ABSTRACT:
Low level electric fields are employed to direct fish movements without stunning or injuring the fish. The fields are generated by applying an electrical potential of no more than 25 volts to a wire submerged in a body of water containing the fish to be directed. In a first embodiment, the wire is disposed along the spillway of a dam, and directs fish, such as eels, away from the spillway, and toward an area of desired egress. A second embodiment is employed to contain fish or eels within a protective body of water, such as an open containment vessel, and utilizes a field generating wire positioned along the upper inner wall of the vessel.
