Native Fish of the Rio Grande
Only about one-third of the native fish species known or likely to have occurred historically in the Rio Grande of southern New Mexico and west Texas can still be found there. The others have disappeared, the victims of dams, channelization, disruption of natural flow patterns, droughts, and habitat loss.
The missing include shovelnose sturgeon and American eels, both commercially valuable species in other parts of the U.S. See the complete list below.
There is hope that these natives can one day be returned, if their habitat can be restored and flow needs met. Only one species has gone extinct--the phantom shiner. The others can still be found elsewhere.
The Southwest Environmental Center is working to restore as many native fish as possible to the Rio Grande through advocacy and on-the-ground habitat projects like the La Mancha Wetland. We also recently released a report detailing a novel way to restore habitat in the Rio Grande for native fish (see attached PDF).
