Aquafeed Formulation is the only resource that provides summaries with examples and formulation techniques specifically to meet the needs of anyone in the aquaculture industry. As feed is the largest single cost item in aquaculture production, and formulating aquaculture feed requires many combinations of several ingredients and nutrient requirements, this book takes a clear-and -concise approach, providing essential information on formulation and covering relevant available software, feed nutrients, and additives such as enzymes and phytase and conjugated fatty acids, as well as best industry practices to improve aquafeed production. Users will find this to be a one-stop resource for anyone interested or involved in, the global aquaculture industry. - Includes the latest software evaluation for calculating protein and amino acid sources, trace minerals, and vitamins for aquaculture diets - Provides essential information on formulation, covering feed nutrients and additives such as enzymes and phytase and conjugated fatty acids - Presents factors affecting nutrient recommendations for aquaculture diets and nutritional effects on aquaculture nutrient excretion and water quality - Covers a broad range of techniques to understand the nutrient recommendations in the NRC guide

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.

Aquaculture, the youngest, fastest-growing, and most dynamic protein-producing industry, has the key advantage of efficient use of feed that allows farmed fish to be competitively priced compared with terrestrial proteins. Sustainable Aquafeeds: Technological Innovation and Novel Ingredients explores the present and future evolution of feeds, explains the current challenges for aquaculture, and considers how advances in technologies and ingredients can produce aquafoods for the increasing world population. International contributors to this book provide state-of-the-art information on the profile of the aquafeed industry, including factors affecting supplies and prices of key ingredients for aquafeed production. An entire set of chapters covers the scientific advances and feed industry initiatives in accordance with modern consumer trends, updating readers on the most promising strategies. These include the use of novel ingredients for nutrient supplementation and the enhancement of their use by genetic selection. The authors hope to inspire a collaboration of NGOs, researchers, and private partnerships to replace wild-caught ingredients by accelerating and supporting the scaling of innovative, alternative, aquaculture feed ingredients, including bacterial meals, plant-based proteins, algae, and yeast.

This report summarizes the proceedings and outcomes of the “Expert workshop on local alternative ingredients, aquafeed supply and feeding management” convened in Abbassa, Egypt, from 3 to 5 December 2023. The workshop brought together acknowledged aquafeed experts from African countries, governmental agencies, universities, development organizations, private industry and farmers. The workshop was jointly organized by the FAO Fisheries and Aquaculture Division (NFI) and WorldFish Egypt and hosted by the WorldFish Centre in Abbassa, Egypt. The workshop objectives were to: i) exchange and share knowledge of the use of local alternative ingredients, aquafeed supply and feeding management; ii) showcase technological advances and innovations in local alternative ingredients, aquafeed supply and feeding management; iii) identify country-specific challenges and issues in local alternative ingredients, aquafeed supply and feeding management; iv) identify national and regional needs for technical assistance and capacity building on local alternative ingredients, aquafeed supply and feeding management; and v) recommend strategies to address identified development priorities, knowledge products on local alternative ingredients, aquafeed supply and feeding management. The workshop was divided into an overview, country presentations, technical and producer sessions. The country presentation session included presentations from Cameroon, Egypt, Ghana, Kenya, Malawi, Nigeria, United Republic of Tanzania, Uganda and Zambia. The farmers’ experiences were presented by small farmers from Egypt, Kenya, Nigeria and Sierra Leone and experiences from Egyptian aquafeed industries. Following a general plenary discussion, the participants identified seven primary issues that currently constrain aquafeed production and feeding management in African aquaculture, namely: i) limited access to information on alternative feed ingredients (availability and accessibility); ii) poor feed preparation, processing, handling and storage at the farm level; iii) inadequate monitoring of on-farm feeding and farm performances; iv) inadequate investment and operating capitals for small-scale feed producers and farmers; v) inadequate knowledge and skills of farmers and extension workers in improved farm-made feed production, feeding management and farm performances; vi) poor feed quality and availability; and vii) lack of appropriate legal and policy frameworks required for sustainable aquaculture development including quality aquafeed manufacturing. Recommendations were proposed and classified under four categories: i) governance, ii) research and development, iii) capacity building, and iv) value chain.

Feed and Feeding Practices in Aquaculture, Second Edition continues to play an important role in the successful production of fish and other seafood for human consumption. This is an excellent resource for understanding the key properties of feeds for aquaculture, advances in feed formulation and manufacturing techniques, and the practicalities of feeding systems and strategies. Many new updates have been integrated to reflect recent advances within the market, including special emphasis on up-and-coming trends and new technologies on monitoring fish feeding patterns, making this book useful for anyone working in R&D in the production of feed, as well as nutritionists, farm owners and technicians, and academics/postgraduate students with a research interest in the area. - Includes new research information on using feed to enhance the sensory qualities of fish - Presents the latest research in aquafeed and processing - Provides the latest information on regulatory issues regarding feed and fish health
