In 1990, the world’s shrimp production was estimated at 633,000 tons, the highest record in history, an increase of 12% over 1989; the production value of shrimp farming has reached billions of U.S. dollars and the output value of shrimp farming in China, Indonesia, Thailand and Ecuador alone Up to 3 to 600 million U.S. dollars. Currently, the world’s total shrimp market is 2.6 million tons, of which 25% is aquaculture shrimp, accounting for 50% of the 3 million tons of shrimp required by the world market in 2000 at the current rate of development. In shrimp farming countries and regions reached more than 40, breeding area of more than 1 million hectares. In the eastern hemisphere, shrimp farming is more developed with 16,565 shrimp farms, a total of 893,500 ha of aquaculture water, 3300 nursery grounds and a head-to-shrimp production of 535,000 tons, accounting for 84.5% of the total shrimp production in the world, mainly in China and Southeast Asia ; 1800 shrimp farms in the western hemisphere, 129,400 hectares of aquaculture water, 133 nursery grounds,
