The purpose of the work is to assess and diagnose the state of biocenoses and biodiversity of marine ecosystems. Research methods - studies of aquatic organisms at the population (biocoenotic) level, during which the state of planktonic and benthic groups of marine ecosystems was registered. The report presents the results of observations on the hydrobiological component of the marine ecosystems of the seas of Ukraine in 2019, the ecological criteria and species-indicators assessed the state of biota. Structural changes in groups of aquatic organisms are noted and their condition is determined. Modeling of processes of influence of extracted pollutants of bottom sediments of the marine environment in laboratory conditions on the population of microalgae is carried out. The active development of coccolithophorids, namely Emiliania huxleyi, as well as noctiluca scintillans indicate an increased level of eutrophication and indicate an unstable ecological situation in the studied areas in the summer. Appendix A presents a map - a scheme of research stations in the north - western part of the Black Sea, Appendices - B, C lists the registered species of phytoplankton, macrozoobenthos, Annex D lists the publications on the topic.
