Weighing in at 327 pounds, the nearly 8½-foot-long prehistoric-looking creature has a girth of 47.95 inches, WAPT.com reports.
"At first I didn't think he was that big. But as I was getting him into the boat, it was like, 'How big is this thing?'" said Kenny Williams of the fish he angled in Mississippi's Chotard Lake.
"It was a lot of effort just to get him into the boat," he added, saying that after he netted the fish, he grabbed it by the gills and hauled it in.
An alligator gar is a fish with a long, heavily scaled body and an elongated snout containing rows of sharp teeth.
The Mississippi Department of Wildlife, Fisheries and Parks speculates that this may be the largest alligator gar ever caught, besting a 302-pound gar reportedly found in 1963. So far, the current record holder, according to the International Game Fish Association, goes to a 279-pound gar caught in Texas in 1951.
Williams has donated his catch of the day to the Mississippi Museum of Natural in Jackson, where it will be mounted for a permanent display.
