It's usually used for stream surveys. An electrical current temporarily stuns the fish (has something to do with the air bladder that keeps them upright while they swim, I think). The fish are measured and sometimes weighed and are released no worse for wear. There is a device that provides the current and someone hold rods in the water to deliver the current. It's sometimes called telephoning because they used to use old fashioned hand crank telephones to produce the electricity.

In most states it is illegal so check with your local DNR. As for how you need an antique "crank" telephone and two long 8 gauge wires. the wires attach to the crank inside the phone box, one hot side one ground and the other end goes into the water then you crank up the amps. Before you ask no a battery will not work.

it got its name from back in the day when people would take old telephones and crank them while in the water, stunning the fish and they would grab them when they floated to the top. now its called Electra shocking and stream biologist use the same general idea to collect data. after a little bit the fish are back to normal and swimming around like nothing has happened. but dont try this its illegal, big fines for it.
