This book is the proceedings of a meeting held in Bangkok in December 1992 on the use of farm-made feeds in Asia. It contains eleven country reviews of the topic, for Bangladesh, Cambodia, China, India, Indonesia, Malaysia, Nepal, the Philippines, Singapore, Thailand and Vietnam. Nine technical papers are also included. Three are on-farm feed preparation and feeding strategies - for carps and tilapias, for catfish and snakehead, and for marine shrimp and prawns. Five other working papers are on economics, the selection of equipment, feed ingredients, formulation and on-farm management, and supplementary feeding in semi-intensive aquaculture, all directed at farm-made, rather than commercial feeds. The ninth working paper is a regional overview of aquafeeds in Asia. An analysis of the material in the eleven country papers is also presented.

It is estimated that over 1 million tonnes of farm-made feeds are produced annually in Asia and that about one-third of Asian finfish and crustacean production is achieved partially through their use. It presents and discusses 11 country reviews of the topic, for Bangladesh, Cambodia, China, India, Indonesia, Malaysia, Nepal, the Philippines, Singapore, Thailand and Viet Nam. Nine technical papers, all directed at farm-made rather than commercial feeds, address feed preparation and feeding strategies for carps and tilapias, for catfish and snakehead and for marine shrimp and prawns; economics; the selection of equipment; feed ingredients; formulation and on-farm management; supplementary feeding in semi-intensive aquaculture; and a regional over-view of aquafeeds in Asia. Emphasis is placed on the importance of farm-made aquafeeds to aquaculture production in the region. A strong plea is made for more attention to the needs of the small-scale farmers who could or do use farm-made feeds.

Good nutrition is fundamental to the success and sustainability of the aquaculture industry in terms of economics, fish health, high quality product production and minimizing environmental pollution. This book provides a unique, complete coverage of current information on nutrientrequirements, feed formulations and feeding practices of commercially important aquaculture species cultured around the world. Each chapter contains detailed feeding information on specific species and is written by an expert nutritionist on that species. The book is of interest to those workingprofessionally in the industry, graduate level students and researchers.

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.

The aim of the symposium on which this text is based was to discuss the current practices of the fish-farming industry and search for sustainable directions for future development. Topics covered include: resources for fish food in aquaculture; genetics; and environment and aquaculture interaction.
