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.

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.

Game fishes, particularly those of the salmon family, are critical indicators of the health of those ecosystems upon which we now know we are dependent. As the authors of this important environmental book argue, "Our game fishes [then] serve as more than merely an indicator of healthy waters. Instead, they can be regarded as iconic of the ecosystems in which they occur." Moreover, "the quality requirements of different types of fish population have formed the backbone of a great deal of water management in the UK, Europe and the USA over several decades." With sections on how and why Britain's game fishes are under pressure from changes in land use, agriculture, housing needs, etc. - and their concomitant pollution effects - this book assesses how our knowledge of these game fishes reflect the changing values we place on our surrounding wildlife.

Fishes have evolved to colonise almost every type of aquatic habitat and today they are a hugely diverse group of over 25,000 species. The evolution of this great diversity of species has resulted in a myriad of solutions to the demands posed by the aquatic environment. Ecological and Environmental Physiology of Fishes presents a current and comprehensive overview of fish physiology to demonstrate how living fishes function in their environment. As with other books in the Series, the emphasis is on the unique physiological characteristics of the fish, but with applications to questions of broad relevance in physiological ecology. A preliminary chapter introduces the aquatic environment and gives a general description of fish biology, evolution, and taxonomy. Subsequent sections discuss the particular problems of living in water, life in extreme environments, techniques for studying fish ecophysiology, and future research directions.

Freshwater fish are one of the most diverse groups of vertebrates, but are also amongst the most threatened. With contributions from leaders in the field, this is the first assessment of the global state of freshwater fish diversity, synthesising the opportunities, challenges and barriers facing the conservation of freshwater fish biodiversity. The book includes the first global assessment of the number, type and distribution of threatened freshwater fish species, discussing the features of freshwater fish biology and ecology that render so many species vulnerable to extinction. Introductory chapters on why freshwater fish are so sensitive to environmental change and disturbance lead into chapters providing detailed reviews of the key threatening processes and potential solutions. A concluding chapter summarises the key issues and looks to the future for opportunities and challenges for the conservation and management of freshwater fish.

With over 7,000 known species, frogs display a stunning array of forms and behaviors. A single gram of the toxin produced by the skin of the Golden Poison Frog can kill 100,000 people. Male Darwin's Frogs carry their tadpoles in their vocal sacs for sixty days before coughing them out into the world. The Wood Frogs of North America freeze every winter, reanimating in the spring from the glucose and urea that prevent cell collapse. The Book of Frogs commemorates the diversity and magnificence of all of these creatures, and many more. Six hundred of nature's most fascinating frog species are displayed, with each entry including a distribution map, sketches of the frogs, species identification, natural history, and conservation status. Life-size color photos show the frogs at their actual size--including the colossal seven-pound Goliath Frog. Accessibly written by expert Tim Halliday and containing the most up-to-date information, The Book of Frogs will captivate both veteran researchers and amateur herpetologists. As frogs increasingly make headlines for their troubling worldwide decline, the importance of these fascinating creatures to their ecosystems remains underappreciated. The Book of Frogs brings readers face to face with six hundred astonishingly unique and irreplaceable species that display a diverse array of adaptations to habitats that are under threat of destruction throughout the world.

An insightful exploration of the iconic Galapagos tortoises, and how their fate is inextricably linked to our own in a rapidly changing world The Galapagos archipelago is often viewed as a last foothold of pristine nature. For sixty years, conservationists have worked to restore this evolutionary Eden after centuries of exploitation at the hands of pirates, whalers, and island settlers. This book tells the story of the islands' namesakes-the giant tortoises-as coveted food sources, objects of natural history, and famous icons of conservation and tourism. By doing so, it brings into stark relief the paradoxical, and impossible, goal of conserving species by trying to restore a past state of prehistoric evolution. The tortoises, Elizabeth Hennessy demonstrates, are not prehistoric, but rather microcosms whose stories show how deeply human and nonhuman life are entangled. In a world where evolution is thoroughly shaped by global history, Hennessy puts forward a vision for conservation based on reckoning with the past, rather than trying to erase it.

The zebrafish has become one of the most important model organisms to study biological processes within a living body. As a vertebrate that has many of the strengths of invertebrate model systems, it offers numerous advantages to researchers interested in many aspects of embryonic development, physiology and disease. This book not only provides a complete set of instructions that will allow researchers to establish the zebrafish in their laboratory. It also gives a broad overview of commonly used methods and a comprehensive collection of protocols describing the most powerful techniques.

First published in 1996, this new edition of ""Shore Fishes of Hawai'i"" updates our knowledge of Hawaiian fishes and has been expanded to include 372 species. All are illustrated by the author's 475 superb color photographs. The most important characteristics to identify a fish are given as well as the size attained and its distribution. Each species account begins with the American common name, followed by the Hawaiian name (when known), and the scientific name. Because it is necessary to use some scientific terminology when giving the principal diagnostic characteristics of families or species of fishes and what they eat, a handy glossary appears at the back of the book.

Fish are one of the most important global food sources, supplying a significant share of the world's protein consumption. From stocks of wild Alaskan salmon and North Sea cod to entire fish communities with myriad species, fisheries require careful management to ensure that stocks remain productive, and mathematical models are essential tools for doing so. Fish Ecology, Evolution, and Exploitation is an authoritative introduction to the modern size- and trait-based approach to fish populations and communities. Ken Andersen covers the theoretical foundations, mathematical formulations, and real-world applications of this powerful new modeling method, which is grounded in the latest ecological theory and population biology. He begins with fundamental assumptions on the level of individuals and goes on to cover population demography and fisheries impact assessments. He shows how size- and trait-based models shed new light on familiar fisheries concepts such as maximum sustainable yield and fisheries selectivity-insights that classic age-based theory can't provide-and develops novel evolutionary impacts of fishing. Andersen extends the theory to entire fish communities and uses it to support the ecosystem approach to fisheries management, and forges critical links between trait-based methods and evolutionary ecology. Accessible to ecologists with a basic quantitative background, this incisive book unifies the thinking in ecology and fisheries science and is an indispensable reference for anyone seeking to apply size- and trait-based models to fish demography, fisheries impact assessments, and fish evolutionary ecology.

The Amazon Basin's rivers, estuaries and tributaries are home to as many as 1000 species of catfish. In this work, two scientists offer a natural history of the Amazon giant catfish and its central place as a source of food and income within the ecology and economy of the Amazon Basin. While focusing primarily on two species of giant catfish - known locally as Dourada and Piramutaba - the authors also present illustrated accounts of 13 distinct large fish. Their research yields strong statistical data and field observations that illustrate the catfishes' extensive migratory range and presents solid evidence of animal species requiring or using a large part of the basin for their ecological needs. This text also proposes techniques for the careful management of this resource to ensure its survival for future generations. This study should be a useful reference for marine and conservation biologists in the field, ecologists, resource management professionals and development workers.

The North American freshwater fish fauna is the most diverse and thoroughly researched temperate fish fauna in the world. "Ecology of North American Freshwater Fishes" is the only textbook to provide advanced undergraduate and graduate students and researchers with an up-to-date and integrated view of the ecological and evolutionary concepts, principles, and processes involved in the formation and maintenance of this fauna. "Ecology of North American Freshwater Fishes" provides readers with a broad understanding of why specific species and assemblages occur in particular places. Additionally, the text explores how individuals and species interact with each other and with their environments, how such interactions have been altered by anthropogenic impacts, and the relative success of efforts to restore damaged ecosystems. This book is designed for use in courses related to aquatic and fish ecology, fish biology, ichthyology, and related advanced ecology and conservation courses, and is divided into five sections for ease of use. Chapter summaries, supplemental reading lists, online sources, extensive figures, and color photography are included to guide readers through the material and facilitate student learning. Part 1: Faunal origins, evolution, and diversity Presents a broad picture - both spatially and temporally - of the derivation of the fauna, including global and regional geological and climatological processes and their effects on North American fishes. Part 2: Formation, maintenance, and persistence of local populations and assemblages. Focuses on how local fish populations and assemblages are formed and how they persist, or not, through time. Part 3: Form and function Deals with the relationship of body form and life history patterns as they are related to ecological functions. Part 4: Interactions among individuals and species Discusses the numerous interactions among individuals and species through communication, competition, predation, mutualism, and facilitation. Part 5: Issues in conservation. Focuses on several primary conservation issues such as flow alterations and the increasing biotic homogenization of faunas.

This book reviews up-to-date knowledge on the biology of sole (Solea senegalensis and S. solea). These flatfish species are increasingly important in Europe both from the ecological and production point of view. This book is divided into two sections: A. general fisheries, aquaculture and engineering overviews; B. physiological, developmental, rhythmic, welfare and genetic aspects which will be of immense interest for the aquaculture industry. Experts, from both academia and research institutes, provide their expertise on sole biology.

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.

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.
