Two studies were conducted to evaluate growth performance, feed utilization, survival rate and the economic cost of white shrimp (P. vannamei) in Suez Canal region. The first study was conducted in Eldebba farm in western region of Port Said Governorate in collaboration with a private fish farm. The second study was conducted in Suez Canal Fish Farm. The pond was stocked with white shrimp (P. vannamei) at the rate of 70000 PL 26 / feddan in eldebba Farm. In Suez Canal Farm the ponds stocked with 150000 PL 26 / feddan white shrimp (P. vannamei) with average initial 0.002 g in both Farms. A good quality (38 % protein) commercial feed was provided. Growth performance, feed utilization, survival rate and comical evaluation were the best in Eldebba farm than Suez Canal farm. It could be concluded that stocking white shrimp at density 70000 / feddan was the best in terms of growth performance, feed utilization, survival and economic evaluation under this experimental conditions.
