Chinook Salmon

Lake Michigan Sunset  Taken By:Jerek Obry

How do I know it is a Chinook?


Appearance: The body of the Chinook, like the rest of the Chordates, is bilaterally symmetrical and highly cephalized(shows a distinct head region). The Chinook salmon exhibits a black dorsal (top) region, silver sides, and a white ventral (bottom) region.  Black spots are scattered along the entire upper portions of the fish like freckles.  The head is generally darker in shade with a white lower jaw.  The mouth of the fish is relatively large for engulfing larger prey (see Nutrition).
        The Chinook salmon displays two dorsal fins.  The anterior (closest to the head) dorsal fin is much larger and matches the colors of the dorsal surface while also displaying black spots.  The posterior dorsal fin is much smaller and dark in color, similar to the dorsal surface of the fish.
            Five ventral fins can be noted on the ventral portion of the fish.  These, unlike the dorsal fins, tend to be lighter in color with relatively dark tips.
            Finally the fish flaunts a large symmetrical tail fin.  The fin is darker in color and carries the same spots as seen on the dorsal portion of the rest of the body.
