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.
The day before the Koi hatches the eyes in the egg will have a shine to them. Soon afterwards, the young Koi will begin to wriggle then, gradually, over the next few hours, it will break out of its 'shell'. It will take three to four days for the Koi eggs to develop and the fry to hatch at temperatures of 68 -7l.Koi fry can develop at temperatures as low as 63, in which case their incubation will take five or six days, or as high as 77, which will decrease their hatching time.mmature Koi may also eat the eggs, so if you want to rear them, you should separate the spawning Koi from others in the pond. Incubating Koi Eggs The incubator should have a reasonable capacity. A water storage tank about 100 gallons is ideal, and should be made of non-toxic materials.
