You can easily identify an American Shad because is a silvery fish with a single dorsal fin in the middle of the back. There is a large black spot directly behind the top of the gill cover, followed by 4-27 spots, which are generally smaller than the first. Sometimes there may be a second row of spots below the first, and more rarely, a third row below the second. They closely resemble the hickory shad.
