The non-native populations of both species were in better somatic condition and grew faster. The biomass of nonmollusc macrozoobenthos, dominated by Amphipoda, was markedly higher in the non-native range while molluscs were recorded frequently in both the native and non-native ranges. Amphipods were far the most consumed prey by non-native fish, whereas native fish combined two main prey types - amphipods and fish (bighead goby) and amphipods and bivalves (round goby). Rich food resources utilised by the non-native bighead and round goby contribute to their invasive success in the upper Danube.
