Channel Catfish FAQ

Answers from onWater's species guide.

What are the best lures and bait for Channel Catfish in Wisconsin?

Nothing beats prepared 'stink baits' or 'punch baits' like CJ's Catfish Punch Bait, Sudden Impact Fiber Bait, or Sure Shot Catfish Punch Bait. Channel cats also take strips of fish, nightcrawlers, chicken liver, soap, dough balls, crayfish tails, and artificial lures like spoons, jigs, and plastic worms.

When is the best time to fish for Channel Catfish in Wisconsin?

Late spring through early fall, with summer being peak season. Avoid fishing during spawning (May-July when water hits 75°F) as fish are less active and more protective of nests. They stop feeding in winter, congregating in deep pools in a semi-hibernation state.

How do you catch Channel Catfish in Wisconsin?

Fish the bottom using slip sinker rigs with minimal weight to avoid spooking these light-bite fish. In shallow water under 5 feet, slip bobber rigs work excellently. Cast to structure and let current carry scent to fish.

What do Channel Catfish eat?

They feed on insects, crayfish, small fish, snails, aquatic vegetation, and virtually anything organic. Unlike the exclusively live-fish diet of flatheads, channel cats are primarily scavengers moving along shores feeding on any vegetable or animal matter.

Where do Channel Catfish live in Wisconsin?

Found throughout the state's major river systems including the Mississippi, Wisconsin, Fox, and St. Croix rivers, plus Lake Winnebago and Green Bay tributaries.
