NMFS issues final specifications for the 2019 spiny dogfish fishery, and projected specifications for fishing years 2020 and 2021. The specifications are necessary to establish allowable harvest levels and other management measures to prevent overfishing while allowing optimum yield, consistent with the Magnuson-Stevens Fishery Conservation and Management Act and the Spiny Dogfish Fishery Management Plan. This rule is also intended to inform the public of these specifications for the 2019 fishing year and projected specifications for 2020 and 2021.
