Physiology And Ecology Of Fish Migration

Among the roughly 30,000 species of fish, migratory species account for only 165 species, but most of them are very important fisheries resources. This book presents up-to-date innovative research results on the physiology and ecology of fish migration. It focuses on salmon, eels, lampreys, and bluefin tuna. The book examines migratory behavior, spawning, and behavioral ecology.

Since the publication of The Migrations of Fish by Prof. Alexander Meek in 1916, a number of books have been published on this subject. However, most of these books only cover one type of migratory mechanisms. This book aims to overcome this drawback by presenting a comprehensive coverage of all life history strategies-potadromy, anadromy, catadrom

The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few meters, as in some coastal and stream dwelling fishes, to thousands of kilometers, as in eel. There are about 8,000 known species that migrate within lakes and rivers, usually for food on daily basis as the convenience of food varies from place to place and from season to season. Fishes also migrate to lay their eggs in places where oxygen concentration in water is more and where there is plenty of food for juveniles when they hatch from eggs.This book presents state-of-the-art research and reviews on the physiology and ecology of fish migration. It examines migratory behavior, spawning, and behavioral ecology. The book also focus on longer-distance migrations, not because short-distance and vertical migrations are ecologically or evolutionarily less important, but because long-distance migrations typically impose greater behavioral and physiological challenges on fishes than short ones. Most movement studies addressed questions related to reproductive biology, effects of environmental factors on movement, stocking, and habitat use. Movement-related knowledge gaps were identified through the literature synthesis and surveys. Future studies on emigration/ immigration of fishes through lake corridors, the dispersal of stocked fishes and of stock mixing were identified as being particularly important given their potential for developing lake- or region-wide harvest regulations and stocking strategies. The diversity of tools for studying fish movement across multiple years and various spatial scales gives researchers new abilities to address key science questions and management needs. Addressing these needs has the potential to improve upon existing fisheries management practices. It also details the main procedures and patterns allied with all migratory life history strategies, as well as the main issues associated with their conservation. This book is intended to provide up-to-date information to advanced graduate students and researchers.

Animal Migration, Orientation, and Navigation presents the various aspects of animal migration, including the evolution of migration, climatic and meteorological influences, and bioenergetics. This book discusses the physiological control, sensory systems, orientation and navigation, and biological clocks and phenology aspects of animal migration. Organized into five chapters, this book begins with an overview of the migration strategies of animals in the context of a space continuum. This text then explains the influence of short- and long-term climatic cycles on the spectrum of migratory patterns in nature. Other chapters consider the energetic requirements of different migration strategies and the energy stores of the migrants. This book discusses as well the physiological basis of animal migration, with emphasis on endocrinal findings on the timing and energetic aspects of different migration strategies. The final chapter deals with the mechanisms used in direction finding by migrating animals. This book is a valuable resource for biologists and ecologists.

Biology and Ecology of Fishes Immerse yourself in the world of fish ecology with the newest edition of this essential introduction The study of fish ecology has traditionally proceeded along two tracks: the first is more basic, concerned with the anatomy, physiology and theoretical ecology of fish, and the second is more practical, concerning itself with fish populations, management, and habitats. Many fish researchers have come to view this distinction as artificial, and to develop a new study of fish that combines both tracks in a single holistic approach. It has never been more critical for introductory textbooks to represent this combined study in order to prepare the next generation of fish biologists and fishery scientists. Biology and Ecology of Fishes meets this need with a textbook that incorporates both biology and population management. Beginning with a general introduction to aquatic life and ecosystems, this book covers anatomical, environmental, and ethological topics to give a thoroughly rounded view of its subject, promising to serve as the fundamental introduction to multidisciplinary fish studies. Readers of the third edition of Biology and Ecology of Fishes will also find: Detailed coverage of subjects including growth and bioenergetics, feeding and predation, mortality and recruitment and more Increased attention to stressors of fish populations and communities New and revised chapters that introduce quantitative methods and present emerging issues facing fish populations and communities Biology and Ecology of Fishes is a useful overview for advanced undergraduate and graduate students studying fish ecology or fishery biology, as well as a reference for researchers and professionals in fish ecology, fish population management, and related fields.

This volume presents and discusses present knowledge concerning the diadromous migration of salmonids. It groups elements ranging from ecology to cell biology, to provide the reader background knowledge for critical understanding of published literature and for design of experiments.
