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. more...

Diseases are a major threat to the sustainability of the aquaculture industry. Because antibiotics have many drawbacks, increasing importance is being placed on understanding the mechanisms that make nutrition a key factor in host defense against pathogens. Nutrition and Fish Health is the first book to provide comprehensive information on nutrition as a means to improve fish health and defend against infection. more...

While new molecular techniques hold great promise for application in commercial aquaculture in the future, most aquaculture currently takes place under practical and often challenging conditions. Tremendous gains could be realized in most forms of aquaculture through the application of more traditional and practical approaches to genetic improvement, as detailed in this timely book. Practical Genetics for Aquaculture provides reviews of the fundamental theory and examples of practical applications for numerous aspects of genetic improvement in aquaculture. Contents include thorough details of genetic concepts and terminology, chapters on genetic change for numerous traits and the resultant increased yields and profitability, control over reproduction, the development and performance of transgenic aquatic organisms and finally a chapter devoted to potential risks to aquatic habitats and populations posed by all forms of genetically improved cultured species. Written in a user-friendly and succinct style by Dr C. Greg Lutz, who has many years' experience teaching, researching and refining practical applications, this exciting and useful book is a vital source of commercially important information to the aquaculture community. Personnel involved in aquaculture including fish farmers, teachers, students and researchers will find this book invaluable and it should be made available on the shelves of all libraries in government departments, universities and research establishments where aquaculture is practised, studied or taught. C. Greg Lutz is Specialist and Professor of Aquaculture with Louisiana State University, Baton Rouge, Louisiana, USA more...
