Conservation: Hybopsis calientis is evaluated by the international union for the conservation of nature in the iucn red list of threatened species as (CR) critically endangered (2018). By 2011, Hybopsis calientis had disappeared from most of the sites where it had been recorded historically, representing a population reduction of approximately 82%. The primary threat to Hybopsis calientis is habitat degradation as a result of urban, industrial, and agricultural pollution, as well as habitat fragmentation resulting from damming throughout its range. The establishment and spread of invasive species and their parasites (e.g. Cyprinus carpio and Micropterus salmoides) likely have an impact on the abundance of H. calientis (Domínguez Domínguez, 2019).
