AB  - In this study, <I>Artemia urmiana</I> was used as a vector to carry probiotic Baker's yeast (<I>Saccharomyces cerevisiae</I>) to digestive tract of Persian Sturgeon (<I>Acipenser persicus</I>) larvae. The yeast (<I>Saccharomyces cerevisiae</I>) under the commercial title of Thepax was prepared from Doxal Co.-Italy and was used for bioencapsulation of <I>Artemia urmiana</I>. This experiment was conducted in a completely random design. <I>Artemia urmiana</I> with three concentrations of Baker's yeast, 5, 5.30 and 5.48 Log cfu mL<SUP>-1</SUP> in suspension of broth for 10 h was bioencapsulated and was fed by Persian Sturgeon larvae. The Persian Sturgeon larvae were fed on the base of the 30% of their body weight for 6 times a day. The control treatment were fed on unbioencapsulated <I>Artemia urmiana</I>. The results indicated that the <I>Saccharomyces cerevisiae</I> could influence growth and feeding parameters in Persian Sturgeon larvae. The final body weight and Specific Growth Rate (SGR) in experimental treatments had significant difference in comparison with control treatment (p&lt;0.05). Food Convertion Efficiency (FCE) was increased significantly. The Baker&#146;s yeast had significant positive effects on Conversion Efficiency Ratio (CER), Thermal Growth Coefficient (TGC), Velocity of growth body Weight (VW%) and Velocity of growth body Length (VL%) in comparison with control treatment (p&lt;0.05). Also, the Relative Food Intake (RFI) significantly decreased (p&lt;0.05) while crude protein and energy significantly increased (p&lt;0.05). The maximum of Lpid Productive Value (LPV) and Protein Productive Value (PPV) were obtained in treatment of T2 (p&lt;0.05). This study showed that <I>S. cerevisiae</I> had high efficiency in feeding parameters and growth performance of Acipenser persicus larvae.
