Threats [top]

Major Threat(s): The species is threatened by introduction of trout into lakes in the high Andes, by uncontrolled exploitation as a food source, and potentially through the loss of habitat quality due to water pollution.

Conservation Actions [top]

Conservation Actions: Based on its known habitat preferences and distribution, this species occurs in the Reserva Nacional de Junin and may also occur in the Santuario Nacional Huayllay and the Santuario Historico Chacamarca. Measures are urgently required to control and manage the offtake of this species from the wild.
