Threats

Major Threats
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, these threats are unlikely to have impacted this species greatly.
