Abstract:Reproductive physiology of an anguilliform fish, wild sea conger (Ariosoma meeki) was studied. Spawning season of this species is between July and August, and their oocytes showed synchronous development. mRNA levels of GTH subunits increased in accordance with gonadal development and decreased after spawning. Present results were inconsistent with our previous results in artificially matured Japanese eel.
