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.
Male Koi will be ready to breed when they are 2 years old, but females should be 3 years old. It is possible though that younger Koi will breed but their offspring will be of poor quality. Eggs are spawn and sperm is milt. The female is capable of carrying around 100,000 eggs for every 1kg of body weight.
