Diversity of the fatty acid composition of Artemia spp. cysts from Argentinean populations

Mostrar todas las versiones(3)

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...
