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 Pacific Salmon Life Histories written by Cornelis Groot and published by UBC Press. This book was released on 1991 with total page 602 pages. Available in PDF, EPUB and Kindle. 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: From one of Canada's greatest journalists comes the epic story of British Columbia's Fraser River. As the dust jacket for the originally edition-published half a century ago-declared:"Shaped like a giant fishhook stuck into the Pacific Ocean, the mighty Fraser is one of the most important rivers of North America, politically, economically, and historically. Compelling the reader's interest with the power and vigour of his narrative, Bruce Hutchison explores the Fraser's romantichistory as one of Canada's two main channels of civilization. The Fraser's story is that of British Columbia and its people, and Mr. Hutchison shows that it provides some of the richest yet least known chapters in Canadian history. These he unrolls in an unforgettable panorama, from the days ofSpanish discovery to the story of the city of Vancouver, the river's most remarkable product. In its gold, its steamboating, its fur; as a fisherman's paradise, and as the largest untapped source of electrical power in North America-the story of the Fraser is one of colour and high drama. It isexciting reading."The Wynford Edition includes a new introduction by Vaughn Palmer, one of Canada's foremost political journalists and a winner of the Bruce Hutchison Award. Palmer's introduction puts both the book and Hutchison's career in historical context for modern readers.
Download or read book Climate Change Implications for Fisheries and Aquaculture written by K. L. Cochrane and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the current scientific knowledge available on climate change implications for fisheries and aquaculture is provided through three technical papers that were presented and discussed during the Expert Workshop on Climate Change Implications for Fisheries and Aquaculture (Rome, 7-9 April 2008). A summary of the workshop outcomes as well as key messages on impacts of climate change on aquatic ecosystems and on fisheries- and aquaculture-based livelihoods are provided in the introduction of this Technical Paper. The first paper reviews the physical and ecological impacts of climate change relevant to marine and inland capture fisheries and aquaculture. The paper begins with a review of the physical impacts of climate change on marine and freshwater systems and then connects these changes with observed effects on fish production processes. It also outlines a series of scenarios of climate change impacts on fish production and ecosystems through case studies in different regions and ecosystems. The second paper tackles the consequences of climate change impacts on fisheries and their dependent communities. It analyses the exposure, sensitivity and vulnerability of fisheries to climate change and presents examples of adaptive mechanisms currently used in the sector. The contribution of fisheries to greenhouse gas emissions is addressed and examples of mitigation strategies are given. The role of public policy and institutions in promoting climate change adaptation and mitigation is also explored. Finally, the third paper addresses the impacts of climate change on aquaculture. It provides an overview of the current food fish and aquaculture production and a synthesis of existing studies on climate change effects on aquaculture and fisheries. The paper focuses on the direct and indirect impacts of climate change on aquaculture, in terms of biodiversity, fish disease and fishmeal. Contribution of aquaculture to climate change is addressed (carbon emission and carbon sequestration), as well as possible adaptation and mitigation measures that could be implemented.

Download or read book The Atlantic Salmon in the History of North America written by R. W. Dunfield and published by Fisheries and Oceans, Scientific Information and Publications Branch. This book was released on 1985 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic salmon (Salmo salar) has occupied a salient position in the history of eastern North America for at least the past 1000 years. Initially the species occupied a prominant niche in the prolific web of life that existed throughout its former occurrence area; millions of pounds of salmon were produced annually from the freshwater streams between New York and Ungava - a resource that was a principal food source for the Amerindian cultures which shared its range. In a chronological and cumulative way, the salmon became an increasingly important factor in both the domestic and commercial life of the developing colonies; it provided a recreational outlet for the sportsman, and evolved as a principal object of intellectual and scientific investigation. The documented specifics of the salmon's history, however, are largely comprised of repetitive instances of overexploitation, careless destruction of stocks and their environment, and ineffectual conservation actions. Despite the species' former importance, its more recent history is one of declining presence, and its destiny appears to be extinction. By documenting this story of discovery, exploitation, and decline, the urgent need for the employment of sound resource management practices to preserve the salmon is emphasized.

Download or read book Fraser River Sockeye 1994 written by Fraser River Sockeye Public Review Board (Canada) and published by . This book was released on 1995 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fraser River Sockeye Public Review Board conducted an independent investigation of the apparent disappearance of several million sockeye salmon which would normally have migrated to spawning areas in the Fraser River watershed in 1994. The Board review had three main objectives: to identify the reasons for the discrepancies in the expected and actual number of sockeye salmon arriving on the spawning ground; to evaluate the accuracy of the Pacific Salmon Commission's methodology for estimating run sizes and sockeye escapement in the Fraser River; and to make recommendations on how any deficiencies can be corrected. This report presents the findings and recommendations of the Board and includes an examination of the role of environmental factors, a review of the institutions involved and the fishery management techniques employed, and an evaluation of the federal Aboriginal Fisheries Strategy.
