Artemia sp. plays a vital role in the natural feed used for cultivation due to its rich nutritional composition, primarily consisting of proteins and amino acids. Despite its nutritional value, the current profile of Artemia sp. falls short of being optimal for sustaining its life. To address this, a study focused on enriching Artemia sp. with ascorbic acid and fermipan during the salinity shock test. The research utilized a laboratory experimental method with a completely randomized design (CRD). The toxicity test for ascorbic acid on Artemia sp. employed the Brine Shrimp Lethality Test (BSLT) method, and the obtained toxicity values were used to determine treatment dosages. Artemia sp. enrichment involved a 3-day soaking process with seven distinct treatments, each repeated for accuracy. The salinity test subjected Artemia sp. to salinities ranging from 25 ppt to 0 ppt, recording the survival rate every 4 hours until mortality occurred. The toxicity test revealed an LC50 value of 200.84, indicating the toxic nature of ascorbic acid against Artemia sp. In the salinity shock test, Artemia sp. demonstrated varying resistance levels, with the longest survival time observed in the AS 2 treatment (20 hours), followed by FR, C1, and C2 (16 hours), AS 3, C3, and the control (12 hours), and AS 1 (8 hours). The enrichment of ascorbic acid and fermipan significantly influenced the salinity shock test, but the combination of both did not have a significant impact on Artemia sp.'s response to salinity shock.
