NMFS has determined that the Atlantic bluefin tuna (BFT) daily retention limit that applies to vessels permitted in the Highly Migratory Species (HMS) Charter/Headboat category (when fishing recreationally for BFT) should be adjusted for the remainder of 2013, based on consideration of the regulatory determination criteria regarding inseason adjustments and based on preliminary 2013 landings data. The adjusted limit for HMS Charter/Headboat vessels is one school BFT and one large school/small medium BFT per vessel per day/trip when fishing recreationally for BFT (i.e., one BFT measuring 27 to less than 47 inches, and one BFT measuring 47 to less than 73 inches). This retention limit is effective in all areas, except for the Gulf of Mexico, where NMFS prohibits targeted fishing for BFT. NMFS also closes the southern area Angling category fishery for large medium and giant ("trophy") BFT. These actions are being taken consistent with the BFT fishery management objectives of the 2006 Consolidated HMS Fishery Management Plan (Consolidated HMS FMP) and to prevent overharvest of the 2013 Angling category quota.
