Abstract

Masculinization is a sex reversal technique to increase the proportion of male proportion, which have higher economic value. Propolis, a natural substance containing chrysin (an aromatase enzyme inhibitor), is used as an alternative to synthetic hormones. This study conducted at the Basic Fisheries Laboratory, Study Program of Aquaculture, Faculty of Agriculture, University Sriwijaya from June to August 2023. This study aimed to determine the effect of immersion duration of Betta fish larvae in propolis solution on the percentage of male fish and larval survival rate. A completely randomized design (CRD) was applied, consisting of five treatments of different length immersion times. (P0 : control, P1 : 8 hours, P2 : 12 hours, P3 : 18 hours, and P4 : 24 hours), each with three replications. The results showed that the highest percentage of male fish (92.08%) was achieved in the 24-hour immersion treatment (P4), with a 100% survival rate after immersion and 83.33% after the rearing period. Water quality was within optimal ranges : temperature (26.2–28.5°C), pH (6.5–7.4), dissolved oxygen (3.22–3.76 mg L⁻¹), and ammonia (0.007-0.017 mg L-1) Keywords: Betta splendens, chrysin, masculinization, propolis, sex reversal
