I found some more information for those that think you need too harvest the big perch too reduce amount of eggs/baby perch... The info down below is on walleye but since perch and walleye are related that this may pertain too the bigger older perch as well.

This is copy and pasted from a thread I was reading...
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.
