I guess those fish are evening the odds from all those hawks swooping down and grabbing fish from the water. BTW, I actually saw that scene for real a few years ago. Out of the corner of my eye I saw a big splash in the lake out in back of our home. When I turned my head I saw that it was a hawk and at that moment it exited the water with a big fish in its claws.
Yes, I've seen that scene before on nature shows but to see it in real life was quite thrilling.
