Ghost Gear and Marine Rescue: What the Future Holds
Why ghost gear is still a ticking time‑bomb
Every year, an estimated 640,000 tonnes of abandoned, lost or discarded fishing gear (ALDFG) – known as “ghost gear” – slips into the world’s oceans (UNEP, 2023). This invisible threat continues to entangle seals, turtles, sharks and seabirds, undermining the work of rescue organisations such as British Divers Marine Life Rescue (BDMLR) and the RSPCA.
Emerging technologies that could end the nightmare
Biodegradable nets. Trials in the North Sea and off New Zealand have shown that nets made from polyhydroxyalkanoates (PHA) lose strength after 12‑18 months, turning into harmless organic matter. A 2024 study published in Marine Policy reported a 73% reduction in entanglement incidents when biodegradable gear replaced conventional nylon.
Smart acoustic tags. New low‑power tags now transmit a seal’s location every 10 minutes without hindering its natural behaviour. BDMLR plans to equip 150 rescued pups with these tags by 2025, enabling rapid response if they drift into high‑risk zones.
AI‑driven net‑detection drones. Companies like OceanX are piloting autonomous surface drones that scan the water for floating ghost gear using machine‑learning image recognition. Early field tests have identified an average of 35% more debris per hour than manual patrols.
Policy shifts that could accelerate change
European Union’s Ghost Gear Initiative proposes mandatory gear‑traceability systems and a 30% levy on lost‑gear insurance premiums. If adopted widely, these measures could fund large‑scale retrieval programmes and push manufacturers toward eco‑design.
Community‑led solutions gaining traction
Grass‑roots actions are proving that bottom‑up efforts matter. In Cornwall, volunteers from Aegean Rebreath removed 2.4 tonnes of ghost nets in just six months, restoring critical feeding grounds for local seal colonies.
Similarly, the Marine Stewardship Council now recognises fisheries that achieve a “Zero Lost Gear” certification, incentivising sustainable practices through market access.
Future scenario: a circular ocean economy
Imagine a world where every discarded line is collected, shredded, and transformed into high‑value products—such as marine‑grade composite panels for offshore wind farms. Start‑ups like Ocean Kind are already piloting this model, turning waste into profit and creating jobs in coastal communities.
Pro tip: How you can make a difference today
- Choose seafood certified by MSC or the Aquaculture Stewardship Council (ASC) – these labels require robust gear‑management standards.
- Replace single‑use plastic bags with reusable alternatives; less plastic on land means less chance of it ending up as ghost gear.
- Support NGOs that fund ghost‑gear retrieval by donating or volunteering for local clean‑ups.
FAQ – Quick Answers on Ghost Gear and Marine Rescue
- What is ghost gear?
- Any fishing equipment—nets, lines, traps—that has been lost, abandoned or discarded and continues to trap marine life.
- How does ghost gear affect seals?
- Entanglement restricts movement, leads to injuries, infection and often causes drowning, as seen in the tragic case of the rescued seal Carrom.
- Can biodegradable nets replace all traditional gear?
- They are suitable for many pelagic and demersal fisheries, but high‑strength applications (e.g., deep‑sea trawling) still rely on durable synthetics while research continues.
- Who funds ghost‑gear removal?
- Funding comes from government grants, EU schemes, fisheries’ levies, corporate CSR programs and charitable donations.
- How can consumers help?
- Buy responsibly sourced seafood, reduce plastic consumption, and support organisations that clean up marine debris.
