To study on fecundity of O. ruber, in spawning season, 31 samples caught in Khouzestan waters on Feb. 1996 to April 1997 were examined, and gravimetry method was used. Maximum absolute fecundity were 1483369 ± 14409 and 81726± 1831 eggs respectively, and relative fecundity 1107 ± 10.6 and 256±5.5 per gram body weight, respectively. The highest correlation coelficient was observed in absolute fecundity with gonadal weight (G W) and relative fecundity with gonado somatic index (GSI). Also absolute and relative fecundity had the highest multiple regression coefficient with gonado somatic indec (GSI), gutted weight (GU) and standard length (SL).
