I thought the bigger fish were eating all the eggs until last year
when I captured a mat of eggs and put them in a separate pond. I now
think there wasn't enough food for the eggs when they hatched. I ran
across a post from Brett (a trusted name) some time back and found
this one first today so I quit looking, but they have about the same
ideas. Perhaps Reel has a better experience and ideas too.
I cut this from a post on Koiphen's:

3 days is about the right time for the "dwindles" to hit a tank of
fry.
Although it is certainly possible to rear fry totally in captivity,
they require some living food early in their life to set their guts to
working right. By three days they are very much in need of nutrition.
Artificial diets might keep them alive for that long, but that is also
when we at the hatchery remove the fry from the hatchery to plankton
ponds.
Next time you get a hatch, set up a second tank to raise them some
food. Aquarium people call it "infusoria" and they will have many
recipes for brewing it.
One recipe I know of that works pretty good.....
In a 100 gallon container that has some aeration and dechlorinated
water add the following...
One quart of hard boiled iceberg lettuce and the "juice" it was boiled
in.
One good armful of fresh hay or a gallon or so of dried grass
clippings.
One quart of "live" water from a watergarden pool, standing water in a
ditch, or if nothing else, water from the fish pond.
What you're shooting for here is rotifers, glass worms, and other very
small plankters that are not easily seen with the naked eye. If you
see stuff easily that is swimming around like little "bugs" you either
got Daphne or Cyclops, both too big for the fry to eat, and big enough
to eat the fry. These are good foods for two week old fry.
