The effects of gonadotropin-releasing hormone agonist (GnRHa) on plasma levels of follicle-stimulating hormone (Fsh) and luteinising hormone (Lh) are reported for female greater amberjack Seriola dumerili with post-vitellogenic ovarian oocytes. Five females were implanted with pellets containing GnRHa (600 μg kg-1 body weight), while five other females were injected with saline. All females implanted with GnRHa-containing pellets ovulated 36-42 h post-implantation. The GnRHa implants elevated Lh, but not Fsh plasma levels within 42 h of GnRHa administration.
