Fish lives in environments with a wide variety of chemical characteristics (fresh, brackish and seawater, acidic, alkaline, soft and hard waters). From an osmoregulatory point of view, fish have developed several mechanisms to live in these different environments. Fish osmoregulation has always attracted considerable attention and in the last years several studies have increased our knowledge of this physiological process. In this book several specialists have analyzed and reviewed the new data published regarding fish osmoregulation. The chapters present an integrative synthesis of the different aspects of this field focusing on osmoregulation in specific environments or situations, function of osmoregulatory organs, general mechanisms and endocrine control. In addition, interactions of osmoregulatory mechanisms with the immune system, diet and metabolism were also reviewed. New emerging techniques to study osmoregulation has also been analysed.

Knowledge of the early life stages of fishes is crucial for the effective monitoring and management of fish populations and habitats, and the evaluation of environmental impacts and recovery of endangered species. Unfortunately, the proper identification of targeted species has stunted the development of the field. Now a series has emerged that stands as the leading resource on the reproduction and development of many North American fishes. Reproductive Biology and Early Life History of Fishes in the Ohio River Drainage fills immense gaps in knowledge of issues related to early life development of fishes in the Ohio Basin. Volume 4 addresses the developmental and morphological issues of Perch, Pikeperch, and Darters. This volume describes the characteristics of the family Percidae, and provides a detailed pictorial guide to the young of all fish families present in the Ohio River drainage. Subtopics within each species description include range, distribution, occurrence, spawning, eggs, development, ecology of early life phases, and more. This book serves as both a handbook to help identify individual larval fish, and as a reference for those concerned with the overall health of the ecosystems or fisheries that they are monitoring.

CHOICE 'Highly Recommended for all readers' June 2021 Vol. 58 No. 10 This stunningly illustrated book goes far beyond a run-of-the-mill nature guide. It explores the fascinating life histories of Britain's freshwater fishes, a group of animals which, despite their importance and ubiquity in our diverse still and flowing fresh waters, has before now been rarely regarded and respected as 'wildlife'. Our native fishes tend generally to be considered as simply something for anglers to catch or for people to eat, yet they work enormously hard for us. Author Mark Everard, avid nature-watcher, angler and scientist, shows how freshwater fish provide food, ornamentation, sport and cultural identity, and highlights their huge importance for conservation as part of the living ecosystems upon which we all depend. He dives into the mysteries moving below the surface of our rivers and lakes, bringing the wonderful and fascinating world of the diversity of British freshwater fish species into plain sight and into mind. This unique book features over 100 full-colour photographs by pioneering photographer and filmmaker Jack Perks, whose work has featured on BBC Springwatch, The One Show and Countryfile. The book is filled with technical detail useful to conservationists and biology students. Most importantly, it is also presented in an accessible, visually attractive and engaging manner that will appeal to anybody with an interest in the natural world: the conservation-minded public, the angling community, and our nation of wildlife enthusiasts. Whatever your background, this book will open your eyes to our freshwater fishy wealth, and the many ways in which it enriches our lives.

Reviews: Methods and Technology in Fish Biology and Fisheries published by Kluwer Academic Publishers is a book series dedicated to the publication of information on advanced, forward-looking methodologies, technologies, or perspectives in fish and fisheries. This series is especially dedicated to relevant topics addressing global, international concern in fish and fisheries. Humans continue to challenge our environments with new technologies and technological applications. The dynamic creativity of our own species often tends to place the greatest burden on our supporting ecosystems. This is especially true for aquatic networks of creeks, lakes, rivers and ocean environments. We also frequently use our conceptual powers to balance conflicting requirements and demands on nature and continue to develop new approaches and tools to provide sustainable resources as well as conserve what we hold most dear on local and global scales. This book series will provide a window into the developing dynamic among humans, aquatic ecosystems (both freshwater and marine), and the organisms that inhabit aquatic environments. There are many reasons to doubt the increasing social and economic value technology has gained over the last two centuries. Science and technology represent stages in human development. I agree with Ernst Mayer when he said in Toward a New Philosophy of Biology (1988) that "endeavors to solve all scientific problems by pure logic and refined measurements are unproductive, if not totally irrelevant.

Agile, sleek, and precise, sharks display many qualities we can admire and appreciate. These marvels of evolution have adapted to thrive in every major aquatic realm on the planet, from frigid Arctic waters through temperate but stormy seas and on into the tropics. However, few places on Earth are home to the amazing diversity of shark species that beautify the shallow waters of Florida and the Bahamas. In this first-ever book dedicated to the sharks of this region, biologist Jeffrey C. Carrier reveals the captivating lives of these large marine predators and describes how they have survived for over 400 million years. Guiding readers through basic biology, key attributes, and identification tips, the book explores what makes sharks such successful apex predators. Carrier explains fascinating phenomena, including the reason for the bizarre shape of the hammerhead, how a bull shark is able to swim hundreds of miles up freshwater rivers, what lies behind sharks' remarkable capability to learn and remember, and why many scientists believe that they are equipped with the most sophisticated sensory systems in the animal kingdom. With the stunning full-color underwater photography of Andy Murch, Jillian Morris, and Duncan Brake, Sharks of the Shallows brings boaters, fishers, divers, and shark lovers directly alongside these unfairly maligned creatures. And not a moment too soon! Sharks are experiencing stresses unlike any in their long history, and are struggling to survive in a changing ocean. They will continue to grace our coastlines only if we care enough to understand them.

The Reef Guide documents some 800 reef fishes and invertebrates found along the east and south coasts of southern Africa.

Following on the success of Dennis King’s earlier two titles, this impressive new guide features 578 species of fish and includes sections on anemones, starfish, snails, crabs and shrimps.

Full-colour photographs and descriptive text for each species, along with useful and interesting information, make for easy identification. While focusing on southern Africa, the book is also applicable to the entire east coast of Africa, as well as the islands of the western Indian Ocean – Seychelles, Mauritius, Reunion, Madagascar, the Comoros and the Maldives.

Indispensable for divers, snorkelers and rock-pool enthusiasts, as well as fishermen and marine aquarists.

Ecologists have long struggled to understand community dynamics. In this groundbreaking book, leading fish ecologists William Matthews and Edie Marsh-Matthews apply long-term studies of stream fish communities to several enduring questions. This critical synthesis reaches to the heart of ecological theory, testing concepts against the four decades of data the authors have collected from numerous warm-water stream fish communities in the central and eastern United States. Stream Fish Community Dynamics draws together the work of a single research team to provide fresh analyses of the short- and long-term dynamics of numerous streams, each with multiple sampling sites. Conducting repeated surveys of fish communities at temporal scales from months to decades, the authors' research findings will fascinate anyone searching for a deeper understanding of community ecology. The study sites covered by this book range from small headwater creeks to large prairie rivers in Oklahoma and from Ozark and Ouachita mountain streams in Arkansas to the upland Roanoke River in Virginia. The book includes* A comparison of all global and local communities with respect to community composition at the species and family level, emergent community properties, and the relationship between those emergent properties and the environments of the study sites* Analyses of traits of individual species that are important to their distribution or success in harsh environments* A review of evidence for the importance of interactions-including competition and predation-in community dynamics of stream fishes* An assessment of disturbance effects in fish community dynamics* New analysis of the short- and long-term dynamics of variation in stream fish communities, illustrating the applicability and importance of the "loose equilibrium concept"* New analyses and comparisons of spatiotemporal variation in community dynamics and beta diversity partitioning* An overview of the effects of fish in ecosystems in the central and eastern United States The book ends with a summary chapter that places the authors' findings in broader contexts and describes how the "loose equilibrium concept"-which may be the most appropriate default assumption for dynamics of stream fishes in the changing climate of the future-applies to many kinds of stream fish communities.

Fish are a unique group which harbour some 30,000 species of helminths that do not occur in other vertebrates. This book deals specifically with parasitic worms of fish. It covers every aspect of their biology including identification, life-cycles, hostparasite relationships and ecology. It discusses approaches to studying parasitic worm infections, preference of species for particular host species, preference for dwelling in certain organs and tissues, biogeography, seasonality of infections and how parasites have evolved in parallel with their hosts. The book concludes with discussions of fish worms causing diseases in nature and in fish-farms. This section also addresses the value of parasitic worms in extending knowledge of the environments in which fish and their parasites dwell, from the use of worms as indicators of pollution or for determining the location, migrations, and feeding behavior of fish stocks. With the growth in fish farming such parasites have considerable economic as well as scientific significance.; This volume provides an account of these helminths and reviews how studies on fish worms have increased current knowledge of worm biology in general.; The bibliography contains over 3500 references and an appendix summarizes important information on biochemistry and physiology of fish worms.

Fish Pathology is the definitive, classic and essential book on the subject, providing in-depth coverage across all major aspects of fish pathology. This new, fully updated and expanded fourth edition builds upon the success of the previous editions which have made Fish Pathology the best known and most respected book in the field, worldwide.Commencing with a chapter covering the aquatic environment, the book provides comprehensive details of the anatomy and physiology of teleosts, pathophysiology and sytematic physiology, immunology, neoplasia, virology, parasitology, bacteriology, mycology, nutritional pathology and other non-infectious diseases. A final chapter provides extremely useful details of the most widely-used and trusted laboratory methods in the area. Much new infomation is included in this new edition, including enhanced coverage of any diseases which have become commercially significant since publication of the previous edition Beautifully illustrated in full colour throughout with many exceptional photographs, Fish Pathology, Fourth Edition, is an essential purchase for fish pathologists, fish veterinarians, biologists, microbiologists and immunologists, including all those working in diagnostic services worldwide. Personnel working in fish farming and fisheries will also find much of great use and interest within the book's covers. All libraries in universities and research establishments where biological and veterinary sciences are studied and taught should have copies of this landmark publication on their shelves.

Metamorphosis and the transition from larvae or embryos to juveniles in fishes are important in order to answer, for example, questions about: (1) life-history styles and their modifications in evolutionary perspective and within current environmental demands; (2) the development and application of fisheries recruitment models, (3) the use of ontogenetic scales for interspecific comparisons, (4) the identification of ontogenetic shifts in resource use, and (5) the discovery of evolutionary interrelationships of species or genera. This volume is dedicated to recent studies and reviews of existing knowledge on this insufficiently-addressed area of ichthyology. Most of the papers in this volume were presented in Bratislava, Slovakia, at the 1st International Workshop of the Fish Ontogeny Network of Europe (FONE) in September 1997, a meeting sponsored in part by the European Commission. This volume emphasizes an integrated approach to the study of fish ontogeny, which is a process during which one event is related to another and everything is related to everything else, encompassing physiology, morphology, behaviour and niche. Within this comprehensive perspective, the papers in this volume are grouped along four major themes: reflections on early ontogeny and metamorphosis, organism-environment relationships, ontogeny of predator-prey interactions, and behaviour and ontogeny. Among other issues, the papers consider topics such as whether one can identify when fish metamorphosis ends, whether the larva period begins with hatching or with the onset of exogenous feeding, whether fish ontogeny is `saltatory' or `gradual', and whether larvae are eliminated in some fishes with direct development. The keynote paper of this volume reviews the main topics within contemporary paradigms and the final paper concludes that the onset of the juvenile period can be identified in some species, but precision remains problematic, emphasizing the need for further research in this dynamic area of fish biology.

Fish is the principal source of protein for people in many parts of the world, particularly in developing countries. While most fish are caught from nature, aquaculture or fish farming is now making a significant contribution to total fish production. More intensive conditions of aquaculture often result in a higher incidence of fish diseases and disorders. As in the first edition, the focus of this second edition is on protozoan and metazoan parasites that cause disease in fish. Significant changes to this second edition include the addition of three new chapters and four of the original chapters have new authors.

Using R for Modelling and Quantitative Methods in Fisheries has evolved and been adapted from an earlier book by the same author and provides a detailed introduction to analytical methods commonly used by fishery scientists, ecologists, and advanced students using the open-source software R as a programming tool. Some knowledge of R is assumed, as this is a book about using R, but an introduction to the development and working of functions, and how one can explore the contents of R functions and packages, is provided. The example analyses proceed step-by-step using code listed in the book and from the book's companion R package, MQMF, available from GitHub and the standard archive, CRAN. The examples are designed to be simple to modify so the reader can quickly adapt the methods described to use with their own data. A primary aim of the book is to be a useful resource to natural resource practitioners and students. Featured Chapters: Model Parameter Estimation provides a detailed explanation of the requirements and steps involved in fitting models to data, using R and, mainly, maximum likelihood methods. On Uncertainty uses R to implement bootstrapping, likelihood profiles, asymptotic errors, and Bayesian posteriors to characterize any uncertainty in an analysis. The use of the Monte Carlo Markov Chain methodology is examined in some detail. Surplus Production Models applies all the methods examined in the earlier parts of the book to conducting a stock assessment. This included fitting alternative models to the available data, characterizing the uncertainty in different ways, and projecting the optimum models forward in time as the basis for providing useful management advice.

The Eponym Dictionary is a series of brief but concise biographies of all those people after whom fish have been named in both the vernacular and scientific names. It also covers names which seem to be eponyms but are not, such as toponyms, names of organisations, ethnic groups, etc. It also shows the networks of scientific collaboration, friendship or patronage. Each species named after an individual is listed with their authors and years for context and wherever possible it is shown how the authors and the eponym are linked. Every effort has been made to be accurate and meticulous, and the book is also a repository of biographical knowledge that will entertain as well as inform. In conjunction with the other books it forms a database of everyone named in a vertebrate. For ease of use, this volume is designed as a dictionary, making it easy to find the person behind the name and, in doing so, discover which fish commemorates them and learn something of their lives and background. For many obscure individuals, these vignettes may be as full a biography of the person as possible, but for the famous it is merely a starting point that shows the enquirer, with confidence, the right person. Some brief entries summarise whole volumes of biography, especially those honoured in a name because of their standing in society rather than their scientific behaviour. There is a vast range of derivations related not just to scientists, zoologists and scholars, but also pop stars, TV and film personalities and writers. There is a whole world of aquarists and fish hobbyists, many of whom have been immortalised for adding to our knowledge of tropical fish. Moreover, there are many people whose only claim to fame is that naming. The parents, spouses, sons and daughters of ichthyologists are well-represented, as are their teachers and even their lovers. The Eponym Dictionary of Fishes is a web of relationships and connections, icons and idols.

This book gives a start-to-finish overview of the whole Fish4Knowledge project, in 18 short chapters, each describing one aspect of the project. The Fish4Knowledge project explored the possibilities of big video data, in this case from undersea video. Recording and analyzing 90 thousand hours of video from ten camera locations, the project gives a 3 year view of fish abundance in several tropical coral reefs off the coast of Taiwan. The research system built a remote recording network, over 100 Tb of storage, supercomputer processing, video target detection and tracking, fish species recognition and analysis, a large SQL database to record the results and an efficient retrieval mechanism. Novel user interface mechanisms were developed to provide easy access for marine ecologists, who wanted to explore the dataset. The book is a useful resource for system builders, as it gives an overview of the many new methods that were created to build the Fish4Knowledge system in a manner that also allows readers to see how all the components fit together.

Eel of the genus Anguilla is an extraordinary fish, which due to its particular life cycle has fascinated biologists and physiologists ever since the pioneering works of Homer H. Schmidt in the 1930s. The Eel has become an excellent model for various aspects of adaptive physiological research. Despite that, several books dealing with eel biology, aquaculture, fishing, etc., have been published, but there still is a need for a text dealing with eel physiology. This book fills a void in eel literature by presenting various aspects of eel physiology in one comprehensive volume. With its numerous figures and tables and an extensive up-to-date bibliography, it will be of interest not only to researchers and students but also to people engaged in applied research in fishery and aquaculture. Eel is a commercially important fish, but it must be protected from over-exploitation; as such, conservation measures are necessary. It is hoped that this book will stimulate and suggest new lines of research.

The first book to highlight research done by women of color in the field of shark science. A special emphasis is placed on amplifying the voices of Black, Indigenous, People of Color as well as artisanal fishers and economically disadvantaged coastal communities. Accessible to younger readers too, encouraging school children to get into marine science. Covers a broad range of topics including biology, ecology and evolution as well as some less talked about topics like outreach and stakeholder engagement. Interdisciplinary approach to shark science and conservation Easily digestible content for non-experts Focuses on a charismatic group of animals, sharks Offers diverse perspectives and cutting-edge research while diving into issues regarding the decolonization of shark science and changing public perception of sharks. This is an opportunity to challenge the notion that there is only one type of scientist or that scientists look and think a certain way.

This book summarizes the key adaptations enabling extremophile fishes to survive under harsh environmental conditions. It reviews the most recent research on acidic, Antarctic, cave, desert, hypersaline, hypoxic, temporary, and fast-flowing habitats, as well as naturally and anthropogenically toxic waters, while pointing out generalities that are evident across different study systems. Knowledge of the different adaptations that allow fish to cope with stressful environmental conditions furthers our understanding of basic physiological, ecological, and evolutionary principles. In several cases, evidence is provided for how the adaptation to extreme environments promotes the emergence of new species. Furthermore, a link is made to conservation biology, and how human activities have exacerbated existing extreme environments and created new ones. The book concludes with a discussion of major open questions in our understanding of the ecology and evolution of life in extreme environments.

Immunity studies in sharks over the past three decades have produced some remarkable discoveries. If one message rings true, it is that alternative animal model systems, such as sharks and their relatives, have contributed very substantially to a better understanding of the development evolution of our own immune system. Immunobiology of the Shark describes the cellular, genetic, and molecular specifics of immune systems in sharks. Diverse approaches were employed to study the immunobiology of the shark from basic microscopic observations to detailed genome annotation. The book also raises a series of fascinating questions, which can be addressed experimentally using today's technology. This book will be a valuable resource for mainstream immunologists, comparative immunologists, geneticists, ecologists, evolutionary biologists, and investigators engaged in shark research. The book also aims to illustrate the magnificence of these animals as model systems and underscores the importance of their study to further understand their complex, and often enigmatic, biology.

As the largest group of extant vertebrates, fish offer an almost limitless number of striking examples of evolutionary adaptation to environmental and biotic selection pressure. The most diverse of all vertebrate groups, the higher taxa of fish traditionally have been classified by morphology and paleontology, with a much smaller input of cytogenetic information. DNA sequence data are exerting an increasingly strong influence on modern fish systematics, challenging the classification of numerous higher taxa ranging from genera to orders. The most fruitful approach, however, involves synthetic analyses of morphology, molecular phylogenetics, comparative karyology, and genome size. Karyotypes of more than 3400 species/subspecies are arranged here by fish systematics and include a list of genome size, sex chromosomes, B chromosomes, polyploidy, and locality of material fish, among others. This volume enables both beginners and advanced researchers to survey the existing literature and facilitates the implementation of an integrative approach to fish systematics. The first book on fish chromosomes in nearly 15 years, it is also the most comprehensive.

Oryzias latipes, known as medaka, is a model organism from East Asia. Breeding of this small, egg-laying freshwater teleost fish has long been popular among hobbyists in Japan. Now, as biological science has entered the genome era, the medaka provides significant advantages that make it one of the most valuable vertebrate models: a large collection of spontaneous mutants collected over a century, the presence of highly polymorphic inbred lines established over decades, and a recently completed genome sequence. This book is the first comprehensive monograph to cover a variety of medaka research. It opens with a historical view of medaka, followed by a series of research topics in the four major areas where the medaka is increasingly important: genomics, genetics, and resources; organogenesis and disease models; germ cells, sex determination, and reproduction; and evolution. Readers will find state-of-the-art information on medaka genetics and genomics such as the first isolation of active transposons in vertebrates, the influence of chromatin structure on sequence variation, fine QTL analysis, and versatile mutants as human disease models.
