Ocean City Fishing: The White Marlin Capital and the Canyons That Made It Famous

Ocean City earned its White Marlin Capital nickname in 1939, and the offshore canyons that created that reputation still produce marlin, tuna, and swordfish alongside a back-bay flounder fishery that locals guard like a secret.

Ocean City, Maryland sits on a barrier island between the Atlantic Ocean and the Isle of Wight and Assawoman Bays. The town has called itself the White Marlin Capital of the World since 1939, when 171 white marlin were boated in a single day from the offshore waters, a catch rate that established the reputation and launched a tournament scene that continues today.

The offshore canyons, Baltimore, Poor Man's, Washington, Norfolk, lie 50 to 80 miles southeast, and they hold white marlin, blue marlin, yellowfin tuna, bigeye tuna, swordfish, and wahoo in a seasonal rotation that keeps the charter fleet running from May through November. But Ocean City isn't just an offshore town. The back bays hold a flounder, striper, and sea bass fishery that's productive, accessible, and often overlooked by visitors focused on the marlin fleet.

The Canyons, Marlin, Tuna, and the Tournament Scene

The submarine canyons off Ocean City are cuts in the continental shelf where deep water pushes close to the edge, creating upwellings of nutrient-rich water that feeds the entire food chain. The result is a concentration of blue-water species at distances that are long but reachable on a single-day charter.

White marlin are the signature species. They show up in June and the bite builds through summer, peaking in August, which is when the White Marlin Open, one of the largest and richest billfish tournaments in the world, runs out of Ocean City. The tournament regularly pays out millions in prize money, and the weigh-ins at Harbour Island draw thousands of spectators.

White marlin are caught by trolling ballyhoo, squid, and artificial spreads along the canyon edges and temperature breaks. They're catch-and-release in most situations, and the sight of a white marlin lighting up behind the spread, blue and purple bars flashing on its body, is the defining image of Ocean City offshore fishing.

Blue marlin are less common but present from June through September. Fish over 500 pounds have been caught in the canyons off Ocean City.

Yellowfin tuna stack along the canyon edges from late spring through fall. The tuna bite can be outstanding, chunking at the edge of the canyon, dropping live bait into the color change, and hooking fish that run 30 to 80 pounds. Bigeye tuna are the deep-water prize, caught on nighttime trips or deep-drop techniques.

Swordfish have become a growing fishery, daytime deep-drop swordfishing in 1,000 to 1,500 feet of water produces broadbills that most anglers have never caught. It's specialized work, but the Ocean City fleet is experienced at it.

The Back Bays, Flounder Country

The Isle of Wight Bay and Assawoman Bay sit behind the barrier island, connected to the ocean through the Ocean City Inlet. These shallow, protected bays hold a flounder fishery that rivals anywhere on the mid-Atlantic coast.

Flounder (summer flounder/fluke) are the back-bay headliner. They lie on the sandy and muddy bottom along channel edges, near bridge pilings, and around the inlet jetties, ambushing bait that drifts past. Drifting with bucktail jigs tipped with minnow, squid, or Gulp strips is the standard technique. Doormat flounder, fish over seven pounds, are caught in the back bays every season.

Striped bass (rockfish) run the bays and surf from spring through early winter. The fall striper run brings big fish through the inlet, and casting to them from the jetties or the Route 50 bridge is a local tradition.

Sheepshead, tautog (blackfish), black sea bass, and bluefish round out the inshore and nearshore options, with each species peaking in its own season.

Pier and Surf Fishing

Ocean City's beach and the inlet jetties provide shore-based access. Kingfish (whiting), spot, croaker, and bluefish are caught from the beach. The inlet jetties produce stripers, flounder, sheepshead, and tautog, the rock structure concentrates fish in a narrow area.
