Ictalurus punctatus
Taxonomic Group: Fishes


Channel Catfish (Ictalurus punctatus) are native to the Great Lakes-St. Lawrence, and Mississippi-Gulf drainages, from south Quebec and Manitoba and Montana, south to Florida-Texas, including a small part of the Arctic drainage. They are an important sport and commercial fish throughout most of their introduced range. Due to their popularity on the dinner plate, they have been introduced to 28 states, Puerto Rico, and at least 38 countries worldwide, including nine European countries. They have had a positive economic impact as a successful commercial fish, but their ecological impacts are difficult to determine because they are part of a suite of widely introduced freshwater predatory fish that as a group have impacted native fish.
