Risks Facing the Southern and Northern Complexes
The biological status of these fish is equally concerning. According to the 2026 assessment, Southern NEAC returns are currently “suffering reduced reproductive capacity,” with 2025 estimates marking the lowest in the entire time-series. While Northern stocks have shown more resilience, the multi-sea-winter (MSW) salmon in the north are now considered “at risk of suffering reduced reproductive capacity.”
ICES warns that the aggregation of data can often hide the dire reality of individual river stocks. To combat this, the report emphasizes that “mixed-stock fisheries present particular threats and should be managed based on the individual status of all stocks exploited in the fishery.”
Broad Conservation and Environmental Action Required
The advice extends beyond fishing quotas, pointing to a range of anthropogenic and environmental stressors. Marine productivity is being hampered by declining post-smolt survival rates, which have fallen since the 1970s. Additionally, the expansion of non-native pink salmon and the impact of marine aquaculture—including sea lice and escapees—pose ongoing threats to wild populations.
ICES concludes that “all non-fisheries related anthropogenic mortalities in both freshwater and the marine environments should be minimized” and calls for the restoration of habitat connectivity and biological quality to support the recovery of the species.
