This study aimed to assess the impact of incorporating dried yeast (Saccharomyces cerevisiae) on growth performance, feed utilization, body composition, blood parameters, and economical evaluation. 120 fish post-acclimatization were randomly assigned to 12 experimental aquariums. In this setup, three aquariams acted as replicates for each treatment, with an average initial weight of 28.55± 0.82g. Saccharomyces cerevisiae (Sc) levels of 0, 0.4, 0.8, and 1.2% (equivalent to 0, 4, 8, and 12g for diets D₁, D₂, D₃, and D₄, respectively) were used. The feeding trial lasted 56 days. The results revealed that diets varied in crude protein (CP) from 30.15 to 30.80% and gross energy from 4543 to 4559kcal/ kg DM. Mortality rates were 6.67% in the control and zero in the other groups. Protein efficiency ratio (PER) increased with 12g Sc/ kg^-1 diets. Serum proteins rose at this level, while ALT, AST, and uric acid peaked at 4g Sc/ kg. Body composition changed, where moisture, crude protein, and ash increased, whereas ether extract and growth energy decreased. Energy retention (ER)% decreased, while protein productive value (PPV)% was enhanced. Net improvements of 6.80, 9.47, and 19.03% were evident in D₂, D₃, and D₄, respectively, compared to controls. In conclusion, Saccharomyces cerevisiae acts as a growth promoter, especially at 12g/ kg^-1 feed. These findings illuminate the potential benefits of incorporating Sc in fish diets for enhanced performance and economic gains.
