Fish And Shellfish Pathology

There has been a continual expansion in aquaculture, such that total production is fast approaching that of wild-caught fisheries. Yet the expansion is marred by continued problems of disease. New pathogens emerge, and others become associated with new conditions. Some of these pathogens become well established, and develop into major killers of aquatic species. Diagnosis and Control of Diseases of Fish and Shellfish focuses on the diagnosis and control of diseases of fish and shellfish, notably those affecting aquaculture. Divided into 12 chapters, the book discusses the range of bacterial, viral and parasitic pathogens, their trends, emerging problems, and the relative significance to aquaculture. Developments in diagnostics and disease management, including the widespread use of serological and molecular methods, are presented. Application/dose and mode of action of prebiotics, probiotics and medicinal plant products used to control disease are examined, as well as the management and hygiene precautions that can be taken to prevent/control the spread of disease. This book will be a valuable resource for researchers, students, diagnosticians, veterinarians, fish pathologists and microbiologists concerned with the management of diseases of fish and shellfish.

This revised edition fills the need for an up-to-date comprehensive book on the biological aspects of the bacterial taxa which cause disease in fish. Since the 3rd edition was published in 1999, much has changed in the control of disease of farmed and wild fish. This book analyses all the new information, including that on new pathogens and new developments on long established diseases, such as furunculosis and vibriosis. Consideration is given to all of the bacterial taxa which have at some time been reported as fish pathogens, whether they are secondary invaders of already damaged tissue or serious, primary pathogens.

Specific diseases. Lesions of organic systems. Chemical and physical agents of disease. Nutritional diseases. Neoplasia.

Fish Diseases theme is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Diseases caused by bacteria, viruses and certain parasites, have thus far been suggested as the main culprit for declining aquaculture production and are thus deemed responsible to for huge losses amounting to billions of dollars annually. There are a number of fish diseases that are of utmost importance due to their debilitating effects on both cultured and marine fish, and includes Streptococcosis caused by a number of Steptococcus spp., Furunclosis, Vibriosis, Edwasiellosis, Mycobacteriosis, Nocardiosis, to name a few. The need to prevent and counteract the effect of these diseases is therefore of paramount importance. In recent years, we saw the increase in studies focusing on fish diseases particularly on those involved in unveiling the etiological agents of the diseases and how to properly treat or eradicate them, which often involved chemotherapy or administration of antibiotics. To lessen the use of antibiotics which arguably brings with it harmful side effects, a lot have been put into the development of effective prophylactic methods against fish diseases such as vaccines and also on finding efficient and reliable means of diagnosing the disease. The volume covers in detail the various diseases in fish and shellfish caused by bacteria and viruses. The contributing authors of each section have had extensive experience with fish diseases and have outlined what we need to know regarding a particular disease in a manner that is both easy to understand and apply. In Chapter 1, the various methods for disease diagnosis, prevention including vaccination and treatment of fish diseases are discussed. Chapter 2 includes and presents the various ways fish and shellfish protect themselves or fight off disease causing pathogens through their immune systems. Chapters 3 and 4 describe the diseases caused by bacterial pathogens in inland water (or freshwater) and marine water, respectively. These chapters include the identification of bacterial species responsible for the diseases and how to properly diagnose and treat them. Chapter 5 presents fish diseases caused by viral pathogens, their etiological agents, diagnosis and treatment.

Aquaculture Pathophysiology, Volume I. Finfish Diseases is a diverse, practical reference on finfish diseases impacting aquaculture. It is intended for the veterinarian, fish health biologist or extensionist, fish pathologist and fish health diagnostician supporting the management of major and emerging infectious and non-infectious health risks for the key temperate, subtropical and tropical finfish species of commercial and fisheries importance. This volume should be read in partnership with volume 2 on shellfish diseases as the principles and approach to the diagnosis and management of aquacultured animal species are similar and typically researchers, teachers, students, diagnostic laboratory scientists, aquaculture technicians and farmers need to be competent across both finfish and shellfish health issues. A focus on the disease process of major or emerging viral, bacterial, fungal, and parasitic infections affecting aquacultured finfish species e.g. salmonids, carp, tilapia, eel, barramundi A focus on important or emerging environmental, nutritional, genetic, deformity, toxicological, endocrine disruption and neoplastic diseases in finfish A review of the immunology of finfish relevant to a practical understanding of disease diagnosis and management An overview of laboratory diagnostic methods relevant to detection of finfish diseases Concise discussion on the diverse risk factors of finfish diseases and options for their control

This Second Edition has been expanded to two volumes, the first of which focuses on marine fish. Volume 1 reviews the important diseases of wild, captive, or cultivated fish species, fish immunology, the effects of disease on populations, and public health aspects of fish diseases. Fishery scientists and managers, marine biologists, marine ecologists, and marine aquaculturists will find this volume indispensable. Principal Diseases of Marine Fish and Shellfish examines: Important diseases of marine fish and shellfish The effects of disease on wild and cultivated populations of fish and shellfish How fish and shellfish resist invasion by potential pathogen The influence of coastal/estuarine pollution on fish and shellfish disease The public health implications of fish and shellfish diseases

This second edition of the book Fish Diseases and Disorders, Viral, Bacterial and Fungal Infections volume 3 represents a major update on the viral, bacterial and oomycete disorders of finfish and shellfish. Since publication of the first edition (in 1999), considerable advances have been made and therefore all the chapters have been thoroughly revised. The new and more eloquent research and current techniques have extended our knowledge and understanding of these infectious organisms. Researchers from Europe, North America, Australia and Asia have been involved in updating this book. With the addition of new information, some of the older texts in the original chapters have been condensed; this is to ensure a more focused and comprehensive reviews. For this edition, deletion and/or combination a couple of the original chapters, have been made and added three new chapters (Chapter 6 on 'Alphaviruses', Chapter 7 on 'Oncogenic Viruses' and Chapter 21 on 'Genomics of Finfish and Shellfish Microbial Pathogens'), which have been written by new authors. There are 22 new authors who have offered to write new chapters and/or update many of the original chapters. The aims, philosophy, focus, audience and format of this second edition have remained unchanged, and the authors hoped that this edition will continue to be useful to colleagues.

Expanded and updated, this second edition considers fish diseases in the context of the fish's environment, and includes coverage of many aspects of microbiology. The authors provide information on the structure of fish in order to help familiarize readers with general fish anatomy. All the bacterial taxa which have been reported as fish pathogens are included, and the material is subdivided for easy reference into sections which deal with characteristics of the diseases, isolation methods, characterization of the pathogens, diagnosis, epizootilogy, pathogenicity mechanisms and control. Written by bacteriologists for microbiologists, the book tabulates the identification procedures, and gives characteristics of pathogens, the diseases and their control. As farmed fish are of greater commercial importance, and the consequences of losses attributable to bacterial fish pathogens therefore of greater economic consequence, the authors concentrate on these rather than on wild stocks.
