The present study aimed to investigate the reproductive biology and ovarian histology of female Greater lizardfish, Saurida tumbil (Family: Synodontidae) in the Iranian coast of the Persian Gulf (Bushehr province), from February 2007 to February 2008, conducted by regular monthly collections. The total length of females ranged from 26.1 to 58 cm and the weight ranged from 136 to 1550 g. Observations on the seasonal distribution of maturity stages and variations in seasonal fluctuations in the gonadosomatic index (GSI) confirmed recent findings that the spawning periods have two peaks, the first and the maximum was in May and the second and smaller peak was in October. It was found that female Saurida tumbil reach the first sexual maturity at 27 cm. Mean absolute and relative fecundity were 263162 and 273, respectively. The minimum and maximum ova diameter was 6.71µ (stage 1) and 875.34µ (stage 5). The curvilinear relationship between the fecundity and total weight of the fish was F=2657.8 W 0.6617. The mean of the sex ratio was 1:5 (M:F( This sex ratio was congruent with other studies. HSI and GSI fluctuations in females were similar.
