Penaeus monodon, commonly known as thegiant tiger prawn,[1][2]Asian tiger shrimp,[3][4]black tiger shrimp,[5][6] and other names, is a marinecrustacean that is widely reared for food.
Females can reach about 33 cm (13 in) long, but are typically 25–30 cm (10–12 in) long and weigh 200–320 g (7–11 oz); males are slightly smaller at 20–25 cm (8–10 in) long and weighing 100–170 g (3.5–6.0 oz).[1] The carapace and abdomen are transversely banded with alternative red and white. The antennae are grayish brown. Brown pereiopods and pleopods are present with fringing setae in red.[8]
The first occurrence ofP. monodon in the U.S. was in November 1988. Close to 300 shrimp were captured off the Southeastern shore after an accidental release from an aquaculture facility. This species can now be caught in waters from Texas to North Carolina. AlthoughP. monodon has been an invasive species for many years, it has yet to grow large, established populations.[11] Escapes in other parts of the world, though, have led to establishedP. monodon populations, such as off West Africa, Brazil, and the Caribbean.[12][13]
P. monodon is suited to inhabit a multitude of environments.[14] They mainly occur in Southeastern Asia, but are widely found.[14] Juveniles ofP. monodon are generally found in sandy estuaries and mangroves, and upon adulthood, they move to deeper waters (0– 110 m) and live on muddy or rocky bottoms.[15] TheP. monodon has shown to be nocturnal in the wild, burrowing into substrate during the day, and coming out at night to feed.[16]P. monodon typically feed ondetritus,polychaete worms,mollusks, and small crustaceans.[16][17] They feed on algae, as well. Due to their nutrient-rich diet, these shrimp are unable to consume phytoplankton because of their feeding appendages, but they are able to consume senescent phytoplankton.[18] They also commence mating at night, and can produce around 800,000 eggs.[14]

P. monodon is the second-most widely cultured prawn species in the world, after onlywhiteleg shrimp,Litopenaeus vannamei. In 2009, 770,000tonnes were produced, with a total value ofUS$3,650,000,000.[1]P. monodon makes up nearly 50% of cultured shrimp alone.[20]
The prawn is popular to culture because of its tolerance to salinity and very quick growth rate,[11] but they are very vulnerable to fungal, viral, and bacterial infections.[21] Diseases such aswhite spot disease andyellowhead disease have led to a great economic impact in shrimp industries around the globe.[22] They can receive transmitted diseases from other crustaceans such as theAustralian red claw crayfish (Cherax quadricarinatus), which is susceptible to yellowhead disease and has shown to transmit it toP. monodon in Thailand.[23]
Black tiger shrimp's susceptibility to many diseases engenders economic constraints towards the black tiger shrimp food industry in Australia, which is farm-raised. To confront such challenges, attempts have been made to selectively breed specific pathogen-resistant lines of the species.[24]
P. monodon has been farmed throughout the world, including West Africa, Hawaii, Tahiti, and England.[12] For optimal growth,P. monodon is raised in waters between 28 and 33 °C. Characteristically for thePenaeus genus,P. monodon has a natural ability to survive and grow in a wide range of salinity, though its optimal salinity is around 15-25 g/L.[25] While in a farm setting, the shrimp are typically fed a compound diet, which is produced in dried pellets.[17] By mixing the diet to have compound feeds and fresh feed,P. monodon was shown to have better reproductive performance.[17]
In 2010,Greenpeace addedP. monodon to its seafood red list – "a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries". The reasons given by Greenpeace were "destruction of vast areas of mangroves in several countries, overfishing of juvenile shrimp from the wild to supply farms, and significant human-rights abuses".[26]
In an effort to understand whetherDNA repair processes can protectcrustaceans against infection, basic research was conducted to elucidate the repair mechanisms used byP. monodon.[27] Repair of DNA double-strand breaks was found to be predominantly carried out by accuratehomologous recombinational repair. Another, less accurate process,microhomology-mediated end joining, is also used to repair such breaks.
