The spawning periodicity of silver pomfret, Pampus argenteus, was investigated in 627 specimens (137 female and 490 male) collected monthly by trawl net from the Northwest the Persian Gulf for a one year period (March 2004 to February 2005). Seven maturity stages were recognized by Kesteven scale. The length at first maturity (LM50) was calculated as 192 mm in combined sex. The overall sex ratio (female: male) was 1:3. Fluctuations in the Gonadosomatic Index (GSI) values and percentage of mature specimens suggested prolonged spawning season from May to October. There were two spawning peaks, the first one between May and July and the second in October. It is concluded that Iranian waters (in Khuzestan province)are the main spawning and nursery grounds for silver pomfret in the Persian Gulf.
对627尾银鲳（Pampus argenteus）样本（137尾雌鱼和490尾雄鱼）的产卵周期进行了研究，这些样本于2004年3月至2005年2月期间，每月通过拖网从波斯湾西北部采集，为期一年。根据凯斯蒂文（Kesteven）标准识别出七个成熟阶段。雌雄合并计算的初次性成熟体长（LM50）为192毫米。总体性别比（雌：雄）为1:3。性腺指数（GSI）值和成熟样本百分比的波动表明，产卵季节从5月延长至10月。有两个产卵高峰，第一个在5月至7月之间，第二个在10月。得出的结论是，伊朗水域（胡齐斯坦省）是波斯湾银鲳的主要产卵和育幼场。
