The growth of male freshwater crayfish (Cherax quadricarinatus) is faster compared to female. This shows the need to prioritize the development of male individuals through sex reversal method using the steroid hormone saponin found in rujak polo (Tribulus terrestris) extract to effectively boost testosterone levels. Therefore, this research aimed to evaluate the effect of T.
terrestris extract (ETT) on the growth performance, survival rate, steroid hormone levels, and male percentage in crayfish using immersion and oral methods at doses of 0, 10, 15, and 20 mg/L, as well as 0, 50, 100, and 200 mg/kg feed. The methods were compared to positive control, namely the hormone 17α-methyltestosterone at a dose of 2 mg/L and 50 mg/kg for the immersion and oral method, respectively. A completely randomized design was used with five treatments and three replicates for each method. The results showed that giving ETT to freshwater crayfish juveniles through both immersion and oral methods had significant effects on male percentage but did not influence growth performance, survival rate, testosterone, estradiol, and glucose levels. In conclusion, the most effective treatments for producing male crayfish were 20 mg/L immersion and 200 mg/L kg oral, obtaining 57% and 68% productive levels, respectively.
