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.

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.

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.

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.

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 forests and wildlife food webs. 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.
