Since 200 1, the area and output of Penaeus vannamei cultured in China have been in the forefront of shrimp culture, and its culture amount has reached more than 70% of the shrimp culture amount in China, and it has also become the largest and highest-yielding shrimp species in the world. According to reports, the total annual aquaculture of Litopenaeus vannamei in China is nearly 6.5438+0 million tons, including nearly 200,000 tons of marine aquaculture and 800,000 tons of freshwater aquaculture.
