ABSTRACT:
Anode and cathode electrodes are placed at the upstream downstream ends of an elongated tank containing fish to be electroanesthetized by applying an electric signal to the electrodes to create an electric field within the tank sufficient to induce petit mal in the fish. By maintaining a flow of water in the tank from the end containing the anode electrode to this end containing the cathode electrode, the fish will tend to head toward the anode electrode and be subject to the largest voltage gradient induced by the electric field. A barrier at each of the anode and cathode electrodes prevents contact by the fish to protect the fish against injurious electrical shock.
