Enrichment of live food with HUFA, specially EPA and DHA for marine fish's larviculture is necessary for increasing survival and growth rates. During this research, Artemia urmiana nauplii were enriched with ICES30/4 for 24h. The variables used in this experiment were different salinities of 12, 23 and 33ppt. and temperatures of 22, 25 and 28°C in three replications. The fatty acid contents of Artemia samples from each experiment were measured with GC. Statistic design used was completely randomized design with Dunkan's Test. Results showed rather high increase of fatty acids of EPA and DHA, this increase was from 3.1 in control to 9.18 percent for EPA at 25°C and salinity of 23ppt. (P<0.0098) and for DHA from 0 to 0.8 percent at 22°C and 33ppt. salinity. The best condition for DHA:EPA ratio is 33ppt and 28°C (P<0.11).
