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.

When the U.S. Department of the Interior released its 1989 estimates of how much undiscovered oil and gas remain in the United States, a controversy ensued. Some members of the petroleum industry charged that the estimates were too low. This book evaluates the scientific credibility of the statistical and geological methods underlying the estimates.

""" 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.
