    <dcterms:abstract xml:lang="eng">Fish assemblages in the Neckar River were investigated by electrofishing under the Water Framework Directive 2000/60/EC(WFD) to assess the ecological status of rivers. This monitoring program also provides information on the distributionof invasive Ponto-Caspian gobies along the Neckar River in Germany, a tributary of the Rhine River. The western tubenosegoby Proterorhinus semilunaris was first recorded on the Neckar River in 2007, followed by bighead goby Ponticola kessleri and round goby Neogobius melanostomus in 2009 and 2012, respectively. The currentdistribution boundary for Ponto-Caspian gobies coincides with the navigation limit for cargo ships at the river portof Plochingen (about 200 km up­stream of the city of Mannheim). Marked differences in fish assemblages took placefollowing invasion of the round goby, with average CPUE of native stone loach Barbatula barbatula andgudgeon Gobio gobio declining from 19.6 and 21.5 individuals per 100 m, respectively, to fewer than one.Bighead gobies failed to build up a stable stock after round goby invasion but have still been caught in small numbersat most sampling sections. The earlier-arriving western tubenose goby could not be detected any longer. The resultsindicate a strong impact of the round goby on native fish assemblages in the Neckar River which will hamper effortsto improve the ecological quality of the river. Further investigations are needed to assess long term effectsof round goby invasion and find solutions for achieving the mandatory European Water Framework Directive (WFD)target of “good ecological status” of the river.</dcterms:abstract>
