Identification: Description taken from Perez Farfante and Kensley (1997). The rostrum moderately long, surpassing antennular peduncle in young, reaching about midlength of second antennular segment in adults. Rostrum armed with dorsal and ventral teeth, ventral teeth usually 2-4 but occasionally 5-8. Antennal and hepatic spines of carapace pronounced, orbital and pterygostomian spines absent. Postocular sulcus absent, postrostral carina of variable length, sometimes almost reaching posterior margin of carapace. Longitudinal and transverse sutures absent. Sixth abdominal somite with three cicatrices (longitudinally disposed ridges). Telson unarmed. Mature males with symmetrical, semi-open petasma, not hooded; lacking distomedian projections; ventral costae short, not reaching distal margin and distinctly gaping. Mature female with open thelycum and sternite XIV bearing ridges, prominences, depressions, or grooves.
Size: Grows to about 230 mm in length (Dore and Frimodt 1987).
Native Range: Found in the eastern Pacific from Sonora, Mexico to Tumbes in northern Peru (Perez Farfante and Kensley 1997).

Aquaculture of the Pacific white shrimp in the United States began with the studies of Parker et al. (1974) who reared the shrimp in a pond system in Texas and in Florida with the successful hatching and pond culture of L. vannamei in Crystal River in 1972. In 1985, Litopenaeus vannamei postlarvae were imported from Panama to the Waddell Center in South Carolina to develop intensive culture techniques for this species in earthen ponds (Sandifer et al. 1988). Escapes of cultured shrimp to the wild have occurred in both Texas (Balboa et al. 1991, Howells 2001, ) and South Carolina (Wenner and Knott 1992).
Discussion of the history of introductions is taken from Briggs et el. (2004). Litopenaeus vannamei, native to the Western Pacific Coast of Latin America, was introduced to Tahiti in the early 1970s for research on their potential for aquaculture. Subsequent development of intensive breeding and rearing techniques led to their transport to Hawaii, the north-west Pacific coast, the eastern Atlantic coast (South Carolina), Gulf of Mexico (Texas), Belize, Nicaragua, Colombia, Venezuela, and Brazil in the late 1970s and early1980s. White shrimp were introduced into Asia for experimental purposes in 1978-79 and for commercial activities in the 1990s. First introductions to Asian countries are as follows: Mainland China, 1988; Taiwan, 1995; Viet Nam, 2000; Indonesia, 2001; Thailand, 1998; Malaysia, 2001; India, 2001, Philippines, 1997; Pacific Islands, 1972.

Means of Introduction: Introductions to date are the result of accidental aquaculture releases.
Status: Although collected periodically in commercial shrimp trawls, there is currently no evidence that populations have established themselves in the wild (Howells 2001, South Carolina Wildlife and Marine Resources Department).
Impact of Introduction: Exotic shrimp viruses associated with L. vannamei may pose a risk to Gulf of Mexico and southeastern U.S. Atlantic penaeid shrimp fisheries. Other crustacean fisheries may also be at risk from introduced viruses. The Taura Syndrome Virus (TSV) is a virulent disease of L. vannamei in culture and has been documented in wild populations in the fisheries of Ecuador, El Salvador, and southern Mexico near the border with Guatemala (Lightner 1996). The white spot virus (WSSV) has been confirmed in wild shrimp populations in the Gulf of Mexico and there is the possibility that TSV also exists (Jeff Lotz, personal communication). A shrimp-farm outbreak of "IHHN" virus on the Pacific coast of Mexico may have been responsible for depression of wild shrimp populations (JSA 1997).
