How to identify a Rainbow Trout
The rainbow trout coloration varies greatly with size, habitat and spawning periods. For example, stream dwellers and spawners usually show the darkest and most vivid colors and markings, while the steelhead is silvery when it returns from the sea. Though noted for the broad red or pink stripe along the middle of its sides, this stripe may not be present on all forms, particularly the sea-run steelhead and immature specimens in clear lakes.
The spots characteristically extend onto the dorsal fin, the adipose fin, and the tail. Those on the tail radiate outward in an even, orderly pattern. Spots may or may not be present on any of the lower fins and there are never any red spots such as occur on freshwater and spawning specimens of brown trout and Atlantic salmon.
