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.
Koi offspring will usually hatch after 3 to 7 days, depending on the water temperature. If the water temperature is around 20 degrees C/ 68 degrees F, the eggs will hatch after 3-4 days. You know that the hatching will take place within a day when the eggs develop a special shiny look.hen the female deposit her eggs at the spawning mop, the males will immediately fertilize them. The spawning mops can then be removed and placed in the fry raising pond. During Koi breeding, it can be a good idea to add 0.2 mg of malachite green for each liter of water in the fry raising pond to prevent fungus attacks.
