Available in PDF, EPUB and Kindle. Book excerpt: A changing environment is not a new challenge for Pacific salmon. This group of fishes has proven resilient, persisting over millions of years while surviving massive changes in climate and physical habitats. There is therefore reason to believe that salmon will be able to adapt to the changes anticipated in association with global climate change. Indeed, the level of warming predicted for the coming century seems a surmountable challenge for salmon at the genus level. However, climate change is impacting and will continue to impact individual populations, driving marked changes in their ecology, abundance and life-histories. The distinction between species and population is important because the majority of ecological, cultural and economic values provided by salmon are manifest at local or regional scales and tied to specific populations, species and life-history types. Furthermore, it is typically at these scales that fisheries and fish habitats are managed. Although the influence of past climate variability on the productivity of salmon populations demonstrates sensitivity of these species to environmental change, unanticipated and unintuitive outcomes are possible given the complexity and diversity of the species and their life-histories. Understanding past variability and predicting future trajectories of salmon populations therefore requires an in-depth understanding of the mechanisms that link environmental change to population productivity. This information can help to ensure that fisheries management serves to increase resilience of salmon populations and avoids actions that amplify potential negative consequences of climate change. This dissertation seeks to contribute to the informed management of Pacific salmon in a warming world through development of theory and in-depth exploration of cases where salmon populations have responded to changing environments. Chapter 1 considers the underappreciated phenomenon of temporal selection in fisheries and its implications for climate adaptation by salmon and other fishes. Chapter 2 tests a series of hypotheses that link observed warming in Lake Iliamna, Alaska to changes in sockeye salmon life-history and productivity. Chapter 3 describes a novel pattern of adult mortality in spawning sockeye salmon and demonstrates that low streamflow can create habitat conditions under which density-dependent spawning failure may occur. Chapter 4 describes changes in reproductive timing of Cedar River, Washington sockeye salmon and examines the relative influence of natural and artificial selection on phenological change and climate change resilience. Collectively, this research demonstrates some of the diverse responses that can be expected in salmon populations responding to climate change, emphasizes the importance of life-history and phenological diversity as adaptive pathways for populations impacted by climate change, and argues for management that maximizes these forms of diversity.

This book was released on 2017-11-13 with total page 1075 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first comprehensive review of the current and future effects of climate change on the world’s fisheries and aquaculture operations The first book of its kind, Climate Change Impacts on Fisheries and Aquaculture explores the impacts of climate change on global fisheries resources and on marine aquaculture. It also offers expert suggestions on possible adaptations to reduce those impacts. The world's climate is changing more rapidly than scientists had envisioned just a few years ago, and the potential impact of climate change on world food production is quite alarming. Nowhere is the sense of alarm more keenly felt than among those who study the warming of the world's oceans. Evidence of the dire effects of climate change on fisheries and fish farming has now mounted to such an extent that the need for a book such as this has become urgent. A landmark publication devoted exclusively to how climate change is affecting and is likely to affect commercially vital fisheries and aquaculture operations globally, Climate Change Impacts on Fisheries and Aquaculture provides scientists and fishery managers with a summary of and reference point for information on the subject which has been gathered thus far. Covers an array of critical topics and assesses reviews of climate change impacts on fisheries and aquaculture from many countries, including Japan, Mexico, South Africa, Australia, Chile, US, UK, New Zealand, Pacific Islands, India and others Features chapters on the effects of climate change on pelagic species, cod, lobsters, plankton, macroalgae, seagrasses and coral reefs Reviews the spread of diseases, economic and social impacts, marine aquaculture and adaptation in aquaculture under climate change Includes special reports on the Antarctic Ocean, the Caribbean Sea, the Arctic Ocean and the Mediterranean Sea Extensive references throughout the book make this volume both a comprehensive text for general study and a reference/guide to further research for fisheries scientists, fisheries managers, aquaculture personnel, climate change specialists, aquatic invertebrate and vertebrate biologists, physiologists, marine biologists, economists, environmentalist biologists and planners.

Available in PDF, EPUB and Kindle. Book excerpt: The stresses associated with climate change are expected to be felt keenly as human population grows to a projected 9 billion by the middle of this century, increasing the demand for resources and supporting infrastructure. Therefore, information to assess vulnerabilities to climate change is needed to support policies and investments designed to increase resilience in human and Earth systems. There are currently many observing systems that capture elements of how climate is changing, for example, direct measurements of atmospheric and ocean temperature. Although those measurements are essential for understanding the scale and nature of climate change, they do not necessarily provide information about the impacts of climate change on humans that are especially relevant for political and economic planning and decision making. Monitoring Climate Change Impacts tackles the challenge of developing an illustrative suite of indicators, measurements (and the locations around the globe where the measurements can be applied), and metrics that are important for understanding global climate change and providing insight into environmental sustainability. Eight panels provided input on: cryosphere, land-surface and terrestrial ecosystems, hydrology and water resources, atmosphere, human health and other dimensions, oceans (both physical and biological/chemical), and natural disasters. The book also provides an illustrative set of metrics that are likely to be affected by climate change over the next 20-25 years and, when taken together, can potentially give advance warning of climate-related changes to the human and environment systems.

This book was released on 2017 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation examines specific commercial fisheries in different geographic locations. The over-arching theme is to examine natural and/or anthropogenic perturbations in species dynamics. This dissertation also extends the association of species dynamics in perturbed systems to fisher based economies and human-health. Given the spatial and temporal nature of biological systems, spatial models and spatial-temporal models are applied to understand system dynamics with environmental stochasticity as a key determinant. An integrated nested laplace approximation spatial-temporal model explains fisheries abundance, (2) spatial bionomic models identify optimal management strategies in a changing fishery, (3) conditional auto-regressive models explain spatial differences in fisher well-being. This thesis will test whether distribution of the summer flounder can be explained by regional climate driven increase in ocean temperature in the Mid-Altantic Bight, USA; develops three models calibrated to the Maine, USA green sea urchin fishery since 1995, that is used to test whether periodic closures are optimal to permit stock regeneration, or whether the creation of a marine reserve is optimal; provide empirical evidence to demonstrate a relationship between malnutrition in artisanal fisher communities an degradation in coral reef ecosystems in Indonesia. The results suggest that all management decisions take into consideration a precautionary approach that account for stochastic environmental events. Local sources of anthropogenic stressors should be mitigated, given that regional policies have a higher chance of ameliorating and off-setting global climate change stressors.

Available in PDF, EPUB and Kindle. Book excerpt: Shifting Baselines explores the real-world implications of a groundbreaking idea: we must understand the oceans of the past to protect the oceans of the future. In 1995, acclaimed marine biologist Daniel Pauly coined the term "shifting baselines" to describe a phenomenon of lowered expectations, in which each generation regards a progressively poorer natural world as normal. This seminal volume expands on Pauly's work, showing how skewed visions of the past have led to disastrous marine policies and why historical perspective is critical to revitalize fisheries and ecosystems. Edited by marine ecologists Jeremy Jackson and Enric Sala, and historian Karen Alexander, the book brings together knowledge from disparate disciplines to paint a more realistic picture of past fisheries. The authors use case studies on the cod fishery and the connection between sardine and anchovy populations, among others, to explain various methods for studying historic trends and the intricate relationships between species. Subsequent chapters offer recommendations about both specific research methods and effective management. This practical information is framed by inspiring essays by Carl Safina and Randy Olson on a personal experience of shifting baselines and the importance of human stories in describing this phenomenon to a broad public. While each contributor brings a different expertise to bear, all agree on the importance of historical perspective for effective fisheries management. Readers, from students to professionals, will benefit enormously from this informed hindsight.

Available in PDF, EPUB and Kindle. Book excerpt: Overfishing. For the world’s oceans, it’s long been a worrisome problem with few answers. Many of the global fish stocks are at a dangerous tipping point, some spiraling toward extinction. But as older fishing fleets retire and new technologies develop, a better, more sustainable way to farm this popular protein has emerged to profoundly shift the balance. The Blue Revolution tells the story of the recent transformation of commercial fishing: an encouraging change from maximizing volume through unrestrained wild hunting to maximizing value through controlled harvesting and farming. Entrepreneurs applying newer, smarter technologies are modernizing fisheries in unprecedented ways. In many parts of the world, the seafood on our plates is increasingly the product of smart decisions about ecosystems, waste, efficiency, transparency, and quality. Nicholas P. Sullivan presents this new way of thinking about fish, food, and oceans by profiling the people and policies transforming an aging industry into one that is “post-industrial”—fueled by “sea-foodies” and locavores interested in sustainable, traceable, quality seafood. Catch quotas can work when local fishers feel they have a stake in the outcome; shellfish farming requires zero inputs and restores nearshore ecosystems; new markets are developing for kelp products, as well as unloved and “underutilized” fish species. Sullivan shows how the practices of thirty years ago that perpetuated an overfishing crisis are rapidly changing. In the book’s final chapters, Sullivan discusses the global challenges to preserving healthy oceans, including conservation mechanisms, the impact of climate change, and unregulated and criminal fishing in international waters. In a fast-growing world where more people are eating more fish than ever before, The Blue Revolution brings encouraging news for conservationists and seafood lovers about the transformation of an industry historically averse to change, and it presents fresh inspiration for entrepreneurs and investors eager for new opportunities in a blue-green economy.

Available in PDF, EPUB and Kindle. Book excerpt: Climate Change and Ocean Governance brings together authors from political science and cognate disciplines to examine the political and policy dimensions of climate change for our oceans. The environmental, social and economic consequences of oceanic change present tremendous challenges for governments and other actors. New and innovative policies for governing oceans and seas - and for managing vital marine resources - have never been more important. Existing national and international institutions for marine governance that were created when oceanic conditions were relatively static may not be adequate for a future characterized by continuous oceanic change. Responses to oceanic change will result in winners and losers, and thus will involve politics in all its manifestations. This book reveals the unavoidable connections between climate change, the oceans, and questions of governance. It provides valuable lessons for researchers, policymakers and activists concerned about governing oceanic change into the future.

Available in PDF, EPUB and Kindle. Book excerpt: "This book is a narrative non-fiction, based on the patchy epistemologies of traditional small-scale fishers in India and the Indian Ocean Region. It specifically explores the impact of climate change on Fish and Fishers, and the mutual entanglements in their eco-social world. Further, it critically examines the nature of climate change adaptation and its implications on small-scale fisheries. Both climate change impact and adaptation responses are examined from the situated knowledge and everyday lived experiences of Fishers. Stories of their everyday struggles from diverse eco-social worlds shape these patchy epistemologies. Further, this book through these stories unearths the transitions in governance and changing relationships between Fish, Fishers, and the rest of the eco-social world. Responding ethically to the problems of climate change, warming oceans, fish scarcity, overfishing, and pollution requires us to break away from the paradigms that locate Nature and Society as binaries and commodities. Blue justice can be achieved only if strategies aimed at adaptation, conservation and well-being are dialogical, inclusive, and Fish-Fisher centred. This book offers insights into the worldviews of Fishers, their stewardship, wisdom, and experience in healing today's warming world. Locating the eco-social worlds of Fish and Fishers in alternative worldviews, this book strives to find meaningful pathways for just transitions. It will be of interest to academics and researchers working in the field of climate change, fisheries, disaster studies, and sustainable livelihoods as well as related subjects of social work and social justice"--
