Mild, sweet and firm, Pacific white shrimp are among the most widely cultivated shellfish in the world. They grow quickly with little maintenance, and may be harvested in as little as 120 days. Two species, Panaeus vannamel and P. stylirostris, are both harvested at sea by trawlers or farmed in ponds. Pond-raised domestic shrimp are typically high in quality due to strict controls and the lack of at-sea time.
