Those are bitch ass perch. Worthless.
Fuck perch.
Perch are imvasive water rodents and live in warm cesspools. Whitefish are rugged, respectably large, and live in cold, swift mountain rivers, side by side and in harmony with those fish you named. The hate makes no sense.
Coho (silvers) are soft fighting, marginally decent eating, and have lockjaw 99% of the time. They're trash fish everywhere south of British Columbia in my book. I wish I never had to see one again. I'd rather go nymphing for whitefish than waste my time targeting them.
I think chuck's drunk or needs to catch more b-run coho on the peninsula. They aren't soft fighters - well, they can be, but that's not their reputation anywhere I've been. A fresh buck coho is an excellent eating fish, and coho are only lockjawed until the water cools and gets moving, then they destroy anything you put in front of them, with only occasional periods of lockjaw. I've eaten whitefish a number of times - it doesn't compare to saltwater-caught or late-season coho, IMO.
Rugged? You can find coho in every little trickle of a creek way the fuck out in the middle of the woods because they bust their asses up every creek and stream that will hold them.
I'm an oncorhynchus guy. What the hell is a prosopium? Fish with a stupid face?
Fly guys. They just talk crazy sometimes.
