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 female should be isolated in a pond by herself, with other females, or with young koi for at least 24 hours, so she can recuperate. She will lose the spawning odor and have a chance to rest in this length of time. Otherwise, she may be subject to further harassment by males not previously involved.
