Book Limit Reference Points for Atlantic Salmon Rivers in DFO Gulf Region

Download or read book Limit Reference Points for Atlantic Salmon Rivers in DFO Gulf Region written by and published by . This book was released on 2018 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fisheries and Oceans Canada (DFO) Ecosystems and Fisheries Management Branch asked DFO Science to develop reference points for Atlantic Salmon that conform to “A fishery decision-making framework incorporating the Precautionary Approach”. That request followed on an action item associated with the implementation of the Wild Atlantic Salmon Conservation Policy to review benchmarks / reference points for Atlantic Salmon which conform to the Precautionary Approach (PA). This Science Response Report results from the Science Response Process of February 8, 2018 on Limit Reference Points for Atlantic Salmon rivers in Salmon Fishing Areas 15 to 18, DFO Gulf Region. This is a step in the development of the PA framework. Further work is required to complete the PA framework including the definition of the Upper Stock Reference point(s), harvest strategies, and harvest decision rules”--Context, p. [1].

Book The Atlantic Salmon in the History of North America

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. Appendix A: Historical methods of packing salmon.

Book The Atlantic Salmon

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.
