show that diatoms and detritus of land genesis play relatively smaller role in the zooplankton nutrition in the lake area influenced by the birds. The zooplankton developing in this zone is a better food rich in essential docosahexaenoic acid necessary for the growth and development of the fish.
