The reproductive biology of 500 specimens of Liza carinata (Family: Mugilidae) collected from catches by gill and trammel nets on Bitter Lakes (Suez Canal, Egypt) was studied. There were monthly variations in sex ratio between females (287 fish = 57.4%) and males (213 fish = 42.6%). Sex ratio was (1: 1.35) for males to females respectively. The length at 50% maturity was 13.5 cm for females and 13.2 cm for males. The breeding season extends from September to January. Oocyte diameters increase from September (388 ± 15.8 µm), until January (569 ±24.8 µm). The absolute fecundity ranged was from 64009 to 117428 for fish with the total length ranging from 12.5 to 18.4 cm, whereas relative fecundity ranged from 4954 to 6546/cm.
