This book was released on 2017 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Skates are common bottom-dwelling fishes and valuable non-target species in Gulf of Alaska fisheries. Although there is little demand for skates in the United States, markets in Europe and Asia are fueling desires for additional fishing opportunities on skates in Alaska. Management agencies, however, have been hesitant to allow increased harvests due to the lack of information on the ecology and population dynamics of skates, and the bioeconomics of skate fisheries. Specifically focusing on the two most commonly landedskate species in the Gulf of Alaska (GOA), the big skate (Beringraja binoculata) and the longnose skate (Raja rhina), I conducted an interdisciplinary project to address these knowledge gaps. First, I advanced our understanding of the movement patterns and habitat use of skates by satellite tagging big skates in the GOA. The results show that big skates can, and likely frequently do, travel long distances, cross management boundaries within the GOA, and spend more time in deeper waters than previously thought. Second, I used the insights from the movement study to develop the first stock assessment models for skates in the GOA. This represents an important improvement in modeling, laying the groundwork for the North Pacific Fishery Management Council to move from Tier 5 (more data limited) to Tier 3 (less data limited) harvest control rules, which should lead to increased confidence with which the total allowable catch (TAC) for skates is set. Finally, I used the sustainable harvest estimates from the stock assessment models to develop a model that examined the impacts of management decisions on the profitability of skate fishing. My research provides essential information about these understudied fishes, helping to improve the sustainability and profitability of skate harvests. Incorporation of best available science regarding skate ecology, population dynamics, and bioeconomics into fishery management fosters more responsible development of skate fisheries, sustainable fishery revenues, and employment, and reduces the risk of overfishing, stock collapse, and prolonged fishery closures. It is my hope that fishery management agencies and the fishing industry make use of the new information and insights presented in this dissertation to work collaboratively towards the responsible development of skate fisheries.

This book was released on 2018-12-16 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Law Library presents the complete text of the Fisheries of the Exclusive Economic Zone Off Alaska - Revise Maximum Retainable Amounts for Skates in the Gulf of Alaska (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 NMFS issues regulations to reduce the maximum retainable amount (MRA) of skates using groundfish and halibut as basis species in the Gulf of Alaska (GOA) from 20 percent to 5 percent. Reducing skate MRAs is necessary to decrease the incentive for fishermen to target skates and slow the catch rate of skates in these fisheries. This final rule will enhance conservation and management of skates and minimize skate discards in GOA groundfish and halibut fisheries. This final rule is intended to promote the goals and objectives of the Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens Act), the Fishery Management Plan for Groundfish of the Gulf of Alaska (FMP), and other applicable laws. This ebook contains: - The complete text of the Fisheries of the Exclusive Economic Zone Off Alaska - Revise Maximum Retainable Amounts for Skates in the Gulf of Alaska (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure
Download or read book Improving Fish Stock Assessments written by National Research Council and published by National Academies Press. This book was released on 1998-02-27 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean harvests have plateaued worldwide and many important commercial stocks have been depleted. This has caused great concern among scientists, fishery managers, the fishing community, and the public. This book evaluates the major models used for estimating the size and structure of marine fish populations (stock assessments) and changes in populations over time. It demonstrates how problems that may occur in fisheries dataâ€"for example underreporting or changes in the likelihood that fish can be caught with a given type of gearâ€"can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Download or read book Sea Change written by National Research Council and published by National Academies Press. This book was released on 2015-05-19 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ocean science connects a global community of scientists in many disciplines - physics, chemistry, biology, geology and geophysics. New observational and computational technologies are transforming the ability of scientists to study the global ocean with a more integrated and dynamic approach. This enhanced understanding of the ocean is becoming ever more important in an economically and geopolitically connected world, and contributes vital information to policy and decision makers charged with addressing societal interests in the ocean. Science provides the knowledge necessary to realize the benefits and manage the risks of the ocean. Comprehensive understanding of the global ocean is fundamental to forecasting and managing risks from severe storms, adapting to the impacts of climate change, and managing ocean resources. In the United States, the National Science Foundation (NSF) is the primary funder of the basic research which underlies advances in our understanding of the ocean. Sea Change addresses the strategic investments necessary at NSF to ensure a robust ocean scientific enterprise over the next decade. This survey provides guidance from the ocean sciences community on research and facilities priorities for the coming decade and makes recommendations for funding priorities.

Available in PDF, EPUB and Kindle. Book excerpt: "The International Council for the Exploration of the Sea (ICES) is the central scientific network within the massive set of bureaucracies that is responsible for Europe's Common Fisheries Policy (CFP). While spending the past 25 years failing to sustain Europe's fish stocks, this management system also became adept at making the lives of its scientists miserable. Now it is being confronted by the complex challenge of an ecosystem-based approach to fisheries management. If this combination of a multi-national bureaucracy, hard politics, and scientific uncertainty has made it impossible to maintain many individual fish stocks, how are decisions going to be made that consider everything from sea birds to climate change? The old political saw that "if you can't solve a problem, make it bigger" has never been put to a test like this! Yet ICES has begun to rise in an impressive way to the scientific challenge of providing advice for an ecosystem approach within the world's most cumbersome fisheries management system. This book lays out the results of extensive sociological research on ICES and the decision making systems into which it feeds. ICES is finding ways to provide effective advice in the many situations where scientific advice is needed but a clear, simple answer is out of reach. In spite of the difficulties, scientists are beginning to help the various parties concerned with management to deal with facts about nature in ways that are more useful and transparent"--Publisher's description.

Download or read book Ecosystem Based Fisheries Management written by Jason Link and published by Cambridge University Press. This book was released on 2010-10-07 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Responsible fisheries management is of increasing interest to the scientific community, resource managers, policy makers, stakeholders and the general public. Focusing solely on managing one species of fish stock at a time has become less of a viable option in addressing the problem. Incorporating more holistic considerations into fisheries management by addressing the trade-offs among the range of issues involved, such as ecological principles, legal mandates and the interests of stakeholders, will hopefully challenge and shift the perception that doing ecosystem-based fisheries management is unfeasible. Demonstrating that EBFM is in fact feasible will have widespread impact, both in US and international waters. Using case studies, underlying philosophies and analytical approaches, this book brings together a range of interdisciplinary topics surrounding EBFM and considers these simultaneously, with an aim to provide tools for successful implementation and to further the debate on EBFM, ultimately hoping to foster enhanced living marine resource management.
