Download or read book Diagnosis and Control of Diseases of Fish and Shellfish written by Brian Austin and published by John Wiley & Sons. This book was released on 2017-09-25 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Approaches to Research on the Systematics of Fish Borne Trematodes written by Jitra Waikagul and published by Academic Press. This book was released on 2014-02-17 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approaches to Research on the Systematics of Fish-Borne Trematodes is a concise guide for systematic studies of the prevalence of fish-borne trematodes both in the endemic areas and experimental laboratories. It includes methods to identify species of fish-borne trematodes to enhance the precision of research studies based on the metacercarial stage. Misidentification of trematode species is a common occurrence when researchers are new to the field and have no guidance. Consequentially, sometimes publications report inaccurate prevalence rates of these parasites. This compact guide gives clear direction on: - Collection of parasites in the final hosts - Collection of cercaria from snail first intermediate hosts - Collection of metacercaria from fish hosts - Molecular identification of parasites - Systematics of fish-borne trematodes - Provides research guidelines and protocols for studying systematics of fish-borne trematodes using both morphological and molecular data - Presents keys to enable identification of metacercariae of fish-borne trematodes in the Greater Mekong subregion

Download or read book Principles of Salmonid Culture written by W. Pennell and published by Elsevier. This book was released on 1996-10-11 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: As salmonids have been reared for more than a century in many countries, one might expect that principles are well established and provide a solid foundation for salmonid aquaculture. Indeed, some of the methods used today in salmonid rearing are nearly identical to those employed one hundred years ago. Areas of salmonid research today include nutrition, smolt and stress physiology, genetics and biotechnology.The purpose of this book is to provide a useful synthesis of the biology and culture of salmonid fishes. The important practices in salmonid culture as well as the theory behind them is described. This volume will be of interest to students, researchers, fisheries biologists and managers as well as practising aquaculturists.
Download or read book Host Manipulation by Parasites written by Richard Dawkins and published by OUP Oxford. This book was released on 2012-06-07 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasites that manipulate the behaviour of their hosts represent striking examples of adaptation by natural selection. This field of study is now moving beyond its descriptive phase and into more exciting areas where the processes and patterns of such dramatic adaptations can be better understood. This innovative text provides an up-to-date, authoritative, and challenging review of host manipulation by parasites that assesses the current state of developments in the field and lays out a framework for future research. It also promotes a greater integration of behavioral ecology with studies of host manipulation (behavioral ecology has tended to concentrate mainly on behaviour expressed by free living organisms and is far less focused on the role of parasites in shaping behaviour). To help achieve this, the editors adopt a novel approach of having a prominent expert on behavioral ecology (but who does not work directly on parasites) to provide an afterword to each chapter.

Download or read book A Checklist of Host Parasite Interactions of the Order Crocodylia written by Marisa Tellez and published by Univ of California Press. This book was released on 2014-05-15 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Records of parasitism in crocodilians date back to the early 1800s, distributed among various types of published and unpublished materials. Analyzing parasite-host specificity, geographic distribution, and taxonomy can provide otherwise cryptic details about crocodilian ecology and evolution, as well as their local food web dynamics. This information is critical for improved conservation tactics for both crocodilians and their habitat. As climate change, anthropogenic conflict, and environmental pollution endanger crocodilian ecosystems, there is a need for organized information on crocodile, alligator, caiman, and gharial infectious diseases. This volume meets this need by delivering the first checklist of crocodilians and their parasites for researchers and scholars in biology, herpetology, and ecology in order to further the knowledge and study of crocodilian-parasite dynamics and improve our understanding of human impacts on ecosystems.

Download or read book Fish Diseases written by J. C. Eiras and published by . This book was released on 2008 with total page 1312 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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."--pub. desc.
