A survey of species belonging to the family Mysidae, conducted in June 2007 in fresh- to brackish waters of eastern France, revealed a recent range extension of the invasive Ponto-Caspian species Hemimysis anomala to the Moselle, Saône, and Rhône rivers. In the estuary of the Grande Rhône it reached for the first time the coast of the Mediterranean Sea. The network of navigation canals in NE France was likely a key element of its north to south pathway starting from the Rhine River. Important range extensions were also noted for Limnomysis benedeni in this network and in the Moselle River. The euryhaline species Neomysis integer, endemic in coastal waters of the NE Atlantic, was found in the brackish reach of the Canal-d’Arles-à-Fos in the Rhône delta. This finding confirms the very rare records from the 1930-50s along the Mediterranean coast of France. Potential effects at the ecosystem level, invasion mechanisms, and the potential further expansion of the three mysid species are discussed.
