Featured Species: Chihuahua Catfish (Ictalurus sp. Chihuahua Catfish)

by Dr. Dean Hendrickson (Curator of Ichthyology)


The very rare and still scientifically undescribed Chihuahua Catfish, "Ictalurus sp." is known only from streams of the Río Grande basin. It looks superficially a lot like the common Channel Catfish (Ictalurus punctatus), and hybridizes with that species. Non-hybrids, however, are identified by a shorter head, more rounded tail fin, fin ray counts and other details, not to mention DNA. It has not been collected in Texas for a couple of decades, but persists in New Mexico and probably still Chihuahua, Mexico.
