| This paper describes a pilot culture system for the production of on-grown <i>Artemia</i> 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/m<sup>3</sup> of water in a 12-day cycle, the system had a production capacity of 8 metric tons of on- grown <i>Artemia</i> a year. Biochemical analyses were preformed to evaluate the nutritional value of the on-grown <i>Artemia</i> against three conventional live feeds, viz. live <i>Artemia</i> nauplii, live <i>Moina</i>... |
