摘要：Sustainable development of Vaname shrimp aquaculture in the future depends on several things, one of which is the availability of the male parent in a sufficient quantity. Regarding this problem, sex reversal can be performed as the solution. Sex reversal is a technique of sex genetic differentiation to change sexes artificially from males genetically into phenotype females or vice versa. This research was intended to obtain the maximal mono-sex (single sex) male of Vaname shrimp using 17α-methyltestosterone (MT) hormone through sex reversal technology to the limited sex change in Vaname shrimp, in which to date the Vaname male parent gained is still dependent on natural selection. This research used a descriptive and experimental method. The experimental research design used was a completely randomized design (RAL – Rancangan Acak Lengkap). The treatment given was immersing the shrimp larvae in 17α-methyltestosterone (MT) for 8 hours at different doses of 0 mg/L, 5 mg/L, 8 mg/L, and 12 mg/L. The immersion of the post-larvae (PL1) of Vaname shrimp using the 17α-methyltestosterone hormone gave a significant result (P < 0.05) on all of the treatments and control in which the highest percentage of male Vaname shrimp was obtained from the treatments with 8 mg/L and 12 mg/L doses, respectively reaching 64% and 66.7%. As for the weight growth, the immersion of the post-larvae (LP1) growth of Vaname shrimp using 17α-methyltestosterone hormone provided a very significant result (P < 0.05) on all the treatments and control in which the highest weight growth (weight gain) and Specific Growth Rate of Body Weight (SGR BW) were shown by the treatments with 8 mg/L and 12 mg/L doses, respectively reaching 1.5415 grams and 1.5871 grams.
