Norway runs 2,000+ underwater AI laser robots delousing 50 million salmon

jjvincent · x · 2026-11-10

Norwegian company Stingray has deployed over 2,000 underwater AI laser robots that guard more than 50 million salmon and trout 24/7, zapping sea lice one at a time.

Context: sea lice are parasites that latch onto salmon — as few as 11 can kill a small fish, and one pen holds 150,000. The traditional fix of pumping fish out and blasting them with warm water is so rough that Norway's fish health report ranks it the top cause of death for adult farmed salmon. Stingray's robots instead hunt lice inside the pen all day using cameras and lasers.
