Stories of fisheries collapse frequently grab the spotlight in the popular press. Sometimes these claims are exaggerated, sometimes not. Some species of fish have undoubtedly suffered serious decline in some areas, for example the cod stocks off New England and the Atlantic coast of Canada are now so depleted that they are close to commercial extinction. This publication attempts to provide solutions to this problem by analysing the different ways in which fish are managed around the world. It looks at the means by which individuals can be encouraged to manage marine resources sustainably, focusing on the role of institutions, conceptualised within the framework of the economics of property rights. Most commentators argue that the solution to the problems faced by the worlds fisheries is more government intervention. But the fact is that government intervention by and large caused the problem in the first place. More often than not catch levels are set and enforced by government officials who have no direct interest in ensuring the sustainability of the oceans' resources. The author is particularly critical of the European Common Fisheries Policy (CFP), which 'neatly condenses just about everything that is wrong with government management of the fisheries'. The book concludes that the prognosis for the world's fisheries is not as gloomy as many commentators have made out but nor is it as rosy as some pretend. Most likely, fisheries management will gradually evolve towards more sustainable practices. This will happen quickly if policy makers follow the precepts laid out in this publication.

Fisheries issues have been attracting increasing media attention in the wake of contamination scares, controversies over new government regulations, and environmental concerns about coastal zone management--especially the loss of wetlands, coastal erosion, pollution, and overfishing.

Scrutinizing the people, policies, institutions, and issues tied to the shrimping industry in Mississippi, Paul Durrenberger provides this first examination ever of the complexities of an American fishing industry in a single geographical area. He presents an analysis of one elaborate system--from the toils and turmoils of the people who catch the shrimp to the quandaries facing the policymakers who try to regulate them.

The shrimping industry, he contends, occurs on a series of interrelated levels and dimensions and is influenced by the ideas and actions of shrimpers, processors, fisheries managers, bureaucrats, creditors, environmentalists, and scientists. It is also one segment of a wider social, political, economic, and environmental totality.

At a local level Durrenberger investigates the impact of competition from Vietnamese refugees, rivalry between bay and gulf fishermen, an escalating overpopulation of shrimpers in general, and wide-spread resistance to costly, federally mandated devices designed to save sea turtles. Exploring how the industry is increasingly bound to the global economy, he illuminates the threat to the livelihoods of independent shrimpers from ever increasing imports.

Durrenberger assesses the adequacy of folk models of shrimpers and policymakers alike. Decisions about the industry's future, he argues, must be based on valid data and realistic expectations. Too often policies are derived from untested folk models--concepts formulated by participants to justify or rationalize rather than explain what they do.

Based on detailed interviews, Gulf Coast Soundings will be a valuable resource for anthropologists, policymakers, public administrators, resource managers, sociologists, biologists, and anyone involved or interested in the economic and environmental future of the Gulf Coast, or more generally, in fisheries and coastal areas.

Shrimpers who fish the shallow coastal waters of Texas fight a constant battle for survival--contending with shrimpers who fish the deeper gulf waters, competing with weekend sportsmen, wrangling with government regulations, and dodging environmentalists' incriminations. Add competition from the international market, an ominous threat frequently overlooked by bay fishermen, and the shrimpers; chances of winning--at least with their current lifestyle intact--are slim. In The Bay Shrimpers of Texas, Lee Maril explores the successes and failures of the shrimpers who prowl remote bays, rivers, and estuaries for their livelihoods. Through random sample surveys of fishermen, participant observation, and historical analysis, he examines the political, economic, and social realities confronting the shrimpers and their families. Legal and environmental constraints, price instability, work hazards and benefits (only one percent of the shrimpers surveyed had health insurance), rivalry with gulf and sport shrimpers, and conflict with Vietnamese refugees are all factors that affect the outlook for shrimping. Portraying the shrimpers' lives on land and water, Maril describes their boats, equipment, and various fishing strategies (both legal and illegal) used to survive in an increasingly competitive occupation. He gives an in-depth and personal look at an industry that in many ways has changed little over the last century and in others has haphazardly evolved as it enters into a ruthlessly competitive world marketplace. The prospects for bay fishing--a vital part of the cultural identity and tradition of many small coastal towns--are uncertain. By examining the past and clearing up misperceptions and myths, Maril provides valuable insight into not just the future survival or demise of one industry in a global economy, but the future of small business as a whole.

The Polar North is known to be home to large gas and oil reserves and its positionholds signifi cant trading and military advantages, yet the maritime boundaries of the region remain ill-defined. In the twenty-first century the Arctic is undergoing profound change. As the sea ice melts, a result of accelerating climate change, global governance has become vital. In this first of three volumes, the latest research and analysis from the Fridtjof Nansen Institute, the world's leading Arctic research body, is brought together. Arctic Governance: Law and Politics investigates the legal and political order of the Polar North, focusing on governance structures and the Law of the Sea. Are the current mechanisms at work effective? Are the Arctic states' interests really clashing, or is the atmosphere of a more cooperative nature? Skilfully delineating policy in the region and analysing the consequences of treaty agreements, Arctic Governance's uncovering of a rather orderly 'Arctic race' will become an indispensable contribution to contemporary International Relations concerning the Polar North.

In the nineteenth century, nearly all Native American men living along the southern New England coast made their living traveling the world's oceans on whaleships. Many were career whalemen, spending twenty years or more at sea. Their labor invigorated economically depressed reservations with vital income and led to complex and surprising connections with other Indigenous peoples, from the islands of the Pacific to the Arctic Ocean. At home, aboard ship, or around the world, Native American seafarers found themselves in a variety of situations, each with distinct racial expectations about who was ""Indian"" and how ""Indians"" behaved. Treated by their white neighbors as degraded dependents incapable of taking care of themselves, Native New Englanders nevertheless rose to positions of command at sea. They thereby complicated myths of exploration and expansion that depicted cultural encounters as the meeting of two peoples, whites and Indians. Highlighting the shifting racial ideologies that shaped the lives of these whalemen, Nancy Shoemaker shows how the category of ""Indian"" was as fluid as the whalemen were mobile.

This study analyses the Mozambique experience of protecting and promoting fisheries with an emphasis on exploring geographical indication (GI) protection for the white prawn of Mozambique. It is achieved through an in-depth review of data collected from local stakeholders, reports based on past technical support provided by the United Nations Conference on Trade and Development (UNCTAD), the literature on GIs, and international and regional treaties and reports, among others. Fishery products such as Mozambican prawns are highly recommended for GI certification, as they have high demand from both local and international consumers

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.

In general, aquaculture and fish farming cause negative impacts on the environment and wild fish populations. One of the major problems is the escape of farmed fish, especially exotic species, which can alter the population dynamics and ecology of wild stocks. Therefore, the reduction or even extinction of natural stocks may occur through predation and/or competition for resources. This book discusses the biology, behaviour and conservation strategies of both carp and catfish.

Pacific salmon are among the dominant fish groups and the main consumers of forage resources in the upper layer of the subarctic Pacific. In the last years, the majority of Pacific salmon species in North America and in Asia have experienced an increase in abundance, and their role in marine ecosystem has changed. This book examines the feeding habits and trophic status of the Pacific salmon in different regions of the subarctic Pacific under the influence of changing environmental factors. Moreover, this book deals with the present-day Norwegian regulations of saltwater salmon fisheries and particularly Norway's attempts to harmonise the interests of people and fish. Polycyclic aromatic hydrocarbons (PAH) constitute carcinogenic environmental contaminants such as dioxins. Fishes and particularly Salmonids are very sensitive to the PAH toxicity. The natural and anthropogenic PAH generations lead to an environmental contamination of water, sediments and feed of Salmonids, then to a fish contamination and finally to a human food contamination eating those contaminated fishes. The authors of this book discuss the monitoring of these chemical contaminants in salmon, essential to evaluate the pollution related to human activities and to guarantee the quality of fish as food for human consumption. In addition, the effects of replacing fish oil (FO) with rapeseed oil (RO) in Atlantic salmon post-smolt diets is discussed, and its subsequent effects on liver and muscle fatty acid (FA) composition and growth are described. This book also describes the high-pressure processing of fresh salmon and light preserved products like cold smoked salmon. Its effect on microorganisms, enzymes and organoleptic properties are analysed, as well as the process parameters, pressure, duration, and temperature affecting microorganisms, structure and colour, which all determine the market chances of the product. Moreover, the authors underline the influence of three main factors -- super-chilling, dietary lipids and pre-slaughter crowding stress, on Atlantic salmon flesh quality, with a focus on the role of lysosomes and lysosomal enzymes, cathepsins B and L, in muscle structure degradation and flesh quality.

Greenland's Inuit have for generations depended upon the hunting and sharing of whales to fulfill their needs. Yet their ability to continue their tradition in an ecologically responsible and sustainable manner is threatened by those opposed to the killing of whales. Contributions deal with various aspects of the whale hunt and the economic, social, cultural, historical, nutritional, and spiritual importance and significance of whales and whaling to Greenlandic Inuit.

December, 2014: In the forbidding waters off Antarctica, Captain Hammarstedt of the Bob Barker embarks on a voyage unlike any seen before. Across ten thousand miles of hazardous seas, Hammerstedt's crew will relentlessly pursue the Thunder - an infamous illegal fishing ship - for what will become the longest chase in maritime history. Wanted by Interpol, the Thunder has for years evaded justice: accumulating millions in profits, hunting endangered species and ruthlessly destroying ocean habitats. The authors follow this incredible expedition from the beginning. But even as seasoned journalists, they cannot anticipate what the chase will uncover, as the wake of the Thunder leads them to trail of criminal kingpins, rampant corruption, modern slavery and an international community content to turn a blind eye. Very soon, catching Thunder becomes more than a chase but a pursuit of the truth itself and a symbolic race to preserve the well-being of our planet. A Scandinavian bestseller, Catching Thunder is a remarkable true story of courage and perseverance, and a wake-up call to act against the destruction of our environments.

Before commercial whaling was outlawed in the 1980s, diplomats, scientists, bureaucrats, environmentalists, and sometimes even whalers themselves had attempted to create an international regulatory framework that would allow for a sustainable whaling industry. In "Whales and Nations," Kurkpatrick Dorsey tells the story of the international negotiation, scientific research, and industrial development behind these efforts --and their ultimate failure.

"Whales and Nations" begins in the early twentieth century, when new technology revived the fading whaling industry and made whale hunting possible on an unprecedented scale. By the 1920s, declining whale populations prompted efforts to develop "rational"--what today would be called sustainable--whaling practices. But even though almost everyone involved with commercial whaling knew that the industry was on an unsustainable path, Dorsey argues that powerful economic, political, and scientific forces made failure nearly inevitable.

Based on a deep engagement with diplomatic history, "Whales and Nations" provides a unique perspective on the challenges facing international conservation projects. This history has profound implications for today's pressing questions of global environmental cooperation and sustainability.

Kurkpatrick Dorsey is associate professor of history at the University of New Hampshire.

"This important book is essential for understanding the formation of the first global environmental agreements. It is valuable both as an argument about the failures of sustainability and as an authoritative guide to the people and issues behind the rise of global environmental awareness in the twentieth century." --Jacob Darwin Hamblin, author of "Arming Mother Nature"

""Whales and Nations" offers a fresh and timely look at the intersection of the twentieth-century whaling industry, international diplomacy, and science and is an important contribution to a topic that loomed very large in the environmental movement at a critical point in its development. It's also a great read." --Helen M. Rozwadowski, University of Connecticut, Avery Point

"The international politics of whaling underwent seismic shifts over the course of the twentieth century, reflecting complex changes in attitudes toward marine mammals and environmental protection worldwide. This important story has never been better told than in Kurkpatrick Dorsey's new book, which is likely to be the standard work on this subject for a long time to come." --William Cronon

Government management of fisheries has been little short of disastrous. In many regions, valuable fish stocks have collapsed as a result of overfishing. Ill-conceived regulation also means that every year millions of tons of edible fish are thrown back dead into the sea. While an absence of established property rights means that wild fish are vulnerable to overfishing, the problem is greatly exacerbated by large subsidies. State intervention has created significant overcapacity in the industry and undermined the economic feedback mechanisms that help to protect stocks. This short book sets out a range of policy options to improve outcomes. As well as ending counterproductive subsidies, these include community-based management of coastal zones and the introduction of individual transferable quotas. The analysis is particularly relevant to the UK as it begins the process of withdrawal from the European Union. After decades of mismanagement under the Common Fisheries Policy, Brexit represents a major opportunity to adopt an economically rational approach that benefits the fishing industry, taxpayers and consumers.

As the ice around the Arctic landmass recedes, the territory is becoming a flashpoint in world affairs. New trade routes, cutting thousands of miles off journeys, are available, and the Arctic is thought to be home to enormous gas and oil reserves. The territorial lines are new and hazy. This book looks at how Russia deals with the outside world vis a vis the Arctic. Given Russia's recent bold foreign policy interventions, these are crucial issues and the realpolitik practiced by the Russian state is essential for understanding the Arctic's future.Here, Geir Honneland brings together decades of cutting-edge research - investigating the political contexts and international tensions surrounding Russia's actions. Honneland looks specifically at 'region-building' and environmental politics of fishing and climate change, on nuclear safety and nature preservation, and also analyses the diplomatic relations surrounding clashes with Norway and Canada, as well as at the governance of the Barents Sea. The Politics of the Arctic is a crucial addition to our understanding of contemporary International Relations concerning the Polar North.

This volume is a detailed gazetteer of fish-salting production in the northwest Maghreb in antiquity. It consists of a catalogue of fish-salting sites in addition to catalogues of other related resources that are necessary for the production and trans-shipment of the industry's products: salt and amphorae kilns. The gazetteer is intended to serve as a comprehensive source book, and as such, it builds upon previous studies and current research on the region's fish-salting industry.

New England once hosted large numbers of anadromous fish, which migrate between rivers and the sea. Salmon, shad, and alewives served a variety of functions within the region's preindustrial landscape, furnishing not only maritime areas but also agricultural communities with an important source of nutrition and a valued article of rural exchange. Historian Erik Reardon argues that to protect these fish, New England's farmer-fishermen pushed for conservation measures to limit commercial fishing and industrial uses of the river. Beginning in the colonial period and continuing to the mid-nineteenth century, they advocated for fishing regulations to promote sustainable returns, compelled local millers to open their dams during seasonal fish runs, and defeated corporate proposals to erect large-scale dams. As environmentalists work to restore rivers in New England and beyond in the present day, Managing the River Commons offers important lessons about historical conservation efforts that can help guide current campaigns to remove dams and allow anadromous fish to reclaim these waters.

During the first half of the twentieth century, Canadian fisheries regularly produced more fish than markets could absorb, driving down profits and wages. To address this, both industry and government sought to stimulate domestic consumption via increased advertising. In Eating the Ocean Brian Payne explores how government-funded marketing called upon Canadian housewives to prepare more seafood meals to improve family health and aid an industry central to Canadian identity and heritage. The goal was first to make seafood a central element of a "wholesome" diet as a solution to a perceived nutritional crisis, and, second, to aid industry recovery and growth while decreasing Canadian fisheries' dependency on foreign markets. But fishery managers and policymakers fundamentally miscalculated consumer demand, wrongly assuming that Canadians could and would eat more seafood. Fisheries continued to extract more fish than the environment and the market could sustain, and the collapse of the nation's fisheries that we are now seeing has as much to do with failed assessments of market demand as it does with faulty extraction practices. Using internal communications between industry leaders and Ottawa bureaucrats, as well as advertising and promotional material published in the nation's leading magazines, national and local newspapers, and radio programming, Eating the Ocean traces the flawed understanding of not only supply but demand, a misguided gamble that caused fisheries to become the most mismanaged resource economy in early-twentieth-century Canada.

The sea and its relation to human life has always been a subject of fascination for historians. For the first time, this book looks at the field of Maritime History through the prism of identity, looking at how the sea has influenced the formation of identity at a national, local and individual level from the early modern age to the present. It looks at a variety of people who interacted with the sea in different ways, from merchant sailors to naval officers and on land, from dockworkers to the civilians who participated in the sea-based festivals in the Mediterranean port city of Messina. This volume has a cultural focus, with chapters exploring the cultural construction of the 'naval hero' in literature, poetry, music and art, and an appraisal of the Japanese author and journalist Masanori, whose works had such a profound influence on Japanese national identity after the Second World War. A key focus is on the ways the Royal Navy influenced British identity at a national and regional level, but this volume also explores other countries with a strong naval tradition, such as Japan, Italy and Germany. By bringing together a variety of themes related to identity, this book provides the first attempt to thoroughly analyse the ways in which maritime historians have engaged with the question of identity in recent years. In doing so, it provides an important and unique addition to the historiography, which will be essential reading for all scholars of maritime and naval history and those concerned with the question of identity.

Focusing on the internal workings of the International Whaling Commission (IWC), the author explores the impact of political and economic imperatives on the production and interpretation of scientific research. Central to this work are the epistemological problems encountered in the production of 'truth', whereby scientific knowledge has made uncertainty a tool in the service of political objectives.

In 2006 Congress recognised the need for international cooperation to address some of the most significant issues affecting international fisheries today: illegal, unreported, and unregulated (IUU) fishing and fishing practices that may undermine the sustainability of living marine resources. In 2010, Congress focused on the need for enhanced international action to conserve and protect sharks in passing the Shark Conservation Act. By requirement, the Secretary of Commerce, in biennial reports, is to identify nations whose fishing vessels are engaged in certain IUU fishing, bycatch, and shark fishing practices; describe U.S. consultations with the identified countries to urge appropriate actions; and certify whether such actions subsequent to identification have adequately addressed the offending activities. The Secretary of Commerce has delegated authority to identify and certify countries under the Moratorium Protection Act to the NOAA Assistant Administrator for Fisheries. The Secretary of Commerce is also directed, in consultation with the Secretary of State and in cooperation with relevant regional fishery management councils and any relevant advisory committees, to take certain actions to improve the effectiveness of international fishery management organizations in conserving and managing stocks under their jurisdiction. This book surveys efforts by the United States to strengthen its leadership toward improving international fisheries management and enforcement, particularly with regard to IUU fishing, bycatch of protected living marine resources (PLMRs), and certain shark fishing practices. Furthermore, this book covers issues that have been identified during congressional hearings and in legislation introduced during the last three Congresses, some of which include the flexibility in rebuilding overfished fisheries; annual catch limits; uncertainty and data needs; catch shares (limited access privilege programs); management process and decision making; bycatch; and environmental quality.

In the last decades, the human harvesting of marine resources became more efficient as the understanding of the habits and behaviours of the various species available in the sea gradually increased. Technologies naturally developed over time and fishing systems became more sophisticated and increasingly adapted to catch the most desirable species and sizes. This evolution is still in progress and technological development goes on especially in the Mediterranean area, where small and relatively old fishing vessels are traditionally used. These technical advances in fishing gears have generally led to more efficient fishing operations and improved access to resources and fishing grounds. On the other hand, general awareness on the environmental problems due to the exploitation of fisheries resources has also increased. Therefore, in order to preserve fishery resources and marine environments, fishing gears and their impacts need to be further investigated and less impacting techniques should be developed. In this regard, fishing technologists are responsible to provide fishery managers as well as fishermen and stakeholders, with useful advice and technical solutions for mitigating adverse impacts of fishing gears. By taking these problems into account, the book contents are based on the requirements of ecosystem-approach to fisheries management. The Code of Conduct for Responsible Fisheries of the FAO (1995) encouraged the use of selective, environmentally safe and cost effective gear and techniques. Thus the book aims at providing information on sustainable fishing technologies, and transfers the expertise on fishing technology to Mediterranean fisheries scientists and end-users such as fisheries managers, administrators, controllers etc. This book is structured to provide information on fishing gear technology, selectivity, bycatch-impact reduction and fishing vessel technology, with particular attention to the Mediterranean context. The information included might be used to learn how to assess the impacts and selectivity of different fishing gears and find technical solutions to mitigate these impacts and to address scientific studies. Furthermore, advices on the properties of fishing vessels affecting energy efficiency have been also considered in order to address possible technical changes to the currents boats. Finally the contents of this book might be considered as a useful tool when preparing management measures as well as for the establishment, enforcement or improvement of fishing rules.
