Combination of probiotics and turmeric (Curcuma longa) to increase the survival and growth of domesticated snakehead fish (Channa striata)

The snakehead fish (Channa striata), a native freshwater species of Indonesia, is highly valued on the market and has been successfully cultivated. The purpose of this study is to determine the optimal dosage of probiotics and turmeric combination that can improve the growth and survival of farmed snakehead fish. The present study employed a fully randomized design, incorporating four treatments and three replications. The probiotics and control mixtures were administered at a dose of 0 mL/kg feed (P0), 15 mL/kg feed (P1), 30 mL/kg feed (P2), and 45 mL/kg feed (P3). Water quality, feed conversion ratio, daily growth rate, and survival rate were among the attributes assessed in the present study. Statistical analysis was performed using SPSS version 25.0 with a 95% confidence interval. The results indicate that probiotic therapy supplemented with turmeric exerts minimal effect on the growth performance or survival rate of snakehead fish (P > 0.05). The administration of probiotics containing turmeric did not improve the growth or survival of domesticated snakehead fish raised for a duration of 60 days. Further research is needed to determine the effect of administering a combination of probiotics and turmeric on the survival and growth of snakehead fish raised for a minimum of 120 days.
