Chemoreception In Fishes

This book describes in general how the chemosensory systems of fish function at various levels. In many ways, fish are typical vertebrates differing only slightly from other vertebrates including humans. In other ways, their aquatic environment imposes strict requirements or offers unique opportunities which have resulted in some unusual functions having no counterpart in higher vertebrates. This new volume is necessitated by advances in many vital areas as the field of chemical senses continues to grow at a rapid pace. Most significant is the application of the contemporary electrophysiological technique of patch-clamping, recognition of a second messenger system in chemosensory transduction processes and the identification of hormonal pheromones in fish reproductive behaviour. The last major synthesis of our knowledge about fish chemoreception, Chemoreception in Fishes, was published ten years ago (Elsevier, Amsterdam, 1982). In that volume four aspects of fish chemoreception, Le. morphology of the peripheral chemoreceptors. primary sensory processes, roles in behaviour, and its interactions with environment, were discussed. This book is intended to be helpful to students, scientists and aquacul turists not only as a source book but also as a textbook on chemical senses.

Research on olfaction in fishes: historical aspects; Structure and function; Development and regeneration of the olfactory organ in rainbow trout; Comparative morphology of the peripheral olfactory organ in teleosts; Synaptic organization of the olfactory bulb and central projection of the olfactory tract; Taste organ in the barbel of the bullhead; Chemoreceptive mechanisms; Responses of olfactory receptor cells to electrical and chemical stimulation; High sensitivity and specificity of olfactory and gustatory receptors of catfish to amino acids; Structure-activity relationships of amino acids as olfactory stimuli; Biochemical aspects of amino acid receptors in olfaction and taste; Neuronal correlates of olfactory behavior in goldfish; The role of olfaction in the orientation of fishes; Chemoreception in the lateral-line organ; Role of chemoreception in feeding; Taste receptor stimulation and feeding behavior in the puffer; Chemical stimulation of feeding behavior; Identification of the gustatory feeding stimulants; Baits in fisheries with emphasis on the North Atlantic cod fishing industry; Role of chemoreception in social behavior and migration; Chemical signals in communication; The adaptive significance of the alarm substance-fright reaction system; The role of chemoreception in salmonid homing; Chemoreception and water pollution; Chemoreception and aquatic pollutants; Structure and function of the olfactory mucosa of migrating baltic trout under environmental stresses, with special reference to water pollution.

The senses of smell and taste in fish play a vital role in many aspects of fish behaviour including feeding, migration and breeding. The editor of this book, himself an internationally recognized authority on the subject, has drawn together an eminent group of contributors who provide a thorough synthesis of all aspects of the subject.

Provides interested readers with a current understanding of the biology of fishes as it relates to their utility in the laboratory.

This book deals with chemosensory systems of fishes and covers the well known olfactory and the gustatory senses as well as the less popular solitary chemosensory cells. Chemosenses play an essential role in the life of a fish. They help fish in their search for food, to consume it and digest it. They also help fish to find their conspecifics and t

New scientific approaches have dramatically evolved in the decade since The Physiology of Fishes was first published. With the genomic revolution and a heightened understanding of molecular biology, we now have the tools and the knowledge to apply a fresh approach to the study of fishes. Consequently, The Physiology of Fishes, Third Edition is not merely another updating, but rather an entire reworking of the original. To satisfy that need for a fresh approach, the editors have employed a new set of expert contributors steeped in the very latest research; their contemporary perspective pervades the entire text. In addition to new chapters on gas transport, temperature physiology, and stress, as well as one dedicated to functional genomics, readers will discover that many of these new contributors approach their material with a contemporary molecular perspective. While much of the material is new, the editors have completely adhered to the original’s style in creating a text that continues to be highly readable and perpetually insightful in bridging the gap between pure and applied science. The Physiology of Fishes, Third Edition, completely updated with a molecular perspective, continues to be regarded as the best single-volume general reference on all major areas of research in fish physiology. The Physiology of Fishes, Third Edition provides background information for advanced students as well as material of interest to marine and fisheries biologists, ichthyologists, and comparative physiologists looking to differentiate between the physiological strategies unique to fishes, and those shared with other organisms.
