35.86 million salmon died abnormally over three years, only 21 of 213 farms were inspected, data concealment, drug residue violations, misallocation of public funds... An investigation from Scotland has punctured the glossy exterior of imported high-end salmon and revealed the underlying logic of aquaculture: "regulatory absence = consumption risk," affecting every consumer and aquaculture practitioner.
When you order sashimi at a Japanese restaurant, the server will most likely recommend "Scottish salmon"; when shopping for high-end seafood on fresh food platforms, labels like "Scottish origin" and "deep-sea cage farming" always attract attention; even many aquaculture practitioners treat Scottish salmon as the benchmark for "high-end imported seafood," bringing it into their stores and pushing it to the market.
In public perception, "Scottish salmon" equals high quality, safety, and freshness—after all, it is backed by the premium waters of the North Atlantic, has a long farming history, and is endorsed by a so-called "strict regulatory system."
But a latest investigation released by Animal Equality UK has completely shattered this illusion.
Investigation data shows that from 2023 to 2025, the number of abnormally dead farmed Scottish salmon reached 35,867,788—a figure equivalent to nearly 30% of Scotland's total annual salmon farming output, meaning that for every 10 farmed salmon, 3 died abnormally along the way.
Even more shocking is that during these three years, among Scotland's 213 operational farms nationwide, only 2 unannounced inspections were conducted, and the number of unannounced inspections in 2023 and 2025 was 0; the 20 worst farms, which cumulatively saw more than 10 million deaths over three years, had zero inspections and zero supervision throughout.
On one side is a shocking mortality rate, on the other is supervision that exists in name only; on one side are companies concealing data and violating regulations, on the other is the government publicly praising problematic companies for "excellent welfare standards" and granting huge amounts of public funds.
This farming crisis happening thousands of miles away has never been merely an overseas industry news story—it is transmitted directly along cold chains, trade, and processing chains to China's end market, affecting every consumer's table safety and every aquaculture practitioner's business judgment.
Today we will deeply break down three core questions: Has the regulatory failure of Scottish salmon rotted to the root or is it merely superficial? Behind the high mortality rate, what safety hazards are hidden that consumers cannot see? How should aquaculture practitioners and ordinary consumers avoid this "high-end trap"?
As a seafood professional/salmon enthusiast, have you also been misled by the "imported high-end" label? Have you encountered imported salmon that looks premium but is actually questionable? Welcome to leave a comment in the comment section, and let's break down the truth together.
I. 35.86 million deaths: not an accident, but the inevitable result of systemic loss of control
The high mortality rate of Scottish salmon is not an accidental result of a disease outbreak, but a systemic loss of control resulting from the superposition of three factors: "high-density farming + regulatory absence + bundled interests," and the real mortality data is severely underestimated.
When many people see "35.86 million deaths," their first reaction is "a disease outbreak"—but the fact is that during these three years, Scotland did not experience a large-scale, uncontrollable aquatic disease outbreak. The root cause of the high mortality rate is the industry's own distorted development and the complete absence of regulation.
First, we must clarify a basic logic of the aquaculture industry: salmon farming is high-density intensive farming and has extremely high requirements for water quality, dissolved oxygen, and biosecurity. Once density exceeds standards and management is improper, it is very easy to trigger disease and sea lice outbreaks, leading to large-scale deaths. And Scotland's salmon farming industry has long fallen into the strange cycle of "emphasizing output, neglecting management."
According to public data from the Scottish government, over the past five years, the average annual growth rate of Scottish salmon farming density was 12%, and the farming density of some cages even exceeded the industry's reasonable standard by 30%—the direct consequence of high density is deteriorating water quality, intensified fish stress responses, frequent disease and sea lice infestations, and rising deaths year by year.
More critically, the official statistics are only the "tip of the iceberg." Through Freedom of Information (FOI) requests, Animal Equality UK found that Scotland's current mortality statistics rules contain multiple deliberately avoided "legal loopholes," the purpose of which is to cover up the real chaos in the industry:
First, "active culling is not counted": when signs of disease appear at a farm, companies will actively cull large numbers of fish to prevent spread, but these culled fish are not included in "abnormal death" statistics; second, "transport deaths are not counted": the number of fry and adult fish that die during transport is not counted at all; third, "juvenile deaths are not counted": fry that die within 6 weeks after egg hatching and before entering the sea are not included in statistics; fourth, "cleaner fish are not counted": to remove sea lice from salmon, Scottish farms release large numbers of "cleaner fish" (such as wrasse), and the deaths of these cleaner fish have never been included in official statistics. Since 2020 alone, at least 7 million cleaner fish have died.
The most representative case is the Applecross hatchery in Wester Ross—this hatchery, praised by the Scottish government for "excellent fish health and welfare standards," has cumulatively seen more than 9 million salmon deaths since 2022, once culled 1.3 million fish in a single week, yet still received as much as 5 million pounds in public funding subsidies.
Even more ironic, the hatchery uses a so-called "most advanced recirculating aquaculture system (RAS)," claiming it can "achieve zero pollution and low mortality," but its actual mortality rate is more than twice the industry average.
High-density farming planted the hidden dangers, statistical loopholes covered the truth, and the reason all of this could continue for three years comes down to one core cause—the complete failure of the regulatory system and the bundled interests between regulators and farming companies. This is the root of the chaos in Scotland's salmon industry.
II. Regulatory failure: not "lack of capacity," but "deliberate absence"
The regulatory failure of Scottish salmon is by no means an objective problem of "insufficient manpower" or "insufficient technology," but a subjective and deliberate absence caused by "bundled interests + lack of responsibility + institutional loopholes." Regulatory agencies have long become the companies' "protective umbrella."
In the aquaculture industry, regulation is the last barrier to safeguarding the safety bottom line—whether domestically or overseas, a mature aquaculture industry cannot do without a regulatory system of "routine inspections + unannounced spot checks + severe punishment for violations." But Scotland's regulatory system has long existed in name only.
The body responsible for enforcing aquatic animal welfare in Scotland is the UK Animal and Plant Health Agency (APHA). Based on data obtained through FOI, we can clearly see this "embarrassing regulatory record": in 2023, the number of APHA unannounced inspections of Scottish salmon farms was 0; in 2024, only 2 unannounced inspections were carried out; in 2025, it returned to 0 again.
You should know that Scotland has a total of 213 operating farms, distributed across multiple sea areas, and in three years there were only 2 surprise inspections — equivalent to "each of 320 farms being inspected only once per year." Such an inspection frequency cannot play any regulatory role at all. Even more absurd is that over the three years, only 21 farms received any form of inspection, accounting for less than 10%; and the 20 worst farms, which cumulatively saw over 10 million fish deaths in three years, had zero inspections, zero penalties, and zero public disclosure throughout.
When asked to disclose the inspection reports of these farms, APHA directly refused, giving the reason that "disclosing the reports could cause significant harm to the companies, affecting their operations and reputation" — this reason is essentially "covering up for them." The regulatory agency had long since sided with the farming companies, rather than taking the perspective of consumers and industry health.
Even more thought-provoking is that APHA even admitted that it "does not have centralized annual surprise inspection data" — in other words, even the regulatory agency itself does not know how many surprise inspections were carried out each year, which farms were inspected, and what problems were found. This "laissez-faire" regulatory attitude directly led to the intensification of industry chaos.
In addition to the absence of inspections, loopholes in the regulatory system have given violating companies "an opening to exploit." Salmon farming regulation in Scotland adopts a model of "company self-reporting + regulatory spot checks," but self-reporting lacks an effective review mechanism, and companies can arbitrarily conceal death numbers, drug use, and discharge conditions; while the randomness of spot checks is extremely low, and there are no clear penalty standards for violations — even if violations are found, most are "verbal warnings" or "rectification within a deadline," and almost no company has its farming qualification revoked or is hit with a high fine for violations.
More critically, the Scottish salmon farming industry is a local pillar industry, contributing a large number of jobs and fiscal revenue, which has led to a "binding of interests" between the government and farming companies — in order to preserve the scale of the industry and stabilize fiscal revenue, the government deliberately loosens regulation; farming companies then use this "loose environment" to pursue maximum output while ignoring quality and safety.
Here is an analogy anyone in the seafood industry can understand: this is like certain domestic seafood markets where, despite the existence of illegal drug use and passing off inferior goods as superior, because local employment and tax revenue are involved, regulators "turn a blind eye," and in the end those harmed are still end consumers and the credibility of the entire industry.
The deliberate absence of regulation has trapped the Scottish salmon farming industry in a vicious cycle of "no cost for violations, no risk for fraud." And the risks brought by this vicious cycle never stay within Scotland's waters; they will be transmitted step by step along the trade chain to China's end market, affecting every consumer who buys imported salmon.
III. Transmission of Consumption Risks: The Salmon You Eat May Hide Hidden Dangers
The chaos at the Scottish salmon farming end will be transmitted to the end consumption link through three paths: "decline in meat quality + excessive drug residues + pollution accumulation." These hidden dangers cannot be distinguished by the naked eye of consumers, yet they concern health.
Many consumers have a misconception: "As long as the salmon looks fresh and has no off odor, it can be eaten with confidence"; many seafood practitioners also believe: "As long as the source is from a 'well-known place of origin,' there will be no problem." But the fact is that the consumption risks brought by the chaos at the Scottish salmon farming end are mostly "hidden" and simply cannot be distinguished by the naked eye.
The value of high-end seafood is never conferred by a "place-of-origin label," but by "safety, quality, and transparency." The chaos in the Scottish salmon industry has sounded an alarm for the global seafood industry: no matter how famous the place of origin or how long the history, once regulation is absent and interests are unbalanced, it will ultimately lose consumer trust and destroy the reputation of the entire industry.
For consumers, what we pursue is not a "high-end label," but "peace of mind when eating"; for seafood practitioners, what we pursue is not "short-term profit," but "long-term operation." Seeing the truth about Scottish salmon is not about denying imported seafood, but about learning to screen supply sources with a professional eye and hold the bottom line with a rigorous attitude.
In the seafood industry, it has always been "the honest win, the violators perish." In the future, only those companies and practitioners who value safety, adhere to standards, and are open and transparent can stand firm in the industry.
