Ochrona: Chirostoma jordani jest wpisany prez Międzynarodową Unię Ochrony Przyrody na Czerwoną Listę Zagrożonych Gatunków IUCN jako (LC) Najmniejszej troski (2018). The species is widespread and while it is possibly declining in parts of its range, it is not thought that any global population decline is likely. Chirostoma jordani is however threatened by habitat degradation in part of its range. A study of the Rio Lerma drainage concluded that the basin has experienced a staggering amount of degradation during the 20th century (Soto Galera, 2019).
