#49 || Dr. Chris Therrien: Three Mind-Blowing Fish Facts You Absolutely Don't Know

We welcome back Dr. Chris Therrien for a jaw-dropping conversation that will change how you look at fish. Did you know that male bluegills will disguise themselves as females to sneak past aggressive males and steal fertilizations? Or that most —maybe even all— of the world record Arctic char caught in the legendary Tree River are likely Dolly Varden trout? Using cutting-edge genetic analysis, traditional ecological knowledge and meticulous field research, scientists have rewritten what we thought we knew about these iconic fish.

But perhaps the most astonishing discovery is Mary Catherine— a tiny 4.6-pound, 25-inch lake trout from Lake Superior that's 62 years old. Yes, a fish old enough to have watched the Leafs' win their last Stanley Cup in 1967. Chris explains the fascinating science behind extreme longevity and why that "small" fish you just caught might actually be the oldest fish in the lake. Whether you're an angler, nature enthusiast or simply someone who loves learning mind-bending fish facts this episode's for you.
