Common carp Cyprinus carpio possess multiple traits that contribute to their success as an invasivespecies. They have been introduced across the globe, and abundant populations can have numerousnegative effects. Although ecological niche-based modelling techniques have been used to predict thepotential range of C. carpio invasion in U.S.A., occurrence and abundance patterns have not yet beenconsidered on a regional scale. In the present review new locations are documented, the status of thesouthernmost population has been studied and the probability of new lakes and reservoirs being colo-nized by C. carpio has been obtained and related to environmental conditions. The new localities forC. carpio have expanded its distribution westward, into the Andean Region, and present results fromthe South American southernmost population have shown a well-established population. Analysis ofpresence data provided two principal results: (1) the probability of a site being with C. carpio can beinferred using environmental variables and (2) the probability of a site being with C. carpio is a use-ful tool for the prediction of future invasions. Selective fishing on the Negro basin could constitute apotential mitigation measure, decreasing the abundance of the species and thus reducing the species?potential for southward expansion. These results reinforce the idea that artisanal fisheries, food produc-tion and conservation interests should be taken into account by local government management agenciesin any discussion regarding the southern distribution of C. carpio in the near future.
