Découverte de Sinanodonta woodiana (Lea, 1834) (Bivalvia : Unionacea) dans un réservoir eutrophe : le Grand Large en amont de Lyon (Rh ne, France)

The Chinese pond mussel Sinanodonta woodiana was recorded for the first time from a fish hatchery near Arles (Southern France). It has recently been found in a eutrophic reservoir, le Grand Large upstream from Lyon where it is associated with the other alien species Corbicula fluminea and Dreissena polymorpha.
