How to Rig for Gag Grouper

Mycteroperca microlepis

Gag grouper live on rocky ledges, reefs, and wrecks in the Gulf and South Atlantic, and bolt straight back into the rocks the moment they are hooked. Heavy tackle and a locked-down drag are needed to turn them before they hole up. Live bait on a circle hook is the most reliable approach, and cooler months often bring fish shallower.

The sinker slides freely on the main line, so a fish can pick up bait and move off without feeling resistance. Good in heavier surf or current where a fixed weight would spook a bite.
