The quaggamussel Dreissena rostriformis bugensis was first discovered in the Netherlands in the Rhine (Hollands Diep) near Willemstad in 2006. Based on the size of the specimens it was concluded that the species became established in 2004 or earlier. Subsequent studies showed that the specimens probably colonized the Rhine through the Rhine-Main-Danube channel. Since then the quaggamussel became a common species in the Netherlands. Clearly, the species is quickly spreading and increasing. The species has a lot of potential to become a prominent bivalve in the Dutch aquatic ecosystem besides (or in place of) the earlier introduced zebra mussel Dreissena polymorpha.
