IUCN Red List

Auchenipterus demerarae has a wide range of distribution and it is known from the Demerara River, Essequibo River and its tributaries, the Rupununi River in Guyana, and the Botanamo River of the Rio Cuyuni system in Venezuela. The extent of occurrence (EOO) is estimated at 104,392 km2 and the area of occupancy (AOO) at 11,128 km2. The overall area of the distribution seems relatively well preserved, despite local impacts of mining activities in Cuyuni River, but there are no apparent risks to the species. Thus, Auchenipterus demerarae is assessed as Least Concern (LC) due to its wide distribution and the lack of any known major threats (IUCN 2022).
