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.

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.

This book was released on 2012-02-02 with total page 681 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Using Integrated Population Models to Evaluate Fishery and Environmental Impacts on Pacific Salmon Viability written by Eric R. Buhle and published by . This book was released on 2018 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Age- or stage-structured population models, also known as life cycle models, are a mainstay of applied ecology and conservation, particularly in fisheries management. The data available to inform parameters in such models are, however, often limited and variable in quality. Ad-hoc, piecemeal approaches to parameter estimation can lead to biased inference about key processes, such as the strength of density dependence and the magnitude of environmental variability in recruitment. Recent statistical advances have facilitated a more rigorous, comprehensive approach to fitting life cycle models by combining all relevant data into a joint likelihood function. Such integrated population models (IPMs) have been widely applied in marine fisheries stock assessment, but are less familiar in salmonid management. We developed a multipopulation IPM for Pacific salmon (Oncorhynchus spp.) that accounts for spatial and temporal variability in adult recruitment and age structure, the presence of hatchery-origin spawners, and observation error in abundance, age-composition, and hatchery-fraction data. The method is analogous to traditional spawner–recruit modeling based on brood-table reconstruction, but the model is fitted to the “raw” data and distinguishes between process and observation error. We applied the model to 29 populations of spring/summer Chinook salmon in the Snake River and Upper Columbia River Evolutionarily Significant Units (ESUs), and used the estimated parameters and states to simulate the impact of fishery exploitation rate on future abundance and quasi-extinction risk. As expected, predicted abundance declined and quasi-extinction risk increased across a range of fixed harvest rates from 0–0.3. The slope of the decline in abundance, relative to population-specific carrying capacity, was inversely related to intrinsic productivity. Large-scale environmental fluctuations (e.g., ocean conditions and hydrosystem operations, represented by the shared process error) were at least as important as harvest in determining long-term population viability. If future environmental conditions are relatively poor, and especially if they are assumed to have undergone a persistent state shift at some point in the last 60 years, then quasi-extinction risks are dramatically elevated even in the absence of harvest. We see potential for the further development of IPMs (e.g., the inclusion of more detailed stage structure) and their application to salmon conservation problems throughout the Pacific Northwest.

Download or read book Ecology of Salmonids in Estuaries around the World written by Colin D. Levings and published by UBC Press. This book was released on 2016-05-15 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: For centuries, biologists have marvelled at how anadromous salmonids – fish that pass from rivers into oceans and back again – survive as they migrate between these two very different environments. Yet, relatively little is understood about what happens to salmonid species (including salmon, steelhead, char, and trout) in the estuaries where they make this transition from fresh to salt water. This book explains the critical role estuaries play in salmonid survival. Ecology of Salmonids in Estuaries around the World synthesizes information from a vast array of literature, to describe the specific adaptation of eighteen anadromous salmonids in four genera (Hucho, Oncorhynchus, Salmo, and Salvelinus) explain the ecological relationships between anadromous salmonids, the fish they coexist with, and their estuarine habitat discuss key fitness elements salmonids need for survival (including those relating to osmoregulation, growth and feeding mechanisms, and biotic interactions) provide guidance on how to conduct estuarine sampling and scientific aspects of management and recovery plans offer directions for future research. The critical reference is further enhanced by extensive supplementary appendices that are available online, including data tables, additional references on estuarine salmonids, and a primer on estuaries and salmonids for citizen scientists.

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.
