Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-02-19 with total page 188 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 Effects of Fishing on Marine Ecosystems and Communities written by Stephen Hall and published by Wiley-Blackwell. This book was released on 1999-03-19 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over-exploitation of the world's fish resources receives considerable attention and is a source of justifiable concern. However, fishing does much more than simply remove the species of interest. What are the other problems that fishing might cause? Are there knock-on effects caused by removal of the target species for other parts of the system? What incidental damage does fishing cause and how much do we really know and understand about the consequences of our actions? The Effects of Fishing on Marine Ecosystems and Communitites draws together, within one volume, an expert and comprehensive assessment of the problem.
Download or read book Mismanagement of Marine Fisheries written by Alan Longhurst and published by Cambridge University Press. This book was released on 2010-04-22 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Longhurst examines the proposition, central to fisheries science, that a fishery creates its own natural resource by the compensatory growth it induces in the fish, and that this is sustainable. His novel analysis of the reproductive ecology of bony fish of cooler seas offers some support for this, but a review of fisheries past and present confirms that sustainability is rarely achieved. The relatively open structure and strong variability of marine ecosystems is discussed in relation to the reliability of resources used by the industrial-level fishing that became globalised during the 20th century. This was associated with an extraordinary lack of regulation in most seas, and a widespread avoidance of regulation where it did exist. Sustained fisheries can only be expected where social conditions permit strict regulation and where politicians have no personal interest in outcomes despite current enthusiasm for ecosystem-based approaches or for transferable property rights.
Download or read book Effects of Fishing on Non Target Species and Habitats written by Michael J. Kaiser and published by Wiley-Blackwell. This book was released on 2000-01-21 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing is a major form of ecological disturbance to marine communities throughout the world. In the past, fisheries biologists have concentrated on the studying of the direct effects of fishing on stocks of target species and understanding the processes of recruitment. There is now a growing appreciation of the ecological implications of the wider effects of fishing activities on marine organisms and their habitats. Contributions include articles that consider the physical effects of fishing gears on the seabed; distribution of, and trends in fishing effort; ecological effects on benthic fauna; long-term community changes; the effects of food subsidies in the marine environment; interactions between fisheries and marine mammals; technical measures to reduce impacts of fisheries; conservation issues and priorities; socio-economic implications of wider fisheries impacts.
Download or read book Ocean Recovery written by Ray Hilborn and published by Oxford University Press. This book was released on 2019-06-27 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last two decades, the scientific and popular media have been bombarded by gloom and doom stories of the future of fisheries, the status of fish stocks, and the impact of fishing on marine ecosystems. Dozens of certification and labeling schemes have emerged to advise consumers on what seafood is sustainable. In recent years, an opposing narrative has emerged emphasizing the success of fisheries management in many places, the increasing abundance of fish stocks in those places, and the prescription for sustainable fisheries. However, there has been no comprehensive survey of what really constitutes sustainability in fisheries, fish stock status, success and failures of management, and consideration of the impacts of fishing on marine ecosystems. This book will explore very different perspectives on sustainability, and bring together the data from a large number of studies to show where fish stocks are increasing, where they are declining, the consequences of alternative fisheries management regimes, and what is known about a range of fisheries issues such as the impacts of trawling on marine ecosystems. Ocean Recovery is aimed principally at a general audience that is already interested in fisheries but seeks both a deeper understanding of what is known about specific issues and an impartial presentation of all the data rather than selected examples used to justify a particular perspective or agenda. It will also appeal to the scientific community eager to know more about marine fisheries and fishing data, and serve as the basis for graduate seminars on the sustainability of natural resources.

Available in PDF, EPUB and Kindle. Book excerpt: Most of the major impacts of fishing on the ecosystems recorded around the world occur in the Mediterranean. This variety of interactions is due to four main interrelated factors: the wide range of fishing gear and practices; very intensive fishing; a high diversity of exploited habitats, ranging from shallow water to the deep-sea and oceanic domain; and high biological diversity.
Download or read book The Economic Effects of COVID 19 Containment Measures written by Pragyan Deb and published by . This book was released on 2020-08-07 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containment measures are crucial to halt the spread of the 2019 COVID-19 pandemic but entail large short-term economic costs. This paper tries to quantify these effects using daily global data on real-time containment measures and indicators of economic activity such as Nitrogen Dioxide (NO2) emissions, flights, energy consumption, maritime trade, and mobility indices. Results suggest that containment measures have had, on average, a very large impact on economic activity--equivalent to a loss of about 15 percent in industrial production over a 30-day period following their implementation. Using novel data on fiscal and monetary policy measures used in response to the crisis, we find that these policy measures were effective in mitigating some of these economic costs. We also find that while workplace closures and stay-at-home orders are more effective in curbing infections, they are associated with the largest economic costs. Finally, while easing of containment measures has led to a pickup in economic activity, the effect has been lower (in absolute value) than that from the tightening of measures.
Download or read book Environmental Protection Critical Perspectives in Science and Literature written by Dr. Mallesh Reddy and published by tredition. This book was released on 2021-03-02 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book investigates various dimensions of environmental protection and degradation. It contain original and review research articles from science as well as literature fields. Broadly speaking it covers the areas like environmental degradation, issues of pollution, geo-environmental predicament, Eco criticism and environmental consciousness in English literature. The main purpose of the book is to investigate present predicament of environmental degradation and to discuss the possible solutions in a scientific way for the protection of environment. At present the books available on the topic of environmental protection does not cover all the dimensions and most of them are particular path oriented like resources on biodiversity, pollution, etc. the present book fulfils this lacuna and explores environment from various perspectives in a scientific way. The book also discusses reflection of environmental consciousness in literature. Since environmental degradation and protection is a multi-layered phenomenon, this book will be helpful to the teachers, students and researchers who wish to understand various dimensions of the environmental issues with possible scientific solutions.
Download or read book Overfishing written by Ray Hilborn and published by Oxford University Press. This book was released on 2012-04-06 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past twenty years considerable public attention has been focused on the decline of marine fisheries, the sustainability of world fish production, and the impacts of fishing on marine ecosystems. Many have voiced their concerns about marine conservation, as well as the sustainable and ethical consumption of fish. But are fisheries in danger of collapse? Will we soon need to find ways to replace this food system? Should we be worried that we could be fishing certain species to extinction? Can commercial fishing be carried out in a sustainable way? While overblown prognoses concerning the dire state of fisheries are plentiful, clear scientific explanations of the basic issues surrounding overfishing are less so - and there remains great confusion about the actual amount of overfishing and its ecological impact. Overfishing: What Everyone Needs to Know® will provide a balanced explanation of the broad issues associated with overfishing. Guiding readers through the scientific, political, economic, and ethical issues associated with harvesting fish from the ocean, it will provide answers to questions about which fisheries are sustainably managed and which are not. Ray and Ulrike Hilborn address topics including historical overfishing, high seas fisheries, recreational fisheries, illegal fishing, climate and fisheries, trawling, economic and biological overfishing, and marine protected areas. In order to illustrate the effects of each of these issues, they will incorporate case studies of different species of fish. Overall, the authors present a hopeful view of the future of fisheries. Most of the world's fisheries are not overfished, and many once overfished stocks are now rebuilding. In fact, we can learn from the management failures and successes to ensure that fisheries are sustainable and contribute to national wealth and food security. Concise and clear, this book presents a compelling "big picture" of the state of oceans and the solutions to ending overfishing.

Download or read book Commerical Fishing written by G. Moore and published by Wiley-Blackwell. This book was released on 2000-05-18 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fishing provides food, income and employment for millions of people. However, fishing has environmental costs that threaten rare species, marine ecosystems and the sustainability of the resource. Based on the research expertise of leading scientists, Commercial Fishing: the Wider Ecological Impacts provides a lively, timely and accessible account of fishing activities and their impacts on marine habitats, biodiversity and species of conservation concern. It covers fishing methods that range from trawling in the Antarctic to fishing with dynamite in the tropics. The authors show how habitats such as the muddy sea beds of the deep sea, kelp forests and coral reefs are affected by fishing and how birds, mammals, turtles and sea snakes both suffer and benefit from fishing activities. They also look to the future, highlighting ways to make fishing gear 'environmentally friendly' and asking whether marine reserves will improve conservation.

Book excerpt: "Daniel Pauly is a friend whose work has inspired me for years." —Ted Danson, actor, ocean activist, and co-author of Oceana "This wonderfully personal and accessible book by the world’s greatest living fisheries biologist summarizes and expands on the causes of collapse and the essential actions that will be required to rebuild fish stocks for future generations.” —Dr. Jeremy Jackson, ocean scientist and author of Breakpoint The world’s fisheries are in crisis. Their catches are declining, and the stocks of key species, such as cod and bluefin tuna, are but a small fraction of their previous abundance, while others have been overfished almost to extinction. The oceans are depleted and the commercial fishing industry increasingly depends on subsidies to remain afloat. In these essays, award-winning biologist Dr. Daniel Pauly offers a thought-provoking look at the state of today’s global fisheries—and a radical way to turn it around. Starting with the rapid expansion that followed World War II, he traces the arc of the fishing industry’s ensuing demise, offering insights into how and why it has failed. With clear, convincing prose, Dr. Pauly draws on decades of research to provide an up-to-date assessment of ocean health and an analysis of the issues that have contributed to the current crisis, including globalization, massive underreporting of catch, and the phenomenon of “shifting baselines,” in which, over time, important knowledge is lost about the state of the natural world. Finally, Vanishing Fish provides practical recommendations for a way forward—a vision of a vibrant future where small-scale fisheries can supply the majority of the world’s fish.
