Young Dean, ready to go fishing with dad...

It got me reflecting on what a big role that group of fishes has always played in my life. From diapers through late teens, I spent all of most every summer at that family cabin on an Arizona mountain stream stocked with non-native Rainbow, Brown and Brook Trout. I was pretty good at fishing, and quickly addicted. Anyone under 14 fished free, but could take only a half limit. Since I could almost always catch more than 5 a day, starting about age 9 I invested annually in a license (I think Mom may have picked up the bill to start - she loved pan-fried trout for breakfast!). By my early teens, deeply into fly fishing, which provided great insights into aquatic biodiversity and ecology, my career plan focused. Then my first real job, as an undergraduate, sent me deep into New Mexico's Gila Wilderness for a delightful summer with my supervisor, a couple of mules, and a backpack fish shocker, to sample the endangered Gila trout for genetic research. I was in heaven and never looked back. Another degree and a couple jobs later, while sampling fishes in the remote mountains of Chihuahua, Mexico, my shocker turned a trout that looked like a rainbow, but differed in many ways. The scientific literature then documented only one native Mexican species (not the one I'd caught) and most experts believed other records of trout in that country represented introduced rainbows imported from California. That conclusion was anything but solid, and it was clear that huge areas had yet to be sampled.
