Cenrophorus uyato .

TL ranged between 47 and 90 cm for males and between 50 and 100 cm for females. Common TL ranged from 70 to 80 cm for males and from 75 to 80 cm for females. This species was recorded in all months of year except January. Females constituted 53.4% of species catches. Its caught appeared no significant difference between seasons (X 2 = 13.448, P = 0.004), peak of season landing was in summer ( Fig. 2g ), while a peak of juveniles landing was in spring ( Fig. 3g ). Males and females of C. uyato off Syrian marine warts matured at 79.2 cm and 86.7 cm TL [ 17], respectively. Therefore, about 62% of males and 66% of females were immature ( Fig. 4g ).
