Looking for pallid sturgeon

December 22, 2010 | 5:45 p.m. CST
Biological Technician Rebecca Welly from the U.S. Geological Survey holds the end of a pole that guides a receiver. Its submerged end is intended to locate tagged pallid sturgeon in the Missouri River. Welly is a part of a small team of scientists that frequently go out on the river to check on the reproductive condition of the pallid sturgeon to see, and in some cases ensure, successful reproduction. Whenever the team catches a pallid sturgeon that they have not caught before, they implant a tracking device that can be used to determine if the fish mated as well as the water depth and temperature.
