The Straight of Magellan in Chilean Patagonia (or Magallanes, as it’s known in Spanish) hosts the largest number of natural protected areas in the country. Permanent snow feeds the idyllic landscape, which has been shaped by glaciers, lakes, rivers and seas. Within its bounds live protected species—blue whales, sperm whales, Magellanic penguins, elephant seals, leatherback turtles, and southern and Chilean dolphins.
The cold waters of this far corner of the world are pristine; this makes them more sensitive to high-impact human activities. And now they’re being stressed by the arrival of salmon farms, which have already caused severe environmental damage in regions further north.
In Chile, the salmon industry uses harmful techniques and operates without proper regulation. Its rapid growth has overwhelmed coastal waters, filling them with huge amounts of antibiotics, chemicals, and salmon feces. These pollutants have led to partial or, in some places, complete lack of oxygen in the water, threating all forms of marine life.
Large salmon farms in the Magallanes region are already causing big damage. According to a government audit, more than half of the salmon farms operating there are affecting the availability of oxygen in the water, a condition that did not occur prior to their arrival.

Calling on Chile to stop salmon industry’s impact on Patagonia
AIDA alerted six international treaties to the damages the salmon industry is causing to Chilean Patagonia, and requested that they visit the Magallanes region to investigate the impacts and urge the Chilean government to protect the region. Santiago, Chile. In an Urgent Alert to international authorities, the Interamerican Association of Environmental Defense (AIDA) requested that experts visit the Magallanes region of Chilean Patagonia—where the expansion of the salmon industry is causing serious environmental damage—and asked them to urge the government to adopt appropriate measures to address them. “These six treaties were signed and ratified by Chile to protect its natural wealth, including the endemic species of the Magallanes region,” said Florencia Ortuzar, AIDA attorney. “The government is violating these agreements by failing to prevent the salmon industry from damaging the country’s marine environments.” The document details the principal damages caused by the salmon farms in Magallanes, among them: contamination of the seabed from large amounts of fish feces, excess chemical waste, and the over-saturation of waters with fish, all of which create oxygen-free dead zones where marine life cannot survive. The alert was sent to authorities in charge of the Convention on Biological Diversity, the Convention on the Conservation of Migratory Species of Wild Animals, the International Whaling Commission, the Inter-American Convention for the Protection and Conservation of Sea Turtles, the United Nations Convention on the Law of the Sea, and the Antarctic Treaty. The situation was also reported to the Food and Agriculture Organization of the United Nations and the World Health Organization. The Magallanes region is home to many protected species, including the blue whale, the sperm whale, the Magellanic penguin, the elephant seal, the leatherback turtle, the Southern dolphin and the Chilean dolphin. A remote and pristine area, Magallanes is poorly studied and it is thus virtually impossible to understand the consequences of the industry’s current and potential impacts. “More than half the farms operating in Magallanes are causing a total or partial lack of oxygen in the waters,” explained Ortuzar. “This demonstrates that the salmon concessions are being granted without the scientific support needed to guarantee they won’t cause environmental damage.” Another problem raised in the alert is the excessive use of antibiotics in Chilean salmon farms—higher than that of any other salmon-producing nation. This excessive use provokes antimicrobial resistance in humans, a problem that has been recognized by the World Health Organization as a serious threat to global public health. In the alert, AIDA requested the international authorities: support the Chilean State in the investigation of the salmon industry’s real and potential impacts on Patagonia; remind Chile of its obligations under the treaties; investigate the damage described; and, when needed, request the application of sanctions and the suspension or cancellation of concessions in Magallanes.

Opening our eyes to the dangers of salmon farming in Chile
Recently, I went to dinner with some friends. Two of them ordered salmon. The dish was expensive because, although Chile is the world’s second largest producer, salmon is a non-native species and one of the most popular fish in the country. I respectfully asked my friends if they were aware of the toll commercial salmon production takes on our oceans. Their response was glib: “That’s an exaggeration,” they said. “I don’t think it’s that bad.” Unfortunately, I expected that response. The environmental dangers of salmon farming in Chile are largely hidden, but that doesn’t make them any less serious. An unsustainable industry On July 5, nearly 700,000 salmon escaped from their pens at a farm off of Huar Island in Patagonia’s Los Lagos region. The escape has revived public debate on the dangers of Chile’s salmon industry. Caused by damage the pens sustained during a storm, the escape could represent one of the largest environmental catastrophes since salmon farming began in Chile in the 1980’s. But what’s the bigger problem? As it turns out, it’s not just one problem — it’s many. The problems of salmon farming first became visible in 2007 when scientists recorded the first case of infectious salmon anemia, a lethal illness for the fish. Although the industry adopted new infrastructure and sanitary standards, the root of the problem remained unaddressed—the overpopulation of marine habitats, packed with more fish than they could support, was causing oxygen depletion and, eventually, oceanic dead zones. Those poor farming practices also led to the excessive use of antibiotics to treat illnesses and infections. Eventually, other problems arose—algae blooms, and the so-called red tides that have devastated the area’s marine life. The recent massive salmon escape has posed serious public health risks because the fish had been treated with excessive amounts of antibiotics, making them inapt for consumption by humans or other animals. But, despite warnings from the authorities in the days following the escape, fishermen in the area began capturing salmon and selling them at extremely low prices. As an invasive predator, the salmon also posted a threat to the ecosystem, since they are aggressive fish prone to devastating anything in their path, including native species. Greenpeace said the escape was equivalent to a plague of 140 million rats eating anything in their path. Although the company was required to re-capture at least 10 percent of the salmon, they failed to reach that goal, despite offering up to $11 per fish. The work was further complicated since salmon are prey to sea lions and other predators. All this has revealed a clear structural problem—the lack of government control and regulation of an unsustainable industry. The most recent escape, from a farm owned by Marine Harvest Company, is yet another example of how the entire industry is failing to comply with environmental standards. According to Chile’s National Fish Service, some 3.3 million salmon have escaped from different fisheries in the Los Lagos, Aysén and Magallanes regions in the last eight years. Urgent Measures If this malpractice continues, salmon farming could destroy Chile’s marine biodiversity. Other countries have taken drastic actions in response to cases similar to the one on Huar Island. In the United States, for example, Washington State decided to gradually eliminate salmon farms after 300 salmon escape from a hatchery there. At AIDA, we are working to protect Chilean Patagonia, the country’s most pristine region, into which the salmon industry continues to expand. In May 2017, we filed a complaint with the Chile’s Superintendent of the Environment asking they investigate the damages salmon farms are causing to the Magallanes region, and sanction the companies responsible. We also commissioned a scientific report demonstrating how susceptible the region is to the risks of salmon farming. Hopefully my compatriots will realize that we share a common interest in protecting our most pristine waters from the damages of salmon farming. Because at the end of the day, that bite of salmon may be more expensive than they think.

Salmon farms in Chilean Patagonia approved without adequate environmental evaluation
A study commissioned by the Interamerican Association for Environmental Defense found that more than half of the salmon farms currently operating in the Magallanes region of Southern Patagonia have generated a partial or total lack of oxygen in the water. Nine of those are located in naturally protected areas. Santiago, Chile. A recent study, commissioned by the Interamerican Association for Environmental Defense (AIDA), concluded that salmon farms located in the Magallanes region of southern Patagonia were authorized without the scientific assessments needed to ensure they would do no harm to marine life. “After twenty years of development in other regions, the salmon industry now seeks to expand to the country’s last virgin coasts, without the necessary precautions,” explained Gladys Martínez, senior attorney of AIDA’s Marine Program. “This study demonstrates that neither the companies nor that State have done enough to avoid in Magallanes the severe environmental damage already perpetuated in other regions of the country.” Chilean biologist Héctor Kol produced the report for AIDA, with the support of the Waitt Foundation, analyzing 261 salmon farm projects. Of them, a little less than half have already been authorized and the rest could receive their permits in the short- and medium-term. Of the 126 authorized projects, only 35 are currently in operation. The information produced on each project includes location maps and estimations of the amount of waste being discharged into the waters. The research shows that there are large differences in the quantity of waste that the government authorized for different subsectors of the same geographic areas, without any available explanation as to why. “This demonstrates a clear lack of scientific evaluation, necessary to guarantee the aquatic environment will be able to receive and process the authorized quantity of waste,” said Florencia Ortúzar, AIDA attorney. “More than half of the projects that are currently in operation have already generated a total or partial lack of oxygen in the waters, which seriously impacts marine life. In addition, at least nine of these oxygen-depriving projects are located in natural protected areas.” On May 22, 2017, AIDA filed a complaint before the Superintendency of the Environment requesting the investigation of damages caused by salmon farms in Magallanes, and the sanctioning of the companies responsible.
