Electrofishing, Backpack Procedure


The diagram below shows the typical procedure used for surveying a section of river when working upstream with an electrofishing backpack (although this is not always necessary, and downstream fishing has been shown to also be effective).


  • The operator should walk in a zig-zag pattern across the water-course sweeping the anode in front of them across their path. Optionally the operator may choose to also use a catch net to capture and transfer to the fish holding bucket.
  • A team member should accompany the operator with a catch net and fish holding bucket.
  • Where possible, you should fish in a discontinuous manner, briefly switching off the anode at intervals (whilst keeping it in the water) such that fish are not driven ahead of the fishing team.
  • For survey work, it may be desirable to erect an upstream stop net to further fish entering the survey zone.

Please note that the E-Fish backpack is only suitable for wading fishing operations and should not be used from a boat or in combination with other electrofishing systems.

In addition to the general points discussed in the "Safety Considerations" page...


  • Do not allow unprotected parts of the body to come into contact with the water.
  • Only the backpack and anode operator should remove debris from the electrodes (anode ring and cathode tail), when they are sure the system is de-energised (and the Stop button is locked in).
  • Stop fishing if people or animals come within 5 metres of the electrodes
  • Do not allow the anode ring to leave the water.
  • Do not leave any live equipment unattended.
  • Do not simultaneously use more than one set of electrofishing equipment.
  • Never restrict access to the Stop button on the backpack.
