A conservation group recorded the video in a tributary of the Columbia River on a day when water temperatures breached 70F
Salmon in the Columbia River were nearly roasted to death when water temperatures rose during 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 angry red lesions and white fungus, the results of stress and exposure to extreme temperatures.
