What does ghost gear mean?

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.

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.

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.

What is ocean ghost gear?

One of the biggest threats to our oceans is marine litter and in particular, ghost fishing gear. The term ghost gear refers to any fishing gear that has been abandoned, lost or otherwise discarded (for example nets, line, rope, traps, pots, and floats).

How long does it take ghost gear to break down?

Some of the abandoned nets can be as big as football pitches, and this plastic-based ghost gear can take up to 600 years to break down, shedding microplastics as it degrades.

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 ...

Why is fishing gear abandoned?

The factors which cause fishing gear to be abandoned, lost or otherwise discarded are numerous and include: adverse weather; operational fishing factors including the cost of gear retrieval; gear conflicts; illegal, unregulated and unreported (IUU) fishing; vandalism/theft; and access to and cost and availability of ...

Is Ghost gear harmful to ocean life?

Ghost gear causes the loss of commercially valuable fish stocks; a fish lost to ghost gear is a fish that will never breed, be sold or eaten. This adds to the impacts of illegal and overfishing. In the Baltic Sea, a single lost gillnet can destroy US$20,000 worth of seafood.

How is the deep sea impacted by ghost gear?

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.

How does Ghost Gear affect marine life?

These 'ghost nets' impact not only local fisheries, but also result in by-catch of threatened and protected marine species. Many of these nets are washed up on northern Australia beaches, entangling numerous marine species including turtles and dugong which are of local cultural importance.

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 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.

Where do ghost nets come from?

Ghost nets aren't supernatural, but they are legitimately scary. A ghost net is a fishing net that's been lost or abandoned in the ocean. They are one particularly egregious part of the global ghost fishing problem, which includes fishing gear abandoned in the water.

How much plastic in ocean is fishing gear?

Fishing Gear Makes Up An Estimated 10% Of Ocean Plastic

Now, 10% is still a lot.

Why can't we use nets to simply scoop up the marine debris?

Cleaning up marine debris is not as easy as it sounds. Many microplastics are the same size as small sea animals, so nets designed to scoop up trash would catch these creatures as well. Even if we could design nets that would just catch garbage, the size of the oceans makes this job far too time-consuming to consider.

What are the other garbage patches around the world?

There are five gyres to be exact—the North Atlantic Gyre, the South Atlantic Gyre, the North Pacific Gyre, the South Pacific Gyre, and the Indian Ocean Gyre—that have a significant impact on the ocean. The big five help drive the so-called oceanic conveyor belt that helps circulate ocean waters around the globe.

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.

How much fishing gear is in the ocean?

An estimated 4.6 million fishing vessels ply ocean waters, setting fishing gear across every ocean basin. The research team focused initial analysis on industrial fisheries which operate large vessels and stay at sea for weeks and months at a time.

What is Aldfg?

Abandoned, lost or otherwise discarded fishing gear (ALDFG)

Is fishing worse than plastic?

The plastic pollution impact of fishing gear is definitely worse, as a whole, than that of plastic straws or bags. But it's not easy to calculate the precise impact of one individual action versus another.

What is the biggest polluter in the ocean?

They found that China and Indonesia are the top sources of plastic bottles, bags and other rubbish clogging up global sea lanes. Together, both nations account for more than a third of plastic detritus in global waters, according to a report in The Wall Street Journal.

What does Macroplastic mean?

The term macroplastics describes plastic items with a diameter ≥ 5 mm. With this size definition macroplastics can be directly distinguished from microplastics (diameter < 5 mm). Plastic items ≥ 5 mm are commonly considered to be macroplastics once they are released into the environment.

What is catch catch?

Bycatch (or by-catch), in the fishing industry, is a fish or other marine species that is caught unintentionally while fishing for specific species or sizes of wildlife.

How does ghost fishing occur?

Ghost fishing occurs when lost or discarded fishing gear that is no longer under a fisherman's control continues to trap and kill fish, crustaceans, marine mammals, sea turtles, and seabirds. Derelict fishing nets and traps can continue to ghost fish for years once they are lost under the water's surface.

Who is affected by ghost fishing?

However, it can be deadly for other marine life. Dolphins, whales, and turtles often get caught in the line, making it difficult for them to swim and feed. A report by NOAA found that seabirds are the most at risk from ghost fishing line, with around 10 times as many birds caught as turtles or mammals.
