This book gives a concise account of the physiology and form of the fish circulatory system. The emphasis is primarily on function, but details of structure have been included. Following a revision of ideas on hemodynamics, attention is focused on the heart as the primary pump in the fish circulatory system. The fine structure and the electrical and ionic events of cardiac myocytes are described and the major events of the cardiac cycle are outlined. The structure of the peripheral vessels then follow and attention is devoted to the circulation in certain special areas such as the gills, the renal portal system, and the secondary blood system. There are also chapters devoted to the blood and the hemopoetic tissues and an account is given of the different types of retial systems that concentrate oxygen or heat in various parts of the body. Following a description of the autonomic nervous system, the circulatory responses to exercise and hypoxia are described. The book concludes with a discussion on the circulation of hagfish and how it illuminates our understanding of the functional and structural evolution of the circulatory system.

Since the industrialization of fishing, fisheries scientists have been subject to intense economic and political pressures, which have affected the way the science has developed. The origins and effects of these pressures are traced in this 1994 book to concerns about determining the causes of fluctuations in fish and whale catches, and to resistance to regulation of fishing activity when populations are depleted. The development of partial theories of fish population dynamics are described using examples of both national and international fisheries. The causes of the difficulties encountered in generalizing these theories are examined, setting the stage for the limitation of scope of these studies that still influences the form and extent of fisheries research today. This is a fascinating resource for all those interested in fisheries science and the way it has developed in the last 150 years.

In Darwin's Fishes, Daniel Pauly presents an encyclopaedia of ichthyology, ecology and evolution, based upon everything that Charles Darwin ever wrote about fish. Entries are arranged alphabetically and can be about, for example, a particular fish taxon, an anatomical part, a chemical substance, a scientist, a place, or an evolutionary or ecological concept. The reader can start wherever they like and are then led by a series of cross-references on a fascinating voyage of interconnected entries, each indirectly or directly connected with original writings from Darwin himself. Along the way, the reader is offered interpretation of the historical material put in the context of both Darwin's time and that of contemporary biology and ecology. This book is intended for anyone interested in fishes, the work of Charles Darwin, evolutionary biology and ecology, and natural history in general.

In order for biodiversity to be conserved, it is important to know how and where diverse assemblages of plants and animals exist, to understand the effects of human impacts on them, and to find the means by which these impacts can be lessened and even reversed. While tropical systems are known to be amongst the most diverse and most threatened globally, tropical freshwater systems have been neglected, and the tremendous variety of fish, amphibians, invertebrates and plants which live in them are poorly known yet seriously threatened. This comprehensive book brings together a wealth of information on the fish of tropical African systems, and discusses how these systems evolved, what holds them together, and what is tearing them apart. This is an important reference work not only for those interested in fish, but for all concerned with biodiversity conservation anywhere.

There is considerable global interest in the culture of finfish species both for cold and warm water aquaculture development and growth. Essential information on the biology, domestication and aquacultural characteristics of a wide selection of novel and established species is provided in the form of technical sheets, species descriptions and information on current rearing practices, making this a must-have reference in the field of aquacultural science. The book also offers a basic framework in order to support investment strategies for research and developement efforts aimed at the emergence of a profitable finfish aquaculture industry and presents a rationale for species diversification, different approaches to species selection and basic economical and market considerations governing the launch of strategic development and commercialization efforts.

This book celebrates the guppy's unique contribution to evolutionary ecology. Ever since Caryl Haskins described guppy populations as a 'natural experiment' because of the way predation pressure varies over a small geographical area, generations of researchers have been drawn to Trinidad to investigate evolution in the wild. The species continues to provide classic examples of natural selection in action and elegantly illustrates how ecology, evolution, and behaviour are interlinked.
Anne Magurran's account of the evolutionary ecology of the guppy integrates historical breakthroughs with new research in this fast-moving field. She reveals how guppies provided some of the first evidence of sperm competition and sexual selection, and how they continue to inform scientific thought on mating systems and cryptic choice. The consequences of variation in predation risk--as well as a host of other biotic and abiotic factors--are described and evaluated at all life stages from conception to death. The book discusses behavioural responses to ecological conditions alongside life history patterns. It examines the potential for ecological speciation and discusses new research into how reproductive isolating mechanisms become established in promiscuous mating systems. Conservation issues are also considered, both in terms of protecting the irreplaceable Trinidadian guppy system and in the context of invasion ecology.
This timely synthesis of research into a species that has raised key questions in evolutionary ecology will be of great interest to graduate level students as well as professional researchers in the fields of behavioural ecology and evolutionary biology.

Variation in salmonids can be used to illustrate virtually all evolution.

Global warming and climate change are growing environmental concerns which are much in the scientific, governmental and public eye. The potential impact on freshwater and marine fishes is immense, because most fish have no physiological ability to regulate their body temperature. This volume focuses on the effects of temperature at all levels of organization in fish, with particular emphasis on physiological function: cells, epithelia, organ systems, the whole organism, reproduction, behaviour, pollutant interactions, ecology and population dynamics, with each chapter written by experts in the field. Many chapters also speculate on the long-term physiological and ecological implications to fish of a 2-4 DegreesC global warming scenario. Researchers and graduate students in the areas of animal physiology and behaviour, environmental toxicology, population ecology and fisheries biology and management will find this volume of particular interest.

Provides a thorough introduction to the biology of fishes, covering basic diversity, biology and physiology. Detailed coverage of environmental aspects relating to fish biology is a key feature of this book which will be of great use to students and individuals in fish biology, fisheries, aquaculture and environmental sciences.

How do fish populations regulate themselves? Why do some fish stocks flourish and then die away? These questions have fascinated fisheries scientists for decades, and in the last twenty years answers have begun to emerge. In this comprehensive 1995 account, David Cushing shows how the fate of fish larvae which live close to the centres of production in the sea has a crucial effect on population regulation. He shows how the timing and development of tidal fronts in particular regions has profound implications for fish and plankton production, which in turn affects fish recruitment. If recruitment of fish larvae into the pool of adult fish is insufficient, stocks may fail. It is only by understanding these processes that we can hope to recognise the implications of global climate change on marine populations. This book will be essential reading for all those interested in marine ecology and fisheries biology.

The threespine stickleback is a small fish of temperate coastal and fresh waters that exhibits extraordinary phenotypic diversity. Benefiting from its amenability to observation in the field and manipulation in the laboratory, Niko Tinbergen pioneered the threespine stickleback's use in behavioral studies and established it as a model system in ethology. This up-to-date volume incorporates reviews from active researchers who use studies of the fish to address a broad variety of evolutionary issues, including optimal foraging, armor variation, speciation, and the endocrine basis for correlated behavioral characters. The work demonstrates the value of viewing the biology of a single organism simultaneously from multiple perspectives. Students and researchers in ecology, evolution, animal behavior, and vertebrate zoology will find much of interest in this useful book.

Michael Muller has carved a career out of impressive encounters. Famed for his portraits of the world's most elite actors, musicians, and sports stars, he has in the last decade built up one of the most spectacular portfolios of underwater shark photography. Muller's quest is to document sharks with an unprecedented proximity and precision, bringing the Hollywood portrait session to the ocean predator. In ocean depths around the world, he approaches the sharks with a patented seven-bulb, 1200-watt plexi-encased strobe lighting rig, developed with NASA engineering, and no cage. This collection of Muller's images, including the first-known photograph of a great white breaching at night, is a catalog of adrenalin and awe. Arranged geographically, it follows Muller's ocean adventures from black tip and sand tiger sharks in South Africa to great hammerheads in the Bahamas, with thrilling narratives from each trip documenting the challenges and near-misses along the way. To compliment Muller's work for advocacy organizations such as WildAid and EarthEcho, the images are contextualized with essays from Philippe Cousteau, Jr. and marine biologist Alison Kock, who discuss exploration and conservation of our oceanic kingdom. Culture writer Arty Nelson adds an overview of Muller's work, while a technical section explains the precise equipment behind these spectacular shots. Together, these insightful texts and awesome images offer a record of breathtaking photographic feats, a tribute to the beauty and might of the shark, and a rallying cry for its fragile future. This book is also available in a signed Collector's Edition and two Art Editions, each including a signed and numbered print.

Aquaculture exemplifies the ongoing global struggle to strike a sustainable balance between the conflicting needs of a rapidly increasing world population, human health, ecosystem health, the welfare of wild and domesticated animals, and the economic principles of globalized economies. On the one hand, aquaculture has great potential for providing us with a healthy and nutritious food supply whilst alleviating pressure on captive fisheries and reducing fisheries-induced habitat destruction, overfishing, genetic modification of wild populations, and wholesale waste of bycatch. On the other hand, aquaculture relies heavily on clean water, an increasingly precious (and dwindling) resource that is subject to intense pressure of being used for many competing objectives. This concise primer introduces students to the basic concepts, opportunities, and challenges of aquaculture with an emphasis on ecological considerations. It provides a critical assessment of current aquaculture practices from a broad, interdisciplinary perspective and from the standpoint of how best to align the two major (and often conflicting) goals of future aquaculture development: minimizing reliance on ecosystem services whilst maximizing productivity. A Primer of Ecological Aquaculture provides an accessible and authoritative overview for a wide range of undergraduate majors ranging from biology, engineering, and environmental policy to business and management. It will also appeal to a more general academic audience who wish to gain a current overview of the field.
