Reducing feed cost is a major challenge in Aquaculture nutrition. Apart from high cost, most fish feed ingredients are also being competed for as food by man. Thus, the need for development of economic nutrient-complete diet for continuing expansion of aquaculture industry. A feeding trial was conducted to investigate the effect of mango peel meal (MPM) on growth performance of Clarias gariepinus. One hundred and twenty (120) fingerlings of C. gariepinus of average weight of 5.2±0.13g were stocked at 10 fish per plastic bowl (44L) in the wet laboratory. Four (4) iso-nitrogenous diets containing 40% crude protein in which maize was replaced by MPM at 0% (TD1), 25% (TD2), 50% (TD3) and 75% (TD4) levels were formulated. The fingerlings were fed at 5% body weight per day for 56 days. It was observed at the end of the experiment that MPM was most suitable as an energy supplement when incorporated at 25% replacement. Nevertheless, higher level of replacement with MPM above 50% decreased growth rate of C. gariepinus fingerlings. Thus this book addresses low-income group in fish farming especially in rural areas where mango peel can be utilized as catfish feed ingredient.

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.

Correct nutrition in farmed animals is essential to healthy stock and an economically sustainable high yield. In aquaculture, nutrition is particularly important as the costs of feed can be 40 or 50% of total production costs. In recent years, the aquaculture feed industry has advanced rapidly with the introduction of many commercially available feeds containing scientifically formulated and balanced diets to enhance growth and yield in specific species. Many feeds also now include ingredients aimed particularly at enhancement of stock health. The field of nutritional pathology is concerned with the study of those health disorders and ailments which result from nutrient deficiencies or dietary imbalances. This exciting new book provides an up-to-date and user-friendly practical guide on nutritional pathology in the main commercially farmed species of fish and shrimp. The book commences with an overview of the importance of nutrition in health management and the interaction between culture system, disease and the environment. The book then covers disorders in protein nutrition, lipid nutrition, mineral nutrition and vitamin nutrition. The book also encompasses comprehensive details of endogenous plant anti-nutritional factors, exogenous feed contaminants, and feed biosecurity. A Handbook of Nutritional Disorders and Diseases of Fish and Shrimp is an ideal resource for personnel within the aquaculture industry and suppliers to the industry. Particularly personnel within animal feed companies and animal health companies, especially any scientist responsible for feed formulation within animal feed companies. Fish farm managers and technicians will also find it useful, as well as companies providing fish feeding equipment, personnel within universities and research establishments where aquaculture is studied and taught, including biochemists, chemists, biological scientists, fish pathologists, food and feed scientists, nutritionists, fish veterinarians, animal scientists and aquaculture scientists. The proposed book will also provide a reference for students who are taking up courses such as Fish Nutritional Biochemistry, Fish Health, and Fish Nutrition and Feed Formulation, amongst others. 5m Books

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.
