All the fish in the sea
Between 1949 and 1955, the State Department pushed for an international fisheries policy grounded in maximum sustainable yield (MSY). The concept is based on a confidence that scientists can predict, theoretically, the largest catch that can be taken from a species' stock over an indefinite period. And while it was modified in 1996 with passage of the Sustained Fisheries Act, MSY is still at the heart of modern American fisheries management. As fish populations continue to crash, however, it is clear that MSY is itself not sustainable. Indeed, the concept has been widely criticized by scientists for ignoring several key factors in fisheries management and has led to the devastating collapse of many fisheries.Carmel Finley reveals that the fallibility of MSY lies at its very inception—as a tool of government rather than science. The foundational doctrine of MSY emerged at a time when the US government was using science to promote and transfer Western knowledge and technology, and to ensure that American ships and planes would have free passage through the world's seas and skies. Finley charts the history of US fisheries science using MSY as her focus, and in particular its application to halibut, tuna, and salmon fisheries. Fish populations the world over are threatened, and All the Fish in the Sea helps to sound warnings of the effect of any management policies divested from science itself.

Ocean recovery : a sustainable future for global fisheries?
\"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.\" -- Provided by publisher.

Saving global fisheries: reducing fishing capacity to promote sustainability
The Earth's oceans are overfished, despite more than fifty years of cooperation among the world's fishing nations. There are too many boats chasing too few fish. In Saving Global Fisheries, J. Samuel Barkin and Elizabeth DeSombre analyze the problem of overfishing and offer a provocative proposal for a global regulatory and policy approach.Existing patterns of international fisheries management try to limit the number of fish that can be caught while governments simultaneously subsidize increased fishing capacity, focusing on fisheries as an industry to be developed rather than on fish as a resource to be conserved. Regionally based international management means that protection in one area simply shifts fishing efforts to other species or regions. Barkin and DeSombre argue that global rather than regional regulation is necessary for successful fisheries management and emphasize the need to reduce subsidies. They propose an international system of individual transferable quotas that would give holders of permits an interest in the long-term health of fish stocks and help create a sustainable level of fishing capacity globally.

mortal sea: fishing the Atlantic in the Age of Sail
Since the time of the Vikings, the Atlantic has shaped the lives of people who depend on it for survival, and people have shaped the Atlantic. In his account of this interdependency, Bolster, a historian and professional seafarer, takes us through a millennium-long environmental history of our impact on one of the largest ecosystems in the world. Blending marine biology, ecological insight, and a remarkable cast of characters, from notable explorers to scientists to an army of unknown fishermen, Bolster tells a story that is both ecological and human: the prelude to an environmental disaster. Over generations, harvesters created a quiet catastrophe as the sea could no longer renew itself. Bolster writes in the hope that the intimate relationship humans have long had with the ocean, and the species that live within it, can be restored for future generations.

Fish
\"Fishing has played a vital role in human history and culture. But, today this key resource faces a serious crisis as most species are being overfished or fished to their very limit. Governments have tried to tackle the problem with limited success. Many of their actions have been counterproductive or ineffective. What will happen to global fisheries, and the populations that depend on them, as we continue to catch more fish than the oceans can reproduce? This book explores the causes of the current crisis in the world's fisheries, and what needs to be done to address the situation. It explains the structure of the fishing industry, the incentives that persuade individuals or companies to catch fish at unsustainable levels, and illuminates the problems created by governmental efforts to use fishing policy as a tool for economic development or to win votes in domestic elections. It also looks at the role of aquaculture in either decreasing or increasing the pressure on wild fish stocks. The dire condition of fish stocks has led governments and consumer organizations to consider new approaches to protect the global supply of fish. DeSombre and Barkin conclude by showing how such methods, along with new forms of international regulation and informed decision-making by consumers, all have an important part to play in rewarding and thus encouraging sustainable fishing behaviour in the future.\"--Pub. website.

Defining Small-Scale Fisheries and Examining the Role of Science in Shaping Perceptions of Who and What Counts: A Systematic Review
Small-scale fisheries (SSF) have long been overshadowed by the concerns and perceived importance of the industrial sector in fisheries science and policy. Yet in recent decades, attention to SSF is on the rise, marked by a proliferation of scientific publications, the emergence of new global policy tools devoted to the small-scale sector, and concerted efforts to tally the size and impacts of SSF on a global scale. Given the rising tide of interest buoying SSF, it’s pertinent to consider how the underlying definition shapes efforts to enumerate and scale up knowledge on the sector—indicating what dimensions of SSF count and consequently what gets counted. Existing studies assess how national fisheries policies define SSF, but to date, no studies systematically and empirically examine how the definition of SSF has been articulated in science, including whether and how definitions have changed over time. We systematically analyzed how SSF were defined in the peer-reviewed scientific literature drawing on a database of 1,724 articles published between 1960 and 2015. We coded a 25% random sample of articles (n=434) from our database and found that nearly one-quarter did not define SSF. Among those that did proffer a definition, harvest technologies such as fishing boats and gear were the most common characteristics used. Comparing definitions over time, we identified two notable trends over the 65-year time period studied: a decreasing proportion of articles that defined SSF and an increasing reliance on technological dimensions like boats relative to sociocultural characteristics. Our results resonate with findings from similar research on the definition of SSF in national fisheries policies that also heavily rely on boat length. We call attention to several salient issues that are obscured by an overreliance on harvest technologies in definitions of SSF, including dynamics along the wider fisheries value chain and social relations such as gender. We discuss our findings considering new policies and emerging tools that could steer scientists and practitioners toward more encompassing, consistent, and relational means of defining SSF that circumvent some of the limitations of longstanding patterns in science and policy that impinge upon sustainable and just fisheries governance.

Beyond the Tragedy in Global Fisheries
An analysis of how responsive governance has shaped the evolution of global fisheries in cyclical patterns of depletion and rebuilding dubbed the “management treadmill.”
The oceans are heavily overfished, and the greatest challenges to effective fisheries management are not technical but political and economic. In this book, D. G. Webster describes how the political economy of fisheries has evolved and highlights patterns that are linked to sustainable transitions in specific fisheries. Grounded in the concept of responsive governance, Webster's interdisciplinary analysis goes beyond the conventional view of the \"tragedy of the commons.” Using her Action Cycle/Structural Context framework, she maps long-running patterns that cycle between depletion and rebuilding in a process that she terms the management treadmill.
Webster documents the management treadmill in settings that range from small coastal fishing communities to international fisheries that span entire oceans. She identifies the profit disconnect, in which economic incentives are out of sync with sustainable use, and the power disconnect, in which those who experience the costs of overexploitation are politically marginalized. She examines how these disconnects shaped the economics of expansion and documents how political systems failed to prevent related cycles of serial resource depletion. Webster also traces the increasing use of restrictive management in response to worsening fisheries crises and the emergence of new, noncommercial interests that demand greater management but also generate substantial conflict. She finds that the management treadmill is speeding up with population growth and economic development, and so concludes that sustainable fisheries can only exist within a sustainable global economic system.
