This study was conducted to evaluate the effect of aqueous <em>Zingiber officinale</em> extract (ZE) on growth performance, antioxidant activity and resistance of shrimp (<em>Litopenaeus vannamei</em>) challenged with <em>Photobacterium damselae</em> bacteria. A total number of 600 post larvae shrimps (initial weight, 1.06±0.7 g) were randomly distributed into 12 fiberglass tanks representing four treatments each tank containing of 50 shrimp. The control shrimp group (ZE0) was fed a ZE free basal diet. Other groups were fed the basal diet supplemented with 0.5 (ZE 0.5), 1.0 (ZE1) and 1.5 (ZE 1.5) g kg<sup>-1</sup> diet. Diets were offered to shrimp at a feeding rate of 10% of live body weight for 8 weeks. After 8 weeks of experimental trial 30 shrimp from each group was infected with LD70 bacteria<em> P. damselae</em> over 10 days to evaluated disease resistance of infected shrimp. Results revealed that growth performance (WG, SGR, FW and PER), the antioxidant activity (SOD, PO, GPx and CAT) of shrimp have significantly increased and cumulative mortality rate decreased (<em>p</em><0.05) in the ZE1 group compared with the other groups. Meanwhile, the lowest FCR and MDA value were observed in shrimp fed ZE1 supplemented diet. It can be concluded that<em> Z. officinale</em> extract at the level of 1g kg<sup>-1 </sup>(ZE1) diet seems to be the most appropriate level for increasing growth performance, antioxidant activity and disease resistance of <em>L. vannamei</em>.
