This final rule approves and implements management measures contained in Amendment 17 to the Atlantic Surfclam and Ocean Quahog Fishery Management Plan. Amendment 17 management measures were developed by the Mid-Atlantic Fishery Management Council to: Add cost recovery provisions for the Individual Transferable Quota component of the fishery; modify how biological reference points are incorporated into the fishery management plan; and remove the plan's optimum yield range. These changes are intended to make the management plan consistent with requirements of the Magnuson-Stevens Act, and to improve the management of these fisheries.
