On the presence of the giant freshwater prawn, Macrobrachium rosenbergii, in French Guiana confirmed by citizen science and genetic analyses

Résumé

We report for the first time the presence of self-sustaining populations of Macrobrachium rosenbergii in French Guiana. Genetic analyses of the cytochrome c oxidase subunit I marker (COI) confirmed the identity of the species as well as historical records about the introduction of the species from commercial stocks. Despite the limited presence of Macrobrachium rosenbergii in French Guiana, the species is recorded in several river basins, including two where the species has never been farmed. This suggests that the species is able to disperse locally and highlights its potential invasive nature in the territory.
