Abstract
A method of exterminating crustaceans in particular invasive crayfish species, in a freshwater watercourse, such as a shallow stream, said method comprising placing electrodes into said watercourse and applying a plurality of short pulses of high energy electricity to said electrodes. Said pulses may have a duration of around 5ms. In a preferred embodiment said plurality of pulses are applied to said electrodes over periods of time separated by dormant periods whereby crustaceans that may be in burrows or otherwise out of the water during a first period of pulses are exterminated during a subsequent period of pulses when they have re-entered the water, typically to feed on crustaceans killed during a preceding period of pulses. Also disclosed is apparatus for use in the afore described method.
