Norwegian Stingray with optical delousing system

2017-0421 Stingray delousing laserStingray software system is the only of its kind and a pioneer in robotisation and automatisasion of lice removal in the aquaculture industry.

By using stereo camera vision, advanced software and targeted laser, lice removal is fully automated around the clock, seven days a week throughout the year, without any handling of the fish. The stereo camera and proprietary software detects lice as the salmon swims in the pen. A guided laser pulse of up to 150 milliseconds “pulses” directly at each individual louse. The louse is hit with a fatal result, and coagulates within milliseconds. Due to the mirror-like skin of the fish, the salmon itself is not harmed. The skin reflects the light, while the louse absorbs it. Laser treatment is therefore a very gentle lice treatment for the fish.

Why Optical Delousing?

Optical salmon delousing allows the fish to swim undisturbed in its natural habitat while being deloused. This means:

  • no handling
  • no starvation before delousing
  • no crowding
  • no chemicals
  • no damage to fish or environment
  • no fish death

The fish farmer avoids demanding and inexpedient operations, saves labour costs and manual operations, and gets fewer lost feeding days.
