Abstract

In the cultivation of redclaw crayfish and nile tilapia it is known that the male has a faster growth rate than the female. Honey bee contains chrysin compounds that act as aromatase inhibitors, while the sea cucumber has bioactive compounds as natural hormone sources, so the combination of both substances expected can increase testosterone production in the masculinization of juvenile crayfish. The purpose of the study is to determine the most effective dose of honey bee in masculinization of juvenile freshwater crayfish and nile tilapia larvae combined with 2 mg/L steroid extract of sea cucumber. The experiment was designed using Completely Randomized Design (CRD) with five-dose treatment of 0, 5,10,15, and 20 ml/L honey bee with dipping method in 2 mg/L steroid extract of sea cucumber for 18 hours. Each treatment with four replications. The results indicated that the highest male formation was found in the dose of 20 ml/L honey beeat 83.75% and the lowest was in the control at 55.35% . The presentof honey bee at different doses with dipping in 2 mg/L of steroid extract have not significant effect on the percentage of the female, the individual intersex, the survival, and the growth of redclaw crayfish.
