HARDANGERSFJORD, NORWAY – Jørgen Wengaard steers across the rocky islands of a fjord, his boat chopping throughout the water’s nonetheless floor, sending ripples towards silent forested shores. However right here within the Hardangersfjord of western Norway, nonetheless waters run deep: greater than 2,000 toes deep. “The Norwegian sea coast is very best for farming Atlantic salmon,” says Wengaard. “Now we have the optimum temperature. Now we have excellent oxygen ranges. Now we have the correct salinity and the water is at all times converting because of sturdy currents. That’s superb for farming.” Wengaard is headed to one of the crucial fjord’s a number of salmon farms, identified by way of their cylindrical pens constituted of nylon netting, some conserving masses of hundreds of salmon every beneath the outside of Hardangersfjord.
Norway is the arena’s greatest exporter of farmed salmon; greater than a 5th of salmon ate up by way of American citizens comes from the Nordic nation. And as Norway exports extra salmon internationally, the trade has come beneath complaint from environmental teams who say salmon farms are irreversibly impacting the pristine surroundings of Norway’s fjords. Wengaard’s boat glides to a prevent at a floating walkway surrounding two spaces of open water, round 50 toes in diameter, covered with vibrant yellow nylon netting: a salmon farm run by way of the corporate Lingalaks. Wengaard, who’s labored a lot of his existence on salmon farms, is a excursion information right here.

“That is moderately a small fish farm,” he says, mountaineering out of his boat. “Now we have two pens with simplest 15,000 salmon in every. That would possibly sound like so much, however on a regular-sized fish farm, they’ve a million salmon.” Above those open water pens, a mechanical arm swivels in position, taking pictures out pellets of meals. It activates silver streaks within the water under: a feeding frenzy. The pens are house for those Atlantic Salmon from March to December. In the ones 9 months, the fish develop to a weight between 10 and 15 kilos, after which they’re taken to a processing plant the place they’re shocked prior to they’re slaughtered, filleted and exported world wide.
However for now, they’re right here, consuming and swimming, the one factor keeping apart them from the open ocean is a skinny nylon web.
“We want to check up on it each unmarried day and search for holes, as a result of we truly are not looking for the salmon to flee,” says Wengaard, pointing to a tv display screen within the Lingalaks facility the place the corporate is in a position to track each the well being of the fish and whether or not the online conserving them is compromised by any means. “We are not looking for them to combine with the wild salmon,” continues Wengaard. “So even supposing those salmon come from wild salmon at the start, we are not looking for them to combine their genes and spoil the spawning puts for the wild salmon.” However in keeping with many trade professionals, it’s too overdue for that.

Masses of miles east of the fjords within the capital Oslo, creator Simen Saetre sits on a bench at his native park beside the raging waters of the Akerselva River, the place wild salmon, he says, can infrequently be observed, proper in the midst of Norway’s largest town. “I’ve by no means fished it myself, however infrequently you spot folks within the river they usually file great catches,” he says. Saetre, who co-authored The New Fish, a e-book about Norway’s salmon farming trade, says Norway’s wild salmon inhabitants has been reduce in part previously twenty years in large part because of the have an effect on of tens of thousands and thousands of farmed salmon. Each and every yr, a mean of 200,000 farmed salmon get away from their open web pens, a vital quantity whilst you believe that there are simplest an estimated 500,000 wild salmon left within the nation, says Saetre.
“Those farmed salmon then cross and swim as much as random rivers after which mate with wild salmon, they usually weaken the wild salmon inventory as a result of those farmed salmon, they’re made to be fats and gradual and be efficient for the trade,” says Saetre. “But if they mate with the wild salmon, the wild salmon offspring develop into gradual and fats and simple to catch for predators.” That’s a large reason why, says Saetre, why Norway’s wild salmon inventory is abruptly loss of life out. A learn about this yr by way of the Norwegian Institute for Nature Analysis and the Institute of Marine Analysis discovered that almost a 3rd of untamed salmon in Norway have “vital genetic adjustments” because of interbreeding with escaped farmed salmon. However Saetre says there’s a larger downside with Norway’s farmed salmon: sea lice. They’re tiny crustaceans that connect themselves to salmon, feed on them, and reproduce.
A pilot challenge run by way of the salmon farming corporate Eide Fjordbruck is a closed pen tank that holds 200,000 salmon. The closed pen protects the salmon from sea lice and stops the salmon within from escaping and interbreeding with wild salmon. The waste of the salmon is transported to a biogas tank, the place its used to make power.

“Those sea lice have lived for ages on wild salmon swimming by way of and hooked up to them,” says Saetre. “After which whilst you collect thousands and thousands of huge salmon within the fjords and the ocean lice get into that, it is like a heaven for the ocean lice, they usually develop and adapt.”
In a four-year learn about finishing in 2020, Norwegian scientists found out that within the fjords of western Norway mortality charges amongst farmed salmon from sea lice infestation reached greater than 30%. Salmon farms use chemical substances like insecticides to regard their fish, however scientists have found out that sea lice have advanced to develop into proof against the chemical substances. However one salmon farmer says he has a technique to a majority of these issues. In every other a part of the Hardangersfjord, Sondre Eide, the younger third-generation CEO of his circle of relatives salmon farming corporate Eide Fjordbruck, navigates his boat throughout the rain to what he calls his salmon farm of the long run. When he arrives, Eide issues to a black cylinder slightly protruding of the water, surrounded by way of floating gangplanks. It’s the cap of what seems to be a tank. “This tank is going down 72 meters. If it have been on land, it will be the absolute best construction at the west aspect of Norway,” Eide says. “It holds 200,000 fish.”

This, says Eide, is closed pen salmon farming: no escaped salmon and no salmon lice. “So it’s all about giving the optimum existence for the fish within,” explains Eide. “After which, after all, when you are taking away the salmon lice, you don’t have any salmon remedy, so that you shouldn’t have the dealing with, and that’s the reason accountable for 60 to 70% of all of the mortality within the trade. So then you’ll be able to focal point on how are we able to create the most efficient lives for the fish as a substitute of the following lice remedy.” Eide and a crew of his corporate’s engineers put years of labor and masses of thousands and thousands of bucks into this closed pen, which circulates ocean water into it and helps to keep lice out. It additionally filters out salmon waste – a large contributor to emerging nitrogen ranges within the fjords – by way of wearing it thru a sequence of tubes to a separate tank the place it in the end creates biogas which, in flip, can be utilized as power to energy this very facility, Eide’s subsequent challenge.
Eide’s closed loop farming gadget raises the query: Why isn’t all the trade farming salmon this fashion? Whilst Norway’s govt has been gradual to discover this new era, the federal government of Canada, every other primary salmon exporter, is phasing out open pens for its salmon farming trade to push corporations to construct pens like the only Eide has engineered. Eide says when he and his crew seemed for the era to perform this, it merely wasn’t there. He had the cash to check out and construct it, he says, so he did.
“For me, it was once the correct factor to do, and I 100% consider it from the ground of my center,” says Eide. “I do know my father would have carried out the similar lately. My grandfather would’ve have carried out the similar, too, as a result of instances exchange and we need to exchange with them.”

To underscore this push for sustainable salmon farming, Eide climbs again into his boat and navigates it towards a fair bolder challenge he’s constructed: the arena’s greatest floating artwork set up, only a 10-minute boat journey from his salmon farm. It’s a reflective silver orb that appears like a UFO that has crash-landed into the sea. Eide calls it the Salmon Eye, and as soon as our boat arrives to a dock hooked up to it, we input what seems like a swish lair of a James Bond villain, however what’s in truth an training middle about threats to the surroundings. Within, guests watch photographs projected at the partitions and ground whilst listening to tales about an atmosphere at risk prior to collaborating in a task play concerning the sustainability of salmon farming. After that, those that have controlled to safe a reservation for Eide’s Michelin-Starred eating place upstairs partake in an 18-course tasting menu of sustainable seafood. “We’d like 50% extra meals against 2050,” says Eide. “And we’ve used 50% of all useable land for meals manufacturing. And we’ve simplest used 2% of the energy coming from the sea, and but we all know much less concerning the ocean than we do about house.” And someplace in those huge, deep, our bodies of water, says Eide, lies the solution to feeding the arena sustainably.
