The channel catfish is native to North America — southern Canada, the central and eastern United States and northern Mexico — from clean, well-oxygenated rivers, lakes and reservoirs. It eats fish, crustaceans, molluscs and insects. It is the most fished catfish in the United States and widely farmed for food; it has been introduced to many countries and is considered invasive in many of them. It exceeds 1 metre.
