Understanding "Peak Fixation" in Salmon Conservation
Every few years, headlines proclaim remarkable salmon comebacks across the West Coast.
These flashy reports create momentary optimism but conceal a more troubling pattern.
Peak fixation is our natural tendency to focus on amazing or unusually good years while overlooking the worsening low points and accelerating long-term decline. This cognitive bias leads us to see one great season as a sign that "things are getting better," even when decades of data show populations spiralling downward.
The Gambler's Mindset in Resource Management
This pattern of thinking isn’t just found in fisheries management. It’s similar to how gamblers get caught up in their occasional wins while ignoring the many losses they face. In the same way, people involved in fisheries tend to focus on the few really good years and downplay the ongoing, long-term drop in fish populations.

The Gambler's Fallacy in Action
Researchers have found that both decision-makers and communities demonstrate an "intermittent reinforcement bias" - where rare good outcomes leave a stronger impression than frequent bad ones. This makes occasional salmon booms disproportionately influential in shaping policy and public perception.
This cognitive distortion creates a dangerous form of collective denial, where societies continue high-risk practices despite mounting evidence that they're losing the conservation gamble.
Natural Fluctuations vs. Deteriorating Averages
Salmon populations have always been dynamic, experiencing natural boom-and-bust cycles influenced by varying ocean conditions, river flows, and predator dynamics.
However, what sets the current situation apart is the alarming long-term trajectory: the peaks are becoming increasingly fleeting and less frequent, while the periods of decline plunge to unprecedented lows with each passing decade.
This troubling trend is evident on B.C.’s central coast, where sockeye populations have suffered a devastating 90 per cent decline over the past 70 years.
Fisheries and Oceans Canada (DFO) expressed “serious concerns” over Fraser River sockeye runs, which saw historically low returns of only 293,000 sockeye in 2019 and 2020, a stark contrast to the 20 to 40 million a century ago.
What's Causing Salmon Decline?
The diminishing numbers of wild salmon are not due to a single factor, but rather a complex interplay of environmental stressors and human impacts. Understanding these threats is crucial for effective conservation.
Mining Activities
Tsolum River: In the 1960s, the Mount Washington Copper Mining Co. operated in the Tsolum River watershed, extracting 940,000 tonnes of waste rock. This led to a dramatic decline in Coho salmon populations, from 15,000 in 1964 to just 14 by 1984.
Britannia Beach: Mining activities at Britannia Beach resulted in acid rock drainage, severely polluting Britannia Creek and Howe Sound. This contamination caused the death of approximately 4.5 million juvenile chum salmon from the Squamish Estuary.
Habitat Degradation
Urban development, agriculture, and industrialization have destroyed critical salmon habitats. Dams, pollution, and the loss of riparian vegetation affect vital spawning and rearing environments across BC and beyond.
Coquitlam River: The construction of the Coquitlam Lake dam has restricted salmon migration, leading to the near-extirpation of sockeye salmon in the river. Efforts to transport Coho salmon upstream are underway to mitigate this impact.
Ecstall River: Industrial logging in the Ecstall River watershed has degraded critical salmon habitat.
Fish Farming
Open-net pen fish farms pose a major threat, transmitting diseases like sea lice to wild salmon. Chemical and antibiotic use in these farms can also lead to widespread environmental contamination.
Clayoquot Sound: This UNESCO Biosphere Reserve hosts approximately 20 open-net pen salmon farms. These farms have been linked to disease outbreaks, including a significant die-off in 2019, and the spread of sea lice and pathogens to wild salmon populations .
Overfishing
Industrial trawling in British Columbia is responsible for catching and discarding tens of thousands of salmon each year, with almost all of these fish dying before they hit the ocean again. In the 2023/24 season alone, industrial groundfish trawl vessels caught an estimated 28,000 salmon.
This bycatch is not a rare event:
  • Over the last 15 years, more than 140,000 salmon have died as trawl bycatch, with Chinook consistently making up around 89–93% of that total.
Climate Change
Rising ocean and freshwater temperatures adversely affect salmon health, reduce oxygen levels, and facilitate disease spread, disrupting migration patterns and increasing mortality.
Isolated Peaks Don't Indicate Recovery
While occasional strong runs emerge, they mask a deeper decline.
Consider the projected 734,400 Early Stuart sockeye passing through the lower Fraser River in 2025, embarking on their grueling 1,200-kilometre journey. This run is anticipated to be the largest since 1997, boosted by cooler ocean conditions and the removal of fish farms.
These factors have contributed to productivity levels not seen since the 1970s, offering a hopeful sign for this salmon population.
However, this individual success doesn't reflect the whole picture. The estimated 3 million total Fraser sockeye expected this year falls far short of the historical 8 million average for this particular cycle line, illustrating how specific "peaks" can dangerously hide a broader, worrying trend.
How Shifting Baselines Feed the Cycle
The illusion of "peak fixation" is amplified by "shifting baseline syndrome." This cognitive bias means that each generation defines what's "normal" based on their own lived experience.
The term was coined by fisheries scientist Daniel Pauly in 1995. For salmon, the abundant runs of the past are gradually forgotten, and today's depleted populations become the new, accepted benchmark for a healthy ecosystem.
1
Generational Amnesia
Each new generation accepts a lower standard of natural abundance as the norm, losing awareness of previous ecological conditions.
2
Inflated "Peaks"
Against this lowered baseline, even minor increases in salmon returns are celebrated as significant recovery, despite remaining far below true historical levels.
3
Erosion of Urgency
The misperception of recovery diminishes the urgency for conservation efforts, perpetuating the long-term decline of salmon populations.
The Deadly Consequences of Complacency
Why does peak fixation matter? Because it breeds dangerous complacency among decision-makers, managers, and the public. Those unusual high years become justification for maintaining the status quo or delaying difficult conservation decisions.
Policy Paralysis
Regulators point to exceptional years as evidence that current management approaches are working, despite mounting evidence to the contrary.
Delayed Protection
Critical habitat designations and fishing restrictions get postponed after "good" years, even when long-term averages continue declining.
Resource Misallocation
Conservation funding follows peaks and troughs rather than addressing systemic problems, creating a boom-bust cycle in restoration efforts themselves.
Lessons from the Collapse of the Atlantic Northwest Cod Fishery
The collapse of the Canadian cod fishery in 1992 is a cautionary tale that mirrors the risks facing wild salmon runs today. It shows how peak fixation can lead to irreversible loss.
In the late 1970s and early 1980s, cod catches surged due to advanced trawlers and sonar. These peaks gave the illusion of abundance, masking long-term decline.
Policy Paralysis
  • Despite scientists warning of overfishing, Canadian regulators delayed quota cuts, influenced by recent high catches.
Delayed Protection
  • By the time a fishing moratorium was enacted in 1992, cod stocks had collapsed beyond recovery thresholds.
Resource Misallocation
  • During the cod boom, investments flowed into fleet expansion instead of stock rebuilding. When stocks collapsed, the infrastructure became obsolete.
Disaster in the Troughs
  • Successive poor years pushed cod below replacement levels; once spawning groups vanished, recovery became impossible.
How You Can Break Free from the Peak Fixation Trap
Focus on Long-Term Trends
When you see headlines about record salmon runs, don’t just focus on the one good year. Look at multi-year averages, historical data, and full stock reports to understand the bigger picture.

Strong single years can hide long-term declines, so tracking trends over time shows if populations are really improving. Use trusted sources like Pacific Salmon Commission, DFO assessments, and data from groups like Watershed Watch or Raincoast Conservation.
Demand Transparent Reporting
Urge local media and government to report salmon numbers with full context.

Insist they show data alongside long-term averages and historical baselines, not just short-term highs.

Without this, the public may become complacent and less supportive of needed conservation measures. For instance, write letters to editors or comment on press releases, requesting "multi-decade trend" graphs to accompany seasonal counts.
Support Independent Science
Support or volunteer with non-government research groups that study and publish independent analyses of fish populations.
These independent organizations are critical for counterbalancing overly optimistic official messaging and maintaining necessary pressure on management agencies to take action.
Engage in Public Decision-Making
Participate in fisheries management meetings, habitat planning sessions, and public hearings related to water use and development projects.
Share your concerns and ask officials how they are managing the risks of low fish years, not just the good ones. Informed and consistent public scrutiny makes decision-makers less likely to delay critical conservation actions.
Watch the Budget
Monitor how conservation money is spent each year. Advocate for steady funding for habitat restoration and monitoring, even after "good" salmon runs.
When funding jumps up after bad years but drops after good ones, it creates an unstable cycle - just like the problem in managing fisheries.
Hold Public Officials Accountable
After strong salmon years, follow up with elected officials about their plans to protect fish during the low years that follow.
Request the public release of escapement targets and consistent reporting on whether these targets are met over multiple years.
Vote for candidates who demonstrate a commitment to science-based fisheries management. When officials know the public is paying attention to both the highs and lows, they’re less likely to ignore long-term problems.
The Path Forward: From Peaks to Sustainable Populations
True salmon stock recovery requires looking beyond the spectacular but misleading peaks to address the fundamental factors driving long-term decline: habitat degradation, water management issues, over-harvesting during vulnerable periods, and climate-driven ocean changes.
The time for complacency based on occasional good news is over.
