ABSTRACT
In this study Artemia urmiana was used as a vector to carry probiotic Bakers yeast (Saccharomyces cerevisiae) to digestive tract of Persian Sturgeon (Acipenser persicus) larvae. The yeast (Saccharomyces cerevisiae) under the commercial title of Thepax was prepared from Doxal Co., Italy and was used for bioencapsulation of Artemia urmiana. This experiment was conducted in a completely random design. Artemia urmiana with three concentrations of Bakers yeast, 5, 5.30 and 5.48 Log CFU mL-1 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 six times a day. The control treatment were fed on unbioencapsulated Artemia urmiana. The results indicated that the Saccharomyces cerevisiae 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
