Abstract

This paper describes a pilot culture system for the production of on-grown Artemia in freshwater ornamental fish farms. The system had 21 culture units, each consisting essentially of three components: an oval-shaped raceway, an air-water lift system and two waste collectors. Using artificial seawater at 20 ppt for culture and at a mean production rate of 3 kg/m3 of water in a 12-day cycle, the system had a production capacity of 8 metric tons of on- grown Artemia a year. Biochemical analyses were preformed to evaluate the nutritional value of the on-grown Artemia against three conventional live feeds, viz. live Artemia nauplii, live Moina and frozen bloodworms. Cost-benefit analysis showed that with a capital investment of US$ 82,000 and an annual cost of production of US$ 81,000, the system achieved a high internal rate of return of 88% over a 10-year period and a short payback period of 1.23 years. The availability of on-grown Artemia would not only offer farmers and exporters a better alternative live food organism for feeding to their fish, but more importantly the possibility of enhancing the fish performance and quality through bioencapsulation.
