Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.

Using the latest research in fish nutrition, this volume revises and combines the 1981 edition on coldwater fish and the 1983 edition on warmwater fish and shellfish. In addition to updating requirements for energy, protein, minerals, and vitamins, this book provides, for the first time, summary tables on nutrient requirements of a variety of fish species, including channel catfish, rainbow trout, Pacific salmon, carp, and tilapia. Tabular data on amino acid requirements of 11 species are also included. Shellfish are not included in this edition because of lack of scientific information.

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.

Current growth in global aquaculture is paralleled by an equally significant increase in companies involved in aquafeed manufacture. Latest information has identified over 1,200 such companies, not including those organizations in production of a variety of other materials, i. e. , vitamins, minerals, and therapeutics, all used in varying degrees in proper feed formulation. Aquaculture industries raising particular economically valued species, i. e. , penaeid shrimps and salmonids, are making major demands on feed ingredients, while relatively new industries, such as til apia farming, portent a significant acceleration in demand for properly formulated aquafeeds by the end of the present decade and into the next century. As requirements for aquafeeds increases, shortages are anticipated in various ingredients, especially widely used proteinaceous resources such as fish meal. A variety of other proteinaceous commodities are being considered as partial or complete replacement for fish meal, especially use of plant protein sources such as soybean meal. In the past five years, vegetable protein meal production has increased 10% while fish meal production has dropped over 50%, since 1989, largely attributed to overfishing and serious decline in wild stock. Throughout fisheries processing industries, traditional concepts as "waste" have given way to more prudent approaches, emphasizing total by-product recovery. Feed costs are a major consideration in aquaculture where in some groups, i. e. , salmonids, high protein-containing feeds using quality fish meal, can account for as much as 40 to 60% of production costs.

A one-of-a-kind book for researchers interested in finfish nutrition Handbook of Nutrient Requirements of Finfish provides a summary of qualitative and quantitative nutrient requirements for almost all cultured finfish for which a significant amount of nutritional information now exists. Information is presented by species and includes how each species is cultured, an index of production, regional locations where each species is being cultured, examples of purified or test diets and special conditions required for laboratory studies, nutrient requirements and practical diet formulation. Discussions of special diets and feeding practices are included for certain species. This book will be a useful guide for students, researchers, practicing nutritionists, aquaculturists, and feed manufacturers interested in fish nutrition.

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.

This book addresses current information on the effects of micronutrients and other efficacious substances from plants, animals and bacteria, with regard to quality and health of cultured fish. Each chapter contains tables, figures and is packed with many new references to help expand your knowledge of various aspects of fish culture technology. With fisheries scientists and students in mind, this book serves as a useful manual for your field of research.

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.
