Sexual and reproductive patterns of wild Epinephelus marginatus were carefully investigated by means of histological and histochemical analysis, sex steroid profile and demography data. Acquired knowledge was utilized to manage broodstock in captivity. A male broodstock was developed through hormonal sex inversion of juveniles. In captive females, ovarian maturation and ovulation were induced by substained GnRHa treatments. Artificial fertilization trials, embryonic development and first larval rearing trials were described.

Abstract
Sexual and reproductive patterns of wild Epinephelus marginatus were carefully investigated by means of histological and histochemical analysis, sex steroid profile and demography data. Acquired knowledge was utilized to manage broodstock in captivity. A male broodstock was developed through hormonal sex inversion of juveniles. In captive females, ovarian maturation and ovulation were induced by substained GnRHa treatments. Artificial fertilization trials, embryonic development and first larval rearing trials were described.
