Salmon are one of the most popular and commonly eaten fish and are among the most important fishery resources in the world. They are born and die in fresh water but can live in both fresh water and seawater where they migrate between rivers and oceans, showing amazing abilities to home to their natal stream precisely. However, their dynamic life cycles and mysterious abilities of natal stream imprinting and homing migration are not well understood. Physiological Aspects of Imprinting and Homing Migration in Salmon: Emerging Researches and Opportunities is a pivotal reference source that introduces the dynamic and complicated life cycle of salmon connected with fish migration and climate changes and presents physiological mechanisms of natal stream imprinting and homing in salmon with special references to hormone, olfaction, memory, and behavior. Additionally, salmon resources concerning salmon commercial fisheries, aquaculture, and global propagation systems are discussed. This book is ideally designed for ichthyologists, environmentalists, pisciculture professionals, fisheries, marine biologists, scientists, researchers, academicians, and students seeking coverage on one of the most integral species of fish in the world.

This is an entirely new revision, expanded and updated by Dr Morris to take account of recent research and controversial issues (including evidence that probably the greatest threat to hedgehogs comes from the rapidly expanding badger numbers - supported by research results published as recently as April).The book is illustrated throughout with cartoon and fine line drawings by renowned wildlife artist Guy Troughton. This special edition also features a gallery of the author's photographs. Pat Morris is this country's leading hedgehog expert. Having studied them for over forty years, he has probably published more scientific papers on the European hedgehog than anyone. He is President of the British Hedgehog Preservation Society, which recently celebrated its 30th year, and is an establishedwriter and broadcaster, often appearing on television and radio wildlife programmes.
