Derelict fishing gear, sometimes referred to as “ghost gear,” is any discarded, lost, or abandoned, fishing gear in the marine environment.  

• This gear continues to fish and trap animals, entangle and potentially kill marine life, smother habitat, and act as a hazard to navigation.  
• Derelict fishing gear, such as nets or traps and pots, is one of the main types of debris impacting the marine environment today.
