Nutrition in tropical aquaculture : essentials of fish nutrition, feeds, and feeding of tropical aquatic species
Abstract
This book is intended to teach undergraduate students the essentials of aquaculture nutrition, feed formulation, and feeding management. It serves as a reference book for researchers in aquaculture, aquaculturists, fish farmers, and aquaculture nutritionists. For the basic understanding of the materials presented, it is essential that the students, teachers, and researchers have a good background in chemistry, fish biology, or fisheries. The book covers the subject areas of known nutrient requirements, effects of nutrient deficiencies on various aquatic species, nutrient sources, digestibility, and digestive physiology. Feed formulation, processing and storage, evaluation and quality control, feeding management, as well as the economics of feeding are included. Aspects on feeds and feeding related to the conservation of the aquatic environment are also dealt with.
Each chapter of this book has common features such as an introduction, basic concepts, and a summary. Both the basic and practical aspects of fish nutrition are included to give the students and allow the readers who are unfamiliar with the topics a clear understanding and knowledge of these concepts. Study questions at the end of each chapter serve as a guide to summarize and impress on the students the salient points of the subject matter in each chapter. To easily comprehend the subject matter, there is an appendix containing the analytical methods and a glossary of technical terms. The users particularly the students are encouraged to broaden their knowledge by referring to the list of references and suggested readings at the end of each chapter.

Formulation of aquafeeds
- In OM Millamena, RM Coloso & FP Pascual (Eds.), Nutrition in Tropical Aquaculture: Essentials of fish nutrition, feeds, and feeding of tropical aquatic species, 2002 - Aquaculture Department, Southeast Asian Fisheries Development CenterThe development of a feed that is both effective and economical for an aquaculture species in all its life stages is a continuous effort. Aquafeed development started when natural food sources in culture systems became inadequate and had to be supplemented with prepared feed. As fish stocking densities in culture increase, supplemental feeding is no longer sufficient. A complete feed that contains all the necessary nutrients in sufficient amounts to bring about good growth, survival, and reproduction is needed. Feed ingredients generally come from animal or plant sources and some are by-products of the food industry. There is no single feed ingredient or feedstuff that contains all the nutrients in adequate amounts. Thus, different feed ingredients are combined to make a feed that has the desired composition and nutrient levels. In combining various feed ingredients, it is important to know how much of each feed ingredient should be used to produce a cost-effective aquafeed. With the growth and expansion of aquaculture into a major industry, several fish species are being cultured; thus, the development of more efficient aquafeed formulations should continue. In developing cost-effective formulated diets, many important factors have to be considered. This chapter discusses these factors and the mathematical calculations in formulating a feed. It aims to enable students to formulate diets using purified and practical feed ingredients, and also to formulate effective supplemental and complete diets for aquaculture species. -

Processing of feedstuffs and aquafeeds
- In OM Millamena, RM Coloso & FP Pascual (Eds.), Nutrition in Tropical Aquaculture: Essentials of fish nutrition, feeds, and feeding of tropical aquatic species, 2002 - Aquaculture Department, Southeast Asian Fisheries Development CenterThis 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. -

Evaluation of feedstuffs and aquafeeds
- In OM Millamena, RM Coloso & FP Pascual (Eds.), Nutrition in Tropical Aquaculture: Essentials of fish nutrition, feeds, and feeding of tropical aquatic species, 2002 - Aquaculture Department, Southeast Asian Fisheries Development CenterThis chapter discusses how to evaluate feedstuffs and feeds. The results of feed evaluation will be used to ensure the production of high quality feeds for fish, crustaceans, and shellfish.
