Norwegian tech company Harbor has taken a major step forward in protecting farmed salmon from harmful jellyfish, after trials confirmed the effectiveness of its electric barrier technology.

Harbor’s solution uses its existing Harbor Fence technology, an electric barrier that neutralises sea lice larvae and now shows promise in mitigating the impact of jellyfish. Recent trials demonstrated that a controlled electric shock triggers venom release in pearlside jellyfish, rendering them harmless for days and allowing them to drift through salmon farms without endangering fish.

“Millions of salmon die annually due to pearlside jellyfish, causing immense financial and welfare losses. Our technology offers an innovative solution, and industry interest is growing rapidly,” said Bernt Aage Lie, COO of Harbor, in a press release.

The Harbor Fence has already been deployed successfully at several aquaculture sites to combat sea lice, and its new application for jellyfish expands its potential impact. The breakthrough has sparked significant interest across the aquaculture sector and fuelled a highly successful share issue, oversubscribed by 30 percent.

Following the oversubscribed share issue, Harbor is preparing to scale production and meet rising demand from fish farmers eager to enhance fish health and reduce mortality rates.
