The current study was conducted to evaluate the efficiency of using Saccharomyces cerevisiae and the growth enhancer Bio Boost Aqua to improve the dietary value and productive performance of common carp, Cyprinus carpio. For this purpose, 80 fish were used, and water quality parameters were controlled during the experiment, with no mortality. The results showed significant differences between the control group and the three experimental treatments. The results also revealed a significant increase in the total protein content in the fermented diet compared to the control one. Treatments also led to a significant reduction in the fiber content of the fermented diet compared to the control. No significant difference was observed in studied diets for carbohydrates, fat, and ash percentages. There were no significant differences between treatments in the amount of feed consumed. A significant difference for treatments T2 and T3 was observed in growth performance involving final weight and weight gain. The specific growth rate was significantly superior for T2 compared to the other treatments. Feed efficiency showed a significant superiority in this parameter for T2 and T3 compared to T1 and T4 treatment. Protein consumed and protein produced values recorded a significantly superior performance for all treatments compared to the control. The results showed that the percentages of moisture and ash in muscle tissues decreased at the end of the experiment compared to the beginning. A significant difference in the percentage of protein deposited in body tissues for all treatments was observed at the end of the experiment. In contrast, the fat percentage did not show any significant differences in this parameter.
