NMFS delays the effective date of a final rule published January 11, 2000, from March 27, 2000, until April 3, 2000. The final rule was to have been effective February 10, 2000; however, its effectiveness was delayed until March 15, 2000, and again until March 27, 2000. The final rule will implement approved management measures for the spiny dogfish fishery, as contained in the Spiny Dogfish Fishery Management Plan (FMP). This action is being taken in order to provide the Secretary of Commerce with adequate time to evaluate the alternatives offered by the Mid-Atlantic and New England Fishery Management Councils (Councils) before proceeding with implementation of the FMP.
