Sustainability Story

Smart Choice

Although populations are well below target levels, U.S. wild-caught Atlantic halibut is still a smart seafood choice because it is sustainably managed under a rebuilding plan that allows limited harvest by U.S. fishermen.

Stock Structure

The Atlantic halibut stock is at a very low level. Fishing is still allowed, but at reduced levels. According to the 2024 stock assessment, the Atlantic halibut stock is overfished. Summary stock assessment information can be found on Stock SMART .

Population

The stock is overfished, but the fishing rate established under a rebuilding plan promotes population growth.

Fishing Rate

Overfishing status is unknown, but catch is at recommended level.

Habitat Impacts

Trawl gear used to harvest Atlantic halibut have minimal or temporary effects on habitat. Area closures and gear restrictions protect sensitive habitats from bottom trawl gear. Hook and line gear has little or no impact on habitat.

Bycatch

Regulations are in place to minimize bycatch.

Management

NOAA Fisheries and the New England Fishery Management Council manage Atlantic halibut. Atlantic halibut, along with other groundfish in New England waters, are managed under the Northeast Multispecies Fishery Management Plan, which includes: Permitting requirements for commercial vessels.
