Essential Fish Habitat (EFH) - Magnuson Stevens Fishery Conservation Management Act

Several of the following are PDF files which require free Adobe Acrobat Reader software to view, navigate and print. Adobe also offers free tools for the visually disabled.

In 1996 Congress added new habitat provisions to the Magnuson-Stevens Fishery Conservation

and Management Act, the federal law that governs U.S. marine fisheries management. Under the Magnuson-Stevens Act, each fishery management plan must describe and identify EFH for the fishery, minimize to the extent practicable the adverse effects of fishing on EFH, and identify other actions to encourage the conservation and enhancement of EFH. Federal agencies must consult with NMFS regarding any action they authorize, fund, or undertake that may adversely affect EFH, and NMFS must provide conservation recommendations to federal and state agencies regarding any action that would adversely affect EFH.

As Congress noted in section 2(a)(9) of the Magnuson-Stevens Act, "One of the greatest long-term threats to the viability of commercial and recreational fisheries is the continuing loss of marine, estuarine, and other aquatic habitats. Habitat considerations should receive increased attention for the conservation and management of fishery resources of the United States."

  • 67 FR 2343, January 17, 2002.
    Final rule for implementing the EFH provisions of the Magnuson-Stevens Fishery Conservation and Management Act. These regulations provide guidelines for fishery management councils to identify and conserve EFH, as well as procedures for interagency coordination and consultation regarding actions that may adversely affect EFH. The preamble to the final rule provides background information and addresses many issues raised through public comment.



  • EFH Descriptions and Identification
    blue line
    EFH in Alaska is identified in Fishery Management Plans developed by the North Pacific Fishery Management Council and approved by the Secretary of Commerce. EFH descriptions are comprised of text and maps. (If there are differences between the descriptions of EFH in text and maps, the textual description is ultimately determinative of the limits of EFH.)

  • EFH Text Descriptions
    Text descriptions identify EFH for each life stage of fish managed under a Fishery Management Plan within the Gulf of Alaska, Bering Sea, and Aleutian Islands.

  • EFH Map Descriptions (ArcIMS website)
    Maps depict the area of EFH for each life stage of fish managed under a Fishery Management Plan within the Gulf of Alaska, Bering Sea, and Aleutian Islands.

  • Species Profiles and Habitat Assessment Reports
    Detailed reports provide information about each species, including any known habitat associations, reproductive traits, predator prey relationships, and species-specific literature citations.
