This paper elucidates the developmental changes in the structure of the gonad during sex reversal in the greasy grouper
Epinephelus tauvina (Forsskal). Sex transformation was induced artificially by administering the male hormone
17 α-methyl testosterone to mature female fishes by adding the hormone to the feeding regime. The hormone treated fishes
became mature males after the administration of a mean accumulated dose of 50-55 mg kg-1 body weight of fish, after
9-12 weeks. Sex inversion was induced in both smaller and the larger fish, with no clear relationship with fish size and age.
The study was carried out using histological techniques.
