Minicheva were applied. The two methods use one and the same approach, i.e.grouping of species with similar functional characteristics. The results establish,that in conditions of higher level of eutrophication, lowering of biodiversity,disappearing of some species, increasing of number of mesosaprobic andpolysaprobic representatives and tolerant species were registered. Values ofspecific surface increase with higher level of eutrophication. In these conditions,biomass values of macrophytobenthic communities increase and indexes ofphytocoenotic surface decrease.90
