Largest tuna in the world ever caught: Atlantic bluefin record, size, and facts

Atlantic bluefin tuna, the largest tuna species, can reach immense sizes, weighing up to 2,000 pounds. These apex predators inhabit temperate waters and are a significant challenge for anglers. Ken Fraser’s 1979 catch of a 1,496-pound bluefin tuna off Nova Scotia remains the world record, a testament to the fish’s power and the angler’s skill.
