Ten-year-old Koen Norton of Prince Edward Island performed a he-man landing of a 486-pound (220-kilogram) bluefin tuna over the weekend. It may be a record-breaker too as Koen and his dad wait to hear from the Guinness Book of World Records to find out if it’s the biggest fish ever caught by a 10-year-old using the stand-up fishing technique. Koen spent an hour in a fishing pole harness with the tuna on the end of his line, reeling it in bit by bit, until he and his father were able to bring the fish back to shore.
