The paper reviews the results of monitoring of aquatic vegetation of the Kuyalnitsky Liman in the period 2015–2018, when launched into the ecosystem of sea water from the coastal zone of Odessa Bay. As a result of the monthly monitoring, the patterns of formation of phytoperiphyton communities in the liman on the newly created biotopes of the water guide trays of the connecting channel Black Sea – Kuyalnitsky Liman are presented. Based on the morphofunctional indicators of phytoperiphyton, assessment of the categories of Ecological Status Class (ESC) according to requirement of the EU Maritime Strategy is given.During the studied period, it was shown that 29 species of macroalgae and microalgae belonging to the divisions of Chlorophyta, Ochrophyta, Rhodophyta, Bacillariophyta entered with sea water to the Kuyalnitsky Liman from coastal zone. At the same time, the mass development of marine algae was not observed in the liman, since the salinity did not decrease less than 165 ‰. Under the influence of seawater flows on the trays of the connecting channel, the Black Sea – Kuyalnitsky Liman formed communities of phytoperiphyton with two species of green filamentous macrophytes and four species of diatom algae dominant species.It is shown that the absolute intensity of the functioning of phytoperiphyton communities depends on the fluctuation of the complex of interannual conditions which are connected with autotrophic processes. The maximum intensity of functioning of the “basiphytе-epiphyte” algaesystem was recorded for the spring period of 2017. The contribution to the autotrophic process of the basiphytic and epiphytic components community, was characterized by successive stages. From 2015 to 2018 the contribution of the epiphytic component to the production processes of the algaesystem increased from 5 to 64 (%), while the basiphytic component, decreased from 95 to 36 (%), this indicates the consistent increase of the ecological activity of the phytoperiphyton communities developing on the new biotopes of the Kuyalnitsky Liman.
