abstract (from publication):
The aim of this study is to survey the fish fauna of the Iguazu National Park and designate those vulnerable species with special value (EVVES). As a result of this project 104 species were recorded, of which 28 are endemic to the basin and 13 represent new records for Argentina. Finally, 87 species of PNI with special value representing 83% of total fish recorded were identified.
