This study aims to investigate the reproductive cycle of striped piggy (Pomadasys stridens) along the northern coasts ofthe Persian Gulf (Bushehr Province, Iran) from October 2014 to September 2015. A total of 276 specimens were collected ona monthly basis and their length, weight, sex, gonad weight, and maturity status were recorded. The mean monthly values ofGSI indicated that the main spawning period occurs during December to June. Based on ovarian histology and macroscopicanalysis of gonads five stage of maturity development were identified. The result of present study demonstrated that, similarto several other tropical species with a distinct annual reproductive cycle, P. stridens characterized by prolong spawningseason and females are the predominant sex in the population. The percentage frequency of different developmental oocytestages within oocyte cluster verifies that the P. stridens is a batch spawner with asynchronous oocyte development.
