A cross of the Hofer strain of disease-resistant rainbow that was found in Germany in 2002 is reproducing successfully in Colorado rivers. “For the first time since whirling disease decimated most naturally reproducing rainbow trout populations throughout Colorado more than a decade ago, new strains of rainbows have reproduced naturally in the Gunnison River and in ponds located along the Frying Pan River near Basalt.” In The Coloradoan.
