Winter Flounder

About the Winter Flounder

The Winter Flounder is a right-eyed flatfish, meaning both eyes are typically on the right side of its head when viewed from above. Its top side ranges from dark olive to reddish-brown, often with darker blotches, providing excellent camouflage against the seafloor. The underside is a clean white. These fish have a small mouth and a relatively thick body compared to some other flounder species, growing up to 61 cm (24 inches) in length and weighing over 2 kg (4.5 lbs).

Habitat

This species primarily inhabits shallow coastal waters, estuaries, and bays, favoring sandy or muddy bottoms. They are often found in areas with eelgrass or other submerged vegetation, where they can ambush prey. While common inshore, they may move to slightly deeper offshore waters during the coldest parts of winter or warmest parts of summer.

Distribution

Winter Flounder are native to the western North Atlantic coast, ranging from Labrador, Canada, south to Georgia, United States. They are most abundant and common in near-shore waters from Newfoundland through Massachusetts Bay, becoming less common south of Delaware Bay.

Behaviour

Winter Flounder are opportunistic bottom feeders, burying themselves in the substrate and ambushing small crustaceans, worms, mollusks, and small fish. They are relatively sedentary, moving slowly along the bottom in search of food. Their seasonal behavior involves migrating into shallow bays and estuaries for spawning in late winter/early spring, then moving to slightly deeper or cooler waters as temperatures rise in summer, before returning inshore in the fall.

Edibility

★★★★★

Winter Flounder offers a delicate, mild-flavored white flesh that is highly prized by many anglers. It is excellent pan-fried, baked, or broiled, and holds together well.

Lure suggestion

For anglers, the best approach for Winter Flounder involves using natural baits on a simple bottom rig. Bloodworms, sandworms, clams, or small pieces of squid are highly effective. A high-low rig with small hooks (size 4-8) is ideal, fished directly on the bottom. Bounce the bait slowly along sandy or muddy flats, paying attention to subtle bites.
