"This is a coursebook and reference guide for ichthyology courses that will also serve as a tool for ichthyologists, fisheries scientists, marine biologists, and vertebrate zoologists. It will cover the basic anatomy and diversity of all 62 orders of fishes, focusing on the distinguishing characteristics of approximately 180 of the most commonly encountered fish families. Each family will be diagnosed with easily observed characteristics and clear photos--many in color and from living specimens. This guide will be distinctive through the use of photographs of preserved specimens primarily from the Scripps Institution of Oceanography Marine Vertebrate Collection, supplemented by radiographs and additional illustrations of key characters. The goal is to give ichthyology students, fisheries scientists, marine biologists, vertebrate zoologists, and others with an interest or stake in the diversity of fishes a broad overview of the morphological diversity of fishes, arranged in a modern classification system. For students, it's a natural complement to primary ichthyology textbooks, which don't cover the breadth of morphological characteristics necessary to identify fish"--Provided by publisher.
Marine fishes have been intensively studied, and some of the fundamental ideas in the science of marine ecology have emerged from the body of knowledge derived from this diverse group of organisms. This unique, authoritative, and accessible reference, compiled by 35 luminary ecologists, evolutionary biologists, and ichthyologists, provides a synthesis and interpretation of the large, often daunting, body of information on the ecology of marine fishes. The focus is on the fauna of the eastern Pacific, especially the fishes of the California coast, a group among the most diverse and best studied of all marine ecosystems. A generously illustrated and comprehensive source of information, this volume will also be an important launching pad for future research and will shed new light on the study of marine fish ecology worldwide. The contributors touch on many fields in biology, including physiology, development, genetics, behavior, ecology, and evolution. The book includes sections on the history of research, both published and unpublished data, sections on collecting techniques, and references to important earlier studies.
Fishes form the largest group of vertebrates, with around 20,000 known species, and they display a remarkable diversity of size, shape, internal structure and ecology to cope with environments ranging from transient puddles to the abyssal depths of the sea. Life in water leads to particular problems for body fluid regulation, locomotion and sensory systems, and these have been resolved in the most ingenious ways. This book, the first edition of which was published in 1982, has been largely rewritten to take account of recent information resulting from the huge rate of publication of scientific papers and books on fishes. With the addition of J.H.S. Blaxter, the expertise of the original authors has been further widened, leading to new chapters on behaviour and on fisheries and aquaculture. A chapter on endocrines has also been added and all other chapters have been brought entirely up-to-date. The second edition includes a large number of new illustrations.
Written as a stand-alone textbook for students and a useful reference for professionals in government and private agencies, academic institutions, and consultants, Ecology and Conservation of Fishes provides broad, comprehensive, and systematic coverage of all aquatic systems from the mountains to the oceans. The book begins with overview discussions on the ecology, evolution, and diversity of fishes. It moves on to address freshwater, estuarine, and marine ecosystems and identifies factors that affect the distribution and abundance of fishes. It then examines the adaptations of fishes as a response to constraints posed in ecosystems. The book concludes with four chapters on applied ecology to discuss the critical issues of management, conservation, biodiversity crises, and climate change. Major marine fisheries have collapsed, and there are worldwide declines in freshwater fish populations. Fishery scientists and managers must become more effective at understanding and dealing with resource issues. If not, fish species, communities, and entire ecosystems will continue to decline as habitats change and species are lost. Ecology and Conservation of Fishes has taken a historical and functional approach to explain how we got where we are, providing old and new with a better foundation as ecologists and conservationists, and most importantly, it awakens senses of purpose and need. Past management practices are reviewed, present programs considered, and the need for incorporating principles of applied ecology in future practices is emphasized.
In recent years, progress in fish biology has advanced at an unprecedented rate and has led to many breakthroughs in the field. This book provides a wealth of information on the strategies that fish adopt with respect to waters with markedly different physical and chemical characteristics. It shows how their physiology, behaviour and lifestyles are adapted to exploit particular niches and gives comprehensive insight into fish life under extreme conditions. The readers are introduced to the ways in which fish exemplify many phenomena of general biological interest - the existence of competitors, chaos, and predator-prey interaction. Fish pathology as well as the components of the immune system are addressed. In this book, original and at times controversial views are presented, areas which have so far received inadequate attention are highlighted and avenues for further research are suggested.
With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.
