These animals swim into nets, often unable to detect them by sight or sonar. The nets keep animals from moving freely, cause injuries, and keep mammals and birds from rising to the surface for air.
Since hundreds of animals can be caught in a single net, you can see just how monumental this threat is. And ghost nets harm coral reefs too—breaking corals, exposing them to disease, and even blocking the reefs from needed sunlight. Ghost nets are also a major contributor to the ocean plastics crisis. Most modern nets are made of nylon or other plastic compounds that can last for centuries.
Our oceans are haunted by ghost nets: Why that's scary and what we can do
According to a study in Scientific Reports, ghost nets make up at least 46 percent of the Great Pacific Garbage Patch. Those abandoned fishing lines and nets that do breakdown never go away; they just become smaller pieces of plastic. Marine animals mistake this microplastic for food and eat it, which can harm internal organs, keep them from eating, and expose them to toxic chemicals.
Exorcising ghost nets from our oceans will require commitment, cooperation, and innovation. WWF is one of many groups working to remove ghost nets from the sea.
Our offices around the world are collaborating with local fishers and governments to identify target areas and remove as many nets as possible. In , a single WWF-led mission in the Baltic Sea hauled up tons of nets, ropes, and other material. We discuss the ecological impact of ghost nets, enjoy a safe survey dive, share our contributions, and together, make a difference to our oceans.

And they are not harmless: ghost gears kill marine life; with sharks, turtles, fish and birds dying from net entanglement, drowning, suffocation and other fatal injuries.
