Available in PDF, EPUB and Kindle. Book excerpt: Recently, a number of papers have addressed global warming and freshwater fisheries. The recent report to Congress by the US Environmental Protection Agency included an analysis of potential effects of global warming on fisheries of the Great Lakes, California, and the Southeast. In California, the report stated that salinity increases in the San Francisco Bay could enhance the abundance of marine fish species, while anadromous species could be adversely affected. This paper discusses global climate changes and the effects on Pacific Northwest Salmonids. The impacts of climate change or Spring Chinook production in the Yakima Sub-basin was simulated using a computer modeling system developed for the Northwest Power planning council. 35 refs., 1 fig., 1 tab.

This book was released on 2013-11-20 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild salmon, trout, char, grayling, and whitefish (collectively salmonids) have been a significant local food and cultural resource for Pacific Northwest peoples for millennia. The location, size, and distribution of urban areas along streams, rivers, estuaries, and coasts directly and indirectly alter and degrade wild salmonid populations and their habitats. Although urban and exurban areas typically cover a smaller fraction of the landscape than other land uses combined, they have profound consequences for local ecosystems, aquatic and terrestrial populations, and water quality and quantity.

Available in PDF, EPUB and Kindle. Book excerpt: The symposium "Pacific Salmon and Their Ecosystems: Status and Future Options',' and this book resulted from initial efforts in 1992 by Robert J. Naiman and Deanna J. Stouder to examine the problem of declining Pacific salmon (Oncorhynchus spp.). Our primary goal was to determine informational gaps. As we explored different scientific sources, state, provincial, and federal agencies, as well as non-profit and fishing organizations, we found that the information existed but was not being communicated across institutional and organizational boundaries. At this juncture, we decided to create a steering committee and plan a symposium to bring together researchers, managers, and resource users. The steering committee consisted of members from state and federal agencies, non-profit organizations, and private industry (see Acknowledgments for names and affiliations). In February 1993, we met at the University of Washington in Seattle to begin planning the symposium. The steering committee spent the next four months developing the conceptual framework for the symposium and the subsequent book. Our objectives were to accomplish the following: (1) assess changes in anadromous Pacific Northwest salmonid populations, (2) examine factors responsible for those changes, and (3) identify options available to society to restore Pacific salmon in the Northwest. The symposium on Pacific Salmon was held in Seattle, Washington, January 10-12, 1994. Four hundred and thirty-five people listened to oral presentations and examined more than forty posters over two and a half days. We made a deliberate attempt to draw in speakers and attendees from outside the Pacific Northwest.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwestâ€"economic, recreational, symbolicâ€"is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runsâ€"and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problemâ€"starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including: Salmon biology and geographyâ€"their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activitiesâ€"grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issueâ€"policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.

Book excerpt: This work resulted from a continuing multidisciplinary analysis of species preservation and global change. The paper explores the economic cost of a potential regional warming as it affects one Pacific Northwest natural resource, the spring chinook salmon (Oncorhynchus tshcawytscha). Climate change and planned habitat improvements impact the production and economic value of soling chinook salmon of the Yakima River tributary of the Columbia River in eastern Washington. The paper presents a derivation of the total economic value of a chinook salmon, which includes the summation of the existence, commercial, recreational, and capital values of the fish. When currently available commercial, recreational, existence, and capital values for chinook salmon were applied to estimated population changes, the estimated change in the economic value per fish associated with reduction of one fish run proved significant.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The Far North, a land of extreme weather and intense beauty, is the only region of North America whose ecosystems have remained reasonably intact. Humans are newcomers there and nature predominates. As is widely known, recent changes in the Earth's atmosphere have the potential to create rapid climatic shifts in our life-time and well into the future. These changes, a product of southern industrial society, will have the greatest impact on ecosystems at northern latitudes, which until now have remained largely undisturbed. In this fragile balance, as terrestrial and aquatic habitats change, animal and human populations will be irrevocably altered.
