Intensive systems require a high degree of technical and management skill, enabling fish to be produced on a predictable volume basis to correspond with the needs of modern food processing and distribution. Now available in paperback, Intensive Fish Farming explains, at a level suited to both the professional and the student, the environmental requirements of fish, the different husbandry systems used, the problems of reprduction, nutrition and disease control. The editors have assembled an international team of experts to provide one of the most authoritative and comprehensive reference works available in this field, meeting the needs of both the academic and commercial world. Separate chapters consider the different aspects of successful intensification operations drawing on examples from the marine farming industry of Japan and the freshwater farming industries of the USA and Israel. A concluding chapter highlights current world trends and future prospects. The overall emphasis of this exceptional text is on the technical and economic factors which determine success in this important growth area of food production.

""" This book has been written as a guide to the management and use of formulated feeds in intensive fish and shrimp culture. While its focus is on the use of commercially pro duced feeds in intensive production systems, it is anticipated that many of the practical issues covered will be of equal interest to those fish farmers who make their own feeds and to those who use formulated feeds in less intensive systems. Feeds and feeding are the major variable operating costs in intensive aquaculture and the book is primarily in tended to aid decision making by fish farm managers in areas of feeding policy. The dramatic increases in aquaculture production seen over the past 15 years have been made possible, in large part, by gains in our understanding of the food and feed ing requirements of key fish and shrimp species. A global aquaculture feeds industry has developed and a wide range of specialist feeds is now sold. The new options in feeds and feeding systems, which are becoming available, necessitate continual review by farmers of their feeding policies, where choices must be made as to appropriate feed types and feeding methods. While growth rates and feed conversion values are the prime factors of interest to farmers, other important issues, such as product quality and environmental impacts of farm effiuents, are also directly related to feed management practices.

After agreeing on the methodology and outline of the country reports, the authors of the case studies, for each feeding strategy and farming system, analyzed demographic factors (including age and marital status, education and ownership structure), physical characteristics (average number of ponds and average pond size), and other input features (stocking strategies, feeding practices, types of feed, frequency and intensity of feeding and labour utilization). The case studies also identified the principal input costs, assessed the economic rates of return (gross and net margins), returns to labour, land and capital, gross and net total factor productivity, break-even prices and production and returns on capital for each feeding strategy. Problem areas were identified for the different farming systems.

A viable and sustainable alternative that can ensure the bridging of the yawning gap between fish supply and demand therefore lies in aquaculture which offers vast opportunities for investment. Aquaculture production can be increased substantially by adopting a technological shift from semi intensive to intensive systems of production as is the trend worldwide. This book aims at enlightening and encouraging the public to invest in fish-farming based on the use of simple technology of Water Flow-through Systems (WFS) and Water Recirculating System (WRS), for fish production in concrete tanks. The system can be set up in urban or peri- urban premises of little space that is easily manageable and adequately profitable with guaranteed good returns on investment. It targets a wide audience from school leavers to university students and graduates, civil servants, retirees and practicing fish farmers. It is a complete reference book on WFS and WRS in Africa and includes basic material on health management, fluid mechanics, monitoring & control systems, waste management, fish nutrition and aquaponics.

Keith Culver and David Castle Introduction Aquaculture is at the leading edge of a surprisingly polarized debate about the way we produce our food. According to the United Nations Food and Agriculture Organization, aquaculture production has increased 8. 8% per year since 1970, far surpassing productivity gains in terrestrial meat production at 2. 8% in the same period (FAO 2007). Like the ‘green revolution’ before it, the ‘blue revolution’ in aquaculture promises rapidly increased productivity through technology-driven - tensi?cation of aquaculture animal and plant production (Costa-Pierce 2002; The Economist 2003). Proponents of further aquaculture development emphasize aq- culture’s ancient origins and potential to contribute to global food security d- ing an unprecedented collapse in global ?sheries (World Fish Center; Meyers and Worm 2003; Worm et al. 2006). For them, technology-driven intensi?cation is an - dinary and unremarkable extension of past practice. Opponents counter with images of marine and freshwater environments devastated by intensive aquaculture pr- tices producing unsustainable and unhealthy food products. They view the promised revolutionasascam,nothingmorethanclever marketingbypro?t-hungry ?shfa- ers looking for ways to distract the public from the real harms done by aquaculture. The stark contrast between proponents and opponents of modern aquaculture recalls decades of disputes about intensive terrestrial plant and animal agriculture, disputes whose vigor shows that the debate is about much more than food production (Ruse and Castle 2002).

Integrated farming in Asia is either considered an eco-friendly good that should be preserved for environmental reasons or a poor practice that will soon be superseded by industrial aquaculture. This report finds that most livestock-fish integration is sound business conducted by entrepreneurs accessing urban markets where the price of fish is relatively low. It can be used as part of a strategy to reduce environmental impacts of intensive livestock production and to produce low-cost food. Farmers have proved adept at both developing their systems to meet their own needs and diversifying the role of ponds, fish and livestock within their complex livelihoods.

Fish culture in hatcheries and other aquacultural facilities is becoming much more intensive all over the world. The success of all kinds of fish rearing depends on the quality of management and this depends, in turn, on understanding the biology of fishes and the aquatic environment in which they live. This book directly addresses the relationship between the aquatic environment and the fishes. An understanding of this by the reader will result in a reduction of disease outbreaks through improved management.

In a scientific pursuit there is continual food for discovery and wonder. M. Shelley (1818) Genomic analysis of aquatic species has long been overshadowed by the superb activity of the human genome project. However, aquatic genomics is now in the limelight as evidenced by the recent accomplishment of fugu genome sequencing, which provided a significant foundation for comparative fish genomics. Undoubt edly, such progress will provide an exciting and unparalleled boost to our knowl edge of the genetics of aquatic species. Thus, aquatic genomics research has become a promising new research field with an impact on the fishery industry. It is notewor thy that the Food and Agriculture Organization (FAO) of the United Nations has projected that current global fisheries production will soon become insufficient to supply the increasing world population and that aquaculture has a great potential to fulfill that demand. This book, Aquatic Genomic. ~: Steps Toward a Great Future, was designed as a collection of advanced knowledge in aquatic genomics and biological sciences. It covers a variety of aquatic organisms including fish, crustaceans, and shellfish, and describes various advanced methodologies, including genome analysis, gene map ping, DNA markers, and EST analysis. Also included are discussions of many sub jects such as regulation of gene expression, stress and immune responses, sex differ entiation, hormonal control, and transgenic fishes.
