DescriptionSalmonid 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.
