Essential Fish Habitat (EFH)
Fish and other marine species depend on habitats comprised of the biological and physical properties required for survival and successful reproduction. In Alaska, we work to identify and protect essential fish habitat - habitat necessary for marine species to complete their lifecycles - in the waters of the North Pacific and Arctic Oceans off Alaska, as mandated by the Magnuson-Stevens Fishery Conservation and Management Act and other legislation.
Descriptions and Identification
Essential Fish Habitat 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 are the legal definition for EFH and serve as the "basis" for effect determinations. EFH text describes the physical and biological environment and the location of EFH for each species by life history stage, if known. Species profiles and habitat assessment reports within the Fishery Management Plans provide information about each species, including any known habitat associations, reproductive traits, predator prey relationships, and species-specific literature citations.
EFH maps complement EFH text descriptions and spatially 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, and the Arctic.

Federal agencies must consult with NOAA Fisheries regarding any action authorized, funded, or undertaken, or proposed to be authorized, funded, or undertaken that may adversely affect EFH.

Habitat Areas of Particular Concern
Habitat Areas of Particular Concern (HAPCs) are smaller habitat areas within EFH that meet at least two of the four considerations: 1)The importance of the ecological function provided by the habitat; 2) The extent to which the habitat is sensitive to human-induced environmental degradation; 3) Whether, and to what extent, development activities are, or will be, stressing the habitat type; 4) The rarity of the habitat type. (Rarity is a mandatory criterion of all Council HAPC proposals.)
