Book excerpt: Atlantic salmon (Salmo salar, L) is an anadromous species contributing to major fishery catches and comprising a significant part of the aquaculturally produced fish for human consumption. The aim of this book is to incite the interest in the field of knowledge gathered from a broad scope of disciplines that have investigated this fish species. Und
Download or read book The Atlantic Salmon written by Eric Verspoor and published by John Wiley & Sons. This book was released on 2007-05-21 with total page 532 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.

This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.

Crowley and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Farmed Atlantic Salmon (Salmo salar) have experienced multiple generations of selection pressures different from those experienced by their wild counterparts. Farmed fish escape from aquaculture facilities regularly, and their interbreeding with wild fish can result in lower wild population productivity and altered life history traits. Therefore, understanding the genetic basis of relative performance of farmed, wild, and hybrid salmon is critical to predicting impacts on wild populations from farmed escapees. In my first data chapter, I compared the relative survival, size, morphology, and parr marks of Atlantic Salmon parr (wild, farmed, and reciprocal F1 hybrids) over the first summer of growth at three replicate sites in southern Newfoundland. There was a consistent pattern of relative survival across all sites (wild-mother hybrids > pure wild > pure farmed > farmed-mother hybrids), with wild fish consistently smallest in size, and wild-mother hybrids and farmed fish largest. In addition, I found small differences in body shape related mainly to body depth, and differences among sites for parr mark size. In my second data chapter, I compared lipid and fatty acid profiles at release and recapture for farmed, wild and hybrid parr. There were lipid profile differences among cross types at both time points and in addition, pure farmed fish displayed a greater decrease in storage lipids and certain fatty acids characteristic of freshwater invertebrate prey over the experimental period when compared with other cross types. Overall, there were measurable differences in survival and fitness-related traits among cross types, even over a relatively short experimental period under favourable conditions. Ultimately, this research provides key data on relative cross type performance for North American populations of Atlantic Salmon that may help inform predictive models, and subsequent aquaculture management and mitigation decisions.

This book was released on 2004 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene and genome duplications have played a major role in vertebrate evolution. Salmonids provide a useful resource for studying the consequences of these events as their common ancestor underwent a genome duplication between 25 and 120 miliion years ago. To understand how a genome reorganizes itself to cope with duplicated chromosomes and the importance of gene duplications for evolution and adaptation, homeologous regions of the Atlantic salmon genome were identified and studied within a large insert, genomic BAC library; these BACs contain the metallothionen event. A BAC from each region was subsequently shotgun subcloned and sequenced. Sequence analysis revealed the presence of 10 genes, retaining their collinearity between the BAcs, although pseudogenization events have occurred in one of the duplicate loci in two instances. Comparative genomic analysis revealed the existence of extraordinary conservation of syntney over time.
