As the old aluminum boat slid through the shallows of a marshy lagoon near North Topsail Beach, N.C., Capt. Alan Jernigan didn’t see the fish at first. Sure, it was black dark, but it still seemed odd to see a flounder that was almost as big around as the generator on the floor of his boat that was pumping power to the underwater lights. The eyes gave it away. When Jernigan saw those bulging peepers, he backed up on the beast and thrust downward with his gig. The water erupted. He’d never seen a flounder this big or had anything this powerful on the end of his trident. He was so nervous about losing the fish, he jumped into the water and held it pinned to the bottom for 10 minutes before bear-hugging it into the boat. This flounder, his biggest ever, weighed 16 pounds and measured 32 inches long.
