Odeh (Conte Anadromous Fish Research Center) presents 13 contributions which explore the technical possibilities of constructing effective fish bypass systems for hydroelectric dams, especially those that are due for relicensing in the context of new regulations. The articles consist of case studies in the effectiveness of such techniques as surface bypass systems, modular inclined screens, hydroacoustic evaluation of fish entrainment patterns, surface collection, surface spill gates, and radio-tagging and radar tracking behavior evaluation strategies.

Recent studies have increasingly demonstrated the widespread existence of spatio-temporal variations in the abundance and distribution of species of freshwater fishes, previously assumed not to move between habitats. These movements are often on a seasonal or ontogenetic basis, for spawning, feeding and refuge, and in many cases are fundamental for the successful completion of lifecycles. This important book provides a single source for a range of previously widely dispersed information on these movements of fish in fresh waters, covering potamodromous fishes as well as the more familiar diadromous species, worldwide. Contents include full descriptions of types of migration and spatial behaviour, the stimulus and capacity for fish to migrate, the effects of climate on patterns of migratory behaviour, a taxonomic analysis (mostly by family) of freshwater fish migration, methods for studying migration, and details of the impacts of man's activities on freshwater fish migration. Migration of Freshwater Fishes provides an excellent and comprehensive reference to which the river manager, biologist or student can now refer to obtain information, advice and current opinion on the migratory behaviour of most taxonomic groups of fishes occurring in fresh water. University libraries and aquatic research stations should also have copies of this essential reference book on their shelves. Well-known international authors. Of great commercial importance to fisheries and professional angling bodies. Draws together much new information in one place. Detailed review of world wide migratory behaviour for most groups of freshwater fishes. Pure and applied relevance, for academics, fisheries scientists, river managers and conservationists. This comprehensive book includes 67 tables and figures and over 1,400 references.

Researchers and managers of regulated river systems will find this volume useful in acquiring information for deciding an integrated management plan for regulated river operations. Rather than the ecological theory of impacts of flow regulation, emphasis has been placed on methods to predict water quality and habitat alterations, as well as techniques to mitigate impacts from various operational scenarios. Although most chapters refer to impacts of riverine impoundments, these alternatives apply to any regulated situation in which changes in water quality or flow pattern occur. The predictive modeling techniques are explained primarily from a theoretical background. However, extensive bibliographies can guide the uninitiated to specific texts and software. Where controversial techniques have been presented, alternate methods are also described. Major topic areas include water quality problems, channel modification and management, ecological modeling and management, as well as a section on perspectives for ecological management and special problems in developing nations.

The current high demand for fish and increased awareness of the role of the environment in supporting human well being has led to a situation where attitudes to inland water resources are changing rapidly. Trends in resource use and environmental impact are very evident in inland waters which are particularly vulnerable as they act as collectors of all the activities occurring in their basins and rank as some of the most endangered ecosystems in the world. The principle changes influencing the evolution of the aquatic resource for fisheries are described in this book, which has been compiled for the Food and Agriculture Organization of the United Nations.

This volume comprises the proceedings of the 5th International Symposium on Shallow Lakes, held at Dalfsen, The Netherlands, in June 2005. The theme of the symposium was Shallow Lakes in a Changing World, and it dealt with water-quality issues, such as changes in lake limnology, especially those driven by eutrophication and pollution, increased nutrient loading and productivity, perennial blooms of cyanobacteria and loss of biodiversity.

Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
