Highlights • Sablefish gonadotropin subunit and receptor cDNAs were cloned and sequenced. • Sablefish gonadotropin beta subunits display unique features among vertebrates. • Wild females captured in fall, but not summer, completed gametogenesis. • F1 females exhibit complete inhibition of the gonadotropin-ovary axis. • Captivity may impair vitellogenic growth of ovarian follicles in sablefish.
