I honestly don't know if the Canadian Geese will eat fish or not. I do well remember that as a youngster we had a farm pond in the pasture that was loaded with stunted bluegill. We also had a couple of the big white domestic geese, and those suckers would walk right up next to you and wait for you to catch a fish. In those days, runt bluegill found their way up on the bank, not back into the pond. They would fight to see which one would devour the fish first! That's the basis for my fear of geese, although you may very well be right about the canadians.
