Current status of aquatic non-native species introduced in Uruguay for commercial purposes. For each species we provide information on the status: populations in captivity (CA), individuals registered in the wild (IW), population established in the wild (PW), invasive populations in the wild (IN), and their occurrence in the large hydrographic basins: Rio de la Plata (RP), Rio Negro (RN), Río Santa Lucía (RL), Río Uruguay (RU), Laguna Merín (LM), Océano Atrántico (OA). Additionally, we include details about the purpose of its introduction and the invasive capacity, classified as Potential (PO) based on invasive history, Confirmed (CO) with documented invasions in Uruguay, and Unknown (UN) lacking evidence suggesting invasive potential. Finally we provide the aquaculture score (ranging from 0 to 10) assigned in a national evaluation for aquaculture development (Carnevia 2008; species not evaluated identified with NE), along with literature references.
