A feeding experiment was conducted to examine the substitutability between dietary eicosapen-taenoic acid (<b>EPA</b>) and docosahexaenoic acid (<b>DHA</b>) in <i>Artemia</i> on the vitality of larval yellowtail <i>Seriola quinqueradiata</i>. The larval yellowtail (TL, 8.9mm) were fed <i>Artemia</i> containing different levels of EPA (2.3 ?? 5.5%) at the same levels of DHA (1.4%), or 5.2% of EPA without DHA for 16 days.<br>A positive relationship was found between larval vitality and EPA levels in <i>Artemia</i> with <b>DHA</b>. In terms of vitality, poor results were observed for larvae fed <i>Artemia</i> containing 5.2% of EPA alone. The vitality of larvae fed Artemia containing both EPA and DHA tended to be improved by increasing the EPA levels in <i>Artemia</i>. The vitality of larvae fed <i>Artemia</i> containing 2.3% of EPA with 1.4% of DHA was low, while it was improved when the EPA content in Artemia was increased to 4.0%. Moreover, it was also found that larval yellowtail could not convert dietary EPA to DHA.<br>These results have shown that the vitality of larval yellowtail could be improved by the combination of DHA with high levels of EPA in <i>Artemia</i>.
