Justification

At the global population level, Sockeye Salmon are assigned a Red List status of Least Concern (LC). The median and mean rate of change across the 62 assessed populations indicate an expanding global population (9.0 and 72.4 % increase, respectively, over the past three generations), thus there is no evidence of risk to the species under Red List A2 criterion. With an estimated geographic range of 11.5 million km², there is no evidence of threat to the global population under criterion B1 (Table 1). Similarly, at 1.9 million km² of current occupancy (freshwater basin area), there is no evidence of threat under criterion B2 (Table 1). Approximately 7% of the historical range of Sockeye Salmon has been lost due to localized extinction events, but we conclude the species is not threatened globally.
