Settings Calculator

Getting your settings right is the difference between a clean, safe survey and stressed or injured fish. This tool gives you a starting point for your e-Fish 500 before you step into the water.

Enter the water conductivity and temperature from your meter, choose the fish you are targeting, and the calculator will recommend a voltage, pulse frequency and duty cycle — then show you the resulting waveform, an estimate of the effective field around the anode, and how hard the unit will be working.

Figures are indicative starting points only, based on general electrofishing guidance. Always begin at the lowest effective setting, observe fish response and adjust. Operators must be trained and follow their organisation's risk assessment and Environment Agency guidance.
