NMFS is implementing final 2012 specifications and management measures for the butterfish fishery, which is managed as part of the Atlantic Mackerel, Squid, and Butterfish Fishery Management Plan. This action requires a 3-inch (76-mm) minimum codend mesh size in order to possess more than 2,000 lb (0.9 mt) of butterfish (up from 1,000 lb (0.45mt)). These specifications and management measures promote the utilization and conservation of the butterfish resource.
