This book deals with chemosensory systems of fishes and covers the well known olfactory and the gustatory senses as well as the less popular solitary chemosensory cells. Chemosenses play an essential role in the life of a fish. They help fish in their search for food, to consume it and digest it. They also help fish to find their conspecifics and to avoid enemies or predators. Fish live in varied and often extreme ecological conditions frequently inhabiting niches such as caves or at great depths in the oceans. The chemosensory organs of such well adapted fish are highly specialized and evolved in contrast to the chemosenses of sight-hunting fish. Fishes have developed diverse strategies to survive within the widely varying water bodies, owing, at least in part, to the highly evolved chemosensory systems. A group of internationally reputed specialists have contributed to this book. It contains six chapters devoted to fish olfaction, one chapter to solitary chemosensory cells and six chapters to the fish taste

Half of the 12 papers are research reports selected from the presentations to an international conference at Manonmaniam Sundaranar University on an undisclosed date. The others are reviews of literature on the same theme of advanced technologies in fisheries and marine sciences. Among the topics are gene transfer to germline and somatic tissues of

Many different kinds of animals have adopted a parasitic life style on the skin and gills of marine and freshwater fishes, including protozoans, flatworms, leeches, a range of crustaceans and even some vertebrates (lampreys). There is a parasitic barnacle, described first in the 19th century by Charles Darwin, fish lice that change sex and bivalve molluscs parasitic only when young. This book explores for the first time in one volume, the remarkable biology of these little known and frequently bizarre animals.

The following closely interwoven themes are considered for each group of parasites: how they find their hosts, how they attach, feed and reproduce, the damage they inflict and how the hosta (TM)s immune system retaliates. Based on the British fauna, but extending where appropriate to examples from North America, Australia and elsewhere, the book is essential reading, not just for the professional parasitologist, but also for anyone interested in fishes and in this neglected field of British natural history.

With the enquiring naturalist in mind, terms and concepts are explained as they arise, backed up by a glossary, and the text is liberally illustrated. An introductory chapter on fish biology sets the scene and common fish names are used throughout, as well as scientific names.

Over the last decade, the study of shark biology has benefited from the development, refinement, and rapid expansion of novel techniques and advances in technology. These have given new insight into the fields of shark genetics, feeding, foraging, bioenergetics, imaging, age and growth, movement, migration, habitat preference, and habitat use. This pioneering book, written by experts in shark biology, examines technologies such as autonomous vehicle tracking, underwater video approaches, molecular genetics techniques, and accelerometry, among many others. Each detailed chapter offers new insights and promises for future studies of elasmobranch biology, provides an overview of appropriate uses of each technique, and can be readily extended to other aquatic fish and marine mammals and reptiles. Including chapter authors who were pioneers in developing some of the technologies discussed in the book, this book serves as the first single-source reference with in-depth coverage of techniques appropriate for the laboratory and field study of sharks, skates, and rays. It concludes with a unique section on Citizen Science and its application to studies of shark biology. This is a must-read for any marine biologist or scientist working in the field of shark biology, as well as marine biology students and graduates.

The spotted seatrout is an important species not only for recreational and commercial fisheries, but also as an integral part of many estuarine ecosystems. As one of the few fishes that live its entire life within an estuarine system, the species has tremendous potential as a monitor or sentinel for estuarine conditions. Prepared by the foremost authorities in their respective fields, Biology of the Spotted Seatrout presents an up-to-date summary of what is known about the basic biology of this important species.

This innovative reference provides current life history information on this species for the expressed purpose of beginning the task of assessing differences in estuarine restricted sub-populations of spotted seatrout. It serves as a model of a biological summary directed toward determining which of the life history parameters will most aptly serve as bioindicators to meet overall environmental management needs. It integrates estuarine specific life history features into the overall management of both estuaries and an estuarine dependent fishery.

Biology of the Spotted Seatrout includes a classic systematic approach to studying the relationships between seatrout genera as well as a more modern approach to investigating intra- and inter-estuarine differences in genetic structure. Ecologists, fisheries biologists and managers, and environmental scientists worldwide will be able to use the information presented in this book as a model on which to establish a database of information to be used to assess and compare estuarine conditions and environmental health. This valuable book serves as a blueprint for bringing together the biological criteria necessary to begin landscape scale comparisons of estuaries based on the biological information of totally estuarine dependent species, such as the spotted seatrout.

Fish constitute an important natural renewable resource and any reduction in their ability to propagate as a result of human interference may have significant socioeconomic consequences. The negative effect of human activity on sex differentiation and reproductive output in fish is so diverse that it has been difficult to encompass it in a single book. This book serves as the first attempt to do so. Unlike in mammals, the expression of a host of sex differentiation genes in fish is mostly controlled by environmental factors. Not surprisingly, environmental sex differentiation is ubiquitous in fish. Overexploitation by capture fisheries does not disrupt sex differentiation but crowding in aqua-farms does, by reducing accessibility to food supply. Some of the man-made chemicals routinely used worldwide mimic endogenous hormones. For example endosulfan, which is widely used in developing countries, disrupts endogenous hormones and feminizes fish. For the first time, this book views endocrine disruption from the point of labile early life and non-labile adult stages. It shows that sex can irreversibly be reversed, when exposed to endocrine disrupting chemicals (EDCs) during early labile stages but reversibly impairs reproductive output on exposure to EDCs during non-labile adult stage. A consequence of climate change, elevated temperature, and declining oxygen and pH levels is that it masculinises genetic female fish. Fish display a remarkable ability to postpone the labile period. Besides postponement, some primary and tertiary gonochores have two distinct labile periods amenable to temperature and hormonal manipulations. Hermaphrodites have retained the period until the end of the adult stage and are capable of sex change/reversal more than once in both male and female directions.

For the first time in ichthyological literature, the author has analyzed the structure of fish populations in inland reservoirs based on absolute values of their mass. The structure of population and its changes have been examined in seven fish species from small lakes, two from large lakes, and seven from large reservoirs in plains. Special attention has been paid to the main indicator of the structure of population - correlation between the age of ichthyomass culmination and mass maturation. Data have been presented on age-related changes of ichthyomass in many generations of 11 species of commercially important fish. It is shown that populations of the investigated species of fish attain their maximum ichthyomass before reaching mass maturation or both these events are concurrent. Three types of population structure have been identified and their characteristics presented. The material presented in the book and conclusions derived are of great interest both for developments in population ecology of fish and the theory of optimal fishing. The book is intended for ichthyologists, hydrobiologists, and ecologists studying theoretical bases of fish ecology and tackling applied questions of regulated fishing and conservation of fish stocks.

Topics covered in this volume include: transformation morphology on structures in the head of cichlid fishes; the structure and function of fish liver; atretic follicles and corpora lutea in the ovaries of fishes; effects of gill dimension on respiration; and the efects of pesticides on fish.

This book provides a concise synthesis of how toxic chemical pollutants affect physiological processes in teleost fish. This Second Edition of the well-received Water Pollution and Fish Physiology has been completely updated, and chapters have been added on immunology and acid toxicity. The emphasis, as in the first edition, is on understanding mechanisms of sublethal effects on fish and their responses to these environmental stressors.
The first chapter covers the basic principles involved in understanding how fish respond, in general, to environmental alterations. Each subsequent chapter is devoted to a particular organ system or physiological function and begins with a short overview of normal physiology of that system/function. This is followed by a review of how various toxic chemicals may alter normal conditions in fish. Chapters covering environmental hypoxia, behavior, cellular enzymes, and acid toxicity are also included. The book closes with a discussion on the practical application of physiological and biochemical measurements of fish in water pollution control in research and regulatory settings.

This volume provides a unique and authoritative source of critically evaluated water quality data concerning the effects of chromium, nickel, aluminum and nitrate on freshwater fish and includes an assessment of the toxicity of mixtures. Commissioned by the European Inland Fisheries Advisory Commission, an agency of the United Nations Food and Agriculture Organisation, the reports cover all stages of life cycle and relevant trophic levels, including aquatic invertebrates and plants and potential bioaccumulation through the food chain. An extensive bibliography is provided for each chapter as well as a complete glossary of terms and fish species mentioned in the text.

This book is the most thorough exploration to date of the many ways in which a wild creature has been absorbed, reimagined and represented across the ages in all of the major art forms. The authors consider not only how the identity of sharks in the natural environment became incorporated into a cultural environment but also how sharks came to be considered the most feared creatures in the open oceans as a consequence of this incorporation. Yet sharks are especially important in helping to maintain a balance that is essential to the health of the oceans. The book begins with a treatment of the three sharks at the top of global shark-attack files from scientific, economic and environmental perspectives. Subsequent chapters engage with cultural representations of sharks in poetry, drama, art, novels, screenplay adaptations and films. Through an exploration of the ways in which sharks have been represented in human culture through the centuries, this book alerts the global community to the importance of sharks as a common cultural heritage. It aims to change perceptions of sharks so that they can become more revered than feared. The authors of this book argue that an increased understanding of sharks should lead to the development of better strategies for shark and human interactions. This book will be of great interest to researchers and students of the Environmental Humanities, Cultural History and the Arts. It is also excellent supplementary reading for courses in Zoology and Marine Science.

This volume is based on the proceedings of a conference held in Sicily, in October 1991. It illustrates the developments in the field of behavioural ecology using fishes, with new or more sophisticated ideas and techniques that offer the potential of powerful analyses of selection on behaviour.

The percid fishes (or perch family) comprise many species including the perch, pikeperch, yellow perch, walleye and the darters. These species are of great ecological and economic importance, being important components of the freshwater ecosystem and recreational and commercial fisheries.

"Percid Fishes "covers aspects such as systematics, morphology, biology, ecology, diseases and parasites and the economic importance of percid fisheries. Special emphasis is placed within the book on the complex relationship between this family of fishes and their environment and how they respond to perturbations, especially those induced by humans.

The author, John Craig who has a great deal of experience working on these fishes in many of the countries in which they occur, has drawn together an extremely important book which provides a unique, comprehensive and indispensable review of this most significant group of fish.

Humans spend more time in or on the water than ever before; we love the beach. But for many people, getting in the water provokes a moment's hesitation. Shark attacks are big news events and although the risk of shark attack on humans is incredibly low, the fact remains that human lives are lost to sharks every year. Shark Attacks explores the tension between risk and human fear and the need to conserve sharks and protect the important ecological roles they play in our marine environments. Marine biologist Blake Chapman presents scientific information about shark biology, movement patterns and feeding behaviour. She discusses the role of fear in the way we think about sharks and the influence of the media on public perceptions. Moving first-hand accounts describe the deep and polarising psychological impacts of shark attacks from a range of perspectives. This book is an education in thinking through these emotive events and will help readers to navigate the controversial issues around mitigating shark attacks while conserving the sharks themselves. FeaturesClarifies what is fact and what is fiction with regards to shark attack statistics and explains why the fear of sharks and shark attacks is so prevalent in modern society Discusses personal and regional mitigation devices and measures as well as the pros and cons of each of these Provides suggestions on how we can better manage the risk (real and perceived) of shark attack into the future Provides a range of personal accounts and public opinions on shark attack to round out our understanding of these events and to provide support for gaps in current policy

This part completes the review of the largest and economically richest order of fishes, Perciformes, begun in Part 3. It includes 12 suborders with keys and brief descriptions to 230 species, and information on their ecology and distribution.

Have you ever seen a fish that could do a handstand? This is the story of a quirky and primitive little fish that is famous for two things: walking on its 'hands' (pectoral fins), and being the first marine fish anywhere in the word to be listed on the IUCN Red List of Threatened Species. The Spotted Handfish has survived since the time of the dinosaurs - until now. Invasive seastars, pollution and climate change mean that this unique Australian is in real trouble - raise your hand if you want to know more! Hold On! Saving the Spotted Handfish is perfect for primary aged readers. Teachers notes can be downloaded for free from the CSIRO Publishing website. Marine environment story, narrated by a handfish. Showcases handfish biology and ecology, in addition to threats and their conservation plight, and importantly, how science is stepping in to save the day. Includes Fact File section and a glossary.

The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen's organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.

When the famous South African fish scientist Professor JLB Smith published Old Fourlegs - The Story of the Coelacanth in 1956 he created an international sensation. After all, this 400-million-year-old fish, known only from fossil remains, was thought to have become extinct around 66 million years ago! JLB Smith’s dramatic account of the discovery of the first and second coelacanths in 1938 and 1952 turned him into a cult figure and put South African science on the world map. His book was eventually published in six English editions and translated into nine foreign languages.

Mike Bruton’s The Annotated Old Fourlegs includes a facsimile reprint of the original book, to which he has added notes and images in the margins that provide an interesting and revealing commentary on Smith’s text, as well as new introductory and explanatory chapters that bring the coelacanth story up to date.

The genus Perca includes only three species of fish, but they are ubiquitous and abundant in freshwater and brackish environments of the northern hemisphere, from North America to Europe and Asia. These species are important both ecologically and economically. In Biology of Perch, world-renowned specialists review and update the biology of these fish. The book opens with a review of the genetic makeup of this complex assemblage from early post-glacial dispersion to the colonization of new habitats. The influences of geomorphological and biological factors on the dispersal of yellow perch (Perca flavescens) are explored. Two case studies exploit unique historical databases to follow population dynamics of yellow perch and European perch (P. fluviatilis) and to demonstrate how fisheries and habitat management can drastically influence the fate of fish populations. Three other chapters are dedicated to the general reproductive physiology, parasitology, and behavior of Perca species. The third species, the Balkhash perch (P. schrenkii), is a rare and threatened species of the Balkans, and a chapter is dedicated to its biology. The book ends with a review of the use of Perca species around the world as sentinels of ecological integrity and biomonitors in ecotoxicological studies.

This book focuses on latest information on the biology and ecology of the three bluefin tuna species: the Pacific (Thunnus orientalis), Atlantic (T. thynnus), and southern bluefin tuna (T. maccoyii). In the book, the phylogeny and basic ecological information such as early life history, age and growth, and food habits are covered. Information related to migratory ecology, and important biological aspects such as metabolism and energetics, swimming performance, schooling, visual physiology, and reproductive physiology are also included. Furthermore, new research insights about various kinds of mathematical models for bluefin tuna ecology are introduced. All the chapters are contributed by active scientists engaged in bluefin tuna research. The intent of this book is to contribute to a better understanding of the biology and ecology of bluefin tuna, and encourage undergraduate and graduate students who read this book to become bluefin tuna scientists who can contribute to further understanding of the biology and ecology of bluefin tuna.

Recent advances in fish cytogenetics have enhanced the interest in chromosome analysis in both fundamental (systematics and comparative genomics among fishes and other vertebrate groups) and applied (aquaculture, conservation and response to pollutants, whole genome sequencing of model fish species) research. Although the genomic material, the chromosomes, is basically the same in the various organisms, experience has clearly shown that fish chromosomes have to be handled with specific protocols. In laboratories around the world, traditional cytogenetic techniques and molecular cytogenetics have seen a vast improvement but the technical details and protocols are often not published in scientific journals because of constraints in format and size and therefore they are not accessible to the whole scientific community. These shortcomings are very well known to fish cytogeneticists and the idea to prepare a specific manual was first discussed during the first "Workshop of Fish Cytogenetics" held in Concarneau (France), in 1992. Resulting from the above workshop, a draft compilation of the techniques and protocols in fish cytogenetics available at that time had been produced and distributed privately, but never published. There does not exist, at present, any published handbook or manual specifically dealing with fish cytogenetics. This book fills this void by bringing together and updating the main techniques so that the traditional methods can be standardized. Moreover, this book includes novel developments or improvements; some of the protocols provided here are practically unknown to the scientific community and even now unpublished.
