This rule implements specifications and management measures for the spiny dogfish fishery for the 2013-2015 fishing years consistent with the recommendations of the Mid-Atlantic and New England Fishery Management Councils. The approved commercial quotas represent increases over status quo levels, and the possession limit is also increased. 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.
