I fish in Colorado more often now, then when I lived there. The past three years I have spent at least some of my time fishing or looking for places to fish. I have caught stocked fish, wild fish, and native fish. We have determined that replacing natives with exotics is morally and biologically equivalent. While one can plead naivete in many of the original decisions, we continue to make the same mistakes over and over again.
Ignorance is no longer an excuse.
The Yellowfin is apparently now extinct. Exotic cutthroats have been stocked in some watersheds, and active projects toward native restoration are going on in several locations. In all honesty, though, I have to acknowlege that where there are wild populations of Browns, Brookies, and Rainbows in Colorado, that their wildness requires a certain amount of respect. At the very least, let's not lose any more native trout, and let's try to restore them as much as possible. I think this can be done without laying waste to existing populations of exotics, although where cutthroat are being restored, any brook trout will have to be removed, since they tend to displace the native trout.
