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 viewas major scientific challenges in ecological research on these species.

Covering not only brown trout, but also their close relatives, this book provides valuable information which is also relevant to animal ecology.The book highlights the global success of the species and provides a long-term case study of population dynamics of one population. It also considers growth and energetics, ecological differences between brown trout populations, natural selection and genetic differences between brown trout, and the mechanisms responsible for population regulation in juvenile trout.Emphasizing the value of such long-term studies to species management and conservation, the book stresses the importance of development, testing and use of realistic models when considering species such as brown trout.

Brown Trout: Biology, Ecology and Management

A comprehensive guide to the most current research, history, genetics and ecology of the brown trout including challenging environmental problems

The brown trout is an iconic species across its natural European distribution and has been introduced throughout the World. Brown Trout offers a comprehensive review of the scientific information and current research on this major fish species. While the brown trout is the most sought species by anglers, its introduction to various waters around the world is causing serious environmental problems. At the same time, introduction of exogenous brown trout lineages threats conservation of native gene pools of populations in many regions. The authors summarize the important aspects of the brown trout’s life history and ecology and focus on the impact caused by the species. The text explores potential management strategies in order to maintain numerous damaged populations within its natural distributional range and to ameliorate its impacts in exotic environments. 

The authors include information on a wide-range of topics such as recent updates in population genetics, evolutionary history, reproductive traits and early ontogeny, life history plasticity in anadromous brown trout and life history of the adfluvial brown trout and much more. This vital resource:

Contains the latest research on the biology and ecology of brown trout Includes information on phylogeography, genetics, population dynamics and stock management Spotlights the brown trout’s introduction to regions around the world and the serious environmental impacts Offers a comprehensive review of conservation and management techniques

Written for salmonid scientists and researchers, fishery and environmental managers, and students of population genetics, ecology and population dynamics, Brown Trout explores the most recent findings on the history, ecology and sustainability of this much-researched species.

This book contains a detailed and fully-illustrated guide to brown trout fishing, with information on equipment, techniques, common pitfalls, storing and cooking, and much more. Highly illustrated and full of helpful tips, "Angling for Brown Trout" will be of utility to both novice and seasoned angler alike, and would make for a worthy addition to collections of allied literature. Contents include: "The Joy of Trout Fishing", "The Brown Trout", "Rods, Reels, and Lines", "Casts and Flies", "Other Gear and Knots", "Wet Fly-Fishing", "Other Means of Catching the Brown Trout", "Where to Find the Fish", "Time and Weather", "Striking and Playing the Fish", "How to Cook and Eat Trout", et cetera. Many vintage books such as this are increasingly scarce and expensive. We are republishing this volume now in an affordable, modern, high-quality edition complete with its original artwork and text.

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.
