HOW DOES IT WORK?

Fishing clean end easy

An electric field generated  between two electrodes inhibits the witting  motions of fishes (anaesthesia). For certain field values, it is even possible to stimulate a directional forced swimming (electrotaxis). Thanks to that, fishes are attracted to an electrode where they can be caught using a dip net. For an optimum value of the field, the fishes recover from anaesthesia without any after-effect as soon as they are taken away from the electric field.
