“…In South America, P. clarkii (Girard 1852), Macrobrachium amazonicum (Heller 1861), M. jelskii (Miers 1878), M. rosenbergii (De Man 1879), and D. pagei (Stimpson 1861), are five important freshwater decapods with a strong invasive potential. Procambarus clarkii and M. rosenbergii are native to North America and Asia, respectively, and were introduced in South America for commercial purposes, while M. amazonicum, M. jelskii and D. pagei are native to the Amazon region, but can be considered transplants in other regions of South America, because their introductions were provided by anthropogenic actions [20].…”
