The only way to get rid of hawks is to remove their food supply from the territory in question. Scaring them off doesn't work, as they're quite intelligent, and and learn the methods of repelling them very quickly.
you can hang CD's from strings high up. The wind will spin them causing flickering lights this can distract hawks or scare them away entirely. You can also get a fake hawk this will work because hawks are very territorial. Unfortunately this won't work forever because they will get used to the hawk and figure out its a fake.
Make the pond deeper so that the fish can dive down deeper to escape the hawks.
Bear call!
its unlikely you can stop a fish from eating another fish without taking that fish that's being eaten out of the fish tank.
The fish maybe have a pregnant.
Most hawks don't eat fish. Most hawks eat mice, voles and birds, not fish.
