Some years they spawn once or twice in spring. Some years they spawn on and off all summer. One year none of them spawned that we know of. I think that was the year 2002. My koi do not eat their fry and now that they're getting large they ignore most of the eggs as well.
When koi eggs are fertilized, they cling to pond plants for three to four days. Once they hatch, they sink to the bottom of the pond. These baby koi are called koi fry. Once released from their yolk sacks, the baby koi take cover in pond plants. Baby koi do not typically need to be fed in the first few days.
