Fish processing device

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.
