Justification:
Pachypanchax sakaramyi previously was listed as Vulnerable. Improved information since then has resulted in it being uplisted to Critically Endangered.
A visit to Joffreville in 2001 revealed that the upper reaches of the Sakaramy River has been effectively de-watered by diversion of the river’s headwaters, for domestic use by local residents. This last riverine subpopulation of P. sakaramyi exists only as a few fish surviving in puddles fed by the leaking water pipe. This species is reputed to occur in Lac Texier and one other low altitude crater lake, both of which are located inside the boundaries of Montagne d’Ambre National Park. However, these habitats have not been sampled since the late 1950’s and nothing is known of the current status of these populations. In light of these observations this species is assessed as Critically Endangered.
