Rainbow (Oncorhynchus mykiss)Identifying marks are black spots on a light body and a red stripe along the sides of the fish. "Brookie" (Salvelinus fontinalis): The pectoral, pelvic, and anal fins are often orange, edged with black and white. The body is dark with white and red spots inside blue circles. Lake trout (Salvelinus namaycush) This fish has a white, irregular spot pattern on a dark body and veriform markings over the back and head. Unlike other trout, they have a deeply indented tail fin.
