Covered in slime — keep a towel handy and watch those spines.

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
Good eating when fresh.
- 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
Venomous serrated spines in the dorsal and pectoral fins cause very painful wounds. Step on the fish with a shoe and use pliers.
- Regulations
Check local rules. 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.
