Salmon is the second most popular type of seafood in the U.S. (shrimp is the first), with just over 2 pounds consumed annually, per person.
While many love its flavor, a key reason behind its popularity has to do with its perceived health benefits. As a rich source of beneficial animal-based omega-3 fats, salmon can, indeed, be a very healthy food choice.
However, it can also be among the worst food choices, and the difference is in the details. While wild-caught Alaskan salmon is an example of good-for-you salmon, rich in healthy fats and low in pollutants, farm-raised salmon is not.
Unfortunately, farm-raised makes up 75 percent of the salmon consumed worldwide, and its volume has increased by nearly 1,000 percent from 1990 to 2015.
Two Dumpsters Full of Rotting Salmon Discovered at Fish Farm
The video below, captured by Don Staniford of Scottish Salmon Watch, shows dead salmon rotting in dumpsters at two Scottish salmon farms, one owned by Marine Harvest and the other by Scottish Salmon Company.
“This is symptomatic of factory farming — it’s the underbelly of battery factory salmon farming.
Infectious diseases are rife in the industry and about a fifth of a farmed salmon stock is dying.
The fish in these tanks are not going to shops but they have been swimming alongside ones that are,” Staniford said in a news release. “These fish are dying of horrible infections and diseases.”
It’s unclear how the fish in the video died, but salmon farms are required to store dead fish in a safe manner prior to disposal.
How many farmed salmon are dying every year in Scotland? According to Scottish Salmon Watch in a submission to the Scottish Parliament in March 2018, record levels of mortalities were uncovered in 2017 — 25,000 tons amounting to an estimated 15 million to 20 million farmed salmon, which is a mortality rate of 26.7 percent.
And mortalities appear to be on the rise, increasing from 5,000 tons in 2002 to 10,000 tons in 2011.
Farmed Salmon Could Pose ‘Irrecoverable Damage to the Environment’
Farmed salmon is Scotland’s biggest food export, bringing in more than $789 million annually, and the industry is set to expand from a volume of 163,000 tons in 2016 to 200,000 tons in 2020.
The industry claims aquaculture, as fish farming is known, is beneficial because it creates jobs while providing a sustainable source of food, but conservation groups and even government entities are finding otherwise.
The Scottish Parliament’s Environment, Climate Change, and Land Reform Committee issued a report in 2018 that found a host of concerning issues surrounding farmed salmon and concluded the industry could “cause irrecoverable damage to the environment” if said issues were not addressed. Some of the top issues covered in the report include:
Sea lice are marine parasites that attach to salmon skin, feeding on their skin and blood and leading to wounds that can be life-threatening.
Fish farms, with their large numbers of salmon living in close proximity, are ideal breeding grounds for sea lice, and there’s potential for lice on salmon farms to infect wild salmon, damaging their populations.
“Although conclusive evidence for damage at the population level is hard to find in Scotland, studies in Norway show that increasing sea lice burdens on wild salmonids adds to pressures on the wild populations already impacted by climate change, river modification, and commercial fishing,” the report noted.
While medications added to farmed salmon feed or water can help prevent sea lice buildup, they only represent a bandage — not a solution to the problem.
“Nearly all of these treatments are costly, none are fully effective, and most need to be repeated,” according to the review.
“In addition, sea lice populations also appear to be developing resistance to many existing treatment medicines and therapeutics.”
The Scottish Salmon Company has attempted to block the public release of photos showing their diseased salmon and even claimed losses of more than $1.3 million in 2016 because of sea lice and other diseases.
Despite this, they reported profits of over $38 million in 2017. Sea lice also represent a welfare issue for the fish, as the parasites can literally eat the salmon alive.
OneKind, an animal welfare group in Scotland, is calling for a halt on expansions to salmon farms until the sea lice issue and other welfare concerns are under control.
“It is now widely acknowledged that fish are sentient animals and are capable of feeling pain,” OneKind campaigner Sarah Moyes told The Ferret.
“Not only does this make this suffering wholly unacceptable, but the industry’s reputation is once again being damaged by another report of animal neglect.”
