Abstract
The objectives of this study aimed to evaluate the relationships between the brood stocks age and sizes ( weight and length) and the first fish maturation for both males and females of gilthead sea bream , Sparus aurata (L,),
Five hundred juveniles sea bream(3month age) with average weight 4.6 g and length 5.9 cm were used in the present study through the period 2001 to 2004 (3years). 
It could be concluded that the complete sexual maturity of male and female occurred at 36month of age . The first maturation in females was recorded at 15 months of age, at weight 267.8g, length 22.4cm, and percentage 0.96 % of the tested sample, while in males was recorded at 12 months with a ratio of 13 % of the tested sample, weight was 73.4- 92.2gand length was 14.9-16.2 cm. The complete sexual maturity of female occurred at 36 months of age at body weight ranging from 461.9 to 934.6g and, which the total length was 30.3-42.4cm,but in males at the same age and average body weights ranging from 340 to 669.4 g with length 29.5-34.6cm. The sea bream male and female fish reached 100% maturation with a sex ratio 1:1.38 for female and male, respectively.
