Fishing gear accounts for roughly 10% of that debris:
between 500,000 to 1 million tons
of fishing gear are discarded or lost in the ocean every year. Discarded nets, lines, and ropes now make up about 46% of the Great Pacific Garbage Patch.
How many fishing nets are lost each year?
Recent figures from the WWF indicate that
between 500 000 and one million tons
of ghost fishing equipment are abandoned in the ocean each year. Ghost nets are lost, abandoned or discarded fishing gear left by fishermen.
What is the percentage of fishing nets in the ocean?
Approximately
46%
of the 79 thousand tons of ocean plastic in the Great Pacific Garbage Patch is made up of fishing nets, some as large as football fields, according to the study published in March 2018 in Scientific Reports, which shocked the researchers themselves who expected the percentage to be closer to 20%.

Why are fishing nets left in the ocean?
Ghost nets don’t only catch fish; they also entangle sea turtles, dolphins and porpoises, birds, sharks, seals, and more. These animals swim into nets, often unable to detect them by sight or sonar.
The nets keep animals from moving freely, cause injuries, and keep mammals and birds from rising to the surface for air
.
Are fishing nets killing marine life?
Nylon is plastic and it does not decompose. That means that fishing nets lost in the ocean, called ghost nets, continue to catch fish for many years. Because of this,
hundreds of millions of marine animals are killed or injured every year due to fishing nets pollution
.
How many animals are killed by fishing nets?
More than 650,000

How much waste is at the bottom of the ocean?

20% to 30%
comes from marine sources such as fishing nets, lines, ropes, and abandoned vessels.
Where is ghost fishing a problem?
Here’s how we can tackle it. A team of “ghostbusters” is patrolling the waters of the

, in search of an underwater menace.
Why is fishing gear abandoned?
Gear is abandoned
when the fisher cannot retrieve it
, which happens when gear is snagged on reefs, rocks or other obstructions. Gear is considered lost if a fisher cannot locate it or has lost operational control over it.
