The Vital Role of Atlantic Salmon: A Keystone Species for Health and Ecosystems

Written By Kelly Mahony

Summary 

Atlantic salmon, a vital species for ecosystems, cultural traditions, and local economies, face critical threats from habitat loss, pollution, climate change, and unsustainable aquaculture practices. As a keystone species, they contribute to nutrient cycling, biodiversity, and clean water production, while also supporting fishing industries, eco-tourism, and green jobs in rural and Indigenous communities. However, their survival is increasingly jeopardized by habitat degradation from dams and urbanization, climate-induced disruptions to their life cycles, and aquaculture risks, such as disease spread and pollution. Despite these challenges, innovative conservation strategies, community-driven efforts, and policy interventions offer hope for recovery.

Successful conservation efforts demonstrate the potential for meaningful impact. The Penobscot River Restoration Project in Maine doubled adult salmon returns in five years by removing outdated dams and restoring critical habitats. Innovations like environmental DNA (eDNA) and GIS mapping have advanced salmon monitoring, while enforcement of policies such as the Endangered Species Act (ESA) reduce illegal fishing and funded habitat restoration. Opportunities for further conservation include dam removal, riparian reforestation, stream rehabilitation, and sustainable aquaculture practices, such as closed-containment systems paired with advanced monitoring technologies.

Stakeholders play a pivotal role in driving the recovery of Atlantic salmon populations. Policymakers can enhance aquaculture regulations, fund habitat restoration projects, and champion climate-resilient strategies. Conservation organizations are key in leading community-driven habitat restoration initiatives, advocating for global overfishing regulations, and raising public awareness about the importance of salmon conservation. Individuals and communities can make a difference by supporting sustainable seafood choices, volunteering for restoration efforts, and donating to nonprofits dedicated to protecting salmon habitats. By working together, stakeholders can ensure the survival of Atlantic salmon and the ecosystems they sustain, fostering a future where these species continue to thrive.

The Case for Atlantic Salmon Conservation 

Each year, as the first rains swell the rivers and awaken the rhythm of the seasons, Atlantic salmon begin their journey home. Guided by an unspoken bond to the waters of their birth, they travel vast distances, surging through tides and leaping against roaring waterfalls. Their migration is a testament to endurance, driven by a primal connection to the rivers that shaped them.

In these waters, salmon leave more than ripples; they bring life into the heart of the ecosystem. The rivers they ascend transform under their presence, enriched by the nutrients they carry from the sea. Trees grow stronger, aquatic plants flourish, and the land itself awakens, sustained by their contributions. When they reach their journey’s end, they offer everything back to the waters, ensuring that new life can emerge.

However, there are places where this ancient cycle falters, where the rivers run still, with the salmon’s return no longer guaranteed. On Maine’s Penobscot River, years of blocked migrations left these waters diminished. But when outdated dams were removed, the river reclaimed its purpose. The salmon came back, and with them, the life they carry. Today, their struggle and renewal remind us that these rivers—and the creatures that call them home—are part of a delicate balance that holds the world together.

The Atlantic salmon’s story is not just one of survival but of interconnectedness, resilience, and the enduring promise of nature when given the chance to restore itself. Their journey echoes a truth older than memory: the rivers and seas we protect are the lifeblood of the natural world—of the ecosystems that sustain biodiversity, the air we breathe, and the waters that nourish life on Earth—and the well-being of future generations.

Atlantic salmon are one of the richest sources of omega-3 fatty acids, essential for protecting heart health, reducing inflammation, and improving brain function. Their nutritional value makes them a powerful ally in promoting human well-being. But they are more than just a delicious and nutritious food source—they are critical to ecological balance. As keystone species, their survival underpins the health of freshwater and marine ecosystems, supports biodiversity, and contributes to climate regulation. Yet, wild Atlantic salmon populations are teetering on the brink of extinction due to habitat loss, overfishing, pollution, and climate change.

Protecting Atlantic salmon is not merely about saving a species; it is about preserving the ecosystems that provide clean water, oxygen, and food security, while also supporting the economic stability of communities that depend on them. Wild Atlantic salmon contribute significantly to society, not only as a source of food but also by driving economic growth through industries like fishing and eco-tourism. They offer non-material benefits as well, such as recreational and cultural fishing experiences (North Atlantic Salmon Conservation Organization, n.d.). Moreover, conservation efforts protect cultural heritage, especially for Indigenous peoples, whose traditions and livelihoods are deeply intertwined with this remarkable species.

By protecting Atlantic salmon, we are not only safeguarding a species but ensuring the health of ecosystems, the economic stability of communities, and the well-being of future generations. Through collaborative efforts—driven by policy, technology, and community action—we can secure a future where Atlantic salmon continue to thrive, sustaining the balance of nature for generations to come.

Atlantic Salmon’s Role in Ecosystems 

Atlantic salmon are a keystone species, meaning they have an outsized impact on their environment. Their presence helps maintain biodiversity, regulates ecosystems, and supports natural processes that benefit both nature and humans. Here’s how:

  • Clean Water Production: Atlantic salmon migrations contribute nutrients that support aquatic plants, which filter and purify water. Healthy salmon populations create ecosystems that are better equipped to remove pollutants, benefiting humans and aquatic life alike.

  • Oxygen Generation: Marine ecosystems, driven by phytoplankton, produce up to 70% of the Earth's oxygen. By transporting nutrients between marine and freshwater systems, salmon indirectly support oxygen production in aquatic ecosystems, including algae and aquatic plants in rivers and streams.

  • Nutrient Cycling: When salmon die after spawning, their decomposing bodies release marine-derived nutrients into freshwater systems. These nutrients enrich soil, boost plant growth, and sustain insects and aquatic life, which in turn support agriculture and ecosystems humans depend on.

  • Climate Regulation: Salmon migrations enrich riparian zones, supporting trees and plants that store carbon and stabilize the climate. In oceans, they play a role in food webs that sustain phytoplankton, which absorb vast amounts of carbon dioxide.

Without Atlantic salmon, these critical processes weaken, affecting everything from clean air to food security.

Cultural and Economic Importance

Atlantic salmon hold deep cultural significance, especially for Indigenous peoples who have relied on them for sustenance and ceremonial practices for centuries. For these communities, salmon represent resilience and harmony with nature, and traditional fishing practices reflect a deep respect for ecological balance.

Economically, Atlantic salmon are vital to coastal and rural communities. Commercial and recreational fishing industries generate billions of dollars annually, supporting jobs, tourism, and local businesses. Recreational fishing also attracts international enthusiasts, boosting eco-tourism and contributing to the livelihoods of small businesses.

Conservation efforts further create opportunities for green jobs in habitat restoration, sustainable aquaculture, and environmental monitoring, ensuring communities benefit from protecting this iconic species.

Challenges to Atlantic Salmon Survival

Increasing Water Temperatures

Rising water temperatures present one of the most critical threats to Atlantic salmon survival. Salmon are cold-water fish that thrive in specific temperature ranges, and their life cycle is highly sensitive to temperature changes, particularly in freshwater habitats. A 1°C increase in river temperatures reduces juvenile survival rates by 10% (Global Change Biology, 2020).

Warmer waters hold less oxygen, which can lead to dangerously low oxygen levels, known as hypoxic conditions, that are deadly for salmon and other aquatic life. Higher temperatures also speed up the development of salmon eggs and young fish, sometimes causing them to hatch when their usual food sources are not available. This mismatch in timing, like arriving at a dinner party after the food is gone, can greatly reduce their chances of survival.

These temperature changes are made worse by shifting weather patterns caused by changes in the atmosphere. Droughts and flooding are becoming more common and intense, which damages salmon habitats by washing sediment into the water, wearing away riverbanks, and reducing access to cool, shaded areas that salmon rely on to survive. Together, these challenges create a harsh environment for salmon, especially during their most vulnerable life stages.

In oceanic systems, warming sea temperatures disrupt prey availability, such as plankton and small fish, destabilizing food webs that sustain salmon during their marine phase. Salmon often expend more energy migrating further to find sustenance, reducing their chances of successfully returning to spawn.

Aquaculture Risks

The rapid expansion of salmon aquaculture, while meeting global seafood demand, introduces ecological risks that jeopardize wild salmon populations. Fish farms act as reservoirs for diseases and parasites, such as sea lice, which can spread to wild populations. For instance, sea lice infestations originating from fish farms have been linked to the mortality of over 80% of wild juvenile pink salmon in British Columbia's Broughton Archipelago (David Suzuki Foundation, 2007)

Escaped farmed salmon interbreed with native populations, blending their traits and causing genetic homogenization, which reduces the wild population's diversity. This is like mixing two vibrant paint colors until the unique vibrancy of each is lost, leaving a uniform version that lack adaptability. This loss of genetic diversity weakens the salmon's ability to respond to environmental changes, making them more vulnerable to threats.

At the same time, nutrient runoff from fish farms—such as uneaten feed and fish waste—leads to eutrophication. This process acts like over-fertilizing a garden, causing algae blooms to grow out of control. When the algae die and decompose, they consume oxygen in the water, leaving little for salmon and other aquatic life to survive, severely damaging aquatic ecosystems.


Sustainable aquaculture practices, such as closed-containment systems and improved monitoring, are often considered key solutions for balancing seafood production with wild salmon conservation. Closed-containment systems, which function like "fish farms with walls," are designed to keep fish, waste, and uneaten feed contained, preventing pollution and escaped farmed salmon from affecting surrounding environments. By isolating farmed fish from natural waterways, these systems aim to reduce risks like genetic homogenization and the spread of parasites to wild populations.

While closed-containment aquaculture systems are designed to mitigate environmental risks such as pollution and the escape of farmed salmon, they are not without challenges. The confined conditions can create an environment where diseases spread more quickly among farmed fish, posing a potential threat to both farmed and wild populations if pathogens escape. Insufficient monitoring exacerbates this risk, potentially undermining the sustainability of these systems. Rigorous disease management protocols, such as advanced water filtration, regular health assessments, and quantitative monitoring of pathogen movement, are essential to address these challenges effectively. As emphasized by the Canadian Science Advisory Secretariat, implementing thorough disease risk assessments and identifying critical control points are key measures to reduce disease risks and ensure the long-term viability of closed-containment systems (Canadian Science Advisory Secretariat, 2008).

Habitat Fragmentation and Loss

Habitat fragmentation caused by human infrastructure significantly disrupts the life cycle of Atlantic salmon. Dams, roads, and urban development block migration routes, preventing salmon from reaching critical upstream spawning grounds. While fish ladders and bypass systems have been implemented in some areas, many structures remain impassable or ineffective.

Altered flow regimes from dams disrupt the timing of salmon migrations, making it harder for them to reach their spawning grounds. Meanwhile, habitat degradation from deforestation, urbanization, and agriculture further diminishes the quality of river ecosystems. Healthy riparian zones—the green borders along a river that act like nature’s protective blanket—are often destroyed by these land-use changes. These zones are vital for salmon survival, providing cool shade, stabilizing soil to prevent erosion, and offering food and shelter for aquatic life. Without them, rivers lose their ability to support thriving salmon populations.

Habitat loss also allows invasive species like smallmouth bass to encroach into salmon habitats, outcompeting or preying on juvenile salmon. Rising water temperatures further exacerbate this issue by expanding the range of these non-native predators.

Pollution

Pollution from agricultural runoff, industrial discharges, and urban development adds another layer of threat to Atlantic salmon. Chemicals like pesticides and fertilizers contaminate waterways, leading to harmful algal blooms that deplete oxygen levels and create toxic conditions. Heavy metals, such as mercury and lead, accumulate in the food web, posing long-term health risks to salmon and the predators that consume them.

River acidification, caused by atmospheric deposition of sulfur and nitrogen compounds, lowers pH levels, impairing salmon's ability to regulate their internal chemistry. This makes survival in freshwater environments increasingly difficult. Additionally, microplastic pollution has emerged as a growing concern, as these particles are ingested by salmon, disrupting their digestive systems and overall health.

Overfishing and Ocean Acidification

While regulations have reduced illegal fishing in some regions, overfishing remains a critical threat in areas with weak enforcement or international cooperation. Overfishing depletes salmon populations, particularly in regions already stressed by other challenges like habitat loss and pollution.

Ocean acidification, driven by the absorption of excess carbon dioxide, weakens the shells of prey species such as crustaceans, disrupting the food web salmon depend on during their marine phase. These disruptions reduce the availability of prey and compound the challenges salmon face in maintaining energy reserves for spawning.


 Human Behavior and Conservation Gaps

Human behaviors significantly impact salmon conservation efforts. Research from Purdue University emphasizes that promoting specific, actionable behaviors—such as choosing sustainably sourced seafood—is more effective than general awareness campaigns. Certifications like the Marine Stewardship Council (MSC) label help consumers support sustainable fishing practices.

However, public awareness and accessibility to sustainable seafood options remain barriers. Educational campaigns and incentives can bridge this gap, encouraging consumers to adopt environmentally responsible habits. These collective actions benefit not only Atlantic salmon but also the broader ecosystems that support biodiversity and human well-being.

Conservation Solutions That Work


Community-Driven Efforts

The Penobscot River in Maine once thrived as a vital artery of life, where Atlantic salmon embarked on ancient journeys, leaping through cascades and swift currents to return to their birthplace. For centuries, the river sustained not only the salmon but an entire ecosystem of creatures and communities. Over time, however, the river's rhythm faltered. Outdated dams blocked migration routes, pollution clouded its waters, and the salmon’s return dwindled to a heartbreaking few, leaving the river a shadow of its former self.

Yet, where the river had been silenced, a new song began. The Penobscot River Restoration Project—a transformative, community-driven initiative—brought together conservationists, Indigenous leaders, local fishermen, and scientists. Over a decade, this collaborative effort successfully removed outdated dams and reconnected approximately 2,000 miles of habitat for Atlantic salmon and other sea-run fish species (Natural Resources Council of Maine, 2013). Guided by ecological science and informed by local stakeholders, the project ensured that conservation efforts aligned with the cultural and economic priorities of the region.

The restoration project transformed the Penobscot into a thriving habitat, significantly enhancing fish passage and habitat connectivity. By 2021, the Maine Department of Marine Resources recorded 1,520 returning adult Atlantic salmon, the highest count in over a decade—a powerful testament to the project’s success (NOAA Fisheries, 2021). Salmon, once scarce, now flash like silver ghosts in the sunlight as they leap upstream, reclaiming their ancestral waters.

This revival extended beyond salmon. River herring populations soared, with more than 6 million migrating through restored sections of the river to their spawning habitats—an astonishing increase of over 1,000% compared to pre-restoration counts (NOAA Fisheries, 2021). Their return revitalized the ecosystem: otters slid into the clear waters, herons waded gracefully in the shallows, and the riverbanks flourished, enriched by the nutrients carried by salmon from the sea.

The transformation also renewed the human spirit. Local fishermen, who had once despaired at the salmon’s decline, now marveled at their return—a tangible testament to the power of community action. For the Indigenous peoples of the region, the salmon’s resurgence reaffirmed their spiritual and cultural ties to the land. The project not only restored the river but rekindled a profound connection between people and nature, fostering a shared sense of stewardship and long-term care for the Penobscot’s future.

Community-based conservation efforts like the Penobscot River Restoration Project demonstrate the power of collaboration. By integrating ecological science with local engagement, these initiatives ensure that conservation is both evidence-based and culturally relevant. Local stakeholders help align goals with community priorities, reducing resistance to change and creating a shared vision for the future. The Penobscot’s recovery shows that when people come together to honor the natural world, the rewards ripple outward—strengthening ecosystems, revitalizing economies, and deepening the bonds that tie us to the land.

Innovative Technologies

On a crisp morning along a remote riverbank in New Brunswick, researchers waded into the cool waters, not to cast nets or place traps, but to collect a few small vials of water. Within these seemingly ordinary samples lies a revolution in conservation: environmental DNA, or eDNA. This technique allows scientists to analyze the genetic material that organisms, like salmon, leave behind in the water—tiny traces from their skin, scales, or mucus. Like nature’s fingerprint, eDNA reveals where salmon have been without the need to see or catch them directly, offering a non-invasive way to monitor their presence while leaving their habitats in tact.


Environmental DNA (eDNA) analysis has demonstrated a significant improvement in the detection rates of juvenile salmon compared to traditional sampling methods. For instance, a study by Tillotson et al. (2018) found that eDNA sampling detected salmon presence at 100% of sites, whereas traditional methods detected them at only 66% of the same sites. This indicates that eDNA can enhance detection efficiency by approximately 34%. This non-invasive and cost-effective technology is transforming conservation, allowing scientists to pinpoint priority habitats and monitor population trends in real-time.

When paired with GIS mapping, eDNA reveals a detailed map of migration routes and spawning grounds, allowing conservationists to create adaptive management plans. These plans work like a GPS that updates as you drive, enabling conservationists to adjust their strategies based on new information or changing environmental conditions. From the smallest tributaries to vast marine ecosystems, this combination of molecular ecology and innovative technology demonstrates how we can work in harmony with nature. Just as Atlantic salmon navigate the intricate pathways between ocean and stream, these tools connect data, ecosystems, and the people dedicated to protecting them.

Policy Impacts

The Endangered Species Act (ESA) has been instrumental in protecting Atlantic salmon and other at-risk species, standing as a pivotal construct of U.S. conservation policy. By designating critical habitats, regulating harmful activities, and establishing recovery plans, the ESA addresses systemic threats that drive species toward extinction. Its comprehensive framework not only conserves biodiversity but also supports broader ecological and economic goals.

Illegal, unreported, and unregulated (IUU) fishing accounts for approximately 20% of the global fish catch, leading to significant economic losses estimated between $10 billion and $23.5 billion annually (Our Shared Seas, 2019). In 2019, the United States imported an estimated $2.4 billion worth of seafood derived from IUU fishing, representing nearly 11% of total U.S. seafood imports (U.S. International Trade Commission, 2021). The ESA plays a crucial role in combating IUU fishing by regulating activities like overfishing and habitat destruction, which directly impact endangered species such as Atlantic salmon. Enforcing these regulations helps reduce illegal fishing practices, safeguards marine ecosystems, and bolsters the economic stability of communities reliant on legal fisheries. By mitigating the economic losses associated with IUU fishing, the ESA also strengthens the overall health of the fishing industry and the broader economy.

ESA-related initiatives have further contributed to salmon conservation through habitat restoration projects such as dam removal and riparian zone reforestation. These efforts have improved spawning grounds and migration corridors, creating healthier environments for salmon and other aquatic species. Investments in these projects demonstrate the Act’s capacity to restore interconnected habitats that are essential for species recovery and ecosystem stability.

The systemic changes enabled by the ESA underscore its effectiveness as a conservation tool. By designating critical habitats, the Act ensures the preservation of essential spawning grounds and migration routes, safeguarding the habitats that sustain Atlantic salmon throughout their life cycle. Additionally, the ESA regulates harmful industrial activities such as pollution, deforestation, and overfishing, alleviating stressors on fragile ecosystems. Stricter enforcement mechanisms ensure compliance with these regulations, further supporting salmon recovery efforts. The Act also provides financial incentives for restoration projects, including the removal of outdated dams and the reforestation of degraded riverbanks, which yield tangible benefits for biodiversity and ecosystem health.

Finally, the ESA has fostered public awareness and grassroots engagement through education and outreach initiatives. These programs encourage community-level support for sustainable conservation practices, ensuring that efforts to protect Atlantic salmon are collaborative and enduring. Together, these systemic changes illustrate the ESA’s pivotal role in addressing the complex challenges facing endangered species and the ecosystems they depend on.

Actionable Recommendations for Policymakers

Building on the ESA’s successes requires addressing emerging challenges with targeted, actionable strategies. Strengthening aquaculture regulations is essential to mitigate risks posed by open-net salmon farming, including disease transmission, genetic homogenization, and water pollution. Policymakers should enforce stricter rules on aquaculture operations and support research into closed-containment systems, which minimize environmental impacts. These systems require stringent oversight and comprehensive management to mitigate risks such as disease outbreaks and ensure their long-term sustainability.

Expanding habitat restoration funding is another critical step. Federal and state governments should allocate resources to projects like dam removal, reforestation of riparian zones, and water quality improvement initiatives. Providing financial incentives for private landowners to participate in these efforts can further foster community engagement in conservation. Enhanced monitoring and enforcement efforts are equally important. Policymakers should invest in advanced technologies like environmental DNA (eDNA) to efficiently track salmon populations and habitat conditions while bolstering enforcement of existing regulations to ensure compliance and deter illegal activities.

To address the challenges of climate change, policymakers must promote climate-resilient strategies. Investments in research and the development of adaptive management plans can mitigate the impacts of rising water temperatures and altered precipitation patterns. Riparian reforestation, for instance, provides natural cooling for waterways and buffers against extreme weather events, ensuring healthier habitats for salmon. Finally, fostering collaboration across jurisdictions is essential for coordinated conservation efforts. Policymakers should work with local governments, Indigenous communities, and international organizations to align strategies and share resources. Cross-border agreements to protect migratory salmon populations are vital for ensuring sustained conservation efforts across regions.

Habitat Restoration Projects

In Washington State, the Elwha River stood as a testament to how human intervention could choke the life out of a once-thriving ecosystem. For more than a century, two massive dams blocked the river, silencing the rush of salmon migrations that had sustained the watershed and the communities surrounding it. Without their vital connection to the sea, the salmon populations dwindled, and with them, the balance of the entire ecosystem began to unravel.

Then, in one of the most ambitious habitat restoration efforts in U.S. history, the Elwha and Glines Canyon dams were removed between 2011 and 2014. What followed was nothing short of miraculous. The river, freed from its constraints, began reshaping its course, carrying sediment downstream to rebuild deltas and nourish aquatic habitats. As the river flowed unimpeded, Atlantic salmon—alongside other migratory fish—began to return, reclaiming their ancestral spawning grounds.

The effects rippled outward. Riparian zones along the riverbanks sprang to life as native vegetation took hold, providing shade and stabilizing the soil. Eagles and bears returned, drawn by the renewed abundance of fish. Even coastal ecosystems benefited, as the reconnected river deposited vital nutrients into estuaries, fueling marine food webs.

The Elwha restoration serves as a powerful example of how dam removal can revive ecosystems. Similar efforts, like the Penobscot River restoration, show that strategic interventions, informed by science and supported by local communities, can create lasting change.

Beyond dam removal, restoration projects often include reforesting riparian zones with native trees to shade waterways and prevent erosion. In other cases, conservationists reshape riverbeds to mimic natural flow patterns, ensuring salmon have the gravel beds they need to spawn. Each action builds on the others, reinforcing the resilience of the ecosystem as a whole.

The story of the Elwha River reminds us that habitat restoration is more than a technical exercise—it’s a renewal of life itself, offering a second chance for rivers, fish, and the interconnected web of species that depend on them. With each dam removed and each tree planted, we take one step closer to a future where the ancient migrations of salmon can continue uninterrupted, as they have for millennia.

How You Can Make an Impact


Protecting Atlantic salmon requires a collective effort, where individual actions, organizational support, and policymaker initiatives align to create meaningful change. Here’s how different stakeholders can contribute:
