Bioenergetics is the study of balance between energy supply and energy expenditure and requires an examination of physiological processes through which energy is transformed in living organisms. Studies on the flow and allocation of energy in biological systems often have, as their ultimate goal, the construction of a budget describing the partitioning of energy within an individual or population. Such budgets are then used to make inference about physiology or ecology in particular explaining why an organism or population does what it is observed to do assuming that energy allocation is the overriding concern. Bioenergetic modelling is an alternative method for estimating feeding rates in a natural population. These models quantify the relationship between feeding rates and growth relative to temperature, body size and activity. Bioenergetic models have been applied to address ecological questions in a wide variety of taxa.

The Physiology of Crustacea, Volume I: Metabolism and Growth deals with the physiological aspects of metabolism and growth in hundreds of species and higher taxa of Crustacea. The book explores processes related to the morphology and development of crustaceans, from blood chemistry to feeding and nutrition, digestion, excretion, molting, autotomy, and regeneration. This volume is organized into 17 chapters and begins with an overview of crustacean biology and systematics as well as ontogeny and phylogeny. The book then discusses the metabolic requirements of crustacean respiration, the mechanisms of gas exchange, and respiratory transport. The next chapters focus on the biochemistry of animal pigments such as hemoglobin and melanin and the crustacean blood chemistry, blood flow, heart function, feeding mechanisms, and vitamin contents. The book also discusses the digestive system of crustaceans, along with osmotic and ionic regulation; the excretory system; the link between ecology and metabolism; and sex differentiation in Crustacea. This book is written primarily for biologists, physiologists, and zoologists, as well as advanced students and research workers who are interested in problems of comparative physiology.

About 90 per cent of the 10,000 known species of the Crustacea Decapoda live in oceans and adjacent coastal and estuarine regions, and most of them pass through a complex life history comprising a benthic (juvenile-adult) and a planktonic (larval) phase. The larvae show a wide array of adaptations to the pelagic environment, including modifications in their functional morphology, anatomy, the molting cycle, nutrition, growth, chemical composition, metabolism, energy partitioning, ecology and behaviour.;All these traits are reviewed in this volume, attempting to promote an integrated, multidisciplinary view of the biology of larval Decapoda and other crustacean taxa. Emphasis is placed on the lesser-known anatomical, bioenergetic and ecophysiological aspects of larval life, as morphology has already been extensively documented. Changes in biological parameters (for example, rates of feeding, growth, metabolism) are shown in successive developmental stages, within individual stages, and as responses to environmental factors. Particular attention is paid to interrelationships between intrinsic phenomena (molting cycle, organogenesis, growth) and the overlaying effects of extrinsic factors (for example, food, temperature, salinity, pollution). Concluding from the available data, major bias and gaps in present knowledge of larval biology are identified and discussed as to their potential significance in future research.

It is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.

Fish Nutrition, Fourth Edition is an up-to-date, authoritative presentation of all key elements of the nutrition of fish and crustaceans. As aquaculture is rapidly expanding, more than 200 herbivorous and carnivorous species occupy a diverse range of ecological niches, and have therefore evolved to utilize a wide array of food sources. This new edition highlights these differences and covers the complexity and challenges associated with fish nutrition, addressing nutrient requirements to produce high-quality, healthful and sustainable resources, the essential nutrients for fish species, including proteins and amino acids, vitamins, minerals and essential fatty acids, a feed quality assessment, and fish pathology. Led by a team of international experts, this edition provides readers with new information on the use of high-throughput technologies in fish nutrition research, the role of feeds on the community structure of the microbiome, and advances in essential nutrient requirements. - Features expansive updates to the previous edition, including a new chapter dedicated to diet analysis and evaluation - Addresses the roles of fish nutrition and feeds on sustainability and the environmental impacts of aquaculture - Covers basic nutritional biochemistry and applied nutritional topics

Environmental Adaptations examines the dynamic interaction between an organism and its external environment in order to emphasize the adaptive significance of its responses. Focusing on the adaptations of crustaceans, it bridges the gap between other volumes in the series which deal in detail with the functional machinery of crustaceans and those dealing with ecological, taxonomic, behavioral, and applied subjects. This book is divided into seven chapters. The first two chapters highlight the range of respiratory responses exhibited by crustaceans when subjected to various environmental factors. Chapter 3 summarizes the mechanisms by which crustaceans take up energy and food from the environment under fluctuating conditions. It also reviews the assimilation efficiencies of crustaceans and the predator-prey interaction. Chapter 4 deals with ionic and osmoregulation from the view of its interaction with the environment. It emphasizes the adaptive nature of chemical regulation that enables various crustaceans to inhabit waters ranging from hypersaline ponds to fresh water. Chapter 5 discusses how the various species are reproductively adapted to generate offspring in the tremendous diversity of habitats occupied by crustaceans. The last two chapters report on the specific adaptations of crustaceans to terrestrial and freshwater habitats. This book is a valuable source for zoologists, paleontologists, ecologists, physiologists, endocrinologists, morphologists, pathologists, and fisheries biologists, and an essential reference work for institutional libraries.
