Fisherman repairing his net Fisherman repairing his net What are Ghost nets Ghost nets aren’t supernatural, but they are legitimately scary. A ghost net is a fishing net that’s been lost or abandoned in the ocean. They are one particularly egregious part of the global ghost fishing problem, which includes fishing gear abandoned in the water. Any net or line left in the ocean can pose a threat to marine life. Just because a net is no longer used by fishers doesn’t mean it stops working. These nets continue to trap everything in their path, presenting a major problem for the health of our oceans and marine life. Source: World Wild Life
