The King of Flatfish

From collapse to slow comeback for Atlantic halibut in the Gulf of Maine.

The frigid seas of the Gulf of Maine are home to a diverse blend of bottom fishing opportunities, with species such as cod, haddock, and pollock routinely filling anglers’ boxes. However, famed Atlantic halibut are also once-again beginning to show in increasing numbers. 

Recognized as the largest member of the flatfish family, the Atlantic halibut inhabits a broad range, stretching from the icy waters of Labrador and Greenland across to Iceland, and down through the Canadian Maritimes. Within U.S. waters, Atlantic halibut are most frequently encountered by anglers in the Gulf of Maine. These demersal fish inhabit the seafloor at depths ranging from a few hundred feet to deeper than 6,000 feet. 

The largest Atlantic halibut on record was caught by a commercial angler in the early 1900s off the coast of Cape Ann, Massachusetts. It weighed more than 600 pounds even after the head had been removed.

The Crash of the Atlantic Halibut

Throughout the late 1800s, the growing population centers of the Northeast drove an increasing demand for fresh fish. In response, commercial fleets focused on Atlantic halibut for its impressive size, sweet flavor, and signature flaky texture. Records show that at least 12 million pounds of Atlantic halibut were harvested annually in the Gulf of Maine during this period.

Atlantic halibut are an extremely slow-growing species that require 10 years to reach sexual maturity and can live past 50 years of age. Over time, the extreme fishing pressure began to take its toll, and the U.S. population of halibut had all but crashed by the 1940s. 

Little effort was made to restore the fishery until the early 2000s when the New England Fishery Management Council stepped in to put in place a rebuilding plan, through tactics such as seasonal and year-round area closures, limited commercial and recreational harvest, and annual catch limits, the goal remains to get the population back to a target level by 2055. Yes, that’s another 30 years. 

Atlantic Halibut Rebounds

For an insider’s take on the current state of halibut fishing in the Gulf of Maine, I had the chance to connect with Capt. Bruce Sweet, of Sweet Dream Fishing Charters, based in Gloucester, Massachusetts. Sweet and his team routinely target Atlantic halibut along the Fippennies Ledge section of the Gulf of Maine, an underwater shoal located around 65 miles northeast of Gloucester. 

While the fishing is not consistent, Sweet says, “Over the last 15 years or so, the fishing is trending up; they are hardly abundant, but you are hearing about more and more being caught.” These days, strict recreational regulations continue to help Atlantic halibut maintain growing population levels, with only one fish measuring at least 41 inches able to be harvested per boat, per trip. 

Sweet also highlights that the surge in halibut activity has drawn increased interest from anglers, particularly as New England groundfish species have seen decreased bag limits for the past few years. 

Tips and Tactics for Targeting Halibut

For Sweet, the peak of his halibut fishing season occurs toward the end of May, into early July. The biggest reason for this is that once the Gulf of Maine hits a water temperature of 60 degrees, the area becomes inundated with dogfish and blue sharks that make getting any fish to the boat nearly impossible. 

Offshore shoals with depths of 200 to 300 feet, featuring gravel bottoms or scattered boulders, are great areas to start. While most halibut are caught as bycatch during pollock and haddock trips, targeting areas with abundant bait and other biomass is important. Along with Fippennies Ledge, anglers might also consider making the trip to Jeffreys Ledge off the coast of New Hampshire, where commercial tuna fishermen and recreational ground fishermen occasionally hook halibut that rise from the bottom to strike suspended live baits.

The massive specimens of the past are still a distant memory. Sweet reports that most fish caught by his clients weigh between 50 and 60 pounds, with the largest of his career surpassing 90 pounds. As a result, using the right gear to bring large fish up from deep water is essential. Anglers typically target Atlantic halibut with traditional three-sided Norwegian jigs, often accompanied by a series of teasers, ranging from 12 to over 20 ounces to account for current — requiring heavy conventional tackle to impart action and maintain bottom contact.

While the full recovery of the Atlantic halibut population remains uncertain, strict regulations and careful management are driving the species’ resurgence, giving anglers the opportunity to target these remarkable fish once more. With continued efforts, one day it may not take a trip to Alaska for U.S. anglers to wrestle with the king of flatfish.
