822-829Based on histological, microscopic and macroscopic observations, the highest gonadosomatic index (GSI) value for both sexes of Chrysaora sp. was found to be in July. Female GSI value of Chrysaora sp. was higher than male. Furthermore, this species showed an asynchronous pattern of reproduction. Spawning and the peak of the reproductive seasons were in July. Maturation in Chrysaora consisted of four stages (pre vitellogenic, early vitellogenic, mid vitellogenic and late vitellogenic) in female and three stages (spermatogonia, spermatocytes, and spermatids) in male
