The nets pulled up from the sea have an appearance that says it all. Thick ropes, discolored floats, hard tangles of plastic and salt. They stay there for months, sometimes for years, and continue to do their work even when no one is looking for them anymore. This is why ghost gear weighs so heavily in stories of marine pollution: it floats, moves, gets entangled, captures animals, scrapes the seabed and leaves plastic in the water that is consumed very slowly. In the North Pacific, meanwhile, a project led by Hawaiʻi Pacific University has just surpassed a concrete threshold: over 185 thousand pounds of abandoned fishing gear, or approximately 84 metric tons, recovered in just over three years.
When the ghost gear remains in the sea it continues to fish alone
The definition is simple. Ghost gear is lost, abandoned or discarded fishing gear that remains in the marine environment. NOAA explains that these nets, lines, buoys, traps and cables continue to trap and kill marine wildlife, suffocate habitats and also become a navigational hazard. Inside the Great Pacific Garbage Patch, the large area of plastic accumulation that forms between California and Hawaii, a study published in Scientific Reports estimated at least 79 thousand tons of floating plastic distributed over approximately 1.6 million square kilometers, a surface area more than five times the size of Italy. In that mass, at least 46% was made up of fishing nets.
Here the detail matters more than the slogan. When a network is lost, the damage does not stop at the moment of dispersion. The synthetic material remains resistant, continues to move with currents, hooks onto reefs, drags sediment, disrupts coral life and traps fish, turtles, marine mammals and birds. It is a plastic that remains active. And it is precisely this material obstinacy that makes ghost gear one of the heaviest forms of marine waste.
The Hawaii project starts from the fishermen
The idea of the Bounty Project has a concreteness that is immediately understood: entrusting the recovery to those who are already at sea. The program, launched in November 2022 by Hawaiʻi Pacific University’s Center for Marine Debris Research, works with the Hawaiʻi Longline Association and the Division of Aquatic Resources of the Hawaii Department of Natural Resources. Eligible commercial fishermen receive compensation to recover gear lost during normal fishing activities. Thus the material is intercepted in the water, before arriving on coasts, reefs and sensitive habitats.
The numbers help understand the scale of the project. The university reports more than 690 documented recovery operations, 77 commercial fishermen involved and over 2,100 hours of volunteer work. Among fishermen operating outside the longline system, 76% of identified material is removed within one hour and 88% within twelve hours. The project also includes monthly monitoring of sensitive reef areas, including Kāneʻohe Bay, specifically to intervene quickly when a net runs aground and begins to drag on the seabed. HPU adds a fact that gives a measure of the rarity of this work: the Bounty Project is one of only three known interventions that remove debris in the remote part of the North Pacific Garbage Patch.
There is also another aspect, more practical and less told. Using fishing vessels that already go out for work reduces the need for dedicated shipments and lowers emissions related to recovery operations. NOAA, which supported the initiative with 2022 funding along with additional support from Ocean Conservancy, describes this very formula as an efficient way to increase environmental benefits and accelerate offshore removals.
Once brought back to earth, the ghost gear enters the most inconvenient part of the matter: management. In social posts this phase is compressed into three reassuring words, often “reuse”, “recycling”, “disposal”. The HPU documentation tells a more concrete situation. In fact, most of the recovered material follows the Hawaiian path called Nets-to-Energy: the nets are shredded and sent to H-Power, where they end up incinerated with the production of electricity. A smaller share takes other paths. 2,323 pounds of recovered material was shredded and used in a Hawaii Department of Transportation experimental asphalt project called Nets-to-Roads at ʻEwa Beach. Another part remains stored for further recycling tests.
This is where the project gains real depth. Recovery at sea prevents those nets from continuing to work against the ocean. Onshore management, on the other hand, opens up an industrial, energy and logistical problem that remains entirely on the table. The Pacific remains huge. Meanwhile, 84 tons of nets have stopped holding corals, fins and carapaces.
