The center picture is also a Brown, it lacks the vermiculations on the back that Brookie's have.
Juvenile Brown's often have a white edged anal fin, it generally disappears as the fish matures.
Trout - dark spots on a light body - pure white mouths
Char - (Brookie's) light spots on a dark body - black gums
This is a cut paste general descriptor.......
"The first thing you should look at is their spots. Are they lighter than the rest of their body, or darker? If their spots are lighter, it’s probably a Brook Trout. If not, chances are it’s a Brown Trout. While you’re looking, check out the halos around the spots. These will have a bluish tint on Brookies, but will be plain whitish on Browns.
Another clear sign of which fish you’ve caught is its markings. Brook Trout have a distinctive wormlike pattern on their backs. They also have white edging along their lower fins, as well as the bottom of their tail. Brown Trout don’t have any of these things. (Note*--- that is somewhat inaccurate as I noted above)
Still can’t tell what you’re holding? Take a look at the tail. Brook Trout have splotches and spots all over their tails. Brown Trout tails are usually plain, with a few spots on the top half at most."
