Ghost gear is fishing gear that has been abandoned, lost, or otherwise discarded at sea. Ghost fishing is what happens when some of that unattended gear continues to catch, trap, or entangle wildlife. The object and the process are related but not identical: not every lost item keeps fishing, while nets, traps, pots, and lines that retain their catching function can remain dangerous.
The most effective response begins before gear is lost. Design, identification, maintenance, reporting, professional retrieval, and port reception all address different points in the gear’s life cycle. A beach cleanup alone cannot prevent losses that occur offshore.
Why can unattended gear keep catching animals?
Modern fishing gear is designed to withstand water, tension, abrasion, and repeated use. Those same durable properties can allow it to remain functional after it separates from a vessel or fixed location.
- Nets can continue to entangle fish, marine mammals, turtles, and seabirds as they drift or snag on the bottom.
- Traps and pots may keep admitting animals that cannot escape. Dead animals can become bait that attracts more animals, creating a repeated capture cycle.
- Lines and ropes can wrap around animals, propellers, reefs, or other structures even when they no longer catch a target species.
How long a particular item remains hazardous depends on its material, design, location, depth, currents, storms, fouling, and physical damage. There is no single lifespan that applies to every type of ghost gear.
Why fishing gear becomes lost or abandoned
Gear enters the ocean through several routes, and each calls for a different prevention strategy:
- Severe weather: Storms and strong currents can move markers, break lines, or carry gear away.
- Snagging: Nets, lines, or traps may become caught on rocks, wrecks, reefs, or seafloor debris.
- Gear conflict: Mobile gear or vessel traffic can damage or sever fixed gear.
- Operational loss: Poor maintenance, inaccurate placement, mechanical failure, or handling mistakes can separate gear from its owner.
- Theft or deliberate disposal: Gear may be removed, abandoned, or dumped rather than brought ashore.
- Disposal barriers: Inadequate, inconvenient, or costly port reception can make responsible end-of-life handling harder.
It is therefore misleading to assume that all ghost gear was deliberately dumped. Good programs identify the local causes and match measures to them.
What harm occurs beyond continued catch?
The NOAA Ocean Service explanation of ghost fishing describes wildlife entanglement and capture as central impacts. Lost gear can also scrape or cover seabed habitats, damage corals and vegetation, obstruct navigation, foul propellers, and create hazards for working vessels and divers.
Fishers may lose equipment, catch, and time. Other crews may encounter gear they did not lose. Synthetic nets and lines can also fragment into smaller plastic pieces as sunlight, waves, and abrasion weaken them. These effects make ghost gear a wildlife, habitat, safety, and waste-management problem rather than only a litter issue.
A six-stage plan for reducing ghost fishing
| Stage | Primary responsibility | Useful measures | Evidence of progress |
|---|---|---|---|
| 1. Design and purchase | Manufacturers, buyers, fishers, and managers | Durable identification, appropriate marking, traceable components, and species-appropriate escape or weak-link features where required. | Gear can be identified, and safety features work under the intended fishery conditions. |
| 2. Use and maintain | Operators and vessel owners | Inspect lines, floats, fasteners, and electronic aids; plan for weather, depth, traffic, and gear conflict. | Losses, breakages, and conflicts are recorded and decline over time. |
| 3. Report a loss | Operator and designated authority | Promptly record position, time, gear type, quantity, markings, and any known hazard. | Reports are complete enough to support risk assessment and retrieval. |
| 4. Locate and assess | Authorized recovery teams and managers | Use reports, surface markers, electronic tracking, acoustic tools, surveys, or remotely operated systems as appropriate. | The team confirms location, ownership, wildlife, habitat, navigation, and retrieval risks. |
| 5. Recover safely | Trained, equipped, and authorized personnel | Choose a method that minimizes injury, bycatch, habitat damage, and risk to people. | Gear is removed without creating a greater safety or ecological hazard. |
| 6. Receive and dispose | Ports, waste operators, recycling programs, and managers | Provide accessible reception, sorting, reuse, recycling, or appropriate disposal. | Recovered and end-of-life gear has a documented destination and does not return to the water. |
How marking and tracking technology can help
Gear marking can connect equipment to an owner or fishery, support reporting, and help distinguish active gear from debris. Position records, GPS or satellite-linked surface devices, and acoustic location systems may help operators find displaced gear. Technology should support prevention and recovery, not replace maintenance, reporting, or reception facilities.
A 2016 FAO overview discussed markings, satellite and acoustic systems, and visible devices as tools being developed or used at that time. It is historical technology context, not proof that a device is now required, approved, or effective in every fishery. Current rules and equipment suitability must be checked for the relevant jurisdiction and gear type.
Why prevention and professional recovery must work together
Prevention usually avoids more harm and expense than finding gear after it has dispersed or sunk. Better placement, maintenance, identification, conflict planning, reporting, and affordable port reception can reduce the number of losses. Escape features or weak links may reduce continued catch or entanglement if gear is lost, but their design must match the fishery and regulatory setting.
Recovery is still needed for existing hazards. Yet removal is not automatically beneficial in every circumstance. Pulling embedded gear can damage sensitive habitat, and moving a trap or net with live animals can worsen injury. Ownership, navigation, contaminated materials, protected species, diver safety, and disposal all require assessment.
What should a member of the public do?
From a safe location, record the position, time, photographs, visible markings, gear type, and whether wildlife or navigation is involved. Report the finding to the appropriate local fisheries, marine-debris, coast guard, harbor, wildlife rescue, or emergency authority. The correct contact varies by place.
Do not enter the water, board unstable debris, pull heavy gear, approach a distressed animal, or cut lines from wildlife without trained direction. Entangling gear can tighten, shift suddenly, conceal hooks, or place both the person and animal at greater risk. If the item is on land and clearly safe to approach, follow local cleanup and disposal guidance rather than assuming it can be reused or discarded with household waste.
How to tell whether a program is working
Counting recovered gear is useful but incomplete. A successful program should also examine:
- the number and type of reported losses;
- the proportion of gear with usable identification;
- time from loss report to assessment or retrieval;
- wildlife entanglement or continued-catch evidence;
- recovery safety and habitat disturbance;
- the amount accepted, reused, recycled, or properly disposed of at ports; and
- whether the same loss causes recur.
These indicators separate a one-time cleanup from a system that prevents repeated losses.
The bottom line
Ghost gear is lost, abandoned, or discarded fishing equipment; ghost fishing is the continued capture or entanglement it can cause. Reducing the problem requires a full chain: safer and traceable design, careful use, rapid loss reporting, professional assessment and recovery, and convenient reception and disposal. The public’s safest role is observation and reporting, not hazardous retrieval.
