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 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 Regional Fisheries Oceanography of the California Current System written by Sam McClatchie and published by Springer Science & Business Media. This book was released on 2013-09-30 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The California Current System is one of the best studied ocean regions of the world, and the level of oceanographic information available is perhaps only surpassed by the northeast and northwest Atlantic. The current literature (later than 1993) offers no comprehensive, integrated review of the regional fisheries oceanography of the California Current System. This volume summarizes information of more than 60-year California Cooperative Oceanic Fisheries Investigation (CalCOFI). While providing a large bibliography, the intent was to extract themes relevant to current research rather than to prepare a compendious review of the literature. The work presents a useful review and reference point for multidisciplinary fisheries scientists and biological oceanographers new to working in the California Current System, and to specialists wishing to access information outside their core areas of expertise. In addition it aims to deliver an up to date reference to the current state of knowledge of fisheries oceanography in the California Current System.

Download or read book Qualitative Modeling of Complex Systems written by Charles J. Puccia and published by . This book was released on 1985 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this modern era of mathematical modeling, applications have become increasingly complicated. As the complexity grows, it becomes more and more difficult to draw meaningful conclusions about the behavior of theoretical models and their relations to reality. Alongside methods that emphasize quantitative properties and the testing of scientific details, there is a need for approaches that are more qualitative. These techniques attempt to cover whole families of models in one bold stroke, in a manner that allows robust conclusions to be drawn about them. Loop analysis and time averaging provide a means of interpreting the properties of systems from the network of interactions within the system. The authors' methodology concentrates on graphical representation to guide experimental design, to identify sources of external variability from the statistical pattern of variables, and to make management decisions. Although most of the examples are drawn from ecology, the methods are relevant to all of the pure and applied sciences. This relevance is enhanced by case studies from such diverse areas as physiology, resource management, the behavioral sciences, and social epidemiology. The book will be useful to a broad readership from the biological and social sciences as well as the physical sciences and technology. It will interest undergraduate and graduate students along with researchers active in these disciplines. Here the reader will find a strong rationale for maintaining a holistic approach, revealing what insights and advantages are retained by the broader perspective and, more explicitly, by the synergistic effects that cannot be discerned by reducing systems to their smallest parts.
Download or read book Review of the State of World Marine Fishery Resources written by Food and Agriculture Organization of the United Nations. Marine Resources Service and published by Food & Agriculture Org.. This book was released on 1994 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.

Download or read book The Environmental Case written by Judith A. Layzer and published by CQ Press. This book was released on 2023-06-05 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Answers to environmental issues are not black and white. Debates around policy are often among those with fundamentally different values, and the way that problems and solutions are defined plays a central role in shaping how those values are translated into policy. The Environmental Case captures the real-world complexity of creating environmental policy, and this much-anticipated Sixth Edition contains 14 carefully constructed cases, including a new study of the Salton Sea crisis. Through her analysis, Sara Rinfret continues the work of Judith Layzer and explores the background, players, contributing factors, and outcomes of each case, and gives readers insight into some of the most interesting and controversial issues in U.S. environmental policymaking.
Download or read book Rights Based Fishing written by P.A. Neher and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genesis of this conference was on a quay of the port of Bergen in March 1985. Ragnar Amason suggested to Phil Neher a small, mid-Atlantic conference on recent developments in fishery management. In the event, more than twenty papers were scheduled and over one hundred and fifty conferees were registered. Logistical complications were sorted through for a summer 1988 conference in Iceland. The really innovative management programs were in the South Pacific; Aus tralia and New Zealand had introduced Individual Transferable Quotas (ITQs); and Iceland, Norway and Canada were also experimenting with quotas. It seemed to the program committee (Rognvaldur Hannesson and Geoffrey Waugh were soon on board) that these quotas had more or less characteristics of property rights. Property rights were also taking other forms in other places (time and area licenses, restrictive licensing of vessels and gear, traditional use rights). The idea of rights based fishing became the theme of the conference.
