Fish to 2020 by Christopher L. Delgado Pdf

The seemingly inexhaustible oceans have proved to be finite after all. Capture of wild fish have leveled off since the mid-1980s, and many stocks of fish are fished so heavily that their future is threatened. And yet the world's appetite for fish has continued to increase, particularly as urban populations and incomes grow in developing countries. Aquaculture--fish farming--has arrived to meet this increased demand. Production of fish from aquaculture has exploded in the past 20 years and continues to expand around the world. But will aquaculture be sufficient to provide affordable fish to the world over the next 20 years? And what environmental and poverty problems will aquaculture face as it expands? Using a state-of-the-art computer model of global supply and demand for food and feed commodities, this book projects the likely changes in the fisheries sector over the next two decades. As prices for most food commodities fall, fish prices are expected to rise, reflecting demand for fish that outpaces the ability of the world to supply it. The model shows that developing countries will consume and produce a much greater share of the world's fish in the future, and trade in fisheries commodities will also increase. The authors show the causes and implications of these and other changes, and argue for specific actions and policies that can improve outcomes for the poor and for the environment.

Outlook for Fish to 2020 by Delgado, Christopher L.,Wada, Nikolas,Rosegrant, Mark W.,Meijer, Siet,Ahmed, Mahfuzuddin Pdf

The seemingly inexhaustible oceans have proved to be finite after all. Landings of wild fish have leveled off since the mid-1980s, and many stocks of fish are fished so heavily that their future is threatened. And yet the world’s appetite for fish has continued to increase, particularly as urban populations and incomes grow in developing countries. Aquaculture—fish farming—has arrived to meet this increased demand. Production of fish from aquaculture has exploded in the past 20 years and continues to expand around the world. But will aquaculture be sufficient to provide affordable fish to the world over the next 20 years? And what environmental and poverty problems will aquaculture face as it expands? Using a global model of supply and demand for food and feed commodities, this report projects the likely changes in the fisheries sector over the next two decades given present trends. As prices for most food commodities fall, fish prices are expected to rise, reflecting demand for fish that outpaces the ability of the world to supply it. Alternative scenarios using different assumptions are also investigated. The model shows that developing countries will consume and produce a much greater share of the world’s fish in the future, and trade in fish commodities will also increase. As aquaculture expands, especially in developing countries, environmental concerns such as effluent pollution, escaped farmed fish, land conversion, and pressure on stocks from fishmeal demand will only increase with time unless technologies and policies promote sustainable intensification. And small, poor producers are at risk of being excluded from rapidly growing export markets unless ways can be found to facilitate affordable certification of food safety and environmentally sound production.

The Welfare of Fish by Tore S. Kristiansen,Anders Fernö,Michail A. Pavlidis,Hans van de Vis Pdf

This book investigates how fish experience their lives, their amazing senses and abilities, and how human actions impact their quality of life. The authors examine the concept of fish welfare and the scientific knowledge behind the inclusion of fish within the moral circle, and how this knowledge can change the way we treat fish in the future. In many countries fish are already protected by animal welfare legislation in the same way as mammals, but in practice there is still a major gap between how we ethically view these groups and how we actually treat them. The poor treatment of fish represents a massive animal welfare problem in aquaculture and fisheries, both in terms of the number of animals affected and the severity of the welfare issues. Thanks to its interdisciplinary scope, this thought-provoking book appeals to professionals, academics and students in the fields of animal welfare, cognition and physiology, as well as fisheries and aquaculture management.

The State of World Fisheries and Aquaculture 2020 by FAO Pdf

The 2020 edition of The State of World Fisheries and Aquaculture has a particular focus on sustainability. This reflects a number of specific considerations. First, 2020 marks the twenty-fifth anniversary of the Code of Conduct for Responsible Fisheries (the Code). Second, several Sustainable Development Goal indicators mature in 2020. Third, FAO hosted the International Symposium on Fisheries Sustainability in late 2019, and fourth, 2020 sees the finalization of specific FAO guidelines on sustainable aquaculture growth, and on social sustainability along value chains. While Part 1 retains the format of previous editions, the structure of the rest of the publication has been revised. Part 2 opens with a special section marking the twenty fifth anniversary of the Code. It also focuses on issues coming to the fore, in particular, those related to Sustainable Development Goal 14 and its indicators for which FAO is the “custodian” agency. In addition, Part 2 covers various aspects of fisheries and aquaculture sustainability. The topics discussed range widely, from data and information systems to ocean pollution, product legality, user rights and climate change adaptation. Part 3 now forms the final part of the publication, covering projections and emerging issues such as new technologies and aquaculture biosecurity. It concludes by outlining steps towards a new vision for capture fisheries. The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to-date information to a wide audience – policymakers, managers, scientists, stakeholders and indeed everyone interested in the fisheries and aquaculture sector.

World Without Fish by Mark Kurlansky Pdf

A KID’S GUIDE TO THE OCEAN "Can you imagine a world without fish? It's not as crazy as it sounds. But if we keep doing things the way we've been doing things, fish could become extinct within fifty years. So let's change the way we do things!" World Without Fish is the uniquely illustrated narrative nonfiction account—for kids—of what is happening to the world’s oceans and what they can do about it. Written by Mark Kurlansky, author of Cod, Salt, The Big Oyster, and many other books, World Without Fish has been praised as “urgent” (Publishers Weekly) and “a wonderfully fast-paced and engaging primer on the key questions surrounding fish and the sea” (Paul Greenberg, author of Four Fish). It has also been included in the New York State Expeditionary Learning English Language Arts Curriculum. Written by a master storyteller, World Without Fish connects all the dots—biology, economics, evolution, politics, climate, history, culture, food, and nutrition—in a way that kids can really understand. It describes how the fish we most commonly eat, including tuna, salmon, cod, swordfish—even anchovies— could disappear within fifty years, and the domino effect it would have: the oceans teeming with jellyfish and turning pinkish orange from algal blooms, the seabirds disappearing, then reptiles, then mammals. It describes the back-and-forth dynamic of fishermen, who are the original environmentalists, and scientists, who not that long ago considered fish an endless resource. It explains why fish farming is not the answer—and why sustainable fishing is, and how to help return the oceans to their natural ecological balance. Interwoven with the book is a twelve-page graphic novel. Each beautifully illustrated chapter opener links to the next to form a larger fictional story that perfectly complements the text.

Vanishing Fish by Daniel Pauly Pdf

"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.

Coastal Ecosystems in Transition by Thomas C. Malone,Alenka Malej,Jadran Faganeli Pdf

Explores how two coastal ecosystems are responding to the pressures of human expansion The Northern Adriatic Sea, a continental shelf ecosystem in the Northeast Mediterranean Sea, and the Chesapeake Bay, a major estuary of the mid-Atlantic coast of the United States, are semi-enclosed, river-dominated ecosystems with urbanized watersheds that support extensive industrial agriculture. Coastal Ecosystems in Transition: A Comparative Analysis of the Northern Adriatic and Chesapeake Bay presents an update of a study published two decades ago. Revisiting these two ecosystems provides an opportunity to assess changing anthropogenic pressures in the context of global climate change. The new insights can be used to inform ecosystem-based approaches to sustainable development of coastal environments. Volume highlights include: Effects of nutrient enrichment and climate-driven changes on critical coastal habitats Patterns of stratification and circulation Food web dynamics from phytoplankton to fish Nutrient cycling, water quality, and harmful algal events Causes and consequences of interannual variability The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Fish Welfare by Edward J. Branson Pdf

Fish have the same stress response and powers of nociception as mammals. Their behavioural responses to a variety of situations suggest a considerable ability for higher level neural processing – a level of consciousness equivalent perhaps to that attributed to mammals. Each chapter of this book has been written by specialists in their field. The subject matter is wide ranging and covers in detail concepts of animal welfare in addition to more specific aspects of fish welfare. Philosophical concepts of welfare are discussed along with more practical areas of fish welfare encompassing all husbandry and management activities that have a potential to affect the welfare of the fish in our care. This book is an essential purchase for fish veterinarians, fish farmers, fish biologists and those involved in the aquaculture industry and its regulation.
