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.

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.

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 synthesiws of quantitative information on the ecology of the brown trout, including sea-trout, and comparisons with closely related species such as the 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 conservation and management of fish and other animals. - ;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. -
