Bivalves are considered the key species in aquatic ecosystems, being capable of controlling and transforming their structure and functioning through their filtering activity. Freshwater bivalve invasions are nowadays a global phenomenon, which began to take on the increase. Sinanodonta woodiana is the most widespread species of the family Unionidae out of her natural distribution range. Originally from East and Southeast Asia, it has rapidly spread in Europe and later on in the other parts of the world, firstly with fish species used on fish farms. Just out of these fish farms, the species has migrated into the Danube and its tributaries, the Sava and the Drava, and then in their tributaries, where it has established a stable population able to reproduce. S. woodiana has predispositions to be a successful competitor of indigenous species in Europe as well as in other continents. These predispositions include a non-selective strategy in using its hosts during the parasitic stage and being able to reproduce successfully in suboptimal environmental conditions. For all those reasons, S. woodiana is a potential threat to native habitats and communities, but also the whole ecosystem and economy.
