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, &lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt; Two successive feeding trials were set up using a control (550 µg AA g&lt;sup&gt;-1&lt;/sup&gt; DW) and two different AA-enrichment levels in &lt;i&gt;Artemia&lt;/i&gt; (1300 and 2750 µg AA g&lt;sup&gt;-1&lt;/sup&gt; 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&lt;sup&gt;-1&lt;/sup&gt; DW, which is the normal level occurring in freshly-hatched &lt;i&gt;Artemia&lt;/i&gt; . 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 &lt;i&gt;Artemia&lt;/i&gt; . It is expected that under suboptimal conditions, supplementation of high vitamin C levels might also enhance production characteristics.
