Resumen
This species has a widespread but disjunct population in the Andean Subregion of southern SouthAmerica. There are 20 subpopulations remaining with gene pools that are 100% Odontesthes hatcheri,mainly in the south-west of the distribution. It has an area of occupancy (AOO) of 80 km 2 . Introgressionby stocking of Odontesthes bonariensis is the primary threat. The 20 subpopulations are grouped into sixdisconnected basins. These six basins represent six locations based on this threat. There has beenobserved continuing decline in the AOO, extent of occurrence (EOO), number of subpopulations, andnumber of mature individuals as a result of this threat. There is also inferred continuing decline inhabitat extent and quality due to urbanisation. Therefore, this species is assessed as Vulnerable.
