Abstract :

Abstract[1]The study of Nannochloropsis oculata & Isochrysis galbana algae increase the percentage of unsaturated fatty acids, especially EPA and DHA fatty acids in Urmia Artemia (Artemia urmiana) was performed. Groups of 10-15 liters salinity, temperature in 25-26 °C, pH 5 / 8-8, 2000 lux light) with emphasis EPA and DHA, on the study and with control group (Group of hunger during the treatments enrichment), were compared. The results show that the best time Artemia nauplii for enrichment with algae about 2 hours after the yolk sac is absorbed. The best species of algae to increase the EPA was Isochrysis galbana with the 1.74 mg / g dry weight and increase DHA algae Nannochloropsis oculata with the 0.22mg/ g dry weight and ratio between DHA / EPA is: 0.12. The examples above that of the control sample is statistically significant. * Corresponding authors; Email: [e-mail]
