Abstract This study focused on testing Artemia sp. zooplankton saturation with freshwater microalgae biomass and then using this method to correct the nutritional composition of . Accordingly, influence three species microalgal monocultures was analyzed (2 – Desmodesmus armatus (Chod.) Hegew. Chlorella vulgaris Veijerinck; one halophilous Dunaliella viridis Teodor.). The algal were applied once in a quantity 2-3 × 10 6 cells l −1 for each 200,000 individuals hatched. control group did not receive algae. enrichment process lasted 24 h, measurements performed every h. survival nauplii, their proteolytic activity, content proteins, lipids, carotenoids analyzed. choice algae guided by size biochemical composition. Selected contained about 50% protein, 20% lipid, 12 mg per g dry weight. Using saturate nauplii permitted reducing mortality during h regime. introduction C. halved value. use also increased activity biomass. best results bioencapsulation
