the sores and bloated belly's the fish are displaying is very telling that something besides warm water is at play here.

An estimated quarter-million salmon, more than half of the spring spawning run up the Columbia River, perished, probably because of a disease that thrives in warm water and causes gill rot, officials said. Normally cool streams in the river basin are 13 degrees warmer than the 60 degrees preferred by salmon, Brigham said.
Only 272,000 out of the more than 507,000 sockeye salmon that have swum between two dams along a stretch of the lower Columbia River have survived the journey, said Oregon Department of Fish and Wildlife fisheries manager John North.
So Fukushima is heating up the Pacific Ocean?
The warmer-than-usual water temperatures are promoting bacterial infections in the sockeye, Korth said.
“These salmon are constantly getting scraped, scratched and poked as they go over rocks and climb fish ladders and escape predators,” he said. “That’s not a big problem in cold water, but in warm water the bacteria that’s in an aquatic system gets around the wounds and proliferates faster. We’re seeing big gaping sores on these fish.”

Uh huh.
And the tributaries to the Columbia River as well. Cuz warm water flows upstream. Somehow...not sure how..but it does.

Scientists fear toxic algae bloom spreading on Pacific coast
And here's another possible contributing factor (found while looking for info on Middle Eastern 'heat dome':
An additional concern relates to salmon stock. The bloom has almost no crustaceans, but instead has a large number of gelatinous zooplankton, which is worrisome, Perry said. Young salmon typically migrate out of rivers and migrate along the coast of the Island at this time of year. “Because they’re small, they need to feed a lot and grow quickly to avoid predators. But with the lack of crill and other crustaceans, there is a concern they won’t find as much food,” Perry said.
The consequences could be seen in lower salmon stocks returning to rivers in two to four years, he said.
