Video shows salmon injured by unlivable water temperatures after heatwave

A conservation group recorded the video after a heatwave in the Pacific north-west on a day when water temperatures breached 70F

Salmon in the Columbia River were exposed to unlivable water temperatures that caused them to break out in angry red lesions and white fungus in the wake of the Pacific north-west's record-shattering heatwave, according to a conservation group that has documented the disturbing sight.

In a video released on Tuesday by the non-profit organization Columbia Riverkeeper, a group of sockeye salmon swimming in a tributary of the river can be seen covered in injuries the group say are the results of stress and overheating.
