An electric pulse could scare sharks away from fishing hooks

[Still Waters]

Electric pulse-emitting devices attached to baited hooks may scare sharks and rays away from fishing lines, new research suggests. This could dramatically decrease the number of sharks accidentally caught and killed by fishers who are targeting other species such as tuna.

An estimated 100 million sharks and rays are caught by fishers every year, resulting in more than a quarter of these species being threatened, per the World Wildlife Fund.

The device—called SharkGuard—takes advantage of sharks’ “sixth sense,” or their ability to detect electromagnetic fields using specialized organs around their nose and mouth called ampullae of Lorenzini. The technology was designed by engineering company Fishtek Marine.

but wouldn't it scare fish away too?
