The cover photograph was taken on the Colorado River a few miles below Potash, Utah, on June 9, 2003; it was
provided by, and is used with permission of, Doug Osmundson, U.S. Fish and Wildlife Service, Colorado River Fishery
Project, Grand Junction, Colorado. Agencies electrofishing in the Colorado River Basin have instituted measures to
minimize harmful effects on fish, including injuries such as the extreme example illustrated in the inset X-ray. That
dorsal-view X-ray of spinal misalignment and fractured vertebrae in an electrofished rainbow trout (Oncorhynchus
mykiss) was provided in 1991 by, and is used with permission of, Norman G. Sharber, Flagstaff, Arizona.
