Dave Philipp made the case for two separate species in 200, but I don't believe that it has been formally accepted yet. The book "Common and Scientific Names of Fishes from the United States, Canada, and Mexico" published in 2004 does not distiguish the two as separate species. That book is generally considered the authority by most scientists. For all intents and purposes, a sub-species and strain are the same thing.
