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.
I only get one spawn per female per season. I think the shorter summer and cooler weather in the PNW compared to, say, Florida, may effect how many times they spawn. My Koi started spawining last month. I usually dont see babies grow up because my fish eat them.
