Aquaculture Microbiology

Fish and shrimp producing industries generate huge amounts of wastes in form of viscera, scales, waste water, etc. Applications of microorganisms and/or microbesbased products have contributed significantly in solving many of these problems associated with aquaculture and waste management. This book addresses strategies for control of bacterial inf

This volume details techniques involved to study aquatic pathogens that cause infections, especially in fish. Chapters guide readers through a wide range of basic and advanced methods, viral and fungal pathogens, probiotic bacteria, treatment of pathogens using seaweed extract, medicinal plant extracts, and actinomycetes. Authoritative and cutting-edge, Aquaculture Microbiology aims to be a useful practical guide to researches to help further their study in this field.

Recent Advances in Aquaculture Microbial Technology emphasizes various topics on microbiology related technology for aquaculture development and discusses different types of microbiological applications, thus serving as an all-inclusive reference which consolidates microbial technologies adopted in the field. The book covers the history and development of microbial technology in aquaculture as well as aquaculture microbiology, diversity and the role of microbes in aquaculture systems. In addition, it presents the beneficial microbial communities in aquaculture and varying methods employed to study bacterial association in fish, microbes and fish diseases. This resource will help improve research experiments and accomplishments in the area of aqua-culturally relevant microbial technology, making it useful for researchers and scientists in the field. Describes the history and development of microbial technology in aquaculture Presents scientific methods employed to study bacterial association in fish Includes applications of microbial derived nanomaterials in disease prevention and treatment Provides information and the use of probiotics and prebiotics in aquaculture

Aquaculture is currently one of the fastest growing production sectors in the world. It now accounts for nearly half (45%) of the world¿s food fish (which refers to production of aquatic animals: fish, crustaceans, molluscs, amphibians) and this increase is expected to reach 50% in 2015. Genetic engineering and biotechnology have contributed vastly to this field. The most commonly used methods in fish biotechnology are chromosome manipulation and hormone treatment which can be used to produce triploid, tetraploid, haploid, gynogenetic and androgenetic fish.

This book sheds light on the major functions of microbial communities in aquaculture ecosystems, showing that by recycling nutrients, degrading organic matter and preventing disease outbreaks, a variety of microbes are truly beneficial to a wide range of aquaculture industries. It discusses how deteriorating environmental quality enables some microbial strains to trigger disease, describes the development of highly sustainable tools to improve water quality, and identifies crucial factors that endanger microbial homeostasis in aquaculture ecosystems. The book also covers post-antibiotic approaches for preventing and treating opportunistic microbial infections based on harnessing environmental and fish-associated microbial communities. Furthermore, it explores how manipulating and engineering these complex microbial communities using bio-agents such as probiotics, phages, natural nutritional additives, or with fine-tuned biofilters will open the door for new ways to develop a more sustainable and cost-effective aquaculture industry. Including an accessible presentation of modern high-throughput sequencing technology to identify host-microbial interactions in aquaculture ecosystems, this book is a valuable resource for scientists, aquaculture and fishery experts, sustainability enthusiasts and scholars in the areas of biology and marine agriculture.

Aquaculture Health Management: Design and Operation Approaches is an essential reference for the diverse aquaculture community. With the steadily increasing importance of healthy fish production and the expansion of the animal aquaculture industry to new geographic areas, new microbial and parasitic species with pathogenic potential continue to emerge. The book covers the broad spectrum of fish and shellfish health, the functional roles of pathogen emergence, and the impacts of nutrition and preventative medicine such as pre- and probiotics, as well as chemical treatments, relevant legislation and more. This reference takes a comprehensive approach to understanding overall fish health management, making it valuable to aquaculturists, practitioners in aquatic animal health, veterinarians and all those in industry, government or academia who are interested in aquaculture and fisheries and their sustainable futures. Presents the biosecurity measures used to prevent the spread of disease Discusses fish immunology to help readers understand preventive medicine for a healthy fish production Examines the latest scientific methods and technologies to maximize efficiencies for healthy fish production for farming Includes the most commonly researched fish, crustaceans and mollusks in aquaculture

This book has been developed to provide a detailed discussion of probiotics, which have been evaluated for use predominantly in fish and shellfish aquaculture. This book highlights strengths and weaknesses in knowledge and discusses gaps that need to be addressed. There has been a great deal of research concerning the use of probiotics in aquaculture. To date, a wide range of Gram-positive and Gram-negative bacteria and some eukaryotes, i.e. yeasts and unicellular algae, has been reported to be beneficial to aquatic hosts. Following oral uptake, benefit includes improved growth performance and protection against many bacteria and some parasitic diseases. This book will be suitable for scientists, veterinarians, professionals, and senior students involved in aquaculture.
