Flounder are the masters of ambush. They lie camouflaged flat on the bottom — both eyes on top — waiting to lunge upward at passing baitfish with surprising speed. They’re among the best-tasting fish in the sea, they’re available across both coasts and the Gulf, and they’re consistently underrated as sport fish. The challenge is finding them (they’re invisible against the bottom) and presenting bait in their strike zone (just off the bottom, moving slowly).
Summer vs Southern Flounder
Summer flounder (fluke) dominate the Northeast coast from Maine to the Carolinas. Southern flounder are the primary species in the Gulf of Mexico and South Atlantic. Both species behave similarly: ambush predators in shallow coastal waters, estuaries, jetties, and inlets.
Gear Setup for Flounder
7’–7’6″ medium to medium-heavy spinning rod, 2500–3500 reel, 15–20 lb braid with 12–20 lb fluorocarbon leader. Hooks: 2/0–4/0 circle or wide-gap hooks for live bait; 3/0–5/0 wide-gap for soft plastics. Keep the weight as light as possible — just enough to maintain contact with the bottom.

| Bait | Notes |
|---|---|
| Live finger mullet (2–3″) | #1 flounder bait everywhere; fish on 2/0 hook with minimal weight |
| Live mud minnows / killifish | Hardy, stay lively long; ideal for drifting shallow areas |
| Live shrimp | Excellent in the Gulf; hook through the horn for maximum action |
| Gulp! Alive (shrimp, grub) | Best artificial flounder bait — scent + action combination is unmatched |
| Soft plastic paddle tails (3–4″) | White or chartreuse; slow-roll just above bottom |
| Cut squid | Works when baitfish not available; thread on hook and fish near bottom |
How to Fish for Flounder
Drift fishing (most productive): Use a Carolina rig (3/4 oz egg sinker, swivel, 18″ leader, 3/0 hook with live mud minnow) and drift with the current over sandy bottom near inlet mouths, jetties, and channel edges. Keep contact with the bottom — you should feel occasional tick-tick-tick as the weight bounces along. Flounder often follow the bait for several feet before striking, so use a long, slow pause when you feel a tap.
Jigging structure: Drop a Gulp! shrimp or paddle tail on a 1/4–1/2 oz jig head to the bottom near dock pilings, rocks, or shell bottom. Hop it 3–6 inches off bottom and let it fall dead. Flounder attack on the drop.
Flounder Gigging
Gigging is the most effective flounder fishing method available. At night, wade or pole a shallow flat with a powerful light and a multi-pronged gig (spear). Flounder are startled by light and freeze, making them easy targets. Legal in most Gulf states; check regulations for seasons and limits. Gigging can produce dozens of fish per night in productive areas.
Flounder Seasonal Guide
| Season | Location | Notes |
|---|---|---|
| Spring (Apr–Jun) | Shallow estuaries, grass flats | Fish moving into shallows to feed |
| Summer (Jun–Aug) | Inlets, jetties, structure | Best jigging season |
| Fall Run (Sep–Nov) | Inlet mouths, passes | Flounder migrate offshore — best catch-rates of the year |
| Offshore (Nov–Feb) | Nearshore reefs 30–60 ft | Winter offshore spawning aggregations |
