Electrofishing Services

We routinely carry out electrofishing surveys for clients, either with our boat electrofisher or our backpack electrofishing equipment. Boat electrofishing is suitable for larger streams, rivers and lakes and we are set up to conduct boat electrofishing surveys from both our jon boat and our smaller inflatable zodiac. Backpack electrofishing is suitable for smaller systems and other waterbodies that are not accessible by boat.

What is Electrofishing?

Electrofishing relies on two electrodes which deliver a current at a set voltage from an anode to a cathode through the water. This current creates an electric field which attract fish towards the unit being powered. The attracted fish become stunned for a limited amount of time, often turning onto their back, giving the surveyor enough time to capture them. Electrofishing is a non-lethal survey method, affecting fish for a few seconds or minutes, depending on the size and the type of fish species.

Electrofishing is used as a scientific survey method to sample fish populations and determine a variety of factors including species presence/absence, species abundance and species health. We routinely use electrofishing in Environmental Effects Monitoring to capture sentinel fish species.

A list of safety procedures and practices must be followed when using either type of electrofishing. The Kilgour team is certified in the use of backpack electrofishing equipment (Class 2 Electrofishing) and certified to drive boat electrofishers (Class 1 Electrofishing). We can also provide training in the use of electrofishing equipment.

Electrofishing Services in The Ottawa and Surrounding Areas

We routinely provide electrofishing services for our land development clients to assist with various types on in-water works, including stormwater management pond expansions, culvert replacements, channel realignments, and works related to canal wall and lock replacement or repair. Electrofishing can be an effective means of conducting fish removal and relocation programs for construction projects.
