This book puts emphasis on the isolation, taxonomy, diagnosis (phenotypic, serology and molecular biology), epizootiology, pathogenicity mechanisms, and methods of disease control (by vaccination, immunostimulation, probiotics, prebiotics, plant products, and antimicrobial compounds. Co-infections, which are attributed to more than one microbial species have been discussed. Shortcomings in knowledge have been highlighted. This sixth edition is the successor to the original version, first published in 1987, and which fills the need for an up-to-date comprehensive text on the biological aspects of the bacterial taxa which cause disease in finfish. The book is primarily targeted at researcher workers, including postgraduate students, and diagnosticians. It is anticipated that the readership will include veterinary microbiologists, public health scientists and microbial ecologists.

The economic importance of bacterial fish diseases and the increased understanding of the taxonomy and pathology of fish that has occurred during the last ten years, has resulted in this completely revised and updated edition of Biological Fish Pathogens, first published in 1987. The book provides comprehensive coverage of bacterial fish pathogens and, crucially, diagnostic methods of identification and techniques for isolating those pathogens. The authors also discuss methods used to control bacterial fish diseases, and consider possible future trends in the study of pathogens. Finally, they review the emerging role of fish pathogens in human diseases. The book will be welcomed by practising aquaculturists, veterinary microbiologists, researchers in industry and in academia. It is an essential reference work for graduate and post-graduate students working in the areas of fish health.

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.

The steady growth of fish culture helps to ensure a stable supply of fish for human consumption. However, when compared with capture fisheries, production from fish culture is greatly influenced by fish diseases. Outbreaks of fish diseases have caused great economic loss to fish culture. Research has been conducted to understand and reduce the occurrence of fish diseases in fish culture. In Hong Kong, bacterial infection is the most common cause of fish diseases. This project is therefore directed to isolate and identify the causative bacterial pathogen of some fish disease cases with the aim of setting up a local fish disease database for assisting the identification of diseases and improving the understanding of fish diseases in fish farms in Hong Kong. In this project, seven fish disease cases caused by bacteria were investigated with the AFCD officials in Hong Kong. Nine fish disease bacterial pathogens were isolated and identified using different methods (including commercial biochemical test kits, automated system and DNA sequencing). The bacteria identified included Aeromonas hydrophila, Lactococcus garvieae, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus iniae, Vibrio vulnificus and Aeromonas salmonicida. Sensitivity tests to 10 common antibiotics conducted for the identified bacteria showed that spectinomycin is the most broad spectrum antibiotics. In addition, a long-term physical storage of bacterial stock with glycerol and glass beads was established for further research of the identified bacteria. For efficient data analysis, an electronic database using Microsoft Access to hold the identification results and case history of each isolated bacteria was developed. Different data entry forms and reports were also constructed to facilitate easy data entry and data access for users. The three bacteria identification methods were compared for their efficiency and accuracy. Some limitations encountered in this project including time constraints and low accuracy of some biochemical identification tests were discussed and recommendations to overcome these limitations and improvements to the constructed database were made.

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.

FISH DISEASES

The volume covers in detail the various diseases in fish and shellfish caused by bacteria and viruses.

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.

The increase in aquaculture operations world-wide has provided new opportunities for the transmission of aquatic viruses and bacteria and the occurrence of diseases remains a significant limiting factor for aquaculture production and for the sustainability of biodiversity in the natural environment. Fish diseases are demarcating one of the roles as an anticipatory factor in fish production and instigating heavy mortalities especially in hatcheries thus affecting profit negatively. Both researchers and farmers in Aquaculture area are looking for a ways to get maximum amount of yield from per unit volume of water to lower the coast in aquaculture operations. The growing global demand for seafood together with the limited capacity of the wild-capture sector to meet this demand has seen the aquaculture industry continue to grow around the world. A vast array of aquatic animal species is farmed in high density in freshwater, brackish and marine systems where they are exposed to new environments and potentially new diseases.This novel guide integrates up-to-date information about the major bacterial and viral pathogens of notable fish species; reviews major well-established fish pathogens as well as new, evolving and notifiable diseases; and covers the latest research contributed by world renowned authors and researchers. The chapters mainly focus on the epidemiology, prevalence, distribution, transmission, physiopathology, clinical signs, diagnosis, prevention, control strategies, legislative aspects and economic impact of bacterial and viral diseases of fishes. For this purpose peer reviewed scientific articles, theses and dissertations, convention proceedings, government records as well as recent books, were used as a source to compile dispersed literature.
