So-called “ghost gear”, fishing equipment which is lost in the sea, can continue killing marine life for decades or even centuries after it first enters the ocean, making it the most deadly form of marine plastic debris.
Why is ghost gear a problem?
Ghost gear impacts marine mammals, seabirds, sea turtles, and more, and is the type of debris that has proven to be the most lethal. In Mexico's Upper Gulf of California, for example, abandoned gillnets have contributed to driving the vaquita porpoise to the brink of extinction.
Does fishing gear pollute the ocean?
NEW RESEARCH: Fishing Gear Accounts for an Alarming Amount of Plastic Pollution in Oceans. More than 100 million pounds of plastic from industrial fishing gear pollute the oceans each year—threatening marine life.
What is the impact of ghost fishing?
Ghost fishing can impose a variety of harmful impacts, including: the ability to kill target and non-target organisms, including endangered and protected species; causing damage to underwater habitats such as coral reefs and benthic fauna; and contributing to marine pollution.
Is ghost fishing serious?
Ghost fishing gear is the deadliest form of marine plastic as it unselectively catches wildlife, entangling marine mammals, seabirds, sea turtles, and sharks, subjecting them to a slow and painful death through exhaustion and suffocation. Ghost fishing gear also damages critical marine habitats such as coral reefs.
42 related questions foundWhat is Ghost gear in the ocean?
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.
How do you prevent ghost gear?
Lost or abandoned fishing nets are often referred to as 'ghost gear. ' One possible solution to prevent the abandonment of fishing gear is to mark it with electronic and acoustic tags, which would presumably make it easier to recover, and easier to hold those who discarded it more accountable.
How does ghost fishing affect marine life?
Since hundreds of animals can be caught in a single net, you can see just how monumental this threat is. And ghost nets harm coral reefs too—breaking corals, exposing them to disease, and even blocking the reefs from needed sunlight. Ghost nets are also a major contributor to the ocean plastics crisis.
How does Ghost gear happen?
Ghost gear has many causes, but the primary ones are snags on rocks, reefs or spires beneath the surface of the water; conflict / entanglement with other deployed fishing gear; severe weather where gear must be abandoned for safety reasons; and gear being cut loose incidentally by other marine traffic crossing over top ...
Is ghost fishing a bycatch?
Neither bycatch nor ghost fishing are intentional actions, rather they are by-products of fishing. The most important difference between bycatch and ghost fishing is that one involves active fishing gear, and one does not.
How much ghost gear is in the ocean?
An estimated 640,000 tonnes of ghost gear enters the ocean every year, equivalent in weight to more than 50,000 double decker buses. It has been estimated that ghost gear constitutes 10% of the plastic waste in our oceans, but represents a much higher proportion of large plastics found floating at the surface.
What is the biggest polluter in the ocean?

What is ghost fishing gear?
“Ghost gear” is any fishing gear that is abandoned, lost or discarded in aquatic environments. This includes fishing nets, long lines, fish traps, lobster pots or any other human-made device used to catch aquatic animals.
How do ghost nets end up in the ocean?
Ghost nets are part of a larger problem: unsustainable fishing practices which add thousands of tonnes of plastic to the marine environment each year. These nets continue to float in the ocean's currents, entangling marine wildlife, damaging reefs, invisibly and silently killing.
What are the long term consequences of ghost fishing?
Ghost fishing can impose a variety of harmful impacts, including: killing target and non-target organisms, including endangered and protected species; causing damage to underwater habitats, such as coral reefs and benthic fauna; economic losses from target species mortalities and replacement costs; and contributing to ...
How does Ghost fishing occur?
Ghost fishing is what happens when old fishing gear is lost or abandoned at sea. It gets dragged around the ocean by currents and storms, killing fish and damaging marine habitats.
How many animals get caught in ghost nets?
Ghost fishing cycle. Each year, more than 100,000 whales, dolphins, seals and turtles get caught in nets, lines, traps and pots.
What is being done to stop ghost fishing?
While there are no quick-fix solutions, the United Nations has outlined practical measures aimed at curbing ghost gear, such as educating the fishing industry about the problem and providing incentives for fishermen to report lost equipment and retrieve nets they find at sea.
Is bottom trawling bad?
there is overwhelming scientific evidence that bottom trawling causes terrible damage to seafloor ecosystems and even more terrible damage to the fragile and slow growing ecosystems of the deep sea.
Why do fishermen dump nets?
In some cases, illegal fishermen may be deliberately dumping their nets into the ocean to avoid getting caught. But most legally operating fishing vessels simply lose their gear due to poor weather, or because nets collide with boat propellers, rocks or other fishing vessels.
