Jon Black landed what is likely the biggest goliath grouper ever caught from a kayak—an estimated 552 pounds, reports GRIND TV.

Black, who works at Crazy Lure Tackle shop in Cape Coral, Florida, was fishing off Sanibel when he hooked into the giant grouper. When he finally brought the behemoth to the surface, he let out a celebratory holler “like a little kid catching his first fish,” reports Dave Strege of GRIND TV.

During the fight, the The massive fish snapped his rod in half. Even with a broken rod, Black still managed to get the massive bottomfish to his kayak. The fish was measured and then released, as is required by law since the goliath grouper is a protected species.

The fish measured 83 inches long with a 73-inch girth. Using those measurements, the goliath grouper’s weight was estimated at a cool 552 pounds. Strege notes that while no official kayak fishing records are kept, Black’s goliath is almost certainly a record kayak catch. The all-tackle world record for the species is 680 pounds, caught off Florida way back in 1961, before they became protected.
