Bigmouth Buffalo

Body Type & Identification: Bigmouth Buffalo is a member of the sucker family (Catostomidae) — characterized by a downturned, fleshy lips adapted for vacuuming invertebrates and algae from the stream bottom. Can reach 70+ lbs — the largest sucker species in North America. Bronze to olive-gray body. A long-lived species — individuals verified to exceed 110 years old. Trophy Buffalo fishing is a niche but growing sport

Preferred Water Temperature: 55°F–70°F. A cool to warm-water bottom species most common in clear, clean rivers and streams. Suckers spawn in spring over gravel and rocky riffles — spawning runs can be spectacular and are an important early season food source for eagles and other predators.

Habitat: Found throughout the Mississippi River drainage from the Great Lakes south to the Gulf — one of the largest members of the sucker family. Found in large rivers, lakes, and reservoirs with slow current over muddy or sandy bottom. A semi-filter feeder — uses the large, terminal mouth to consume plankton and soft invertebrates from the water column as well as the bottom An important prey species for larger predators including Muskellunge, Northern Pike, and Striped Bass — large suckers are outstanding live bait.

Best Lures: Rarely taken on artificial lures. Occasionally caught on small jigs bounced near the bottom.

Best Baits: Nightcrawlers are the top bait. Small worm pieces work well. Fresh crayfish tails produce results. Small pieces of clam are effective. Light to medium bottom rigs with natural bait near current breaks in clear rivers.

Top 5 Destinations: Found throughout their respective river systems — suckers are widespread but seldom destination-fished. Spring spawning runs in clear Midwest and eastern rivers attract significant angler interest.
