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.

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

Download or read book Totem Salmon written by Freeman House and published by Beacon Press. This book was released on 2000-05-12 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.

Download or read book Salmon written by Nicolaas Mink and published by Reaktion Books. This book was released on 2013-09-15 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rich in omega-3 fatty acids, cheap, and widely available, salmon is often listed as an essential part of any diet. A delicious and versatile fish, it can be used to make sashimi, cold smoked for lox, or shaped into a fishcake as an alternative to hamburgers. But while salmon is enjoyed all over the globe, it also swims at the center of controversy, with commercial fishing, global warming, and loss of freshwater habitats all threatening salmon populations and the ecological and health impacts of intense salmon farming under fire. In this beautifully illustrated book, Nicolaas Mink takes readers on a culinary journey from the coast of Alaska to the rivers of Scotland, tracing salmon’s history from the earliest known records to the present. He tells the story of how the salmon was transformed from an abundant fish found seasonally along coastal regions to a mass-produced canned food and a highly prized culinary delight. Exploring the nutritional benefits of this fish, he examines recent studies that show how these benefits diminish in farm-raised salmon. With many delicious recipes, Salmon is the perfect gift for every fish lover.
