The study of unsaturated fatty acids in enriched adult Artemia A.franciscana

One main indicator in determining aquatic food is the amount of fatty acids. In order to achieve the best time for Artemia enrichment with fatty acids, the amount of unsaturated fatty acids in adult Artemia A.franciscana, at different times of enrichment with Spari Selco was evaluated. For the nutrition of the Artemia, a species of unicellular algae Tetraselmis suecica, was used during the nourishment. During different treatments, Artemia was exposed to enrichment solutions for 1, 2, 4 and 6 hours. Another treatment was also considered as control. Compared to the control treatment, the amount of the unsaturated fatty acids in all treatments showed a significant increase (p<0/05).This increase was even more considerable in Arachidonic acid and Docosahexaenoic acid (DHA) (p<0/05). Also in different treatments, the amount of the unsaturated fatty acids 2 hours after the enrichment showed a significant increase compared to others, and this difference was statistically quite significant (p<0/05). According to the results obtained and the statistical analysis performed, it was determined that the best time for Artemia enrichment by unsaturated fatty acids can be obtained 2 hours after the enrichment.
