Resumo: | Three separate enrichment trials compared the &lt;i&gt;n&lt;/i&gt;-3 highly unsaturated fatty acid (HUFA) levels in &lt;i&gt;Artemia franciscana&lt;/i&gt; nauplii (Great Salt Lake, USA) as a function of the &lt;i&gt;n&lt;/i&gt;-3 HUFA level in the emulsion (30% and 50%), the enrichment dose (0.05, 0.1, 0.2, 0.3 and 0.4 g1-1) and the degree of dilution of a high HUFA emulsion with an &lt;i&gt;n&lt;/i&gt; -3 HUFA-free emulsion (100/0, 50/50, 25/75, 12.5/87.5 and 0/100, HUFA-rich/HUFA-free, w/w). The standard emulsions were distributed by the International Council for the Exploration of the Sea, Working Group on the Mass Rearing of Juvenile Fish (ICES). After the 48-h enrichment, the content of docosahexaenoic acid (DHA), eicosapentaenoic acid EPA) and total &lt;i&gt;n&lt;/i&gt;-3 HUFA increased to 23.1, 46.4, and 74.3 mg g-1DW, respectively, in &lt;i&gt;Artemia&lt;/i&gt; enriched with ICES 50 (50% &lt;i&gt;n&lt;/i&gt;-3 HUFA) and to 14, 41.4, 59.9 mg g&lt;sup&gt;-1&lt;/sup&gt; DW in nauplii enriched with ICES 30 (30% &lt;i&gt;n&lt;/i&gt;-3 HUFA). After the 12-h enrichment, the highest enrichment level of DHA, EPA and total &lt;i&gt;n&lt;/i&gt;-3 HUFA was observed at the 0.4 g 1&lt;sup&gt;-1&lt;/sup&gt; dose (12.7, 30.2 and 45.3 mg g&lt;sup&gt;-1&lt;/sup&gt; DW, respectively) After the 24-h enrichment, the highest enrichment levels were, however, found at the 0.3 g1&lt;sup&gt;-1&lt;/sup&gt; dose, i.e., respectively, 28.9, 53.2 and 85.6 mg g&lt;sup&gt;-1&lt;/sup&gt; DW as compared to 21.7, 51.1, and 75.9 mg g&lt;sup&gt;-1&lt;/sup&gt; DW at the 0.4 g 1&lt;sup&gt;-1&lt;/sup&gt; dose. After 12 h enrichment, no significant difference in &lt;i&gt;n&lt;/i&gt;-3 HUFA levels was found among the 100/0, the 50/50 and the 25/75 treatments. After 24 h enrichment, the content of DHA in nauplii of the 100/0 treatment was twice that of the 50/50 treatment (20.2 vs. 9.3 mg g&lt;sup&gt;-1&lt;/sup&gt; DW), which was in turn five times higher than in the 12.5/87.5 treatment.
