Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Silver salmon face severe population declines due to habitat destruction from dam construction, river channelization, and urban development that blocks migration routes and degrades spawning grounds. Climate change is altering ocean temperatures and acidification levels, disrupting marine food webs and affecting survival rates during the oceanic phase of their lifecycle.

Threat summary

Habitat

Cold-water rivers and streams for spawning and juvenile development, migrating to marine environments including coastal waters and open ocean for adult feeding and growth. Requires clean gravel beds in freshwater systems and productive marine ecosystems with temperatures typically below 15°C.

Frequently asked questions

Why is silver salmon classified as Critically Endangered?
silver salmon is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Silver salmon face severe population declines due to habitat destruction from dam construction, river channelization, and urban development that blocks migration routes and degrades spawning grounds. Climate change is altering ocean temperatures and acidification levels, disrupting marine food webs and affecting survival rates during the oceanic phase of their lifecycle.
Where does silver salmon live?
silver salmon occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to silver salmon?
The main threats to silver salmon are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
