This study aimed to describe the influence of different electrofishing engine configurations on electric field dispersion in water. Several experiments with original results are included. The aims were to (i) assess the equivalent electrode resistances and the output voltage at the anode, (ii) assess the influence of electrode misuse on the dispersal of the electric field in water, (iii) assess the influence of the duty cycle and the frequency on the radius of attraction around the anode, and (iv) set the voltage and the duty cycle based on information from models for backpack and bankside electrofishing engines. A synthesis of equivalent electrode resistances from different studies was created. Using an oxidised anode induced a decrease in the radius of attraction. Frequency had no influence on the radius of attraction, in contrast to the duty cycle. Models including the voltage and the duty cycle were created to enable the configuration of electrofishing engines.
