A Fishing Aggregating Device is a form of illegal fishing gear which is made of a plastic jug, palm leaves, recreational fishing line, and a lead weight. FADs are the leading cause of plastic pollution because the cheap line can get swallowed by wildlife and they can become entangled. Some FADs can become ghost if the line breaks and most are made of old motor oil and antifreeze bottles which if swallowed can poison wildlife. Sea Shepherd plans to find and remove these before they can cause any harm.
