Migration Of Freshwater Fishes

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.

Since the publication of The Migrations of Fish by Prof. Alexander Meek in 1916, a number of books have been published on this subject. However, most of these books only cover one type of migratory mechanisms. This book aims to overcome this drawback by presenting a comprehensive coverage of all life history strategies—potadromy, anadromy, catadromy, amphidromy and oceanodromy in one book. The first section of this book reviews the history of fish migration studies, the main definitions and concepts related with fish migration and the main trends and challenges of fish migration research. The second section describes the main processes and patterns associated with all migratory life history strategies, as well as the main problems associated with their conservation. Finally, the third section provides examples of the main methodologies used to study fish migration. This book was conceived with the objective to provide undergraduate and graduate students and researchers with a comprehensive book on which they could rely.

Migration - a problem of definition; Patterns of migration; Orientation; Bioenergetics; Physiology; Ecology and evolution.

The Behavior and Ecology of Pacific Salmon and Trout explains the patterns of mate choice, the competition for nest sites, and the fate of the salmon after their death. It describes the lives of offspring during the months they spend incubating in gravel, growing in fresh water, and migrating out to sea to mature. This thorough, up-to-date survey should be on the shelf of everyone with a professional or personal interest in Pacific salmon and trout. Written in a technically accurate but engaging style, it will appeal to a wide range of readers, including students, anglers, biologists, conservationists, legislators, and armchair naturalists.

Fish migration is important and spectacular. Migratory fish gather energy in one portion of the environment and transport it to other areas, where it often becomes available to humans or to other elements in the ecosystem. Migration brings fish into situations that allow easy harvest as they concentrate along migration routes. Their journeys also make them vulnerable to human intereference at critical points along their route. Salmon, for example, may harvest plankton in the open ocean and transport that food energy to coastal and inland regions, where it is captured by fisheries or deposited in inland streams and utilized by the flora and fauna of the region. These salmon are able to complete journeys of thousands of kilometers from their natal streams to oceanic feeding grounds and back to the same home streams, an accomplishment that strains our credi bili ty . We now understand some of the timing and guiding stimuli used in these migrations, and mechanisms can be logically proposed, on the basis of the established abilities of fishes, to account for the unexplained portions of the migrations. There is no single factor guiding these fish. Instead, they are dependent on the presence in their environment of a great variety of appropriate orienting and timing stimuli. These stimuli are vulnerable to human interference. The more widespread and easily available the information on these requirements, the more readily fish can be protected from such interference.

This book describes the fish which exhibit diadromy, their life history strategies and the implications for fisheries. The book should therefore represent an important volume for workers in fish biology, animal physiology and behaviour, and fisheries.
