Zero way to tell if its a smallie or a meanmouth without analyzing DNA. We have gone over this over and over and over......
Sadly, I came to the party late and didn't see any of those discussions.
Having moved from Tennessee only 2 years ago I have seen plenty of the mean mouth hybrids. One thing they "usually" had was the coloring of the smallmouth with the vertical bars, but also had a LATERAL LINE. Does that fish in the pic have a faint lateral line or is it a reflection?
Like everyone has said though ... nice fish either way.
