Sep 04, 2019· Additionally, because the electrical flow is all in one direction, Galvanotaxis is achieved with this waveform. When used appropriately, PDC provides tremendous benefits while simultaneously reducing the downsides associated with other waveforms. For these reasons, PDC is the most frequently used waveform when electrofishing.

Finally, if your electric field pattern has been mapped, you can determine the size of the electric field generated by the threshold setting that lead to "successful" electrofishing or acceptable capture efficiency. This electric field size would be the size required for successful electrofishing.
