I know what you are saying and I agree....keystone predators have the most contaminants because they eat the fish that eat the fish that eat the fish that eat the fish that have contaminants and it builds up.Dude, it's much safe to eating a 22" pike than a 55" muskellunge. I got super ill from eating a 45" northern pike two years ago. Massive stomach aches and pass out randomly at different times. Mercury levels in small fish isn't same levels in larger fishes. That's why it's recommend to eat a larger fish (minus trout and salmon) over 28" per one month. I knew few people get sick from eating 30" walleyes and larger pikes they caught. It doesn't matter if you cutting up the larger fillets in small ones, it's too much mercury in the fillets.
What I am saying is contaminants can be found in any fish, not just the big ones.
Now catching a 50" trophy Musky and killing it only to NOT go get it mounted (or eat it ). Simply idiotic. Thinking I would expect from single-celled organisms, not humans or anything that requires food to live.
