Flounder Fishing
A flatfish that buries in the sand, ambushes upward, and rewards a bait dragged slowly across the bottom.
Flounder do one thing: lie on the bottom, half buried, and wait for something to swim overhead. Every effective flounder technique is built around that.
They hold on the sand-to-structure edge — the lip of a channel, the base of a jetty, the down-current side of a bar — and they feed on moving tide when bait is being swept past them.
The fall run is the event. As water cools, flounder migrate from back bays out through the inlets to offshore spawning grounds, and they concentrate at those inlets in numbers.

01
Where to catch flounder
Flounder are inshore fish that stack at pinch points. These are the places worth planning a trip around.
| Water & region | Why it's worth your time | Access & license |
|---|---|---|
| Texas coastal passes | Concentrated fall run through the passes | TX license plus saltwater stamp; November restrictions |
| North Carolina inlets | Strong fall migration fishery | NC coastal license; very short seasons in recent years |
| New Jersey and Delaware Bay | Summer flounder (fluke) drifting | State license/registry; size limits are large |
| Long Island and Montauk | Nearshore fluke drifting over sand | NY marine registry |
| Louisiana and Mississippi marsh | Southern flounder along marsh drains | State saltwater license |
02
How to catch flounder: the repeatable method
Drag a bait slowly along the bottom, on the tide, at the edge where sand meets structure.
- 1Fish moving tide at an inlet, channel edge, bridge, or drain — flounder set up facing into the current.
- 2Drift or slowly work the boat along the sand edge in 8–30 feet, keeping the bait in contact with bottom the entire time.
- 3Rig a bucktail or jig head tipped with a strip of squid, a mullet strip, or a live mud minnow.
- 4Alternatively, use a fluke rig: a bank sinker, a swivel, and a two-foot leader with a live minnow or a Gulp swimming mullet.
- 5Drag and lift — a slow, deliberate bounce along the bottom, never a fast swim.
- 6When you feel weight, drop the rod tip and give the fish two or three seconds to turn the bait before setting.
- 7Set with a steady sweep; flounder are boney-mouthed and a snap set pulls the bait away.
- 8Net every fish. Flounder come off at the surface constantly if you try to lift them.
03
Where flounder hold: the water to fish
Flounder lie buried on the bottom facing into current, waiting for bait to pass. You are fishing the bottom, always, and the ambush edge.
Inlet mouths
Tide
Flounder stack at the mouths on moving tide, especially the last hours of the outgoing.
Structure ambush points
Docks/jetties
The sand pocket beside a piling, jetty rock, or bridge abutment holds a fish almost every time.
Sandbars and troughs
Surf
The cut through a bar in the surf funnels bait and holds flatfish on both sides.
Nearshore reefs
Fall run
Migrating fish stage on nearshore hard bottom before moving offshore in late fall.
04
Best lures and baits for flounder
These are the presentations that consistently produce flounder, with the conditions each one is actually for — not a tackle-shop wall.
Live mud minnow or finger mullet
Best bait
On a Carolina rig with a 2/0–4/0 hook, dragged slowly along the bottom.
Bucktail + Gulp swimming mullet
Lure choice
The most consistent artificial flounder combination anywhere on the coast.
Carolina rig with strip bait
Drifting
A squid or belly strip drifted with the tide along a channel edge covers ground.
Jigging with a soft plastic
Structure
Vertical hops right against a piling or rock where the fish is lying.
Flounder rig with spinner blade
Surf
The blade adds flash and vibration in stirred-up surf where visibility is short.
05
Flounder season by season
Flounder migrate offshore to spawn in fall and return inshore in spring. The fall run is the event.
| Season | Where the fish are | What works |
|---|---|---|
| Spring | Moving inshore into bays, creeks, and estuaries as water warms into the 60s | Live minnows and mud minnows on a Carolina rig along channel edges |
| Summer | Spread through bays: sandy edges, docks, jetties, oyster bars, and inlet drop-offs | Drifting live bait, bucktail with a Gulp trailer bounced along the bottom |
| Fall run | Concentrating in inlets and channels as they head offshore; the heaviest fish of the year | Bucktails and live bait fished in the inlet on the falling tide; gigging on the flats at night |
| Winter | Offshore on the continental shelf spawning; inshore fishing largely over | Closed season in most states; check regulations |
06
Best time of day for flounder
Flounder are ambush feeders that key on current delivering bait past them.
Moving tide
Key
Flounder bury facing the current and eat what drifts by. Fish the last half of the falling tide in inlets and drains.
Daylight
Sight feeders; they bite well through the day in clear water.
Night (gigging)
Where legal, gigging shallow sand flats with lights at night on calm, clear water is highly effective.
07
Rigs that catch flounder
Keep the bait on the bottom and give the fish time.
Carolina / fish-finder rig
1/2–1 oz egg sinker, bead, swivel, 18–24 in of 20 lb fluoro to a 1/0–2/0 kahle hook with a live mud minnow or finger mullet. Drift or slow-troll along bottom.
Bucktail + Gulp
1/2–1 oz bucktail with a 4 in Gulp swimming mullet, hopped along the bottom in inlets; the modern flounder standard.
Double-hook flounder rig
Two dropper hooks with a strip of squid and a minnow on each, fished on the bottom from a pier or boat.
Jighead + soft plastic
1/4–3/8 oz with a paddle tail dragged along sandy drop-offs and dock edges.
08
Live and natural baits for flounder
Live small baitfish, or a strip that flutters.
Mud minnow (killifish)
#1
Nearly indestructible and lively; hooked through the lips on a kahle hook.
Finger mullet
The fall run bait; hooked through the lips and drifted through the inlet.
Live shrimp
Effective but gets eaten by everything else too.
Squid strip / cut bait
As a scent addition behind a minnow or on a bucktail.
09
Flounder strategies that make the difference
Cover ground slowly along the right edges.
- 1Drift, don't anchor. Flounder are spread along sand and shell edges; a slow drift with the current finds them.
- 2Fish the edges: where sand meets grass, where a channel drops off a flat, and the down-current side of a jetty or dock.
- 3Give the fish a two-count. A flounder grabs the bait and turns it before swallowing; setting immediately pulls it away. With circle hooks just reel steadily.
- 4Keep the bait touching bottom the entire time; a flounder will not chase up in the water column.
- 5Use a long-handled net and net head-first — flounder come off the hook at the boat constantly.
- 6In the fall run, camp on the inlet during the outgoing tide; every flounder in the bay eventually passes through.
10
Licenses, stamps, and limits
Flounder are among the most restricted inshore fish right now; several states have cut seasons dramatically.
- 1Buy the state saltwater license or registry.
- 2Check the season carefully — some states now open flounder for only a few weeks a year.
- 3Confirm the minimum size; 15 to 18 inches is typical and it varies a lot by state.
- 4Note the daily bag, often one to four fish.
- 5Check gigging rules separately if you plan to fish at night with lights.
11
What the fishing is actually like
Flounder fishing is patient bottom work punctuated by the most subtle bite in inshore fishing — often just added weight.
The fall inlet run is the exception: fast, concentrated, and often shared with a crowd of boats working the same edge.
Gigging at night, where legal, is a completely different and very effective way to hunt them in shallow water.
12
Gear that decides the outcome
The rod, line, and terminal choices that actually change your hookup rate — with the numbers, not vague categories.
7' medium spinning or casting rod
Core rod
Sensitive tip for the soft bite, backbone to sweep-set.
20 lb braid to 25 lb fluorocarbon leader
Feel is everything; braid transmits the light take.
Bucktail jig, 1/2–2 oz
Best bait
Tipped with squid or a Gulp trailer, it out-fishes most rigs.
Fluke rig with bank sinker
The simple, effective drift rig for live minnows and strip baits.
Live mud minnows or finger mullet
The best natural bait; keep them lively in an aerated bucket.
Wide-mouth landing net
Essential
Flounder shake free at the boat more than any other inshore fish.
13
How to land, harvest, and bleed flounder
What happens between the hookset and the cooler decides whether you land the fish and whether it is worth eating.
- 1Flounder mouth a bait before they take it. Drop the rod tip, count several seconds, then come tight with a slow sweep rather than a snap set.
- 2Always net a flounder at the boat or gaff a keeper. They shake at the surface and come off constantly.
- 3Decide keep or release before you unhook. A flounder you intend to release should never leave the water for more than the length of one held breath.
- 4For release: support the belly, keep the fish horizontal, back the hook out with pliers, and hold it into the current until it kicks off on its own.
- 5Size and season restrictions are tight and shifting — several states now have closed seasons. Check current regulations every trip.
- 6To keep the fish, dispatch it immediately — a firm rap with a priest or knife spine at the top of the skull, just behind and above the eyes. A flounder killed instantly tastes better than one that suffocates in a bucket.
- 7Bleed it right away: cut the two gill arches on one side, or make a single cut behind the pectoral fin to the artery, and hold it in the water for thirty seconds while it pumps out.
- 8Get it on ice — slurry ice (ice plus water plus a little salt) if you have it — within minutes, not at the end of the day. Cold, bled fish is the entire difference between good and muddy-tasting fillets.
14
How to clean, skin, and fillet flounder
Cleaning a flounder the right way takes about four minutes once you know the sequence.
- 1Flounder are flatfish, so you take four fillets, two per side, instead of two.
- 2Lay the fish dark-side up and cut down the lateral line from head to tail until the blade touches the backbone.
- 3Make a second cut behind the head down to the bone, then flatten the blade and work each fillet outward from the centerline to the fin margin, riding the bone spines.
- 4Flip the fish and repeat on the white side. The white-side fillets are thinner but just as good.
- 5Skin each fillet tail-first with the blade flat, or scale and leave the skin on the white-side fillets for grilling.
- 6Trim the thin fin margin off the outer edge; it cooks tough and holds no meat worth keeping.
- 7Ice or freeze immediately. Flatfish flesh is lean and delicate — it flakes apart if it warms up before you cook it.
15
Handling, release, and the table
Flounder is a top-tier table fish — thin, white, sweet fillets that need almost nothing done to them.
Each fish yields four fillets, two per side; a sharp flexible knife makes the job easy.
Pan-fry, broil, or stuff them. Overcooking is the only real risk with flesh this delicate.
Respect the tight seasons — flounder stocks along much of the Atlantic are under active rebuilding.

Questions
Frequently asked
- How do I know I have a bite?
- Usually it just feels heavier, like you've dragged into a piece of cloth. Drop your rod tip, count to three so the fish can turn the bait, then sweep-set.
- When is the flounder run?
- Late September through November in most of the range, as cooling water pushes fish from back bays out through the inlets. That's when they're most concentrated and most catchable.
- What's the difference between fluke and flounder?
- Summer flounder (fluke) are left-eyed and toothy; southern and winter flounder differ in eye side and range. All are fished essentially the same way, but the size limits differ substantially by state.
- Best bait for flounder?
- A live mud minnow or finger mullet, or a bucktail tipped with squid or a Gulp swimming mullet. Presentation on the bottom matters more than the specific bait.
