NMFS approves and implements 2025-2026 specifications for the Mackerel, Squid, and Butterfish Fishery Management Plan (FMP), as recommended by the Mid-Atlantic Fishery Management Council (Council). This action sets 2025 and projected 2026 butterfish fishery specifications and reaffirms 2025 chub mackerel, Illex squid, longfin squid, and Atlantic mackerel fishery specifications. These final specifications are intended to establish allowable harvest levels that will prevent overfishing, consistent with the most recent scientific information. This action also adjusts the minimum square mesh size for directed butterfish trawl trips and corrects existing regulations.
