1

Know it

Spot it, size it up and learn its habits.

Identification

Flat, left-eyed flounder (both eyes on the left side) with a big mouth full of sharp teeth; brown back with 5–14 eye-like spots that can change shade to match the bottom.

Typical size

15–22 in and 1–4 lb; fish over 8 lb are called doormats.

Maximum size

About 37 in and over 20 lb.

Diet

Small fish such as sand eels, silversides and killifish, plus squid, shrimp, crabs and worms.

Behavior

Lies buried on sandy or muddy bottom and ambushes food that drifts past.

Find it

Where, when and how deep to look.

Where to find it

Found from Georgia & South Carolina, North Carolina, Virginia & Chesapeake Bay, Delaware & New Jersey, New York, Long Island & Connecticut and Rhode Island & Massachusetts. Sandy and muddy bottom in bays, inlets and channels in early summer, then ocean lumps, wrecks and reefs as summer goes on; most common from North Carolina to Cape Cod.

Habitat

Sandy and muddy bottom in bays, inlets and channels in early summer, then ocean lumps, wrecks and reefs as summer goes on; most common from North Carolina to Cape Cod.

Depth

3–30 ft in bays and inlets, 40–100 ft offshore later in the season.

Fishing depth

On the bottom: 5–30 ft in bays and inlets, 40–100 ft on ocean lumps and wrecks.

Best season

Spring through fall, moving from the bays to the ocean as summer goes on.

Best time

Daylight on a moving tide.

Best tides

A steady drift on a moving tide is best; slack water slows the bite.

Best weather / conditions

Light wind for a slow, steady drift.

3

Bait & gear

What to tie on and what to throw.

Best bait

Live minnows (killies), squid strips, fresh fluke-belly or sea-robin strips, and live spot or snapper blues for big fish.

Best artificial lures

White or pink bucktails tipped with a soft-plastic grub or squid strip, and a teaser hook above the bucktail.

Tackle setup

7 ft medium spinning or conventional rod.

Hook size

2/0–4/0 wide-gap or circle hooks; 1/2–3 oz bucktails.

Line

15–30 lb braid.

Leader

20–30 lb fluorocarbon, 2–3 ft.

Catch it

Step by step, from first cast to landing.

Step-by-step: how to catch it

  1. Go where it lives: Sandy and muddy bottom in bays, inlets and channels in early summer, then ocean lumps, wrecks and reefs as summer goes on; most common from North Carolina to Cape Cod.
  2. Rig up: 7 ft medium spinning or conventional rod. 20–30 lb fluorocarbon, 2–3 ft.
  3. Pick your bait: Live minnows (killies), squid strips, fresh fluke-belly or sea-robin strips, and live spot or snapper blues for big fish. Lures: White or pink bucktails tipped with a soft-plastic grub or squid strip, and a teaser hook above the bucktail.
  4. Fish it: Drift the edges of channels and drop-offs with the bait bouncing on the bottom. When you feel weight, count to two and lift into the fish.
  5. Time it: Daylight on a moving tide. A steady drift on a moving tide is best; slack water slows the bite.
Fishing techniques

Drift the edges of channels and drop-offs with the bait bouncing on the bottom. When you feel weight, count to two and lift into the fish.

BigJoe's tip

Keep the bucktail touching bottom on every bounce β€” fluke look up to eat, and a big one usually hits the teaser first.

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 β€” one of the best-tasting fish in its range.

Cleaning

Fillet it like any flounder: four fillets, two from each side, then skin them.

Cooking suggestions

White, mild, flaky meat: fry, broil, bake or stuff it. Fresh fluke is also great raw (sashimi or ceviche).

6

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Sharp teeth β€” use pliers to unhook.

Regulations

Managed by the states with NOAA Fisheries and the ASMFC: each state sets its own minimum size (usually 16–19 in), bag limit and season. Saltwater licenses and limits are set by each state (VMRC, NJ Fish & Wildlife, NYS DEC, CT DEEP, RI DEM, MA DMF, NH Fish & Game, Maine DMR) and by NOAA Fisheries and the Atlantic States Marine Fisheries Commission β€” check the current rules for your state before you keep fish.

Conservation

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