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.

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.

Download or read book Fish Law and Colonialism written by Douglas Colebrook Harris and published by University of Toronto Press. This book was released on 2001-01-01 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: An engrossing history, Fish, Law, and Colonialism recounts the human conflict over fish and fishing in British Columbia and of how that conflict was shaped by law. Pacific salmon fisheries, owned and managed by Aboriginal peoples, were transformed in the late nineteenth and early twentieth centuries by commercial and sport fisheries backed by the Canadian state and its law. Through detailed case studies of the conflicts over fish weirs on the Cowichan and Babine rivers, Douglas Harris describes the evolving legal apparatus that dispossessed Aboriginal peoples of their fisheries. Building upon themes developed in literatures on state law and local custom, and law and colonialism, he examines the contested nature of the colonial encounter on the scale of a river. In doing so, Harris reveals the many divisions both within and between government departments, local settler societies, and Aboriginal communities. Drawing on government records, statute books, case reports, newspapers, missionary papers and a secondary anthropological literature to explore the roots of the continuing conflict over the salmon fishery, Harris has produced a superb, and timely, legal and historical study of law as contested terrain in the legal capture of Aboriginal salmon fisheries in British Columbia.

This book was released on 2013-03-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

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.

Download or read book King of Fish written by David Montgomery and published by Basic Books. This book was released on 2009-04-28 with total page 306 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: PNBA BESTSELLER • “A powerful and inspiring story. Guido Rahr’s mission to save the wild Pacific salmon leads him into adventures that make for a breathtakingly exciting read.”—Ian Frazier, author of Travels in Siberia Editors’ Choice: The New York Times Book Review • Outside Magazine • National Book Review • Forbes In the tradition of Mountains Beyond Mountains and The Orchid Thief, Stronghold is Tucker Malarkey’s eye-opening account of one of the world’s greatest fly fishermen and his crusade to protect the world’s last bastion of wild salmon. From a young age, Guido Rahr was a misfit among his family and classmates, preferring to spend his time in the natural world. When the salmon runs of the Pacific Northwest began to decline, Guido was one of the few who understood why. As dams, industry, and climate change degraded the homes of these magnificent fish, Rahr saw that the salmon of the Pacific Rim were destined to go the way of their Atlantic brethren: near extinction. An improbable and inspiring story, Stronghold takes us on a wild adventure, from Oregon to Alaska to one of the world’s last remaining salmon strongholds in the Russian Far East, a landscape of ecological richness and diversity that is rapidly being developed for oil, gas, minerals, and timber. Along the way, Rahr contends with scientists, conservationists, Russian oligarchs, corrupt officials, and unexpected allies in an attempt to secure a stronghold for the endangered salmon, an extraordinary keystone species whose demise would reverberate across the planet. Tucker Malarkey, who joins Rahr in the Russian wilderness, has written a clarion call for a sustainable future, a remarkable work of natural history, and a riveting account of a species whose future is closely linked to our own. Praise for Stronghold “This book isn’t just about fish, it’s about life itself and the fragile unseen threads that connect all creatures across this beleaguered orb we call home. Guido Rahr’s quest to save the world’s wild salmon should serve as an inspiration—and a provocation—for us all, and Tucker Malarkey’s exquisite book captures Rahr’s weird and wonderful story with poignancy, humor, and grace.”—Hampton Sides, author of In the Kingdom of Ice and Blood and Thunder “A crazy-good, intensely lived book that reads like an international thriller—only it’s our beloved salmon playing the part of diamonds or oil or gold.”—David James Duncan, author of The River Why and The Brothers K
