Justification
Assessed as Vulnerable due to an inferred population decline of greater than 30% over the past ten years. This is due to water pollution and introduced species but also because of a continuing decline in habitat quality in the Cordoba region.

Threats

Major Threats
A study on the conservation status of the ichthyofauna of Sierras Pampeanas, Cordoba, concluded that A. cordovae had one of the highest conservation priorities (Orlandini et al. 2001). This is largely due to it being endemic to Cordoba; an area which is threatened by alterations in vegetation cover, water pollution and the indiscriminate use of biological resources. The Rio Primero goes through Cordoba City where pollutants enter through mostly untreated effluents. Along the Río Segundo, different industries exist that also pump effluents into the river without treatment (Western Hemisphere Shorebird Reserve Network 2003). Fish species in the region have also been impacted by the introduction of economically important fish species, which compete with the native species for resources such as food and breeding sites (Orlandini et al. 2001).
