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 have heard of koi spawnign in the Fall, but I suspect those females didn't spawn the previous spring. also not every female will spawn every spring. This last spring I only had one of my females develop eggs.....the rest.......nutin honey.
