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 Rebuilding of Marine Fisheries Global review written by Serge Garcia and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Rebuilding depleted stocks is a central part of the fisheries governance agenda. By analysing the available literature, Part 1 of "Rebuilding of marine fisheries" provides a global review of the emergence of the rebuilding paradigm, its key concepts, the trends in fishery resources, and the empirical evidence available on stocks depletion, collapse and rebuilding. It addresses the bio-ecological, economic, and human dimensions of rebuilding or restoration of stocks, multispecies assemblages and habitats/ecosystems and touches on the need for rebuilding at the whole sector level when depletion has become widespread and chronic. The human imensions of stocks and fisheries are given particular attention, looking at conflicting objectives, the bio-economy of rebuilding, its costs and benefits, and the distributional effects of the related reform among actors with their potential social consequences in the short and long terms. Governance is addressed in detail: legal and policy frameworks; rationale and objectives of a rebuilding regime; alternative rebuilding strategies; reference values and protocols; regulatory time-frames; risk management and harvest control rules; impacts of climatic oscillations; management tool-box; implementation guidance and performance evaluation. The document ends with a review of the determinants of success of a rebuilding programme."--Publisher's description for part 1.

Download or read book Comparative Evaluations of Innovative Fisheries Management written by Kjellrun Hiis Hauge and published by Springer Science & Business Media. This book was released on 2009-09-23 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comparative Evaluations of Innovative Fisheries Management begins with a look at four places outside the European Union known for innovative management: New Zealand, Nova Scotia, Alaska and Iceland. Then the focus shifts to the success criteria related to specific disciplines including biological and social robustness, economic efficiency and impacts on management costs. Hypotheses are tested using data capable of generating useful results. The main conclusions include a retrospective of how key concepts defined and represented the various perspectives, skills and backgrounds that made up the multidisciplinary CEVIS project.

This book was released on 2007 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on a number of case studies from around the world, this publication considers how the local knowledge and practices of indigenous fishing communities are being used in collaboration with scientists, government managers and non-governmental organisations to establish effective frameworks for sustainable fisheries science and management. It seeks to contribute towards achieving the goal of establishing international responsibility for the ethical collection, preservation, dissemination and application of fishers' knowledge.
Download or read book The Precautionary Principle in the 20th Century written by Paul Harremoes and published by Routledge. This book was released on 2013-10-11 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The precautionary principle is widely seen as fundamental to successful policies for sustainability. It has been cited in international courts and trade disputes between the USA and the EU, and invoked in a growing range of political debates. Understanding what it can and cannot achieve is therefore crucial. This volume looks back over the last century to examine the role the principle played or could have played, in a range of major and avoidable public disasters. From detailed investigation of how each disaster unfolded, what the impacts were and what measures were adopted, the authors draw lessons and establish criteria that could help to minimise the health and environmental risks of future technological, economic and policy innovations. This is an informative resource for all those from lawyers and policy-makers, to researchers and students needing to understand or apply the principle.

Download or read book Gene Drives on the Horizon written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
