Book Synopsis Ecology of Atlantic Salmon and Brown Trout by : Bror Jonsson
Download or read book Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. 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.
Download or read book Sea Trout written by Graeme Harris 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: The Brown trout displays widely divergent life history strategies involving, variously, usage of streams, rivers, lakes, estuaries and the sea. The sea trout is the full sea-going form, it is very common and competes with salmon for the position of the most sought after migratory salmonid in many countries. Its use of freshwater, estuaries and coastal waters gives it a unique position as a sentinel species of environmental quality across these habitats. Although a commercially and recreationally important fish species, the management and scientific knowledge about sea trout has often been overshadowed by a focus on the salmon. However the First International Symposium for the Biology, Management and Conservation of Sea Trout sought to address this when a group of world class experts convened to share their research and form the basis for this impressive volume, covering: Stocks and fisheries Genetics and life history Ecology and population dynamics Management of stocks and world fisheries Fisheries scientists and managers, fish biologists, aquatic biologists, ecologists, members of fish and wildlife agencies, government departments and libraries in universities and research establishments where fish and fisheries are studied and taught will find this book a fascinating exploration of the species and a valuable reference tool.

Download or read book Trout and Salmon written by Trevor Crisp and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important book contains a great wealth of practical information on trout and salmon, species of fish that are of huge scientific and commercial interest. The introductory chapters of Trout and Salmon cover the biology and environmental variables of importance when considering these species. Further chapters encompass current information on the ecology of salmon and trout, with particular emphasis on the definition and quantification, where possible, of their environmental requirements and limitations. Comprehensive coverage of the impacts of human activities on trout and salmon is included, together with important aspects of relevance when considering issues of species conservation and habitat restoration. The book concentrates on the two species of the genus Salmo with many references and comparisons with the genus Oncorhynchus. Conclusions drawn within the book apply to both genera and as such the book will have relevance for both Europe and North America as well as other areas where these genera occur. Trevor Crisp has written a book that will be of great interest and use to fish biologists and fisheries scientists, to aquatic biologists, conservationists, ecologists and environmental scientists. The book will be particularly valuable for those working in government environment agencies and fish and wildlife departments and to all those involved in the management of these important species, their fisheries and habitats.
Book Synopsis A Modern Dry-Fly Code by : Vincent C. Marinaro
Download or read book A Modern Dry-Fly Code written by Vincent C. Marinaro and published by . This book was released on 2015-10-16 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Merging a poetic reverence for the art of fly fishing with a wealth of practical information and technical advice, Vincent Marinaro's, A Modern Dry-Fly Code is the classic guide to dry-fly fishing. Originally written in 1950 as the sport was languishing for lack of innovation, this book helped bring about a fly-fishing renaissance on riverbanks across America. An ideal book for readers who share Marinaro's deep reverence for the fisherman's connection to the unspoiled natural world, A Modern Dry-Fly Code will have you yearning for the sound of running brook water, eager to try some of the author's legendary fly patterns, casting techniques, and scouting tips.The product of a lifetime of experience wading in the waters of the Letort, Big Spring, and other south Pennsylvania streams, A Modern Dry-Fly Code significantly changed the way American anglers think about dry-fly fishing. In addition to detailed information on matching hatches, trout behavior and biology, and where and when to cast which types of flies, Marinaro introduces several ideas of his own invention based on the results of his many experimental outings. Among the revolutionary ideas set forth in this book are Marinaro's 'minutiae', miniscule flies designed to imitate the dozens of tiny insects that swarm over the surface of the water as well as his thorax-style technique for crafting superb dry-flies.For beginners and expert fishermen alike, there is much wisdom to be gleaned from Marinaro's inventive and curious inquiry into the nature and practice of fly-fishing.

Book Synopsis Freshwater Fisheries Ecology by : John F. Craig
Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
