Tuna possess incredible power and speed in the water. Species like bluefin tuna can reach sizes over1500 pounds and can accelerate to over 40 mph in a burst. Their compact torpedo-shaped bodies andlunate tails provide extreme hydrodynamic efficiency that lets them chase down prey at high speeds.

Their power manifests in the strength of their strikes and runs when hooked. “From head to toe, bluefintuna are nothing but muscle,” says Captain Joe Shute, who targets them off North Carolina. “I’ve seen abluefin kick a big guy’s ass in 15 minutes.” Their strength is such that anglers use heavy stand-up harnessesto fight them. “You have to make the fish earn every inch,” Shute says. “If you try to fight them they’ll killyou.”

The tuna struck Quatro relentlessly, tearing chunks of flesh from his back andlegs. Bite marks covered his body as he struggled to escape.

While free swimming tuna only attack people on very rare occasions, captured tuna pose a serious threat toanglers trying to land them. Tales of tuna enacted retribution on captors are commonplace. As one bluefintuna captain relates: “They flat-out tear stuff up. I’ve seen them throw coolers, break fishbox lids, jump off thegaff, we even had one fish smack an angler in the chin and knock him over.”

More frightening are the flesh wounds that can result when they get their teeth into human limbs. Storiesabound of tuna biting fingers down to the bone. The most vicious payback comes when tuna use theirfinal moments to make a last ditch attempt at freedom. “I’ve seen a bluefin kick a big guy’s ass in 15minutes,” says Shute.

The power of tuna is so great that it takes proper equipment and technique just to land them withoutinjury. Harnesses take the brunt of the pulls allowing anglers to slowly tire them out. Multiple heavy gaffs wasthem into submission. Only then can tuna be subdued and anglers avoid becoming another victim.

to rapidly bleed out. There are likely unreported instances of tuna killing swimmers throughout history.

However, modern accounts of tuna inflicted deaths appear scarce possibly due to the rarity of suchinteractions. Regardless, tuna should always be treated with caution and respect by anglers. While actualdeaths might be uncommon, their strength and teeth pose a clear danger if proper precautions aren’t taken.As Shute aptly surmises, “If you try to fight them they’ll kill you.” Any angler who has done battle with atuna and lived to tell the tale surely knows there is truth to this statement.
