Investigation of allochthonous macroinvertebrates and fish species of the
Danube River was based on samples collected during August and September 2007 and
2013. Detailed overview of allochthonous species was presented regarding: taxonomic
and zoogeographic analyses, testing of indices and risk assessment procedure and
invasiveness of the area, as well as correlation of the level of biological invasions and
selected parameters of pressures. Further steps for reduction of new invasions,
spreading already established allochthonous species and reduction of pressures were
pointed separately.
In total, 31 allochthonous macroinvertebrate species were registered. The most
numerous were Crustaceans – group Malacostraca, originate from Ponto-caspian region.
Among fish, 11 allochthonous species were detected from three different biogeographic
region: Ponto-caspian, North American and Asian.
Regarding the mode of arrival and pathway we may conclude that the large
majority of non-indigenous fish species and only few macroinvertebrate species were
introduced as a direct effect of human intervention.
Analysis of allochthonous fauna showed that Upper and Middle sectors of the
Danube are most affected. Due to high potential to spread, high potential for
establishment in new environment and high potential to cause ecological and negative
socio-economic impacts, eight macroinvertebrate and seven fish species were specified
as Black list alien species.
For seven macroinvertebrate and three fish species high level of Biological
contamination Index was estimated: Chelicorophium curvispinum, Corbicula fluminea,
Dikerogammarus villosus, Dreissena polymorpha, Dreissena bugensis, Pectinatella
magnifica, Sinanodonta woodiana, Carassius gibelio, Lepomis gibosus i Neogobius
melanostomus.
Based on the overall analyses of selected parameters assumed that are important
for intensity of biological invasions, we may conclude that part of the Danube stretch
between Belgrade and Iron Gate I dam, as well as locality downstream Novi Sad are
most affected regarding biological contamination. High class of invisibility was
determined due to high intensity of water transport, as well as the level of
hydromorphological changes.
Activites regarding invasive species recommended in this thesis are: definition
of effective national legislation, creation of the National list of allochthonous species,
assessment of their invasiveness, list of indicators of current status of selected water
bodies, to increase public awareness about invasive species.
