Conservation: Algansea aphanea is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (EN) endangered (2018). Algansea aphanea currently occupies the San Jeronimo River and the San Pedro Bridge stream, two small tributaries in the upper Coahuayana River drainage. Historical reports suggest that it has been extirpated from the Armeria River drainage, as well as multiple locations in the Coahuayana River drainage. Primary threats include severe flow-modification and surface water diversion for agricultural use, municipal and industrial wastewater discharge, and potential interspecific competition with introduced species (Domínguez Domínguez, 2019).
