Summer flounder are a highly prized fish sought by both commercial and recreational fishermen throughout Maryland. Found in estuarine and coastal waters from Nova Scotia to Florida during spring to fall, they move offshore to depths of 100 to 600 feet during the winter.

Their migration is presumably brought on by decreasing water temperatures and declining photoperiods in the fall.​ They are most abundant from Cape Cod, Massachusetts to Cape Fear, North Carolina and can be found in Maryland’s Chesapeake Bay, largely restricted to waters south of Annapolis, and occasionally in the upper Bay.


Summer Flounder

FlounderThis left-eyed flatfish has both eyes on the left side of its body. Its "eyed" side is scattered with 10 to 14 eye-like spots which blend in with the ocean floor and it has a white belly. Its belly or underside is white.​ Summer flounder average between 3-6 pounds and 15"-22" (40-56 cm.) long.​

They spend most of their lives on or close to the bottom, as other flatfishes do, and use their flattened shape and ability to change coloration and pattern on the eyed side of their bodies to partially burrow in the sediment, lie in ambush and wait for their prey.​


The summer flounder season is open year-round. Though high season is during the summer months while the waters are warmer.


The recreational fishery for summer flounder in the Maryland portion of the Chesapeake Bay occurs in late summer from the Bay Bridge south, with the greatest amount of effort closer to the Virginia line and the mouth of the Potomac River. The most popular baits are minnows and squid strips, and drifting is the most popular method of fishing.

Participate in the Summer Flounder Volunteer Angler Survey

Participation in the Volunteer Angler Summer Flounder Survey is VERY important to summer flounder management along the East Coast. Anglers who participate in the Summer Flounder Volunteer Angler Survey will help guide the Department's management approach for both the Chesapeake Bay and Atlantic Coast populations. To participate in this important survey, visit http://www.dnr.state.md.us/fisheries/survey/index.asp or contact DNR at 1-877-620-8DNR, ext. 8311. A packet with forms and postage paid envelopes is available to anglers that do not wish to participate through the Internet.
