This represented the first record of this species in Western Europe and a major westward range extension for this Ponto-Caspian species. Density was very low, with the ratio of Dreissena polymorpha to D. rostriformis bugensis in the order of 100:1. Mean length (n=5) was 22.5mm (range 20.4-24.6mm), suggesting that they were at least twoyears old and that the original introduction into the Hollands Diep had occurred in 2004 or earlier. Species identity was confirmed by morphological and molecular methods. We speculate that the invasion occurred through the Main-Danube Canal - a pathway that is becoming increasingly recognized as a southern corridor for the potential movement of non-indigenous aquatic species between Eastern and Western Europe.
