This action decreases the possession limit for Southern New England/Mid-Atlantic winter flounder and Gulf of Maine haddock for Northeast multispecies common pool vessels for the remainder of the 2013 fishing year. NMFS is taking this action because the common pool has caught 73 percent of its Southern New England/Mid-Atlantic winter flounder quota, and 96 percent of its Gulf of Maine haddock quota. This action is intended to prevent the overharvest of the common pool's FY 2013 allocation of Southern New England/Mid-Atlantic winter flounder and Gulf of Maine haddock.
