Lake in the Wind Rivers (IMAGE)
Caption
University of Wyoming researchers ply the waters of an alpine lake in the Stough Basin of Wyoming’s Wind River Mountains as part of their research into the impacts of trout stocking in the once-fishless lakes. Among their findings is that trout from lakes stocked decades ago in the Wind Rivers have evolved to develop more gill rakers, which are bony or cartilage structures in the gullets of fish that act as sieves to retain zooplankton and nourish the trout.
