Abstract: An electrically insulated water containable member has a first electrode and a pair of second electrodes bracketing the first electrode. A source of electric power is connected across the first electrode and each electrode of the pair of second electrodes to develop an electric field within the member between the first electrode and each electrode of the pair of second electrodes, which electric field causes narcosis or tetany in any fish present in water within the member and between the pair of second electrodes.
Abstract: To minimize injury during electrofishing while inducing a high degree of electrotaxis, a packet of DC pulses having sharp leading edges and preferably an exponential or square decay are transmitted under water between an anode electrode and a cathode electrode several times each second to stimulate contraction of the red muscle tissues and bring about electrotaxis without inducing epileptic seizure of the white muscle tissues of fish and thereby avoiding injury to the fish. The power level of transmission is reduced between the packets.
