Doumen Pacific White Shrimp

Doumen Pacific White Shrimp

　　Doumen Pacific White Shrimp (Penaeus Boone), also known as Vannamei shrimp, is domestically translated as Fan Nai Yi shrimp. Commonly referred to as white-legged shrimp, white shrimp, or South American shrimp, it is one of the three most widely farmed shrimp species in the world. Originally from the western coastal waters of the Pacific Ocean in the Americas, it is a euryhaline species that grows rapidly, has a varied diet, and strong environmental adaptability. The larvae hatch in high-salinity seawater, while the adult shrimp grow in brackish water. They reach market size in just 70 days (30 shrimp per 500 grams).

　　Doumen District is located on the western shore of the Pearl River Estuary, with nearly one-third of its area consisting of rivers and shallow seas. It has abundant freshwater and marine resources, and the surface water salinity ranges between 8–20‰, making it highly suitable for Pacific White Shrimp farming. Doumen introduced and successfully trialed the farming of these shrimp in 1998. Currently, the district farms 52,000 tons of Pacific White Shrimp, with Shangheng Town, Baijiao Town, and Liuxiang Town being the main production areas. The product is sold both domestically and internationally. The Pacific White Shrimp has now become a well-known agricultural product of Doumen and is very popular among consumers. It is believed to have health benefits such as nourishing kidneys and strengthening the body, improving digestion and replenishing qi, relieving phlegm, and fighting cancer. It is used to treat conditions such as esophageal cancer, kidney deficiency, nocturnal emission, weak spleen and stomach, qi-deficiency sores, neurasthenia, hand and foot spasms, and postpartum insufficient lactation.

　　Since 2011, numerous food production companies have recognized the large-scale production of Doumen Pacific White Shrimp and have invested in setting up factories here. Fresh Pacific White Shrimp has been transformed into ready-to-eat processed products, which are now sold across the country. By the end of July 2012, six deep-processing enterprises in Doumen District had successfully obtained QS certification. The aquaculture industry in Doumen District is set to further develop in the direction of refined processing and standardized production.
