Yikes, I never knew they lived that long. I figured under ten years.

That's amazing!

It was caught near the Apostles, and they're old.

What amazes me is that that trout only grew by 8 inches in 36 years!

I wonder how much more body mass it put on?


I know even the BWCA because of limited fish diet lake trout can be 20 inches and maybe like 15 years old. I know age-growth studies done in Quetico a 9 year old measures 21.3 years old on average and a 16 year old fish averages 16 years old. A northern pike on the other hand is like 20 inches at age 3 quite often(depending on the water and if not limited by food supply).
What helps on the old age thing for lake trout is they live in cold water and thus much of the year their metabolism is slow.
