ABSTRACT

Under ADCP's Fish Feed Development Programme, a survey of the availability of ingredients for fish and shellfish feeds was undertaken in 11 countries. Information on the various feed stuffs, their composition, nutritional value, prices and availability are summarized. Although some of the feed stuffs have anti-nutritional or toxic factors, the majority of them are useful as ingredients in fish and shellfish diets. Making use of the facilities in the FAO/UNDP Network of Aquaculture Centres and other projects and the nutrient specifications for cultivated species, a number of least-cost feeds using locally available ingredients were formulated, prepared and tested. A micro-encapsulated egg diet proved efficient as a larval feed for rohu, Clarias, sandgoby and Pangasius. The results of feeding experiments with fingerlings and adult fish are summarized. Based on experience so far, a number of 24-30 percent protein diets for warm water fishes and 40-50 percent protein diet for rainbow trout fry, fingerlings and adults are proposed.

The existing feed milling industries in the countries surveyed are briefly described and their ability to undertake fish feed manufacture discussed.
