A net is placed at the upper and lower ends of a 100 meter long stream section to survey. Rocks secure the bottom to prevent fish escape.

An electrofishing team consists of a least four people. The shocker controls the current which temporarily disables the fish. The shocker "sweeps" the fish into the nets, and they are transferred to a bucket of water. Three passes are made, less fish should be caught in progressive passes.
