The channel catfish is one of the most popular sport and farmed fish in North America, recognised by barbels ('whiskers'), smooth scaleless skin, and a forked tail. Native to central and eastern rivers and lakes, it grows to 10–25 kg (22–55 lb), tastes mild, and uses taste buds across its body to find food.
