Electrofishing: simplified explanation of voltage, current, power…

A moderate water conductivity is most efficient for electrofishing (see graph above) because it uses a moderate amount of current and voltage to successfully catch fish. Further, the conductivity of a fish is in this moderate part of the range, and therefore, electrical current flows through the water and fish very efficiently at these conditions.

Electrofishing: What is it and how does it work?

Electrofishing involves generating a field of electricity in the water which temporarily stuns fish in the close proximity (~5m) so that they can be scooped up with a dip net. ... (1000 volts), lifejackets and rubber soled …

New Perspectives in Electrofishing

The basic concept for circuit layout of an electrofishing system is straightforward. It involves both parallel and series circuits. ... If the voltage is set at a higher level than the generator can supply, the circuits compensate by automatically decreasing the pulse width to maintain output voltage. Peak voltage is the most important parameter.

Things to consider when electrofishing

There are some low conductivity situations where electrofishing is going to be incredibly inefficient and frustrating. Distilled water has a conductivity range of 0.5 to 5.0 µS/cm. If typical electrofishing voltages (100 to 1,200V) are applied to water of this low of conductivity, very little current will flow.
