Resumo: |
The effects of high levels of ascorbic acid (AA) delivered through enriched live food has been verified through the successful culture of larval giant freshwater prawn, <i>Macrobrachium rosenbergii</i> Two successive feeding trials were set up using a control (550 µg AA g<sup>-1</sup> DW) and two different AA-enrichment levels in <i>Artemia</i> (1300 and 2750 µg AA g<sup>-1</sup> DW). Under standard culture conditions, no differences in growth nor survival could be observed demonstrating that the nutritional requirements are below 550 µg AA g<sup>-1</sup> DW, which is the normal level occurring in freshly-hatched <i>Artemia</i> . However, a significantly positive effect could be demonstrated on the physiological condition of the postlarvae, measured by means of a salinity stress test, when vitamin C-boosted live food was administered. Since the AA levels in the predator larvae are linked with the enrichment levels in the live prey, it may be assumed that a positive influence on stress resistance was caused by feeding vitamin C-enriched <i>Artemia</i> . It is expected that under suboptimal conditions, supplementation of high vitamin C levels might also enhance production characteristics.
