Involvement of pituitary gonadotropins, gonadal steroids and breeding season in sex change of protogynous dusky grouper, Epinephelus marginatus (Teleostei: Serranidae), induced by a non-steroidal aromatase inhibitor

Highlights • Letrozole (100 mg/kg) induced the sex change in protogynous dusky grouper in 9 weeks. • 11KT modulated the beginning and T the final phase of the sex change. • LH and FSH were modulators of the sex change by aromatase inhibitor. • Sex change is more effective during the peak of the bree...
