In-Water Electrical Measurements for Evaluating Electrofishing Systems.
Abstract
The design of electrodes for electrofishing equipment is developed using in-water electrical measurements that apply to any electrode configuration, and the measurement techniques require only common, inexpensive electrical meters that are readily available to field biologists. Circuit analysis techniques are described for determining the voltage, current, and power requirements for an electrofishing system, and the relation between water conductivity and electrode resistance is demonstrated. Electrode resistance values, voltage profiles, voltage gradient profiles, and comparative indices are presented for 18 common electrodes. The fallacy of monitoring voltage, current, or power as a standardization procedure for electrofishing equipment is discussed in detail.
