Aquaculture has gained a momentum throughout the world during recent decades which is unparalleled in other branches of food production. This book describes methods currently used for the production of those warm water table fish which are of major importance. Included are experiments and procedures which will help to combat the growing food problem through new production methods for animal protein. The aim of the work presented here is to promote the continuous production of warm water table fish independently of climate or environment within the least necessary space and even in regions with unsuitable weather or topography.

Ecosystem analysis and ecological modelling is a rapidly developing interdisciplinary branch of science used in theoretical developments in ecology and having practical applications in environmental protection. In this book, the authors introduce new holistic, particularly cybernetic, concepts into ecosystem theory and modelling, and provide a concise treatment of mathematical modelling of freshwater ecosystems which covers methods, subsystem models, applications and theoretical developments.Part I begins with a brief introduction to the principles of systems theory and their applications to ecosystems, and provides a summary of various methods of systems analysis. In Part II emphasis is laid on the pelagic processes in standing water, characterised by relatively uninvolved structures from which models can be readily developed. Part III describes applications of the technique of modelling to solutions of theoretical and practical problems, with different modelling methods and objectives being used in the various chapters. More recent developments in the methods and theory of ecosystem modelling are covered in Part IV which also includes a discussion of future trends. The book is addressed to practising ecologists and engineers in the fields of ecology, limnology, environmental protection, and water quality managements, as well as to graduate/post-graduate university students in science and engineering. Students and researchers involved in environmental applications of mathematics and cybernetics will also find the book of interest.

The Gray Whale: Eschrichtius robustus provides an introduction to the understanding of Eschrichtius robustus or the gray whale. This book explores the life processes, reproduction, and growth of large cetacean populations. Organized into four parts encompassing 25 chapters, this book begins with an overview of the gray whale evolution, fossils, and subfossil remains, range, and systematics in historical times. This text then presents the historical of gray whale exploitation and the economic importance of these whales to humans. Other chapters consider the gray whale migration, abundance, and seasonal distribution in the wake of the California population's recovery from depletion. This book discusses as well the methods used in shore-based censuses during migration and in aerial surveys of gray whales taken on their winter grounds. The final chapter deals with some innovative approaches to the study of free-ranging cetaceans. This book is a valuable resource for anthropologists, paleontologists, biologists, and naturalists.

This two-volume work presents a summary and review of the current state of lobster biology, ecology, physiology, behavior, and management. It emphasizes the biology of clawed lobsters (Nephropidae) and spiny lobsters (Palinuridae), with attention also given to slipper lobsters (Scyllaridae) and coral lobsters (Synaxidae).The first chapter of Volume 1 provides an overview of the general aspects of lobster biology that serves as an introduction for readers of both volumes. Subsequent chapters examine the topics of growth, neurobiology, reproduction, nutrition, pathology, social behavior, and migration patterns.The chapters in Volume II consider the ecology, population dynamics, fishery biology, and aquaculture of spiny and clawed lobsters. The topics selected in both volumes represent areas of current research whose findings have not been previously synthesized into a coherent form.An important feature of these volumes is the emphasis on the interaction between biology and management and culture. Many of the contributors have done research in both applied and basic biology and can articulate both points of view. The interaction between basic and applied research is of fundamental importance in these volumes in which management aspects of the research have been integrated with the basic biology of lobsters.The Biology and Management of Lobsterswill be of interest to crustacean biologists, marine biologists and ecologists, zoologists, physiologists, animal behavior researchers, aquaculturalists, fisheries biologists and managers of fisheries, neurobiologists, pathologists, and food scientists.
