Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Characiformes Characidae

Scientific Name: Bryconamericus huilae
Species Authority: Román-Valencia, 2003

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2014-10-08
Assessor(s): Jimenez-Segura, L., Mojica, J., Alonso, J. C., Reis, R. & Lima, F.
Reviewer(s): Tognelli, M.
Facilitator/Compiler(s): Tognelli, M.
Justification:
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 heavily impacted by these threats.
Previously published Red List assessments:
  • 2009 – Least Concern (LC)

Geographic Range [top]

Range Description:This species endemic to Colombia is known from the upper Magdalena River in the Huila and Tolima departments (Maldonado-Ocampo et al. 2005, Maldonado-Ocampo et al. 2008). Its type locality is La Sapayera stream, near the bridge km 2 vía Guadalupe-Florencia, a tributary of La Viciosa stream, Suaza River system, Upper Magdalena, Cachimba trail, Municipality of Guadalupe, Department of Huila, at an elevation of 952 meters (Román-Valencia 2003). It occurs at elevations between 100 and 2,000 m.

Population [top]

Population:There are no data on population size and trends for this species. It appears to be frequent although not abundant.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species usually inhabits high altitude fresh waters. Although it is considered a pool species by Jaramillo-Villa et al. (2010), it has been observed in ravines, streams and river mouths (Maldonado-Ocampo et al. 2005). It has been found living in very clear waters with muddy, stony and sandy bottom, and small backwaters with stony and decomposing vegetation substrate. Males have the highest reproductive activity between January and March (Román-Valencia 2003, Maldonado-Ocampo et al. 2005).
Systems:Freshwater

Use and Trade [top]

Use and Trade: The species is not utilized.

Threats [top]

Major Threat(s): 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). 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 to the species.
