This book is a guide to the management and use of formulated feeds in semi-intensive and intensive fish and shrimp culture. Feeds represent the major variable operating costs in intensive aquaculture, and optimizing their use represents an opportunity for many farmers to increase or maintain the profitability of their enterprise. Fish farmers have an ever widening range of feed types and feeding methods from which to choose, and must carefully monitor the use of feeds in order to control costs. This book includes details of those biological, environmental, and nutritional factors which influence the feeding, growth and survival of fish and shrimp, and of which some understanding is essential in the establishment of effective feeding practices. Details are given of feed handling and storage methods, and the various methods available for feeding fish are described and their relative methods appraised. Methods for selection of the appropriate feed types, ration sizes, and feeding schedules are included, and details given of how to measure performance of feeding programs. Throughout the text reference is made to key areas of current research, and examples are drawn from different sectors of the industry to illustrate the general principles of feed management.

Aquaculture is more than a science in its infancy; it is now recognized as a viable and profitable enterprise worldwide. It will continue to grow and supply an increasingly larger percentage of fishery products consumed because the oceans are inadequately managed and their yield is unpredictable. Supply, price, and quality can be controlled more effectively when fish are cultured under managed conditions, like corn in a field. As aquaculture technology has evolved, there has been a trend toward higher yields and faster growth which has necessitated enhancing or replacing natural foods with prepared diets. In many aquaculture operations today, feed accounts for over half of the vari able operating cost. Feeding fish in their aqueous environment takes on dimensions beyond those considered in fee ding land animals; the nutrient requirements, feeding practices, and feeding environment are unique for fish. Knowledge on nutrition and practical feeding of fish is essential to successful aquaculture. This book is intended to be helpful to students, scientists, practic ing nutritionists, and aquaculturists. It covers the known nutrient requirements and deficiency effects for various fishes. It discusses nu trient sources and preparation of research and practical feeds. It gives direction for designing and conducting fish nutrition and feeding ex periments. Feeding practices for several commercially important fishes representing diverse culture systems (coldwater fish, warm water fish, crustaceans, pond cultures, and highly artificial cultures) are presented. One book, of course, cannot be all-encompassing in the area of fish nutrition and feeding.

Aquaculture is now recognized as a viable and profitable enterprise worldwide. As aquaculture technology has evolved, the push toward higher yields and faster growth has involved the enhancement or replacement of natural foods with prepared diets. In many aquaculture operations today, feed accounts for more than one-half the variable operating cost. Therefore, knowledge of nutrition and practical feeding of fish is essential to successful aquaculture. This book is not written exclusively for scientists but also for students, practicing nutritionists, and aquaculturists. It covers the known nutrient requirements and deficiency effects for different fishes, and digestion and metabolism of nutrients and energy. It discusses nutrient sources and preparation of practical and research feeds. It gives directions for conducting fish nutrition and feeding experiments. Feeding practices for salmonids, channel catfish, tilapias, shrimps and hybrid striped bass are presented. Since the first edition of this book was printed, the National Research Council of the National Academy of Sciences has revised the nutrient requirements for fish. These revisions are in the present edition. Other additions to this revised edition are chapters on nutrition and fish health, and bioavailability of nutrients. Each original chapter has been meticulously revised and updated with new information. Aquaculture is a dynamic area and new technologies are being introduced continuously; therefore, some of the material discussed in this revised edition may become obsolete quickly. Nonetheless, the material presented has been thoughtfully selected and updated to make it of maximum use to persons whose interests range from general aquaculture to animal nutrition to feed manufacture.

""" 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 rise into global prominence and rapid growth of finfish and crustacean aquaculture has been due, in part, to the availability and on-farm provision of feed inputs within the major producing countries. More than 46 percent of the total global aquaculture production in 2008 was dependent upon the supply of external feed inputs. For the aquaculture sector to maintain its current average growth rate of 8 to 10 percent per year to 2025, the supply of nutrient and feed inputs will have to grow at a similarrate. This had been readily attainable when the industry was young. It may not be the case anymore as the sector has grown into a major consumer of and competitor for feed resources. This paper reviews the dietary feeding practices employed for the production of the major cultured fed species, the total global production and market availability of the major feed ingredient sources used and the major constraints to feed ingredient usage, and recommends approaches to feed ingredient selection and usage forthe major species of cultivated fish and crustacean. Emphasis is placed on the need for major producing countries to maximize the use of locally available feed-grade ingredient sources, and, in particular, to select and use those nutritionally sound and safe feed ingredient sources whose production and growth can keep pace with the 8 to 10 percent annual average annual growth of the fed finfish and crustacean aquaculture sector.

In aquaculture, the provision of high quality aquafeeds that satisfy the nutritional requirements of the culture species and optimize growth are a prerequisite to improving production yields, lowering production costs, and improving economic returns to farmers. Under semi-intensive and intensive carp and trout culture, aquafeed costs usually account for the highest single production cost, typically accounting for 50 – 60 percent of total production costs. The aquafeeds available to farmers vary widely with respect to quality, nutritional value and cost. Depending on the feed type, production system and farmer preferences, there are multiple feed management strategies that can be adopted by farmers. In order to optimise feed use and minimise feed production costs, it is essential that farmers select appropriate feeds and optimise their on farm feed management practices. These guidelines are designed to provide farmers with practical guidance on how to select feeds and to optimise their use by implementing appropriate on-farm feed management practices. The guidelines provide an introduction to fish nutrition with a focus on the dietary nutritional requirements of commercially cultured carps and trout. The types of aquafeeds (live feeds, supplementary, farm-made and commercially manufactured feeds), their composition and nutritional value, manufacture and use are discussed. On-farm feed management practices focus on feeding methods, feed storage, and methods to optimise feed consumption (calculating feed rations, feeding frequency, assessing appetite and the feeding response).
