Population justification: Martinez et al. (2006) estimated around 1,600 mature individuals by summing the adults counted in their study of Lake Titicaca in 2003 and those adults counted elsewhere in the Titicaca watershed by Engblom et al. and Rocha et al. 2,583 individuals of all ages were counted on Lake Titicaca itself which combined with smaller numbers elsewhere in the watershed represents a higher population than previously estimated.

Trend justification: The species declined by 15% between 2003 and 2005, consistent with a decline of over 50% in ten years (Asociación Armonia 2007). The greatest current threat to the species, bycatch in fishermen's gill-nets, is continuing.
