Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries. This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.

The Atlantic salmon is one of the most prized and exploited species worldwide, being at the centre of a massive sports fishing industry and increasingly as the major farmed species in many countries worldwide. Atlantic Salmon Ecology is a landmark publication, both scientifically important and visually attractive. Comprehensively covering all major aspects of the relationship of the Atlantic salmon with its environment, chapters include details of migration and dispersal, reproduction, habitat requirements, feeding, growth rates, competition, predation, parasitsm, population dynamics, effects of landscape use, hydro power development, climate change, and exploitation. The book closes with a summary and look at possible future research directions. Backed by the Norwegian Research Council and with editors and contributors widely known and respected, Atlantic Salmon Ecology is an essential purchase for all those working with this species, including fisheries scientists and managers, fish biologists, ecologists, physiologists, environmental biologists and aquatic scientists, fish and wildlife department personnel and regulatory bodies. Libraries in all universities and research establishments where these subjects are studied and taught should have copies of this important publication. Comprehensive and up-to-date coverage of Atlantic Salmon Atlantic Salmon is one of the world's most commercially important species Backed by the Norwegian Research Council Experienced editor and internationally respected contributors

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

Rivers of North America, Second Edition features new updates on rivers included in the first edition, as well as brand new information on additional rivers. This new edition expands the knowledge base, providing readers with a broader comparative approach to understand both the common and distinct attributes of river networks. The first edition addressed the three primary disciplines of river science: hydrology, geomorphology, and ecology. This new edition expands upon the interactive nature of these disciplines, showing how they define the organization of a riverine landscape and its processes. An essential resource for river scientists working in ecology, hydrology, and geomorphology. Provides a single source of information on North America’s major rivers Features authoritative information on more than 200 rivers from regional specialists Includes full-color photographs and topographical maps to illustrate the beauty, major features, and uniqueness of each river system Offers one-page summaries help readers quickly find key statistics and make comparisons among rivers

There are more than 180 exotic species in the Great Lakes. Some, such as green algae, the Asian tapeworm, and the suckermouth minnow, have had little or no impact so far. But a handful of others—sea lamprey, alewife, round goby, quagga mussel, zebra mussel, Eurasian watermilfoil, spiny water flea, and rusty crayfish—have conducted an all-out assault on the Great Lakes and are winning the battle. In Lake Invaders: Invasive Species and the Battle for the Future of the Great Lakes, William Rapai focuses on the impact of these invasives. Chapters delve into the ecological and economic damage that has occurred and is still occurring and explore educational efforts and policies designed to prevent new introductions into the Great Lakes. Rapai begins with a brief biological and geological history of the Great Lakes. He then examines the history of the Great Lakes from a human dimension, with the construction of the Erie Canal and Welland Canal, opening the doors to an ecosystem that had previously been isolated. The seven chapters that follow each feature a different invasive species, with information about its arrival and impact, including a larger story of ballast water, control efforts, and a forward–thinking shift to prevention. Rapai includes the perspectives of the many scientists, activists, politicians, commercial fishermen, educators, and boaters he interviewed in the course of his research. The final chapter focuses on the stories of the largely unnoticed and unrecognized advocates who have committed themselves to slowing, stopping, and reversing the invasion and keeping the lakes resilient enough to absorb the inevitable attacks to come. Rapai makes a strong case for what is at stake with the growing number of invasive species in the lakes. He examines new policies and the tradeoffs that must be weighed, and ends with an inspired call for action. Although this volume tackles complex ecological, economical, and political issues, it does so in a balanced, lively, and very accessible way. Those interested in the history and future of the Great Lakes region, invasive species, environmental policy making, and ecology will enjoy this informative and thought-provoking volume.
