|Scientific Name:||Bryconamericus huilae|
|Species Authority:||Román-Valencia, 2003|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Reis, R & Lima, F.|
|Reviewer(s):||Collen, B., Darwall, W., Ram, M. & Smith, K. (SRLI Freshwater Fish Evaluation Workshop)|
The species is assessed as least concern due to wide distribution and lack of major threats across its range. While the river basin is highly impacted in the lower reaches, the species occurs at higher altitudes, and therefore is not impacted heavily by these threats.
|Range Description:||This species is known from the upper Magdalena River, Colombia.|

|Population:||No population information known.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||B. huilae is a benthopelagic (ecological region at the lowest level of water body) species that generally inhabits high altitude freshwaters.|
It is likely that B. huilae is threatened by habitat degradation. The Magdalena River basin has a high human population, of about 32 million, which results in major threats such as reservoir construction, interrupting longitudinal connectivity and leading to river floodplain degradation, and large scale agro-industrial projects in the catchment that leads to accelerated aquatic habitat degradation because of increased soil erosion and pesticide input. In addition, large amounts of untreated sewage is emptied into the basins waterways (Junk 2005). Though B. huilae is not known to be harvested, it is interesting to note that catches in the Magdalena River have declined by 78% over the past two decades, (Harvey 1998). It is not clear whether this is due to over-fishing, habitat degradation or both, but it is likely to have implications for other species in the Magdalena River basin.
However, as this species inhabits the upper reaches, and the threats are most severe in the lower basin near the river mouth, these are unlikely to constitute serious threats.
