Young Atlantic Salmon Return to North-West England Rivers

For the first time since 2015, young Atlantic salmon have been observed in three rivers in north-west England: the Mersey, Bollin, and Goyt. This development marks a notable environmental turnaround for a species that was declared critically endangered in Britain in 2023. The successful sightings indicate that these salmon have traveled from the Arctic Circle to spawn, a journey that underscores their resilience despite previous population declines.

The survival of Atlantic salmon in Britain has been jeopardized by several factors, including climate change, pollution, and the presence of invasive non-native species. Since 2006, British salmon populations have experienced a decline of 30-50%. However, recent improvements in river ecosystems have contributed to the recovery of various fish species. Mark Sewell, a wastewater catchment manager at United Utilities, noted that significant stretches of river were biologically dead in the 1980s, but today they support thriving ecosystems, including pollution-intolerant fish species.

Despite the positive signs of recovery, Atlantic salmon face challenges in their migration due to blockages in rivers, such as dams and weirs. While they can swim up the Mersey to spawn in the Bollin and Goyt, obstacles in other rivers, like the River Tame and River Irwell, hinder their movement. Mike Duddy from the Salford Friendly Anglers Society emphasized the need for fish passes to facilitate salmon migration, stating that many people would appreciate seeing salmon return to rivers like the Roch and Irk.

The Environment Agency has announced plans to conduct a new salmon distribution study in early 2026, utilizing environmental DNA (eDNA) sampling to better understand the spawning range and assess the extent of recovery. A spokesperson expressed excitement about the successful spawning of salmon, given their critically endangered status. This study aims to provide valuable insights into the ongoing conservation efforts for Atlantic salmon in the region.

While the return of young Atlantic salmon is a positive development, there are concerns regarding the long-term sustainability of their populations. Critics argue that without addressing the barriers to migration and ongoing environmental threats, the recovery may be short-lived. The need for infrastructure improvements, such as fish passes, is seen as crucial for ensuring that salmon can access their historical spawning grounds.

• “If we wanted to do something for our future generations, now is the time to build a fish pass because there are huge numbers of people that would love to see salmon returning to the Roch and Irk, as well as the rivers in Bolton.” — Mike Duddy, Salford Friendly Anglers Society

The return of young Atlantic salmon to north-west England rivers represents a significant step forward in environmental recovery efforts, but ongoing challenges remain that require attention to ensure the species' future sustainability.
