2. Feed formulae

Some examples of feed formulae for the pond rear ing of freshwater are given in Annex 9, Tables 1- 7. Please note that these formulae are only examples; many other feeds have been used, or are possible, depending on the availability of raw materials. These examples have been extracted from D’Abramo and New (2000), where the origi nal references are cited. Diets 1-4 are practical feeds that have actually been used in freshwater prawn grow-out. Diets Nos. 5-12 have been used in experimental work.

Farm-made feeds need to be dried if not fed directly after manufacture; this can be done by spreading the feed out on concrete or on trays for sun-drying (Brazil)

Feed that has been extruded through a mincer and sun-dried is easy to transport to the ponds (Thailand)

If you are only making small quantities of feed, you can construct a solar drier that will protect it from rain showers and contamination by terrestrial animals and birds, as well as decreasing the loss of some vitamins caused by exposure to UV light
