Parasitic nematodes (Nematoda) represent an important group of fish parasites. Many species are highly pathogenic, often causing serious diseases or even death to their fish hosts. The significance of recognizing these parasites increases with the development of aquaculture in many countries and with transcontinental transfers of fish. A prerequisite for developing effective control measures in fish culture is the exact identification of these parasites, as well as a knowledge of their, frequently complicated, host-parasite-environment relationships. The present monograph is the first to deal in detail with all nematodes which are parasites on European freshwater fish, providing contemporary knowledge of the taxonomy, biology and ecology of these parasites. This book is divided into introductory chapters, including general morphological, biological and ecological data on fish nematodes, their pathogenicity and methods of study; systematic part/species descriptions, data on hosts, localization, distribution and life cycles and bionomy of all species systematically arranged; and a host-nematode parasite list. This publication is intended for parasitologists, veterinarians, workers in fisheries, university students. It will also be of interest to ichthyologists, museum curators and those engaged in nature conservation.

Sharks are ruthlessly efficient predators, the apex of 450 million years of evolution. They are older than trees, have survived five extinction events and are essential to maintaining balanced ocean ecosystems, but how much do we really know about their lives? The first book to reveal the hidden world of sharks, Emperors of the Deep draws upon the latest scientific research to examine four species in detail – mako, tiger, hammerhead and great white – as never before. An eye-opening tour of shark habitats ranges from the coral reefs of the Central Pacific where great whites mysteriously congregate every autumn in what researchers call a festival for sharks, to tropical mangrove forests where baby lemon sharks play in social groups and to the frigid waters of the North Atlantic, home to 400-year-old Greenland sharks, the world’s longest-lived vertebrates. McKeever also traces the evolution of the myth of the ‘man-eater’ and exposes the devastating effects of the fishing industry on shark populations: In 2018 only four people died in shark attacks while we killed 100 million sharks. At once a journey through the misunderstood world of sharks and an urgent call to protect them, Emperors of the Deep celebrates these iconic predators that continue to capture our imagination – and that desperately need our help to survive.

Sturgeons are considered living fossils, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats.

This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar)."

Among the fishes, a remarkably wide range of biological adaptations to diverse habitats has evolved. As well as living in the conventional habitats of lakes, ponds, rivers, rock pools and the open sea, fish have solved the problems of life in deserts, in the deep sea, in the cold antarctic, and in warm waters of high alkalinity or of low oxygen. Along with these adaptations, we find the most impressive specializations of morphology, physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins, sailfish and warm-blooded tunas, air-breathing in catfish and lung fish, parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover, fish are of considerable importance to the survival of the human species in the form of nutritious, delicious and diverse food. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman & Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology, zoology, ecology and physiology but an additional aim is for the books to be accessible to a wide spectrum of non-specialist readers ranging from undergraduates and postgraduates to those with an intrerest in industrial and commercial aspects of fish and fisheries."

This book represents the state-of-the-art of Antarctic fish research, as a result of multidisciplinary approaches and multinational collaborative efforts. Of particular interest is, therefore, the interaction between traditional taxonomists, evolutionary biologists, physiologists and molecular scientists. Several chapters present, for the first time, a comparative analysis between the Antarctic and Arctic ichthyofauna. The difference in the two polar environments entail important implications in the mechanisms of adaptation in fish.

This is an inspiring tour of the world's oceans and 80 of its most notable inhabitants. Beautifully illustrated, the book includes fascinating stories of the fish, shellfish and other sea life that have somehow impacted human life - whether in our medicine, culture or folklore - in often surprising and unexpected ways.

This book addresses the growing needs in deciphering the biological processes associated with fish reproduction, in view of the growth of aquaculture and the dwindling natural stocks of commercially important fish. It presents a comprehensive overview on egg production in fish, from the standpoint of the oocyte. With this view in mind, the book includes chapters on oocyte development (oogenesis), hormonal regulation and hormone receptors, formation of the egg envelopes, growth, accumulation of nutrients and maternal transcripts, maturation, hydration, ovulation and fertilization. A special emphasis is placed on using state-of-the-art tools including electron microscopy for discerning the ultra-structure of the follicle and genomic/ proteomic tools to fully understand biological basis of fish reproduction. Studies on promoting oocyte maturation, ovulation and spawning in farmed fish and preservation of fish oocytes at low temperatures are also included.

Diseases are a major threat to both wild and farmed fish. Pathogen-induced alterations in viability and growth of wild fish stocks can have implications on diversity and ecological status of aquatic ecosystems, as fish are main components of aquatic communities, and they can directly affect the exploitation of wild and farmed fish as a protein source for human consumption. Fish diseases can be a major factor influencing abundance and distribution of wild fish. Disease-related reduction of reproduction and/or age-specific survival can strongly affect wild stocks as it has been demonstrated for several species in distinct geographical locations. The book will be useful for fish farmers, managers, researchers and graduate students interested in fish diseases.

Zebrafish are widely considered an excellent modelsystem for vertebrate development. The embryo is transparent, thereby enabling visualization and use of labelling and transgenic approaches. Moreover, because of the ease of inducing new mutations in zebrafish and similarity with the human genome, this organism may be used effectively for disease studies. For example, mutant zebrafish are being utilized for testing drugs that will combat a range of human diseases, from Alzheimer's and cancer to kidney failure and congenital heart disease. For the first time, this atlas provides the research community with a complete reference for zebrafish anatomy spanning the early embryo all the way to adulthood.
The authors employ the technique of optical projection tomography (OPT), and offer a series of sections in multiple planes from each sample. The contents are organized by developmental stages, with over 200 images that contain annotations describing anatomical structures relevant to development. In addition, chapters feature explanatory text that highlights major developments in the zebrafish during each stage.
* Provides the first comprehensive anatomical resource that covers all regions of zebrafish anatomy from the larval period to adulthood.
* The over 200 images include explanatory notes
* Each chapter contains a concise description of key anatomical features that factor in zebrafish development
* Despite many years of use as a model system, until now there has never been a guide to zebrafish at the larval stage.
* The book's website contains a database of over 10k sections from different regions as well as 3D images that are interactive."

Ecomorphology is the comparative study of the influence of morphology on ecological relationships and the evolutionary impact of ecological factors on morphology in different life intervals, populations, species, communities, and evolutionary lineages. The book reviews early attempts at qualitative descriptions of ecomorphological patterns in fishes, especially those of the Russian school. More recent, quantitative studies are emphasised, including multivariate approaches to ecomorphological analysis, the selection of functionally important ecological and morphological variables to analyze, an experimental approach using performance tests to examine specific hypotheses derived from functional morphology, and the evolutionary interpretations of ecomorphological patterns. Six major areas of fish biology are focused on: feeding, sensory systems, locomotion, respiration, reproduction, and phylogenetic relationships. The 18 papers in the volume document: (1) how the morphology of bony fishes constrains ecological patterns and the use of resources; (2) whether ecological constraints can narrow the niche beyond the limits imposed by morphology (fundamental vs. realized niche); (3) how communities of fishes are organized with respect to ecomorphological patterns; and (4) the degree to which evolutionary pressures have produced convergent or divergent morphologies in fishes. A concluding paper summarizes ecomorphological research in fishes and points out taxa that are underrepresented or are especially promising for future research.

The ocean teems with life that thrives under difficult situations in unusual environments. The Extreme Life of the Sea takes readers to the absolute limits of the ocean world--the fastest and deepest, the hottest and oldest creatures of the oceans. It dives into the icy Arctic and boiling hydrothermal vents--and exposes the eternal darkness of the deepest undersea trenches--to show how marine life thrives against the odds. This thrilling book brings to life the sea's most extreme species, and tells their stories as characters in the drama of the oceans. Coauthored by Stephen Palumbi, one of today's leading marine scientists, The Extreme Life of the Sea tells the unforgettable tales of some of the most marvelous life forms on Earth, and the challenges they overcome to survive. Modern science and a fluid narrative style give every reader a deep look at the lives of these species. The Extreme Life of the Sea shows you the world's oldest living species. It describes how flying fish strain to escape their predators, how predatory deep-sea fish use red searchlights only they can see to find and attack food, and how, at the end of her life, a mother octopus dedicates herself to raising her batch of young. This wide-ranging and highly accessible book also shows how ocean adaptations can inspire innovative commercial products--such as fan blades modeled on the flippers of humpback whales--and how future extremes created by human changes to the oceans might push some of these amazing species over the edge.

This new definitive volume on fish auditory systems will interest investigators in both basic research of fish bioacoustics as well as investigators in applied aspects of fisheries and resource management. Topics cover structure, physiology, localization, and acoustic behavior as well as more applied topics such as using sound to detect and locate fish.

Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries.

This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings.

This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.

During the past two decades, fish endocrinology has witnessed exciting developments due to our increased knowledge at all levels of biological organizations, including molecular biology, cell biology, physiology and behavior. New insights into development, neurobiology, immunology and molecular genetics closely correlated with classical aspects of endocrinology and represent important contributions to our knowledge on regulatory processes of vertebrates, including fish. The purpose of this book is to overview major advances in numerous research areas of fish endocrinology. Most of the chapters not only review and discuss the state-of-the-art in the respective field, but also show perspectives of future research. The book will be of interest to scientists involved in basic fish research, comparative endocrinology, fisheries and aquaculture as well as for students of fish biology.

The Early Life History (ELH) of marine fishes in Fishing Area 31, which includes the western central North Atlantic, Caribbean Sea, and the Gulf of Mexico, has remained incomplete over the years. This certainly wasnot because of any lack of interest, but rather because of the lack of a comprehensive merging of studies that would provide us with a broad understanding, as well as identify gaps in the literature.

Early Stages of Atlantic Fishes: An Identification Guide for the Western Central North Atlantic fills the void in an exceptionally thorough fashion. Inside you will find contributions from more than 70 international experts, edited by one of the world s most respected fishery scientists. This is the definitive reference covering the ELH of those fishes found in that part of the Atlantic, which stretches across the territorial waters of more than 40 countries.

This two-volume masterwork covers the eggs, larvae, and juveniles of all families known to inhabit this area. It brings together published information of merit, plus original research results providing information designed to identify these ELH stages generally collected by plankton nets. Chapters in the volume are devoted to every one of the 214 families. Each includes a brief synopsis of the family, early life-stage identification, meristic data tables, and significant accounts of lower taxa, with one page giving detailed information and the facing page devoted to illustrations.

Genetics and Fish Breeding provides a thorough review of this important subject, highlighting species which are bred commercially, such as salmon, trout, carp and goldfish. The author, who is an acknowledged expert in this subject, has drawn together a wealth of information, providing a book which should be bought by all fish biologists, fisheries scientists, geneticists and aquarists.

The need to gather available data on the Eurasien huchen - an important salmonid species - has been forced by a plain and, unfortunately, common fact of our times: the numbers and distribution of this biggest of salmonids have begun to decline and its range has begun to shrink. A seminar on the huchen - the European form of the species Hucha hucha - held in Zilina in February 1973 as a result of a suggestion of the Section for the Conservation of Fauna of the Slovak Zoological Society, indicated very clearly the sad situation. Data on the biology of the huchen are regrettably scarce despite several recent papers (Ivaska 1951, Svetina 1962, Prawochenski and Kolder 1968) with the aim of filling this gap. Supposing that without a thorough knowledge it is practically impossible to conserve any plant or animal species, the participants of the seminar concluded that the existing knowledge on the huchen should be compiled in an exhaustive monograph. The first such outline originated in 1977 under the authorship of J. Holcik, K. Hensel and L. Skacel, and was submitted as a research report to some of the central authorities. Even during the compilation of the report it became evident, however, that there is no difference between the huchen and its relative, the taimen. Consequently, we immediately began revising our first report, which took over three years.
