NMFS issues this interim final rule to amend regulations implemented through emergency interim rule for the Atlantic deep-sea red crab (Chaceon quinquedens) (red crab) fishery. This interim final rule revises the conversion factor for determining equivalent live weight of landings where red crab are landed in a butchered state. The intent of this interim final rule is to allow vessels that butcher at sea to land a true live weight equivalent trip limit, currently set at 65,000 pounds (29.5 metric tons (mt)).
