I've seen that same thing happen in Lake Apopka near my home town. Lake Apopka is a very polluted, over enriched lake and the fish populations are way out of balance. The "junk" species of gizzard shad are way out of control. They are in huge schools and will fly out of the water just like in the video. I've been hit in the head with a shad and I can tell you it is no fun.
Speaking of no fun, there are annual reports of fish jumping in the Suwanee River and rivers in North Florida. Unfortunately for the boaters they are alligator gar and sturgeon that can reach upwards of 100 pound. A man was killed a year or two back when a sturgeon leapt out of the water and struck the man unconscious. His boat ran into the bank at speed and he was killed. Not a way to go IMO.
