PORTLAND, Maine (AP) — Commercial fishermen who trawl for herring off the coast of New England will not be allowed to exceed their incidental haddock catch limit this year after a ruling in a dispute pitting two of the Northeast’s key fisheries against each other.

Atlantic herring fishermen who fish from mid-water trawl boats are on track to exceed their bycatch of haddock in Georges Bank, off the coast of New England, federal regulators have said. That would trigger rules that would prohibit fishermen from catching more than 2,000 pounds per trip — effectively shutting down the herring fishery.
