Drawing on laboratory and farm studies, the book reviews in detail the current state-of-the-art scientific research knowledge of fish and crustacean nutrition, from larvae to juvenile fish, through to the final stages of harvesting. Topics covered include issues surrounding the formulation, manufacture and delivery of feedstuffs to fish farms and the text provides a dual focus on fish and shrimp feeding requirements addressing practical applications as appropriate for the European aqualculture industry.

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.

Fish Nutrition, Fourth Edition is an up-to-date, authoritative presentation of all key elements of the nutrition of fish and crustaceans. As aquaculture is rapidly expanding, more than 200 herbivorous and carnivorous species occupy a diverse range of ecological niches, and have therefore evolved to utilize a wide array of food sources. This new edition highlights these differences and covers the complexity and challenges associated with fish nutrition, addressing nutrient requirements to produce high-quality, healthful and sustainable resources, the essential nutrients for fish species, including proteins and amino acids, vitamins, minerals and essential fatty acids, a feed quality assessment, and fish pathology. Led by a team of international experts, this edition provides readers with new information on the use of high-throughput technologies in fish nutrition research, the role of feeds on the community structure of the microbiome, and advances in essential nutrient requirements. Features expansive updates to the previous edition, including a new chapter dedicated to diet analysis and evaluation Addresses the roles of fish nutrition and feeds on sustainability and the environmental impacts of aquaculture Covers basic nutritional biochemistry and applied nutritional topics

This study examines protein metabolism and growth in decapod crustaceans. Recognizing that successful commercial aquaculture of crustacean species is dependent on nutrition, the book focuses on the knowledge of crustacean nutritional requirements and factors affecting growth.

Fish and shellfish are contributing highly nutritious and healthy food to the food basket the world over. The world per capita seafood consumption reached a record level of 20 kg per person per year for the first time in history. This is twice the level of average per capita fish consumption in 1960s in the world. The global trade value of seafood has increased to $ 150 billion. The total fish production in the world is 150 million tons in 2014 (FAO) out of which 70 million tons is contributed by aquaculture. While the natural capture fishery resources are fast dwindling, contribution by aquaculture is ever increasing. The culture of crustaceans and finfishes is propelled mainly by intentional feeding of formulated feeds. As the demand for fish as food for human consumption is ever-increasing, aquaculture is the only alternative to bridge the gap between supply and demand. Indian aquaculture production has shown impressive growth with total aquaculture production nearing 7 million tons contributing almost 70% to the total seafood production. Indian aquaculture sector is mainly represented by the large scale culture of Indian Major Carps (catla, rohu and mrigal), exotic carps (grass carp, silver carp and common carp) and Pangasius catfish. Freshwater prawn and Penaeid shrimp are the crustaceans that are adding to seafood exports from the country. Aquaculture of Asian seabass, milkfish, mullets, grouper and cobia etc. has been gaining momentum. The total aqua feed production is touching almost 300,000 tons per annum.
