In a remarkable testament to environmental resilience, young Atlantic salmon have triumphantly returned to three rivers in north-west England, marking their first confirmed presence since 2015 and offering a beacon of hope for a species critically endangered in Britain.

The Environment Agency confirmed the discovery of these juvenile salmon in the Mersey, Bollin, and Goyt rivers, representing an extraordinary journey from the Arctic Circle to their native spawning grounds. This breakthrough comes just two years after the species was declared critically endangered, signaling a potentially significant ecological recovery.

Mark Sewell from United Utilities highlighted the dramatic transformation, noting that rivers once considered 'biologically dead' in the 1980s now support thriving ecosystems. These waterways have gradually recovered, becoming hospitable to pollution-intolerant fish species and demonstrating nature's remarkable capacity for regeneration.

The salmon's survival has been challenged by multiple threats including climate change, pollution, and invasive species, which contributed to a staggering 30-50% population decline since 2006. Despite these obstacles, the fish have managed to navigate complex river systems, successfully spawning in gravel beds after spending two to three years feeding in Arctic waters.

However, challenges remain. Several rivers still contain significant barriers to salmon migration, such as dams and locks. The River Tame and River Irwell, for instance, remain blocked by weirs and locks, preventing salmon from accessing potential spawning grounds. Local conservation advocates like Mike Duddy from the Salford Friendly Anglers Society are calling for the construction of fish passes to further support salmon restoration.

The Environment Agency plans to conduct a comprehensive salmon distribution study in early 2026, utilizing advanced eDNA sampling techniques to assess the extent of the species' recovery. This scientific approach will provide crucial insights into the salmon's current population and potential future conservation strategies.

As these resilient fish continue their remarkable comeback, their story serves as a powerful reminder of nature's regenerative potential and the critical importance of sustained environmental protection efforts.
