A Minnesota man pleaded guilty on Friday in Fort Frances, Ontario to over-possession of fish, costing him nearly $500 and a chance to register the 52-pound, 3-ounce lake trout as a world record on a tip-up rig. Rob Scott, 65, was checked by two Ontario Ministry of Natural Resources officers earlier in the day when he already had a lake trout on the ice. The daily limit is one. The officers later read a newspaper account of Scott’s possible record and put the pieces together. Scott Anderson in the Mnpls Star-Tribune.
