Book Description
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.

Book Description
This book is open access under a CC BY-NC 2.5 license. The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010. Unfortunately, baseline assessments of the status of habitats and biota in the Gulf of Mexico before these spills either were not available, or the data had not been systematically compiled in a way that would help scientists assess the potential short-term and long-term effects of such events. This 2-volume series compiles and summarizes thousands of data sets showing the status of habitats and biota in the Gulf of Mexico before the Deepwater Horizon Oil Spill. Volume 2 covers historical data on commercial and recreational fisheries, with an analysis of marketing trends and drivers; ecology, populations and risks to birds, sea turtles and marine mammals in the Gulf; and diseases and mortalities of fish and other animals that inhabit the Gulf of Mexico.

Book Description
This checklist summarizes information on the parasites of Philippine fishes contained in the world literature dating from the earliest known record (de Blainville 1822) to the end of 1996. Information is presented in the form of parasite-host and host-parasite lists. Included are 201 named species of parasites, distributed among the higher taxa as follows: Apicomplexta - 1, Ciliophora - 16, Mastigophora - 2, Microspora - 1, Myxozoa - 9, Trematoda - 90, Monogenea - 22, Cestoda - 6, Nematoda - 20, Acanthocephala - 5, Mollusca - 1, Branchiura - 2, Copepoda - 21 and Isopoda - 5. Also included are many records of parasites not identified to species level. Parasites have been reported from 172 of the more than 2030 species of marine and freshwater fish occurring in Philippine waters, and from another 17 species of freshwater aquarium fish examined in the Philippines but not found in natural waters. The Parasite-Host List is organized on a taxonomic basis and provides information for each parasite species on the environment (fresh water, brackish water, marine), the location (site of infection) in or on its host(s), the species of host(s) infected, the known geographic distribution (by island) in the Philippines, and the published sources for each host and locality record. The Host-Parasite List is organized according to the taxonomy of the hosts, and includes for each host, the English language and local (typically Tagalog) common names, environment (fresh water, brackish water, marine), status in the Philippines (native or exotic), and information on the known Philippine distribution of the parasites. Both lists are accompanied by remarks and footnotes, as warranted, giving specific information on points of systematics, nomenclature, possible misidentifications, introductions, pathogenicity, etc. Citations are included for all references and a supplementary list of references contains other literature on Philippine fish parasites. Parasite and host indices are included. The following new taxonomic combinations are made: Prosorhynchoides philippinorum (Velasquez, 1959) n. comb., for Bucephaloides philippinorum Velasquez, 1959; Prosorhynchoides sibi (Yamaguti, 1940) n. comb., for Bucephaloides sibi (Yamaguti, 1940); Genolinea awa (Yamaguti, 1965) n. comb., for Pseudobunocotyla awa Yamaguti, 1965; and Procamallanus (Spirocamallanus) philippinensis (Velasquez, 1980) n. comb., for Spirocamallanus philippinensis Velasquez, 1980.

Book Description
This book follows on from the first volume, on protozoan and metazoan infections, of a three-volume series. It focuses largely on finfish and considers non-infectious disorder of development, growth and physiology of wild and captive species. Various sections address topics such as tumourigenesis, stress physiology and the effects of stressors on particular processes, and the effect of environmental factors (including toxic substances) on fish health. The economic implications of non-infectious disorders in intensive aquaculture are of particular importance, and a chapter is devoted specifically to this. The final chapter describes evaluation methods for the assessment of disorders at the individual, population and community level. The book is indispensable for zoologists, veterinary scientists and those concerned with fisheries and aquaculture.

Book Description
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.
