What is a pregnant koi called?

The question on "what’s a pregnant goldfish called" has been rather popular on my blog.

How about koi? The answer is the same. There’s no term for a pregnant koi since they can’t become pregnant. Their eggs are fertilised externally.

Next Wednesday, one of my students will be delivering a lecture about very fat, gravid koi that won’t spawn. What are the dangers of egg retention? What are other things that might present in this way… and how to fix it?

For more information, visit – A presentation about egg-binding (egg-retention) in koi fish.
