Ghost fishing nets are one of the ocean’s quietest threats.
They may be lost or dumped by boats, but they keep “fishing” on their own, snagging fish, turtles, whales, and seabirds. Once an animal is caught, it can be hard or impossible to escape.
Norway is taking action on this.
A marine cleanup effort there is using underwater drones to find and map ghost nets. The drones can dive deep, scan the seafloor, and spot gear that would be easy to miss from the surface.
When a net is located, teams move in to remove it, using trained divers in some cases and robotic tools in others, then haul the debris up for disposal.
This matters because lost fishing gear can last for years. While it drifts or sits on reefs, it keeps trapping wildlife and can damage sensitive habitats like coral and sponge beds.
With drones doing the searching, the work becomes quicker and safer than relying on divers alone. The data also helps scientists see where nets tend to collect and how to reduce future losses.
It’s a solid example of using modern tools to tackle an old problem and give marine life a better shot.
