AB  - The co-existential pattern of native and alien species was investigated along the Danube River Basin (DRB) during JDS4 (2019). A total of 51 JDS4 sites was sampled in the entire Danube River, and additional sites in the Lower Danube. The standard operational procedures adopted by ICPDR, and – for the first time – eDNA-based tools were used for the sampling. A smartphone application ‘Invasive Alien Species in Europe’ developed by the European Commission’s Joint Research Centre and specifically updated to include invasive alien species concerning the DRB was additionally applied for data collection.
Six alien aquatic plants, 35 benthic macroinvertebrates and 17 fish species were recorded in DRB during the survey. Two groups of invasive species should be mentioned: 1) Ponto-Caspian species that do not have to cross very strong hydro- and geographical barriers during their spreading; and 2) Species that cross large geographical distances to arrive to the DRB (originated from North America and Asia). An overall decrease of the former abundance of Corbicula fluminea was recognised in some Danube sections. An extreme large amount of Ponto-Caspian amphipods was detected in the Upper Danube: Echinogammarus sp. and Gammaridae gen. sp., representing one third of the overall individual number of the macroinvertebrates detected in the Upper Danube (Austria). New Decapoda species (Procambarus clarkii, Pacifastacus leniusculus) appeared at new locations of the Middle Danube, indicating their recent spreading. A new Ponto-Caspian snail species (Clathrocaspia knipowitschii) was distributed along extended sections of the Lower and Middle Danube. The magnificent bryozoan Pectinatella magnifica was recorded for the first time in the Bulgarian shoreline zone of the Danube River. The (e)DNA-based detection revealed the presence of 5 macroinvertebrate species which were not recorded by other methods. The level of biocontamination of the Danube River was estimated as moderate to high, with higher levels for the Upper (high to severe biocontamination) and Middle
41
Danube (moderate to high biocontamination), in comparison to the Lower Danube (low biocontamination). The results show that DRB is under considerable influence of biological invasions. The number of identified alien species has increased over three times since 2007. The (e)DNA-based method has proved to be an effective additional tool in aquatic IAS monitoring. The smartphone app may greatly facilitate the access and update of IAS records for management and control purposes and contribute to IAS awareness raising in the Danube countries by involving actively the citizens in future surveys.

AB  - Aquatic ecosystems are exposed to the influence of non-indigenous (non-native, alien or exotic)
species. The Danube River is not an exception. Non-indigenous species were recorded among algae,
aquatic macrophytes, macroinvertebrates and fish. Also, introduction of allochthonous fish species
caused introduction of new fish parasites (Djikanovic et al. 2012).
The pressure caused by biological invasions has already been documented for the Danube River and
its main tributaries (Literáthy et al. 2002, Csányi 2002, Csányi & Paunović 2006, Liška et al. 2008).
The Danube River is a part of the Southern Invasive Corridor (Panov et al. 2009). The Southern
Corridor links the Black Sea with the North Sea basin via the Danube-Main-Rhine waterway including
the Main-Danube Canal. Thus, the Danube River is a part of one of the main routes for the migration
of aquatic organisms in Europe, including the non-native species and consequently the river is exposed
to high potential pressure from biological invasions.
The aim of this chapter is to present the state of the art in respect to presence of non-native aquatic
species (aquatic macrophytes, aquatic macroinvertebrates and fish) in the Danube River based on Joint
Danube Survey 3 (JDS3) results. Also, the present situation is compared with prior, based on previous
Danube Surveys.
