Ecology of Atlantic Salmon and Brown Trout by Bror Jonsson,Nina Jonsson Pdf

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.

Physiological Ecology of Pacific Salmon by Cornelis Groot Pdf

Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.

Atlantic Salmon in Maine by National Research Council,Division on Earth and Life Studies,Ocean Studies Board,Board on Environmental Studies and Toxicology,Committee on Atlantic Salmon in Maine Pdf

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.

Salmon by P. T. K. Woo,Donald J. Noakes Pdf

This book provides a good mix of both basic and applied topics in the hope that it will be useful and of interest to scientists working on finfish. It has 15 chapters written by 27 contributors and many of them are highly respected scientists. Given the global importance of salmon, contributors are from many countries including 11 from Japan and Russia. These authors bring slightly different and important perspectives to the book, and their expertise and research may not be known to many young scientists in Europe and in the Americas. The volume starts with an overview of salmon, their economic and social importance, and their impacts on the environment. Subsequent topics include morphological, physiological and behavioural differences between wild and farmed salmon; growth, food utilisation and water flow requirements of wild and hatchery salmon; the real and potential ecological impacts of sea cages and hatcheries; the potential use of waste product (gelatine) from the salmon industry; salmon behaviour and genetics including their broad applications that contribute to our understanding of fish biology, and nutritional and anti-nutritional factors in salmon culture. There are also chapters on environmental impacts and the economic importance of the commercial fishery and salmon farming industry; these are very important components of the industry, especially to the seafood sector.

Trout and Salmon by Trevor Crisp Pdf

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.

Salmon at the Edge by Derek Mills Pdf

Salmon at the Edge covers, in depth, the problems faced by wild Atlantic salmon and sea trout in estuaries and coastal zones, and in their early weeks at sea. The book also reflects the current precarious state of many migratory salmonid populations and the need for new approaches to a number of threats to these populations. Generated from papers given at the landmark Sixth Atlantic Salmon Symposium, held in Edinburgh, UK, Salmon at the Edge contains a huge wealth of information on such important topics as the impact of salmon farming, the behaviour of post-smolts in their early migration and their vulnerability to by-catch, and the use of nutrient enrichment and habitat enhancement to increase production of juvenile salmonids. With chapters written by internationally-known and respected authors, and including a message of support from His Royal Highness The Prince of Wales, this important volume is essential reading for all those involved with salmonid fishes, including fish biologists, fisheries scientists and managers, environmental, marine and freshwater scientists, and personnel involved in salmon aquaculture. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves. The Sixth Atlantic Salmon Symposium, from which chapters in this book have been generated, was organised by The Atlantic Salmon Trust and The Atlantic Salmon Federation, and was published with the financial support of The Fishmongers’ Company and Scottish and Southern Energy. Derek Mills of The Atlantic Salmon Trust, Pitlochry, Perthshire, UK has many years of research, writing and editing experience in salmon biology and fisheries
