The regulations impose no statewide size limit but establish a daily bag limit of one flathead catfish and five channel catfish.
New state record tips scales at 50 pounds, 7 ounces.
Mark Mosby caught the fish on the St. Croix River near Stillwater. It measured 52-1/2 inches and had a girth of 32 inches.
Nathan Williams, 30, and his boys Jayce, 14, River, 8, and Phierce, 6, are well-known in the noodling world.
Jake Robinson of Shakopee caught and released the new record flathead catfish May 15 on the Minnesota River near Savage. He caught the 49-inch fish on 100-pound test line. It had a girth of 33-1/2 inches, identical to his previous record caught on June 7, 2016. But because of different markings, they appeared to be two different fish.
