Abstract
The golden mussel (Limnoperna fortunei, Mytilidae) is native to continental China, but is emerging as an important invasive species. It was first recorded in South America in 1991 in the estuary of the Rio de La Plata and dispersed into the largest rivers systems of the Plata basin (Rio de la Plata, Rio Paraná, Rio Uruguay and Rio Paraguay), travelling inland at an estimated rate of 240 km per year.1
