Representatives of the [[genus]] ''[[Ictalurus]]'' have been [[introduced species|introduced]] into European waters in the hope of obtaining a sporting and food resource, but the European stock of American catfishes has not achieved the dimensions of these fish in their native waters and have only increased the ecological pressure on native European [[fauna]]. [[Walking catfish]] have also been introduced in the freshwater areas of Florida, with the voracious catfish becoming a major alien pest there. [[Flathead catfish]], ''Pylodictis olivaris'', is also a North American pest on Atlantic slope drainages.<ref name=tol/> ''[[Pterygoplichthys]]'' species, released by aquarium fishkeepers, have also established [[feral]] populations in many warm waters around the world.<ref>{{cite journal|title=The South American Suckermouth Armored Catfish, ''Pterygoplichthys anisitsi'' (Pisces: Loricaridae), in Texas, with Comments on Foreign Fish Introductions in the American Southwest|first=Leo G.|last=Nico|author2=Martin, R.
