The book, Electrophysiology and Fish Behavior embraces 19 chapters having two main parts, namely, electrophysiology and fish behavior. In the first part, the history and behavior of electric fishes were traced out together with the application of electricity for catching fishes. The response of fishes in an electric field and the physiological mechanisms and electrical principles involved in it were correlated thereafter. The empirical studies on the reactions of cold water fishes, warm water Indian and marine fishes and the hybrids in different forms of electrical field (DC, AC, Pulsed DC, Rectangular and Square wave form) by various investigators have been described in details along with the physical, chemical, biological and environmental factors responsible for the intensity of such reactions. The effect of electrical stimulation on the heart beat and body muscle of fish were determined and recorded in the book together with the harmful effect of electric exposure on fertilized and developing eggs, hatchlings, juveniles, older fishes and the man who handles the electric current during investigation and research in the laboratory and field. In the second part of the book, role of olfaction in fish behavior, especially for feeding, stimuli associated with danger, reproductive cues and social interaction been highlighted. Fish behavior in aquarium (in captivity) and in the wild describing their adaptation in different ecosystems were documented in the relevant chapters of the book. Diversity of fishes in different ecosystems and their cooperative behavior with special stress on learning and memory were given in the book. In the last chapter, examples were putforth for applied fish behaviors. The book will be useful for the students, teachers and researchers working on this line.

Fish are extremely successful vertebrates. Because of a long and divergent history they are now found in almost every conceiv able aquatic habitat. This radiation has been accompanied by great diversity in structure, physiology, and behaviour. Despite this variability, fish must solve a number of basic problems that are common to all animals. The most important of these are: (1) to find and ingest appropriate food; (2) to avoid predation; and (3) to reproduce. The main purpose of this book is to describe the variety of behavioural strategies that fish use in coping with these problems. My approach has been to draw together material from both field and laboratory work that is widely scattered in the litera ture. The major emphasis is on field studies, since my main concern is with adaptive solutions to problems, and I believe these are most likely to be correctly perceived by workers who are familiar with the natural ecological setting of their animals. Of course, many details of behaviour cannot be seen and quantified adequately in the field, and therefore I have not ignored laboratory studies. However, even here I have concen trated on work that illustrates the variety of solutions that fish use to solve the three basic problems. Much important work, for instance on causation, development, and learning, is not included.

Fish sensory systems have been extensively studied not only because of a wide general interest in the behavioral and sensory physiology of this group, but also because fishes are well suited as biological models for studies of sensory systems. Fish Physiology: Sensory Systems Neuroscience describes how fish are able to perceive their physical and biological surroundings, and highlights some of the exciting developments in molecular biology of fish sensory systems. Volume 25 in the Fish Physiology series offers the only updated thorough examination of fish sensory systems at the molecular, cellular and systems levels. - Offers a comprehensive account of the present state of science in this rapidly expanding and developing field - New physiological techniques presented to enable examining responses at the cellular and system levels - Discusses fish sensory systems and how they have adapted to the physiological challenges presented by an aquatic environment

Some fishes test their environment by generating electric fields outside their bodies (man's first contact with electricity). To send and receive electric signals, one's own or those from a neighbor, is the basis of some bony fishes' unusual sensory capacities that enable them to lead a secret, nocturnal life. This volume provides the reader with a detailed account of these fishes' biology and behavior and their sophisticated sensory capacities. The phylogenetic relationships of the fish taxa involved are discussed as well as the physiology and anatomy of the electrosensory-motor-system and the integration to form an efficient intelligence system. The main emphasis is on the descriptive and experimental analysis of electric communication behavior in a variety of species, including studies of digital signal synthesis. Whenever possible, mechanisms of communication are indicated.

As in the bestselling first edition, The Physiology of Fishes, Second Edition is a comprehensive, state-of-the-art review of the major areas of research in modern fish physiology. This Second Edition is entirely revised, with 17 of the 18 chapters written by new authors. It also includes four entirely new chapters:

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.

Heiligenberg's pioneering research describes the behavior of one species, the jamming avoidance response in the electric fish Eigenmannia, providing a rich mine of data that documents the first vertebrate example of the workings of the entire behavioral system from sensory input to motor output. Neural Nets in Electric Fish presents the principles and detailed results that have emerged from this exciting program. Heiligenberg's introduction familiarizes the reader with the unusual sensory modality electroreception, demonstrating the rationale and the motive behind the research. The text, which includes many helpful new pedagogical graphs, takes up the behavioral work done in the early 1980s, from explorations of peripheral receptors, the hindbrain, the midbrain, and finally diencephalon, to the most recent studies of motor output. Neural Nets in Electric Fish clearly describes Heiligenberg's analysis of the complex nature of the electrical stimulus delivered to Eigenmannia during jamming avoidance, and explains the novel two-parameter notation he uses to represent the different stages in information processing, giving many examples of the notation's power. The book relates all known behavioral phenomena of the jamming avoidance response to specific properties of the underlying neural network organization and draws interesting parallels between the electric sense and other sensory processing systems, such as the barn owl's sound localization system, motion detection systems in vision, and bat echolocation.
