Artemia is the most important live food in aquaculture. Considering its mass cultivation, easy usability, and nutritional value in fish farming, the effect of Spirulina platensis and Dunaliela salina algae on the growth, survival, and total protein of Artemia franciscana was evaluated. For this purpose, Artemia was cultured in laboratory conditions with a combination of yeast and Spirulina powder in five different treatments (20, 40, 60, 80, 100% Spirulina powder and yeast) compared to the control treatment (100% Dunaliela algae and yeast). The results showed that there were significant differences in growth in treatments with 40, 60, 80, 100% Spirulina powder and yeast, and survival in the 100% Spirulina powder and yeast treatment, compared to the control treatment (p<0.05). The investigation of the first molt in each treatment revealed that the 100% Spirulina powder and yeast treatment had the earliest molting time, which was consistent with the total protein content of the treatments. According to the results, the best treatment in terms of growth, survival, time to first molt, and total protein content is the 100% Spirulina powder with yeast treatment.Therefore, Artemia cultivation with Spirulina is scientifically and economically justified.
