The different concentrations and immersion times of 17α-methyltestosterone
(17MT) on the accumulation in water flea were investigated. Results were found that
amount of 17MT of both groups in each period displayed significantly different (P <0.05)
when compared to the control. The highest accumulation of 17MT was found at the
concentration of 100 mg / L for 420 minutes equal to 0.46 ± 0.10 mg/L. In contrast, it was
found that the amount of 17MT in both concentrations of water at three times was not
statistically significant (P> 0.05)in each treatment. Therefore, results indicated that the
accumulation of 17MT in water fleas can be applied for using accumulated water flea to
produce male tilapia.
