Rafael and his crew were using nets to catch bottom-dwellers when they inadvertently snagged the giant tuna. However, federal fishery enforcement agents took control of the behemoth when the boat returned to port. The reason for the seizure was procedural: While Rafael had the appropriate permits, fishermen are only allowed to catch tuna with a rod and reel.

In an interview with the Standard-Times of New Bedford, Rafael disputes the claims from the National Oceanic and Atmospheric Administration's (NOAA)  enforcement division that the humungous tuna was trawled from the bottom of the Atlantic. "They didn't catch that fish on the bottom," he said. "They probably got it in the mid-water when they were setting out and it just got corralled in the net. That only happens once in a blue moon."

And while Rafael is denied the mother of all fish stories, the federal impoundment of his catch also means he's probably losing out on a giant payday. A 754-pound tuna recently sold for nearly $396,000. NOAA regulators do not share any of the proceeds from the fish's eventual sale with a fisherman found in violation of federal rules.
