I am assuming this is a misprint, but maybe this is a thing. I had never heard of yellow perch spawning at anytime other than just after early spring, usually just after ice out. Any thoughts? I do realize that they have a reputation of questionable claims, but maybe it's a thing.
This looks like the annual Zett's catalog which as text in it from 1966, I think.
I think it's a mistake that 's probably been there for a long, long time.
Excerpt from Robert Crais' "The Monkey's Raincoat:" "She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
In a laboratory setting or in an indoor aquaculture setting where you can manipulate water temp and photoperiod, you can get Walleye to spawn every month of the year. Not the same females and males though. My wag would be that each fish could only spawn once a year.
If you read the Zetts 'catalog' looking for technical information, you'll probably not be so happy, or at least be confused.
Their fish, however, are very good. I've bought fish there for years with no problems.

I believe this to be true of perch , walleye and sauger as they have to go through a thermal cycle for eggs to properly develop. The cold side is what matters most.
