Do you know how many sub-species of cutthroat trout there are? How about: How old is the species? Why are there so many sub-species of cutthroat? This episode Dr. Pat Trotter joins me, the world’s preeminent expert on cutthroat trout. Pat has written two books on cutthroat, authored book chapters and numerous scientific publications. He is also a long-time angler and has spent a large part of his life roaming Western watersheds to better understand cutthroat trout.

Tune in to hear about how Pat became interested in science, why he loves cutthroat so much, how their evolutionary legacy has been shaped by geology and hydrology, and which sub-species are most at-risk. Even if you thought you knew cutthroat, this episode will teach you at least one or two new facts.
