چکیده مقاله:

This experiment was conducted in a completely random design Daphnia magna was used as a vector to carry probiotic Baker”s yeast (Saccharomyces cerevisiae)to digestive tract of Persian Sturgeon (Acipenserpersicus) larvae. Daphnia magna with three concentrations of Baker”s yeast, 5, 5.30 and 5.48 Log CFU ml-1 in suspension of broth for 10 hours was bioencapsulated and was fed by Persian Sturgeon larvae. The Persian Sturgeon larvae were fed on the base of the 30 percent of their body weight for six times a day. The controlled treatments Were fed on unbioencapsulated Daphnia magna.The results indicated that the Saccharomyces cerevisiae promoted the 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 (p0.05). Thermal Growth Coefficient (TGC), Velocity of growth body weight (VW %) ,Food conversion efficiency (FCR) was increased significantly. The Baker”s yeast had significant positive effects on Conversion efficiency ratio (CER), and Velocity of growth body length (VL %) in comparison with control treatment (p0.05). Also the Relative food intake (RFI) significantly decreased (p0.05) while Crude Protein and Energy significantly increased (p0.05). The maximum of Lipid productive value (LPV) and Protein productive value (PPV) were obtained in treatment of T2 (the Persian Sturgeon larvae were fed on bioencapsulated Daphnia magna by 2×۱۰۸ CFU L-1). This study highlighted that the high efficiency of pension sturgeon larvae were obtained with baker’s yeast.
