pond fish breeding

[tracey061196]

I have a large garden pond (approx 30ft x 25ft, and 4ft deep) in the pond i have 15 Goldfish, 20 Koi Carp, 2 common carp, 2 grass carp, 2 tench, 2 rudd, 2 roach, 1 ghost carp, 1 mirror carp, the largest being about 7inches long, the rest about 3-4 inch. My goldfish have been spawning and i could see many eggs around the side of the pond, i have noticed that there are not as many eggs as last week, Would the other fish eat them? if so what would be the best way to keep them.
