Looking at the photos, I think we have some experts on the forum that could correctly identify them by visual inspection alone. However, I would have very low confidence that I personally could correctly differentiate the fish. (I have caught too many LMB on the same day that had broad color differences.)
FishinRod you are not alone! I have never met or heard of an expert or otherwise Fisheries Scientist who thought they could id a Fla or Northern or F-1 by visual inspection alone. Most will tell you that the only sure way is through DNA testing. I have seen info about counting lateral line scales and such but have no faith that it will give an accurate result.
