IUCN Red List

Listed as Least Concern on the basis that this species is known from a relatively wide, remote area where its population status and threats remain poorly-known but are thought to be localised. Although multiple large dam construction projects have been proposed for the Salween, a moratorium was in place as of 2012 and a decade later there are no dams on the main stream and none is known to be present, at present, (IUCN 2023).
