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 3 new chapters and 4 of the original chapters have new authors.

Fish Diseases: Prevention and Control Strategies provides essential information on disease prevention and treatment by the most experienced fish culturists in the industry. The book presents both traditional and novel methodologies of identifying and addressing fish disease risk, along with preventative and responsive insights to the challenges impacting fish production today. Both specific (vaccination) and non-specific (immunostimulation) approaches are explored, from maintaining optimal environmental conditions, to understanding how stressors in fish affect their immune system. Includes relevant information on government restrictions on drug usage in aquaculture to address the strict demand for fish products free of pollutants/antibiotics Presents best practices in fish farming to prevent disease and promote good health status and fish disease management Provides the most recent research on fish diseases prevention, the pathogens most studied, and options for methods of treatment

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.

Bacterial Fish Diseases: Environmental and Economic Constraints will be useful for researchers and academics who need to understand the nature and consequences of bacteria-related disease in fishes. It has in-depth information on the complete genome of various bacterial species and identifies an essential number of virulence genes that affect the pathogenic potential of the bacteria in fish. Users will find the most relevant information derived from the available bacterial genomes concerning virulence and the diverse virulence factors that actively participate in host adherence, colonization and infection, including structural components, extracellular factors, secretion systems, iron acquisition and quorum sensing mechanisms. This reference is beneficial for understanding economic losses due to bacterial pathogens in fish fauna and its impact on the economy. It addition, it provides information on good aquaculture practices and how to scientifically manage aquaculture and fishery sectors. Presents bacteria-related diseases in fish species, highlighting problems associated with the culturing of fish Discusses pollution contamination in freshwater ecosystems to provide insights into the sustainable management of fish species Provides fundamental research concepts of fish health, along with practical research methods

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 sour

Due to the recent rapid development of freshwater aquaculture in the Caucasus Region, many new and previously known fish diseases have appeared. One of the most prominent features of the region’s aquaculture is that it is mostly based on the rearing of cyprinids, mainly the common carp (Cyprinus carpio), as well as a few other predatory fish species. As a result, this book focuses on the diseases that affect these and other important warmwater fish species. Although this field guide covers the diseases of warmwater fish of Central and Eastern Europe, the Caucasus and Central Asia, it also draws upon the extensive knowledge base available for the countries of Central Europe and the former Soviet Union, as well as recent research findings from the Islamic Republic of Iran and from Turkey. The major warmwater fish species cultured in the region and their health status are discussed, and two major categories of disease are recognized: biotic and abiotic diseases. Although there are numerous biotic diseases, abiotic factors (e.g. lack of oxygen, temperature, feeding mistakes) remain the main cause of losses in aquaculture. The best practices for the field and laboratory examination of disease outbreaks are reviewed, and the importance of accurate and detailed data recording emphasized. Prevention as a key factor in avoiding the spread of disease is highlighted, and actions to prevent the spread of diseases between farms, regions, countries and continents are discussed. Possible methods for the treatment of each disease are reviewed; unfortunately, the chemicals available for use in aquaculture are now rather limited, as many of them are hazardous to both the environment and human health. Of the viral diseases discussed, spring viraemia of carp (SVC) and koi herpesvirus (KHV) pose the greatest threats to the world’s carp populations. Of the bacterial diseases, ulcer disease is still the main problem in carp culture, while among the parasites, Ichthyophthirius multifiliis, the cause of white spot disease, is among the most important. Exotic parasites such as various Thelohanellus species, as well as tapeworms belonging to the genera Bothriocephalus and Khawia, are responsible for a considerable amount of damage. Some diseases of unknown aetiology are also discussed.
