Abstract

In the cultivation of freshwater crayfish of red claws (Cherax quadricarinatus) it is known that male has a faster growth rate than female. Honey bee contains chrysie compounds that act as aromatize inhibitors, while the gamma sea cucumberer it has bioactive compounds as natural hormone sources, so the combination of both expected can increase testosterone production in the masculinization of juvenile crayfish. This study aims to determine the most effective dose of honey bee in masculinization of freshwater juvenile crayfish combined with immersion in steroid extract of 2 ppm gamma sea cucumber. The experiment was conducted with Completely Randomized Design (CRD) that was 5 treatment of honey dose (0, 5,10,15, and 20 ml/L water) with dipping method in 2 ppm steroid extract of sea cucumber for 18 hours. Each treatment with four replications. The results showed that the highest percentage of males was found in 20 ml/L water dose of 83.75% and the lowest was found in control 55.35%. The presents of honey bee with different doses in 2 ppm steroid extract did not give significantly an effect on percentage of female, individual intersex, survival, and growth of juvenile crayfish. Keywords :freshwater crayfish, honey bee, masculinization, steroid, gamma sea cucumber
