Norwegian farms use AI robots with lasers to fight parasites

A network of 3,500 underwater robots equipped with computer vision systems and lasers has been deployed at Norwegian salmon farms. The devices, developed by Stingray Marine Solutions, are designed to eliminate sea lice that parasitize the fish.

The system uses machine learning algorithms to identify parasites on the salmon's body in real time. Once a target is detected, the robot directs a precise laser beam that neutralizes the louse without harming the fish itself. Using this technology allows farms to move away from harsh chemical baths, which were previously the primary method for controlling infestations.

The implementation of automated systems was a response to environmental requirements and the need to reduce fish mortality. According to the developers, the laser's targeting precision allows for the effective cleaning of the salmon population without the stress to the animals associated with catching and mechanical handling. The robots operate autonomously, patrolling the pens 24 hours a day.

For the aquaculture industry, this solution represents a shift toward precision management of biological risks. The use of autonomous AI agents in complex underwater environments demonstrates the ability to scale computer vision beyond standard IT tasks, providing a direct economic benefit by preserving the marketability and health of the fish.
