From the Knox News:
"No one had ever seen a smoky madtom - scientific name Noturus baileyi - until 1957, when biologists treated Abrams Creek in the Smokies with a commonly used poison called rotenone to reduce the rough fish population and improve trout fishing.
Among the scores of fish killed was a miniature catfish, complete with tiny whiskers. The scenario was classic good news-bad news: the good news being the discovery of a new species, the bad news being that it was already dead."
It wasn't already dead, actually...They had just killed it!
