Resum

The asp Leuciscus aspius (L. ), a large piscivorous cyprinid fish, is reported for the first time in the Iberian Peninsula. Six individuals were captured in July 2017 and many other were observed in the Darnius-Boadella Reservoir (Muga river basin, NE Spain). Our observations suggest that the asp has established in the reservoir, representing a potential threat to the native species of the Muga River. As it has been the case with several other alien fish species, the asp is likely to be illegally spread to other Iberian river basins if current management measures do not change.
