Conservation: Herichthys cyanoguttatus is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (LC) least concern (2013). Although H. cyanoguttatus is not considered under any kind of special protection, having a very large distribution range, some of the areas where it is found are subject to several environmental pressures. Rivers in northern Mexico are diverted for irrigation purposes, and exotic species, potentially competitive, like species of Tilapia and Oreochromis, have been widely introduced. An isolated population in the springs at la Mota park in the Ocampo valley in Coahuila state, dried up in recent years due to over exploitation of the water resources, an increasing risk for many populations in this every day more populated and dry area of Mexico.
