Artemia franciscana commonly referred to as brine shrimp, is widely utilized in aquaculture for its high nutritional value and adaptability to hypersaline environments. This study investigated how varying salinity levels (80, 100, 120, and 140 gL⁻¹) affect the reproductive success of A. franciscana, specifically the production of nauplii and cysts. Cultures were maintained under controlled laboratory conditions, and reproductive output was observed over seven days using 16 falcon tubes (four replicates per treatment). Results showed that lower salinity levels (80 and 100 gL⁻¹) favored higher nauplii production, indicating increased ovoviviparous reproduction. In contrast, higher salinities (120 and 140 gL⁻¹) resulted in increased cyst production, suggesting a stress-induced shift toward oviparity. The overall reproductive success, combining both cysts and nauplii, was highest at 100 gL⁻¹, implying an optimal salinity range for balanced reproductive output. These findings offer practical insights into optimizing Artemia culture for hatchery use, supporting sustainable aquaculture practices in salinity-variable environments.
