Freshwater polychaetes are the most diverse in the Palaearctic, including the Ponto-Caspian region as
an important area of diversity. One of several polychaete species that are spreading from this area is
Manayunkia caspica. For a certain period of time, the range of this species in the Danube River has
been limited, probably because of the Iron Gate dam. This Ponto-Caspian species, which is established
along the Romanian stretch of the Danube River, was recorded for the first time in the Serbian part of
the river in November 2005, and subsequently, it has been repeatedly found in the Iron Gate II Reservoir
at 934 rkm (the town of Kladovo). During the Joint Danube Survey 3 (JDS 3) in September 2013, it
was observed that M. caspica has extended its distribution from the Ponto-Caspian region to Central
and Western Europe, with Klizska Nema (Slovakia/Hungary) as the most upstream locality. The findings
presented herein show that the distribution of M. caspica has for the first time expanded upstream of the
Iron Gate, where it appeared to have established population, making this species a regular component of the macroinvertebrate fauna along the entire stretch of the Danube River.
