Fish Nutrition Metabolism And Physiology

Fish Nutrition aims to present the state of knowledge of basic and applied nutritional requirements of fishes. Most of the information found in this book involves salmonids, their nutrition, and metabolism of nutrients. This is in view of the fact that more research has been done and completed with this fish. Although applied fish nutrition is a very broad field, this book focuses on some of its aspects. These include the classes of nutrients and requirements for several types of fishes. This book comprises of 11 chapters. The first few chapters deal with the general nutrient requirements of fishes. Then, other chapters discuss calorie and energy as well as micro- and macronutrient needs and requirements. The following chapters deal with the non-nutrient components of the diet, or those that influence the characteristics of food products including texture, odor, flavor, and color. Other topics covered are enzymes and systems of intermediary metabolism (Chapter 6); feed formulation and evaluation (Chapter 7); and salmonid husbandry techniques (Chapter 9). Nutritional fish diseases are also discussed in this book. Some of these diseases include thyroid tumor, gill disease, anemia, lipoid liver degeneration, and visceral granuloma. In Chapter 11, the relationship of nutrition and pathology is given emphasis. This chapter also tackles the diet and general fish husbandry. This topic is very important, because an adequate diet for fish husbandry is the foundation of fish farming.

Principles of Nutrition and Metabolism in Fish and Crustaceans is a solid reference of the most recent advances and fundamental subjects in nutrient metabolism, intestinal transport, and physiology of taste in fish. 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 as well as provides directions for conducting fish nutrition and feeding experiments. This book addresses current topics of interest to researchers and nutritionists in aquaculture research, the feed and allied industry. It is written by an international group of experts and contains fresh approaches of both classical and modern concepts of animal nutrition will be emphasized throughout the book useful to readers in various biological disciplines to integrate biochemistry and physiology with nutrition, health, and disease in fish and crustaceans. All chapters will clearly provide the essential literature related to the principles of fish nutrition and physiology useful for academic researchers with great interest to those working professionally in the aquaculture industries, graduate level students and researchers. This book can be an excellent reference for professionals and a comprehensive textbook for senior undergraduate and graduate students in aquaculture, fish nutrition and physiology, animal science, biochemistry, biology, food science and nutrition. Presents the most recent advances in the field over the last decade Includes all nutritionally balanced, environmentally sound and cost-effective feed for finfish and crustaceans Provides comprehensive coverage related to nutrition and metabolism of finfish and crustaceans: From fundamental nutritional concepts, to digestive physiology and nutrient requirements

This third edition of Fish Nutrition is a comprehensive treatise on nutrient requirements and metabolism in major species of fish used in aquaculture or scientific experiments. It covers nutrients required and used in cold water, warm water, fresh water, and marine species for growth and reproduction. It also highlights basic physiology and biochemistry of the nutrients and applications of these principles to scientific and practical diet formulations and to manufacturing techniques for major species used worldwide in aquaculture. *Nutrient requirements for dietary formulations for fish farming*Digestive physiology*Comparative nutritional requirements of different species*Fish as unique animals for certain metabolic pathways

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.
