Download or read book Salmonid Field Protocols Handbook written by David H. Johnson and published by . This book was released on 2007 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first publication to collect, standardize, and recommend a scientifically rigorous set of field protocols for monitoring and assessing salmon and trout populations. Includes five additional techniques that can be used with any of the 13 principle methods to supplement information gathered.Over four dozen fisheries experts throughout the U.S. Pacific Northwest and beyond contributed their time to pick, write, and review the most reliable protocols for enumerating salmonids in the field. Presented in an easy to use format, each of the 18 peer-reviewed protocols covers objectives, sample design, data handling, personnel and operational requirements, and field and office techniques, including survey forms.Standardized monitoring protocols will improve data reliability, maximize opportunities for data sharing and data set comparability, and ultimately improve the ability to assess status and trends. The Handbook will also support consistency in data collection for salmonids at the international level.

Download or read book The Atlantic Salmon written by Eric Verspoor and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.

Download or read book Salmon Without Rivers written by Jim Lichatowich and published by . This book was released on 1999-08 with total page 346 pages. Available in PDF, EPUB and Kindle. 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 A Long Trek Home written by Erin McKittrick and published by The Mountaineers Books. This book was released on 2009-10-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: CLICK HERE to download the first chapter from A Long Treak Home * Compelling adventure with an environmental focus * An informative natural and cultural history of one of our last wild coastlines * Author is a pioneer in "packrafting," an emerging trend in backcountry travel In June 2007, Erin McKittrick and her husband, Hig, embarked on a 4,000-mile expedition from Seattle to the Aleutian Islands, traveling solely by human power. This is the story of their unprecedented trek along the northwestern edge of the Pacific Ocean-a year-long journey through some of the most rugged terrain in the world- and their encounters with rain, wind, blizzards, bears, and their own emotional and spiritual demons. Erin and Hig set out from Seattle with a desire to raise awareness of natural resource and conservation issues along their route: clear-cut logging of rainforests; declining wild salmon populations; extraction of mineral resources; and effects of global climate change. By taking each mile step by step, they were able to intimately explore the coastal regions of Washington, British Columbia, and Alaska, see the wilderness in its larger context, and provide a unique on-the-ground perspective. An entertaining and, at times, thrilling adventure, theirs is a journey of discovery and of insights about the tiny communities that dot this wild coast, as well as the individuals there whom they meet and inspire.

Download or read book Sturgeon biodiversity and conservation written by Vadim J. Birstein and published by Springer Science & Business Media. This book was released on 1997-05-31 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

Download or read book Salmon People and Place written by Jim Lichatowich and published by . This book was released on 2013 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year wild Pacific salmon leave their oceanic feeding grounds and swim hundreds of miles back to their home rivers. The salmon's annual return is a place-defining event in the Pacific Northwest, with immense ecological, economic, and social significance. However, despite massive spending, efforts to significantly alter the endangered status of salmon have failed. In Salmon, People, and Place, acclaimed fisheries biologist Jim Lichatowich eloquently exposes the misconceptions underlying salmon management and recovery programs that have fueled the catastrophic decline in Northwest salmon populations for more than a century. These programs will continue to fail, he suggests, so long as they regard salmon as products and ignore their essential relationship with their habitat. But Lichatowich offers hope. In Salmon, People, and Place he presents a concrete plan for salmon recovery, one based on the myriad lessons learned from past mistakes. What is needed to successfully restore salmon, Lichatowich states, is an acute commitment to healing the relationships among salmon, people, and place. A significant contribution to the literature on Pacific salmon, Salmon, People, and Place: A Biologist's Search for Salmon Recovery is an essential read for anyone concerned about the fate of this Pacific Northwest icon.
