Many fishermen will acknowledge that the brown trout (Salmo trutta) and the Atlantic salmon (Salmo salar) are the world’s most intriguing, beautiful and noble fish. Having evolved nearly fifty million years ago in the Eocene epoch, these two species are close genetic cousins and descendants that can be found in oceans, rivers, lakes, and streams across the entire world. The Brown Trout-Atlantic Salmon Nexus is a complete historical, scientific, artistic, culinary, and practical guide to understanding and appreciating these remarkable fish. Veteran author, guide, and adventurist Matthew Supinski first highlights the evolution and history of the brown trout, from its origins in Europe and the Eastern Hemisphere, to its first North American transplanting in 1883, to its spread across the globe. He then dives into the scientific and angling brilliance of the brown trout/Atlantic salmon lineage praising the two species’ remarkable adaptability and resilience. And finally, chapters on fly-fishing tactics, fly patterns, artistic appreciation, and culinary/foraging opportunities where they are found throughout the world, will give readers all the information they need to catch, admire and appreciate this magnificent piscatorial legacy. With more than 150 stunning photos, The Brown Trout-Atlantic Salmon Salmo Nexus is a must-have for every passionate fisherman, admirer, artist and culinary naturalist connoisseur to enjoy.

No matter if you’re a beginner or expert, there is always room to learn A licensed guide in the UK, John Symonds fishes with anglers of all talent levels, from rank beginners to experienced old-timers. He has seen the common mistakes that many fly fishers make and, over the years, has developed lessons that help anglers overcome their mistakes and really improve their fly-fishing prowess. In this book, Symonds teaches: Basic skills, from stringing your fly rod to tying on backing, fly line, leader, and tippet How to make casts for a variety of stream and lake conditions How to figure out what fish are feeding on, and then picking the proper imitation How to determine where fish are in lake or river Tips on using dry flies, nymphs, streamers, and caddis imitations And much, much more Symonds learned to fly fish through trial and error. As he did, he came to realize that finding good, basic information was difficult to come by. He fills that niche with this helpful little guidebook that is guaranteed to elevate your level of fishing.

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.

This book provides, for the first time, a synthesis of quantitative information on the ecology of the brown trout, including seatrout, and comparisons with closely related species such as Atlantic salmon, Pacific salmon, and rainbow trout. Much of this work, especially the case studies, is relevant to general problems in quantitative animal ecology as well as to fisheries management. One theme emphasized throughout is the development, testing, and use of realistic mathematical models as important tools for consecration and management of fish and other animals. The first eight chapters deal with: the global success of the polytypic brown trout; growth and energetics; natural selection and genetic differences between individuals and populations; population dynamics of both adults and juveniles; and detailed case studies of one sea-trout population in the English Lake District. The ninth chapter highlights the main conclusions that can be drawn from the earlier chapters and identifies remaining major gaps in knowledge. This volume will be of interest to all students of population ecology and fish biology, and especially to biologists engaged in managing fisheries. Few books illustrate so well the value of long-term studies in ecology.

The challenges that the world's running water systems now face have never been more numerous or acute; at the same time, these complex habitats remain absolutely crucial to human wellbeing and future survival. If rivers can ever be anything like sustainable, ecology needs to take its place as an equal among the physical sciences such as hydrology and geomorphology. A real understanding of the natural history and ecology of running waters must now be brought even more prominently into river management. The primary purpose of this textbook is to provide the up-to-date overview that students and practitioners will require to achieve this aim. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials. It builds on the physicochemical foundations of the habitat templet and explores the diversity and adaptations of the biota, progressing from the population and community ecology of organisms and linking them to ecosystem processes and services in the wider biosphere via the complexities of species interactions and food webs. These include water quality and patterns of river discharge, as well as aesthetics, waste disposal, and environmental health. While the book is not primarily focused on application per se, each chapter addresses how humans affect rivers and, in turn, are affected by them. A final, future-oriented chapter identifies key strategic areas and sets a roadmap for integrating knowledge of natural history and ecology into policy and management. The Biology and Ecology of Streams and Rivers is an accessible text suitable for both senior undergraduate and graduate students taking courses in both lotic and general ecology as well as more established researchers, practitioners, managers, and conservationists requiring a concise and contemporary overview of running waters.

This Intergovernmental Panel on Climate Change Special Report (IPCC-SRREN) assesses the potential role of renewable energy in the mitigation of climate change. It covers the six most important renewable energy sources – bioenergy, solar, geothermal, hydropower, ocean and wind energy – as well as their integration into present and future energy systems. It considers the environmental and social consequences associated with the deployment of these technologies and presents strategies to overcome technical as well as non-technical obstacles to their application and diffusion. SRREN brings a broad spectrum of technology-specific experts together with scientists studying energy systems as a whole. Prepared following strict IPCC procedures, it presents an impartial assessment of the current state of knowledge: it is policy relevant but not policy prescriptive. SRREN is an invaluable assessment of the potential role of renewable energy for the mitigation of climate change for policymakers, the private sector and academic researchers.

This contributed volume deals with the various aspects of freshwater microbiology including diverse habitats, associated microorganisms, their ecological interactions, and industrial applications. Freshwater ecosystems are dynamic natural resources, providing sources of potable water, food, animal habitats, and recreation. Perspectives of microbial dynamics in freshwater bodies, covered in this title, provide a comprehensive and systematic analysis of microbial ecology in these ecosystems. These microbes are at the hub of biogeochemical cycles (carbon, nitrogen, phosphorus, potassium, and other elements). Moreover, they are an integral part of the aquatic food web and control the quality of freshwater bodies. Chapters in this title also discuss the issue of pollution in freshwater bodies and put forward available strategies for eco-friendly solutions. The book is a perfect documentation of primary and secondary data-based information on the latest research findings, case studies, experiences, and innovations in the field of freshwater microbiology. The book is of great use to students, researchers, and professionals studying aquatic sciences.
