NMFS partially approves and implements through regulations measures included in the Mid-Atlantic Unmanaged Forage Omnibus Amendment, as adopted by the Mid-Atlantic Fishery Management Council and approved by NMFS on June 13, 2017. The purpose of this action is to prevent the development of new, and the expansion of existing, commercial fisheries on certain forage species until the Council has adequate opportunity and information to evaluate the potential impacts of forage fish harvest on existing fisheries, fishing communities, and the marine ecosystem. This final rule implements an annual landing limit, possession limits, and permitting and reporting requirements for Atlantic chub mackerel and certain previously unmanaged forage species and species groups caught within Mid-Atlantic Federal waters; allows vessels to transit Mid-Atlantic Federal waters with forage species caught in other areas; and identifies measures that can be revised through a future framework adjustment.
