Glass Sponge Reef BC Salmon Farm Waste

Ancient Glass Sponge Reef Smothered By Salmon Farm Waste in B.C.

As Tavish Campbell dropped his remote camera into the water close to a salmon farm in the Broughton Archipelago, his heart sank.

Earlier in the day, during a dive, he was awestruck by the sight of an ancient, rare and previously undiscovered glass sponge reef in the water off Port Hardy, but now he was staring into the barren ruin of a second glass sponge reef.

“The one was totally alive and vibrant and healthy and the other one was a wasteland, covered in brown sediment,” Campbell told DeSmog Canada.

The live reef was at a depth of about 30 metres, which is unusually shallow for a glass sponge reef and Campbell did not drop a line into the water for fear of damaging the glass sponges.

“It was a little bit eerie doing the first dive, free-falling through the darkness and then my light illuminated this incredible sight — there were vibrant golden sponges, some standing two metres tall like giant vases. Schools of rockfish hovered over the top, there were king crab on top of the sponges and lingcod rested on the big egg masses with the males guarding the eggs. I was pretty gobsmacked,” Campbell said.

“I could hardly believe my eyes. It was like being on another planet. These sponges are ancient. These reefs have thrived there since the Jurassic (era) and were thought to have died off. It was like finding a herd of living dinosaurs.”

The euphoria of seeing the first reef, teeming with life, contrasted violently with the second site where the sponges were clearly dead and appeared to be smothered by waste and salmon feces from the farm, said Campbell, spokesman for Wild First, a coalition of organizations working to have salmon farms move from ocean pens to land-based operations by 2025.

“It was incredibly disheartening. . .One of my first thoughts was, with more than 130 salmon farms on the B.C. coast, what else is being smothered that we have yet to discover,” Campbell said.

“These sponges rely on clean water, free from excessive sedimentation, but unfortunately this is the exact opposite of the conditions under a salmon farm. With close to a million farmed salmon swimming overhead, the steady rain of feces and feed waste is a death sentence for life underneath.”

The fragile sponges, made of silica, were thought to have gone extinct 40-million years ago until living glass sponge reefs, estimated to be 9,000 years old, were discovered in Hecate Strait and Queen Charlotte Sound in 1987. Reefs were then found in Chatham Sound, Howe Sound and the Strait of Georgia

Both of the Broughton Archipelago reefs, about 1.6 kilometres apart, were discovered previously by Jody Eriksson and Campbell’s twin sister Farlyn Campbell, who were doing underwater surveys around open-net salmon farms, and Farlyn then asked her brother to film the area.*

Last year, Campbell filmed the startling “blood water” video showing a stream of blood pouring into the water off Campbell River from farmed salmon processed by the Browns Bay Packing Company. The video sparked an investigation by the province that found the effluent tested positive for the highly contagious piscine reovirus, a virus that can infect wild salmon.

The dead glass sponge reef was found under Cermaq Canada’s Cecil Island Farm and Cermaq managing director David Kiemele said the company is looking into the claims.

“All of our leases abide by strict environmental regulations about where we can locate farms to ensure we avoid known risks to sensitive marine habitats,” Kiemele said in an emailed statement.

The Cecil Island site has been empty since June 2017 and will remain empty for several more months, Kiemele said.

“The farm is what we refer to as a nursery site where only small fish are grown for short periods of time before being transferred to other farms, so it is not unusual for it to remain fallow for long periods of time,” he said.

Although Kiemele has seen the video, he said there is no way to “clearly understand where this video was shot, at a depth of more than 264 feet,” but that is now being investigated.

Campbell said it was not possible for the remote camera to go directly under the farm, so the video was shot from about six metres outside the perimeter.

The Canadian Parks and Wilderness Society has been working to protect glass sponge reefs in B.C. for decades and Ross Jameson, CPAWS-B.C. ocean conservation coordinator said the discovery is a wakeup call and demonstrates the need for the federal and provincial governments to work on protecting B.C.’s glass sponge reefs.

“The discovery of these glass sponge reefs is both incredibly exciting and saddening,” Jameson said.

“To find a new living reef is significant on a global scale. However, seeing the complete destruction of one of those reefs is devastating.”

Last year, the federal government established a 2,410 square kilometre marine conservation area in three sites between Vancouver Island and Haida Gwaii, restricting fishing in about 900 square kilometres.

The plan appears to be successful as there is a 150 metre buffer zone around the reefs to prevent them being damaged by sediment, Jameson said.

The reefs can be damaged by any bottom activity from shrimp fishing and dumping to trawling and more needs to be done by both the federal government and the provincial government, which has responsibility for the seafloor and salmon farm tenures, Jameson said.

Studies are being done on some of the reefs, but CPAWS wants an immediate precautionary approach around the sites so human activities do not destroy them while they are being studied, he said.

“There are about 130 fish farms on the B.C. coastline and we don’t know how many other glass sponge reefs are out there. There’s a good chance that there’s another one under an open net pen farm. We need to put some immediate protection in place,” Jameson said.

“With such limited restrictions on harmful activities along the coast, the discovery could just as easily have been two destroyed reefs,” he said.

Campbell also wants to see both levels of governments offer better protection for the reefs, especially as the province is looking at 22 fish farm tenures coming up for renewal in June.

Glass sponge reefs, which act as a giant ocean filter and essential habitat for marine life, are found only in B.C. and Alaska and, last December, the federal government added the Hecate Strait and Queen Charlotte Sound reefs to Canada’s tentative list for World Heritage Sites.

When those boxes of heavily redacted documents start to pile in, reporters at The Narwhal waste no time in looking for kernels of news that matter the most. Just ask our Prairies reporter Drew Anderson, who gleefully scanned through freedom of information files like a kid in a candy store, leading to pretty damning revelations in Alberta this spring. Long story short: the government wasn’t being forthright when it claimed its pause on new renewable energy projects wasn’t political. Just like that, our small team was again leading the charge on a pretty big story

In an oil-rich province like Alberta, that kind of reporting is crucial. But look at our investigative work on the Coastal GasLink pipeline to the west, or our Greenbelt reporting out in Ontario. They all highlight one thing: those with power over our shared natural world don’t want you to know how — or why — they call the shots. And we try to disrupt that.

Our journalism is powered by people just like you. We never take corporate ad dollars, or put this public-interest information behind a paywall. Here’s the thing: we need 300 new members to join this month to meet our budget.
