Abstract

The common carp (Cyprinus carpio) is listed as one of the world's worst invasive species and expensive control programs are undertaken against this freshwater fish species in various regions where it was introduced, including North America. A thorough review of the relevant scientific literature has revealed that at least some of the anti-common carp information and claims made on the IUCN's 100 of the world's worst invasive species website may be somewhat controversial and open to legitimate scientific debate. We analyzed the information presented about the common carp and a few other species, such as purple loosestrife, on this website to determine if such information is both reasonably accurate, up to date, and comprehensive. We argue that the impact of some of these species, including the common carp, can be quite complex, and these species often have a variety of impacts on ecosystems - some positive and some negative - depending on our main focus and interests. Therefore, focusing only or primarily on the negative aspects can be detrimental not only to the targeted species but also to a more thorough understanding of the ecosystems where such species are found.
