High Conductivity Water. Ocean water conductivities are generally between 30,000 and 50,000 µS/cm. Whereas when electrofishing, high water conductivity is anything over 2,000 µS/cm. In high water conductivity conditions, most current will flow through the water in a small electric field and the fish will hardly be affected.

Electrofishing, Theory. When undertaking electrofishing activities your ultimate goal is to generate an electric field in the water that will attract and temporarily immobilise the fish within it, but with minimum distress and no long-term harm to them. To achieve this you will need control the properties of the electric-field by choosing ...

An electrofishing unit puts out an electric field into the water so that fish in close proximity (2-4 feet) can be "stunned". Typically, when a fish encounters the electrical field their muscles contract, drawing the fish towards the electricity, which allows the biologist to net and place the fish in a bucket of fresh water.

Electrofishing is a widely used and highly effective method of sampling freshwater fishes. However, power limitations currently restrict electrofishing to waterways with ambient electrical conductivities up to 5,000 μS/cm. At these higher conductivities, the electrofishing devices currently available are limited in providing the peak power ...
