Introduction to nutrition in tropical aquaculture Millamena, Oseni M. Millamena, Oseni M.; Coloso, Relicardo M.; Pascual, Felicitas P. Fish is a vital component of food security especially in developing countries of the world. As the world population grows, the need for more food and more fish has correspondingly increased. Aquaculture, the farming and husbandry of fish and other aquatic organisms, is now a well-established industry worldwide and is the fastest growing food production sector. However, as aquaculture operations expand, the risk to the environment grows. Fish nutrition and feeding play important roles in the sustainable development of aquaculture. The efficient conversion of feed to fish is important to fish farmers because feed is the largest component of the total cost of production. Improved feed composition and better feed efficiency will result in higher fish production, lower feed cost, and low waste production hence, decreased nutrient load from fish farming.

Feeding habits and digestive physiology of fishes Borlongan, Ilda G.; Coloso, Relicardo M.; Golez, Nelson V. Millamena, Oseni M.; Coloso, Relicardo M.; Pascual, Felicitas P. This chapter provides basic information on the feeding habits and behavior, and physiology of fishes and crustaceans. The mechanisms that control the movement and digestion of food, methods of assessing digestibility of feed, factors affecting digestion and absorption of food nutrients, and feeding processes in fish are discussed. An understanding of the feeding habits, feeding mechanisms, and the digestion and absorption processes can help fish farmers and nutritionists maximize the use of feed. The rate at which fish digest their food is of primary importance in determining feeding rates, frequency, and ration size. Knowledge of the digestive physiology of fish is also necessary for an effective feed formulation and in choosing a proper feeding regime. This chapter aims to teach the reader: the feeding habits and behavior of fishes and crustaceans; the structural adaptation in the anatomy of the digestive tract; the various organs of the digestive systems of fishes and crustaceans and their functions; nutrient digestion and absorption by fishes and the fate of digested and undigested food; the factors that affect the rate of digestion and absorption; and the feeding process in fish.

Processing of feedstuffs and aquafeeds Golez, Nelson V. Millamena, Oseni M.; Coloso, Relicardo M.; Pascual, Felicitas P. This chapter will help the reader understand and appreciate the basic principles of processing, preparation, storage, and quality control in the preparation of aquafeeds. The material in this section is presented in sequence beginning with the processing of basic ingredients to remove antinutritional factors, followed by steps in feed preparation, from the easiest to the more complex processes, and storage. This chapter presents methods and equipment that are useful not only for feed millers, but also for extension workers and fish farmers.

Economics of feeding Agbayani, Renato F. Millamena, Oseni M.; Coloso, Relicardo M.; Pascual, Felicitas P. This chapter aims to introduce concepts and methods in doing economic analysis applicable in aquaculture in general with emphasis in feed production and feeding in aquaculture farms. This chapter discusses the following topics: cost of producing feeds; simple single-input (feeds) and single output (fish) production function; indices for measuring economic efficiency of feeds; the least-cost combination; and linear programming as used in the allocation of limited resources such as feed ingredients that will meet the nutritional requirements of the fish.
