Methodological approach to the water quality and ecosystem health from the ecological paradigm position has been vindicated. Critical analysis of the currently existing methods of water quality assessment has been performed. It has been shown that biological criteria of the ecosystems’ status diagnostics (in-situ) based on studying of laws of aquatic organisms and communities organization levels variability adequately reflect water quality and ecosystem health. New methodical solutions on hydro/chemical information compression to the unified indicator of the impact doze and vindication of informative biological water quality assessment criteria are depicted. Results of practical testing of the developed methods on a number of water bodies of Russia are presented. The methods are based on revealing of the cause-effect relations that are developed on the basis of doze-effect dependencies between the water quality chemical composition integral indicator and fish physiological status indicators.
