The aim is to develop aquatic environment state indicators for the zones of different transformation of river water in the marine coastal zone. The main observation areas are the ZRWT in the Azov-Black Sea region. Quantitative samples were collected and analyzed – 2341, and 64542 measurements were performed. Regular comprehensive research in the littoral (coastal) zone is essential to assess the ecological status and effective management for aquatic ecosystems. The research are based on the «ecotonic effect» idea in the ZRWT. Earlier, the authors zoning the Danube marine waters according to the zooplankton structural and functional organization. The results of the work make it possible to clearly distinguish between "coastal" and "transit" waters. Quantitative indicators of the state of aquatic organisms in different ZRWT have been established (the main limiting factor is salinity). For different aquatic organisms groups, unstable hydroecological conditions in the transformation zone have different vector of action, which leads to changes in the structure and productivity of the group. New indicators of the state of groups in different types of biotopes have been established. Quantitative values of indicator the aquatic environment state indicators the in the marine coastal zone in different ZRWT have been determined and the hypothesis of the existence of the coastal ecotone at a salinity of 12-17 ‰ has been confirmed. The dependence of the structure and quantitative development of aquatic organisms on the composition of soils is established. Methodological approaches and indicators for hydroecosystems ecological monitoring based on the aquatic organisms state in the marine coastal zone according to the criteria of the EU Water Framework Directive are proposed.
