• 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,

cyprinids from backwaters and low-velocity habitats in the lower Green and
Colorado rivers in Utah and in the Colorado River Colorado:
