I doubt that the fish would survive the possible journey and then the drop to the water.
Perhaps, but how long can a small fish survive out of the water? One minute? I think that is possible. . . . .
How far can a bird fly in a minute? . . . . Surviving a drop to the water?
My kingfishers sit on branches that are 6 to 10 feet off the water all the time. That's nothing for a fish to fall. Heck, it wasn't that long ago someone posted an old advertisement of stocking remote lakes by dropping fish from planes.
