Did you know that a lake trout's brain actually grows in the winter? That's right-when the water gets cold, these incredible fish devote more energy to their brains, enhancing their cognitive abilities for complex reasoning. This astonishing discovery challenges everything we thought we knew about fish behaviour!

In this mind-blowing episode of Doc Talks Fishing, we sit down with fisheries scientist, Evan Versteeg, who discovered that lake trout brains *literally grow larger* in cold water when these cunning predators sharpen their cognitive abilities to outsmart prey and survive in frigid conditions. But when summer rolls around, their brains shrink as energy shifts to other survival needs. It's a stunning adaptation that reveals just how dynamic these fish truly are.
