Abstract:
Councils and NMFS are required to review the essential fish habitat (EFH) components of Fishery Management Plans (FMPs) and revise or amend these components based on available information at least every five years (50 CFR 600.815(a)(10)) in an EFH 5-year Review. This study demonstrates advances in EFH component 1 descriptions and identification (maps) based on refinements to the habitatbased species distribution modeling (SDM) approach to mapping EFH established in the 2017 EFH 5-year Review. All of the SDM ensembles constructed for FMP species in the Gulf of Alaska (GOA) in this present work describe and map EFH Level 2 (habitat-related abundance), meeting a key objective of the EFH Research Plan for Alaska. For early juvenile life stages in the GOA, SDMs describe and map EFH Level 1 (distribution) for the first time
