- Alaska’s unprecedented summer heatwave has killed several salmon varieties including sockeye, chum and pink salmon.
- After being alerted by locals, scientists discovered 850 dead salmon still carrying eggs along Alaska’s Koyokuk River (total dead salmon population from river estimated to be 4x-10x larger).
- The lack of lesions, parasites or infections among the dead salmon signaled heatwave-induced deaths.
- Alaska’s 2019 heatwave has exceeded scientists worst-case scenarios for year 2069.
- Given that the dead salmon were carrying eggs puts the future salmon population at risk.
