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.

Cetaceans and salmon farming: Challenges for the conservation of marine biodiversity in Chilean Patagonia (executive summary)
In 2018, the environmental organizations Interamerican Association for Environmental Defense (AIDA), Greenpeace, and the NGO FIMA joined forces to confront the threat of the expansion of salmon farming in the southern waters of Chilean Patagonia. Since then, we have been actively working to expose and stop the impacts of intensive salmon production in pristine ecosystems, including special protected areas. In 2021, a scientific study of whale-ship interactions in Chilean Patagonia was published, including a video of a blue whale navigating a high-traffic area. According to the study, the world’s largest and most endangered mammal shares space with up to 870 vessels daily in Chilean Patagonia, one of its main feeding grounds. The study confirmed that 83% of the vessels were involved in the aquaculture industry.This finding shed light on a new facet of the environmental issues facing Chilean Patagonia, home to nearly 30% of the world’s cetacean species, including the endemic Chilean dolphin. This led us to commission a scientific report from a multidisciplinary team of experts to make the information publicly available. The results provided evidence of the impacts of salmon farming on cetaceans in Chilean Patagonia and highlighted the lack of studies and information needed to understand the magnitude and consequences of these impacts, as well as the true risk involved.In addition to complementing the efforts of civil society to demonstrate the urgency of halting the expansion of salmon farming in the country’s southern seas, we hope that this report will specifically draw attention to the real and potentially irreversible problem affecting these emblematic species. We also hope that the report’s recommendations will encourage the development of conservation measures for cetaceans, even in a context of insufficient knowledge, in accordance with the Precautionary Principle — recognized in the General Fisheries and Aquaculture Law, national legislation, and international law — which establishes the obligation to act in favor of environmental protection, even in the face of uncertainty. Finally, we hope that this report will motivate further research necessary to implement concrete and effective protective measures to make our waters a safe space for whales and dolphinsRead and download the executive summary

Whales and salmon farming: how does the industry impact our gentle marine giants?
Chile is by nature a country of marine mammals. Of the 94 species of cetaceans existing in the world, 43 have their habitat in the country's waters. And just over a quarter of them are found in Patagonia. But Chile is also a country of salmon, occupying the second place in the world production, surpassed only by Norway. The overlap of the salmon industry with the habitat of these emblematic marine mammals represents a significant threat to cetaceans in Chile about which not enough is known.The recent deaths of three whales in protected areas of Chile's southern seas force us to ask ourselves why they are dying and how they are affected by the growing industry with which they share their habitat.Civil society is responding. In early November 2024, Greenpeace - together with the Kawésqar community Grupos Familiares Nómadas del Mar and with the support of AIDA - filed two criminal complaints against those responsible for the deaths of humpback whales in protected areas.These lawsuits, which have already been declared admissible, represent an unprecedented milestone in the country's criminal history, as they are the first take advantage of the amendaments made to the Penal Code by Law 21,595 on Economic and Environmental Crimes to the Penal Code to file a lawsuit for possible violations committed inside protected areas.In this context, AIDA, together with Greenpeace and the NGO FIMA - historical allies in the resistance to the expansion of salmon farming in the waters of Chilean Patagonia - commissioned a scientific report entitle “Cetaceans and Salmon Farming: Challenges for the Protection of Marine Biodiversity in Chilean Patagonia.”The report is currently available in Spanish, which lays out the available information on the impacts of salmon farming on the whales and dolphins of Chilean Patagonia. The results are alarming: serious risks have been identified, in addition to a lack of data that makes it difficult to understand the magnitude and consequences of the threats.One of the most evident impacts is the incidental capture of small and large cetaceans in farming centers. There are documented cases of entanglement and deaths, although the lack of official records makes it difficult to measure the severity of the problem.Another significant threat is the Intense maritime traffic in Patagonia, largely related to the salmon industry. Although there is no official data in Chile, there is evidence of deaths and serious injuries due to collisions between boats and whales. In addition, underwater noise from boat engines affects the health and well-being of the whales and dolphins, which depend on sound for communication and orientation.In addition to these, there are other problems of the industry, whose effects on whales and dolphins have not been adequately studied, but which we should consider while the studies are being conducted. One of these is the escape of salmonids, which compete with native species for food resources and may carry diseases that could affect smaller cetaceans in particular by reducing the availability of prey that serve as food.Microplastic pollution, 40 percent of which comes from salmon farming centers, is another under-researched environmental concern in terms of its impact on cetaceans. And the excessive use of antibiotics in Chilean salmon farming, one of the highest rates in the world, could be having negative indirect effects on the ecosystems that support these marine mammals.Finally, one of the most significant environmental impacts of the salmon farming in Chilean Patagonia is the generation of hypoxia and anoxia due to the excess of organic matter in the farming centers, coming from salmon feces and uneaten food that falls to the seabed. The decomposition of this matter consumes the oxygen in the water, creating zones in the sea where life becomes difficult or impossible.We hope that this report will fill the information gap that has become uncomfortable and even untenable in light of recent whale deaths.With this evidence, even in a scenario of limited knowledge, we will be able to encourage a governmental response towards the rapid implementation of effective protection measures for whales and dolphins in Chilean waters.Chile is a country of cetaceans, and as their guardians, we must ensure that our waters are a safe space for their development and well-being.

The Kawésqar people and the defense of their "maritorio" in Chile
By Liliana Ávila and Cristina Lux* A little over a month ago, the community Kawésqar Grupos Familiares Nómades del Mar sent us a very special invitation. The appointment was near the sea, near their territory, or more precisely, near their "maritorio", a place of islands, islets and archipelagos. There, the borders between sea and land are blurred and the trees grow sideways, adapted to the strong winds. The maritorio is a concept and also a way of inhabiting and understanding the world. It evokes the image of "territory", but seen from and in the sea. As a concept, it emerged in the context of what is known as nisology, or the study of islands. The place we visited is located in the fjords of Magallanes, the southernmost region of Chile, about two hours from Punta Arenas, the regional capital. The Kawésqar people tell us that less than a century ago, this maritorio was their home. There, their grandfathers and grandmothers sailed among the fjords, built their canoes, fished and dived. They went into the icy sea without special neoprene suits, protected with sea lion oil, and there they learned the secrets that its depths held. In the midst of fjords, winds and intense climates, these people developed their own systems of thought and life. But the lives of the Kawésqar have changed radically in recent decades. They tell us so. The vast territory that previous generations inhabited for centuries is now enclosed. The process of eradication has been accompanied by the commercialization of the land, the creation of extensive pastures and, more recently, the development and expansion of the salmon farming industry. Industrial salmon production has serious and lasting impacts on marine ecosystems. The communities of Kawésqar are well aware of this. Salmon is an exotic and carnivorous species for Chile, raised in huge farms: hectares of cages in the sea. The introduction of exotic species (which threaten native species), the excessive use of antibiotics, salmon escapes, the generation of waste, the treatment of large quantities of dead salmon, the excessive discharge of organic matter into the sea, and the generation of anaerobic environments (total or partial loss of oxygen necessary for life to thrive) are just some of the impacts of salmon farming in Chile. These impacts not only accumulate in the waters and on the seabed, but also penetrate the lives of the Kawésqar communities. The maritorio that their grandfathers and grandmothers sailed is now a desecrated space. The processes of reconstructing their identity, the appropriation of sacred places and the rites that are part of their collective memory have been affected by the development of an industry that sees the sea only as a space of economic exploitation and not as the sacred place where, in the not so distant past, men and women developed their worldviews and ways of life. Despite everything, the Kawésqar are a living people who meet, who gather around the sea and discuss strategies to rebuild their cultural fabric. They also come together to honor their grandfathers and grandmothers, to activate the genetic memory that connects them to the sea, to dive into its waters and fight for a salmon-free sea and for a country that recognizes the cultural diversity that runs through its history. We also connect with the legacy of the Kawésqar. Swimming with people from the community in these seas that have been navigated for thousands of years allowed us to look out a window that blurs the present and shows us alternatives. A present that allows life and coexistence with the sea, its ecosystems and its balance. Their struggle— supported by AIDA, the NGO FIMA, Greenpeace and many other organizations— has borne fruit. It has highlighted the impact of salmon farming in Chile and the need to end our dependence on it. But the challenges are still enormous. Salmon farming continues to ravage the seas inside and outside protected areas, in the most remote areas of Patagonia, occupying spaces that were once shared by all the peoples and creatures that inhabited the territory. Meanwhile, the people of Kawésqar continue to travel through their territory —rewarded and lived in and from the sea— identifying and recomposing their history, swimming in the waters that surround them. They do not lose hope of returning to their sea; they to continue to exist in it. *Liliana Avila is coordinator of AIDA's Human Rights and Environment Program; Cristina Lux is an attorney with the Climate Program.
