This book was released on 2009 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The total revenue of the Bristol Bay, Alaska sockeye salmon, Oncorhynchus nerka, fishery has continued to decline despite strong run sizes. This decline is primarily attributed to increases in production of farmed Chilean rainbow trout O. mykiss and coho salmon, O. kisutch. Although wild salmon managers have less control over production than salmon farmers, there may be some opportunity to regain value to the fishery by altering management strategies. To explore this potential, we first simulated three management strategies for sockeye salmon: a fixed escapement range strategy, a fixed harvest strategy and a fixed harvest rate strategy. Yields from these simulations were then combined with a forecast of farmed Chilean trout and salmon production and a model of international trade flows for Alaskan sockeye and Chilean coho salmon and rainbow trout to generate forecasts of exvessel price and total revenue for 2010. All three management strategies were able to achieve a run size equilibrium indicating biological sustainability. The highest median yield resulted from the fixed escapement strategy and the lowest median yield was generated by the fixed harvest strategy. Exvessel prices and total revenue were highest under the fixed harvest strategy. These results demonstrate a switch to an inelastic market environment and reveal the need to modify current management strategies to improve the economic health of the fishery"--Leaf iii.

Available in PDF, EPUB and Kindle. Book excerpt: Market forces, particularly consumer buying power, have the potential to protect and sustain ecological and socio-economic health. This capstone paper examines this potential in the context of the commercial fishing industry in Bristol Bay, Alaska, particularly in light of important land use and development regulatory shifts presently occurring in the region0́4shifts that place Bristol Bay and its salmon fishery at a critical crossroads. One route is to further develop and enhance the commercial fishery, which at its core depends on the ecological health of fish habitat; the alternative is to open the region to new industrial development of non-renewable resources, such as oil, gas, and minerals. In support of finding ways to optimize both the profitability and sustainability of the Bristol Bay fishery, rather than risking its demise at the hands of more harmful industries, this paper analyzes the applicability of certain alternative economic strategies, such as Fair Trade, to the situation in the region, and explores the potential for conservation-based marketing of Bristol Bay Wild Salmon. Research methodology includes a literature review, expert interviews, a consumer survey, and a case study. Results of this research illuminate existing problems in the fishery, particularly poor product quality, disconnect between harvesters and consumers, and a vast lack of consumer knowledge about Bristol Bay salmon and the region in general. Findings from this study suggest that the fishery must embrace change, not only to meet the needs of all of its stakeholders, but ultimately to survive. New models of trade, from harvest to point of sale, for Bristol Bay salmon will support positive changes that might better distribute earnings from the fishery. Increasing the value of this wild fishery will increase the security and value of the pure and pristine habitat and the traditional regional community that sustain it.

This book was released on 2011 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This is an analysis of the environmental, economic, and social effects of implementing a fishing capacity reduction program for the purse seine salmon fishery occurring in Southeast Alaska. The capacity reduction program would be implemented pursuant to authorizing legislation and applicable provisions of the Magnuson-Stevens Fishery Conservation and Management Act (16 U.S.C. 1861a (b-e)). Two alternatives have been considered: (1) no buyback program and (2) an industry funded buyback program. The environmental issues associated include: the biological environment including the water column and substrate; amount of fish removed, environmental impacts of the gear used to fish, and any incidental taking of a marine mammal, seabird, or prohibited species by the Southeast AK purse seine salmon fishery. Under the buyback program potential impact to the physical and biological environment would not change from the status quo because the amount of fish harvested and gear used to harvest fish would not change. Under the proposed program fewer total vessels would be harvesting fish, however each vessel participating would be using the same gear and would be spending more time at sea so fishing effort would not change"--Cover letter; Portfolio comprised of three related PDF documents digitized and organized by: NOAA Office of Program Planning and Integration (PPI) National Environmental Policy Act (NEPA) staff.

This book was released on 2007 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Overescapement of salmon is defined by the Alaska Department of Fish and Game as escapements that are above the range of the current escapement goal. The understanding of how overescapement affects long and short term yields is dependent on knowledge of the production relationship and the amount of fishing power. This document reports the results of the analyzed brood and run information from 40 Alaska sockeye salmon, Oncorhynchus nerka, stocks to determine the biological and fishery-related effects of overescapement.

Book excerpt: Without a doubt, the salmon fishery in Alaska has been at the forefront of natural resource debates and has served as an example of ineffective, misunderstood, and controversial policies, as well as many missed opportunities to better understand the resource. Management of Alaska's longest lasting natural resource industry is contingent upon an evolving scientific understanding of salmon. At the same time, policy has been shaped by political, economic, cultural, and social phenomena. Considering these parts of the historical narrative of the Alaska salmon industry demonstrates the fundamental challenges of fisheries management: reconciling biological limitation, economic demands, and cultural practices. This study contextualizes modern salmon management in Alaska by analyzing early- to mid-twentieth century conservation efforts within these constraints. To begin, some fundamental questions arise in the analysis of salmon management: why did managers make the decisions they did? What were limits faced by managers and the science they relied on? Also, how did political, economic, and cultural forces impact these decisions? By addressing these questions in a historical analysis, a fuller understanding of modern salmon management in Alaska is found. Answering these questions shapes this thesis and supports the argument that economic, political, and cultural factors often influenced changing policies as much as technological advances and ecological understanding did. In particular, Alaska's unique transition to statehood in the mid-twentieth century - a period when huge advances in ecology were underway - highlights how science often took a backseat to other concerns.

Download or read book Using Strontium Isotopes to Track Pacific Salmon Migrations in Alaska written by Sean Reiss Brennan and published by . This book was released on 2014 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pacific salmon (Oncorhynchus spp.) are an important cultural, ecological, and economic natural resource in Alaska. Not only do salmon maintain an important mechanism of nutrient transport between marine, aquatic, and terrestrial ecosystems, but they also provide a sustainable food and economic resource for human communities. A challenging issue in the management, conservation, and research of Pacific salmon is tracking their responses to perturbations across the multiple scales of population structure that characterize these species. Research has shown how the inherent biodiversity of Pacific salmon imparts resiliency to environmental change, and temporal stability to their overall productivity and the human systems dependent upon such productivity (e.g., fisheries). The vast biodiversity of salmon arises primarily via precise natal homing of adults to their rivers of origin, resulting in locally adapted populations. Thus, there have been considerable efforts to develop methods to effectively manage and monitor Pacific salmon biodiversity. One important example is using genetic differentiation among populations to discern the relative contributions of genetically distinct stocks in mixed stock fishery harvests. In the Bristol Bay region, sockeye salmon (O. nerka) harvests can be discerned at the watershed level (i.e., the nine major watersheds contributing to the fishery). However, tens to hundreds of locally adapted populations exist within each of these watersheds and methods to apportion fishery harvests to this finer scale population structure are lacking. This dissertation presents a new method in Alaska to discern fine-scale population structure (i.e., within watersheds) of Chinook salmon (O. tshawytscha) harvests using a naturally occurring geochemical tracer in rivers, strontium (Sr) isotopes (87Sr/86Sr). To this end, in Chapter 1, I characterize the statewide geographic variation on multiple spatial scales in 87Sr/86Sr ratios of Alaska's rivers and discuss the geochemical and geological controls of observed 87Sr/86Sr ratios. In Chapter 2, I approach the persistent problem of evaluating site-specific temporal variation, especially in remote Subarctic and Arctic regions, by employing the non-migratory behavioral ecology of slimy sculpin (Cottus cognatus). Finally, in Chapter 3, I demonstrate how the development of temporally and spatially robust 87Sr/86Sr baseline datasets within the Nushagak River was able to apportion a mixed stock fishery harvest of Chinook salmon conducted in Nushagak Bay back to natal sources at the sub-basin watershed level. Because of the conservative nature of the 87Sr/86Sr ratio during physical and biological processes, the development of this method is applicable not only to Chinook salmon, but also to other salmon species (e.g., sockeye and coho salmon, O. kisutch). Additionally, the development of baseline 87Sr/86Sr information (e.g., waters) and an overall research framework to employ this tracer in provenance studies, have statewide implications for the research and management of other migratory animals.
