This rule proposes to implement an action of the Northern Pacific Fishery Management Council by revising Federal regulations to prohibit directed fishing for those species with sideboard limits that are not large enough to support directed fishing by non-exempt American Fisheries Act vessels in the Bering Sea/Aleutian Islands and Gulf of Alaska and crab vessels in the Crab Rationalization Program (CR Program) in the Gulf of Alaska, or for those species that are fully allocated to other programs (e.g., flathead sole, rock sole, Western Aleutian Islands Atka mackerel). NMFS would then no longer publish American Fisheries Act and CR Program sideboard amounts for those species in the annual harvest specifications. In addition, the action would remove the sideboard limit on American Fisheries Act catcher/processors for Central Aleutian Islands Atka mackerel because the sideboard limit under the American Fisheries Act (11.5 percent) is constrained by the allocation to the trawl limited access sector (10 percent) that was established by the Amendment 80 Program. The primary benefits of this action are that it would streamline the annual harvest specifications, reduce the annual costs of preparing and publishing the annual harvest specifications in the Federal Register, and simplify NMFS' annual programming changes to the agency’s groundfish catch accounting system. This action would not alter how NMFS actually manages the relevant sideboard limits, and NMFS would continue to monitor Bering Sea/Aleutian Islands and Gulf of Alaska groundfish catch to ensure that each species' total allowable catch limit is not exceeded. This action would not incur any negative impacts to American Fisheries Act and crab sideboard limited vessels for the foreseeable future.
