""" 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.

The total aquaculture production has expanded tremendously and contributes to the world's supply of fish for human consumption in an expanding significant way. In Intensive aquaculture, the fish are quite dependent on the feed artificially provided, and the water need to be replaced or replenished at very high rates so that it can maintain the amounts of oxygen to be enough and to also remove the waste. A variety of important institutional and technological requirements depend on the ability to operate a sustainable and economic viable aquaculture. The United Nations estimates that roughly 32% of worldwide fish numbers are overexploited, depleted or recuperating and must be urgently restored. Fish farming is welcomed as a strategy to prevent overfishing. This book presents some advantages and disadvantages of intensive aquaculture, in addition to provide data and the currently situation of this type of cultivation.

The European Inland Fisheries Advisory Commission organized on 29-30 May 1980 a symposium on new developments in the utilization of heated effluents and of recirculation systems for intensive aquaculture, in Stavanger, Norway. There were six consecutive technical sessions during which the various topics were introduced and discussed. These topics referred to water quality, engineering/technology of equipment facilities, biology of cultured organisms, management/economics of rearing systems and socio-economics. A series of recommendations were made, six of them being later endorsed by the Commission at its Eleventh Session. These include (i) the establishment of a working party to analyze the problems related to fish farms effluents (ii) the activation of a correspondence group to propose terminology, format and units of measurement related to flow-through systems and to recirculation systems (iii) the preparation of a code of practice on the introduction of non-indigenous species.

Intensive tilapia co-culture is the commercial production of various species of tilapia in conjunction with one or more other marketable species. Tilapia are attractive as a co-cultured fish because of their potential to improve water quality, especially in penaeid shrimp ponds, by consuming plankton and detritus and by altering pathogenic bacterial populations while increasing marketable production. Following introductory chapters covering ecological aspects of co-culture, tilapia feeding habits, historical use, and new models, Tilapia in Intensive Co-Culture is divided into co-culture in freshwater and marine environments. Co-culture core information is presented on Vibrio control, high-rate aquaculture processes, aquaponics, tilapia nutrient profile, and tilapia niche economics and marketing in the U.S, and with carp, catfish, freshwater and marine shrimp in the Americas, the Middle East, and Asia. Tilapia in Intensive Co-Culture is the latest book in the prestigious World Aquaculture Society (WAS) Series, published for WAS by Wiley Blackwell. It will be of great use and interest to researchers, producers, investors and policy makers considering tilapia co-culture in terms of environmental and economic sustainability.

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.

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.

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).

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.
