摘要:Dreissena polymorpha (zebra mussel) has been invading freshwater bodies in Europe since the beginning of the 19th century and is still doing so. The zebra mussel was introduced in the Iberian Peninsula in 2001, and since then the Ebro Hydrographic Confederation has adopted several measures to stop the invasion. The main invasion route for the zebra mussel in Spain is via recreational boating in lakes and reservoirs, so the main measure adopted has been to change the navigation rules in the Ebro basin. Restrictions on the number of navigable reservoirs and the introduction of disinfection protocols and access controls have helped to prevent the spread of the zebra mussel.
