This rule implements a catch limit, commercial quota, and possession limit for the spiny dogfish fishery for the 2012 fishing year. The action was developed by the Mid-Atlantic and New England Fishery Management Councils pursuant to the fishery specification requirements of the Spiny Dogfish Fishery Management Plan. The final management measures are supported by the best available scientific information and reflect recent increases in spiny dogfish biomass. The action is expected to result in positive economic impacts for the spiny dogfish fishery while maintaining the conservation objectives of the Spiny Dogfish Fishery Management Plan.
