The University of California, Davis has recently discovered that the McCloud River Redband Trout, also known as O. mykiss calisulat, is a distinct subspecies of rainbow trout. This marks the first time a new subspecies of Pacific trout has been identified since 2008, and is the most recently identified subspecies of rainbow trout, with a gap of over a century since the discovery of the previous one.
 

Fish biologists have long suspected that the McCloud River Redband Trout was a distinct subspecies, but it was not until the use of more advanced genetics techniques, including genome-wide DNA sequencing, that the UC Davis-led team was able to confirm this suspicion and solve the puzzle, as stated in a corresponding study published in the journal Zootaxa.
