PORTLAND — Fishermen in two of the most lucrative fisheries in the Northeast — Atlantic herring and haddock —are at odds over the management of fishing in Georges Bank, a key nerve center for both species.

Atlantic herring fishermen who fish from mid-water trawl boats are on track this year to exceed their limit for incidental catch of haddock in Georges Bank, off the coast of New England, federal regulators said. That would trigger rules that would effectively shut down the herring fishery.

Herring fishermen are asking the New England Fishery Management Council, an interstate body that manages fisheries, for an emergency action that could include raising their limit for haddock bycatch. But many haddock fishermen are opposed to such a move because they say it would contribute to the depletion of their own fishery.

The council will consider the request at a meeting June 17-19, with a potential vote scheduled for the last day.

One solution could be to temporarily raise the bycatch cap, said Jeff Kaelin, who works in government relations for Lund’s Fisheries of Cape May, New Jersey. He said haddock are abundant enough that heavy recent bycatch isn’t a grave concern.

“It doesn’t make any sense at all to close the herring fishery,” Kaelin said. “It jeopardizes one fishery when the other one isn’t being biologically impacted at all.”

But haddock and other groundfish fishermen would prefer to see solutions such as more on-board monitoring or introduction of gear that reduces bycatch, said Maggie Raymond, executive director of the Associated Fisheries of Maine.

“Groundfishermen are struggling, and they are concerned about someone else taking that fish,” Raymond said, adding that raising the cap “doesn’t address the issue.”

Haddock and herring are key resources for the Northeast fishery, with haddock a staple on seafood restaurant menus and herring playing a particularly critical role as the most popular form of bait for lobstermen.

Herring fishermen are allowed a catch cap of haddock in Georges Bank every year, with 2013 set at 273 metric tons and 2012 set at 286 metric tons. The fishermen exceeded the cap in both years. This year’s cap, for a season that runs from May 1 to April 30, is 179 metric tons. The lower cap and the fact that fishermen have already caught 5 percent of it before summer is concerning, said Chris Kellogg, a deputy director at the New England Fisheries Management Council.

Exceeding the cap would mean herring fishermen would be prohibited from catching more than 2,000 pounds per trip, a number that fishermen said is not enough to justify the trip.

The management council’s decision will come less than a month after the National Marine Fisheries Service said the Gulf of Maine’s Atlantic herring fishery needed to be shut down for nearly a year. That fishery is heavily restricted until May 1, 2015.

The conflict has attracted the interest of outside organizations, including the Pew Charitable Trusts, which intends to send a representative to the meetings. The herring fishery “needs to live within the limits that everyone else lives within,” said Jud Crawford, a manager for science and policy for Pew.
