Aqua Robotics enables safer, healthier fish farms with autonomous net cleaning
- Published 7 July 2022 and updated 21 September 2026. Aqua Robotics’ battery-powered HALO-Robot autonomously cleans fish-farm nets. A unit travels around the cage top while attached brushes move down the net’s inner and outer surfaces; the system operates continuously and charges itself. It is supplied with software, service and maintenance.
- Biofouling can restrict oxygen, promote parasites and disease, and kill fish. The page contrasts HALO with copper-oxide coatings and high-pressure cleaning, which can pollute ecosystems, stress fish, reduce appetite, damage nets, raise escape risk and require diesel vessels. HALO is said to use 98% less energy than mechanical cleaning and reduce about 30 tonnes of CO₂ per pen annually, with no copper release and little staff attention. It is sold as a pay-per-service offering at a cost comparable to conventional cleaning.
- The company says the system is in use at several large Norwegian farms and links the product to UN goals 2, 9 and 14.
