sometimes surrounded by bluish halos on their sides. The lower fins have a white front edge with black and the remainder being reddish
orange. The tail fin is square or rarely slightly forked. During breeding time in the fall male brook trout can become very bright orange-red
along the sides.

have a distinct, irregular brownish mottling over a light background. The belly is creamy white. They have square tails and 20 to 24 anal ray
fins.

distinct dark, vertical bar below the eye. The cheek and gill covers are completely covered by scales. The underside of the lower jaw has 14-
17 branchiostegal rays.
