The article presents monitoring of the course and the
beginning of new invasions due to the intensification
of these processes in the basin of the Azov Sea of;
investigation of the influence of the alien species
upon the acceptor ecosystem. Methods. The material
was collected at the monitoring transect in the Don
River delta and in the surveys of the r/v “Professor
Panov” in the Taganrog Bay, Sea of Azov. Standard
hydrobiological methods of the data collection were
used. Results. Penetration of three polychaete species
was recorded; course of invasion of two of them was
traced. Impact upon the acceptor ecosystem was
researched. Preliminary species identifications using
morphological characters were carried out; sources
and the ways of the invasions are suggested.
Conclusions. Estuary zone of the Sea of Azov (the
Taganrog Bay) has a high invasion capacity. Of the
three species penetrated into the Sea of Azov basin in
2013-2015, one (Aracia sp.) naturalized successfully,
though didn’t affect much the ecosystem. On the
contrary, polychaetes of the genus Marenzelleria are
increasing rapidly their area; in two years, they
became dominant along the considerable part of the
water body. The invasion of Streblospio sp. is at its
very beginning at the time
