Gillnets, longlines, and rod and reel used to harvest haddock have little to no impact on habitat. Areas closures and gear restrictions reduce habitat impacts from trawl nets. Fishermen follow management measures to designed to reduce interactions with marine mammals, including gear modifications, seasonal closures, and use of marine mammal deterrents. Recreational fishery: Haddock are highly prized by recreational fishermen.

Population

The Gulf of Maine and Georges Bank stocks are not overfished.

Fishing Rate

Not subject to overfishing.

Habitat Impacts

Area closures and gear restrictions protect habitat that are affected by some kinds of trawl gear.

Bycatch

Regulations are in place to minimize bycatch.

Management

There are two stocks of haddock in U.S. waters, the Gulf of Maine and Georges Bank stocks. NOAA Fisheries and the New England Fishery Management Council manage Gulf of Maine haddock; NOAA Fisheries and the New England Fishery Management Council collaborate with Canada to jointly manage Georges Bank haddock, because the stock spans both waters.
