Abstract. Sustainable aquaculture requires innovative solutions to minimize environmental pollution and optimize resource utilization. This study investigated the potential of using wastewater from white leg shrimp (Litopenaeus vannamei) ponds to cultivate Artemia, and then using Artemia as a dietary supplement for shrimp, in order to develop a sustainable recirculating aquaculture model. The experiment consisted of five treatments, supplementing Artemia biomass (wet weight basis) at levels of 0% (control, 0% SA - Supplemented Artemia), 10% (10% SA), 20% (20% SA), 30% (30% SA), and 40% (40% SA) of the daily commercial feed, with four replicates per treatment. Shrimp were cultured in a recirculating biofilter system (200 L tank-1) at a density of 60 ind tank-1 for 40 days. The effects of dietary Artemia supplementation on growth performance, survival rate, and feed efficiency of white leg shrimp were evaluated. The results demonstrated that Artemia could be successfully cultured using shrimp pond wastewater, achieving high biomass productivity with a nutritional composition suitable for shrimp dietary supplementation. Supplementing Artemia into the diet significantly improved weight gain, biomass, survival rate, and feed efficiency of white leg shrimp. The supplementation levels of 30% SA and 40% SA improved weight gain by 2.94-7.18%, biomass by 14.54-14.89%, survival rate by 7.14 11.69%, and feed efficiency by 4.14-12.68% compared to the control (p
