The availability of good feeding on fish performance is needed to improve the poor aquaculture condition. The study examines the effects of Saccharomyces cerevisiae supplementation on the growth, survival rate, and blood profile of saline red tilapia in the semi-intensive culture. Sixty saline red tilapia (4.58 ± 0.09 g) were divided into five groups and received standard feed with supplementation of S. cerevisiae at different doses: (A-E) 0, 5, 10, 15, and 20 g/kg feed. S. cerevisiae was sprayed onto the feed and given to fish three times/day for 49 days. The efficiency of feed utilization (EFU), feed conversion ratio (FCR), the protein efficiency ratio (PER), relative growth rate (RGR), survival rate (SR), and blood profiles were examined. The water quality parameters were also evaluated, including temperature, pH, dissolved oxygen, NH3, and salinity. Data were analyzed using ANOVA followed by the Duncan test. The supplementation of 10 g/kg S. cerevisiae could significantly (p<0.05) increase EFU (85.13%), PER (3.76), RGR (4.53%), and survival rate (97.53%), and decrease FCR (1.42) of the saline red tilapia. All doses of S. cerevisiae significantly (p<0.05) increased the number of hematocytes (34.68, 35.96, 34.14, and 34.52%, respectively) and hemoglobin (12.98, 13.58, 12.73, and 12.67%, respectively) of fish. The highest number of erythrocytes and leucocytes was found in dose 10 g/kg feed. All water parameters were stable during the study. Therefore, S. cerevisiae can be used as a feed supplement for red tilapia fish to increase the growth, survival rate, and blood profile of the saline red tilapia.

Abstract

The availability of good feeding on fish performance is needed to improve the poor aquaculture condition. The study examines the effects of Saccharomyces cerevisiae supplementation on the growth, survival rate, and blood profile of saline red tilapia in the semi-intensive culture. Sixty saline red tilapia (4.58 ± 0.09 g) were divided into five groups and received standard feed with supplementation of S. cerevisiae at different doses: (A-E) 0, 5, 10, 15, and 20 g/kg feed. S. cerevisiae was sprayed onto the feed and given to fish three times/day for 49 days. The efficiency of feed utilization (EFU), feed conversion ratio (FCR), the protein efficiency ratio (PER), relative growth rate (RGR), survival rate (SR), and blood profiles were examined. The water quality parameters were also evaluated, including temperature, pH, dissolved oxygen, NH3, and salinity. Data were analyzed using ANOVA followed by the Duncan test. The supplementation of 10 g/kg S. cerevisiae could significantly (p<0.05) increase EFU (85.13%), PER (3.76), RGR (4.53%), and survival rate (97.53%), and decrease FCR (1.42) of the saline red tilapia. All doses of S. cerevisiae significantly (p<0.05) increased the number of hematocytes (34.68, 35.96, 34.14, and 34.52%, respectively) and hemoglobin (12.98, 13.58, 12.73, and 12.67%, respectively) of fish. The highest number of erythrocytes and leucocytes was found in dose 10 g/kg feed. All water parameters were stable during the study. Therefore, S. cerevisiae can be used as a feed supplement for red tilapia fish to increase the growth, survival rate, and blood profile of the saline red tilapia.
