Abstract
Groupers (Family Serranidae) are protogynous hermaphrodites. Natural sex inversion of different species occurs at 2-11 years of age . The scarcity of wild mature males and the length of time to change sex underline the need to do induced sex inversion studies. In Epinephelus tauvina and E. fario, sex inversion was successfully induced by oral administration of 17 alpha-methyltestosterone (MT). This paper reports on the induction of sex inversion of juvenile grouper E. malabaricus using bi-weekly intramuscular injections of MT.
