NMFS implements approved measures in Framework 4 to the Atlantic Herring Fishery Management Plan. The New England Fishery Management Council developed Framework 4 to further enhance catch monitoring and address discarding in the herring fishery. The approved measures include: A requirement that vessels report slippage (i.e., catch discarded prior to sampling by an observer) via the vessel monitoring system; slippage consequences measures (i.e., requirement to move 15 nautical miles (27.78 km) or return to port following a slippage event); and clarifications to existing slippage measures and definitions. NMFS disapproved two measures in Framework 4. These measures would have required: Fish holds to be certified and observers to collect volumetric catch estimates of total catch; and fish holds to be empty of fish before leaving port, unless a waiver is issued by an authorized law enforcement officer. NMFS disapproved these measures because it determined that they are inconsistent with the Magnuson- Stevens Fishery Conservation and Management Act, the Administrative Procedure Act, and the Paperwork Reduction Act. Therefore, those two measures are not implemented in this action. Lastly, NMFS implements minor corrections to regulations to clarify their intent and ensure they are consistent with the Atlantic Herring Fishery Management Plan.
