BigJoe's tip

Fresher bait = more bites. Cut it right before it goes in the water.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Clean & cook

Is it good to eat, and how to prepare it.

Edibility

Excellent eating — one of the best-tasting fish in its range.

Cleaning

Bleed and ice it right away. Fillet, then remove the skin and any dark bloodline.

Cooking suggestions

Cook fish to 145°F (63°C) — the flesh turns opaque and flakes easily. Fry, grill, bake or blacken.

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Stiff, sharp spines in the dorsal and pectoral fins can cause painful wounds.

Regulations

Check FWC/state rules; many states limit large fish. A Florida fishing license is required unless you are exempt; Florida rules are set by FWC (myfwc.com). Federal waters fall under NOAA Fisheries. Other states and countries set their own limits — check before you keep fish.

Conservation

Keep only what you'll eat, release the rest quickly, and follow size and bag limits.
