"Fish physiology refers to the scientific study of how the component parts of fish function together in the living fish. There is an obvious and increasing trend toward multidisciplinary approaches to understanding physiological research, incorporating the many fields of biology to begin to understand more fully the impact of anthropogenic contamination of the aquatic ecosystem. This book provides comprehensive coverage of research and reviews on varied aspects of fish and fisheries biology. It presents the recent advances in fish physiology and discovers ecological, behavioral, and molecular approaches to fish physiology. It includes articles on any field of fish biology where the emphasis is placed on adaptation, function or exploitation in the whole organism. The large numbers of the wide variety of topics that covered in this book, highlight the growing enthusiasm for integrating different fields of research and the importance of this approach in aquatic physiology. Fish have become the most widely used model for studies of biosynthesis and processing of the pancreatic hormones. The situation has changed remarkably during the last decade. In this work the contemporary status of physiological studies on the fish pancreas is also outlined. This volume aimed to draw together internationally researchers whose research focuses on the interactions between behaviour, physiology and toxicology in fish. This book will be of great need for aquatic biologists, ichthyologists, fisheries scientists, and comparative physiologists. "
