Sex Reversal of Tilapia: 17α-Methyltestosterone Dose Rate by Environment and Efficacy of Bull Testes
Sex reversal of newly hatched tilapia generally is accomplished via oral administration of 17α-methyltestosterone (MT), which has been incorporated into a starter fish feed at 60 mg MT/kg feed (Popma and Green, 1990). Although the use of the 60 mg MT/kg feed dose consistently yields populations comprised of less than 5% females (i.e., > 95% males), this has not been shown to be the optimal dose...
متن کاملMasculinization of Nile Tilapia (Oreochromis niloticus) through Immersion in 17α- Methyltestosterone or 17α-Methyldihydrotestosterone
One of the most common techniques for producing mono-sex populations is steroid-induced sex inversion. This involves the administration of synthetic androgens (to produce male populations) or estrogens (to produce female populations). Several methods of steroid administration are possible, including injection, microencapsulation, feeding of steroid, and immersion of fry in steroid solutions. Th...
