You may have read these global headlines about salmon aquaculture. Below are our responses:
There are PCBs in farm-raised salmon.
Polychlorinated biphenyls (PCBs) are widespread environmental contaminants found in trace amounts throughout the global food chain. All salmon (wild or farmed, across all six species) contain less than 2% of the PCB exposure limits set by national health authorities. Since early studies more than 20 years ago, reductions in fish meal and fish oil in salmon feed have further lowered PCB levels in farm-raised salmon. Health authorities worldwide continue to recommend oily fish, including salmon, as part of a healthy diet. [1]
There are lower levels of healthy Omega 3 in farm-raised salmon.
Salmon is a rich dietary source of long-chain omega-3 fatty acids (EPA and DHA). A typical 100 gram (3.5 ounce) serving of salmon provides 1800 mg of omega-3s, with 1–2 servings per week satisfying most dietary recommendations. Levels vary by species and by whether the fish is wild or farmed. Wild Atlantic salmon naturally have high omega-3 levels because they retain more of these healthy fats to support repeat spawning (Pacific salmon spawn only once). In farm-raised Atlantic salmon, omega-3 content reflects the amount of fish meal and oil in the feed, and these levels are routinely monitored to ensure they remain within expected ranges. [2]
Wherever salmon farms are, wild salmon vanish.
There is no scientific evidence that salmon farms cause the disappearance of wild salmon. Declines in wild populations have been linked to multiple pressures, including overfishing, habitat loss, and large-scale ocean changes driven by climate change. In many regions, wild salmon numbers were already falling long before aquaculture was introduced. For example, Alaska’s salmon catches declined throughout the mid-20th century, prompting the launch of a major aquaculture program in 1974. In Scotland, returns of salmon and trout have been on the decline since the 1950s, a trend mirrored on the east and west coasts of the country (salmon farms do not operate on the east coast of Scotland).
In British Columbia, Canada, a comprehensive inquiry (Cohen Commission) into a record low return of Fraser River sockeye salmon in 2009 concluded that the primary factor was likely marine conditions that led to poor zooplankton production (food for sockeye). Furthermore, the $30m inquiry found that the data presented “did not show that salmon farms were having a significant impact on Fraser River sockeye”. [3]
Salmon fillets are ‘grey’ before they dye it.
Salmon flesh turns pink only when the fish eat foods rich in carotenoids – healthy antioxidants that are also responsible for the colour of other animals, like flamingos. Young salmon are not pink; they develop their colour as they begin consuming carotenoid-rich prey such as krill. Farm-raised salmon receive carotenoids in their feed once they move from freshwater hatcheries to sea pens, mirroring the natural dietary shift that occurs in the wild when young salmon migrate from rivers to the sea.
You may have also read these statements on the ‘Salmon Free Falklands’ Facebook page. Below are our responses:
These so-called salmon are pumped full of antibiotics and sprayed with chemicals.
No salmon farm “sprays” chemicals on their salmon. Modern salmon farming relies primarily on vaccines rather than antibiotics to keep fish healthy. In leading producing countries like Norway, antibiotic use has fallen by over 99% since the 1980s. Any treatments that are used require veterinary approval and strict withdrawal periods before being selected for the market. The Falkland Islands operation would follow best-practice protocols from day one.
The only people to profit in this, the shareholders and a few executives.
Aquaculture businesses create a wide range of local jobs – from fish technicians and biologists to divers, trades workers, and maritime specialists. After approximately seven years of operation, Unity Marine’s activities are expected to generate additional revenues of about £26 million for the Falkland Islands Government. Local businesses also benefit through supply chain opportunities including transport, fuel, food, and biological monitoring services.
Yes, that’s right, and it all [general farm effluent] gets discharged into the sea. No onshore industry or livestock farming would be allowed to do that.
Responsible salmon farming manages fish waste through careful site selection in areas with strong tidal flow, which naturally disperses and assimilates organic material. Farmers use underwater cameras to minimise feed waste, and independent biologists regularly monitor the ocean floor. Farms are also rotated and fallowed to allow natural regeneration. Regulatory limits for benthic biodiversity – to be created for the Falklands based on best international practice – will also provide enforceable standards.
For added context, livestock farming commonly returns organic waste to fields for fertilisation. From there, the hydrological cycle takes over, which includes runoff into local water bodies.
People stuffing themselves with fat fish full of pesticides and heavy metals.
Farm-raised Atlantic salmon is one of the most tested and regulated food products in the world. Salmon feed ingredients are carefully sourced and tested, and finished products must meet strict food safety standards in every export market. Salmon, both farmed and wild, is widely recommended by health authorities for its healthy nutritional profile that is a good source of omega-3 fatty acids and very low in unwanted contaminants (mercury etc). [1][2]
It’s an industry that can only survive with the help of corrupt politicians.
The Falkland Islands Government is undertaking a transparent, science-based decision-making process that will be open to public scrutiny. The global salmon farming industry is a commercially viable, multi-billion pound industry operating in democratic countries with strong regulatory frameworks, including Norway, Scotland, Canada, and Chile. The sector has also built strong global markets – farm-raised Atlantic salmon is the top consumer choice and leading food export in the United Kingdom. [4]
I don’t think there is a good example of environmentally responsible salmon farming in the world.
Norway, Scotland, and other leading producers have developed comprehensive regulatory frameworks refined over decades. These include strict environmental monitoring, fallowing requirements, biomass limits, and regular benthic surveys. Many operators also meet the high standards set by the Aquaculture Stewardship Council (ASC) – a certification scheme founded by the World Wildlife Foundation. The ASC programme is designed to minimise the environmental and social impacts of salmon farming, focusing on biodiversity protection, water quality, and responsible feed usage. [5]
While no industry is without challenges, the best-managed farms demonstrate that salmon aquaculture can operate within sustainable environmental boundaries. The Falkland Islands has the advantage of learning from 60 years of global experience.
These proposed fish farms will be on the shoreline of a lot of farmers. Their wildlife tourist spots would likely be destroyed and their industry lost which is a vital part of the rural community.
Site selection is a critical part of a proposed aquaculture business. Informed by an Environmental Impact Assessment (EIA) and stakeholder consultations, farms would be located in areas that avoid sensitive habitats and minimise visual impact. In Norway and Scotland for example, salmon farming coexists with thriving tourism industries. Careful planning and community consultation would be essential to ensure farming complements rather than conflicts with existing land use.
The harvesting, processing, and packaging of Falkland salmon would be outsourced to Chilean businesses and infrastructure. Once the fish leaves our waters it would be beyond the reach of the perfect regulatory regime that FIG will have effortlessly implemented at minimal public cost.
It is important that the scale of business matches the needs and capacities of the local infrastructure and workforce. The details of harvesting and processing arrangements would be determined as part of the business planning process, will include the input of the local service and supply chain, and subject to government oversight. These are legitimate planning considerations that the Environmental Impact Assessment (EIA) and business case will need to address transparently.
It would be too expensive for anyone locally to want to buy it! Just on principle I wouldn’t buy it!
Atlantic salmon is one of the most popular seafood products worldwide, with strong demand across international markets. While the primary market would be export, local availability could also be part of the plan. Consumer choice is always respected – the goal is to provide an option that benefits the broader economy.
These companies are all about money not conservation.
While profitability of any business is paramount to its sustainability, a successful aquaculture venture depends critically on a healthy marine environment. Given responsible aquaculture is an evergreen business, there is strong incentive for the sector to protect the environment where it operates – poor environmental conditions lead to poor fish health and poor business outcomes. Strict environmental regulations, independent monitoring, and transparent reporting ensure that conservation standards are maintained.
Our government would for years subsidising them. Then get nothing because these clever operators will claim everything against tax.
The financial terms of any aquaculture licence would be set by the Falkland Islands Government (FIG) to ensure a fair return to the public. Unity Marine’s business activities are projected to generate approximately £26 million in additional government revenue after about seven years of operation. Tax arrangements, licence fees, and other fiscal terms are within FIG’s control to negotiate and enforce.
Capital allowances are a widely accepted feature of modern tax systems globally, designed to encourage investment by allowing businesses to offset qualifying capital expenditure against taxable profits. This is particularly relevant in sectors where upfront costs are substantial, such as oil and gas and commercial fishing. By easing the tax burden associated with major capital outlay, capital allowances play an important role in stimulating growth, productivity, and economic development, and is an important part of enabling economic diversification. [6]
You’re catching 3–4 kilos of fish to create 1 kilo of salmon.
This may have been true over a decade ago, but modern fish feed formulas have changed significantly. Today, most salmon feeds contain less than 25% raw marine ingredients and are predominantly plant-based and utilise fish trimmings from other fisheries that would have otherwise been discarded. Current feed conversion (feed turned into meat) means it can take less than one kilogram of wild fish to produce one kilogram of salmon, making farm-raised Atlantic salmon a net producer of fish protein. Unity Marine will commit to the Aquaculture Stewardship Council’s certification standards, that include responsible feed use, sourcing and traceability. [7]
It would be like building a city for half a million people and dumping all the effluent right here, completely untreated.
This comparison is misleading. Salmon farm waste is organic material – primarily fish faeces and uneaten feed – which is dispersed by tidal currents and naturally assimilated by the marine environment. Careful site selection in areas with strong water flow, combined with feed management using underwater cameras and regular seabed monitoring, ensures the environmental footprint is managed within strict and science-based regulatory limits.
The ocean is dead in the area where this massive industrial complex is happening.
Well-managed salmon farms do not cause ecological dead zones. Environmental monitoring in leading producing countries shows that properly sited and managed farms maintain healthy benthic (ocean bottom) conditions. Regulatory requirements for fallowing, site rotation, and biodiversity monitoring are specifically designed to prevent this. A full Environmental Impact Assessment (EIA) would establish appropriate criteria for the Falkland Islands Government to create and enforce science-based standards that protect the ecosystem.
Washington state in the US has now banned salmon farming because it has been proven to be disastrous to indigenous people.
It is true that a Washington politician phased out net-pen Atlantic salmon farming in the state despite the Washington Department of Fish & Wildlife concluding that there is “no evidence to date that Atlantic salmon pose a threat to native fish stocks in Washington”. [8]
Ron Allen, CEO and chairman of the Jamestown S’Klallam Indigenous Tribe condemned the political decision, saying: “Modern, well-regulated aquaculture is the environmentally responsible solution for producing seafood and exercising our Tribal treaty rights — now and into the future.” [9]
