Download or read book Salmonid Fisheries written by Paul Kemp and published by John Wiley & Sons. This book was released on 2011-06-13 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salmonid Fisheries is a landmark publication, concentrating on river management, habitat restoration and rehabilitation, disseminating lessons learnt in relation to the intensively studied salmonids that are applicable to future interventions, not just for salmonid species but for other non-salmonid species, biota and ecosystems. The contents of this book are the product of the Atlantic Salmon Trust’s 40th Anniversary Conference, held in association with the Game and Wildlife Conservation Trust. Drawing together carefully-edited contributions from many of the world leaders in river restoration from academia, commercial management and government agencies, this important book highlights the need to view river management from the context of the catchment and to adopt an ecosystem-based approach to restoration. The book is broadly divided into two sections which discuss first, the status of current understanding concerning the relationship between lotic habitat management, the response of salmonid fisheries and the theory of river restoration, and secondly, the application of this to habitat management and river restoration. Salmonid Fisheries is an extremely valuable work of reference for fisheries managers, ecologists, environmental scientists, fish biologists, conservation biologists and geomorphologists. Libraries in all universities and research establishments where biological and earth sciences, and fisheries management are studied or taught should have copies of this book on their shelves. Contributions from a wide range of well known experts Published in association with the Atlantic Salmon Trust Habitat management is crucial for dwindling wild salmon populations Of great importance to aquatic ecologists and fisheries managers

Download or read book River Restoration written by Stephen Darby and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: River restoration projects are designed to recreate functional characteristics within a context of physical stability. They tend to focus on the development and application of geomorphic principles for river restoration design. Due to different models obtaining different results on the same problem, incomplete or absent data, and climatic/social/cultural changes, the designers and managers of such projects frequently face high levels of uncertainty. This book will provide a systematic overview of the issues involved in minimizing and coping with uncertainty in river restoration projects. A series of thematic sections will be used to define the various sources of uncertainty in restoration projects and how these show at different points in the life cycle (design, construction and post-construction phases) of restoration projects. The structure of the book will offer a rational theoretical analysis of the problem while providing practical guidance in managing the different sources of uncertainty. A wide range of case studies will be included from Europe, North America and Australasia

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: To describe the activity patterns of juvenile Atlantic salmon, I monitored the behaviour of 35 age-0+ (emerged from gravel in the spring) and eight age-1+ (emerged from gravel in the spring of the previous year) fish over an eight-week-summer field season. Active fish were visible on their home range whereas inactive fish were assumed to be sheltering. My data were consistent with the prediction of the Asset Protection Principle that larger individuals will take fewer chances in order to reduce risk of predation. Indeed, 1+ fish (larger and older) were more active at night than during the day, whereas 0+ fish were almost exclusively active during the day. In contrast to my expectations, however, daytime activity did not peak at the optimal water temperature of 17°C found in laboratory studies of other populations. Rather, the activity of 1+ fish peaked at 20.7°C, whereas the activity of 0+ fish continued to increase until 23°C and then leveled off between 23-27°C. Once individuals were active, season and light intensity were the variables that most influenced their foraging rate. There was considerable individual variability within an age-class in how fish responded to environmental variables. The causes of this individual variability and the consequences for growth deserve further study.

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.
