We review the invasive fish species introduced to Catalonia (Spain) and their mechanisms of ecological impact. Catalonia has about 15 established foreign fish species along with many others that have been translocated. These fish species, which are identical to those that have been introduced worldwide (thereby contributing to biotic homogenization), include: common carp (Cyprinus carpio), largemouth bass (Micropterus salmoides), eastern mosquitofish (Gambusia holbrooki) and many European cyprinids that are not native to the Iberian Peninsula. There are some well-documented repercussions to the native fauna, such as the impact of mosquitofish on endangered, endemic cyprinodonts. The illegal introduction by anglers continues to be one of the main culprits of this environmental problem, one that has been barely addressed by local and state authorities
