'Ghost nets': How lost and abandoned fishing gear is destroying marine wildlife | CBC News

The sight of an deserted fishing web trapping fish or strangling seals by no means comes as a shock for B.C. industrial diver Bourton Scott.

Scott’s day job is beneath the ocean’s floor, inspecting underwater constructions for various shoppers. However throughout almost each dive, he comes throughout misplaced or discarded fishing materials — or “ghost gear” — that’s nonetheless snaring wildlife.

“When a web’s misplaced, it regularly fishes — it would not cease fishing,” stated Scott. “[And] because the animals which might be caught aren’t being harvested or eliminated, it baits extra animals into the online.”

The result’s “an ongoing dying entice.”

It is unknown how a lot ghost gear is mendacity beneath the floor of B.C.’s coastal waters. The supplies can sit underwater for many years, even centuries, disrupting marine ecosystems and killing wildlife.

After years of witnessing the injury first-hand, Scott determined to launch a cleanup program along with his shut pal Gideon Jones.

It is known as the Emerald Sea Safety Society (ESPS), and the group’s effort to take away nets alongside the Gulf Islands — positioned between Vancouver Island and B.C.’s south coast — is featured in a brand new documentary known as Ghost Nets.

Seals trapped

In line with the safety society, an estimated 800,000 tonnes of ghost fishing gear makes its method into oceans around the globe every year. The nets, ropes and traps are sometimes misplaced in storms, snags or after they’re run over by different vessels.

Consultants say it is exhausting to quantify precisely how a lot of it makes its method into waters round coastal B.C. However annual work finished by the area’s Fisheries and Oceans Canada workers spotlight how vital the issue is.

Earlier this 12 months, workers recovered greater than 200 misplaced, deserted and unlawful crab traps in Boundary Bay close to White Rock. Crews launched greater than 1,200 dwell crabs again into the water.

Final fall, a extremely publicized ghost web misplaced contained in the Fraser River trapped a variety of seals.

South of the border, analysis has additionally been finished to make clear the difficulty. One examine checked out 870 ghost nets recovered off Washington state within the U.S. They contained greater than 32,000 marine animals, together with greater than 500 birds and mammals.

In line with Joel Baziuk, deputy director of the International Ghost Gear Initiative, ghost nets have a probably devastating affect on harvestable fish populations, catching wherever from 5 to 30 per cent of the whole accessible shares every year.

The fabric can also be a serious contributor to ocean plastic air pollution.

“As a lot as 47 to 70 per cent of all of the plastic within the ocean by weight is misplaced fishing gear,” stated Baziuk. “Most fishing gear today is plastic, so it contributes to that drawback as effectively. And if the numbers are proper … it is each bit as a lot an issue as the opposite plastic particles.”

Discovering an answer

Volunteer and non-profit teams just like the Emerald Sea Safety Society are shouldering a lot of the work eradicating nets from alongside the B.C. coast line. The group at the moment runs off a set of public donations and grants — members even pay out of pocket for some bills. Industrial fishers have chipped in, volunteering vessels to take away heavy netting.

“Fishers are a part of the answer,” stated Baziuk. “No fisher ever desires to lose their web, it prices them cash … It is clearly a really exhausting financial loss for fishers after they lose a web.”

The group not too long ago lower out half of a giant web exterior Pender Island that divers initially found within the 1970s. The removing has been ongoing for almost 10 years, spearheaded by the Washington-based Northwest Strait Basis.

Recovered web supplies will be recycled into new fibres to make swimwear and carpet tiles.

The Emerald Sea Safety Society hopes extra funding will trickle down from the federal authorities. The DFO has not too long ago signed a partnership with the International Ghost Gear Initiative to advertise clear waterways.

“The problem is certainly getting some consideration,” stated ESPS co-founder Gideon Jones. “We’d like to see that translated into usable funds that teams like us might apply for.”
