walleyes and egg production

[warmer]

Does a female walleye ever get so old that her eggs are not fertile? If so what age/weight does this happen?

I thought this was going to be a post of what was for breakfast. The title got me a little hungry.

Typically as a fish ages and gets larger they produce more eggs but the fertility of those eggs goes down. I was having trouble finding a specific journal article on walleye though. But here's two you can skim over.

I only read the abstract of the second article so not sure what age classes they looked at but it states the embryonic survival was better in older fish.
