Abstract: Induction of ovarian maturation in Penaeus vannamei, by injection of brain extract prepared from female lobster, Homarus americanus, with developing ovaries was investigated under tank culture conditions. Five of eight females with brain extract injection were maturing while only two of eighteen females of the control groups with abdominal ganglion or saline injection matured. Two females at stage V were found 17 days after injection of the lobster's brain extract. This indicates that ovarian maturation of P. vannamei in tanks can be induced and accelerated by injection of brain extract prepared from maturing females of another species. Ovarian maturation may be induced by a brain hormone which stimulates the releasing of a gonad-stimulating hormone from the thoracic ganglion. Therefore, a gonad-stimulating hormone-releasing hormone (GSH-RH) is nominated as a possible hormone type in the brain responsible for ovarian maturation in the shrimp.
