The current study investigates the effect of the probiotic Saccharomyces cerevisiae BB06 on the growth performance of carp (Cyprinus carpio). The experiments were conducted in a laboratory-scale re-circulating system over an eight-week trial period. Ninety healthy carp were randomly divided into three groups and fed with fish feed containing 0% yeast biomass (control), 3% yeast biomass (YBV3%), and 5% yeast biomass (YBV5%). The fish were fed twice daily with a quantity of feed corresponding to 2.5% of their body weight. Growth performance increased significantly (p<0.05) with increasing levels of probiotic S. cerevisiae BB06. The YBV5% group performed the best in terms of the final body weight, weight gain rate of Cyprinus carpio. The mortality rate of the fish fed with the probiotic S. cerevisiae BB06 was 0%. An increase in the yeast content of the feed had a tendency to decrease in the value of the Fulton condition factor. In addition, fish fed diets enriched with S. cerevisiae BB06 showed improvements in feed conversion ratio and protein efficiency ratio. Water quality parameters were maintained at acceptable levels in all tanks during the eight-week trial period, allowing high growth rates and production of the carp. In conclusion, dietary supplementation with S. cerevisiae BB06 can improve the growth performance of carp (Cyprinus carpio).
