Hormonal and Environmental Control of Puberty in Perciform Fish

A specific chronology for puberty and changes at the brain–pituitary–gonad axis for sea bass are reviewed. Recent findings demonstrate that the Kisspeptin system, gonadotropin releasing hormones, follicle stimulating hormone, 11‐ketotestosterone, and leptin are potential candidates for the onset of puberty of this fish species, stressing the importance of the daily and annual rhythms of some of these hormones. Environmental control of puberty is also reviewed, specifically the manipulations of constant photoperiods for altering or even suppressing the onset of puberty in sea bass. Recently, a possible narrow sensitive period for suppressing gonadogenesis in sea bass has been identified.
