Procambarus clarkii, known variously as the red swamp crayfish, Louisiana crawfish or mudbug, [3] is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest.
As early as 2003, Asian farms and fisheries produced more red swamp crayfish (P. clarkii) than the Americas, and this trend accelerated in subsequent years. By 2018, P. clarkii crawfish production in the Americas represented just 4% of total global P. clarkii supply, with Asian production accounting for the rest. [13]
About 70–80% of crayfish produced in Louisiana are Procambarus clarkii (red swamp crawfish), with the remaining 20–30% being Procambarus zonangulus (white river crawfish).

Procambarus is a genus of crayfish in the family Cambaridae, all native to North and Central America. It includes a number of troglobitic species, and the marbled crayfish ( marmorkrebs ), which is parthenogenetic .
A few species, including the invasive Procambarus clarkii and Faxonius rusticus, have been introduced to regions far outside their native range (both in North America and other continents). Conversely, many species have tiny ranges and are seriously threatened; a few are already extinct.

Introduction of the invasive North American signal crayfish (Pacifastacus leniusculus) and red swamp crayfish (Procambarus clarkii): [10] The former is a carrier of crayfish plague, an infectious disease to which it has resistance, while A. pallipes has none.
