A moving tide — especially the last of the outgoing and first of the incoming — is best.

Catch it
Step by step, from first cast to landing.
Step-by-step: how to catch it
- Go where it lives: Muddy and sandy bottoms in bays, creek mouths, docks and rivers — it can go into nearly fresh water.
- Rig up: 7 ft medium-light to medium spinning rod with a 2500–3000 reel. 20–30 lb fluorocarbon, 2–3 ft.
- Pick your bait: Live mud minnows, finger mullet and shrimp. Lures: Soft plastics on a jig head dragged slowly on the bottom; Gulp! swimming mullet.
- Fish it: Drag baits slowly along drop-offs, creek mouths and dock edges; give the fish a moment before setting the hook.
- Time it: Dawn, dusk and the first hours of a moving tide are the best windows. A moving tide — especially the last of the outgoing and first of the incoming — is best.
- Fishing techniques
Drag baits slowly along drop-offs, creek mouths and dock edges; give the fish a moment before setting the hook.
- BigJoe's tip
Flounder lie buried and ambush — a slow drag along the bottom beats a fast retrieve.
- 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
Watch the sharp gill covers and dorsal spines; use a lip gripper or wet hands.
- Regulations
Florida has a flounder size limit, bag limit and a fall closure for harvest; other states set their own. 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.
