Diversity of the fatty acid composition of Artemia spp. cysts from Argentinean populations
Nauplii of the branchiopod crustacean Artemia spp. are widely used as live food in aquaculture. Their nutritional value depends essentially on the fatty acid profile of their lipids, which can be very variable. Study of this variability (often species- and/or ecology-related) proposes interesting th...

Nauplii of the branchiopod crustacean Artemia spp. are widely used as live food in aquaculture. Their nutritional value depends essentially on the fatty acid profile of their lipids, which can be very variable. Study of this variability (often species- and/or ecology-related) proposes interesting theoretical and applied questions. In the present study, cysts (dehydrated dormant eggs) from Argentinean Artemia spp. populations were analysed for their fatty acid profile. Most of the cyst samples analysed (n = 16) were obtained from Artemia persimilis populations, but 3 belonged to A. franciscana. Previous research indicated that A. persimilis populations are confined to inland biotopes, but in this study we report the presence of A. persimilis populations in coastal ecosystems. Cysts from all populations exhibited fatty acid profiles typical of either marine or freshwater, irrespective of the inland or coastal origin of their biotope. This study represents the first time that a significant amount of eicosapentaenoic acid (EPA, 20:5n-3) was detected in A. persimilis cyst samples.
