The biannual electroshocking fish survey conducted by fisheries officials from the Utah Division of Wildlife Resources (DWR) on the Green River below Flaming Gorge Dam allows biologists to determine the size and health of the trout population. This year, Brett Prettyman of The Salt Lake Tribune went along for the ride and provided some great video that shows how the survey process works, as well as how the electric current actually affects the swimming trout. The underwater footage is particularly cool.
