Taxonomic Group: Fishes


Brown Bullheads (Ameiurus nebulosus) are native through the interior basins from southwest Saskatchewan to the St. Lawrence estuary in Quebec, and Arkansas to Florida and the tip of Florida to New Brunswick. They have been widely introduced in western North America and to Puerto Rico, 21 European countries, Iran, Turkey, Vietnam, China, and New Zealand. They were introduced as food and sport fish but are potential predator on and competitor with many small native fishes. Few specific negative impacts have been reported, but they have had a negative impact on native fish in British Columbia, Canada.
