Almost all fish will eat their own and other fishes offspring which is why
they have so many at a time to allow a small fraction to reach maturity.
You don't say what kind of fish they are? - you mentioned goldfish - do you
already have adult goldfish in the pond?
As long as there is somewhere for the young to hide (plants, netting etc)
the adults will spawn every year...remove the plants and they won't spawn.
There is always the possibility that they are not young goldfish at all,
many birds inadvertently carry fish eggs to other waters so they could be
almost anything!
