[EN] The scarce information on the freshwater bivalve diversity of La Rioja province is reviewed. At least six species belonging to three different families are present: Margaritiferidae (Margaritifera auricularia), Unionidae (Anodonta cygnea, Potomida littoralis and Unio mancus) and Sphaeriidae (Pisidium casertanum and Pisidium personatum). New prospections must be done in order to know the real diversity of this group in La Rioja province. Control measures are also recommended to prevent the invasion of the exotic bivalves Corbicula fluminea and Dreissena polymorpha.
