Abstract: A total of 691 specimens (114 males, 538 females, and 39 immature specimens) were collected from Bushehr coastal waters of the Persian Gulf from February 2007 to February 2008 to study the reproduction of this species along with its histological gonadal development. Mean absolute and relative fecundity was 263,162 ± 31,046 and 273 ± 27, respectively. The oogonia and oocyte diameter ranged between 6 µm and 875 µm with a mean of 318 µm. The relationship between fecundity and total weight was F = 192.85W + 69,291. Monthly changes in the gonadosomatic index exhibited a higher value in May and October in both sexes (P
