This study focused on testing Artemiasp. zooplankton saturation with freshwater microalgae biomass and then using this method to correct the nutritional composition of Artemia. Accordingly, the influence of three species of microalgal monocultures was analyzed (2 freshwater – Desmodesmus armatus(Chod.) Hegew. and Chlorella vulgarisVeijerinck; one halophilous – Dunaliella viridisTeodor.). The algal monocultures were applied once in a quantity of 2-3 × 106cells × l−1for each 200,000 Artemiaindividuals hatched. The control group Artemiadid not receive algae. The enrichment process lasted 24 h, and control measurements were performed every 6 h. The survival of Artemianauplii, their proteolytic activity, and the content of proteins, lipids, and carotenoids were analyzed. The choice of algae species for Artemiaenrichment was guided by the size of the algal cells and their biochemical composition. Selected algae contained about 50% protein, 20% lipid, and 12 mg of carotenoids per g of dry weight. Using algae to saturate the Artemianauplii permitted reducing their mortality during the 24 h enrichment regime. The introduction of C. vulgarisbiomass halved this value. The use of algae also increased the proteolytic activity in Artemianauplii and the content of proteins, lipids, and carotenoids in their biomass. The best results of the bioencapsulation of Artemia nauplii with algae was with the C. vulgarisbiomass. |
