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.

This book was released on 2012 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Current knowledge of the Atlantic salmon (Salmo salar L.) marine distribution is based primarily on mark-recapture programs initiated in Europe and North America since the end of World War II. The discovery of non-native Atlantic salmon off Greenland prompted the initiation of a US Carlin tagging program in 1962, which revealed vast ocean transits to Canada and Greenland. Since its inception, over 1.5 million fish from New England rivers, primarily hatchery reared smolts, have been tagged and released. Carlin tag recoveries numbered 8,542 with a resulting recovery rate of 0.52%. Just over half (50.8%) of the recoveries have been in US waters (both freshwater and marine), primarily as pre-spawned adult river returns, while the remainder in distant waters off Atlantic Canada (23.2%) and Greenland (26.0%). A Coded Wire Tag (CWT) program was also initiated in the early 1980s to complement the Carlin tagging program. Since its inception, over 6 million tagged Atlantic salmon have been released. CWT recovery rate has been low compared to the Carlin tags given the requirement of trained operators and specialized detection equipment to identify tags. A total of 420 CWT tags were recovered in distant waters of Canada (22.9%) and Greenland (77.1%) through sampling efforts in fish processing plants. This report documents the US Atlantic salmon Carlin and CWT tagging programs, describes the current state of the two databases, and presents summary statistics of the resulting datasets"--Abstract.

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.

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.

This book was released on 1992 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study reviewed available information on the recovery of tagged adult salmon to determine which factors influence the survival of hatchery-reared smolts. Sixty-nine groups of 2+ Atlantic salmon smolts and 27 groups of 1 or more smolts produced at the Mactaquac FCS were marked with modified Carlin tags and released in the Saint John River, New Brunswick, from 1973-88. During the same period, 35 groups of tagged 1 or more smolts produced at the Mersey FCS were released in the LaHaye River, Nova Scotia. The numbers of tagged adult salmon that were later recovered in distant and local commercial fisheries, in Native food fisheries, by anglers and at collection facilities operated by the Dept. of Fisheries and Oceans provided a measure of the survival rate of the various smolt groups.
