White Vannamei Prawns

Found both in the wild and farmed. The traditional methods of farming are very harsh on the environment and we dont recommend them as sustainable at all. We do recommend the farmed Vannamei Prawns out of good farms, currently only Belize Prawns are Ocean wise and sustainable. They are farmed in close containment systems without chemicals. We carry them so ask for them at our stores or ask our reps about them.

Whiteleg shrimp (Litopenaeus vannamei, formerly Penaeus vannamei), also known as Pacific white shrimp or King prawn, is a variety of prawn of the eastern Pacific Ocean commonly caught or farmed for food.


L. vannamei grows to a maximum length of 230 mm (9.1 in), with a carapace length of 90 mm (3.5 in).[2] Adults live in the ocean, at depths to 72 m (236 ft), while juveniles live in estuaries.[2] The rostrum is moderately long, with 7–10 teeth on the dorsal side and two to four teeth on the ventral side.[2]

Distribution and habitat

Whiteleg shrimp are native to the eastern Pacific Ocean, from the Mexican state of Sonora to as far south as northern Peru.[2] It is restricted to areas where the water temperatures remain above 20 °C (68 °F) throughout the year.[3]

Fishery and aquaculture

During the 20th century, L. vannamei was an important species for Mexican inshore fishermen, as well as for trawlers further offshore.[2] In the late 20th century, the wild fishery was overtaken by the development of aquaculture production; this began in 1973 in Florida using prawns captured in Panama, that were used in hatcheries for larvae production.[3]

In Latin America, the culture of L. vannamei started to develop with the availability of hatchery larvaes, the development of feeds, the technification of the growth processes, the freezing installations and market channels, among others.

From Mexico to Peru most countries developed in the 70s and 80s large production areas. Ecuador became one of the world leaders producers of this type of shrimp.

Around the beginning of the millennial, Asia introduced this species in their aquaculture operations (Changing from penaeus monodon). China, Vietnam, India and others have become mayor packers as well.

The packing of shrimp from aquaculture origin has overpassed the quantity of ocean caught wild shrimp in recent years. Both origins, ocean caught and aquatulture, are subject to weather changes and diseases.

By 2004, global production of L. vannamei approached 1,116,000 t, and exceeded that of Penaeus monodon.[3]

Weather effect

Normally, there are peaks of production during the warm El Niño years, and reduced production during the cooler La Niña years. The effect is on ocean caught as well as on aquaculture origin.


There are several known diseases.[3] Production of L. vannamei is limited by its susceptibility to white spot syndrome, Taura syndrome, infectious hypodermal and haematopoietic necrosis, baculoviral midgut gland necrosis, and Vibrio infections.[3] So far, none of the identified diseases have any impact of human health.

Impact on Nature

In 2010, Greenpeace International added the whiteleg shrimp to its seafood red list. This lists fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries.[4] The reasons given by Greenpeace were "destruction of vast areas of mangroves in several countries, overfishing of juvenile shrimp from the wild to supply shrimp farms, and significant human rights abuses".[4] Whiteleg shrimp, Penaeus vannamei, production was 53% of the total production of farmed crustaceans in 2016 globally.[5]

As in many industries, entities that certify different aspects of the shrimp operations developed to make sure issues like sustainability, fair trade, social responsibility, and others were properly managed. Responsible producers, traders, and marketplaces adopt this certifications in order to differentiate themselves.
