Conservation: Vieja breidohri is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (DD) data deficient (2018). Given the very small distribution area of this species, it requires special concern. In recent years the upper Grijalva River has suffered the introduction of many exotic species, many of which are translocations from other areas of southern Mexico (Miller, 2005:360; Gonzáles-Días et al., 2008). It is yet to be seen the extend of the negative effect this will bring in V. breidohri.
