Book Synopsis Genetic Status of Atlantic Salmon in Maine by : National Research Council
Download or read book Genetic Status of Atlantic Salmon in Maine written by National Research Council and published by National Academies Press. This book was released on 2002-03-22 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atlantic salmon in Maine, once abundant but now seriously depleted, were listed as endangered under the federal Endangered Species Act (ESA) in November 2000. The listing covers the wild fish in eight Maine rivers as a single "distinct population segment." The controversy in Maine that accompanied the listing led Congress to request the National Research Council's (NRC's) advice on the science relevant to understanding and reversing the declines in Maine's salmon populations. The charge to the NRC's Committee on Atlantic Salmon in Maine included an interim report focusing on the genetic makeup of Maine Atlantic salmon populations. This is the interim report. Understanding the genetic makeup of Maine's salmon is important for recovery efforts, because the degree to which populations in Maine differ from adjacent populations in Canada and the degree to which populations in different Maine rivers and tributaries differ from each other affect the choice of recovery options that are most likely to be effective. This report focuses only on questions of genetic distinctiveness. The committee's final report will address the broader issues, such as the factors that have caused Maine's salmon populations to decline and the options for helping them to recover.

Download or read book Atlantic Salmon in Maine written by National Research Council and published by National Academies Press. This book was released on 2004-09-07 with total page 304 pages. 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.
Book Synopsis The Atlantic Salmon by : Eric Verspoor
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.

Book Synopsis Nature and Bureaucracy by : David Jenkins
Download or read book Nature and Bureaucracy written by David Jenkins and published by Taylor & Francis. This book was released on 2022-09-08 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book questions how bureaucracies conceive of, and consequently interact with, nature, and suggests that our managed public landscapes are neither entirely managed nor entirely wild, and offers several warnings about bureaucracies and bureaucratic mentality. One prominent challenge facing scientists, policymakers, environmental activists, and environmentally concerned citizens, is to recognize that human influence in the natural world is pervasive and has a long history. How we act, or choose not to act, today will continue to determine the future of the natural world. Western-style management of nature, mediated by economic rationality and state bureaucracies, may not be the best strategy to maintain environmental integrity. The question is, what kinds of human influence, conceived of in the widest possible sense, will produce ideal environments for future generations? The related question is, who gets to choose? The author approaches the problem of analyzing the mutual influence of human and natural systems from two perspectives: as an objective scholar investigating bureaucracies and natural systems from the outside, and over the last decade as an inside practitioner working in various roles in federal land management agencies developing policies and regulations involved in the control of natural systems. This book will be of great interest to students and scholars of natural resource management, policy and politics, and professionals working in environmental management roles as well as policymakers involved in public policy and administration.

Book Synopsis The President's Salmon by : Catherine Schmitt
Download or read book The President's Salmon written by Catherine Schmitt and published by Down East Books. This book was released on 2015-07-30 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every spring, for thousands of years, the rivers that empty into the North Atlantic Ocean turn silver with migrating fish. Among the crowded schools once swam the King of Fish, the Atlantic salmon. From New York to Labrador, from Russia to Portugal, sea-bright salmon defied current, tide, and gravity, driven inland by instinct and memory to the very streams where they themselves emerged from gravel nests years before. The salmon pools and rivers of Maine achieved legendary status among anglers and since 1912, it was tradition that the first salmon caught in the Penobscot River each spring was presented as a token to the President of the United States. The last salmon presented was in 1992, to George W. Bush.That year, the Penobscot counted more than 70 percent of the salmon returns on the entire Eastern seaboard, yet that was only 2 percent of the river's historic populations. Due to commercial over harvesting, damming, and environmental degradation of the fish's home waters, Atlantic salmon populations had been decimated. The salmon is said to be as old as time and to know all the past and future. Twenty-two thousand years ago, someone carved a life-sized image of Atlantic salmon in the floor of a cave in southern France. Salmon were painted on rocks in Norway and Sweden. The salmon’s effortless leaping and ability to survive in both river and sea led the Celts to mythologize the salmon as holder of all mysterious knowledge, gained by consuming the nine hazelnuts of wisdom that fell into the Well of Segais. The President's Salmon presents a rich cultural and biological history of the Atlantic salmon and the salmon fishery, primarily revolving around the Penobscot River, the last bastion for the salmon in America and a key battleground site for the preservation of the species.

Book Synopsis Biological Confinement of Genetically Engineered Organisms by : National Research Council
Download or read book Biological Confinement of Genetically Engineered Organisms written by National Research Council and published by National Academies Press. This book was released on 2004-02-20 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetically engineered organisms (GEOs) have been under development for more than 20 years while GE crops have been grown commercially during the last decade. During this time, a number of questions have cropped up concerning the potential consequences that certain GEOs might have on natural or managed ecosystems and human health. Interest in developing methods to confine some GEOs and their transgenes to specifically designated release settings has increased and the success of these efforts could facilitate the continued growth and development of this technology. Biological Confinement of Genetically Engineered Organisms examines biological methods that may be used with genetically engineered plants, animals, microbes, and fungi. Bioconfinement methods have been applied successfully to a few non-engineered organisms, but many promising techniques remain in the conceptual and experimental stages of development. This book reviews and evaluates these methods, discusses when and why to consider their use, and assesses how effectively they offer a significant reduction of the risks engineered organisms can present to the environment. Interdisciplinary research to develop new confinement methods could find ways to minimize the potential for unintended effects on human health and the environment. Need for this type of research is clear and successful methods could prove helpful in promoting regulatory approval for commercialization of future genetically engineered organisms.

Book Synopsis Aquaculture Law and Policy by : David L. VanderZwaag
Download or read book Aquaculture Law and Policy written by David L. VanderZwaag and published by Routledge. This book was released on 2006-10-16 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aquaculture industry is fast expanding around the globe and causing major environmental and social disruptions. The volume is about getting a 'good governance' grip on this important industry. The book highlights the numerous law and policy issues that must be addressed in the search for effective regulation of aquaculture. Those issues include among others: the equitable and fair assignment of property rights; the design of effective dispute resolution mechanisms; clarification of what maritime laws apply to aquaculture; adoption of a proper taxation system for aquaculture; resolution of aboriginal offshore title and rights claims; recognition of international trade law restrictions such as labeling limitations and food safety requirements; and determination of whether genetically modified fish should be allowed and if so under what controls. This book will appeal to a broad range of audiences: undergraduate and postgraduate students, academic researchers, policy makers, NGOs, practicing lawyers and industry representatives.
Download or read book King of Fish written by David Montgomery and published by Basic Books. This book was released on 2009-04-28 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The salmon that symbolize the Pacific Northwest's natural splendor are now threatened with extinction across much of their ancestral range. In studying the natural and human forces that shape the rivers and mountains of that region, geologist David Montgomery has learned to see the evolution and near-extinction of the salmon as a story of changing landscapes. Montgomery shows how a succession of historical experiences -first in the United Kingdom, then in New England, and now in the Pacific Northwest -repeat a disheartening story in which overfishing and sweeping changes to rivers and seas render the world inhospitable to salmon. In King of Fish , Montgomery traces the human impacts on salmon over the last thousand years and examines the implications both for salmon recovery efforts and for the more general problem of human impacts on the natural world. What does it say for the long-term prospects of the world's many endangered species if one of the most prosperous regions of the richest country on earth cannot accommodate its icon species? All too aware of the possible bleak outcome for the salmon, King of Fish concludes with provocative recommendations for reinventing the ways in which we make environmental decisions about land, water, and fish.
