Species
All farmed freshwater prawns today belong to the genus Macrobrachium. Until 2000, the only species farmed was the giant river prawn (Macrobrachium rosenbergii, also known as the Malaysian prawn). Since then, China has begun farming the Oriental river prawn (M. nipponense) in large quantities, and India farms a small amount of monsoon river prawn (M. malcolmsonii). In 2003, these three species accounted for all farmed freshwater prawns, about two-thirds M. rosenbergii and one-third M. nipponense.
About 200 species in the genus Macrobrachium live in the tropical and subtropical climates on all continents except Europe and Antarctica.

Famous quotes containing the word species:
“An unjust law is itself a species of violence. Arrest for its breach is more so.”
—Mohandas K. Gandhi (1869–1948)
“Genius detects through the fly, through the caterpillar, through the grub, through the egg, the constant individual; through countless individuals the fixed species; through many species the genus; through all genera the steadfast type; through all the kingdoms of organized life the eternal unity. Nature is a mutable cloud which is always and never the same.”
—Ralph Waldo Emerson (1803–1882)
“There are acacias, a graceful species amusingly devitalized by sentimentality, this kind drooping its leaves with the grace of a young widow bowed in controllable grief, this one obscuring them with a smooth silver as of placid tears. They please, like the minor French novelists of the eighteenth century, by suggesting a universe in which nothing cuts deep.”
—Rebecca West (1892–1983)
