2020 (12) - Pages 185-188In recent years, Asian clams and especially Corbicula species (C. fluminea (O. F. Müller, 1774) and C. fluminalis (O. F. Müller, 1774)) have widely and rapidly colonized several large river basins in France (Loire, Garonne, Rhône) and in Europe, as in other loci of introduction. In 2018, malacological study of collections of Clermont Auvergne University by the team of the Museum Henri-Lecoq (Clermont Auvergne Métropole) allowed to identify Asian clams among specimens of shellfish coming from various basins of Western Europe. They were dated from the late nineteenth century, when Asian clams introduction was considered much more recent. The interest of studying naturalist collections in understanding the dynamics of introduced species is thus confirmed.
