• Use fyke nets at upper end of Yampa Canyon to intercept and remove adult
channel catfish migrating downstream into Yampa Canyon to spawn. Use fyke
' nets (and possibly angling) at lower end of Yampa Canyon to intercept and
remove subadult channel catfish migrating upstream into Yampa Canyon to
' recruit into the adult spawning population.
• Identify the need for channel catfish control programs in the Duchesne, White,
and Colorado rivers, and develop control strategies using programs in the Yampa
' River and Desolation/Gray canyons as templates.
• Do not proceed with large-scale efforts to mechanically remove nonnative
cyprinids from backwaters and low-velocity habitats in the lower Green and
' Colorado rivers in Utah and in the Colorado River Colorado.
