Not Too Shocking: Your Electrofishing Questions Answered
Electrofishing is a technique used in fisheries science to sample fish populations. Sampling is when biologists study a number of fish from a certain area, measuring and examining them and recording the statistics. When biologists electrofish, a generator or battery gives off an electrical current that runs through the water.

Electrofishing
Trawls, dredges, and encircling nets are used to capture fish in deep water (e.g., trawls, dredges, or purse seines) or to coral fish within an encircling net (e.g., round haul seine) or against the shore (e.g., beach seine). Electrofishing uses electricity to stun fish that are then collected using dip nets or seines (Reynolds, 1996 ).

The range of the power and the voltage provided by the electrofishing gear also limit the distance of the voltage gradient in water. If the power generator is limited, especially with high conductivity, the output voltage is low. In some cases, the transformer of the electrofishing gear also limits the output voltage.

Electrofishing 101: Understanding Pulse Type, Waveform, and …
Pulsed Direct Current (PDC) is sometimes referred to as Standard Pulse. It is the most frequently used waveform when electrofishing. PDC is seen as the balance between Alternating Current and Direct Current. With this waveform, capture rates are higher than those in DC and injury rates are lower, when used appropriately, than AC.

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.
