Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. The muskrat, however, is smaller and more tolerant of cold climates, and has a laterally flattened tail it uses to assist in swimming, whereas the tail of a coypu is round. When a nutria is captured, the tail is cut off and turned in to a Coastal Environments Inc. official at an approved site. [13][14][15] Literally, therefore, the name Myocastor means "beaver rat".

McIlhenny who released his entire stock in 1945 on Avery Island. [51], Native to subtropical and temperate South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur ranchers. Its endurance is considered pestilential to human occupation. However, due to escapes and releases from fur farms there are now large feral populations in North America, Europe and Asia. Following a decline in demand for coypu fur, coypu have since become pests in many areas, destroying aquatic vegetation, marshes, and irrigation systems, and chewing through man-made items such as tires and wooden house panelling in Louisiana, eroding river banks, and displacing native animals. Adults are typically 4–9 kg (9–20 lb) in weight, and 40–60 cm (16–24 in) in body length, with a 30 to 45 cm (12 to 18 in) tail. [30], Besides breeding quickly, each coypu consumes large amounts of vegetation. Tatsuzawa, Shirow. [36] The LDWF has determined the wetlands affected by nutria decreased from an estimated 80,000+ acres of Louisiana wetlands in 2002–2003 season to about 6,296 acres during the 2010–2011 season. An eradication was proposed for a small lake in Sicily but opposition by the World Wildlife Fund (WWF) prevented the eradication taking place (Genovesi, 2005).

[61] Each CEI official keeps record of how many tails have been turned in by each individual per parish, the method used in capture of the nutria, and the location of capture. Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Coypu Species Alert. Feral populations of coypu are managed by shooting and trapping. The LDWF has estimated costs for new chemicals to be $300,000 for laboratory, chemistry, and field studies, and $500,000 for a mandatory Environmental Impact Statement. Starting in 2002, the Louisiana Department of Wildlife and Fisheries (LDWF) performed aerial surveys just as they had done for the Nutria Harvest and Wetland Demonstration Program, only it is now under a different program title. This species has been nominated as one of the "100 of the World's Worst" invaders by IUCN. [49], In addition to direct environmental damage, coypus are the host for a nematode parasite (Strongyloides myopotami) that can infect the skin of humans, causing dermatitis similar to strongyloidiasis. 2003).
