This final rule implements Framework Adjustment (FW) 42 to the Northeast (NE) Multispecies Fishery Management Plan (FMP) and FW 3 to the Monkfish FMP (Joint Framework). FW 42, developed by the New England Fishery Management Council (Council), is a biennial adjustment to the NE Multispecies FMP that sets forth a rebuilding program for Georges Bank (GB) yellowtail flounder and modifies NE multispecies fishery management measures to reduce fishing mortality rates (F) on six other groundfish stocks in order to maintain compliance with the rebuilding programs of the FMP. FW 42 also modifies and continues specific measures to mitigate the economic and social impacts of Amendment 13 to the FMP and to allow harvest levels to approach optimum yield (OY).
