A system and method for controlling the flow of fish. The system includes a vessel containing water and having an exit aperture. The system also includes a sensor configured to sense a first fish moving through the exit aperture. In addition, the system includes a jet device in communication with the sensor. The jet device is positioned adjacent to the exit aperture and is configured to spray a jet to prevent a second fish from moving through the exit aperture. In one embodiment, the system also includes a gate positioned at the exit aperture, the gate being normally closed and configured to be pushed open by a fish moving through the exit aperture. The system may be employed for providing spacing between fish or may be employed to provide a single fish on demand. |
