Available in PDF, EPUB and Kindle. Book excerpt: In 1980 and 1981, more than 68,000 juvenile halibut were tagged in the Gulf of Alaska and Southeast Alaska in an effort to obtain estimates of movements of juvenile halibut. In this paper we develop a maximum likelihood method for estimating the movement between International Pacific Halibut Commission (IPHC) regulatory Areas 3B, 3A, 2C, 2B and 2A. In addition to the movement rates, we also estimate the sizespecific natural mortality, tagging mortality and size selectivity for commercial gear in Areas 3B and 3A. We found that all of these parameters could be estimated with low confounding, and that the predicted recovery pattern of tags conforms closely to the observed recoveries. The best fitting model estimates that there are substantial southerly movements of juvenile halibut; for example, we estimate that 17% of fish tagged in 3B would recruit as adults to 2B, and that 25% of fish tagged in 3A would recruit as adults to 2B. Further improvements in the analysis could include smaller spatial scale of analysis, and combining tagging analysis with catch-at-age data.

This book was released on 2013 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This analysis examines proposed changes to the management of Pacific halibut in the charter fisheries and commercial setline fisheries in International Pacific Halibut Commission (IPHC) Regulatory Areas 2C and 3A in the Gulf of Alaska. The North Pacific Fishery Management Council (Council) identified a need to develop a catch sharing plan (CSP) for the charter and commercial sectors to address conservation and allocation concerns in both areas. These concerns resulted from: 1) increased harvests in the charter halibut fishery, and 2) decreased catch limits in the commercial setline fisheries. The Council considered five alternatives and adopted a Preferred Alternative from among proposed CSP elements. The Council adopted its Preferred Alternative using the proposed charter allocations under Alternative 3 for Area 2C and the proposed charter allocations under Alternative 4 for Area 3A. The Council also adopted revised elements for a Guided Angler Fish Program, in which Charter Halibut Permit holders would be allowed to lease commercial Individual Fishing Quota in order to provide charter anglers with harvesting opportunities, not to exceed limits in place for unguided anglers. Annual management measures would be implemented each year through a cooperative program among state and Federal agencies. The Council also would request that the IPHC: 1) annually set a combined charter and commercial setline catch limit, to which the allocation percentage for each area would be applied to establish the domestic harvest allowances for each sector and 2) implement separate accountability of halibut removals for each sector. Upon implementation, the Alaska Department of Fish and Game logbooks would be used as the primary data source for estimating charter halibut harvest. The Council intends that the CSP would be implemented by National Marine Fisheries Service for 2014, which is the earliest possible timeline.
