What changed
Stingray Marine Solutions, based in Oslo, Norway, has announced the deployment of over 3,500 AI-enhanced laser robots to protect salmon farms from sea lice. The company's latest annual report highlights that these robots are now operating in salmon pens along the Norwegian coast, protecting more than 112 million fish. The number of deployed units has increased by approximately 1,000 compared to the previous year.
What this means in practice
The AI laser robots use optical technology to target and eliminate sea lice, eliminating the need for harsh chemical baths that traditionally were used to control infestations. This method improves salmon growth and welfare while reducing mortality rates. The system operates continuously, 24/7, and is designed to avoid chemical use, which can harm the environment and lead to resistance in lice populations. The robots are deployed within salmon pens, allowing them to target lice effectively as fish move naturally within their environment.
Limitations and availability
The Stingray AI laser system is currently limited in range, as it is deployed within the confines of salmon pens. This means lice in darker or murkier areas outside the patrol zone may not be targeted. Additionally, the upfront costs of deployment may be a concern for some fish farming businesses. The system is best used as a preventative measure to keep localized lice populations low. The supplied announcement does not specify the exact cost or licensing conditions for the technology.
