Conservation: Allodontichthys tamazulae is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (VU) vulnerable (2018). Pollution from a sugar cane mill near the town of Tamazula has made a portion of the former range of the species in the lower Tamazula River uninhabitable since the 1970s (Lyons et al., 2000). Additional pollution from waste water from the town of Tuxpán, and from sewage from a huge paper mill in Atenquique, wash-in of fertilizers and pesticides from ubiquitous sugar cane fields, in addition to sediment as a result of almost entire deforestation in the headwaters of the Río Atenquique (and other affluents of the Río Tuxpán), along with the Río Tuxpán itself for paper production leads to an ongoing decline in extent of occurrence, area of occupancy and quality of habitats (Köck, 2020). Recent surveys have encountered A. tamazulae at ten locations, several of which had moderately large numbers of fish, and populations appear to be stable (Lyons et al., 2019:125).
