Fish processing device
View Patent ↗A fish processing device and method of use, the device including: a channel; a sensor located within or adjacent to the channel; a barrier, the barrier to assist in preventing a fish passing through the channel; and a control system, wherein the control system controls the barrier in response to an output of the sensor. The method including the steps of: detecting that a fish is incorrectly orientated in a channel; and controlling a barrier to assist in preventing the fish from passing through the channel.
1. A fish processing device, the device including:
a channel adapted to allow a fish to move through the channel, wherein the channel is adapted to allow a water current to pass through the channel thereby encouraging the fish to move through the channel;
a barrier located in the channel, wherein the barrier has an open position and a closed position;
a sensor associated with the channel; and
a control system in communication with the sensor and the barrier, wherein the control system and the sensor are designed to detect a first or second orientation of the fish, wherein the fish is in the first orientation when a dorsal surface of the fish faces upward and wherein the fish is in the second orientation when the dorsal surface of the fish faces downward;
wherein when the fish is in the first orientation the barrier is adapted to allow the fish to pass through the channel, and wherein when the fish is in the second orientation the barrier is adapted to assist in deterring the fish from passing through the channel by engaging the fish, and
wherein the control system is adapted to control the barrier in response to an output of the sensor, wherein the control system moves the barrier toward the open position when an output of the sensor senses that the fish is in the first orientation in the channel.
2. The fish processing device according to claim 1 , wherein the channel is designed in that the fish are enticed to swim through the channel by a water current.
3. The fish processing device according to claim 1 , wherein the channel is enclosed forming an internal passage.
4. The fish processing device according to claim 1 , wherein the sensor is a visual sensor.
5. The fish processing device according to claim 4 , wherein the visual sensor is adapted to detect the different colors between the dorsal surface and a ventral surface of the fish.
6. The fish processing device according to claim 4 , wherein the visual sensor is adapted to detect the different shape between the dorsal surface and a ventral surface of the fish.
7. The fish processing device according to claim 1 , wherein the barrier includes a gate having a panel and an actuator.
8. The fish processing device according to claim 7 , wherein the panel is moveable from an open position to a closed position by the actuator, wherein the open and closed positions of the panel correspond with the open and closed positions of the barrier, respectively.
9. The fish processing device according to claim 8 , wherein the panel is pivotable about a point for moving the panel from the open position to the closed position, wherein when the panel is in the closed position the fish is prevented from passing through the channel thus deterring the fish.
10. The fish processing device according to claim 1 , wherein the barrier includes a jet of air to deter the fish.
11. The fish processing device according to claim 1 , wherein the barrier includes a light source to deter the fish.
12. The fish processing device according to claim 1 , wherein the control system further includes an alarm to alert an operator if the fish is in the second orientation in the channel.
