In order to implement the provisions of the EU Water Framework Directive 2000/60/EU, the theoretical and methodological principles of applying the method of instantaneous biomonitoring of the stability of aquatic ecosystems development on the basis of evaluation of macrophyte fluctuating asymmetry indicators were proposed. The research found that the violation of the stable development of ecosystems, including the influence of anthropogenic factors, causes deviation in the morphological parameters of higher aquatic plants. Violations of the symmetry of individual parts, namely morphogenetic changes in macrophytes, are closely related to the coefficients of ecological stabilization of landscapes and the water quality categories. The qualitative assessment of the environment in terms of fluctuating asymmetry of indicator plants is justified in relation to salt composition, trophoscopic and toxicity indices. The particular sensitivity of this method has been found in relation to the content of heavy metals in the mules and coastal soils at concentrations below the established maximum permissible concentrations (MPC). The regularities of the distribution of the integral fluctuating asymmetry indices are determined and a three-dimensional model of the asymmetry formation in a leaf of Potamogeton perfoliatus is established, depending on the stability of the landscapes and water quality. They represent the basic short-term component of the integrated system of biomonitoring of sustainable development of aquatic ecosystems and allow clarifying, correcting and generalizing the existing methods for environmental assessment of water quality. The proposed technique allows strengthening the role of the biological component in conducting an environmental assessment of the quality of surface water and ensures the implementation of the EU Water Framework Directive 2000/60/EU on the territory of Eastern Europe.
