Book Description
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.

Book Description
""" 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.

Book Description
If you are looking for wide-ranging international coverage of all aspects of integrated fish forming, this is the book you need. With a carefully selected and fully interdisciplinary collection of papers from experts around the world, Integrated Fish Farming provides thorough, detailed coverage of one of the world's most important approaches to integrated farming systems. Integrated Fish Fanning places IFF in a global context, reporting on case studies of successful IFF operations, experiments to enhance IFF performance, bioeconomic survey and modeling analyses, research on farm waste use and pond ecology, socio-economic elements of IFF extension and adoption, and the bio-technical and economic aspects of adapting IFF to reservoirs, marshlands, rice paddies, and marginal habitats. With contributions from leading international authorities and in-depth information from IFF operations worldwide, this is the definitive reference on Integrated Fish Farming.

Book Description
The science of animal nutrition has made significant advances in the past century. In looking back at the discoveries of the 20th century, we can appreciate the tremendous impact that animal nutrition has had on our lives. From the discovery of vitamins and the sweeping shift in the use of oilseeds to replace animal products as dietary protein sources for animals during the war times of the 1900s-to our integral understanding of nutrients as regulators of gene expression today-animal nutrition has been the cornerstone for scientific advances in many areas. At the milestone of their 70th year of service to the nation, the National Research Council's (NRC) Committee on Animal Nutrition (CAN) sought to gain a better understanding of the magnitude of recent discoveries and directions in animal nutrition for the new century we are embarking upon. With financial support from the NRC, the committee was able to organize and host a symposium that featured scientists from many backgrounds who were asked to share their ideas about the potential of animal nutrition to address current problems and future challenges.

Book Description
Intensive Fish Culture approaches the topic of intensive fish farming bio-energetically in a comprehensive and logical sequence, defining principles applicable to any species reared intensively in any type of production system world wide. As such it is an essential text for students and tool for practitioners in aquaculture internationally. Arising from courses taught to a variety of personnel over a 30-year period, this important work has been tried and tested by students and professionals alike. Chapters include coverage of bioenergetics, respiration and osmoregulation, growth rates and feeding levels, fish rearing units, facility design, maximizing production, gas management, production theory, recirculation systems and waste management.

Book Description
The book encompasses the extensive fish farming system which is the least managed form of fish farming, in which little care is taken. This system involves large ponds measuring 1 to 5 ha in area with stocking density limited to only less than 5000 fishes/ha. No supplemental feeding or fertilisation is provided. Fish depends only on natural foods. Yield is poor (500 to 2 ton/ha), and survival is low. The labour and investment costs are low, and this system results in minimum income. An intensive fish farming system is the well-managed form of fish farming, in which all attempts are made to achieve maximum production of fish from a minimum quantity of water. This system involves small ponds/tanks/raceways with very high stocking density (10-50 fish/m3 of water). Fish are fed wholly formulated feed. Proper management is undertaken to control water quality by use of aerators and nutrition by use of highly nutritious feed. The yield obtained ranges from 15 to 100 ton/ha or more. Although the cost of investment is high, the return from the yield of fish exceeds to ensure the profit. The financial management in the intensive and extensive fish farming must be monitored by the farmers to forecast the yields. This book provide an insight on mitigation measures to be planned in advanced to minimize the losses incurred due to uneven growth rates or natural calamities. This book provides an introduction to intensive and extensive fish farming and it can be used by the undergraduates, postgraduates and research students who wish to work in the fish farming sector.

Book Description
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.
