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.

"Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

Because of the pervasive and substantial decline of Atlantic salmon populations in Maine over the past 150 years, and because they are close to extinction, a comprehensive statewide action should be taken now to ensure their survival. The populations of Atlantic salmon have declined drastically, from an estimated half million adult salmon returning to U.S. rivers each year in the early 1800s to perhaps as few as 1,000 in 2001. The report recommends implementing a formalized decision-making approach to establish priorities, evaluate options and coordinate plans for conserving and restoring the salmon.

The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

As the new chief of the Michigan Department of Conservation’s Fish Division in 1964, Howard A. Tanner was challenged to “do something . . . spectacular.” He met that challenge by leading the successful introduction of coho salmon into the Michigan waters of the Great Lakes. This volume illustrates how Tanner was able to accomplish this feat: from a detailed account of his personal and professional background that provided a foundation for success; the historical and contemporary context in which the Fish Division undertook this bold step to reorient the state’s fishery from commercial to sport; the challenges, such as resistance from existing government institutions and finding funding, that he and his colleagues faced; the risks they took by introducing a nonnative species; the surprises they experienced in the first season’s catch; to, finally, the success they achieved in establishing a world-renowned, biologically and financially beneficial sport fishery in the Great Lakes. Tanner provides an engaging history of successfully introducing Pacific salmon into the lakes from the perspective of an ultimate insider.

Part lyrical natural history, part social and philosophical manifesto, Totem Salmon tells the story of a determined band of locals who've worked for over two decades to save one of the last purely native species of salmon in California. The book-call it the zen of salmon restoration-traces the evolution of the Mattole River Valley community in northern California as it learns to undo the results of rapacious logging practices; to invent ways to trap wild salmon for propagation; and to forge alliances between people who sometimes agree on only one thing-that there is nothing on earth like a Mattole king salmon. House writes from streamside: "I think I can hear through the cascades of sound a systematic plop, plop, plop, as if pieces of fruit are being dropped into the water. Sometimes this is the sound of a fish searching for the opening upstream; sometimes it is not. I breathe quietly and wait." Freeman House's writing about fish and fishing is erotic, deeply observed, and simply some of the best writing on the subject in recent literature. House tells the story of the annual fishing rituals of the indigenous peoples of the Klamath River in northern California, one that relies on little-known early ethnographic studies and on indigenous voices-a remarkable story of self-regulation that unites people and place. And his riffs on the colorful early history of American hatcheries, on property rights, and on the "happiness of the state" show precisely why he's considered a West Coast visionary. Petitions to list a dozen West Coast salmon runs under the provisions of the Endangered Species Act make saving salmon an issue poised to consume the Pacific West. "Never before, said Federal officials, has so much land or so many people been given notice that they will have to alter their lives to restore a wild species" (New York Times, 2/27/98). Totem Salmon is set to become the essential read for this newest chapter in our relations with other wild things.

Nautilus Award Silver Medal Winner, Ecology & Environment In search of a new story for our place on earth Being Salmon, Being Human examines Western culture’s tragic alienation from nature by focusing on the relationship between people and salmon—weaving together key narratives about the Norwegian salmon industry as well as wild salmon in indigenous cultures of the Pacific Northwest. Mueller uses this lens to articulate a comprehensive critique of human exceptionalism, directly challenging the four-hundred-year-old notion that other animals are nothing but complicated machines without rich inner lives and that Earth is a passive backdrop to human experience. Being fully human, he argues, means experiencing the intersection of our horizon of understanding with that of other animals. Salmon are the test case for this. Mueller experiments, in evocative narrative passages, with imagining the world as a salmon might see it, and considering how this enriches our understanding of humanity in the process. Being Salmon, Being Human is both a philosophical and a narrative work, rewarding readers with insightful interpretations of major philosophers—Descartes, Heidegger, Abram, and many more—and reflections on the human–Earth relationship. It stands alongside Abram’s Spell of the Sensuous and Becoming Animal, as well as Andreas Weber’s The Biology of Wonder and Matter and Desire—heralding a new “Copernican revolution” in the fields of biology, ecology, and philosophy.

Many of the processes influencing recruitment to an adult fish population or entry into a fishery occur very early in life. The variations in life histories and behaviours of young fish and the selective processes operating on this variation ultimately determine the identities and abundance of survivors. This important volume brings together contributions from many of the world's leading researchers from the field of fish ecology. The book focuses on three major themes of pressing importance in the analysis of the role that the early life history of fishes plays in the number and quality of recruits: the selective processes at play in their early life history; the contributions of early life history to the understanding of recruitment.
