Common name: Asian tiger shrimp
available through www.itis.gov
Identification: Mature tiger shrimp caught in the wild can be distinguished from native American penaeid shrimp by their overall rusty brown color and the distinctive black and white banding across their back and on their tail. There is also a rarely seen color variant of the species with a conspicuous, wide, reddish-orange stripe along its back.
Size: up to 30 cm and 320 g (females larger than males of same age)
Native Range: Indo-West Pacific oceans including East Africa, South Asia, Southeast Asia, the Philippines, and Australia (FAO 2011; McCann et al. 1996).

Nearly 300 tiger shrimp were collected off the coasts of South Carolina, Georgia and Florida in the three months after the August, 1988 accidental release of roughly 2,000 animals from an aquaculture facility in South Carolina. In September 2006, 18 years later, a single adult male was captured by a commercial shrimp fisherman in Mississippi Sound near Dauphin Island, Alabama (L. Hartman, pers. comm.). A month later, five specimens were collected in Pamlico Sound, North Carolina (T. Moore, pers. comm.). A single specimen was caught in in August, 2007 in Vermilion Bay, Louisiana (H. Blanchet, pers. comm.), and several more were reported from Florida and both Carolinas shortly thereafter. The first documented collections in Georgia, Mississippi and Texas occurred in 2008, 2009 and 2011, respectively. The species has now been found from North Carolina to Texas. Although the number of reports is high (314 from 2006-2011), the number of individuals ranges from 1-15 and averages just slightly greater than one specimen per report. Penaeus monodon was one of six species of penaeid shrimp transported to Hawaii for aquaculture and research between 1978-1991. Some individuals escaped from culture ponds during flooding, but no populations are thought to be established (Eldredge 1994).
Ecology: In their native range, tiger shrimp mature and breed in tropical marine habitats. Larvae, juveniles and sub-adults occupy shallow coastal estuaries, lagoons, and mangrove areas. Sub-adults subsequently move offshore, where they mature and breed, living on sand or muddy-sand bottom in up to 110 m water depth (Holthuis 1980). Temperature is an important environmental variable that influences not only the success of P. monodon culture, but also the survival and dispersal of wild P. monodon in areas where it is introduced. Survival and growth are optimal at temperatures between 28°C and 33°C, but growth is unlikely below 20°C (Lumare et al. 1993). Lethal extremes are not definitively known, although mortality has been reported at temperatures <13°C and >33°C (Jintoni unpublished). A rapid growth rate and broad tolerance to salinity (2-30‰, FAO 2011) have contributed to the success of this species in aquaculture. However, these are also characteristics that enable it to invade new areas.
Means of Introduction: Although production has declined over the past decade, during the 1970s and 80s global production of farmed Penaeus monodon exceeded all other shrimp species. Tiger shrimp were widely farmed outside of their native range where conditions were suitable, including West Africa and various locations throughout the Caribbean. In the US, the last attempt to culture tiger shrimp occurred in Florida in 2004 (Salisbury 2004); however, a successful harvest was not achieved there (Knott pers. comm.). Peer-reviewed documentation does not exist, but it is believed that wild populations have become established along the coasts of West Africa from Senegal to northern Angola, in South America from Guyana to Colombia, and off the Dominican Republic in the Caribbean (Knott pers. comm.). Introductions of tiger shrimp into the southeastern US are most likely explained by escapement from aquaculture facilities following flooding by storms and hurricanes, or through migration from areas where tiger shrimp have previously become established in the wild. Although they are less probable, other pathways of introduction (e.g. ballast water discharge) are also possible.hurricanes.
Status: Although the annual numbers of reported tiger shrimp may reflect, to some degree, a greater effort to document their occurrence, they also suggest that there has been an actual increase in abundance along the southeastern US coast over the past five years. Six individuals were collected in 2006, four in 2007, 21 in 2008, 47 in 2009, 32 in 2010 (Knott pers. comm. and NAS records), and 591 in 2011 (with 257 in North Carolina alone - K. Hart, personal communication). Considering this increase, it is likely that a breeding population may be present.
Impact of Introduction: Currently, the impacts of this invasive shrimp on the native fauna in areas where it has been introduced are uncertain. The black tiger shrimp, however, is a more aggressive predator on soft-bodied invertebrate benthic organisms than native shrimp, feeding primarily on small crabs, shrimp, bivalves and gastropods (Marte 1980). In addition to potential predation of P. monodon on native shrimp species, this non-native shrimp may also have an advantage over them in competing for food resources. Tiger shrimp are also susceptible to a variety of viral diseases and are capable of transmitting them to native shrimp and other crustaceans. The likelihood of this happening in wild populations, however, remains unknown.
