I've been watching that shad cam for many years when the shad are running. Late night seems to be the best time. Some very interesting fish moving thru there then! When I was tying flies commercially, which I gave up about 10 years ago, I often sat & tied late at night, so would watch the cam as I tied.
As near as I can recall, I've seen both American & Hickory shad, gizzard shad, bullhead catfish, channel cats, lampreys & American eels, White & Yellow perch, Crappies, some small LM bass, Striped Bass, and a few other catfish that I'm not positive about the exact species.
Very cool to watch!
