Worldwide Distribution, Spread of, and Efforts to Eradicate the Nutria (Myocastor coypus)

East Asia

East Asia Nutria Map Japan South Korea China Thailand Russia Russia China: Introduced into China in the early 1960s for fur farming. There are no reports of escapes into the wild ( Xie, written commun., 1999). Nutria are also being exported from China to other countries for fur farming (Kanwanich, 1998).

Introduced into Japan in 1910 (Miura, 1976). The Japanese military encouraged breeding of nutria on small fur farms because of the high quality of nutria pelts (Miura, 1976). When the pelt price dropped, the nutria were either killed or released (Miura, 1976). Since 1963, nutria have been hunted as an eradication/control method (Miura, 1976). Japan’s largest concentration of nutria occur in the Okayama prefecture (Miura, 1976).

South Korea
: Nutria have been documented in South Korea in Han and others (1999). The date of introduction and present status are unknown.

The government of Thailand views nutria as a problem (Kanwanich, 1998). Nutria imported from China in 1993 for breeding and by 1998 were seen in the wild (Kanwanich, 1998). Some have been eaten by the local population, but no organized control program has been implemented (Kanwanich, 1998). The government prohibited importing additional animals into the country (Kanwanich, 1998).
