Pursuant to the Coastal Pelagic Species (CPS) Fishery Management Plan (FMP), every other June, the Pacific Fishery Management Council (Council), under the Magnuson-Stevens Fishery Conservation and Management Act, adopts and recommends to NMFS harvest specifications and management measures for Pacific mackerel in the U.S. exclusive economic zone off the Pacific coast of California, Oregon, and Washington for the upcoming two fishing years. The Pacific mackerel fishing season begins on July 1 and ends June 30. NMFS plans to issue proposed and final rules to implement those harvest specifications for the 2023-2024 and 2024-2025 fishing years as recommended by the Council at its June 2023 meeting. Harvest specifications include harvest guidelines for each fishing year, which will serve as the primary commercial harvest quotas, and management measures, including incidental catch limitations in the event an annual catch target is reached. The CPS FMP and its implementing regulations require NMFS to set these annual harvest specifications, including the harvest guideline, for the Pacific mackerel fishery based on the annual specification framework and control rules in the FMP.
