I'm curious, with all the interesting discussion about RES and RES hybrids on this forum, how did the Iowa DNR determine this is pure RES? Or do they do a visual on it?

My uncle caught what wouldve been the state record channel cat in a river not known to harbor blues. The state biologist couldnt tell due to damage to the anal fin so they had it DNA tested but filled out the paper as a channel cat. DNA came back a blue cat.
