Lake Trout
Dark grey or blackish-green sides with white or yellow spots are the typical calling card of the Lake Trout. During spawning their coloration changes to orange sides and fins, which may serve to attract mates. They are dwellers of the deep, living in some of the deepest lakes on earth. Although very large Lake Trout have been caught, they average 5 to 12 pounds and 12 to 18 inches.
