NMFS announces that, effective 0001 hr, February 24, 2012, federally permitted vessels may not fish for, catch, possess, transfer, or land more than 2,000 lb (907.2 kg) of Atlantic herring in or from Management Area 1B per calendar day until January 1, 2013, when the 2013 sub-ACL for Area 1B becomes available, except when transiting as described in this notice. This action is based on the determination that the revised Atlantic herring sub-ACL limit allocated to Area 1B for 2012 has been exceeded as of February 24, 2012.
