Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwestâ€"economic, recreational, symbolicâ€"is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runsâ€"and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problemâ€"starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including: Salmon biology and geographyâ€"their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activitiesâ€"grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issueâ€"policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.

Download or read book Fisheries Ecology and Management written by Carl J. Walters and published by Princeton University Press. This book was released on 2020-06-30 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses, and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management, this useful guide will also be widely read by ecologists and fisheries scientists.

Download or read book Encyclopedia of Water Politics and Policy in the United States written by Steven L. Danver and published by CQ Press. This book was released on 2011-05-17 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water has had an immeasurable impact on the history and growth of the United States. As an essential element of life water has been and remains a constant source of conflict and controversy as different constituencies fight for limited resources. The Encyclopedia of Water Politics and Policy in the United States is the most comprehensive reference source available that analyzes water-related issues in America. A diverse group of over 100 scholars have provided their research and analysis of why water is so significant by tracing its impact on issues like national and state boundaries, western migration, urbanization, and the economy. This volume chronicles the origins of present-day water problems, political conflicts, the impact of legislation and court decisions on the use of water resources, the major projects undertaken across the country, and what experts are proposing be done to preserve this basic component of the environment. Going back some 150 years, the Encyclopedia provides an overview of approximately 280 pieces of water-related legislation, legal cases, people, projects, and organizations that have shaped the history of the United States. In addition to historical coverage, the volume also addresses many current environmental issues including acid rain, agriculture, climate change, mining, erosion, levees and dams, pollution, urbanization, and wastewater treatment. The volume’s A to Z entries are divided into four sections: Regional Water Politics and Policy: Essays providing a narrative background and overview Major Issues in Water Politics and Policy: A comprehensive list of issues from colonial times to the present Law and Government: The people and legislation that have shaped water policy in the United States Places and Projects: Extensive coverage of the projects (including dams and aqueducts) the government has undertaken to develop the nation’s waterways Throughout the volume, concise text features highlight important events, advocacy groups, people, books, and sites important to water politics and policy. A thematic table of contents allows users to easily locate reclamation projects geographically, biographies of important figures, current issues by subject area, government agencies, and legal cases.

Download or read book Sex Control in Aquaculture written by Hanping Wang and published by John Wiley & Sons. This book was released on 2018-11-08 with total page 1969 pages. Available in PDF, EPUB and Kindle. Book excerpt: Awarded Bookauthority's "Best Aquaculture Books of all Time" A comprehensive resource that covers all the aspects of sex control in aquaculture written by internationally-acclaimed scientists Comprehensive in scope, Sex Control in Aquaculture first explains the concepts and rationale for sex control in aquaculture, which serves different purposes. The most important are: to produce monosex stocks to rear only the fastest-growing sex in some species, to prevent precocious or uncontrolled reproduction in other species and to aid in broodstock management. The application of sex ratio manipulation for population control and invasive species management is also included. Next, this book provides detailed and updated information on the underlying genetic, epigenetic, endocrine and environmental mechanisms responsible for the establishment of the sexes, and explains chromosome set manipulation techniques, hybridization and the latest gene knockout approaches. Furthermore, the book offers detailed protocols and key summarizing information on how sex control is practiced worldwide in 35 major aquaculture species or groups, including fish and crustaceans, and puts the focus on its application in the aquaculture industry. With contributions from an international panel of leading scientists, Sex Control in Aquaculture will appeal to a large audience: aquaculture/fisheries professionals and students, scientists or biologists working with basic aspects of fish/shrimp biology, growth and reproductive endocrinology, genetics, molecular biology, evolutionary biology, and R&D managers and administrators. This text explores sex control technologies and monosex production of commercially-farmed fish and crustacean species that are highly in demand for aquaculture, to improve feed utilization efficiency, reduce energy consumption for reproduction and eliminate a series of problems caused by mixed sex rearing. Thus, this book: Contains contributions from an international panel of leading scientists and professionals in the field Provides comprehensive coverage of both established and new technologies to control sex ratios that are becoming more necessary to increase productivity in aquaculture Includes detailed coverage of the most effective sex control techniques used in the world's most important commercially-farmed species Sex Control in Aquaculture is the comprehensive resource for understanding the biological rationale, scientific principles and real-world practices in this exciting and expanding field.

Book excerpt: Praise for the Previous Edition (0 415 92612 2): ...lively and provocative...this book will teach you something startling on nearly every page... --The New York Times Book Review Like the Emerald City, Las Vegas glitters brightly in the vast Nevada desert, a haven for refugees from ordinary America. A hip, iconic, playground that exports nothing, it nonetheless earns billions from consumer services alone -- gambling, hotels, gaming, and entertainment. It is, historian Hal Rothman argues, the quintessential city of the future. As other cities try to mirror its success and huge, respectable corporations like Coca-Cola invest in a piece of the pie, the very traits that have ostracized Las Vegas in the past -- hedonism, money worship, and permissiveness -- have today made it America's fastest growing urban center. From the gambling-driven, mob-run Sin City of the 1940s to the corporatization of the Strip as a respectable family entertainment center after the 1970s, Las Vegas has shown incredible economic resilience and adaptability. The first full account of America's new dream capital, Neon Metropolis brilliantly shows how Las Vegas gambled on the post-industrial service economy well before the rest of the country knew it was coming, and won.

Download or read book Devil s Bargains written by Hal Rothman and published by . This book was released on 1998 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: The West is popularly perceived as America's last outpost of unfettered opportunity, but twentieth-century corporate tourism has transformed it into America's "land of opportunism." From Sun Valley to Santa Fe, towns throughout the West have been turned over to outsiders—and not just to those who visit and move on, but to those who stay and control. Although tourism has been a blessing for many, bringing economic and cultural prosperity to communities without obvious means of support or allowing towns on the brink of extinction to renew themselves; the costs on more intangible levels may be said to outweigh the benefits and be a devil's bargain in the making. Hal Rothman examines the effect of twentieth-century tourism on the West and exposes that industry's darker side. He tells how tourism evolved from Grand Canyon rail trips to Sun Valley ski weekends and Disneyland vacations, and how the post-World War II boom in air travel and luxury hotels capitalized on a surge in discretionary income for many Americans, combined with newfound leisure time. From major destinations like Las Vegas to revitalized towns like Aspen and Moab, Rothman reveals how the introduction of tourism into a community may seem innocuous, but residents gradually realize, as they seek to preserve the authenticity of their communities, that decision-making power has subtly shifted from the community itself to the newly arrived corporate financiers. And because tourism often results in a redistribution of wealth and power to "outsiders," observes Rothman, it represents a new form of colonialism for the region. By depicting the nature of tourism in the American West through true stories of places and individuals that have felt its grasp, Rothman doesn't just document the effects of tourism but provides us with an enlightened explanation of the shape these changes take. Deftly balancing historical perspective with an eye for what's happening in the region right now, his book sets new standards for the study of tourism and is one that no citizen of the West whose life is touched by that industry can afford to ignore.
