AbstractEssential Fish Habitat (EFH) 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, Aleutian Islands, and Arctic. EFH shapefiles were created by Region (AI, BS, GOA, Arctic) and life stage.

| Abstract: |
Essential Fish Habitat (EFH) 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, Aleutian Islands, and Arctic. EFH shapefiles were created by Region (AI, BS, GOA, Arctic) and life stage. |
| Purpose: |
These maps represent the latest updates to EFH in the Alaska Region as of 2023. 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). Species Profiles and Habitat Assessment Reports provide information about each species, including any known habitat associations, reproductive traits, predator prey relationships, and species-specific literature citations. |
