This document provides guidance for making electrode measurements on various gear types, using an external power source and an internal power source.
The external power source approach (Battery Method) is presented first with two parts. The first part covers resistance measurements for a 2-boom boat with the hull as the cathode. The second part addresses resistance measurements for electrofishing units with one anode and one cathode. This second part refers to measurements on backpack shockers, single-boom boat shockers, single-anode tow barges).
The internal power source approach (Power-on Method) is then presented.
