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.
Download or read book Management Systems for Riverine Fisheries written by Thayer Scudder and published by Food & Agriculture Org.. This book was released on 1985 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned specifically with the problems of river fisheries and associated management issues. It deals in particular with the scope for building on traditional practices, through the participation of traditional fishing communities, as a means of improving the quality of river fishery management. The paper reviews the most frequently encountered problems of riverine fisheries such as over-fishing due to population pressure or migration, and artifically induced environmental factors such as dams, pollution and deforestation. It lays stress on the importance of studying fishing communities, as well as strictly biological factors, and presents a four-stage analysis of the evolution of traditional riverine fisheries. Several undesirable consequences of this typical evolution, both on the resource itself and on traditional fishing communities, are identified and illustrated by case studies from the Amazon and the Zambesi. Certain types of traditional management strategies are examined and assessed for their future utility. The current ineffectiveness of many existing government river fisheries management policies is noted, either as a result of lack of resources or because they are inappropriate, often rooted in outdated colonial legislation. The lack of both limited access measures and of participation by local fishing communities are highlighted as major deficiencies. The paper concludes by linking these two features as crucial components of durable river management strategies for the future, although other possibilities for management are also reviewed and assessed. The paper contains a comprehensive bibliography for further reading.

Download or read book Fish Markets and Fishermen written by Suzanne Iudicello and published by Island Press. This book was released on 2012-06-22 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: A significant number of the world's ocean fisheries are depleted, and some have collapsed, from overfishing. Although many of the same fishermen who are causing these declines stand to suffer the most from them, they continue to overfish. Why is this happening? What can be done to solve the problem. The authors of Fish, Markets, and Fishermen argue that the reasons are primarily economic, and that overfishing is an inevitable consequence of the current sets of incentives facing ocean fishermen. This volume illuminates these incentives as they operate both in the aggregate and at the level of day-to-day decision-making by vessel skippers. The authors provide a primer on fish population biology and the economics of fisheries under various access regimes, and use that information in analyzing policies for managing fisheries. The book: provides a concise statistical overview of the world's fisheries documents the decline of fisheries worldwide gives the reader a clear understanding of the economics and population biology of fish examines the management issues associated with regulating fisheries offers case studies of fisheries under different management regimes examines and compares the consequences of various regimes and considers the implications for policy making The decline of the world's ocean fisheries is of enormous worldwide significance, from both economic and environmental perspectives. This book clearly explains for the nonspecialist the complicated problem of overfishing. It represents a basic resource for fishery managers and others-fishers, policymakers, conservationists, the fish consuming public, students, and researchers-concerned with the dynamics of fisheries and their sustenance.
Download or read book Voluntary Guidelines for Securing Sustainable Small Scale Fisheries in the Context of Food Security and Poverty Eradication written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-11-16 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the Context of Food Security and Poverty Eradication (SSF Guidelines) represent the first ever international instrument dedicated to small-scale fisheries. They represent a global consensus on principles and guidance for small-scale fisheries governance and development. They were developed for small-scale fisheries in close collaboration with representatives of small-scale fisheries organizations in a participatory process between 2011-13, involving over 4000 stakeholders; facilitated by FAO, based on a mandate by COFI. They are directed at all those involved in the sector and intend to guide and encourage governments, fishing communities and other stakeholders to work together and ensure secure and sustainable small-scale fisheries for the benefit of small-scale fishers, fish workers and their communities as well as for society at large.
Download or read book Evolving Approaches to Managing Marine Recreational Fisheries written by Donald Leal and published by Lexington Books. This book was released on 2009 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Increasing coastal populations, rising recreational demand, and growing conflicts with other users are adding to the challenge of managing marine recreational fisheries today. Traditional regulations - such as daily bag limits and seasonal closures - are often not enough to control fishing impacts and they tend to generate greater discontent and lower economic benefits in the angling community as they become more restrictive. This volume is the first to examine management approaches that promise to better control fishing, generate more information on fishing impacts, and give anglers more freedom to enjoy their sport."--BOOK JACKET.
Download or read book The Sunken Billions written by World Bank and published by World Bank Publications. This book was released on 2009-02-25 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'The Sunken Billions: The Economic Justification for Fisheries Reform' shows the difference between the potential and actual net economic benefits from marine fisheries is about $50 billion per year, or some $2 trillion over the last three decades. If fish stocks were rebuilt, the current marine catch could be achieved with approximately half the current global fishing effort. This illustrates the massive overcapacity of the global fleet. The excess competition for the limited fish resources results in declining productivity, economic inefficiency, and depressed fisher incomes. The focus on the deteriorating biological health of world fisheries has tended to obscure their equally critical economic health. Achieving sustainable fisheries presents challenges not only of biology and ecology, but also of managing political and economic processes and replacing pernicious incentives with those that foster improved governance and responsible stewardship. Improved governance of marine fisheries could regain a substantial part of this annual economic loss and contribute to economic growth. Fisheries governance reform is a long-term process requiring political will and consensus vision, built through broad stakeholder dialogue. Reforms will require investment in good governance, including strengthening marine tenure systems and reducing illegal fishing and harmful subsidies. Realizing the potential economic benefits of fisheries means reducing fishing effort and capacity. To offset the associated social adjustment costs, successful reforms should provide for social safety nets and alternative economic opportunities for affected communities.

Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.

Available in PDF, EPUB and Kindle. Book excerpt: "Sustainable use of aquatic ecosystems is high on regional, national and international agendas and central to the implementation of international agreements on biological diversity, responsible fisheries and fish stock management. Since 2001, when political commitments were made to implement the ecosystem approach, countries have begun to incorporate ecosystem considerations into their fisheries management and have met with varied success." "The Ecosystem Approach to Fisheries covers both theoretical andapplied aspects of sustainable management, with a particular emphasis on reviewing concepts and addressing implementation issues in the form of case studies from around the world. Personal experiences are considered from diverse backgrounds and discuss the constraints encountered, strategies identified and best practices to facilitate further implementation."--BOOK JACKET.
Download or read book Alternative Arrangements for Marine Fisheries written by Francis T. Christy, Jr. and published by Routledge. This book was released on 2015-08-11 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The maintenance of the freedom of fishing in the face of the changing circumstances that were occurring at the time of this title’s original publication in 1973 had produced several damaging consequences. It had led to considerable waste, in both biological and economic terms, and had been the source of increasing conflict. This waste can only be prevented by the adoption of management measures and by the removal of the condition of free and open access. This book explores various techniques for this, and will be of interest to students of environmental management.

Download or read book Improving Fish Stock Assessments written by Committee on Fish Stock Assessment Methods and published by National Academies Press. This book was released on 1998-03-13 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 data--for example underreporting or changes in the likelihood that fish can be caught with a given type of gear--can seriously degrade the quality of stock assessments. The volume makes recommendations for means to improve stock assessments and their use in fishery management.

Book excerpt: Although the United States and other affluent nations havemore than an adequate food supply, other nations daily facethe specter of starvation. The world now has a critical population/food dilemma of potentially major proportions. Production fromthe sea and the land is not keeping pace with a world populationthat is doubling every thirty-five years. Unless this age-oldMalthusian problem is solved, millions face starvation and ultimatelydeath.The situation has stimulated substantial international interestin the sea as a source of food and raw materials. The potentialof the sea-not as a panacea, but as an important source of proteinto augment the world's food supplies and thereby as a meansof mitigating the crises we face-is a continuing theme throughoutthis book. At present, fish provide approximately 9 percentof the world's protein. Fish are sought not only for food butalso for recreation and pleasure. What forces determine the presentsupply and demand for fishery products? More important,what steps are needed to utilize the full potential of the sea asa source of food and recreation? This book explores these forcesand thus provides an insight into food potential from the sea.
