AB  - The effects of 17 &#946;-estradiol were investigated on survival, feminization and growth of green tiger shrimp, <I>Penaeus semisulcatus</I> in different life stages. Egg, nauplius, protozoea, mysis and postlarvae were immersed in water containing 50 &#956;g L<SUP>-1</SUP> 17 &#946;-estradiol from the beginning of the each stage to the end of the stage. The grow out were carried out about 4 months to emerging the secondary sexual characters in ventral side of shrimp in this ponds. The results of the experiment showed that the method of immersion 50 &#956;g L<SUP>-1</SUP> 17 &#946;-estradiol in eggs, nauplius, protozoea stages decreases the survival rate. The best feminization rate (71.88%) were observed in naupli group and this result was important statistically than control and other groups (p&lt;0.001). Respect of the growth rate, the highest mean weight was 14.15&plusmn;2.41 g in nauplii group and this followed by control (13.66&plusmn;2.48 g) and egg groups (12.04&plusmn;0.68 g) and were significantly different from the other groups (p&lt;0.05).
