Amendment 21 to the Atlantic Mackerel, Squid and Butterfish FMP

The Chub Mackerel Amendment established long-term conservation and management measures for Atlantic chub mackerel (Scomber colias) off the U.S. Atlantic coast by integrating this species as a stock in the fishery under the Mackerel, Squid, and Butterfish Fishery Management Plan (FMP). The amendment established catch limits, accountability measures, and other conservation and management measures required for stocks “in the fishery.” The Council approved the amendment in March 2019, and a final rule was published on August 4, 2020.
