The only time I've seen FA or fungus grow on yellow perch eggs is if they are not fertilized or they are dead for some reason such as laying on the bottom or getting smothered with silt. Did you get a heavy rain event that covered them with silt and subsequently with FA? Also keep in mind that just before eggs hatch they look pretty ragged and the left over byproducts could accumulate fungus or algae.

As prolific as yellow perch are I find it hard to believe you would have trouble getting them going in a pond via natural reproduction. Only other thing I can think of is intense predation by carnivorous insects or other fish but even then there should be sufficient survivors. Each perch can produce a few hundred thousand eggs.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
