Brown Bullhead FAQ
Answers from onWater's species guide.
What are the best lures and bait for Brown Bullhead in Wisconsin?
Worms are especially effective. Other productive baits include chicken livers, nightcrawlers, cut bait, minnows, corn, marshmallows, white bread, and dough balls.
What flies work for Brown Bullhead in Wisconsin?
For fly fishing, the Troth Bullhead pattern (created by Al Troth for big browns on the Madison River) works well - tied on #4-10 streamer hooks with peacock herl, black marabou, white bucktail tail, white yarn body, and spun deer hair head, fished heavily weighted along the bottom.
When is the best time to fish for Brown Bullhead in Wisconsin?
The prime fishing season runs from late spring through fall, with spawning periods between April and July (when water reaches 70-77°F) being times to avoid targeting them.
How do you catch Brown Bullhead in Wisconsin?
Present baits on the bottom of shallow bays in the evening. Let fish mouth the bait for several seconds before setting the hook due to their extremely tough mouths. Since bullheads are scavengers that feed primarily by smell, avoid artificial lures and focus on the stinkiest natural baits possible.
What do Brown Bullhead eat?
They're omnivorous bottom feeders with an estimated 100,000 taste receptors distributed across their smooth skin, making them extremely effective at locating food by smell. Their diet includes aquatic plants, algae, insects, worms, fish e.g.gs, small fish, crayfish, snails, and freshwater clams.
