But on December 4, angler Mark Carlson of Rockford, Illinois, hooked into a massive 52 inch / 132 cm musky and estimated at 55 lb - 24.95 kg.
The big fish put up a brutal 15 minute fight after it crushed the Legend Perch lure he was trolling on the St. Lawrence. Carlson, the current I.G.F.A. "All-Tackle Length Record" holder for musky, immediately realized his catch was of record quality and quickly measured, photographed, and released the fish alive.
The potential record catch was also equipped with a tag before it was released, as Carlson actively participates in a Quebec fisheries study.
