Saltwater · Year-round; inshore fish move to nearshore reefs in spring, offshore in fall

Gag Grouper

Mycteroperca microlepis

The grey prize of Gulf and southeast ledges — gag grouper rush baits from holes and wrecks and dive straight back, so the first ten feet of the fight are everything. Live baits over ledges in spring and fall produce the biggest fish.

Identifying features

Grey to grey-brown body with dark, worm-like (reticulated) markings along the back and sides
Squared-off, slightly concave tail fin — unusual among groupers
Distinct notch and spine on the cheek (preopercle) that help separate it from black grouper
Forehead profile is concave, giving the head a scooped look
Look-alike: red grouper are reddish-brown with pale blotches and a rounded tail; gag are grey with worm markings and a square tail

Habits

Young fish live in estuaries and grass flats; adults hold tight to ledges, wrecks and rock in 60-200 ft
An ambush feeder that rushes out of a hole, inhales the bait and dives straight back
Feeds on porgies, grunts, sardines and other reef fish
Moves inshore onto nearshore reefs in spring and fall, deeper in summer and winter

How to catch them

Live-baiting ledges and wrecks

Rig: Heavy bottom outfit, 80 lb leader, 7/0-8/0 circle hook, fish-finder rig

Bait/lure: Live pinfish, grunts or porgies

Key tip: Lock the drag and wind hard from the first second — a gag that reaches its hole is usually gone.

Trolling plugs over nearshore rock (fall)

Rig: Large deep-diving plug on a heavy trolling outfit, short wire or heavy mono leader

Bait/lure: Deep-diving plugs in firetiger or natural baitfish colours

Key tip: Troll right along the ledge edge at 4-6 knots. Mark every strike — gag hold on the same rocks all season.
