This book was released on 2012-02-02 with total page 681 pages. 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.

Book excerpt: Pacific salmon are an important biological and economic resource of countries of the North Pacific rim. They are also a unique group of fish possessing unusually complex life histories. There are seven species of Pacific salmon, five occurring on both the North American and Asian continents (sockeye, pink, chum, chinook, and coho) and two (masu and amago) only in Asia. The life cycle of the Pacific salmon begins in the autumn when the adult female deposits eggs that are fertilized in gravel beds in rivers or lakes. The young emerge from the gravel the following spring and will either migrate immediately to salt water or spend one or more years in a river or lake before migrating. Migrations in the ocean are extensive during the feeding and growing phase, covering thousands of kilometres. After one or more years the maturing adults find their way back to their home river, returning to their ancestral breeding grounds to spawn. They die after spawning and the eggs in the gravel signify a new cycle. Upon this theme Pacific salmon have developed many variations, both between as well as within species. Pacific Salmon Life Histories provides detailed descriptions of the different life phases through which each of the seven species passes. Each chapter is written by a scientist who has spent years studying and observing a particular species of salmon. Some of the topics covered are geographic distribution, transplants, freshwater life, ocean life, development, growth, feeding, diet, migration, and spawning behaviour. The text is richly supplemented by numerous maps, illustrations, colour plates, and tables and there is a detailed general index, as well as a useful geographical index.

Available in PDF, EPUB and Kindle. Book excerpt: Canada's Wild Salmon Policy (WSP) was released in June 2005 with a goal to restore and maintain healthy and diverse salmon populations and their habitats. Strategy 3, Action Step 3.1 aims to include ecosystem values in decision-making by proposing "ecosystem indicators" to monitor the status of freshwater and terrestrial ecosystems. The scientific basis for proposing ecosystem indicators within the WSP recognizes that Pacific salmon play an important role in marine, freshwater, and terrestrial ecosystems, including streams, lakes, riparian forest and wildlife food webs. Managers influence these ecosystems by considering changes in fisheries regulations (i.e., harvest levels) and artifical enhancement (e.g., hatcheries). This work serves three functions: (1) provide a first attempt at developing ecosystem indicators for Strategy 3 of the Wild Salmon Policy; (2) recommend further development and refinement of ecosystem indicators; and (3) suggest next steps.

This book was released on 1996-07-31 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwest--economic, recreational, symbolic--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 runs--and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problem--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 geography--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 activities--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 issue--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.

Download or read book Physiological Ecology of Pacific Salmon written by Cornelis Groot and published by UBC Press. This book was released on 2010-10-01 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.

Managers influence these ecosystems by considering changes in fisheries regulations (i.e., harvest levels) and artificial enhancement (e.g., hatcheries). Thus, the role of ecosystem indicators is to provide a measure of ecosystem responses to changes in spawner abundance, thereby helping managers understand how changes in their actions affect freshwater and terrestrial ecosystems. This work serves three functions: (1) provide a first attempt at developing ecosystem indicators for Strategy 3 of the Wild Salmon Policy; (2) recommend further development and refinement of ecosystem indicators; and (3) suggest next steps. To serve these functions, we reviewed the literature to develop a better understanding of the linkages among the five Pacific salmon species and freshwater / terrestrial ecosystems, and used our resulting summary on the "state of the science" to provide a scientific rationale for recommending ecosystem indicators and next steps.

Book excerpt: 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.
