Understanding the biology of the innumerable number of aquatic species on our planet is the focus of sustained research efforts. Environmental degradation, management or rehabilitation of wild stocks, and the forecasted climatic changes are fueling interest in the study of the ecology, feeding behavior, and nutrition of aquatic animals in their natural habitat. In parallel, the rapid expansion of aquaculture in many parts of the world has supported vigorous research programs on nutrition, and feeding of cultivated aquatic organisms. More than 250 aquatic species are cultivated on a commercial scale using a wide variety of production systems. This great diversity results in great opportunities and tremendous challenges. Topics covered in this book are as diverse as, feeding ecology of fish in their natural habitat, feeding behavior, digestive anatomy, biochemistry and physiology of different fish species at different life stages, the impact of diet on gastro-intestinal development and health, nutrition and disease resistance, and modeling conversion of food or feed inputs into biomass.

Fishes are by far the most species-rich vertebrate taxon, and it is also the vertebrate group with the most strikingly diverse repertoire of behaviours and behavioural adaptations. As such, they provide us with many opportunities to explore the fascinating complexities of animal behaviour. Central questions addressed in this book include: How do sensory input, hormones, genetics and experience interact to shape individual behaviour? What should a fish do to be in the right place at the right time and how should it behave to be an efficient predator yet not become the subject of predation itself? How to find a mate or to find the best mate? Should all fish do the same, or is the optimal behaviour dependent on individual characteristics? How does reproductive behaviour affect what fish look like, in terms of colour, body form or body size? And how do fish cope with their complex social and biological environment, including parasites, competitors and collaborators? This new book provides an exciting overview of the many new insights offered by recent research on fish behaviour. The chapters are written by prominent international scientists and are aimed not only at fish biology students and researchers but anyone interested in the interplay between behaviour, ecology and evolution.

Among all vertebrates, gobies are second in diversity only to the teleost family Cyprinidae. The Gobiidae consists of more than 200 genera and nearly 2,000 species and make up the largest family of marine fishes. Gobies account for as much as 50% of the energy flow in coral reef communities. Their small size, ability to adapt to numerous ecological

This book gathers current data on the two types of fish metamorphoses and their endocrine controls. It will be of interest for fish biologists as well as comparative physiologists and endocrinologists. Metamorphosis is a major developmental phase characterized by morphological and physiological changes. It prepares organisms for a drastic shift in

Butterflyfishes (family Chaetodontidae) are a highly conspicuous component of fish fauna on coral reefs throughout the world. In light of their strong dependence on coral, they are often regarded as the epitome of coral reef fishes. This volume examines the ecology and conservation of coral reef butterflyfishes. It provides important insights on their evolution and key events and adaptations that have led to their proliferation within coral reef ecosystems. Key to the longevity of butterflyfishes is the evolution of coral-feeding—a central focus of the ecological chapters in this volume. The book also highlights key threats and challenges related to the conservation of butterflyfishes and ends with an overview of current and future research directions.

During the past two decades, fish endocrinology has witnessed exciting developments due to our increased knowledge at all levels of biological organizations, including molecular biology, cell biology, physiology and behavior. New insights into development, neurobiology, immunology and molecular genetics closely correlated with classical aspects of endocrinology and represent important contributions to our knowledge on regulatory processes of vertebrates, including fish. The purpose of this book is to overview major advances in numerous research areas of fish endocrinology. Most of the chapters not only review and discuss the state-of-the-art in the respective field, but also show perspectives of future research. The book will be of interest to scientists involved in basic fish research, comparative endocrinology, fisheries and aquaculture as well as for students of fish biology.

Among all vertebrates, gobies are second in diversity only to the teleost family Cyprinidae. The Gobiidae consists of more than 200 genera and nearly 2,000 species and make up the largest family of marine fishes. Gobies account for as much as 50% of the energy flow in coral reef communities. Their small size, ability to adapt to numerous ecological niches and to be bred in aquaria has led to numerous studies both in the field and laboratory. Gobies are found from above the high tide line to depths of over 1,100 m. Some species are found only within caves, others deep inside sponges, and some others climb waterfalls to return to their native streams. They vary reproductively from gonochoric to hermaphrodite, monogamy to polygyny and promiscuity, some have short life spans and reproduce only once while others have longer life spans reproducing one or more times per year. The Biology of Gobies written by over 30 experts from 15 countries summarizes what is known about the systematics, ecology, zoogeography, and general biology of the Gobiiformes. This foundation will provide the basic information necessary for future studies.

This book gathers current data on the two types of fish metamorphoses and their endocrine controls. It will be of interest for fish biologists as well as comparative physiologists and endocrinologists. Metamorphosis is a major developmental phase characterized by morphological and physiological changes. It prepares organisms for a drastic shift in habitat and behavior. Among vertebrates, besides the well-known larval metamorphosis in amphibians, two types of metamorphosis are also described in the life cycle of some fish species. Larval metamorphosis, also called first metamorphosis or true metamorphosis, is encountered in lampreys, representative species of basal vertebrates as well as in some teleost groups, elopomorphs and pleuronectiforms, and possibly also in some other teleost species. Secondary metamorphosis occurs in juveniles of some diadromic migratory teleosts, such as salmons and eels, and compared to larval metamorphosis, involves less drastic morphological changes.

This two-volume set deals with diverse information on fossil and modern siluriform fishes, providing an overview of knowledge, research and scientific disagreements yet to be solved. The book is a synethesis of specialized articles that present the state of knowledge of catfish biology. The first volume covers anatomy, function and functional morphology, and the phylogenetic relationships among siluriforms and systematics of certain catfish groups. The second volume includes chapters on the fossil records and palaeodistribution, ecology and ethology, development and sensory biology.
