Book Description
The World Ocean Assessment - or, to give its full title, The First Global Integrated Marine Assessment - is the outcome of the first cycle of the United Nations' Regular Process for Global Reporting and Assessment of the State of the Marine Environment, including Socioeconomic Aspects. The Assessment provides vital, scientifically-grounded bases for the consideration of ocean issues, including climate change, by governments, intergovernmental agencies, non-governmental agencies and all other stakeholders and policymakers involved in ocean affairs. Together with future assessments and related initiatives, it will support the implementation of the recently adopted 2030 Agenda for Sustainable Development, particularly its ocean-related goals. Moreover, it will also form an important reference text for marine science courses.

Book Description
This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment.Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.

Book Description
Fisheries for highly migratory species are important in all oceans and semi-enclosed seas, except for polar regions. Fisheries for straddling fish stocks are much more localised, primarily occurring in a few regions where continental shelves extend beyond the 200 miles Exclusive Economic Zone (EEZ), while most fisheries for other high seas fishery resources are deep-water fisheries. This publication examines issues relating to the stocks of these resources, including information on their state of exploitation. Findings include that about 30 percent of the stocks of highly migratory tuna and tuna-like species, more than half of highly migratory oceanic sharks and nearly two-thirds of the straddling stocks and the stocks of other high seas fishery resources are overexploited or depleted. Although the stocks concerned represent only a small fraction of the world fishery resources, they are key indicators of the state of an overwhelming part of the ocean ecosystem which appears to be more overexploited than EEZs.

Book Description
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.

Book Description
Fisheries and Aquaculture theme is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Fisheries are a major life support system and the main purpose of this theme on Fisheries and Aquaculture is to provide baseline information and latest knowledge at the dawn of this century to facilitate vital fisheries recovery before their irreparable collapse. This Theme on Fisheries and Aquaculture is divided into five topics. It starts with discussions on major issues and challenges in “Harvesting the Seas”, with emphasis on the role and importance of the fisheries sector and its environment, and introduces trends and perspectives in marine fisheries, including allocation of use rights, subsidies, and port management. The next two topics present an in-depth and detailed knowledge on fish and other aquatic living resources that are commercially exploited and/or farmed. The third topic on Inland Fisheries presents salmonid fish, eels, shad, whitefish and smelt, carp, perch, pike and bass, tilapia, frog, and crustaceans. The fourth topic presents a comprehensive review of trends and perspectives in Aquaculture: Principles and Prospects. The fifth topic on Economics of Fisheries and Aquaculture reviews the latest views and concepts useful to apprehend the fisheries management regime, including a comparative static economic theory and a dynamic theory of fishery, spatial bioeconomic dynamics and role of international law in the management of marine fisheries, rights-based and community fisheries management, aquaculture economics, and game theory and fisheries. These five volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.

Book Description
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.
