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.

Available in PDF, EPUB and Kindle. Book excerpt: CHOICE 'Highly Recommended for all readers' June 2021 Vol. 58 No. 10 This stunningly illustrated book goes far beyond a run-of-the-mill nature guide. It explores the fascinating life histories of Britain’s freshwater fishes, a group of animals which, despite their importance and ubiquity in our diverse still and flowing fresh waters, has before now been rarely regarded and respected as 'wildlife'. Our native fishes tend generally to be considered as simply something for anglers to catch or for people to eat, yet they work enormously hard for us. Author Mark Everard, avid nature-watcher, angler and scientist, shows how freshwater fish provide food, ornamentation, sport and cultural identity, and highlights their huge importance for conservation as part of the living ecosystems upon which we all depend. He dives into the mysteries moving below the surface of our rivers and lakes, bringing the wonderful and fascinating world of the diversity of British freshwater fish species into plain sight and into mind. This unique book features over 100 full-colour photographs by pioneering photographer and filmmaker Jack Perks, whose work has featured on BBC Springwatch, The One Show and Countryfile. The book is filled with technical detail useful to conservationists and biology students. Most importantly, it is also presented in an accessible, visually attractive and engaging manner that will appeal to anybody with an interest in the natural world: the conservation-minded public, the angling community, and our nation of wildlife enthusiasts. Whatever your background, this book will open your eyes to our freshwater fishy wealth, and the many ways in which it enriches our lives.

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

Available in PDF, EPUB and Kindle. Book excerpt: As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology.The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.
