Description

Amendment 24 to the U.S. federal Fishery Management Plan (FMP) for Commercial King and Tanner Crab Fisheries in the Bering Sea and Aleutian Islands was made in 2007 and implemented for the 2008 fisheries. The amended FMP specifies a five-tier system to which each stock under the purview of the plan is assigned and which is used for setting the overfishing and overfished levels. The primary differences between the amended FMP and the preceding FMP are twofold: (1) the biomass currency (mature male biomass vs. total male plus female mature biomass); and (2) the limit catch (total removal from all fisheries vs. retained catch removal from the directed fishery). Thus, the amended FMP considers the effect of total removals from the ecosystem on stock productivity and also the direct impact of fishery removal of males on reproductive output. In this paper, in addition to providing some guidance for developing control rules under the amended FMP, we compare the merit of the amended control rule over the old control rule considering two major crab fisheries, Bristol Bay red king crab, Paralithodes camtschaticus, a recovered stock, and eastern Bering Sea snow crab, Chionoecetes opilio, a depleted and recovering stock. We discuss the regime shift consideration made when developing the old and amended FMPs.
