Let’s just add musky on top of that…
I agree with your point Glenn as I grew up there and have never been a fan of the DNR experiments.
While I am unsure if the addition of catfish to this ecosystem has played a significant role in reducing the average size of panfish, I can assure you that muskies have not. Muskies do not seek out and target sunfish. They’re preferred prey are soft rayed fish such as suckers and ciscoes. Secondarily they may target perch. Would they take a large sunfish or crappie if given the chance? Perhaps. But stomach content studies have shown they do not have a measurable impact on bluegill populations.
The likely cuplrit is over harvest by anglers.
