Many fish of interest in aquaculture, including the dusky grouper, Epinephelus marginatus exhibit reproductive dysfunctions due to confinement, which in turn affect the hypothalamus-pituitary-gonadal axis that controls the reproductive processes in vertebrates. The aim of this study was to evaluate the profile of gonadal steroids and follicle-stimulating hormone (FSH) throughout the reproductive cycle, during the induced spawning and vitellogenesis induction in E. marginatus females in captivity. During the annual cycle, the concentration of androgens did not change. Moreover, the plasma levels of 17β-estradiol (E2) was significantly higher in the end of the period compared with the initial period of confinement. Plasma concentrations of 17...
