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.
The salmon had been traveling upstream in the Columbia River from the ocean, to return to their natal spawning areas, when they unexpectedly changed course, explained Brett VandenHeuvel, the executive director of Columbia Riverkeeper. He described the sockeye as veering off to the Little White Salmon River, a tributary of the Columbia River where the video was recorded, in an effort to essentially “escape a burning building”
The salmon in the video won’t be able to spawn in the tributary and are expected to die from disease and heat stress.
