How to Rig for Blue Catfish

Ictalurus furcatus

Blue catfish are the largest catfish in North America and roam big rivers and reservoirs following schools of shad. Fresh cut shad or herring on a circle hook is the standard bait, fished on channel ledges, humps, and below dams. Big blues often bite best in the cold months, and circle hooks let the fish hook itself as it swims off.
