    Chirostoma: Brief Summary
    provided by wikipedia

    Chirostoma is a genus of Neotropical silversides from the Lerma River basin in Mexico, including lakes Chapal and Pátzcuaro. Fish in the genus collectively go by the common name charal/charales in their native range (a name also used for the related Poblana). They are heavily fished, but several of the species have become threatened due to habitat loss (pollution, water extraction and drought), introduced species and overfishing. Three species are considered extinct: C. bartoni (disappeared 2006), C. charari (1957) and C. compressum (1900). Four others have not been recorded recently and may also be extinct.
