The growth in the farmed production of seabass and gilthead seabream was made possible by improvements in technology for fry production in hatcheries. This volume looks at the historical background and the main factors influencing fish seed production; the life history and biology of the species and hatchery production procedures.
Volume 2: Deals with the design and production of theb hatchery, engineering aspects of water supply, hydraulic circuits, and equipment used in the hatcheries. It also includes guidance on financial aspects that could be useful for project design, and operation of hatcheries.
The aim of this book is to provide practical advice and awareness of health management and disease control in sea bass and sea bream, the most widely-farmed fish in the Mediterranean region. The prevention and control of the main pathologies affecting intensively-cultured marine fish species are of paramount importance. Farmed sea bass and sea bream are high-value fish, making significant contributions to the economies of many countries. This important book gives particular emphasis to rapid diagnosis and response to the most dangerous pathologies, which can cause severe economic losses in affected fish farms. Key features of the book Sea Bass and Sea Bream include: A clear layout and practical approach: easy to understand and implement Colour photographs of the main diseases and parasites affecting sea bass and sea bream A combination of the authors’ wide field-based experience in the diagnosis of fish diseases, with knowledge from a major fish diseases reference laboratory. 5m Books
Aquaculture is one of the fastest way to produce animal protein for growing population in the World. Aquaculture is the art, science, and business of producing aquatic plants and animals useful to humans. Fish farming is an ancient practice and date back as far as 2500 BC. In Europe, fish raised in ponds became a common source of food during the Middle Ages. Today, aquaculture plays a major role in global fish supply. Today, the global community faces financial and economic crisis, climatic changes and the pressing food and nutrition needs of a growing population with finite natural resources. As the world’s population continues to increase over the coming decades, and global living standards rise, demand for fish is set to keep on growing. With most wild capture fisheries already fully exploited, much of that new demand will have to be met from aquaculture. According to FAO estimates, more than 50 % of all fish for human consumption now comes from aquaculture. Aquaculture is one of the most resource-efficient ways to produce protein. Fish come out well because, in general, they convert more of the feed they eat into body mass than livestock animals. Salmon is the most feed-intensive farmed fish to convert feed to body weigt gain and protein followed by chicken. Aquaculture is the controlled cultivation and harvest of aquatic organisms. Most commonly grown are finfish and shellfish, but other aquatic organisms are also cultivated such as seaweed, microalgae, frogs, turtles, alligators, and endangered species. There are many similarities between aquaculture and agriculture, but there are some important differences as well. Aquaculture, like agriculture, is necessary to meet the food demands of a growing global population with diminishing natural fisheries stocks. Aquaculture and agriculture are both farming. However, aquaculture is farming in the water and therefore requires a different set of knowledge, skill, and technology.
This extensive work focuses on an important group of temperate freshwater fish, approaching the topic from the perspectives of both biology and aquaculture. It compiles the latest research on fish belonging to the Percidae family and describes in detail all biological aspects relevant to the culture of different species, including ecology, reproductive physiology, feeding and nutrition, genetics, immunology, stress physiology and behavior. It also considers commercial fish production and fish farming topics, such as protocols for induction of gonad maturation, spawning, incubation and larval rearing. Expert contributors not only provide a critical peer review of scientific literature but also original research data, and identify effective practical techniques. The book features chapters on systematics, ecology and evolution, on development, metabolism and husbandry of early life stages and on growth, metabolism, behavior and husbandry of juvenile and grow-out stages. Furthermore, the authors consider genetic improvement and domestication, as well as diseases and health management, crucial to the readers' understanding of these fish and how they can be cultured. Both researchers of percid fish biology and aquaculture professionals who are considering intensive and pond culture of percid fishes will value this timely and comprehensive handbook.)
This manual provides information on the farming of Macrobrachium rosenbergii. Many of the techniques described are also applicable to other species of freshwater prawns that are being cultured. The manual is not a scientific text but is intended to be a practical guide to in-hatchery and on-farm management. The target audience is therefore principally farmers and extension workers. However, it is also hoped that, like the previous manual on this topic, it will be useful for lecturers and students alike in universities and other institutes that provide training in aquaculture.
Ranaviruses and other viruses within the family Iridoviridae, infect a wide range of ecologically and commercially important ectothermic vertebrates, i.e., bony fish, amphibians, and reptiles, and invertebrates, including agricultural and medical pests and cultured shrimp and crayfish, and are responsible for considerable morbidity and mortality. Understanding the impact of these various agents on diverse host species requires the combined efforts of ecologists, veterinarians, pathologists, comparative immunologists and molecular virologists. Unfortunately, investigators involved in these studies often work in discipline-specific silos that preclude interaction with others whose insights and approaches are required to comprehensively address problems related to ranavirus/iridovirus disease. Our intent here is to breakdown these silos and provide a forum where diverse researchers with a common interest in ranavirus/iridovirus biology can profitably interact. As a colleague once quipped, “Three people make a genius.” We are hoping to do something along those lines by presenting a collection of research articles dealing with issues of anti-viral immunity, identification of a potentially novel viral genus exemplified by erythrocytic necrosis virus, viral inhibition of innate immunity, identification of novel hosts for lymphocystivirus and invertebrate iridoviruses, and modelling studies of ranavirus transmission. Collectively these and others will exemplify the breadth of ongoing studies focused on this virus family.
The Sparidae, commonly known as breams and porgies, is a family of fishes of the order Perciformes, and includes about 115 species of mainly marine coastal fish of high economic value, exploited and farmed for human consumption, as well as for recreational purposes. This landmark publication brings together a huge wealth of information on the biology and culture of gilthead sea bream and other Sparidae species. Commencing with an overview of the current status of aquaculture of Sparidae, the book continues with comprehensive coverage of the family’s phylogeny, evolution and taxonomy, stress and welfare issues, and reproduction and broodstock management. Further chapters include coverage of early development and metabolism, production systems, nutrition, quality, and health management. A final cutting-edge chapter looks at genomic-proteomic research in Sparidae and its application to genetic improvement. With contributions from Europe, the Middle East, Asia, Australasia and North America, carefully drawn together and edited by Professor M. Pavlidis and Dr C. C. Mylonas, themselves well known for their work in this area, Sparidae is an essential purchase for anyone working with this important family of fishes. Fish biologists, fish farmers, aquaculture researchers, and fisheries managers will all find much of great use and interest within this book’s covers. All universities and research establishments where biological sciences, aquaculture and fisheries science are studied and taught should have copies of this excellent book on their shelves.
There is considerable global interest in the culture of finfish species both for cold and warm water aquaculture development and growth. Essential information on the biology, domestication and aquacultural characteristics of a wide selection of novel and established species is provided in the form of technical sheets, species descriptions and information on current rearing practices, making this a must-have reference in the field of aquacultural science. The book also offers a basic framework in order to support investment strategies for research and developement efforts aimed at the emergence of a profitable finfish aquaculture industry and presents a rationale for species diversification, different approaches to species selection and basic economical and market considerations governing the launch of strategic development and commercialization efforts.
