Book excerpt: In spite of considerable efforts to restore natural runs of anadromous salmonids in the Pacific Northwest, they remain at risk of extirpation. Along with many other factors influencing the decline, stocking from hatcheries over the past hundred years is often suggested to be a major cause. The listing of over two dozen runs of salmon under the Endangered Species Act has catalyzed a re-assessment of hatchery effects on naturally spawning salmon. Recent policies have placed a much greater emphasis on restoring runs of wild salmon rather than maintaining runs through stocking from hatchery production. Except at the most superficial level, there is no consensus about how to define "wild." Rather, there is a continuum of definitions for "wild" and each definition supports an implicit policy goal. The precise way in which "wild salmon" is defined potentially has profound policy implications. Ultimately, the choice of definition is a policy decision that incorporates science as one of several factors influencing the decision. A suite of options, often poorly articulated, for defining "wild" are available to policy makers who are selecting recovery goals. To test a subset of the available definitions of wild, I quantified the number of hatchery and naturally spawning salmon for 19 populations of Oregon coastal coho. "Wild" was defined by types 1 through 5 based on the number of hatchery fish released annually and the number of naturally spawning hatchery adults. As currently managed by the Oregon Department of Fish and Wildlife, the Oregon coast has a range of "types" of coho salmon. By clearly and explicitly defining "wild" as steps along a continuum, policy makers and managers can more effectively monitor and achieve specific salmon recovery goals.

Book excerpt: "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.

Book excerpt: The salmon that symbolize the Pacific Northwest's natural splendor are now threatened with extinction across much of their ancestral range. In studying the natural and human forces that shape the rivers and mountains of that region, geologist David Montgomery has learned to see the evolution and near-extinction of the salmon as a story of changing landscapes. Montgomery shows how a succession of historical experiences -first in the United Kingdom, then in New England, and now in the Pacific Northwest -repeat a disheartening story in which overfishing and sweeping changes to rivers and seas render the world inhospitable to salmon. In King of Fish , Montgomery traces the human impacts on salmon over the last thousand years and examines the implications both for salmon recovery efforts and for the more general problem of human impacts on the natural world. What does it say for the long-term prospects of the world's many endangered species if one of the most prosperous regions of the richest country on earth cannot accommodate its icon species? All too aware of the possible bleak outcome for the salmon, King of Fish concludes with provocative recommendations for reinventing the ways in which we make environmental decisions about land, water, and fish.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
